AbstractNegative symptoms are a key therapeutic target in promoting functional recovery in early psychosis intervention, but momentary negative symptom manifestations remain understudied in the early stage of illness. We employed an experience-sampling methodology (ESM) to evaluate momentary affective experiences, hedonic capacity for an event recalled, current activities and social interactions, and associated appraisals for 6 consecutive days in 33 clinically-stable early psychosis patients (within 3 years of treatment for first-episode psychosis) and 35 demographically-matched healthy controls. Adjusted multilevel linear-mixed models revealed higher intensity and variability of negative affect in patients than controls, but no group difference in affect instability as well as positive affect intensity and variability. Patients demonstrated no significantly greater anhedonia for event, activity or social interactions relative to controls. Higher preference for company (when alone) and to be alone (when in company) was observed in patients than controls. No significant group difference in pleasantness to be alone or proportion of time being alone. Our results indicate no evidence for blunting of affective experiences, anhedonia (social and non-social) and asociality in early psychosis. Future research complementing ESM with multiple digital phenotyping measures will facilitate more refined negative symptom assessment in the daily life of patients with early psychosis.
