Revisiting the Drinker Inventory of Consequences: An extensive evaluation of psychometric properties in two alcohol clinical trials.

ABSTRACT: Alcohol-related consequences are linked directly to the diagnostic criteria for alcohol use disorder (AUD). However, alcohol consumption outcome variables (e.g., percent days abstinent, heavy drinking days) remain the dominant outcome in AUD treatment research. Two reasons AUD treatment researchers have not shifted to include alcohol-related consequences as a primary outcome may be that previous studies have failed to provide convincing evidence of (1) the psychometric properties of measures of alcohol-related consequences, and (2) whether consequences measures are sensitive to change following treatment. The present study directly addresses these two concerns via psychometric evaluation and sensitivity/specificity testing of the Drinker Inventory of Consequences (DrInC; Miller, Tonigan, & Longabaugh, 1995) in two of the largest multisite clinical trials ever conducted (COMBINE Study, Anton, et al., 2006; and Project MATCH, Project MATCH Research Group, 1997). Results indicated that the five subscales commonly used for the DrInC had poor construct validity and were noninvariant across time. A newly developed three-factor model consisting of mild, moderate, and severe consequences had excellent psychometrics, including good internal consistency reliability, construct validity, and measurement invariance over time. The three-factor model of the DrInC was also sensitive and specific for detecting consumption outcomes in both COMBINE and MATCH and had convergent validity with measures of consumption and wellbeing. In conclusion, the three-factor DrInC may be a useful tool for defining AUD treatment success in a clinically meaningful way that aligns with diagnostic criteria. (PsycINFO Database Record

Project description:BackgroundPregnancy is one of the most sensitive and important stages of women's life. Maternal health literacy is the key to achieving a healthy pregnancy. It also affects pregnancy outcomes by improving the quality of health care in this period. The aim of this study was to develop and evaluate the psychometric properties of maternal health literacy inventory in pregnancy (MHELIP).MethodsThis sequential, exploratory and mixed study was carried out in two parts (qualitative study and psychometric evaluation of the tool) in Tehran in 2016-18. The first part involved a qualitative content analysis with a traditional approach using in-depth, semi-structured and personal interviews with 19 eligible pregnant women. Then, the pool of items extracted from the qualitative part was completed by reviewing the existing literature and tools. In the second part, the overlapping items were summarized and the tool was validated. In order to evaluate the construct validity, a cross-sectional study was conducted with the participation of 320 pregnant women. Data analysis was performed by SPSS-19 software using exploratory factor analysis and reliability tests (Cronbach's alpha and ICC).ResultsFindings of qualitative part produced a pool of 120 items that reached to 124 items after reviewing the literature. After confirming face and content validity by calculating CVI and CVR for each item, 53 items remained in the pool. Finally, the results of exploratory factor analysis confirmed a tool with 48 items in four factors, explaining 46.49% of the variance of total variables of the tool. Reliability of the tool was approved by Cronbach's alpha = 0.94 and test-retest with 2-weeks intervals, indicating an appropriate stability for the scale (ICC = 0.96). Finally, the tool was finalized with 48 items in 4 dimensions, including "Maternal Health Knowledge", "Maternal Health Information Search", "Maternal Health Information Assessment" and "Maternal Health Decision Making and Behavior".ConclusionThe designed tool is a multidimensional, reliable and validated scale for assessing maternal health literacy during pregnancy. This tool can be used to evaluate different aspects of maternal health literacy in pregnant women, which was prepared based on their experiences during a qualitative study.
