Strengthening Mental Health Worldwide

What are the DISC & DISCUS scales?

The DISC is an interview-based scale which measures experiences of mental health-related discrimination (‘being treated unfairly’) in key areas of everyday life and social participation, including work, marriage, parenting, housing, leisure, and religious activities. It has 32 questions. The DISC is designed to be completed by people who have experience of mental health problems. It is a reliable and valid measure and has been used in over 60 countries around the world.

The Discrimination and Stigma Scale (DISC-12) was specifically developed to measure experienced and anticipated discrimination reported by people with mental health problems. However, the length of the DISC-12 may represent a disadvantage especially in country settings with limited human capacity and infrastructure. A short version of DISC-12 was developed –DISCUS– to address these limitations. The DISCUS scale is a consistent and valid instrument to measure experienced and anticipated discrimination predominantly in personal and social relationships in global settings.

For the DISCUS scale ratings are given on a 4-point Likert scale (0=“no difference”, 1 = “a little”, 2 = “moderately”, 3 = “a lot”). Individuals may also indicate that a given item is ‘not applicable’ to them, usually because they had not been in that situation (for example, experiencing discrimination in relation to having a child when the participant did not have any children).We excluded the item‘other’ as it did not to contribute specific information needed for the construction of latent constructs.
