Figures & data
Figure 1. Theoretical serial mediation model with state anxiety and displacement behaviour as mediators between trait anxiety and experience of stress. This figure indicates the hypothesised (H) path by which the link between trait anxiety and displacement behaviour could be partially mediated by state anxiety (path a 1 a 3 – H2a), hypothesised paths by which the link between trait anxiety and the experience of stress could be partially mediated by displacement behaviour (path a 2 b 2 – H2b) or state anxiety (path a 1 b 1 – H2c), or serially mediated by these two variables in combination (path a 1 a 3 b 2 – H2d) and the hypothesised path by which the link between state anxiety and experience of stress could be partially mediated by displacement behaviour (a 3 b 2 – H2e). Path c'1 depicts the mediated regression link between trait anxiety and the experience of stress.

Figure 2. State anxiety and displacement behaviour as mediators between trait anxiety and experience of stress. Solid lines represent significant direct effects in serial mediation analysis using a bias-corrected bootstrapping in conjunction with multiple regression analysis; dashed lines indicate non-significant effects. Numbers on the lines show standardised regression weights and R 2 values reflect the percentage of explained variance (n = 42 in all cases; *indicates p < 0.05, **indicates p < 0.01).
