Abstract
The aims of this study were to construct a Daily Uplift Scale (DUS) for university or college students (DUS) and to investigate its reliability and validity. In Study One, eighty-five items were selected as daily uplifts for such students. In Study Two, factor analysis of data from 445 students extracted five factors: "uplifts in relations with familiar others," "uplifts in private life," "uplifts in friends and playing," "uplifts in love," and "uplifts in part-time job and club activities." The internal consistency of Cronbach's α coefficients showed that DUS had sufficiently high reliability. Furthermore, the DUS scores were correlated with the scales of subjective well-being and other daily uplifts. Confirmatory factor analysis of the scale, which consisted of 47 items, resulted in an adequate fit. Thus, the result of ANOVAs revealed that the scores of females were higher than males in "uplifts in relations with familiar others" and "uplifts on private life." Finally, the need for the study of daily uplifts in the future was discussed.
