The Mini-iPiP Scale

(Donnellan et al., 2006)
Instructions: Below are phrases describing people’s behaviors. Please use the rating scale below to describe how accurately each statement describes you. Describe yourself as you generally are now, not as you wish to be in the future. Describe yourself as you honestly see yourself, in relation to other people you know of the same sex as you are, and roughly your same age. Please read each statement carefully, and put a number from 1 to 5 next to it to describe how accurately the statement describes you.

1 = Very inaccurate
2 = Moderately inaccurate
3 = Neither inaccurate nor accurate 4 = Moderately accurate
5 = Very accurate

1. Am the life of the party (E)
2. Sympathize with others’ feelings (A)
3. Get chores done right away (C)
4. Have frequent mood swings (N)
5. Have a vivid imagination (O)
6. Don’t talk a lot (E)
7. Am not interested in other people’s problems (A)
8. Often forget to put things back in their proper place (C)
9. Am relaxed most of the time (N)
10. Am not interested in abstract ideas (O)
11. Talk to a lot of different people at parties (E)
12. Feel others’ emotions (A)
13. Like order (C)
14. Get upset easily (N)
15. Have difficulty understanding abstract ideas (O)
16. Keep in the background (E)
17. Am not really interested in others (A)
18. Make a mess of things (C)
19. Seldom feel blue (N)
20. Do not have a good imagination (O)

Scoring: The first thing you must do is to reverse the items that are worded in the opposite direction. In order to do this, subtract the number you put for that item from 6. So if you put a 4, for instance, it will become a 2. Cross out the score you put when you took the scale, and put the new number in representing your score subtracted from the number 6.

Items to be reversed in this way:

6, 7, 8, 9, 10, 15, 16, 17, 18, 19, 20

Next, you need to add up the scores for each of the five OCEAN scales (including the reversed numbers where relevant). Each OCEAN score will be the sum of four items. Place the sum next to each scale below.

Openness: Add items 5, 10, 15, 20 Conscientiousness: Add items 3, 8, 13, 18 Extraversion: Add items 1, 6, 11, 16 Agreeableness: Add items 2, 7, 12, 17 Neuroticism: Add items 4, 9,14, 19

Compare your scores to the norms below to see where you stand on each scale. If you are low on a trait, it means you are the opposite of the trait label. For example, low on Extraversion is Introversion, low on Openness is Conventional, and low on Agreeableness is Assertive.

19–20 Extremely high

17–18 Very high

14–16 High

11–13 Neither high nor low; in the middle

8–10 Low

6–7 Very low

4–5 Extremely low
