The purpose of this psychometric study was to examine the reliability and v
alidity 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 r
otation revealed that six constructs comprised the CII: parent, teacher, an
d friend influences, negative social events, high school academic experienc
es and self-efficacy, and ethnic-gender expectations. Findings indicate tha
t the negative social events factor should be viewed as an emerging constru
ct 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.
