What are the values of unstandardized \(\hat{a}\) , \(\hat{b}\), and \(\hat{c}\)? \(\hat{a}\) = -0.62 \(\hat{b}\) = -0.16 \(\hat{c}\) = 0.59
What is the 95% confidence interval of the (unstandardized) mediation effect? Is the mediation effect significant at \(\alpha\) = .05? The 95% confidence interval is (-0.27, -0.58) and is significant at \(\alpha\) =.05.
Calculate these effect sizes for mediation effect.

2. \(\upsilon\) = 0.00185

Write a paragraph to report your results. In this mediation model, the researchers hypothesized that the relationship between attachment anxiety and depression would be mediated by reactive coping. Mediation analysis revealed a significant positive relationship between depression and reactive coping (unstandardized \(\hat{a}\) = -0.62, standardized \(\hat{a}\) = -0.29, p<0.005). There was also a significant negative relationship between attachment anxiety and reactive coping (unstandardized \(\hat{b}\) = -0.16, standardized \(\hat{b}\) = -0.18, p<0.005). Lastly, there was a significant relationship between depression and attachment anxiety (unstandardized \(\hat{c}\) = 0.59, standardized \(\hat{c}\) = 0.30, p<0.005). The mediation effect was not significant at 0.1014 (CI = 0.0254, 0.1890; \(\upsilon\) = 0.00185).
