Pretreatment and posttreatment MMPI scores of 821 patients who completed a chronic pain program were submitted to a multivariate analysis of variance, examining the effects of age, gender, and insurance sponsorship. With the exception of scale 9, all clinical scales were significantly lower at posttreatment. Only the sponsorship variable was found to be a moderator variable for these treatment effects, with decreases on scales 1, 2, 3, and 0 attenuated in subjects with Worker's Compensation sponsorship compared to other sponsorship. Suggestions for further multivariate research with this population are discussed. © 2002 Wiley Periodicals, Inc. J Clin Psychol 58: 827–832, 2002.
