Model fit and parameter estimates for confirmatory factor analysis of PSQ in Uganda sample with and without mania items
| 1-factor solution with the mania item N = 2,101* | ||
| Fit statistics: | ||
| χ2 [df, p] = 2.188 [8, 0.975] | ||
| RMSEA (90% CI) = 0.000 (0.000 to 0.017) | ||
|
CFI = 1.000 TLI = 1.000 |
||
| Model results: | ||
| Standardized factor loadings | (SE) | |
| PSQ item: | ||
| Thought interference | 0.79 | (0.04) |
| Paranoia | 0.79 | (0.04) |
| Strange experience | 0.78 | (0.04) |
| Hallucination | 0.78 | (0.04) |
| Mania | 0.72 | (0.06) |
Note: RMSEA = root mean square error of approximation; CFI = comparative fit index; TLI = Tucker–Lewis index; SE = standard error
*3 participants were not included in the analysis because they had missing data on all PSQ items
