Abstract
Type 2 diabetes (T2DM) presents an enormous global healthcare challenge, especially among rural communities due to limited access. To overcome this, many low- and middle-income countries are resorting to task shifting, using community health workers (CHWs) for diabetes management. However, its successful implementation depends on the practice behaviours and knowledge of these workers.
This cross-sectional study from rural South India aimed to evaluate the proficiency of 275 CHWs in diabetes screening and management. A customized questionnaire, developed through experts and government was used to evaluate the practice behaviours and knowledge. Analytical methodologies consisted of descriptive statistics, logistic regression, and mosaic plots for comprehensive data interpretation.
Results showed significant deficiencies of mean correct practice behaviours at 48 and 50% respectively. The identified gaps included diabetes diagnosis, HbA1c testing, diet, self-management, complications screening and risk assessment. In several areas, correct practice behaviour was reported by a relatively large number of CHWs despite incorrect answers to the related knowledge questions such as referral to the health centres, self-management and calculation of diabetes risk assessment.
Addressing these deficiencies requires a thorough needs assessment and tailored training for improved diabetes management by CHWs. Training of CHWs, should not only identify prior knowledge and/or behaviour but also their interrelationship to help create a robust and flexible set of practice behaviours.

1. Introduction
Type 2 diabetes mellitus (T2DM) is a pressing global health concern, with an estimated 537 million adults living with the condition worldwide, and 74.2 million cases in India alone [1]. The World Bank data estimates that in 2021, the prevalence of T2DM in Indian adults was 5 per cent [2]. The International Diabetes Federation (IDF) reported that nearly 50% of persons are living with undiagnosed diabetes in India[1]. The report also estimates that this Indian burden is set to grow to 125 million by 2045 significantly affecting a major proportion of its population[1]. Recent trends have indicated the growing prevalence of diabetes amongst lower socioeconomic stratum and rural populations especially in LMICs[3]. With nearly 65% of Indians residing in such areas[4], diabetes poses a huge threat to the population. Prolonged exposure to high blood glucose levels can lead to severe health consequences, particularly micro- and macrovascular complications often leading to morbidity and mortality[1]. An Indian study showed that patients already have some form of diabetic retinopathy at the time of their eye clinic visits with a potential for blindness if left untreated[5]. Thus, detection and management of T2DM in these areas is extremely critical but is a challenge due to factors like limited access to healthcare services especially in rural areas, lack of trained personnel, unsatisfactory health-seeking behaviour and long travel distances [3,6,7,8,9]. Therefore, healthcare systems must develop innovative service models to overcome these barriers.
Task shifting of certain duties of medically trained healthcare workers in rural areas to frontline community health workers (CHWs) is one of the methods to improve the accessibility of care and to reduce the burden on the more qualified health workforce [10]. This approach is being carried out by several developing countries [11,12,13,14,15,16]. In India Multipurpose Health Workers/Assistants and Accredited Social Health Activists, typically members of the local communities, are nowadays involved in task shifting in various national health programs for the prevention and management of diabetes, cardiovascular disease, cancer, and stroke[11,17,18,19,20,21]. However, before entrusting the CHWs with the management of the entire spectrum of diabetes screening & management, along with the medical officers, we need to ascertain their capabilities in carrying out the prescribed duties. Evidence reveals a lack of knowledge among these health workers [22,23,24] and we need to better understand what these gaps in knowledge and associated practice behaviours are.
The current study was undertaken to define the current practice behaviours of CHWs responsible for screening and managing diabetes in rural South India and to determine if these behaviours were associated with specific gaps in knowledge. These data would be used as the starting point for the development of a specific training program tailored to the needs of these healthcare workers.
Hence the research question of this study is: what are the existing gaps in the practice behaviours and knowledge of the CHWs involved in screening and management of diabetes in rural South India?
2. Methodology
This study had a cross-sectional design and included the CHWs involved in diabetes screening and management at the community level and working in eight healthcare administrative regions of Telangana, South India between August 2021 to March 2022. Telangana has approximately 21,400,000 (21.4 million) rural inhabitants, which is almost 62% of its total population. These workers are primarily tasked with population enumeration, home screening and motivating patients to maintain a healthy lifestyle and attend regular complication screening supervision of tasks undertaken by junior cadres conduct meetings with local essential stakeholders, oversee the data from their health centre and share the data with the authorities.
