Note(s):

Total effect and indirects effect use bias corrected bootstrapping with 5,000 samples. Direct effects are ML estimates. B = unstandardized estimate; β = standardized estimate; SE(B) = standard error of B; LCI = lower 2.5% confidence interval; UCI = upper 2.5% confidence interval. Confidence intervals are unstandardized. Blame was measured on a seven-point semantic differential scale where higher (lower) values indicate more blame placed on the service firm (reviewer)
