Researchers have proposed using digital technologies to index daily biobehavioral functioning, yet there is a dearth of research examining how wearable metrics are associated with mental health. METHODS: We preregistered analyses using the Adolescent Brain Cognitive Development Study dataset using wearable data collection in 5,686 adolescents (123,862 person-days or 2,972,688 person-hours) to determine whether wearable indices of resting heart rate (RHR), step count, and sleep duration and variability in these measures were cross-sectionally associated with internalizing symptomatology. All models were also run controlling for age, sex, body mass index, socioeconomic status, and race. We then performed prospective analyses on a subset of this sample (n?=?143) across 25?months that had Fitbit data available at baseline and follow-up in order to explore directionality of effects. RESULTS: Cross-sectional analyses revealed a small, yet significant, effect size (R(2) ?=?.053) that higher RHR, lower step count and step count variability, and greater variability in sleep duration were associated with greater internalizing symptoms. Cross-lagged panel model analysis revealed that there were no prospective associations between wearable variables and internalizing symptoms (partial R(2) ?=?.026), but greater internalizing symptoms and higher RHR predicted lower step count 25?months later (partial R(2) ?=?.010), while higher RHR also predicted lower step count variability 25?months later (partial R(2) ?=?.008). CONCLUSIONS: Findings indicate that wearable indices concurrently associate with internalizing symptoms during early adolescence, while a larger sample size is likely required to accurately assess prospective or directional effects between wearable indices and mental health. Future research should capitalize on the temporal resolution provided by wearable devices to determine the intensive longitudinal relations between biobehavioral risk factors and acute changes in mental health.

Does higher-than-usual stress predict nonsuicidal self-injury? Evidence from two prospective studies in adolescent and emerging adult females / A. B. MILLER in Journal of Child Psychology and Psychiatry, 60-10 (October 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-10 (October 2019) . - p.1076-1084 Titre : Does higher-than-usual stress predict nonsuicidal self-injury? Evidence from two prospective studies in adolescent and emerging adult females Type de document : Texte imprimé et/ou numérique Auteurs : A. B. MILLER, Auteur ; T. EISENLOHR-MOUL, Auteur ; C. R. GLENN, Auteur ; B. J. TURNER, Auteur ; Alexander L. CHAPMAN, Auteur ; M. K. NOCK, Auteur ; M. J. PRINSTEIN, Auteur Article en page(s) : p.1076-1084 Langues : Anglais (eng) Mots-clés : Nonsuicidal self-injury  stress  within-person designs Index. décimale : PER Périodiques Résumé : BACKGROUND: Nonsuicidal self-injury (NSSI) is highly prevalent among adolescent and emerging adult females. Most studies examining the relationship between stress and NSSI largely have relied on aggregate self-report measures of stress and between-person models. Using data from two prospective samples, this manuscript tests the hypothesis that within-person models of NSSI provide better clinical markers of risk for NSSI than between-person models of NSSI. METHODS: Two samples (Sample 1: 220 high-risk girls, M age = 14.68, SD = 1.36, baseline assessment and 3-month follow-ups for 18 months; Sample 2: 40 emerging adult females with a history of NSSI, M age = 21.55, SD = 2.14, 14 days with daily retrospective reports) were followed prospectively and completed validated measures of stress and NSSI. Models were adjusted for age and depression. RESULTS: In Sample 1, a within-person model demonstrated that higher-than-usual (but not average) stress levels predicted NSSI within the same 3-month wave. In Sample 2, results from a within-person model with daily diary assessment data showed that higher-than-usual stress (but not average daily stress) predicted same-day NSSI. CONCLUSIONS: Together, our results suggest that higher-than-usual stress, relative to one's typical stress level, but not average stress levels, signals times of enhanced risk for NSSI. These results highlight the clinical utility of repeated assessments of stress.
