Effectiveness of Internet-based Dialogical Dilemma Solution Technique Compared with Cognitive-Behavioral Technique in Facilitating Problem-Solving: A Randomized Control Trial

AbstractAbstractThe Dialogical Dilemma Solution (DDS) technique is a psychological method based on dialogical self theory which aims to support decision-making processes. In the DDS technique problems are operationalized as intrapersonal decisional struggles – dilemmas between different self-aspects, each having its origin in a relationship with a particular person significant for the individual. Two studies examined the effectiveness of the DDS technique. The first pilot study was a quasi-experimental design with repeated measurements on one research group (N = 15) to which the DDS technique was applied during a 60-minute session with the psychologist. In the second study - a randomized controlled trial experiment (N = 76) performed over the Internet, the effectiveness of the DDS technique was compared with a standard CBT technique. Both studies showed that the technique was effective in facilitating problem-solving. The application of the DDS technique in Study 2 showed a higher degree of problem solution than the CBT technique and according to participants' subjective appraisal it was more helpful in understanding the problem.
