Investigating the similarities and differences between practitioners of second- and third-wave cognitive-behavioral therapies

Abstract

There has been much discussion in the literature recently regarding the conceptual and technical differences between so-called second- (e.g., Beckian cognitive therapy) and third-wave (e.g., acceptance and commitment therapy) behavioral therapies. Previous research has not addressed the potential similarities and differences among the practitioners of these types of approaches. The current study examined possible differences in the characteristics of second-wave (n = 55) and third-wave cognitive-behavioral therapists (n = 33) using an Internet-based survey. There were differences found at the technical level between the two groups. As expected, third-wave therapists reported greater use of mindfulness/acceptance techniques. Also, third-wave therapists reported greater use of exposure techniques and second-wave therapists reported greater use of cognitive restructuring and relaxation techniques. In general, third-wave clinicians were more eclectic at the technical level and demonstrated significantly greater use of family systems techniques, existential/humanistic techniques, and the total number of techniques. No significant differences were found on the attitudinal measures administered, including reliance on an intuitive thinking style, acceptance of complementary and alternative therapies and related health beliefs, or most attitudes toward evidence-based practices. The authors did not identify many differences between second-wave and third-wave therapists other than in terms of the techniques they employ. The clinical and research implications for these findings are discussed.
