An analysis of the influence of insurance sponsorship on MMPI changes among patients with chronic pain

Abstract

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.

Chronic Pain and the Measurement of Personality: Do States Influence Traits?

“…Eighteen studies [13,15–18,22,35–37,39,40,42–48] addressed the issue of the stability of the MMPI with pain treatment. Two of these studies [22,43] were utilized twice (Table A1).…”

“…Of the 129 references found, 94 either did not relate to the subject area or did not have a pre‐ and postpain treatment personality measurement. The 35 remaining studies [13,15–18,20–49] were sorted into nine groups according to which personality test or inventory was utilized. It is to be noted that some studies addressed more than one personality test or inventory and were therefore utilized more than once.…”

Is Chronic Pain Associated With Somatization/Hypochondriasis? An Evidence‐Based Structured Review

“…Studies were chosen for detailed review if not excluded via the following inclusion criteria: the study addressed more than one somatic symptom or hypochondriasis; the study utilized the operational definition of somatization and/or hypochondriasis; the study was performed with CPPs. Studies fulfilling these inclusion criteria (57) 33–89 were sorted into the following groupings: addressed the association of somatization and chronic pain; addressed the association of hypochondriasis and chronic pain; addressed improvement somatization with pain treatment; addressed improvement in hypochondriasis with pain treatment; addressed the development of hypochondriasis or somatization after pain onset; and addressed whether some CPP diagnostic groups somatize more. Study relevant data were abstracted by the senior author and placed in appendix Tables A1 to A7 organized according to the above‐mentioned groupings.…”
