|Brief Description:||This is a 24-item self-report questionnaire that assesses positive and negative affect over the last month. Response options are on a 5-point Likert scale with the following anchors: not at all true, a little true, somewhat true, pretty true, and very true. This measure is comprised of items from previous research on affective structure (Watson & Tellegen, 1985; Zevon & Tellegen, 1982) and consists of two scales. The Negative Affect Scale (12 items) includes items on negative affective states, lack of perceived control, negative self-concept, and pessimism. The Positive Affect Scale (12 items) includes items on positive affect, positive perceived control, positive self-regard, and optimism.|
