Differences in general population on knowledge, attitudes and behaviour related to mental health stigmaABSTRACT: Stigma in mental health is studied in a sample of 152 subjects of Almería city population with the aim of designing specific anti-stigma campaigns. For this, Stigma is operatized in three constructs: Knowledge, Attitudes and Behaviour, using MAKS, CAMI and RIBS scales for these. Results show that the younger group, under thirty-five years old are less knowledgeable about mental health related to stigma, showing a significant difference (p< .05). Moreover, we found significant differences in gender regarding the intention of stigmatizing behaviour (p=.049) as well as attitudes (p= .006) where men have more stigmatizing behaviour and attitudes than women. These results together with those that show a significant correlation between knowledge and behaviour, as well as between attitudes and behaviour will be used as a guide to design interventions aimed to reduce stigma in mental health.
