indirect effects

Hello all, I'm testing for mediation using bootstrapping in AMOS. This method reports results for two-tailed significance, but my hypotheses are directional. With bootstrapping, significance is assessed based on confidence intervals - though a p-value is also provided. For regression, I would...

Hi, I am performing mediation analysis using structural equation modelling (I'm using the lavaan package in 'R'). I am using the bootstrapping approach (rather than the causal steps approach) and just wanted to clarify two things; 1) My understanding is that using this approach, the the...

Screenshot of Output attached! Hey all, I am new to this forum and wanted to ask for some help with regards to interpreting a mediation output, which I ran in SPSS using Hayes PROCESS macro. I am aware that the effect below suggests that there is no mediation because the indirect...

I need to establish the efficacy of a test treatment (T) by means of an indirect comparison to placebo (P). Therefore a study of T vs. reference (R) will be performed, and there is 'historical' data for the comparison between R and P. The outcome measure of interest is a responder rate (i.e...

I know the current view (contrary to Baron & Kenny) is that you do not need to find a significant direct effect to test for mediation (e.g., Shrout & Bolger). However, can you still test for mediation if you do not hypothesize a direct effect? For example, I'm testing a model in which X...
