Abstract

The construct of concentration was refined and a 49-item self-report scale was developed. The development of the Concentration Scale (CS) included factor analysis, reliability, and construct validity testing. In Study 1, 202 college students completed the preliminary CS. An exploratory factor analysis yielded four factors which accounted for 46% of the variance in CS scores. The reliability of CS was found to be .93 (Cronbach's alpha). In Study 2, 130 college students completed the revised CS, the Mindfulness Questionnaire (MQ; Mikulas, 1990), the Boredom Proneness Scale (BPS; Farmer & Sundberg, 1986), and the Adult Behavior Checklist (ABC; Barkley & Murphy, 1998). As expected, significant positive correlations were observed between CS total scores and the measure of mindfulness, while significant negative relationships were found between CS scores and the measures of boredom proneness and attention-deficit hyperactive disorder (ADHD). The subscales scores of MQ, BPS, and ABC together were found to be significant predictors (R2 = .54) of CS scores. The findings are discussed in terms of how CS provides a measure of the construct, and how CS can be used in a variety of applied settings (e.g., counseling, academia, and industry).
