a study investigated the effectiveness of a new Exposure-Based Cognitive Therapy as treatment for depression. The researchers tested whether a new Exposure-Based Cognitive Therapy (EBCT) would enhance treatment gains compared to standard cognitive-behavioural therapy (CBT).

A dataset was given and an independent sample test in Jasp with the given data produced the following result for the mean depression score.

After treatment, the mean depression score for the CBT group was 11.0 (SD = 5.5 ), and for the EBCT group was 12.9 (SD = 6.5). The mean difference of -1.9 was (statistically significant )according to a Student t-test (t(198) = -2.27, p = .02), and the 95% confidence interval was [-3.6, -0.3]. The effect size was negligible (Cohen's d = -0.32 )

question:

Was EBCT more effective than CBT?
