Comparison of three CFA Models (Study 1).
| MODEL | SATORRA- BENTLER χ2 | DF | SRMR | RMSEA | RMSEA 90% CI | CFI | TLI | AIC | ECVI |
|---|---|---|---|---|---|---|---|---|---|
| 4-Factor | 428.53 ** | 203 | .07 | .06 | .057–.074 | .88 | .87 | 16184.17 | 1.97 |

[i] Note: 4-Factor = four-factor model of the 22-item scale; 2-Factor = two-factor model of the 13-item scale; 1-Factor = single-factor model of the 13-item scale. df = degree of freedom; CI = confidence interval; SRMR = Standardized Root Mean Square Residual; RMSEA = Root Mean Square Error of Approximation; CFI = Comparative Fit Index; TLI = Tucker Lewis Index; AIC = Akaike Information Criterion; ECVI = Expected Cross-Validation Index. The best fitting model is shown in bold. **p < .01.

[i] Note: CEI = cognitive-emotional impairments; FI = Functional impairments; EX = Personal experience of climate change; BE = Behavioral Engagement; BDI = Beck depression inventory. GAD = general anxiety disorders; EID = environmental identity; CAS = climate anxiety scale.
