Depression, HRQoL, 5 Personality Factors
Binomial Logistic Regression showed that HRQol was not a significant predictor of the Depression data, Χ2 (1) = 2.675,p > 0.05. Although 52% (Nagelkerke R2) of the explained variance in the Depression could be explained by the HRQoL subscale, Self-Image (p =0.006), Χ2 (6) = 23.212, p = 0.001. As the Self-Image scale increased by one unit, Depression levels decreased by 0.078 (β = - 0.078). Binomial Logistic Regression showed that Neuroticism (p =0.01) was a significant predictor of the Depression data, Χ2 (5) = 12.532, p = 0.028. This means that, as Neuroticism increased by one unit, Depression levels decreased by 0.128 units (β = -0.128).
Mediation: HRQoL-Neuroticism- Stress
With the use of the PROCESS software it was shown that the mediation model between HRQoL, Neuroticism and Stress is a statistically significant predictor of Stress, F(2,44) =185.35, p =0.00. In the indirect effect of x on y the confidence intervals BootLLCI=0.0054 and BootULCI = 0.0723 are greater than 0 which shows that the mediation shows statistical significance with an effect of 0.0356 which is considered a moderate effect. The mediation model is shown in Figure 1.
