Assessment, Statistics, and Research

  Scale name: State Joy Scale Scale overview: The State Joy Scale (SJS) is an 11-item self-report rating scale of joy with strong psychometric properties.   Response Type: There are two types of ratings. 1. Items 1-2 are rated on a 7-point frequency basis from 1 = Not at all to 7 = Frequently. See the article for the text for each of the numerical options. 2. Items 3- 11 are rated on a 7-point scale of agreement from 1 = Completely disagree to 7 = Strongly agree. Sample Scale items 1. In the past week, how often have you felt joyful? 7. Something happened this week that made me feel like celebrating.   Reliability: In study 1 of Watkins et al. (2017), Cronbach's alpha = .945. Validity: Factor analysis yielded a one-factor solution, which explained 65.17% of the variance. The State Joy Scale was significantly positively correlated with several measures including the following (correlations follow the scale names). Gratitude Questionnaire-6, .424 GRA

  Scale name: Dispositional Joy Scale (DJS) Scale overview: The Dispositional Joy Scale (DJS) is a 16-item self-report measure of joy as a trait or disposition with strong psychometric support.   Response Type: Items are rated on a scale of agreement from 1 = strongly disagree to 7 = strongly agree. The numbers 2 through 6 are not labeled. Scale items- example I often feel bursts of joy. I often feel blessed.     Reliability: Internal consistency was alpha = .954 (Study 1) and .96 and .97 (Study 2; Watkins et al., 2017). Validity: Factor analysis resulted in a one factor solution accounting for nearly 60% of the variance (Watkins et al., 2017). The Dispositional Joy Scale was significantly correlated with other positive psychology measures. Some examples follow with correlation coefficients next to the associated scale (Study 2, Watkins et al., 2017).
