About

Objective: To determine the efficacy of computer-assisted cognitive remediation (CACR) in patients with chronic schizophrenia in the community settings.

Study Design: Single-blinded prospective, pre-test/post-test randomized controlled trial (RCT) will be conducted in 2 groups of participants that receiving training in community settings. Treatment groups will attend individualized CACR programme using CogniPlus® while control group will continue attend conventional treatment as usual (TAU). Assessment on the means difference in assessing functions will be done after the study.

Samples: 80 patients with stable and chronic schizophrenia will be recruited from the community, using a sampling frame of selected diagnosis and homogeneity.

Expected Findings: Find out the training effects of selected CACR on EF and daily functioning in patients with schizophrenia.

Full description

Schizophrenia is one of the most serious and disabling mental disorders. Prevalence of schizophrenia is about 1% worldwide. The related dysfunctions have great impact and burden to the concerned person and to the society. With increasing use of CR programmes in helping the patients to resume their capability in community living, the clinical outcome was not fully established especially on specific cognitive domains such as executive function (EF). The present study aims at evaluating the efficacy of CACR on developing EF and improving daily functioning. The result will provide information for therapists' future clinical decisions for patients' best reintegration into the societies. This also helps decrease the burden of family, society in the long run.
