Results of pattern-mixture model sensitivity analysis based on multiple imputation^a.

Model	Estimateb	P value
MARc	−0.34	.002

^aModels are based on varying assumptions regarding the meaning of missingness. Multiply imputed posttest values based on 100 imputations are offset [23] by varying amounts (ie, 0.20, 0.50, and residual SD).

^bCoefficient for active group status (vs waitlist) predicting posttest distress scores controlling for pretest distress scores pooled across imputed data sets.

^cMAR: missing at random (with no offset applied to posttest values).
