Table 2

Goodness-of-fit indexes of the three models tested.

	χ^2/d.f.^a	NFI	CFI	RMSEA	AIC
Model 1	0.47	0.99	1	0.00	157.06
Model 2	0.39	0.99	1	0.00	144.83
Model 3	0.40	0.99	1	0.00	158.65

Note. Model 1: optimism/pessimism → positive/negative affect → goal management strategies → activity patterns; Model 2: optimism/pessimism → goal management strategies → positive/negative affect → activity patterns; Model 3: optimism/pessimism → goal management strategies → activity patterns → positive/negative affect; NFI, Normed Fit Index; CFI, Comparative Fit Index; RMSEA, root mean-square error of approximation; AIC, Akaike Information Criterion; ^aχ²/d.f.: Satorra-Bentler chi-square divided by degrees of freedom.
