Using a pattern‐based approach, worry was explored in relation to military youths' developmental and contextual characteristics, and pivotal outcomes (depressive symptoms, self‐efficacy, well‐being, coping styles, academic performance and deployment adjustment). Data were collected from parents and adolescents, age 11 to 18, living in the USA (n = 273 families). Variations in individual characteristics (age and gender), military family factors (rank, recent deployment, parents' resilient coping abilities) and family relational characteristics (parents' marital status, warm parenting, marital quality) were related to heterogeneous worry typologies. Depressive symptoms, self‐efficacy and well‐being, varied across the worry typologies. Implications are drawn from these findings for identifying potential interventions that can be accessed to modify these worry patterns and limit their harmful effects.
