Only three vocational theories explicitly address the role of work values in career choice and development (e.g. Super's Life-Span, Life-Space Theory (Super, 1953); The Theory of Work Adjustment (Dawis & Lofquist, 1984); and Duane Brown's Values-Based, Holistic theory (Brown, 1996). However, many researchers have developed measures of work values for specific studies, causing confusion about what domains represent the construct of work values. This confusion makes it difficult to fully understand the range of relevant work values. Furthermore, limited effort has been made to explore the nomological net for the construct of work values or the relation between work values and other constructs such as vocational interests, personality, and personal values. The present study sought to examine the domain of work values, the nomological net for the construct of work values, and evidence of validity for different measures of work values by comparing multiple measures of work values. Using a sample of (N = 374) undergraduate students, results suggested that evidence of convergent and discriminant validity existed for scores on four of the five work values measures examined. Principal Components Analysis identified six components that captured the domains represented within the construct of work values. Further analyses found that work values were related to, but distinct from, interests and personality, but were most similar to personal values. Information from open-ended responses suggested that additional values may be relevant to a work situation for younger workers.
