You can have a non-significant indirect effect and have a significant direct effect (which means there is not a mediation influence) or you can have a significant indirect effect and not a significant direct effect (which means X does not predict Y, but X predicts M and M predicts Y, which is a mediation).

What does indirect effect mean in research?
Definition. An indirect effect model is a statistical model of the process(es) through which intervening variables transmit effects from causal variables to outcome variables.
How do you know if mediation is partial or full?
Complete mediation is the case in which variable X no longer affects Y after M has been controlled, making path c’ zero. Partial mediation is the case in which the path from X to Y is reduced in absolute size but is still different from zero when the mediator is introduced.
How do you explain mediation effect?
If a mediation effect exists, the effect of X on Y will disappear (or at least weaken) when M is included in the regression. The effect of X on Y goes through M. If the effect of X on Y completely disappears, M fully mediates between X and Y (full mediation).
What is moderation effect?
