68 Chapter 3 The CBT+ group also showed greater reductions in OBE episodes at end of treatment (p = .035; d = .46), but these differences were no longer significant at follow-up (p = .095). The end of treatment differences between treatment groups in OBE episodes were confirmed in sensitivity analyses (ML: p = .010; AD: p = .010). Secondary Outcomes Results of secondary outcome analyses are presented in Table 1. SRDs show preferable probability of improvement for CBT+ on all secondary measures at both end of treatment and follow-up; differences in secondary outcome measures that reached significance were for EDI-3 Emotional Dysregulation and for EDI-3 Low Self-Esteem. The CBT+ group experienced greater reductions in EDI-3 Emotional Dysregulation at end of treatment (p = .038; d = .43). Also, the CBT+ group experienced greater reductions in EDI-3 Low Self-Esteem at both end of treatment (p = .047; d = .56) and at follow-up (p = .033; d = .66). Results of sensitivity analyses confirmed these findings at both end of treatment (ML: p = .048; AD: p = .051) and follow-up (ML: p = .037; AD: p = .022).
