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."

What it measures

This is the 20-item Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988) under its trait instruction: the respondent rates the extent to which they feel each mood adjective in general, on average. Positive Affect and Negative Affect are scored as separate 10-item dimensions, consistent with the two-factor structure of affect the PANAS was built to capture.

The norms shown on this page are the original 'General' instruction figures from Watson, Clark, and Tellegen's (1988) Table 1, matching the instruction set administered here.

Psychometric properties

The notes below are reproduced from the platform's psychometrics register for this instrument — the same source-cited reliability, validity, and norms text that accompanies its downloadable report.

The PANAS subscales show excellent internal consistency: Positive Affect alpha typically 0.86-0.90, Negative Affect alpha typically 0.84-0.87 across time frames and populations (Watson et al., 1988; Crawford & Henry, 2004).

The two-factor structure is robust across instruction sets and is replicated across diverse adult populations. Trait PANAS scores show high test-retest stability (r > 0.70 over several months) consistent with their measurement of dispositional affect (Watson et al., 1988).

Watson et al. (1988) report general adult norms for the trait ('in general') instruction: Positive Affect M = 29.7, SD = 7.9 (N ≈ 1,002); Negative Affect M = 14.8, SD = 5.4. Crawford & Henry (2004) UK community norms (N = 1,003) are consistent: PA M = 30.6, SD = 7.7; NA M = 15.4, SD = 5.8. Bands shown on the result page span ±1 SD from the Watson et al. (1988) published mean.

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).
