The Chinese version of the Perceived Stress Scale is a validated self-report tool used to measure the degree to which situations in one's life are appraised as stressful.

Individual items are rated on a scale from 0 (never) to 4 (very often). Higher scores indicate higher levels of perceived stress (worse outcome).

The Patient Health Questionnaire-9 is a reliable self-report measure designed to evaluate the severity of depressive symptoms over the past two weeks.

Possible scores for each item range from 0 (not at all) to 3 (nearly every day).

Higher scores indicate more severe symptoms of depression (worse outcome).

Respondents rate each item on a 7-point Likert scale, where 1 represents "very strongly disagree" and 7 indicates "very strongly agree."

Higher scores indicate a higher level of perceived social support (better outcome).

The Affect Valuation Index (AVI) is a validated, self-reported instrument assessing affective experiences over the past week. It evaluates the frequency of actual emotions experienced.

Possible scores for each emotion item range from 1 (very slightly or not at all) to 5 (extremely or all the time).

Higher scores indicate a greater frequency of that specific affective state. (Note: High scores in positive affect represent a better outcome, while high scores in negative affect represent a worse outcome).

The Meaning in Life Questionnaire (MLQ) is a reliable self-assessment tool that evaluates an individual's sense of meaning in life across two subscales: Presence of Meaning and Search for Meaning.

Each subscale (5 items each) has a minimum score of 5 and a maximum score of 35.

Higher scores on the Presence subscale indicate a stronger sense that life is meaningful. Higher scores on the Search subscale indicate a greater drive to find meaning.

Higher scores on Cognitive Reappraisal indicate more frequent use of adaptive emotional regulation (better outcome).

The General Self-Efficacy Scale (GSE) measures an individual's optimistic beliefs regarding their capacity to manage challenging situations and cope with stressors.

It is using a 4-point Likert-type scale, where 1 indicates "I'm always poor at this" and 4 represents "I'm always good at this." Total scores range from 15 to 60.

Higher scores indicate a higher level of interpersonal proficiency and social skill (better outcome).
