The Theory of Work Adjustment (TWA) was developed in the 1960s and 1970s to help individuals successfully adjust to work environments. TWA uses assessments of individuals' abilities, values, and personalities and matches them to the requirements and reinforcers of occupations. Instruments like the General Aptitude Test Battery and Minnesota Importance Questionnaire are used to assess individuals, while the Minnesota Job Description Questionnaire assesses occupations. Counselors can then help clients find suitable career matches. TWA can benefit those choosing careers, experiencing work issues, or retiring individuals seeking part-time work. It provides a framework for counselors to understand their own strengths and better assist diverse client needs and thinking styles.
