Testing in Counseling Psychology Flashcards
The Strong Vocational Interest Blank
Shortly after World War I, E. K. Strong, Jr. and some of his colleagues began to examine the activities that members of different professions liked and disliked
people in different professional groups had different patterns of interests.
people in the same line of work had similar hobbies, liked the same types of entertainment, and read the same sorts of books and magazines
Strong set out to develop a test that would match the interests of a subject to the interests and values of a criterion group of people who were happy in the careers they had chosen
criterion keying, or the criterion-group approach
develop a test that would match the interests of a subject to the interests and values of a criterion group of people who were happy in the careers they had chosen
preliminary studies of the test - The Strong Vocational Interest Blank
groups of individuals from many professions
and occupations responded to approximately 400 items dealing with likes and dislikes related to these occupations and to leisure activities.
criterion keying then determined how the interests of new subjects resembled those of the criterion groups.
revised 1966 version of the SVIB
399 items were related to 54 occupations for men.
A separate form presented 32 different occupations for women
Items in the SVIB were weighted according to how frequently an interest occurred in a particular occupational group as opposed to how frequently it occurred in the general population.
Raw scores were converted to standard scores, with a mean of 50 and a standard deviation of 10
criterion group used in the construction of
the SVIB contained approximately
300 people, a good normative sample
SVIB - reliability
Numerous reliability studies produced impressive results, with odd–even and short-term test–retest figures generally running between the low .80’s and the low .90’s.
Long-term (20-year) test–retest coefficients ran in the respectable .60’s.
Validity data indicates that the SVIB predicted job satisfaction well (e.g., Strong & Campbell, 1966).
In addition, studies have shown that achieving one’s career aspirations contributes to job satisfaction (Iliescu, Ispas, Sulea, & Ilie, 2015)
One of the most interesting findings to emerge from the hundreds of published studies using the SVIB is that patterns of interest remain…
relatively stable over time.
Strong made a practice of asking a group of Stanford University students who took the test in the 1930s to take the test again as they grew older.
interests remain relatively stable for as long as 22 years
- most people did modify their interests slightly over this period, and a few people made complete turnabouts; nevertheless, the great majority remained consistent
Criticisms of the SVIB
Critics cited a gender bias in the scales because different tests were used for men and women.
Others complained about the lack of theory associated with the test.
The Evolution of the Strong Measures - Strong-Campbell Interest Inventory
Campbell published a new version of the SVIB, which he called the Strong-Campbell Interest Inventory (SCII).
SCII was Campbell’s (1974) response to the shortcomings of the SVIB.
.
What did campbell change?
Items from both the men’s and women’s forms of the SVIB were merged into a single form that included scales devoid of gender bias
introduced more theory into the measurement strategy- Hollands theory of vocational choice
J. L. Holland’s (1975) theory of vocational choice inspired who?
What was it
Campbell
Holland had postulated that interests express personality and that people can be classified into one or more of six categories according to their interests
Over the years, research has generally supported Holland’s ideas. For example, one detailed study that used all 437 occupational titles from the Bureau of the Census demonstrated that Holland’s system can better describe work activities, general training requirements, and occupational rewards than can a variety of competing vocational classification systems
Over the course of last 60 years, research has consistently supported the claim that occupational interests reflect personality
The Campbell Interest and Skill Survey
David Campbell began working on the Strong Vocational Interest Blank in 1960
When Strong died in 1963, Campbell, then an assistant professor at the University of
Minnesota, became the primary representative of the SVIB.
Later versions were published under the authorship of Strong and Campbell
The first version of the Strong-Campbell Interest Inventory was published in
1974.
Ownership Dispute
Campbell began working on the Strong Vocational Interest Blank in 1960 when
he was a graduate student at the University of Minnesota
Because Strong had been a professor at Stanford University, Stanford and the University of Minnesota became engaged in a legal dispute over ownership. In an out-of-court settlement in 1988, Stanford received the rights to publish the Strong Interest Inventory while
Campbell received the rights to most of the cumulative work.
Campbell published the Campbell Interest and Skill Survey (CISS) when
1992
CISS asks respondents to assess …?
What is in the scales?
their degree of interest in 200 academic
and occupational topics.
Furthermore, it assesses the degree of skill in 120 specific occupations. The system produces an 11-page profile and a 2-page report summary
The CISS ultimately yields a variety of different types of scales.-. For each of these scales, an interest level and a skill score are offered.
What other scales does the CISS offer besides the specific scales?
CISS offers an academic focus scale
that helps test takers understand how comfortable or successful they may be in an academic setting, and an extroversion scale that helps guide them to occupations with
the appropriate amount and intensity of interpersonal relations
Recently, Campbell teamed up with US News & World Report to offer the CISS online
For $19.25 plus tax, you can gain access to the 320-question survey.
The fee includes a personalized report that compares your results to the responses of
people who are successfully employed in 60 occupations, along with a comprehensive
career planner and a guide to help you interpret the results.
CISS is a continuation of the research on the
SVIB and the SCII.
CISS today
CISS is now shorter and more efficient than the older SCII. The scales are standardized with means of 50 and standard deviations of 10. As with the earlier versions, the CISS uses the theoretical structure of John Holland. The
manual provides extensive evidence for validity and reliability (Campbell, 1995).
New evidence continues to support the validity of the CISS and its subscales
Summary of the Components of the Campbell Interest and Skill Survey
Orientation scales
Seven scales describe the test taker’s occupational orientation: influencing,
organizing, helping, creating, analyzing, producing, and adventuring.
Basic scales
The basic scales provide an overview for categories of occupations. Examples of
basic scales include law/politics, counseling, and mathematics.
Occupational scales
Sixty occupational scales describe matches with particular occupations, including
attorney, engineer, guidance counselor, and math teacher.
Strong Interest Inventory (SII).
In 2007, Stanford released the new Strong, known as the Strong Interest Inventory (SII).
Previous editions - three-choice format, while the revised version - five-choice, Likert-type format with icons for “Strongly Like,” “Like,” “Indifferent,” “Dislike,” and “Strongly Dislike.”
A core component of the SII is the Basic Interest Scales (BIS) - substantial changes in work life and workplaces new SII includes 41 content scales to represent these areas, 244 occupational scales.
this one - there is more focus on careers in business and technology for both men and women. For example, 122 of the scales include different pairs for men and women.
Examples of the new normative groups include greater diversity in terms of ethnic groups, race, and diversity in the workforce.
First published evaluation of the SII
First published evaluation of the SII considered 31 college majors in a national college sample of 1403 women and 469 men to evaluate the relationships between content scales and choice of college major. The study showed substantial concurrent validity for a wide variety of college major choices
basic interest scales were the best predictors of selection of major.
