Abstract Background: Tayside children's sleep questionnaire (TCSQ) is a simple tool for screening the Disorders of Initiating and Maintaining Sleep among children aged between one and five years. In this study, we aimed to translate TCSQ into Persian and evaluate the validity and reliability of TCSQ among Persian speakers.Methods: A cross-sectional study was conducted among 311 children aged 1-5 years in Isfahan. After permission, the forward-backward translation method is used to develop the Persian version. Finally, 311 children participated in this survey, and 30 were repeated for a second time. Google Form, SPSS16, and STATA14 were used for data collection, descriptive statics, and factor analysis. BEARS questionnaire is used for convergent validity. Three expert opinions were used for content validity.Results: In this study, 404 mothers of children in Isfahan volunteered to participate in the survey, of which 311 remained. The mean and standard deviation age of their children was 3.47±1.91 years. Cronbach Alpha of the Persian version of TCSQ was 0.76 CI (0.78-0.66). The intra-class correlation coefficient was 0.67 CI (0.60-0.74). The content validity index was 0.88, and three factors (Disturbance, nighttime, parents) with a specific value greater than 0.4 is determined by factor analysis.Conclusions: The current study results indicate that TCSQ has good reliability and validity among Persian speakers.

Background The use of a valid and reliable outcome scoring system is crucial for evaluating the result of different treatment interventions. The aims of this study were to translate and culturally adapt the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scoring system into the Persian language and assess its validity and reliability. Method In total, 57 patients with midfoot injuries were enrolled. Forward-backward translation and cultural adaptation methods were used to develop the Persian version of AOFAS midfoot scoring system. Reliability and internal consistency were assessed using intraclass correlation coefficient (ICC) and Cronbach’s alpha. The discriminant and convergent validities of the scoring system were assessed using the total score of the mental and physical component of SF-36. Results The mean age of the participants was 46.2 ± 16.3 years. The intra-observer reliability of the totals core of the Persian version of AOFAS midfoot scoring system was 0.96 (confidence interval [CI]: 0.92-0.97) and the inter-observer reliability of the scoring system was 0.90 (CI: 0.86-0.95). The Persian version of AOFAS midfoot scoring system had acceptable convergence with physical component scoring system of SF-36 and its subscales (0.57); moreover, it had acceptable discriminant validity with the mental component of SF-36 and its subscales (0.36). Conclusion The Persian version of AOFAS midfoot is a reliable and valid instrument and could be used by Persian language clinicians and researchers. Level of Clinical Evidence: 3

Background. A growing body of research has examined the psychometric properties of popular mindfulness inventories for different population. The present study is aimed at exploring the psychometric properties and factor structure of the Relaxation/Meditation/Mindfulness (RMM) Tracker t Inventory in Iran. Method. This was a cross-sectional and methodological study that conducted in Kerman, southeast Iran. Fifty, 300, and 163 Iranian adult participants were participated in the pilot, exploratory, and confirmatory phase, respectively. Face, content, and structural validities, Cronbach’s alpha, and Omega coefficient were used to validate the Persian scale. Results. The results showed that the “Persian version of RMM t” had acceptable content and face validities. The Principal Axis Factoring (PAF) with Promax Rotation showed that the P-RMM t has 3 scales of “Mindful Love, Thankfulness, and Transcendence,” “Relaxation,” and “Mindful Deepening” which further confirmed with confirmatory factor analysis. The internal consistency of all three scales was acceptable (Cronbach’s alpha coefficients > 80 ). Conclusion. The Persian version of RMM Tracker t seems to be a valid and reliable questionnaire to assess the levels of mindfulness in the Iranian general population.

The aim of this study was to determine the psychometric properties of the Persian version of pregnancy symptoms inventory. A methodological study. This study was conducted on 220 pregnant women. Construct validity was measured by exploratory factor analysis and confirmatory factor analysis. Reliability was measured by intra-class correlation coefficient and internal consistency. Since the items 12 (snoring) and 16 (thrush) failed to obtain the minimum principal axis factoring in exploratory factor analysis, they were removed from the Persian version. Confirmatory factor analysis showed a good fit for the extracted model. Cronbach’s alpha was .94 for the frequency items and .95 for the limitation items. Intra-class correlation coefficient was between .58 and 1 for frequency items and between .73 and 1 for limitation items. The Persian version of pregnancy symptoms inventory was a valid and reliable scale to be used for Iranian pregnant women.

Objective: The worldwide pandemic of coronavirus disease (COVID-19) has caused significant public health burdens and psychological dysfunctions. In this challenging time, adolescents require special care. The Persian version of the Obsession with COVID-19 Scale (OCS) for adolescents was developed to screen for dysfunctional obsession associated with the coronavirus during the global pandemic. The structure and internal consistency of the OCS were established.Design and Measures: Although there are different language versions of the OCS, this is the first study to validate the psychometric properties of the OCS in Iranian adolescents. Seven hundred and nine students (369 girls) participated in the study. Demographic questions and the OCS were administered.Results: The findings provided support for the existence of a unidimensional structure that met the criteria for configural, metric, and full scalar invariance across gender (girls and boys), inhabitancy (urban and rural), and infection experience (infected and non-infected). The OCS is short and highly reliable measurement. However, further research is necessary to establish the validity of the scale in Iranian population.Conclusions: The development of such valid scales is an essential part of both research and practice during times of crisis, like a global pandemic. Diagnosis of pandemic related to obsessive thoughts in adolescents is needed as the COVID-19 pandemic is still ongoing and as experts point out, it can be expected that the effects of the pandemic will be observed in the coming years. The Persian version makes it possible to conduct international comparative research on the anxiety related to the COVID-19 pandemic.
