Objectives:The aim of this study was to investigate whether vocational rehabilitation can bring about improvement in the symptomatic domain, general functional status, and the cognitive abilities of the mentally disabled.
Methods:Twelve mentally disabled persons performed document scanning and adjustments of scanned images as vocational activity. Symptomatic (8-item Korean-Positive and Negative Syndrome Scale, Clincal Global Impression-Severity, Beck Depression Index, Scale to Assess Unawareness of Mental Disorder), functional (Korean-Global Assessment of Function, Life Satisfaction Self-Rating Scale, Korean-Liverpool University Neuroleptic Side Effect Rating Scale), and cognitive (Korean-Wechsler Adult Intelligence Scale, Verbal Fluency Test, Wechsler Memory Scale, Stroop Test and Trail Making Test) domain were assessed, at baseline and after 5 months of the vocational activity.
Results:Verbal memory, executive function, working memory and attention improved significantly. There were strong trends toward mitigation of negative and disorganized symptom domain. Seventy-five percent of the mean daily work amount could be explained by the duration of vocational activity and the severity of the disorganized symptoms.
Conclusion:Vocational rehabilitation may bring about improvement in job-related cognitive functions and the mean daily work load may be associated with the total duration of the vocational activity performed by the mentally disabled. (Korean J Schizophr Res 2008;11:125-132)
