Motivational interviewing to enhance psychosocial treatment attendance in people with SMI.

Background: While there is increasing support for the efficacy of psychosocial interventions for people with SMI, the real-world effectiveness of such treatments is diminished by lack of motivation for treatment, leading to poor treatment engagement/dropout. We sought to evaluate the efficacy of motivational interviewing (MI) in improving attendance in a full course of cognitive training, examine motivation level as a potential mechanism of action, and examine variables associated with initial engagement in the training.

Methods: One hundred fourteen participants with SMI were randomized to MI or sham control interview (CI), both of which were followed by a 4-month active phase during which participants could attend up to 50 unpaid cognitive training sessions.

Psychometrics of social cognitive measures for psychosis treatment research.

Social cognition represents an important treatment target, closely linked to everyday social function. While a number of social cognitive interventions have recently been developed, measures used to evaluate these treatments are only beginning to receive psychometric scrutiny. Study goals were to replicate recently-published psychometrics for several social cognitive measures, and to provide information for additional social cognitive measures not included in recent reports.
