“…This would be of potential benefit to participants if intervention were part of the design, targeting reduction in derailment. Alternatively, building upon the strengths of this study's methodology, further correlational research incorporating theoretically relevant exogenous variables, for instance factors related to self-criticism, such as shame (Kotera, Green, et al, 2019), or mediators of self-criticism and self-reassurance, such as cognitive fusion (Noureen & Malik, 2019), could improve our understanding of the relationships and directions of effects suggested in the present findings. Working within the same paradigm, it would also be instructive to probe further the effect derailment has on the sub-scales of self-criticism, and at different severities of depression, taking into account the clinical classifications made at boundary scores of the PHQ-9; anticipating that hated self and inadequate self (Castilho et al, 2015;Kotera, Dosedlova, et al, 2021), and mild, moderate or severe depression (Tolentino & Schmidt, 2018), may each have discernibly different relation to derailment (Ratner et al, 2020).…”
