Use of common and unique techniques in the early treatment phase for cognitive-behavioral, interpersonal/emotional, and supportive listening interventions for generalized anxiety disorder.

= 40 randomly sampled participants were observationally coded with a multidimensional intervention measure, with subscales reflecting diverse theoretical orientations and common factors. Multilevel modeling was used to examine intervention use and investigate differences between treatment conditions and segments. Among the results, common factor interventions were rated as significantly more typical in cognitive-behavioral therapy compared with supportive listening. The pattern of intervention use of other subscales was generally consistent with the orientation of the respective protocols. In the early phase of treatment, supportive listening conditions do not appear to function as common factor controls in the manner that many might assume. Common factors are potentially enhanced in bona fide treatments that include a more detailed, specific rationale and clear and cohesive techniques and goals.
