Practitioner research that utilizes single‐system designs and replication studies has been promoted as a means to develop psychosocial interventions of demonstrated effectiveness. At the same time, there has been relatively little practitioner publication of single‐system studies. The purpose of this study was to evaluate the effectiveness of cognitive‐behavioural interventions in the treatment of schizophrenia. The study used a single‐system multiple baseline design across seven subjects to evaluate change in clinical outcomes. The AB design included a (A) baseline phase and (B) cognitive‐behavioural intervention phase. Standardized measures of psychosocial functioning, severity of symptoms and attainment of treatment goals were used to assess change over the course of three years treatment. A pre‐test/post‐test design was used to measure achievement of treatment goals. All seven clients made statistically significant improvement in psychosocial functioning when the baseline mean was compared to the intervention mean. The average effect size for the seven cases was 2.96. All seven clients made a statistically significant reduction in severity of psychiatric symptoms when the baseline mean was compared to the intervention mean. The average effect size for the seven cases was −2.19. All seven clients exceeded the expected level of attainment of treatment goals. The pre‐test average goal attainment score for the seven cases was 20.65 (sd = .55). The average post‐test score was 71 (sd = 8). Directions for future research and the applicability of single‐system designs for the practitioner researcher evaluation of mental health practice are discussed.
