improving negative symptoms & community engagement in veterans with schizophrenia

Conditions: Schizophrenia; Serious Mental Illness

Summary: the goal of this project is to evaluate an innovative psychosocial intervention package that will incorporate evidence-based treatment strategies to target the affective-motivational deficits, negative expectancies, and behavioral skills deficits that are central to the maintenance of negative symptoms. the intervention - called encore (engaging in community roles and experiences) - will include strategies aimed at teaching veterans with schizophrenia and negative symptoms ways to (1) overcome deficits in anticipatory pleasure, (2) increase intrinsic motivation for goal-directed activities, (3) reduce expectancies for failure, and (4) perform skillfully in new social situations, all of which can impact implementation of new skills and behaviors. rather than develop a new set of intervention strategies, the investigators will include within encore evidence-based strategies for these treatment domains. in addition, the investigators will collect qualitative information both from veterans concerning their perceptions of the strengths, weaknesses, and barriers to participation in encore, as well as from a sample of mental health providers who work with veterans with schizophrenia and negative symptoms, in order to inform a larger scale implementation trial should encore prove effective here.
