| Popis: | Protective behavioral strategies (PBS) are most commonly defined as behaviors that are used while drinking to reduce alcohol use and/or limit alcohol-related problems. Few studies have examined and quantified PBS use among non-college student populations. The purpose of the present two studies was to evaluate the psychometric properties of the Protective Behavioral Strategies Scale-20 (PBSS-20; Treloar, Martens, & McCarthy, 2015) among internet samples of adult drinkers. In the first study, we conducted an exploratory factor analysis of the PBSS-20 with a sample (n = 360) of adult drinkers who were recruited from Mechanical Turk. We then conducted a second study that recruited adult drinkers from Mechanical Turk and randomly split the data in half. With the first split-half sample (n = 339), we conducted a confirmatory factor analysis of the PBSS-20 and assessed the internal consistency and concurrent validity of the subscales. With the second split-half sample (n = 338), we tested measurement invariance across gender. The results support a three-factor structure of the PBSS-20 that is similar to what has been found among college students. However, six items were dropped and two Serious Harm Reduction items loaded best onto the Manner of Drinking factor. Furthermore, two subscales demonstrated adequate internal consistency and all three subscale were negatively associated with alcohol-related outcomes. Similar to college students, there was lack of measurement invariance across gender. We discuss the implications of the present findings in extending research on PBS to the more general population of U.S. adult drinkers. Highlights • Three-factor model of PBSS-20 supported among adult drinkers • Adequate reliability of two of the three PBSS-20 subscales • More frequent use of PBS associated with less alcohol use • More frequent use of PBS associated with fewer alcohol-related problems |
