Model fit indices for analyses of configural and scalar invariance for age and gender

		Age			Gender
Model Fit Index		Configural	Scalar	Δχ²	Configural	Scalar	Δχ²
χ²	Statistic	119.04	139.45	21.17	86.46	109.7^*	21.82^*
	df	105	121	16	70	78	8
RMSEA	Statistic	.04	.05		.05	.06
	90% CI	.000 – .08	.000–.08		.000 – .08	.03–.09
CFI	Statistic	.98	.97		.97	.94

Note. CI = confidence interval. Non-significant chi-square difference (Δχ²) test indicates scalar invariance. Modification indices in the Mplus output indicated that removal of one item (tried a new sport or played a sport you’re not good at when you might have embarrassed yourself) would achieve full scalar invariance for gender, as indicated by a non-significant chi-square difference between the configural and scalar models (Δχ² = 6.955, p =.434).
