2008 Validity of the Strong Interest Explorer Assessment

Validity of the Strong Interest Explorer© Assessment: Using the Strong Interest Inventory® assessment as a criterion measure

Using the Strong Interest Inventory® (SII) assessment as a criterion measure, the validity of the Strong Interest Explorer© (SIE) assessment was tested. A total of 513 individuals were administered the SIE assessment and SII assessment. Theoretically meaningful correlations between the two instruments provide initial support for the validity of the Strong Interest Explorer© assessment.



2008 MBTI Step II Ethnicity Paper

MBTI® Step II Results of Community Leaders

This study was conducted to examine the effects of ethnicity on the Step II profiles of participants in Blandin Foundation’s Community Leadership Program. Results indicate that although participants within each ethnic group (i.e., American Indians, Caucasians, and Hispanics) were diverse, few significant differences were found between groups in overall modal type and on facet categories.  Additionally, no significant differences were found between groups on the six decision-making categories.



2007 SIOP Poster - CPI260 Validity CPI260® Validity: Comparing Leaders in Three Countries

This study was conducted to examine the factor structure of the CPI 260 assessment in three different countries. The similarities between the factors in U.S., Canadian, and Australian samples were examined by means of the coefficient of congruence. These results lend support for factorial validity of the CPI 260 assessment.



2007 SIOP Poster

The CPI260® Coaching Report for Leaders: Strengths and Developmental Opportunities

The current study compared over 5000 leaders who had strengths and developmental opportunities identified by the CPI260™ assessment’s Coaching Report for Leaders (CRL). Self, boss, and direct report ratings from the Center for Creative Leadership’s Benchmarks® 360 assessment were used as criterion. Results were generally supportive of the CRL categorizations.



2006 APA Poster Correlating the Newly Revised Strong Interest Inventory® with the MBTI®

This study examines the relationships between the newly revised Strong Interest Inventory® (SII) and the Myers-Briggs Type Indicator® (MBTI®) assessments, commonly used in conjunction in career counseling settings, using the largest known sample of participants who have completed both assessments. Findings suggest that where changes were made to the SII, the correlations shifted in theoretically meaningful ways. This study supports the validity and the practical utility of using the newly revised SII with the MBTI.



2006 SIOP Paper Personality Profiles of North American Professional Football Players

This study used a sample of 812 North American professional football players who completed the CPI 260® assessment. Average profiles for selected groups of players were evaluated. Logistic regression and discriminant function analyses were used to examine personality differences among groups of players, including several positions, and offense versus defense.



2005 APA Poster Gender and Ethnic Differences on CPI™ 434 Scales

This study examines gender and ethnic differences on three classes of CPI scales (folk, special purpose, and vector) using a sample of 570 employed adults. Statistically significant differences were found between the gender and ethnic groups on some of the scales. However, effect sizes show that, with the exception of the Femininity/Masculinity (F/M) scale, these differences are not meaningful; indicating that the CPI instrument functions fairly across gender and three ethnic groups studied, and can be used in combination with other measures as a selection tool.

   


2002-1 / INSK White Paper Measurement Properties of the Interest/Skills Checklist©

The measurement properties of the Interest/Skills Checklist are examined and norms for the assessment are provided. The Interest/Skills Checklist is a self-report assessment of interests and skills, following the Holland Model of career choice. The results suggest that the assessment has good internal consistency reliability, and that the factor structure generally reproduces the RIASEC model for both interests and skills.



2002-2 / SIE White Paper Instrument Development: Reliability and Validity of the Strong Interest Explorer™

This paper describes the development of the Strong Interest Explorer (SIE), a self-scorable interest assessment designed for students and early career explorers. The history of the SIE, and its relationship to the Strong Interest Inventory® assessment are discussed, along with evidence of reliability and validity. 



2002-3 / CPI Brief Technical Report

Brief Technical Report on the  CPI 260® Instrument

This report briefly describes the development of CPI 260® , along with initial norms and measurement properties. 


2002-4 / Benchmarks and CPI260® Technical Report

Comparing the CPI 260® Instrument to the Benchmarks® Scales: An Initial Validity Study

The CPI 260® instrument and the results from the Coaching Report for Leaders are compared with the Center for Creative Leadership’s Benchmarks® 360 Degree assessment. The goal of these comparisons is to examine how well the instruments and reports are related. These analyses provide an indication of the concurrent validity of the CPI 260® instrument and reports, using the Benchmarks® assessment as the criterion. Overall, the results of the analyses indicate that relationships exist where they make conceptual sense. In addition, the correlations are large enough to indicate concurrent validity, but are not so large as to suggest redundancy of the measures, and reports.. 


   
Exploring Age and Gender Differences in Vocational Interests A large cross-sectional sample of respondents who completed a research version of the Strong Interest Inventory® assessment were examined for differences in the RIASEC themes based on age and gender. The data were examined using a 2 (gender) by 5 (age category) MANOVA and follow-up ANOVAs. Anticipated gender differences were found and
replicate past research. The effects of age and age by gender interactions were significant, but very small. A linear trend across age categories with level of interest generally increasing with age was found. Some implications of the findings are discussed.


Validity of 2004 Strong Interest Inventory®: Gender and Ethnicity Effects The Strong Interest Inventory® assessment has specific content measures, the Basic Interest Scales (BISs), as well as general content measures, the General Occupational Themes (GOTs), which measure the six Holland (1997) RIASEC themes. The validity of these scales has been well studied over the years (Harmon, Hansen, Borgen, & Hammer, 1994). With a newly revised Strong assessment, it is important to begin studying the validity of the revised and new content scales. Using samples of college students (N = 1,652) and working adults (N = 1,192), we examined the value of the BISs and GOTs in predicting both college major and occupational group. Results showed increases in explanatory power when the BISs were added to the GOTs. Additionally, scale means were explored by gender and ethnicity to demonstrate generalizability of the GOTs and BISs, as well as important group differences.


Revised Strong Interest Inventory® Assessment: Gender and Vocational Interest Similarity How similar are women and men in the same occupations? Has this similarity changed over time or does it vary by the Holland (1997) Theme of occupation? These questions were examined by analyzing correlations between male and female occupational scale scores on the newly revised Strong Interest Inventory® assessment with a nationally representative sample of 2,250 employed women and men. Results indicated women and men in the same occupations generally have similar interests, that similarity of interests have been consistent over time, and that women and men in Realistic and Conventional occupations have less similar interests than people in other occupations.


Revised Strong Interest Inventory® Assessment: Content, Reliability, and Validity This paper highlights the new content of the revised Strong Interest Inventory® assessment and the effect of the changes on the Strong’s measurement properties. Substantial changes to the measures of basic interests and to the occupational samples reflect a thoughtful reaction to revolutionary shifts in the world-of-work in the late 1990s. Shifts in the work people do and the way they do it is represented on the revised Strong by incorporation of new business, technology, and team related content. The changes, and the measurement properties of the Strong following these changes, are discussed.
