Study: NCT05431231

Intervention type: DIAGNOSTIC_TEST
Intervention: Manchester Short Assessment of Quality
Description: a patient questionnaire that assesses quality of life. This questionnaire was developed by Priebe, Huxley, Knight and Evans in 1999. It is based on a longer questionnaire - Lancashire Quality of Life Profile (LQLP) - and was created as an attempt to form an improved shorter version. The questionnaire is composed of two parts: personal details that can change over time and 16 questions that assess objective and subjective quality of life. The objective items are presented as yes or no questions, while regarding the subjective items, participants are asked to describe, using a 7-level Likert scale, the extent to which they are satisfied with their lives. Priebe et al. reported an alpha internal consistency of 0.74.

Intervention: Self-Stigma of Mental Illness Scale
Description: a patient questionnaire that assesses internalized self-stigma. It was developed by Corrigan, Watson, and Barr in 2006. The questionnaire is composed of four dimensions. The questionnaire includes 40 items, 10 items for each dimension. The participant is asked to rate the extent to which he agrees with each item using a 9-level Likert scale. The questionnaire yields four separate scores for each dimension, and each dimension can be administered separately and independently. In the current study, only one 10-item dimension will be administered - the extent to which the participant has internalized stereotypes concerning mental illness. Corrigan et al (2006) reported an internal consistency alpha of 0.81 and a test-retest reliability ratio of 0.82 for this dimension.
