From the International Personality Item Pool (2001) / Colquitt et al. 2006 OBHDP

The Colquitt et al has the following (risk averse, page 118):

Risk aversion was also assessed using 6 items from the International Personality Item Pool (2001). Items included:

1. I enjoy being reckless (R)
2. I take risks (R)
3. I seek danger (R)
4. I seek adventure (R)
5. I would never go hang-gliding or bungee jumping
6. I would never make a high risk investment

Coefficient for this scale was .82.

I ran these from the IPIP (risk taking) :

1. I enjoy being reckless
2. I take risks
3. I seek danger
4. I seek adventure
5. I am willing to try anything once
6. I would never make a high risk investment (R)
7. I avoid dangerous situations (R)
8. I do crazy things

recode risktaking_6 risktaking_7  (1=7) (2=6) (3=5) (4=4) (5=3) (6=2) (7=1) (ELSE=SYSMIS) into risktaking_6r risktaking_7r.
compute risktaking=mean(risktaking_1, risktaking_2, risktaking_3, risktaking_4, risktaking_5, risktaking_6r, risktaking_7r, risktaking_8).
EXECUTE.