We used a questionnaire to assess practice behaviour of the participants and associated knowledge. To develop this questionnaire, we first interviewed senior government officials and medical officers about the common situations faced by CHWs in the community. In these interviews, the most important practice behaviours of the CHWs were identified and the knowledge deemed conditional for these practice behaviours. The questionnaire was developed in both English and Telugu (vernacular language) consisting of 19 questions. This was then piloted with 10 CHWs not included in the study. Based on the feedback received, it was edited and eventually, the validated questionnaire consisted of 17 questions, 10 on practice behaviours and 7 on associated knowledge, as shown in Table A1 and summarized in Table 1.
We administered the questionnaire to 275 CHWs on paper in a face-to-face manner. Because of the diversity, in reading and linguistic skills (due to differences in dialects) the content of the questionnaire was explained by two research assistants during group sessions of approximately 25-30 CHWs per session. After all the queries of the CHWs were answered by the research assistants, participants were asked to fill in the answers individually and arrangements were made to ensure no discussion among the participants during this phase of the meeting was possible. The duration of each session was approximately 3.5-4 hours. Each session was presided over by two research associates and 8 meetings were held, in the region where the CHWs were working. The two research associates were trained beforehand and were provided with a handbook to assist them in their roles.
A digital version of the questionnaire was created for each participant in Microsoft (MS) Access and data were imputed by coding for correct and incorrect answers along with missing values. The imputed data were cross-verified by the lead researcher and wherever an error was discovered, those physical forms were accessed again to rectify the error. To ensure the veracity of the data, 10% of participants were contacted telephonically for verification. Once confirmed, the data were saved as an Excel workbook which was exported to STATA version 17 for analysis. For scoring the answers to each question, each correct answer was graded as 1 and a wrong, a double answer or no answer was graded as zero. In the initial phase, we asked the government officials and the doctors involved in the development of the questionnaire for the minimal number of correct answers and they formulated a benchmark of 75% correct answers, which we used as an external benchmark for sufficient practice behaviours and knowledge.
2.1. Statistical Analysis
The data were analyzed using mean + standard deviation, median with interquartile ranges (IQR) and frequencies wherever appropriate. The association between correct practice behaviours and their associated knowledge was explored using logistic regression to better understand the relationship between specific gaps in the practice behaviours and knowledge. Finally, to study the relation of correct practice behaviors with incorrect knowledge we used mosaic plots as graphical representations. These plots are divided into four parts, each part depicts the relationship between participants’ practice behaviours (Correct or Incorrect) with the participant’s knowledge (Correct or Incorrect). All the significant results were tabulated and are presented in the results section. More details on the plots and the relationships can be found in Appendix A.3.
3. Results
All participants (n=275) filled in the questionnaire; all were females with a mean age of 38.0 + 7.1 years. A majority (approx. 94%) completed high school. The median (IQR) work experience was 10 years (6-15 years). The median overall number of correct answers was 8 (7-10) out of 17 questions. Only 11 participants (4%) crossed the 75% external benchmark of correct answers (two participants had 14 and nine had 13 correct answers).
In the practice behaviour questionnaire the median overall number of correct answers was 5 (IQR 4-6) out of 10; only 9 participants (3.3%) crossed the 75% benchmark. The correctly answered percentages for each of the questions are depicted in Table A2 of the Appendix A. The participants reported sufficient practice behaviours for hypoglycemia management (78% had correct answers) and frequency of risk screening (75%) while the score for health centre referral, self-management and diabetes signs & symptoms were insufficient (9.8% to 51.3%).
In the knowledge questionnaire the median overall number of correct answers was 4 (IQR 3-4) out of 7, only 15 participants (5.5%) crossed the 75% benchmark. The correctly answered percentages for each of the questions are depicted in Table A3 in the Appendix A. The knowledge about diabetes diet (89.5% correct answers) and diabetic retinopathy/ hypoglycemia (85.1%) was sufficient. The knowledge about diabetes diagnosis & referral, types & self-management and microvascular complications and their screening was insufficient, (30.6% to 57.0% correct answers).
