0893 Familismo as a Framework for Promoting Adolescent Sleep Health: A Family-Based Behavioral Intervention Pilot

Abstract Introduction Sleep health is influenced by family routines and relationships, yet few interventions have explicitly targeted family systems as a pathway to improving sleep. Rooted in the cultural value of “familismo” — emphasizing family connectedness, support, and collective well-being — the FAMILISMO intervention was developed to promote family-level sleep and nutritional health through culturally grounded parent–adolescent sessions. This study reports implementation and preliminary sleep outcomes from the initial FAMILISMO trial. Methods Fourteen parent–adolescent dyads (adolescents aged 13–17) participated in a six-week telehealth program integrating sleep education, environmental optimization, and collaborative goal-setting around routines and technology use. Pre- and post-intervention assessments included standardized measures of sleep quality (Pittsburgh Sleep Quality Index; PSQI), insomnia severity (Insomnia Severity Index; ISI), daytime sleepiness (Epworth Sleepiness Scale; ESS), and sleep-disturbance symptoms (Sleep Disorders Symptom Check List; SDSCL). Family-context variables were assessed using the Familism Scale (HFS) and Mexican American Cultural Values Scale (MACVS). Results All enrolled dyads completed both pre- and post-intervention assessments, demonstrating successful implementation of the telehealth format. Participants showed significant reductions in insomnia severity, sleep-disturbance symptoms, and daytime sleepiness (all p<.05), along with a nonsignificant trend toward improved overall sleep quality. Specifically, ISI decreased from 7.45 (SD = 5.67) to 5.81 (SD = 4.05), t(30)=2.32, p=0.028, d=0.42; SDSCL decreased from 16.90 (SD = 16.14) to 11.23 (SD = 9.87), t(30)=2.50, p=0.018, d=0.45; and ESS decreased from 5.97 (SD = 3.62) to 4.80 (SD = 3.62), t(29)=2.24, p=0.033, d=0.41. Family-context variables remained stable over time, with a strong baseline correlation between familism and Mexican American cultural values (r=0.526, p<.001). Conclusion FAMILISMO is a culturally responsive, family-based telehealth intervention that can be implemented with Hispanic families. Preliminary analyses indicate that the program significantly reduced insomnia, sleep-disorder symptoms, and daytime sleepiness, with a positive trend toward better overall sleep quality. These findings support continued evaluation of dyadic, culturally grounded approaches to sleep health promotion in Hispanic populations. Support (if any)
