Self-report measure

PANAS — In General (Trait Affect)

The 20-item Positive and Negative Affect Schedule, framed as a trait measure: read each word and indicate to what extent you generally feel this way, on average, in your life. Ten words measure Positive Affect (e.g., enthusiasm, alertness, energy) and ten measure Negative Affect (e.g., distress, fear, irritability). Rate each from "Very slightly or not at all" to "Extremely."

Detailed write-up pending

A full, citation-backed scientific write-up for this scale — overview, clinical use, and psychometrics in the voice of a dissertation "Measures" section — has not yet been authored. To honor the platform's no-fabricated-sources rule, this page currently shows only the verified registry facts above (item count, structure, scoring, and any published norms). No validity coefficients, reliability figures, or citations are shown here that cannot be traced to a named source; the authored write-up will be added once its sources have been read and recorded in the plan-integrity file.

Scoring & interpretation

Item responses are summed within each scale (reverse-keyed items recoded first) and expressed as a population percentile against the cited reference sample, with a reliability-based confidence range where α is published.

Watson, Clark & Tellegen (1988), Journal of Personality and Social Psychology, 54(6), 1063–1070, Table 1 — ‘General’ (‘in general’) instruction, undergraduate reference sample. Positive Affect: M = 35.0, SD = 6.4 (N = 663); Negative Affect: M = 18.1, SD = 5.9 (N = 663). Confidence range uses the standard error of measurement from the published Cronbach’s α lower bounds (PA ≥ .86, NA ≥ .84).