In order to study the association between practice behaviour with knowledge, their overall mean scores were standardized to a scale of 10 with overall mean scores of 5.5 and 4.8 respectively. Practice behaviour was associated with knowledge with an odds ratio of 1.64 and a standardized regression coefficient (beta) of 0.50 with a p-value <0.01. Subsequently, we examined for each pair of questions the association between practice behaviour and knowledge to determine to which extent specific practice behaviour was associated with the knowledge on this topic. In Table 2 the associations with p value below 0.2 are shown. The highest odds ratio (1.99) was observed for the association of microvascular complication screening with the knowledge question on this topic (beta-coefficient of 0.68) with a p-value of 0.09. Nearly the same association was observed for microvascular screening & peripheral neuropathy management with an odds ratio of 1.97 and beta of 0.68 (p= 0.01). The only other pair for which a significant association was observed was for HbA1c testing and diabetes, diagnosis and referral with an odds ratio of only 0.53 and a beta of -0.61 (p=0.04).
We used the mosaic plots to analyze the relationship between correct answers to practice behaviours questions with incorrect knowledge to determine common misconceptions and myths in diabetes care amongst community health workers. There were indeed four such instances where the CHWs answered more than 50% of the correctly answered practice behaviour questions and incorrectly answered knowledge questions. Table 3 depicts these relationships and their frequencies in detail. The mosaic plots can be found in the Appendix A.1.
4. Discussion
The study revealed insufficient practice behaviours and knowledge in ≥ 95% CHWs working in rural areas in India and who are responsible for diabetes screening and management. The identified areas of insufficiency were broadly representative of the core competencies required for effective diabetes management, encompassing diabetes diagnosis and referral, HbA1c testing, diabetes diet, diabetes type and self-management, microvascular complications and their screening, peripheral neuropathy management, and diabetes risk assessment.
Our observations align with existing literature [25,26,27,28,29] documenting incorrect practices among CHWs due to limited or insufficient knowledge. This underscores the need for thorough needs assessments to identify existing knowledge gaps and incorrect practices among CHWs. By addressing these gaps, we can enhance the effectiveness of CHW training programs and ultimately improve diabetes management outcomes.
The summary score of knowledge revealed a stronger association (OR 9.03, p=0.09) with the summary score of practice behaviours compared to associations of knowledge with practice behaviour when each pair of questions was analyzed separately (highest OR 1.99, p=0.09). This observation suggests that while overall knowledge levels tended to positively influence practice behaviours, the relationship was not as evident at the level of specific questions. To further investigate this discrepancy, we employed mosaic plots, which provided insights into potential associations between correct practice behaviours as reported by the respondents and incorrect knowledge. Interestingly, we identified several instances where CHWs reported correct practice behaviours despite possessing incorrect knowledge. This could be attributed to several factors, including prior training, educational differences, or the non-essential nature of specific knowledge for certain practices after adequate training. However, it is crucial to note that even in these cases, incorrect knowledge may hinder the long-term sustainability of the observed correct practice behaviours as it is more likely to push forth incorrect or out-of-date practice behaviours. Thus, focusing solely on either knowledge or behaviour may not yield the desired long-term outcomes. Instead, an integrated, comprehensive approach focusing on both components is essential for effectively equipping CHWs to provide quality diabetes care.
The major strengths of the study were that the questionnaire was developed in close cooperation with the medical staff ultimately responsible for diabetes care as well as using input and feedback from the target group studied. We were therefore able to develop the questionnaire into an accessible tool that could be readable and understandable for all CHWs. In addition, we recruited a relatively large number of participants from multiple rural areas increasing the external validity of our observations. The study also has high generalizability in similar geographies of rural Southeast Asia which bear similarities to our study site like similar diversities of linguistics, education, cultures, practices and socio-demographic factors. Given the time necessary to explain and subsequently fill in the questionnaire, we had to restrict the number of questions for each domain. Moreover, in a few cases, we had to combine two questions into one question, which might have caused difficulty in comprehension for the CHWs and which may have weakened the associations between knowledge and practice behaviour for a specific topic.
