BACE (Barriers to Accessing Care Evaluation)  

Translations into Arabic, Cantonese, French, Italian, Kannada, Spanish (Spain), Spanish (Colombia), Portuguese and Telegu
The BACE measures barriers to accessing mental health care. It asks about 30 different barriers to care, and has a special focus on stigma-related barriers. It has a ‘treatment stigma’ subscale to assess to what extent the stigma associated with mental health care has been a barrier for an individual. It has good psychometric properties and is also being used in several studies around the world. Read this description in another language.

CODA (Costs of Discrimination Assessment)

The CODA has been developed to measure the economic costs than can arise due to the stigma and discrimination which people with mental health problems often face. The content of the CODA was based on a systematic review of the topic and on focus groups. The main sections of the CODA cover employment, health care use and avoidance, and leisure activities.

DISC and DISCUS (Discrimination and Stigma Scale) 

Translations into Swedish, Traditional Chinese (Taiwan), Arabic, Amharic, Tamil, Urdu, Turkish, Polish, Spanish

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 21 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 in over 40 countries around the world. The DISCUS is a shorter version of the DISC scale, with only 11 questions, measuring experiences and anticipated discrimination predominantly in personal and social relationships in global settings.

MAKS (Mental Illness Knowledge Schedule) 

Translations into Arabic, Czech, Cantonese, French, Japanese, Kannada and Swedish

MAKS has been developed to measure mental health-related knowledge. The tool assesses and tracks stigma-related mental health knowledge among the general public and can be used to evaluate anti-stigma interventions. If used in combination with other assessment tools that measure attitudes and behaviour, MAKS can help researchers plan and develop interventions that effectively reduce stigma. Read this description in another language.

MICA-2 and MICA-4 (Mental Illness: Clinicians’ Attitudes Scale)

The Mental Illness Clinicians’ Attitudes Scale (MICA-2) was created for use with medical students. It was found to be reliable, valid and responsive to change. An amended version (MICA-4) was validated with a sample of nursing students and may be suitable for staff and students from a wide range of health professions. The MICA has 16 questions and has been widely used around the world. Read this description in another language.

QUAD (Questionnaire on Anticipated Discrimination)

The QUAD is a new measure of anticipated discrimination. It asks people how much they personally anticipate experiencing mental health-related discrimination across 14 areas of life. The QUAD is intended for use with people who have a mental health problem. Our research showed that the QUAD is an understandable, reliable and valid questionnaire.

RIBS (Reported and Intended Behaviour Scale) 

Translations into Arabic, Cantonese, Dutch, Italian, Japanese, Kannada, French and Swedish

RIBS has been designed to assess and track mental health related behavioural discrimination among the general public. Several studies have demonstrated the significance and high prevalence of discrimination experienced by service users, emphasising the importance of assessing and documenting behavioural tends. Read this description in another language.
