“…In studies comparing BD and MDD, the following comparisons became significant after the leave-one-out sensitivity analysis: (i) ‘ reflective pondering ’ subscale of the RRS, by removing the study (Aslan & Baldwin, 2021 ), (ii) ‘ putting into perspective ’ subscale of the CERQ, by removing the study (Wolkenstein, Zwick, Hautzinger, & Joormann, 2014 ), and (iii) ‘ goals ’ subscale of the DERS, by removing the study (Oymak Yenilmez et al, 2021 ), all passing from a small to a small-to-moderate effect size; (iv) ‘ awareness ’ subscale of the DERS, by removing the study (Musket, Hansen, Welker, Gilbert, & Gruber, 2021 ), passing from a small-to-moderate to a moderate effect size. On the contrary, by removing the studies ([Becerra et al, 2013 ], [Becerra, Bassett, & Harms, 2016 ], or [Weintraub, Van de Loo, Gitlin, & Miklowitz, 2017 ]) in the comparison relative to the ‘ clarity ’ subscale of the DERS, the overall effect became nonsignificant with an effect size comparable in magnitude.…”
