The Other as Shamer Scale – 2: Development and validation of a short version of a measure of external shame
MetadataShow full item record
AbstractExternal shame arises from the perception of negative judgements about the self in the mind of others and is currently measured by Other As Shamer Scale (OAS). This scale has been used in numerous studies. This study sought to develop a valid and reliable shorter form of the scale, called OAS2, in an adult sample of 690 participants, using experts’ item ratings and Confirmatory Factor Analysis. The OAS2 consisted of 8 items, which replicated the unidimensional structure of the OAS (Matos et al., 2011) and revealed a good fit. The OAS2 had good internal consistency (.82), similar to the longer version. The OAS2 has good concurrent and divergent validity, being highly correlated with the OAS (r = .91). The OAS and OAS2 have very similar significant correlations with measures of internal shame, psychopathology and anger, with no significant difference between them. Our results, suggest that the OAS2 is an economic, valid and reliable measure of external shame.
