q2 · i? · causal · r1

Exploratory sensitivity analysis in the pilot RCT excluding 2 intervention participants who experienced a mental health crisis during the study. Effect sizes became MHCS d=0.16, HHI d=−0.21, ISMI d=−0.41, MHRM d=−0.27, illustrating the potential impact of individual cases on overall outcomes.

"excluding these 2 participants from the analyses resulted in noticeably smaller change scores (MHCS: meanchange=0.25, SD 7.53; HHI: meanchange=–0.50, SD 4.36; ISMI: meanchange=0.42, SD 2.91; MHRM: meanchange=−2.25, SD 15.93) and very small to small effect sizes"
