The therapeutic use of homework assignments is an integral feature of Cognitive Behaviour Therapy (CBT) and is believed to be important in producing and maintaining client treatment gains. While there is empirical and theoretical support suggesting that homework completion may be associated with improved outcome, few studies have directly investigated specific therapist behaviours used in the integration of homework into practice. Similarly, research on client homework completion has, by far, focused solely on the quantity of homework completion rather than on any other factors found to be associated with increased client engagement with homework assignments. The recently developed Homework Adherence and Competence Scale (HAACS) was designed to specifically assess therapist competence and adherence to recommended homework behaviours used to administer homework. As a new measure of client homework completion, the Homework Rating Scale-II (HRS-II), extends the assessment of client homework completion beyond quantity only and provides a measure of the cognitive and behavioural determinants of client homework completion. The present study presents a psychometric evaluation of both the HAACS and HRS-II when rated by independent observers. Further, the present study sought to examine therapist differences in adherence and competence in administrating homework as well as investigating the temporal pattern of client homework completion.