Finally, some areas require further exploration, like the correct practice behaviours linked with the incorrect practice behaviours and vice-versa; the barriers and enablers for such relationships also need exploration. The analysis surprisingly discovered that the use of HbA1c testing in daily practice was negatively associated with knowledge of diabetes, diagnosis, and referral: with an odds ratio of 0.53, beta-coefficient of 0.61 and p-value 0.04. This finding, which is currently difficult to explain, needs further exploration in order to improve future training.
5. Conclusions
To conclude, the vast majority of the CHWs involved in diabetes screening and management in rural areas reported inadequate practice behaviour and had insufficient knowledge underlying these behaviours. Defining these gaps in knowledge and practice behaviour is very informative in setting up tailored education programs. However, in several areas, correct practice behaviour was reported by a relatively large number of CHWs despite incorrect answers to the related knowledge questions. Hence, training of CHWs, should not only identify prior knowledge and/or behavior but also their interrelationship to help create a robust and flexible set of practice behaviors that are in line with guidelines on diabetes care, that are continuously changing over time.

Each mosaic plot consists of four sections. Each plot has the number of participants answering knowledge questions on the X-axis and practice behaviour questions on the Y-axis. In the plot, there are two columns, each divided into two parts. The left column shows the number of participants who answered knowledge questions incorrectly. The right column shows the same for correctly answered knowledge questions. The upper part of each column shows the number of participants who answered practice behaviour questions correctly and the lower part who answered incorrectly. Further, the upper right section shows the number of participants who answered both knowledge and practice behaviour questions correctly, and the upper left section shows the number of participants who answered the practice behaviour questions correctly but the knowledge questions incorrectly. The lower left section shows the number of participants who answered both the knowledge and practice behaviour questions incorrectly. The lower right section shows the number of participants who answered knowledge questions correctly but practice behaviour questions incorrectly.

Abstract
Type 2 diabetes (T2DM) presents an enormous global healthcare challenge, especially among rural communities due to limited access. To overcome this, many low- and middle-income countries are resorting to task shifting, using community health workers (CHWs) for diabetes management. However, its successful implementation depends on the practice behaviours and knowledge of these workers.
This cross-sectional study from rural South India aimed to evaluate the proficiency of 275 CHWs in diabetes screening and management. A customized questionnaire, developed through experts and government was used to evaluate the practice behaviours and knowledge. Analytical methodologies consisted of descriptive statistics, logistic regression, and mosaic plots for comprehensive data interpretation.
Results showed significant deficiencies of mean correct practice behaviours at 48 and 50% respectively. The identified gaps included diabetes diagnosis, HbA1c testing, diet, self-management, complications screening and risk assessment. In several areas, correct practice behaviour was reported by a relatively large number of CHWs despite incorrect answers to the related knowledge questions such as referral to the health centres, self-management and calculation of diabetes risk assessment.
Addressing these deficiencies requires a thorough needs assessment and tailored training for improved diabetes management by CHWs. Training of CHWs, should not only identify prior knowledge and/or behaviour but also their interrelationship to help create a robust and flexible set of practice behaviours.

1. Introduction
Type 2 diabetes mellitus (T2DM) is a pressing global health concern, with an estimated 537 million adults living with the condition worldwide, and 74.2 million cases in India alone [1]. The World Bank data estimates that in 2021, the prevalence of T2DM in Indian adults was 5 per cent [2]. The International Diabetes Federation (IDF) reported that nearly 50% of persons are living with undiagnosed diabetes in India[1]. The report also estimates that this Indian burden is set to grow to 125 million by 2045 significantly affecting a major proportion of its population[1]. Recent trends have indicated the growing prevalence of diabetes amongst lower socioeconomic stratum and rural populations especially in LMICs[3]. With nearly 65% of Indians residing in such areas[4], diabetes poses a huge threat to the population. Prolonged exposure to high blood glucose levels can lead to severe health consequences, particularly micro- and macrovascular complications often leading to morbidity and mortality[1]. An Indian study showed that patients already have some form of diabetic retinopathy at the time of their eye clinic visits with a potential for blindness if left untreated[5]. Thus, detection and management of T2DM in these areas is extremely critical but is a challenge due to factors like limited access to healthcare services especially in rural areas, lack of trained personnel, unsatisfactory health-seeking behaviour and long travel distances [3,6,7,8,9]. Therefore, healthcare systems must develop innovative service models to overcome these barriers.
