Non-Specific Patient Population

Career maturity can be defined as readiness to cope with vocational developmental tasks (Savickas, 1984).
The 1978 CMI includes 2 components: the Attitude Scale and the Competence Scale. There are 3 options for the Attitude Scale: the 75-item Counseling Form B-1, the 50-item Attitude Scale Form A-1 and 50-item Screening Form A-2. The five subscales of the Atitude Scale include Orientation to Career Choice, Involvement in Career Choice, Independence in Career Choice, Compromise in Career Choice, and Decisiveness in Career Choice. The response format is True or False The 100-item Competence Scale of the 1978 CMI is divided into five parts and yields five raw scores rather than a single competence test score. The five subscales are Self-Appraisal, Occupational Information, Goal Selection, Planning, and Problem Solving. Each scale consists of 20 multiple-choice items with 5 options.
The CMI-R published in 1995 has 50 items: 25 on the Attitude Scale and 25 on the Competence Test. The CMI-R yields scores for the Attitude Scale, Competence Test, and overall Career Maturity. Response is in the binary-option format: Agree or Disagree.
The most recent Career Maturity Inventory, CMI Form C (CMI-C), is a 24-item scale that measures change along four subscales of concern, consultation, curiosity, and confidence (Savickas & Porfeli, 2011).
The CMI-C generates 5 scores: total score for career choice readiness, 3 scores for the Concern, Curiosity, and Confidence Scales, and score for the Consultation Scale. The response to items is either Agree or Disagree.
Scores are calculated by adding the correct responses to items. Higher scores suggest a need for exploration in depth; lower scores suggest a need for exploration in breadth.
The CMI-C is available in the Counselling Form (for counselors and educators) and the Screening Form (for researchers and academic/career orientation directors).

Number of Items

CMI: ranges between 150-175 items
CMI-R: 50 items (25 Attitude Scale items and 25 Competence Test items)
CMI-C: 24 items

CMI-R (1978): Attitude Scale and Competence Test booklets/answer sheets and pencil for test takers; CMI administration/use manual and a timepiece for test administrator.
CMI-C (2011): Test and pencil for test taker; article by Savickas & Porfeli (2011) for test administrator

15 minutes

Time indicated is for CMI-C. The time required to administer the CMI is 2.5 hours (30 minutes for the Attitude Scale and 2 hours for the Competence Scale) and for the CMI-R it is about 30 minutes.

Considerations

CMI scores generally increase as a function of age and grade level
CMI scores have a ceiling effect once reaching adulthood
Female students report higher scores during high school when age is held constant for gender comparison, which indicates that career maturity is reached earlier for female students
Asian students’ scores tended to be lower as Asian students’ career decision-making is more heavily influenced by external influences such as family
The 1978 CMI is recommended for both research and practice, including 1) studying career development, 2) screening for career immaturity, 3) assessing guidance needs, 4) evaluating career education, and 5) testing in career counseling
The CMI-R is referred as an adult version of the 1978 CMI. However, the revision was more conceptual than empirical (Savickas & Porfeli, 2011)
CMI-C is used for teaching adolescents the process of career decision making and fostering career maturity.

Standard Error of Measurement (SEM)

US High School Students (calculated from Busacca & Taber, 2002; n = 157; 72 males, 85 females; mean age = 16.07 (1.18) years; administered with the CMI-R)

SEM for male participants (n = 82): 3.329
SEM for the Attitude Scale (n = 157): 1.974

Construct Validity

Convergent validity:

Adequate correlation of the Attitude Scale (Form A-2) of the 1978 CMI with the Extent of Planning Scale of the Career Development Inventory (r = 0.37)

Floor/Ceiling Effects

Researchers predicted and reported a ceiling effect over young adulthood (Savickas, 1984).

Responsiveness

Students who engaged in career counseling had, on average, a 1.30 CMI raw score increase. This difference is significant at p < 0.02 (Crites, 1978a).
