Aims: Many practice guidelines place cognitive-behavioral therapy (CBT) as the gold-standard treatment for psychotic disorders. Our previous meta-analysis on group psychotherapy for schizophrenia (Burlingame et al., under review) employed a strict set of inclusion criteria (e.g., RCT, use of 2 measures, comparison groups, etc.) limiting the number of CBT studies applied to patients presenting on the psychosis spectrum. It found no meta-analytic evidence for group CBT (GCBT) ameliorating psychotic symptoms but only included 5 studies. This meta-analysis will be less restrictive to include more interventions under a broader GCBT umbrella to extend our earlier findings.
Methods: A literature search identified nearly 20 more randomized controlled trials that included in our previous analysis that evaluated some form of GCBT in treating psychosis. Three main outcomes will be assessed: schizophrenia-specific measures of psychotic symptoms, treatment-specific measures assessing treatment aims, and general measures assessing broad functioning.
Results: Preliminary results are still being calculated. Subgroup analyses will include Burlingame et al.'s (under review) CBT categorization and include interventions broadly focused on behavior and cognition, including social skills interventions that also emphasize cognition (viz., Granholm et al., 2005, 2007).
Discussion: Results will be framed in relation to Burlingame et al.'s (under review) meta-analysis. It is likely that the stricter classification of CBT resulted in an attenuation of the effects with a psychosis population. Furthermore, there is a general lack of agreement on what interventions should be labeled CBT (nb., Wampold et al., 1997; Wampold & Imel, 2015).
