Note. N = 233. B = unstandardized estimate; SE = standard error; β = standardized estimate; PTSD = posttraumatic stress disorder; prior SA = prior sexual assault (1 = prior SA, 0 = no prior SA); PIRI = Pleasant Imagery and Relaxation Instruction (coded as 1); PPRS = Prevention of Post-Rape Stress (coded as 0); TAU = Treatment as Usual (coded as 1); DAFR = Drug- or Alcohol-Facilitated Rape; minority status (minority coded as 1, non-minority coded as 0). All conditional interaction models included the main effects in addition to the interaction terms; estimates for the main effects available upon request.
