Prospective Relationships Between Motivation and Functioning in Recovery After a First Episode of Schizophrenia.

ABSTRACT: Diminished motivation is associated with robust impairment in psychosocial functioning in schizophrenia (SZ). Little is known about the reciprocal relationships between motivation and functioning, particularly following a first episode of psychosis. We tested bidirectional associations between motivation and social and occupational functioning in the year following a first episode of SZ spectrum disorder among patients in the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study. Four hundred four individuals (aged 15-40) who presented with a first episode of SZ spectrum disorder (eg, SZ, schizoaffective or schizophreniform disorder, psychotic disorder not otherwise specified) completed assessments of work and school functioning, social functioning, and motivation at 6- and 12-month follow-up, controlling for assessments at study entry. Controlling for cognition, and psychotic and depressive symptoms measured at each time point, motivation at 6 months was associated with work and school participation at 12 months, but work and school participation at 6 months was not associated with motivation at 12 months. Conversely, social functioning at 6 months was associated with motivation at 12 months, but motivation at 6 months was not associated with social functioning at 12 months. Findings suggest that motivation is associated with later occupational, but not social, functioning in the first year following an initial episode of psychosis. Social functioning, on the other hand, is associated with later motivation. Future intervention trials focused on improving occupational functioning in this population may benefit from targeting patient motivation directly (eg, through motivational interviewing), or indirectly by improving relationships and support networks.

Project description:BackgroundThough olfactory deficits are well-documented in schizophrenia, fewer studies have examined olfactory performance profiles across the psychosis spectrum. The current study examined odor identification, discrimination, and detection threshold performance in first-episode psychosis (FEP) patients diagnosed with schizophrenia, schizoaffective disorder, bipolar disorder with psychotic features, major depression with psychotic features, and other psychotic conditions.MethodFEP patients (n = 97) and healthy adults (n = 98) completed birhinal assessments of odor identification, discrimination, and detection threshold sensitivity for lyral and citralva. Participants also completed measures of anticipatory pleasure, anhedonia, and empathy. Differences in olfactory performances were assessed between FEP patients and controls and within FEP subgroups. Sex-stratified post hoc analyses were employed for a complete analysis of sex differences. Relationships between self-report measures and olfactory scores were also examined.ResultsIndividuals with psychosis had poorer scores across all olfactory measures when compared to the control group. Within the psychosis cohort, patients with schizophrenia-associated psychosis had poorer odor identification, discrimination, and citralva detection threshold scores relative to controls. In schizophrenia patients, greater olfactory disturbance was associated with increased negative symptomatology, greater self-reported anhedonia, and lower self-reported anticipatory pleasure. Patients with mood-associated psychosis performed comparable to controls though men and women in this cohort showed differential olfactory profiles.ConclusionsThese findings indicate that olfactory deficits extend beyond measures of odor identification in FEP with greater deficits observed in schizophrenia-related subgroups of psychosis. Studies examining whether greater olfactory dysfunction confers greater risk for developing schizophrenia relative to other forms of psychosis are warranted.
