Abstract

Objective: This study examined the reliability and validity of a Shame and Stigma Scale (SSS) and assessed shame and stigma among patients with facial disfigurement from nasopharyngeal carcinoma (NPC).

Methods: Data were collected from 218 patients with NPC through a cross-sectional survey between January 14, 2020, and December 1, 2020. The original SSS is a 20-item scale with four dimensions (i.e., shame with appearance, sense of stigma, regret, and social/speech concern). We used Cronbach's alpha and McDonald's omega to assess reliability and exploratory factor analysis (EFA) to assess the factor structure. We also used Pearson correlation analysis to examine the relationship between each item and total score of scale items and convergent validity.

Results: The final 18-item SSS had a Cronbach's alpha coefficient of .89. The EFA revealed that the SSS has a four-factor structure: sense of stigma, social/speech concern, shame with appearance, and regret. These factors showed satisfactory reliability, with McDonald's omega coefficients of .87, .77, .86, and .79, respectively. The scale showed significant relationship between each item and total score of scale items with respect to item-total correlations, item-subscale correlations, and item-other-subscale correlations. Convergent validity was supported by the significant positively correlated with the total scores for depression and anxiety.

Conclusion: The SSS is valid and reliable in assessing shame and stigma and monitoring treatment compliance among patients with NPC.
