| الوصف: | Negative symptoms such as anhedonia are associated with psychosis risk and poorer outcomes. The Prodromal Questionnaire (PQ) is a self-report questionnaire used to screen for psychosis spectrum symptoms. However, the convergent and divergent validity and underlying factor structure of the PQ–negative symptom subscale (PQ-N) have yet to be examined. Undergraduates ( N = 1,556) completed the PQ, Temporal Experience of Pleasure Scale, and measures assessing anxiety, depression, and motivation. An exploratory factor analysis conducted on the PQ-N yielded a two-factor solution, reflecting subdimensions of social expression and dissociative–depressive experiences, contrary to previous research examining the factor structure of negative symptoms. Associations between the PQ-N, its two factors, and measures of negative symptoms and other psychopathology were examined. Results indicated that the PQ-N and its factors were more strongly correlated with measures of depression and anxiety than with measures of negative symptoms relating to motivation and pleasure, suggesting poor convergent and divergent validity. |
