How do you interpret the moderation / Mediation test using Hayes' PROCESS tool in SPSS? When running a simple moderated regression, the statistical output of Process macro is very much the same with 'Step 1 & Step 2' hierarchical regression using SPSS's linear regression tool (regression coeff, p & t-values, mean squared error, R2 & R2 change). For your first regression, regress the mediator onto the IV. The moderator variable (or construct) changes the strength or even the direction of a relationship between two constructs in the model. E denotes the binary exposure; M denotes the mediator, which temporally succeeds the exposure and precedes the outcome; and C is the vector of preexposure variables that confound the relationship between (E, M) and Y. Finally, four conditions of moderated mediation were followed (Muller, Judd & Yzerbyt, 2005; Ng, Ang & Chan, 2008) to test hypothesis 6a and 6b stating that the indirect effect of ingratiation on supervisor satisfaction through helping behavior differs across high and low levels of ingratiation behavior.

Little is known about equity effects in primary care based physical activity interventions. • This test is available for some moderated mediation models. This study aimed to explore a possible process explaining the relationship between workaholism and sleep disorders, including two mediators: work–family conflict and emotional exhaustion. Moderated mediation may occur in multiple forms, depending on the type and number of moderators and which path or paths are moderated (Preacher, Rucker, Hayes & 2007; Edwards & Lambert, 2007). Conventionally, moderated mediation analysis is conducted through adding relevant interaction terms into a mediation model of interest. That procedure is known as "regions of significance".
