Although many people with mental illness (PMI) may self-concur with negative stereotypes of mental illness ('stereotype self-concurrence”) at some point, they may have different degrees of habitual recurrence of such self-defeating perceptions ('habitual self-stigma”), which could further exacerbate the experience of self-stigma and perpetuate its adverse effects on mental well-being. The present study evaluated the prevalence of stereotype self-concurrence and habitual self-stigma in a community sample of 187 PMI in Hong Kong.

Stereotype self-concurrence was assessed using the Self-Stigma Scale—Short Form. The 9-item SSS-SF was rated on a 6-point Likert scale from 1 (strongly disagree) to 6 (strongly agree). Categories of minimal (<3), mild (3-3.5), moderate (3.5-4), and severe (>4) levels of stereotype self-concurrence were defined based on the mean scores of SSS-SF.

Habitual self-stigma was assessed using the Self-stigmatizing Thinking’s Automaticity and Repetition (STAR) scale. The 8-item STAR was rated on a 5-point Likert scale from 1 (strongly disagree) to 5 (strongly agree). Categories of minimal (<2), mild (2-3), moderate (3-4), and severe (>4) levels of habitual self-stigma were defined based on the mean scores of STAR.

Stereotype self-concurrence was minimal in 40.1% of participants, mild in 9.1%, moderate in 16.6%, and severe in 34.2%. Among participants with mild-to-severe stereotype self-concurrence, the prevalence of minimal, mild, moderate, and severe habitual self-stigma was, respectively, 2.7%, 33%, 56.3%, and 8%.

Self-stigma appears to be a common experience among PMI. The development of interventions to target stereotype self-concurrence and habitual self-stigma deserves high priority in research efforts.
