A psychologist conducted a study to investigate the effectiveness of two different psychological interventions for Social Anxiety Disorder (SAD).
Thirty-six participants, all diagnosed with SAD, took part in the study. Before the interventions began, the psychologist recorded the number of self-reported panic episodes each participant experienced over a one-week period.
The 36 participants were then randomly assigned to one of three groups of 12.
At the end of the 8 weeks, the psychologist recorded the weekly number of panic episodes for each participant again. The results showed a significant decrease in panic episodes for Group A and Group B, while the frequency for Group C remained unchanged.
Question: Explain the purpose of Group C within this study.
