Fundamental o fútil? Relations between multiple familism dimensions and adolescent sleep in a Hispanic sample

The cultural value of familism describes prioritizing family over the individual. Previous evidence supports relations between familism and health behaviors, including sleep. Using data from the Adolescent Brain Cognitive Development Study, this investigation explored associations of parent and adolescent familism and adolescent sleep. The sample included 438 Latino/a parent-adolescent dyads, with youth averaging 11.87 (SD = 0.67) years old (assigned female at birth: 49.78%) and parents averaging 40.51 (SD = 6.50) years old (female: 90.38%) with a majority identifying as Mexican or Mexican American (parents: 53.83%; youth: 54.51%). Most adolescents were born in the United States or its territories (94.28%). Parents and adolescents independently reported on multiple dimensions of familism, including familism support, familism obligation, and familism referent, which were combined to create an overall familism score. Adolescents wore Fitbit devices that measured objective parameters of sleep including minutes, efficiency, wake after sleep onset, latency, midpoint, and variability in minutes and midpoint. Multiple regression models were fit to determine associations of parent and adolescent familism dimensions with adolescent sleep. Youth obligation and parent support familism were related to more ideal sleep, while youth referent and parent obligation familism were related to less ideal sleep. While some dimensions of familism may pose a risk for poor sleep, others support ideal sleep and should be emphasized within the parent-adolescent relationship. As practitioners and clinicians incorporate cultural sensitivity into their practices and recommendations and families cultivate a supportive environment through familism values, Latino/a youth will be more likely to experience optimal sleep outcomes.
