Abstract
The current study examined the feasibility and acceptability of an integrated Cognitive-Behavioral Social Skills Training and Compensatory Cognitive Training (CBSST-CCT) intervention compared with Goal-Focused Supportive Contact (SC) in a pilot randomized controlled trial for people with schizophrenia with high negative symptom severity. The sample included 55 participants from five community settings; masters-level study clinicians delivered interventions on-site. Participants completed assessments of cognitive, functional, and psychiatric symptoms at baseline, mid-treatment, post-treatment (12.5 weeks), and 6-month follow-up. Enrollment goals were not initially met, necessitating the addition of a fifth site; however, all groups and assessments were completed on-site. Study procedures were acceptable, as evidenced by 100% enrollment and completion of baseline assessments following informed consent; however, over 1/3rd of participants dropped out. No modifications were necessary to the intervention procedures and CBSST-CCT fidelity ratings were acceptable. The intervention was deemed acceptable among participants who attended ≥1 session, as evidenced by similar attendance rates in CBSST-CCT compared to SC. Among CBSST-CCT participants, lower positive symptoms were significantly associated with better attendance. Overall, we found mixed evidence for the feasibility and acceptability of the CBSST-CCT protocol in people with schizophrenia with high negative symptoms. Challenges are highlighted and recommendations for future investigations are provided.
