Abstract | © 2020 Elsevier B.V. Background: Developed based on the Clinical Assessment Interview for Negative Symptoms (CAINS), the Motivation and Pleasure Scale-Self Report (MAP-SR) was designed to address the conceptual and psychometric limitations of other instruments assessing negative symptoms. We sought to validate and extend the applicability of the MAP-SR in the Chinese context across the schizophrenia spectrum. Methods: Three samples, including college students, individuals with social anhedonia and patients with schizophrenia, were recruited. Test-retest reliability, internal consistency, factor structure, and convergent/discriminant validity of the MAP-SR were examined. The group differences between the three participant groups were examined. Results: A four-factor structure of the MAP-SR was found consistently in all three groups of participants. The scale showed convergent/discriminant validity in patients with schizophrenia and individuals with social anhedonia, along with good reliability found in schizophrenia patients. The MAP-SR was also able to distinguish individuals with SocAnh and patients with SZ from matched controls. Conclusions: The MAP-SR is a valid and reliable instrument in assessing negative symptoms in individuals along the schizophrenia spectrum. |
