  • Uncovering childcare struggles through topic modeling. Journal of family psychology : JFP : journal of the Division of Family Psychology of the American Psychological Association (Division 43) Mazzaferro, M. M., Sharma, P., Liu, S., Fisher, P. 2026

    Abstract

    Challenges with accessing reliable childcare are a main source of distress for many families with young children. Research has documented the detrimental effects of lack of access to stable and reliable care on caregivers and children, but little is known about which childcare-related challenges and impacts caregivers themselves perceive as most central. We bridge this gap by leveraging biterm topic modeling, a natural language processing technique, to analyze large-scale open-ended survey data, identify common themes brought up by parents when talking about childcare, and examine covariation with family characteristics. A six-topic solution was selected, clustered around two metatopics: access barriers and precarity experiences and psychosocial impacts of childcare challenges. Family characteristics, including child disability, identifying as female, identifying as Black, and having any higher education, were credibly associated with the likelihood of topic emergence in Bayesian regression models, with evidence varying in strength. Future work should focus on accurately measuring different dimensions of childcare challenges, as well as gauging causal and temporal relations between such challenges, family characteristics, and family outcomes. Policy and decision makers may use these and similar data to infer families' priorities when it comes to childcare. (PsycInfo Database Record (c) 2026 APA, all rights reserved).

  • Rapid, Tailored Dietary and Health Education Through A Social Media Chatbot Microintervention: Development and Usability Study With Practical Recommendations. JMIR formative research Ali, S.

    Abstract

    There is an urgent need to innovate methods of health education, which can often be resource- and time-intensive. Microinterventions have shown promise as a platform for rapid, tailored resource dissemination yet have been underexplored as a method of standardized health or dietary education; social media chatbots display unique potential as a modality for accessible, efficient, and affordable educational microinterventions.This study aims to provide public health professionals with practical recommendations on the use of social media chatbots for health education by (1) documenting the development of a novel social media chatbot intervention aimed at improving dietary attitudes and self-efficacy among South Asian American young adults and (2) describing the applied experiences of implementing the chatbot, along with user experience and engagement data.In 2023, the "Roti" chatbot was developed on Facebook and Instagram to administer a 4-lesson tailored dietary health curriculum, informed by formative research and the Theory of Planned Behavior, to 18- to 29-year-old South Asian American participants (recruited through social media from across the United States). Each lesson (10-15 minutes) consisted of 40-50 prescripted interactive texts with the chatbot (including multiple-choice and open-response questions). A preintervention survey determined which lesson(s) were suggested to participants based on their unique needs, followed by a postintervention survey informed by the Theory of Planned Behavior to assess changes in attitudes, self-efficacy, and user experiences (User Experience Questionnaire). This study uses a cross-sectional design to examine postintervention user experiences, engagement, challenges encountered, and solutions developed during the chatbot implementation.Data from 168 participants of the intervention (n=92, 54.8% Facebook; n=76, 45.2% Instagram) were analyzed (mean age 24.5, SD 3.1 years; n=129, 76.8% female). Participants completed an average of 2.6 lessons (13.9 minutes per lesson) and answered an average of 75% of questions asked by the chatbot. Most reported a positive chatbot experience (User Experience Questionnaire: 1.34; 81/116, 69.8% positive), with pragmatic quality (ease of use) being higher than hedonic quality (how interesting it felt; 88/116, 75.9% vs 64/116, 55.2% positive evaluation); younger participants reported greater hedonic quality (P=.04). On a scale out of 10 (highest agreement), participants reported that the chatbot was relevant (8.53), that they learned something new (8.24), and that the chatbot was helpful (8.28). Qualitative data revealed an appreciation for the cheerful, interactive messaging of the chatbot and outlined areas of improvement for the length, timing, and scope of text content. Quick replies, checkpoints, online forums, and self-administered troubleshooting were some solutions developed to meet the challenges experienced.The implementation of a standardized, tailored health education curriculum through an interactive social media chatbot displayed strong feasibility. Lessons learned from challenges encountered and user input provide a tangible roadmap for future exploration of such chatbots for accessible, engaging health interventions.

  • The influence of routine and leisure family activities on the ability of young Asian Americans to maintain a healthy lifestyle: findings from a nationwide survey. Journal of behavioral medicine Ali, S. H., Rouf, R., Mohsin, F. M., Meltzer, G., Sharma, P., DiClemente, R. J. 2022; 45 (6): 962-974

    Abstract

    Family is uniquely influential in the health of young Asian Americans (AAs), yet little is known on the impact of specific shared family activities. This study explores different types and frequencies of AA young adult shared family activities on perceived familial influence on the ability to maintain a healthy lifestyle (diet, physical activity, sleep, social relationships, stress, and risky substances). A nationwide sample of 18-35-year-old AAs was surveyed in March 2021 on a list of 30 shared family activities with mothers, fathers, siblings, or extended family. Overall, 984 unique family relationships reported by 616 young AAs were analyzed. Confirmatory factor analysis synthesized a reliable two-factor (routine, leisure activities) 10-item Shared Activities with Family (SAF) scale. Mothers were most influential (mean 3.25, SD = 1.14), although shared activities among South Asians or with extended family were most associated with changes in perceived influence. Routine shared activities were more strongly associated with perceived influence on sleep, diet, and risky substances, while leisure shared activities were more associated with influence on developing healthy social relationships. Family-based, dyadic interventions for young AAs may incorporate shared activities (both routine and leisure) to promote healthy behaviors, although further research to explore mechanisms and directionality of influence is needed to inform action.
