Tangney Self-control Scale (TSC, Tangney et al., 2004) were employed to measure self-control. It has 10 items and adopted a five-point Likert scale. In the present study, for items describing low self-control (e.g., I get distracted easily), participants responded from 1 (Not at all like me) to 5 (Very much like me). By contrast, for items describing high self-control (e.g., I'm good at resisting temptation), the coding was reversed, with 1 (Very much like me) to 5 (Not at all like me). Therefore, in the current work, a lower score means greater self-control. The reliability of TSC was 0.87.
