Problem solving therapy (PST) shows insufficient evidence for schizophrenia treatment. More high-quality trials are needed to confirm its benefits for patients with schizophrenia.

Area of Science:

  • Psychiatry
  • Clinical Psychology

Background:

  • Schizophrenia symptoms cause significant disability and are worsened by environmental stress.
  • Impaired problem-solving skills in schizophrenia affect functioning and quality of life.
  • Problem solving therapy (PST) is a developed intervention to enhance these skills.

Purpose of the Study:

  • To review the effectiveness of problem solving therapy (PST) compared to other therapies or routine care for schizophrenia patients.

Main Methods:

  • Searched Cochrane Schizophrenia Group's Register (September 2006) and inspected references.
  • Included clinical randomized trials comparing PST with comparable therapies or routine care.
  • Extracted data independently, using random effects models for dichotomous and continuous data.

Main Results:

  • Included three small trials (n=52) comparing PST to routine care, coping skills training, or non-specific interaction.
  • Inadequate data reporting limited analysis; meta-analysis was not possible.
  • No significant differences found between groups for hospital admission, mental state, behavior, social skills, or early study withdrawal.

Conclusions:

  • Insufficient evidence exists to confirm or refute the benefits of PST for schizophrenia.
  • Concerns include small participant numbers and poor reporting of methods and results.
  • Further adequately powered trials with robust reporting and meaningful outcomes are necessary.
