Heterogeneity in the three-year course of XXXX among older adults.

@entity1 @entity308
OBJECTIVE: The objective of this research was to identify distinct trajectories of recovery in older @entity308 @entity1 in order to identify optimal samples and points for interventions. METHODS: The sample was 368 @entity1 ages 60   years and older diagnosed with @entity308 and enrolled in a naturalistic treatment study and followed for up to 3   years. RESULTS: A model with four trajectory classes fit the data best: a quick recovery class (43%), a persistent moderate symptom class (27%), a persistent high symptom class (15%), and a slow recovery class (15%). Compared with @entity1 in the quick recovery class, @entity1 in the persistent moderate symptom class had more instrumental activities of daily living/mobility limitations and lower levels of subjective social support. @entity1 in the persistent high symptom class had higher levels of perceived stress and lower levels of social support compared with those with a quick recovery. @entity1 in the slow recovery class had a younger age of onset compared with those in the quick recovery group. In multinomial logistic regression, levels of perceived stress and social support at baseline significantly differed across classes controlling for demographic and health variables. CONCLUSIONS: Older @entity1 diagnosed with @entity308 can have varying patterns of response to treatment. Interventions targeting those @entity1 with higher levels of perceived stress and lower levels of subjective social support at the time of the index episode may lead to more favorable long-term trajectories.
