“…Group researchers have utilized the APIM to examine actor and partner effects across a variety of variables, such as the alliance (Gullo et al, 2014), absences (Kivlighan, Kivlighan, et al, 2012; Kivlighan et al, 2014; Paquin et al, 2011), treatment outcomes (Kivlighan et al, 2016; Paquin et al, 2013), intimate behaviors (Kivlighan & Paquin, 2014; Miles et al, 2011), attachment styles (Kivlighan, Lo Coco, et al, 2012; Kivlighan et al, 2017; Lo Coco, Gullo, Oieni, et al, 2016), therapeutic factors (Kivlighan, 2011), group relationships (Lo Coco, Gullo, Di Fratello, et al, 2016), and group climate (Kivlighan & Paquin, 2014; Lo Coco et al, 2013). As an example, Kivlighan, Kivlighan, et al (2012) used the APIM to test an individual group memberās attachment and the aggregated other group membersā attachment on both an individual group memberās perception of the group climate and the aggregated other group membersā perceptions of the group climate.…”
