Factor Validity

The factor structure of the me2 General Factor of Creativity was examined with Confirmatory Factor Analysis using the diagonally weighted least squares estimator as implemented in MPlus version 61 (WLSMV) showing the following fit: χ2 = 14676, df = 2418, CFI = 0.94, NNFI = 0.94.

 

Invariance Testing

The me2 General Factor of Creativity was tested for fairness across gender and ethnicity by the method of assessing factorial invariance in ordered-categorical measures, using the robust maximum likelihood estimator (Millsap & Yun-Tein, 2004)1.

 

For gender, very unusually, the models progressively improved in fit, which provides unequivocal support for fairness across gender.

 

Ethnicity was categorised as: White (N = 1917) and Non-White (N = 397). Similar to gender, and equally unusually, model fit improved as the models became more restrictive, which provides a clear demonstration of fairness across ethnic groups.

 

In total, 707 of the sample were born in non-English speaking countries, so the results also establish that the me2 General Factor of Creativity is clearly understandable by individuals for whom English is a second language.
