Cognition, Motivation, Symptom, and Functioning Measures
Schizophrenia, Depression
POSITIVE
Cognition was measured using the Penn Computerized Neurocognitive Battery, Measurement and Treatment Research to Improve Cognition in Schizophrenia version. The participants were provided a link to the battery and completed the measures independently. The following self-report measures of motivation and related constructs were completed on the web via REDCap (Research Electronic Data Capture; Vanderbilt University): Motivation and Pleasure Scale (MAPS) Self Report, Motivation State Questionnaire (MSQ), Defeatist Beliefs Scale, Temporal Experience of Pleasure Scale (TEPS), Behavioral Inhibition Scale and Behavioral Activation Scale, Beck Depression Inventory, and University of California Los Angeles Loneliness Scale. Symptoms and functioning were assessed using the following interview-rated measures conducted via videoconference: Quick Scale for the Assessment of Negative Symptoms (QSANS) and Quick Scale for the Assessment of Positive Symptoms (QSAPS), the abbreviated Quality of Life Scale (QLS), and the Role Functioning Scale (RFS). Across all measures, higher scores indicated more of the construct measured. For example, higher Assessors who completed the diagnostic interview and the interview-rated measures of symptoms and functioning had completed a master’s or doctoral degree in psychology or related fields and completed extensive training including observation of videos and practice ratings, observing assessments conducted by senior staff members, mock interviews, and assessment of participants while being observed by a senior staff member (coauthors MF or AC). Participants, PRIME coaches, and assessment staff were blinded to group assignment. The study coordinator was unblinded to enroll and randomize participants, perform weekly check-ins with participants, and provide support while the participants completed their assigned training program.
