Prior research has shown that psychology-trained practitioners use homework assignments, but no prior research has sought to survey the clinical practice of other mental health professionals. Three hundred and thirty-three mental health professionals from counselling, medical, nursing, psychology, and social work training backgrounds were surveyed regarding their use of homework assignments in psychotherapy. The vast majority of the sample (83%) reported the use of homework assignments, and those practising cognitive-behavioural therapy indicated a greater frequency and degree of specificity in assigning homework. However, it was noteworthy that all theoretical and professional groups in the present study reported some use of homework assignments.
