John Holland's theory considers congruence between the vocational interests of the individual and characteristics of the work environment to be the primary predictor of job satisfaction and stability. The managed care model has markedly changed the demands of the work environment of mental health counselors. Changes in the way services are regulated and delivered appear to be more consistent with the Conventional (C) Type in Holland's Typology, as opposed to the core characteristics of the counselor and corresponding environment Social-Artistic-Enterprising (S-A-E) that are identified in the Dictionary of Holland Occupational Codes (DHOC). This study investigated if the Social-Artistic-Enterprising (S-A-E) typology is still an accurate depiction of this work environment. Also examined was to what extent person-environment congruence predicts job satisfaction and stability, as well as differences in congruence, job satisfaction, and stability across various clinics in Maricopa County. Job Satisfaction was measured by the Job Descriptive Index and the Job In General, while job stability was measured as the number of months in current position. Congruence was calculated using the Vocational Preference Inventory for the measure of the person, while the Position Classification Inventory and the DHOC were used as separate measures of the vocational environment. The patterns of relationships between vocational personality and environmental types were examined. The sample included 107 mental health counselors practicing in managed care settings in Maricopa County. An examination of descriptive statistics suggests that though the counseling environment is predominantly Social, it places demands on counselors that are characteristic of the C Type. Through separate multiple regression analyses, neither measure of congruence significantly predicted job satisfaction or job stability. Between-subjects MANOVA revealed a significant omnibus affect, but when protecting against Type I errors using the adjusted alpha level, no significant univariate effect of the mental health agency on the dependent variables was found. Canonical correlation analysis indicated that counselors with high Social and moderate Conventional vocational personality traits tend to view the employment setting as consistent with the Social environment. These findings can be used by mental health agencies for program design and evaluation, and by counselors for career development and job selection.
