Cultural adaptation and validation of the Others as Shamer scale: a barrier to effective health-care assessment

Abstract

PurposeDespite the fact that shame is recognized as a significant factor in clinical encounters, it is under-recognized, under-researched and under-theorized in health prevention, assessment and cross-cultural contexts. Thus, this study aims to investigate the psychometric properties of the most widely used scale, the “Other as Shamer Scale” (OAS), to assess the risk and proclivities of external shame in adults. As in health care, there is a barrier between what is known through research in one culture and what is acceptable in practice in another culture.Design/methodology/approachThe Urdu version was prepared using the standard back-translation method, and the study was conducted from June 2021 to January 2022. The translation and adaptation were completed in four steps: forward translation, adaptation and translation, back translation, committee approach and cross-language validation. The sample, selected through the purposive sampling method, is comprised of 200 adults (men = 100 and women = 100), with an age range of 18–60 years (M = 28, SD = 5.5), spanning all stages of life. The Cronbach's alpha reliability and factorial validity of the OAS were assessed through confirmatory factor analysis and Pearson correlation analyses. Internal consistency and test–retest reliability (at a two-week interval) were used to evaluate the reliability. Statistical analyses were performed using Statistical Package for Social Sciences (version 22) software.FindingsPreliminary analysis revealed that the overall instrument had good internal consistency (Urdu OAS a = 0.91; English OAS a = 0.92) as well as test–retest correlation coefficients for 15 days (r = 0.88). The factor loading of all items ranged from 0.69 to 0.9, which explained the significant level and indicated the model's overall goodness of fit.Originality/valueFindings suggest that this scale has significant psychometric properties and the potential to be used as a valid, reliable and cost-effective clinical and research instrument. This study contributes to scientific knowledge and helps to develop and test indigenous cross-cultural instruments that can be used to examine external shame in Pakistani people.
