Objective. The purpose of this study was to predict the length of employment (in months) from a common occupational profile as derived from the MBTI and WAIQ scores. This study employed the MBTI and the WAI instruments to gather information about subjects' personality types and temperament traits. These measures were used to predict length of employment for individuals with AS/HFA. Methods. A convenience sample of N=83 adults self -disclosed with AS/HFA completed the MBTI and WAI instruments. Backward Elimination Multiple Regression was used for data analysis. Results. A standard multiple regression analyses with average months on the job as the dependent variable and WAIQ, Gender (GND), age (AGE) and the subscales for the MBTI as the predictors was conducted. R for regression was significantly different from zero, F (7,75) = 8.20, p< .001. The statistically significant predictors were WAIQ (t = - 2.18, p < .05), GND (t=-3.14 p < .05), and AGE (t = 5.79, p < .001). A backward elimination model was conducted for the same predictors and dependent variable. After step 4, R = 0.65, F(4,78) = 14.17, p < .001. The statistically significant predictors were WAIQ (t = - 2.20, p < .05), GND (t=-3.40 p < .05), AGE (t = 6.39, p < .001), and SNS (t = -2.17, p < .05). A backward elimination model was also conducted on average months on the job (dependent variable) with the WAIQ and MBTI subscores as predictors. After step 7, with the remaining variables in the equation, R = 0.52, F(4,78) = 7.06, p < .001. The predictors that emerged statistically significant were Activity Raw score (t = - 2.76, p < .01), Sociability Raw score (t=1.70, p = .06), Assertiveness Raw score (t = -3.62, p < .01), and SNS (t = -2.17, p < .01). Conclusion. The data supports the identification of an Occupational Profile for adults with AS/HFA. The results support the development of interventions to assist individuals with AS/HFA in the workplace to potentially increase the likelihood of successful job performance as measured by length of employment.
