Background: Self-criticism is associated with an elevated risk of developing recurrent depressive episodes. Self-criticism can have different forms, functions and underpinning emotions. An investigation into variations of self-criticism and its antidotes is therefore warranted. The aim of this study, embedded within a randomised efficacy trial of mindfulness-based cognitive therapy (MBCT), was to explore the effect of MBCT on self-to-self relating within three domains: self-inadequacy, self-hate and the ability to self-reassure. We also investigated whether these forms of self-to-self relating predicted depressive relapse for the MBCT participants within a time frame of two years after the intervention.Methods: Sixty-eight individuals with recurrent depressive disorder were randomised to MBCT or a waiting list condition (WLC). Participants in the MBCT intervention were assessed for depressive relapse at follow-up after 6, 12 and 24 months.Results: Compared with WLC (N = 30), completers of MBCT (N = 26) showed a significant improvement in Reassure self (d = 0.69, p = .016) and a significant reduction in Inadequate self (d = 0.51, p = .021), measured with the Forms of Self-Criticizing and Reassuring Scale. There were no significant changes in Hated self. Improvements in the Reassure self during the intervention predicted non-occurrence of depressive relapse within a period of two years after the MBCT intervention.
Conclusions:Findings from the present study support evidence that MBCT can affect how individuals relate to themselves in difficult situations in ways that may act as protection against depressive relapse.
