In a new study that is just out in the Journal of Consulting and Clinical Psychology, researchers led by Brjánn Ljótsson studied how different possible mechanisms of CBT contributed to its efficacy in Irritable Bowel Syndrome. We used parallel process growth mediational analyses (!) to study weekly ratings of gastrointestinal symptom-specific anxiety (GSA) and stress reactivity. Results showed that only GSA displayed a pattern consistent with a causal model in which change in process preceded and contributed to symptom change.
