Question

Compare and contrast the Strong Vocational Interest Blank, the Evolution of the Strong Measures and the Campbell Interest and Skill Survey

Answer 1

The Campbell Interest and Skill Survey created by David P. Campbell is a self-report instrument that measures work-related interest and skills to help guide an individual to a specific occupational area.

The Strong Interest Inventory is a psychological test used in career assessment. It is also frequently used for educational guidance as one of the most popular personality assessment tools.

Evolution:

The test was developed in 1927 by psychologist E.K. Strong, Jr. to help people exiting the military find suitable jobs. It was revised later by Jo-Ida Hansen, and David Campbell and published as the Strong-Campbell Interest Inventory. The modern version is based on the typology (Holland Codes) of psychologist John L. Holland. The newly revised inventory consists of 291 items, each of which asks you to indicate your preference from three responses.

The Strong-Campbell Interest Inventory combined both the men’s and women’s forms into a single form. Other improvements were the use of 124 occupational scales, the continued use of 23 Basic Interest Scales, and the addition of two special scales to measure academic comfort and introversion / extroversion dimensions.

The various strong measures are:

• Occupations
• School Subjects
• Activities (Repairing a clock, preparing a speech)
• Leisure Activities
• People: Types of people (Old people, Military people)
• Characteristics:
• Preferences between paired activities. (Dealing with things Vs. Dealing with people)
  • Paring between four items of work (Data things people and ideas )
  • Self descriptive answers about oneself (Responses- Yes ,no)

The Strong Interest Inventory includes:

• Scores on the level of interest on each of the six Holland Codes or General Occupational Themes (GOTs).
• The six GOTs include: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional (RIASEC)
• Scores on 30 Basic Interest Scales (e.g. art, science, and public speaking)
• Scores on 244 Occupational Scales which indicate the similarity between the respondent's interests and those of people working in each of the 122 occupations.
• Scores on 5 Personal Style Scales (learning, working, leadership, risk-taking and team orientation).
• Scores on 3 Administrative Scales used to identify test errors or unusual profiles.
