Analyzing Dyadic Data From Small Samples

The authors describe an approach to analyzing dyadic data that can be utilized with the smaller samples often available to researcher–practitioners working with couples in counseling. Specifically, the authors describe how to use the actor–partner interdependence model (APIM), a common dyadic data analysis tool, using a pooled regression approach that is appropriate for smaller sample sizes. An example is provided using data collected from a study of the role of expectancies in couple counseling outcomes. Additional data from the example study are provided in Appendix A for interested readers who want to practice the techniques they describe.
