Aim The aim of this study was to clarify whether improvement of cognitive functioning by cognitive remediation therapy can improve work outcome in schizophrenia and other severe mental illnesses when combined with supported employment. Methods The subjects of this study were persons with severe mental illness diagnosed with schizophrenia, major depression, or bipolar disorder (ICD-10) and cognitive dysfunction who participated in both cognitive remediation using the Thinking Skills for Work program and a supported employment program in a multisite, randomized controlled study. Logistic and multiple linear regression analyses were performed to clarify the influence of cognitive functioning on vocational outcomes, adjusting for demographic and clinical variables. Results Improvement of cognitive functioning with cognitive remediation significantly contributed to the total days employed and total earnings of competitive employment in supported employment service during the study period. Any baseline demographic and clinical variables did not significantly contribute to the work-related outcomes. Conclusion A cognitive remediation program transferring learning skills into the real world is useful to increase the quality of working life in supported employment services for persons with severe mental illness and cognitive dysfunction who want to work competitively.

Devising new methods to improve neurocognitive impairment through cognitive remediation is an important research goal. We developed an original computer programme termed the Japanese Cognitive Rehabilitation Programme for Schizophrenia (JCORES) that provides cognitive practice across a broad range of abilities. The current study examined for the first time whether a cognitive remediation programme, including both computerised cognitive training using JCORES and group intervention such as enhancing meta-cognition and teaching strategies, is more effective than treatment as usual for improving neurocognitive and social functioning. Sixty-two outpatients with schizophrenia were randomised to either a cognitive remediation group or a control group. Participants engaged in two computerised cognitive training sessions and one group meeting per week for 12 weeks. The average number of total sessions attended (computerised cognitive practice + group intervention) was 32.3 (89.7%). The cognitive remediation group showed significantly more improvements in verbal memory, composite score of the Brief Assessment of Cognition in Schizophrenia, Japanese version (BACS-J), and general psychopathology on the Positive and Negative Syndrome Scale (PANSS) than the control group. These findings demonstrate that a cognitive remediation programme is feasible in Japan and is a more effective way to improve neurocognitive functioning and psychiatric symptoms.

Background: In Japan, Job assistance for SMI have been not active. Compared with mental retardation, employment rate of SMI was low. The needs of the effective job assistance for SMI are growing. The purpose of this study was to determine the effectiveness of the combination approach of Cognitive Remediation (CR) and Supported Employment (SE) in clinical outcomes, including cognitive functioning and psychiatric symptoms besides vocational outcomes. Methods: The participants diagnosed with schizophrenia or schizoaffective disorder were assigned to CR+SE group (n=52) and SE group (n=57). CR comprised computer based trainings using COGPACK and group works. SE was individualized vocational support provided by employment specialists. Outcome measures included cognitive functioning, psychiatric symptoms, social functioning, performance of tasks as clinical outcomes, employment rate, duration of employment, and earned wage as vocational outcome. Results: CR+SE group displayed significantly better psychiatric symptoms (F=3.490, pDiscussions: This is the first controlled study to determine the effectiveness of CR on vocational outcomes in Japan. The results showed that CR and SE programs were feasible in Japan and that CR using COGPACK had favorable effects on cognitive functioning, psychiatric symptoms, and social functioning, which is consistent with previous researches.

OBJECTIVE Cognitive impairment is common in schizophrenia, and is associated with poor psychosocial functioning. Previous studies had inconsistently shown improvement in cognitive functions with cognitive remediation therapy. This study examined whether cognitive remediation is effective in improving both cognitive and social functions in schizophrenia in outpatient settings that provide learning-based psychiatric rehabilitation. This study is the first randomized controlled trial of cognitive remediation in Japan. METHOD Study participants were individuals with schizophrenia from 6 outpatient psychiatric medical facilities who were randomly assigned either a cognitive remediation program or treatment as usual. The cognitive remediation intervention includes Cognitive training using computer software (CogPack; Japanese version) administered twice a week and a weekly group over 12 weeks and was based on the Thinking Skills for Work program. Most study participants were attending day treatment services where social skills training, psychoeducation for knowledge about schizophrenia, group activities such as recreation and sport, and other psychosocial treatment were offered. Cognitive and social functioning were assessed using the Brief Assessment of Cognition in Schizophrenia (BACS) and Life Assessment Scale for Mentally Ill (LASMI) at pre- and postintervention. RESULTS Of the 60 people with schizophrenia enrolled, 29 were allocated to the cognitive remediation group and 31 were allocated to the treatment as usual group. Processing speed, executive function, and the composite score of the BACS showed significantly greater improvement for the cognitive remediation group than the treatment as usual group. In addition, there was significant improvement in interpersonal relationships and work skills on the LASMI for the cognitive remediation group compared with the treatment as usual group. Changes from pretreatment to posttreatment in verbal fluency and interpersonal relationships were significantly correlated, as well as changes in attention and work skills. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE The present findings showed that providing cognitive remediation on addition to psychiatric rehabilitation contributed to greater improvement in both cognitive and social functioning than psychiatric rehabilitation alone. Cognitive remediation may enhance the efficacy of psychiatric rehabilitation improving social functioning. (PsycINFO Database Record

Methods to improve neurocognitive impairments are of important research interest. This study sought to examine the synergistic effects of neurocognitive rehabilitation and antipsychotics for schizophrenia.Subjects were 43 patients diagnosed with schizophrenia or schizoaffective disorder in a randomized trial of the effects of neurocognitive rehabilitation or a quasi-randomized experimental trial of supported employment with neurocognitive rehabilitation. We compared the effects of risperidone and aripiprazole in neurocognitive rehabilitation for schizophrenia. Subjects were divided into the following groups: (i) the control-risperidone group (CR group) (n = 13); (ii) the rehabilitation-risperidone group (RR group) (n = 9); (iii) the control-aripiprazole group (CA group) (n = 10); and (iv) the rehabilitation-aripiprazole group (RA group) (n = 11). Subjects in the rehabilitation group were engaged in computer-based cognitive exercises (24 sessions) with bridging group (12 sessions) over 12 weeks. Psychiatric symptoms, neurocognitive functioning and social functioning assessments were evaluated at baseline and at 12 weeks.A two-way anova with neurocognitive rehabilitation and antipsychotic medication as factors revealed a significant interaction effect on motor speed. Working memory and motor speed significantly improved in the RA group compared with the CA group. We found no significant improvements between the CR group and the RR group.A synergistic effect of neurocognitive rehabilitation and aripiprazole was observed as improvement of motor speed. In patients treated with aripiprazole, neurocognitive rehabilitation appeared to improve working memory and motor speed. Further studies of synergistic effects of neurocognitive rehabilitation and antipsychotic medication are necessary to verify these findings.
