99 tioning. The hypothesised model is depicted in Figure 1. Standardised coefficients of the direct and indirect effects can be interpreted as ‘small’ (.10 – .30), ‘medium’ (.30 – .50), or ‘large’ (> .50) effects (Cohen, 1992). Maximum likelihood with robust standard errors (MLR) was used to estimate the model. The ‘lavaan’ package in the R environment was used for the analyses. Both the fit indices (comparative fit index [CFI], Tucker–Lewis index [TLI], and root mean square error of approximation [RMSEA]) and the model chi-square statistic were used to evaluate model fit (Kline, 2005). The following cut-off values are indicative of a close model fit: CFI > .90, TLI > .95, and RMSEA < .08, whereas a non-significant chi-square indicates exact model fit (Cheung & Rensvold, 2002).
