The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) is a well-established and widely-used instrument for assessing individual differences in well-being. The current analyses were motivated by concerns that metal wellbeing items that refer to interpersonal relationships (Items 9 and 12) may operate differently for those in a relationship compared to those not in a relationship. To assess this, the present study used item characteristic curves (ICC) and ANOVA of residuals to scrutinize the differential item functioning (DIF) of the 14 WEMWBS items for participant relationship status (n with partner = 261, n without partner = 210). Items 5, 9, and 12 showed evidence of DIF which impacted group mean differences. Item 5 (\"energy to spare\") was unexpected, however plausible explanation is discussed. For participants at the same level of mental wellbeing, those in a relationship scored higher on items 9 and 12 than those not in a relationship. This suggests these items are sensitive to non-wellbeing related variance associated with relationship status. Implications and future research directions are discussed.","PeriodicalId":73608,"journal":{"name":"Journal of applied measurement","volume":"19 2","pages":"162-172"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36216477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Rasch Analysis of the Brief Symptom Inventory-18 with African Americans.","authors":"Ruth Chu-Lien Chao, Kathy Green, Kranti Dugar, Joseph Longo","doi":"","DOIUrl":"","url":null,"abstract":"Although the United States offers some of the most advanced psychological services in the world, not everyone in U.S. shares equally in these services, and health disparities persist when assessments do not appropriately measure different populations' mental health problems. To address this assessment issue, we conducted factor and Rasch analyses to assess the psychometric characteristics of the Brief Symptom Inventory-18 (BSI-18) to evaluate whether the BSI is culturally appropriate for assessing African Americans' psychological distress. The dimensional structure of the BSI was first identified and held up under cross-validation with a second subsample. The measure was unidimensional among African Americans. Our results also suggested minimal person separation, stability across subsamples, and little differential item functioning. Most African Americans identified themselves on the low end of the categories in a 0-4 rating scale, indicating their low endorsement of the items on the BSI. Rasch analyses were completed with the original scale but also collapsing the scale to three points, with some increase in separation and reliability for the collapsed scale. Differences in mean person position were found for mental health-related variables, consistent with hypotheses. Implications for theory and research on multicultural health scales are discussed as are effects of severe item skewness on analyses.","PeriodicalId":73608,"journal":{"name":"Journal of applied measurement","volume":"19 2","pages":"173-191"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36216478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
