“…However, few studies have examined whether other patient characteristics, and especially other interpersonal variables that are also predictors of alliance quality, moderate the associations between the attachment dimensions and the alliance. For example, across multiple psychotherapies for various disorders, patients’ pretreatment social support has been positively associated with the alliance (Bankoff, 1996; Hersoug, Høglend, Havik, von der Lippe, & Monsen, 2009; Hersoug, Monsen, Havik, & Høglend, 2002; Mallinckrodt, 1991; Meier, Donmall, Barrowclough, McElduff, & Heller, 2005), suggesting that patients who have quality, supportive relationships outside of therapy tend to also form more positive relationships with their therapist. Social support is also related to more positive treatment outcomes (for a meta-analysis see Roehrle & Strouse, 2008).…”
