Tóm tắt

ObjectiveGroup psychotherapy research would benefit from an observational measure of group cohesion to complement existing self‐report measures. This study introduces the Therapy Process Observational Coding System‐Group Cohesion scale (TPOCS‐GC), which observationally assesses cohesion between each member and the group.MethodIn total 27 parents participated in a group parent‐training social competency intervention for children with attention deficit‐hyperactivity disorder. Independent coders double‐coded group cohesion and the alliance in 144 client‐sessions. Parents, teachers, and children completed cognitive, behavioral, and therapy participation measures.ResultsThe TPOCS‐GC demonstrated modest to strong item‐level interrater reliability and acceptable internal consistency. Group cohesion evidenced moderate stability over the course of treatment. Relations between TPOCS‐GC and theoretically linked and unrelated variables provided some evidence for construct and predictive validity.ConclusionsThis preliminary study suggests that the TPOCS‐GC is a reliable instrument that may help fill an instrumentation gap in the field.
