About the Session

TCRM Methods Workshop 2 - (Conference Attendance Credit: #3 hr)

Workshop Leaders: Thomas Ledermann, Myriam Rudaz, Matthew Fritz

Moderator: Daniel Puhlman

We present easy-to-use tools to conduct power analysis for the standard and the mediation Actor-Partner Interdependence Model (APIM) using Monte Carlo simulation techniques. For the standard APIM, Structural Equation Modeling (SEM) is compared with Multilevel Modeling (MLM) and regression analysis. For the Actor-Partner Interdependence Mediation Model (APIMeM), SEM is used to compute power for all direct effects, indirect effects, and the total effects. We illustrate how power depends on the number of dyads and the correlations among the variables and whether dyad members are distinguishable (e.g., heterosexual couples) or indistinguishable (e.g., homosexual couples)
