یک مدل ساختاری جدید برای مطالعه بازیگری بزرگسال: ارزیابی و اکتشاف یک متغیر فردی درک شده

Adult playfulness is an understudied personality trait. A new 28-item questionnaire (the OLIW) is proposed that assesses four basic components; namely, Other-directed, Lighthearted, Intellectual, and Whimsical playfulness. Study 1 provides support for the factorial validity in an Exploratory (N = 628) and a Confirmatory Factor Analysis (N = 1168). Item- and scale-statistics were satisfactory. Correlations in the expected range with other playfulness questionnaires provide support for the convergent validity of the scale; there was between 3 and 30% shared variance with the big five personality traits. Test-retest reliabilities were between 0.67 and 0.87 for one-week, two-week, one-month, and three-month intervals (N = 200; using a reduced set of 12 items). Study 2 found convergence between self- and peer-reports in the expected range (i.e., 44–0.57). Participants in Study 3 (N = 295) collected daily behavior ratings for 14 days for Play, Aggression, Exhibitionism, and Impulsivity, and completed respective trait measures on day one. The OLIW demonstrated correlations between 0.29 and 0.36 for the aggregated behavior ratings, which was in the expected range. Overall, the findings for the psychometrics, reliability (internal consistency, test-retest), and validity (factorial, convergent, discriminant) are satisfactory and further use of the OLIW is encouraged.