Task shifting of certain duties of medically trained healthcare workers in rural areas to frontline community health workers (CHWs) is one of the methods to improve the accessibility of care and to reduce the burden on the more qualified health workforce [10]. This approach is being carried out by several developing countries [11,12,13,14,15,16]. In India Multipurpose Health Workers/Assistants and Accredited Social Health Activists, typically members of the local communities, are nowadays involved in task shifting in various national health programs for the prevention and management of diabetes, cardiovascular disease, cancer, and stroke[11,17,18,19,20,21]. However, before entrusting the CHWs with the management of the entire spectrum of diabetes screening & management, along with the medical officers, we need to ascertain their capabilities in carrying out the prescribed duties. Evidence reveals a lack of knowledge among these health workers [22,23,24] and we need to better understand what these gaps in knowledge and associated practice behaviours are.
The current study was undertaken to define the current practice behaviours of CHWs responsible for screening and managing diabetes in rural South India and to determine if these behaviours were associated with specific gaps in knowledge. These data would be used as the starting point for the development of a specific training program tailored to the needs of these healthcare workers.
Hence the research question of this study is: what are the existing gaps in the practice behaviours and knowledge of the CHWs involved in screening and management of diabetes in rural South India?
2. Methodology
This study had a cross-sectional design and included the CHWs involved in diabetes screening and management at the community level and working in eight healthcare administrative regions of Telangana, South India between August 2021 to March 2022. Telangana has approximately 21,400,000 (21.4 million) rural inhabitants, which is almost 62% of its total population. These workers are primarily tasked with population enumeration, home screening and motivating patients to maintain a healthy lifestyle and attend regular complication screening supervision of tasks undertaken by junior cadres conduct meetings with local essential stakeholders, oversee the data from their health centre and share the data with the authorities.
We used a questionnaire to assess practice behaviour of the participants and associated knowledge. To develop this questionnaire, we first interviewed senior government officials and medical officers about the common situations faced by CHWs in the community. In these interviews, the most important practice behaviours of the CHWs were identified and the knowledge deemed conditional for these practice behaviours. The questionnaire was developed in both English and Telugu (vernacular language) consisting of 19 questions. This was then piloted with 10 CHWs not included in the study. Based on the feedback received, it was edited and eventually, the validated questionnaire consisted of 17 questions, 10 on practice behaviours and 7 on associated knowledge, as shown in Table A1 and summarized in Table 1.
We administered the questionnaire to 275 CHWs on paper in a face-to-face manner. Because of the diversity, in reading and linguistic skills (due to differences in dialects) the content of the questionnaire was explained by two research assistants during group sessions of approximately 25-30 CHWs per session. After all the queries of the CHWs were answered by the research assistants, participants were asked to fill in the answers individually and arrangements were made to ensure no discussion among the participants during this phase of the meeting was possible. The duration of each session was approximately 3.5-4 hours. Each session was presided over by two research associates and 8 meetings were held, in the region where the CHWs were working. The two research associates were trained beforehand and were provided with a handbook to assist them in their roles.
A digital version of the questionnaire was created for each participant in Microsoft (MS) Access and data were imputed by coding for correct and incorrect answers along with missing values. The imputed data were cross-verified by the lead researcher and wherever an error was discovered, those physical forms were accessed again to rectify the error. To ensure the veracity of the data, 10% of participants were contacted telephonically for verification. Once confirmed, the data were saved as an Excel workbook which was exported to STATA version 17 for analysis. For scoring the answers to each question, each correct answer was graded as 1 and a wrong, a double answer or no answer was graded as zero. In the initial phase, we asked the government officials and the doctors involved in the development of the questionnaire for the minimal number of correct answers and they formulated a benchmark of 75% correct answers, which we used as an external benchmark for sufficient practice behaviours and knowledge.
