Self-acceptance is measured using 3 questions from a modified version of Ryff's Scales of Psychological Well-Being. The scale includes 3 items for each of 6 aspects of well-being: self-acceptance, autonomy, environmental mastery, purpose in life, positive relations with others, and personal growth.
Participants are asked to rate how each item applies to themselves using a 7-point Likert rating scale (see below). Items that are positively worded are flipped so that higher ratings on all individual items indicate greater self-acceptance. The score is the mean of the 3 item ratings, with a higher score relating to greater self-acceptance.
Participants are presented the following items:
| Item no. | Item | Flipped (f) |
|---|---|---|
| 1 | I like most parts of my personality. | (f) |
| 2 | When I look at the story of my life, I am pleased with how things have turned out so far. | (f) |
| 3 | In many ways, I feel disappointed about my achievements in life. |
Response choices for each item:
| Response | Value | Flipped value |
|---|---|---|
| Strongly agree | 1 | 7 |
| Agree | 2 | 6 |
| Slightly agree | 3 | 5 |
| Neither agree nor disagree | 4 | 4 |
| Slightly disagree | 5 | 3 |
| Disagree | 6 | 2 |
| Strongly disagree | 7 | 1 |
