Environmental resource reductions predict greater severity of negative symptoms in schizophrenia.

ABSTRACT: No pharmacological or psychosocial interventions effectively treat negative symptoms in schizophrenia (SZ), despite the identification of biological and psychological mechanistic targets. Limited treatment progress may result from failure to account for non-person-level environmental factors that present barriers to performing recreational, social, and goal-directed activities. The bioecosystem model of negative symptoms proposes that four interactive ecosystems (i.e. microsystem, mesosystem, exosystem, and macrosystem) influence person-level factors (e.g., dysfunctional beliefs, glutamate, cortico-striatal functioning) to initiate and maintain negative symptoms. The current study tested this hypothesis by examining whether indirect environmental factors (e.g., access to resources for perf
