The Rumination–Reflection Questionnaire (RRQ) is used to measure the two factors of self-focused attention (i.e., rumination and reflection). The RRQ (Trapnell and Campbell, 1999) has two subscales and consists of 24 items. Each subscale consists of 12 items that are measured on a 5-point Likert scale (1 = totally disagree, 2 = slightly disagree, 3 = neutral, 4 = somewhat agree, 5 = completely agree). The higher the score, the greater the tendency of the subject in this dimension (Yuan et al., 2010).
The internal consistency reliability of RRQ was satisfactory in the present study (Cronbach’s α = 0.87; for rumination subscale, Cronbach’s α = 0.84; for reflection subscale, Cronbach’s α = 0.87).
