Exploration and validation of the dimensions of stigma.

Stigma research is hampered by lack of consensus about the number of dimensions making up the stigma construct and what these dimensions measure. Two studies were conducted testing the dimensionality of stigma. Using 105 items proposed to measure stigma in previous research, the first study (N = 307) conducted an exploratory factor analysis using the maximum likelihood method of factor extraction. Results supported five factors that were designated as labeling, negative attribution, separation, status loss, and controllability. Using these factors, a second study (N = 263) demonstrated support for the goodness of fit of the proposed 5-dimensional stigma model.
