The study sought to determine the relationships between work adjustment and selected personal, educational, vocational, and familial variables among 116 mentally retarded trainees from two vocational training programs in Taiwan. Findings included, among others: older trainees were more likely to accept rules/authority than younger workers; males were better than females in work tolerance; less supervision was required for trainees who had fewer handicapping conditions, were taller, were not overweight, and had more years of school experience; job training was more important to subjects who had fewer handicapping conditions than to those who had more; special class experiences in either elementary or junior high school were a positive factor in work adjustment; present income seemed to correlate closely with work adjustment; the lower the educational level of the trainee's father, the less supervision was required; individuals having more parent support may exhibit better teamwork and be more likely to accept rules; and the lower the family economic status, the more realistic were the individuals in their job goals. The best set of predictors for work adjustment was determined to be years of school, present income, and nature of present work environment. (Author/JDD)
