However, many of these systems rely on patient data collected by smartphones or other wearable devices to infer patients’ mental status, which raises privacy concerns. Such a value-privacy paradox poses significant challenges to patients’ adoption and use of MMHS; yet, there has been limited understanding of it. OBJECTIVE To address the significant literature gap, this research aims to investigate both the antecedents of patients’ privacy concerns and the effects of privacy concerns on their continuous usage intention with regard to MMHS. METHODS Using a web-based survey, this research collected data from 170 participants with MMHS experience recruited from online mental health communities and a university community. The data analyses used both repeated analysis of variance and partial least squares regression. RESULTS The results showed that data type (P=.003), data stage (P<.001), privacy victimization experience (P=.01), and privacy awareness (P=.08) have positive effects on privacy concerns. Specifically, users report higher privacy concerns for social interaction data (P=.007) and self-reported data (P=.001) than for biometrics data; privacy concerns are higher for data transmission (P=.01) and data sharing (P<.001) than for data collection. Our results also reveal that privacy concerns have an effect on attitude toward privacy protection (P=.001), which in turn affects continuous usage intention with regard to MMHS. CONCLUSIONS This study contributes to the literature by deepening our understanding of the data value-privacy paradox in MMHS research. The findings offer practical guidelines for breaking the paradox through the design of user-centered and privacy-preserving MMHS.

The Brief Resilience Scale (BRS) has extensive psychometric support; however, prior research indicates both a one- and two-factor (i.e., succumbing and resilience) structure. Further, the psychometric properties of the BRS have not been examined among alt-sex community members. As such, the current study examined the BRS factor structure among alt-sex individuals and measurement invariance across demographic groups (i.e., sexual orientation, gender identity, and sexual assault history). Confirmatory factor analyses and multi-groups invariance analyses were conducted. The two-factor BRS model demonstrated better fit to the data. Model fit did not differ by sexual orientation or gender identity. Measurement invariance was observed by lifetime sexual assault history, with higher factor loadings on succumbing items among alt-sex community members with a lifetime history of sexual assault. Our findings support use of the BRS to measure resilience among alt-sex individuals. Succumbing, or weakened resilience, is a salient factor for alt-sex community members who are sexual assault survivors, warranting further attention.

While many behavioral interventions targeting nutrition and physical activity have been developed to promote GWG within the Institute of Medicine guidelines, engagement and results are variable. Technology-mediated interventions can potentially increase the feasibility, acceptability, and reach of interventions, particularly for pregnant women, for whom integration of interventions into daily life may be critical to retention and adherence. Previous reviews highlight GWG self-monitoring as a common intervention component, and emerging work has begun to integrate digital self-monitoring into technology-mediated interventions. With rapid advances in technology-mediated interventions, a focused synthesis of literature examining the role of digital self-monitoring tools in managing GWG is warra...

Through a structured and team-based design, authors participate in a “marathon” of writing, editing, revising, and submitting their publications within a specified period. This active-learning approach is considered a high-impact practice by engaging students in research dissemination through a collaborative project. This study sought to evaluate the feasibility and acceptability of a virtual Paper Chase exercise. We conducted the Paper Chase with six teams led by multidisciplinary faculty (with 24 undergraduate students and four graduate students). All participants were given pre-and post-surveys, with both open- and closed-ended questions. Results indicated that the process increased cooperative and problem-solving components of group work attitudes, increased participants’ confidence in writing skills, increased understanding of research processes and that participants appreciated putting the...

This study used a cost- and -time effective framework to leverage, aggregate, and analyze data from social media. This paper enhances our understanding of diet-related discussions with respect to political orientations in U.S. states. This mixed methods study used computational methods to collect tweets containing “diet” or “#diet” shared in a year, identified tweets posted by U.S. Twitter users, disclosed topics of tweets, and compared democratic, republican, and swing states based on the weight of topics. A qualitative method was employed to code topics. We found 32 unique topics extracted from more than 800,000 tweets, including a wide range of themes, such as diet types and chronic conditions. Based on the comparative analysis of the topic weights, our results revealed a significant difference between democratic, republican, and swing states. T...

To examine the impact of a theory-based lifestyle intervention on gestational weight gain, postpartum weight loss, and related maternal and child outcomes and to examine race differences in these outcomes. A randomized controlled trial (target N=400; 200 intervention, 200 standard care; 200 African American, 200 white). Overweight and obese African American and white women ≤16weeks gestation are recruited from obstetrics and gynecology clinics in South Carolina. Intervention participants receive two in-depth counseling sessions (early pregnancy and postpartum), telephone counseling, behavioral podcasts, and social media support that target weight self-monitoring and increasing physical activity and healthy dietary behavior practices, guided by Social Cognitive Theory. Standard care participants receive monthly mailings...

This study documents the impacts of pandemic-related contextual factors on birth doula care in the San Francisco Bay Area, examines how doulas adapted their services, and explores implications for policy and practice. We employed a contextually bound qualitative case study methodology driven by social action theory and conducted interviews with 15 birth doulas. The pandemic disrupted physical settings, the social environment, communication modalities, contractual arrangements, and organizational level factors. The historical context also amplified awareness of institutionalized racism in birth settings and highlighted birth doulas’ advocacy role. Striking deficits exist in birth doulas’ integration into US healthcare systems; this made their services uniquely vulnerable to the pandemic circumstances. Birth doulas’ value ought to be mor...
