RESUMO
BACKGROUND: Goal setting and tracking are well established behavior change techniques. Little is known about the extent to which commercially available mobile apps are designed to guide parents in using these strategies, their evidence base, and their quality. OBJECTIVE: This study aims to review commercially available apps that target parents in relation to setting and tracking behavioral goals for their children. The objectives were to classify the apps' general characteristics, features, evidence base, and target behaviors and assess app quality overall and separately for apps that target health-related behaviors (HRBs) and apps without a health-related behavior (WHRB). METHODS: Apps were identified using keyword searches in the Apple App Store and Google Play in the United States. Apps were included if their primary purpose was to assist with setting goals, tracking goals, tracking behaviors, or giving feedback pertaining to goals for children by parents. App characteristics and common features were documented and summarized. Two reviewers assessed app quality using the Mobile App Rating Scale (MARS). Descriptive statistics summarized the MARS total score, 4 quality subscales, and 6 app-specific items that reflect the perceived impact of the app on goal setting and tracking, overall and with subgroup analysis for HRB and WHRB apps. RESULTS: Of the 21 apps identified, 16 (76%) met the review criteria. Overall, 9 apps defined and targeted the following HRBs: nutrition and mealtime (6/16, 38%), physical activity and screen time (5/16, 31%), sleep (7/16, 44%), and personal hygiene (6/16, 38%). Three apps targeted specific age groups (2 apps were for children aged 6-13 years and 1 app was for children aged ≥4 years). None of the apps provided tailored assessments or guidance for goal setting. None of the apps indicated that they were intended for the involvement of a health professional or had been tested for efficacy. The MARS total score indicated moderate app quality overall (mean 3.42, SD 0.49) and ranged from 2.5 to 4.2 out of 5 points. The Habitz app ranked highest on the MARS total score among HRB apps (score=4.2), whereas Thumsters ranked highest (score=3.9) among the WHRB apps. Subgroup analysis revealed a pattern of higher quality ratings in the HRB group than the WHRB group, including the mean MARS total score (mean 3.67, SD 0.34 vs mean 3.09, SD 0.46; P=.02); the engagement and information subscales; and the app-specific items about perceived impact on knowledge, attitudes, and behavior change. CONCLUSIONS: Several high-quality commercially available apps target parents to facilitate goal setting and tracking for child behavior change related to both health and nonhealth behaviors. However, the apps lack evidence of efficacy. Future research should address this gap, particularly targeting parents of young children, and consider individually tailored guided goal setting and involvement of health professionals.
RESUMO
OBJECTIVE: Retention of participants has been an issue in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). It has been suggested that the perceived value of WIC may affect whether participants remain in the programme. The present study aimed to explore this phenomenon. DESIGN: Using a constructivist approach, thirty-one individual in-depth interviews were conducted. Transcripts were analysed using constant comparative analysis. Social, cultural and environmental factors that contribute to the value of WIC were explored as the phenomenon of interest. SETTING: Eight WIC clinics across the State of Illinois, USA.ParticipantsThirty-one caregivers of children enrolled in WIC for at least 6 months. RESULTS: Several factors influenced perceived value of WIC at the interpersonal (level of social support), clinic (value of WIC services v. programme administration issues), vendor (shopping difficulties), community and systems levels (other programme use, stigma and restrictions on food choice). Other themes existed along continua, which overlapped several levels (continuum of perceived need and perceived value of infant formula). CONCLUSIONS: Many caregivers value WIC, especially before their child turns 1 year old. Improvements are needed at the clinic, during shopping and within the food packages themselves in order to increase perceived value of WIC.
