The purpose of this psychometric study was to examine the reliability and validity of the Career Influence Inventory (CII), an instrument designed to assess perceived influences on career development and planning. The CII was administered to 564 undergraduates from several southwestern United States universities. Results of the exploratory factor analysis with an oblique rotation revealed that six constructs comprised the CII: parent, teacher, and friend influences, negative social events, high school academic experiences and self-efficacy, and ethnic-gender expectations. Findings indicate that the negative social events factor should be viewed as an emerging construct in comprehending career development and planning. The Cronbach's alphas for the six factors ranged from .74 to .91. The moderate correlations among most CII factors suggest the dynamic nature of career influences.Journal of Career Assessment Volume 7/Number 2/Spring 1999/Pages [187][188][189][190][191][192][193][194][195][196][197][198][199][200][201][202] Increasingly, young people are reporting a sense of being lost, especially with respect to the career path they want to pursue. It is not unusual to hear them say, &dquo;I don't have any idea about what I want to do&dquo; or &dquo; I need someone to help me with my career goals.&dquo; A lack of career direction and support has contributed to the rise in high school dropouts and has prolonged the rate of college completion (Kushman & Kinney, 1993). It is evident that educators and counselors need to help youth identify factors that might provide direction and motivation for their career plans. The purpose of the present study was to facilitate research in this area by establishing the psychometric properties of the Career Influence Inventory (CII), an instrument designed to assess factors influencing career planning.
