Development and initial testing of a measure of public and self-stigma in the military

This research developed and tested the Military Stigma Scale (MSS), a 26-item scale, designed to measure public and self-stigma, two theorized core components of mental health stigma.

The sample comprised 1,038 active duty soldiers recruited from a large Army installation. Soldiers' mean age was 26.7 (standard deviation = 5.9) years, and 93.6% were male. The sample was randomly split into a scale development group (n = 520) and a confirmatory group (n = 518).

Factor analysis conducted with the scale development group resulted in the adoption of two factors, named public and self-stigma, accounting for 52.1% of the variance. Confirmatory factor analysis conducted with the confirmatory group indicated good fit for the two-factor model. Both factors were components of a higher order stigma factor. The public and self-stigma scales for the exploratory and confirmatory groups demonstrated good internal consistency (α = .94 and .89; α = .95 and .87, respectively). Demographic differences in stigma were consistent with theory and previous empirical research: Soldiers who had seen a mental health provider scored lower in self-stigma than those who had not.

The MSS comprises two internally consistent dimensions that appear to capture the constructs of public and self-stigma. The overall results indicate that public and self-stigma are dimensions of stigma that are relevant to active duty soldiers and suggest the need to assess these dimensions in future military stigma research.
