Ranges of questionnaires as follows: CES-D: 0–60; Restraint: 0–21; Disinhibition: 0–16; Perceived Stress: 0–16. The Life Events Questionnaire includes 67 yes/no items but many are inconsistent with each other. In this study, the total number of life events ranged from 0–24.
For each questionnaire, groups within columns with different superscripts (i.e., a, b) differ significantly from each other in post-hoc tests with Bonferroni corrections (p<0.016).