2.1. Statistical Analysis
The data were analyzed using mean + standard deviation, median with interquartile ranges (IQR) and frequencies wherever appropriate. The association between correct practice behaviours and their associated knowledge was explored using logistic regression to better understand the relationship between specific gaps in the practice behaviours and knowledge. Finally, to study the relation of correct practice behaviors with incorrect knowledge we used mosaic plots as graphical representations. These plots are divided into four parts, each part depicts the relationship between participants’ practice behaviours (Correct or Incorrect) with the participant’s knowledge (Correct or Incorrect). All the significant results were tabulated and are presented in the results section. More details on the plots and the relationships can be found in Appendix A.3.
3. Results
All participants (n=275) filled in the questionnaire; all were females with a mean age of 38.0 + 7.1 years. A majority (approx. 94%) completed high school. The median (IQR) work experience was 10 years (6-15 years). The median overall number of correct answers was 8 (7-10) out of 17 questions. Only 11 participants (4%) crossed the 75% external benchmark of correct answers (two participants had 14 and nine had 13 correct answers).
In the practice behaviour questionnaire the median overall number of correct answers was 5 (IQR 4-6) out of 10; only 9 participants (3.3%) crossed the 75% benchmark. The correctly answered percentages for each of the questions are depicted in Table A2 of the Appendix A. The participants reported sufficient practice behaviours for hypoglycemia management (78% had correct answers) and frequency of risk screening (75%) while the score for health centre referral, self-management and diabetes signs & symptoms were insufficient (9.8% to 51.3%).
In the knowledge questionnaire the median overall number of correct answers was 4 (IQR 3-4) out of 7, only 15 participants (5.5%) crossed the 75% benchmark. The correctly answered percentages for each of the questions are depicted in Table A3 in the Appendix A. The knowledge about diabetes diet (89.5% correct answers) and diabetic retinopathy/ hypoglycemia (85.1%) was sufficient. The knowledge about diabetes diagnosis & referral, types & self-management and microvascular complications and their screening was insufficient, (30.6% to 57.0% correct answers).
In order to study the association between practice behaviour with knowledge, their overall mean scores were standardized to a scale of 10 with overall mean scores of 5.5 and 4.8 respectively. Practice behaviour was associated with knowledge with an odds ratio of 1.64 and a standardized regression coefficient (beta) of 0.50 with a p-value <0.01. Subsequently, we examined for each pair of questions the association between practice behaviour and knowledge to determine to which extent specific practice behaviour was associated with the knowledge on this topic. In Table 2 the associations with p value below 0.2 are shown. The highest odds ratio (1.99) was observed for the association of microvascular complication screening with the knowledge question on this topic (beta-coefficient of 0.68) with a p-value of 0.09. Nearly the same association was observed for microvascular screening & peripheral neuropathy management with an odds ratio of 1.97 and beta of 0.68 (p= 0.01). The only other pair for which a significant association was observed was for HbA1c testing and diabetes, diagnosis and referral with an odds ratio of only 0.53 and a beta of -0.61 (p=0.04).
We used the mosaic plots to analyze the relationship between correct answers to practice behaviours questions with incorrect knowledge to determine common misconceptions and myths in diabetes care amongst community health workers. There were indeed four such instances where the CHWs answered more than 50% of the correctly answered practice behaviour questions and incorrectly answered knowledge questions. Table 3 depicts these relationships and their frequencies in detail. The mosaic plots can be found in the Appendix A.1.
4. Discussion
The study revealed insufficient practice behaviours and knowledge in ≥ 95% CHWs working in rural areas in India and who are responsible for diabetes screening and management. The identified areas of insufficiency were broadly representative of the core competencies required for effective diabetes management, encompassing diabetes diagnosis and referral, HbA1c testing, diabetes diet, diabetes type and self-management, microvascular complications and their screening, peripheral neuropathy management, and diabetes risk assessment.
