Next, confirmatory factor analyses (CFA) were conducted to test single factor solutions for the personality scales (Neuroticism, Extraversion, Openness, Agreeableness, Conscientiousness, Sociability and Need for Cognition). Item level models were estimated using WLSMV. When assessing model fit, a range of the more reliable fit indices (Hu & Bentler, 1999) were consulted, namely, the Root Mean Square Error of Approximation (RMSEA), Comparative Fit Index (CFI), and Tucker-Lewis Index (TLI). In the case when items comprised the indicators, the Weighted Root Mean Residual (WRMR) was also used, when parcels comprised the indicators, the Standardized Root Mean Square Residual (SRMR) was consulted. The SRMR is only calculable with continuous data; and parcelled indicators closely approximate continuous data (Coffman & MacCallum, 2005). Models were considered to adequately model the data at values of 6.08 for the SRMR (Spence, 1997) and the RMSEA (Browne & Cudeck, 1993), values below 1 for the WRMR and values P.90 for the CFI and TLI, (Bentler & Bonett, 1980) with values above .95 preferred (Hu & Bentler, 1999).
