It was possible to quantify the positive impact of a self-practice/self-reflection (SP/SR) training and development programme within a cohort of experienced cognitive-behavioural (CBT) therapists.Through SP/SR, experienced CBT therapists can further enhance their self-perceived therapeutic skills in two key domains; technical cognitive therapy skills and interpersonal empathic skill.Further SP/SR studies should aim to incorporate objective measurement of therapeutic skill, ideally from more than one rating source.
