Stigmatised attitudes towards intellectual disability: A randomised crossover trial

Abstract

Aims and method: Tackling discrimination, stigma and inequalities in mental health is a major UK government objective yet people with intellectual disabilities continue to suffer serious stigma and discrimination. The project aimed to determine the effect of viewing a picture of a person with intellectual disability on stigmatised attitudes. The 20-point Attitude to Mental Illness Questionnaire (AMIQ) was used and a representative panel of members of the general public were randomised to complete the questionnaire either with (experimental) or without (control) looking at a picture of a man with Down syndrome. Six months later the same experiment was performed with the groups crossed over. Results: Results were received for 360 participants (response rate 87-93%). The sequence (control or experimental) had no significant effect on the outcome. The mean AMIQ score in the control groups was 1.56 (s.d. = 2.85, s.e. = 0.21, n = 186) and in the experiment group (after looking at the pictures) was 2.43 (s.d. = 2.59, s.e. = 0.12, n = 174; median difference 1, P = 0.0016 Mann-Whitney U-test; effect size 0.23). Clinical implications: Looking at a picture of a man with Down syndrome significantly reduces reported stigmatised attitudes. Declaration of interest: None.
