Abstract

Background and objectives The treatment of negative symptoms in schizophrenia is a major challenge for mental health care. One randomized controlled trial found that cognitive therapy for low-functioning patients reduced avolition and improved functioning, using an average of 50.5 treatment sessions over the course of 18 months. The aim of our current pilot study was to evaluate whether 20 sessions of Cognitive Behavioral Therapy for negative symptoms (CBT-n) would reduce negative symptoms within 6 months. Also, we wanted to test the cognitive model of negative symptoms by analyzing whether a reduction in dysfunctional beliefs mediated the effects on negative symptoms.Method In an open trial 21 adult outpatients with a schizophrenia spectrum disorder with negative symptoms received an average of 17.5 sessions of CBT-n. At baseline and end-of-treatment, we assessed negative symptoms (PANSS) and dysfunctional beliefs about cognitive abilities, performance, emotional experience, and social exclusion. Bootstrap analysis tested mediation.Results The dropout rate was 14% (three participants). Intention-to-treat analyses showed a within group effect size of 1.26 on negative symptoms (t = 6.16, | Sig = 0.000). Bootstrap analysis showed that dysfunctional beliefs partially mediated the change.Limitations The uncontrolled design induced efficacy biases. Also, the sample was relatively small, and there were no follow-up assessments.Conclusions CBT-n may be effective in reducing negative symptoms. Also, patients reported fewer dysfunctional beliefs about their cognitive abilities, performance, emotional experience, and social exclusion, and this reduction partially mediated the change in negative symptoms. The reductions were clinically important. However, larger and controlled trials are needed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A single group design can still contribute to an understanding of mediation processes.

    “Nevertheless, as Maric argues, a single group design can still contribute to an understanding of mediation processes, and this is evidenced by several recent investigations of mediation in single treatment groups. 28, 47, 57”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
