Four public-domain statements, answered on a five-point scale. Items marked − are reverse keyed: agreeing with them counts against the trait, which is what stops agreeing with everything from producing a high score.

• +Radiate joy
• +Have a lot of fun
• +Love life
• +Look at the bright side of life
