The objectives of the present research were to explore perceptions of Primary Health Care professionals towards alcoholic patients and to verify possible differences in the perceptions of male and female alcoholism. Participants read and responded to three case vignettes describing a male alcoholic, a female alcoholic and a male diabetic. Data were analyzed with repeated measures MANOVA and univariate F follow-up tests. Results showed that the alcoholic was objectified as an “atypical and difficult” patient towards whom there were negative attitudes and stigma-related socio-cognitive elements. Female alcoholism was possibly perceived as more difficult to explain than male alcoholism. The discussion highlights the importance of social representations and social identities in the continued training of health personnel.
