Abstract

Background: Cancer stigma is rarely addressed among Iranian population and patients. The current study aimed at translating and examining the construct validity of the stigma scale for chronic illnesses 8-item (SSCI-8) among Iranian women with breast cancer. Methods: In the current study, a total of 223 patients aged 19-75 years were recruited from three cancer centers in Tehran, Iran, from 2014 to 2015. Forward-backward translation method was used. The item-total correlation was evaluated. Exploratory factor analysis employing maximum likelihood method and direct Oblimin rotation was conducted. Reliability was assessed using composite reliability (CR). Average variance explained (AVE) was used for convergent/divergent validity. Results: The items mean was 1.47 (0.19), the scale mean 11.75 (5.57); the inter-item correlations were positive and significant (P <0.0001). A two-factor solution with seven eligible items (five for enacted and two for internalized stigma) showed the model fitness. The CR for the total scale, as well as enacted and internalized facets was 0.78, 0.89, and 0.79, respectively; the AVE was 0.66 for each latent variable. Conclusion: The Persian version of SSCI-7 was found as a reliable and valid abbreviated instrument to assess experiences of enacted and internalized stigma among Iranian women with breast cancer.
