title: Patterns of functional impairment and their change among youth served in systems of care: an application of latent transition analysis.
abstract: This study describes patterns of youth functioning at intake and 6 months into services in systems of care and change in functioning profiles. Participants included 2,826 males and 1,335 females aged 5 to 18 at intake. Functional impairment was assessed at intake and 6 months. Latent class analysis was used to classify youth based on their functional impairment profiles, and latent class transition analysis was used to examine the conditional probabilities of transitions in class membership between intake and 6 months. Males and females enter services with distinct patterns of functional impairment. The majority of youth remained in their respective profiles. Transitions tended to be from a higher to a lower impairment class. Importantly, a small group of males and females transitioned from a low to a higher impairment class. Providers should note that gender differences existed in the nature of change in class membership over time.