Our observations align with existing literature [25,26,27,28,29] documenting incorrect practices among CHWs due to limited or insufficient knowledge. This underscores the need for thorough needs assessments to identify existing knowledge gaps and incorrect practices among CHWs. By addressing these gaps, we can enhance the effectiveness of CHW training programs and ultimately improve diabetes management outcomes.
The summary score of knowledge revealed a stronger association (OR 9.03, p=0.09) with the summary score of practice behaviours compared to associations of knowledge with practice behaviour when each pair of questions was analyzed separately (highest OR 1.99, p=0.09). This observation suggests that while overall knowledge levels tended to positively influence practice behaviours, the relationship was not as evident at the level of specific questions. To further investigate this discrepancy, we employed mosaic plots, which provided insights into potential associations between correct practice behaviours as reported by the respondents and incorrect knowledge. Interestingly, we identified several instances where CHWs reported correct practice behaviours despite possessing incorrect knowledge. This could be attributed to several factors, including prior training, educational differences, or the non-essential nature of specific knowledge for certain practices after adequate training. However, it is crucial to note that even in these cases, incorrect knowledge may hinder the long-term sustainability of the observed correct practice behaviours as it is more likely to push forth incorrect or out-of-date practice behaviours. Thus, focusing solely on either knowledge or behaviour may not yield the desired long-term outcomes. Instead, an integrated, comprehensive approach focusing on both components is essential for effectively equipping CHWs to provide quality diabetes care.
The major strengths of the study were that the questionnaire was developed in close cooperation with the medical staff ultimately responsible for diabetes care as well as using input and feedback from the target group studied. We were therefore able to develop the questionnaire into an accessible tool that could be readable and understandable for all CHWs. In addition, we recruited a relatively large number of participants from multiple rural areas increasing the external validity of our observations. The study also has high generalizability in similar geographies of rural Southeast Asia which bear similarities to our study site like similar diversities of linguistics, education, cultures, practices and socio-demographic factors. Given the time necessary to explain and subsequently fill in the questionnaire, we had to restrict the number of questions for each domain. Moreover, in a few cases, we had to combine two questions into one question, which might have caused difficulty in comprehension for the CHWs and which may have weakened the associations between knowledge and practice behaviour for a specific topic.
Finally, some areas require further exploration, like the correct practice behaviours linked with the incorrect practice behaviours and vice-versa; the barriers and enablers for such relationships also need exploration. The analysis surprisingly discovered that the use of HbA1c testing in daily practice was negatively associated with knowledge of diabetes, diagnosis, and referral: with an odds ratio of 0.53, beta-coefficient of 0.61 and p-value 0.04. This finding, which is currently difficult to explain, needs further exploration in order to improve future training.
5. Conclusions
To conclude, the vast majority of the CHWs involved in diabetes screening and management in rural areas reported inadequate practice behaviour and had insufficient knowledge underlying these behaviours. Defining these gaps in knowledge and practice behaviour is very informative in setting up tailored education programs. However, in several areas, correct practice behaviour was reported by a relatively large number of CHWs despite incorrect answers to the related knowledge questions. Hence, training of CHWs, should not only identify prior knowledge and/or behavior but also their interrelationship to help create a robust and flexible set of practice behaviors that are in line with guidelines on diabetes care, that are continuously changing over time.

Appendix A.1. Mosaic Plots Depicting the Strong Relationship between Correct Practice Behaviour and Incorrect Knowledge
Each mosaic plot consists of four sections. Each plot has the number of participants answering knowledge questions on the X-axis and practice behaviour questions on the Y-axis. In the plot, there are two columns, each divided into two parts. The left column shows the number of participants who answered knowledge questions incorrectly. The right column shows the same for correctly answered knowledge questions. The upper part of each column shows the number of participants who answered practice behaviour questions correctly and the lower part who answered incorrectly. Further, the upper right section shows the number of participants who answered both knowledge and practice behaviour questions correctly, and the upper left section shows the number of participants who answered the practice behaviour questions correctly but the knowledge questions incorrectly. The lower left section shows the number of participants who answered both the knowledge and practice behaviour questions incorrectly. The lower right section shows the number of participants who answered knowledge questions correctly but practice behaviour questions incorrectly.
