Construct Validity and Predictive Validity of the Career Planning Inventory

Abstract

A longitudinal design was used to test the hypotheses that career development indices account for significant amounts of variance in the prediction of high school success, and account for unique variance beyond that of academic predictors of high school success. The participants included 188 11th-grade students who were followed-up in the 12th grade. Career knowledge scores predicted high school GPA and accounted for a significant amount of variance beyond that of the academic prediction of high school success. The results supported the hypotheses. Bivariate correlation and multiple regression indicate that career knowledge scores predicted high school GPA and accounted for a significant amount of variance beyond that of the academic predictor of high school success.

Occupational knowledge in college students: Examining relations to career certainty, career decision-making self-efficacy, and interest congruence

“…As previously reviewed in the occupational knowledge section, small relations have been found between career certainty and self-estimated levels of occupational knowledge (Multon et al, 1995;Westbrook et al, 1996). However, studies examining objective occupational knowledge and career certainty have revealed null relations with career certainty (Westbrook et al, 1996;Westbrook & Sloan, 2006). While none of these findings are addressing knowledge specific to one's chosen career, Westbrook and colleagues (1996) participants did find a strong correlation between certainty and self-estimated knowledge of the attributes required for participants' chosen careers (r = .65, N = 91; e.g., "Know the duties required in career choice," "Have information about career choice").…”

“…One study reported a small but significant correlation between career certainty and selfestimated levels of occupational knowledge (r = . 24;Multon et al, 1995), but another study examining objectively-measured occupational knowledge and certainty yielded no relation (r = .00; Westbrook & Sloan, 2006). Similarly, a study of high school students by Westbrook and colleagues (1996) failed to find a significant relation between the CVMT -Duties scale and career certainty (r = .20, N = 91).…”

“…Profile was a valid measure of occupational knowledge. Objective occupational knowledge did not significantly correlate with career certainty (Westbrook et al, 1996;Westbrook & Sloan, 2006), perceived occupational knowledge (Grotevant & Durrett, 1980), reported number of…”

“…Fouad also reported no gender differences in her sample. Conversely, Miller and Hayward (2006) found that high school females' self-estimations of occupational knowledge were higher than those of males, and two studies reported higher levels of objectively measured occupational knowledge in females (Rohlfing, et al, 2012;Westbrook & Sloan, 2006). Notably, none of these studies looked at age or gender in relation to knowledge of individuals' chosen occupations.…”

“…Developed by Westbrook (1997), this 10-item scale was designed to measure individuals' breadth of career knowledge. It was found to be used in only one study (Westbrook & Sloan, 2006) and is comprised of multiple choice questions in which participants choose the occupation that fits the job task description (e.g., "Which of the following designs buildings?" Mechanic, architect, surveyor, engineer, or "I don't know").…”
