According to the theory of basic human values (Schwartz, 1992), values form a circular motivational continuum. The original publication and most subsequent research partitioned this continuum into 10 values. In theory, however, it could be partitioned into a larger number of more narrowly defined values. We use multidimensional scaling (MDS) and confirmatory factor analysis (CFA) of data from the Portrait Values Questionnaire in Poland (N = 10,439) to assess a finer partitioning of values. MDS confirmed the circular motivational continuum of 10 values, with benevolence and universalism reversing positions. CFA discriminated 15 hypothesized values: 2 subtypes of universalism (protecting the environment and societal concern), 2 of achievement (ambition and showing success), 2 of self-direction (autonomy of action and autonomy of thought), 2 of security (national security and personal security), and 2 of tradition (tradition and humility), plus stimulation, hedonism, power, conformity, and benevolence. These 15 values were also distinguishable in the MDS projection.
