TY - JOUR AU - Stewart-Brown, Sarah AB - Background: There is increasing international interest in the concept of mental well-being and its contribution to all aspects of human life. Demand for instruments to monitor mental well-being at a population level and evaluate mental health promotion initiatives is growing. This article describes the development and validation of a new scale, comprised only of positively worded items relating to different aspects of positive mental health: the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS). Methods: WEMWBS was developed by an expert panel drawing on current academic literature, qualitative research with focus groups, and psychometric testing of an existing scale. It was validated on a student and representative population sample. Content validity was assessed by reviewing the frequency of complete responses and the distribution of responses to each item. Confirmatory factor analysis was used to test the hypothesis that the scale measured a single construct. Internal consistency was assessed using Cronbach's alpha. Criterion validity was explored in terms of correlations between WEMWBS and other scales and by testing whether the scale discriminated between population groups in line with pre-specified hypotheses. Test- retest reliability was assessed at one week using intra-class correlation coefficients. Susceptibility to bias was measured using the Balanced Inventory of Desired TI - The Warwick-Edinburgh Mental Well-being Scale (WEMWBS): development and UK validation JF - Health and Quality of Life Outcomes DO - 10.1186/1477-7525-5-63 DA - 2007-11-27 UR - https://www.deepdyve.com/lp/springer-journals/the-warwick-edinburgh-mental-well-being-scale-wemwbs-development-and-5M98Gs8jFw SP - 1 EP - 13 VL - 5 IS - 1 DP - DeepDyve ER -
