Criterion-related validity in a sample of migraine outpatients: the diagnostic criteria for psychosomatic research

Abstract

Objective.The Diagnostic Criteria for Psychosomatic Research (DCPR) are those of psychosomatic syndromes that did not find room in the classical taxonomy. More recently, the DCPR were updated, called DCPR-revised (DCPR-R). The present study was conducted to test the criterion-related validity of the DCPR-R.Methods.Two hundred consecutive subjects were enrolled at the Headache Center of Careggi University Hospital (Italy): 100 subjects had a diagnosis of chronic migraine (CM) and 100 had a diagnosis of episodic migraine (EM). Participants received a clinical assessment, which included the DCPR-revised Semi-Structured Interview (DCPR-R SSI), the Structured Clinical Interview for DSM-5 (SCID-5), and the psychosocial index (PSI).Results.Forty-seven subjects (23.5%) had at least one DSM-5 diagnosis: major depressive disorder (8.5%; n = 17) and agoraphobia (7.5%; n = 15) were the most frequent. One hundred and ten subjects (55%) reported a DCPR-R diagnosis: allostatic overload (29%; n = 58) and type A behavior (10.5%; n = 21) were the most frequent. When the incremental validity of the DCPR system over the DSM system was tested using PSI subscales as the criterion variable, the DCPR-R increased up to 0.11–0.24 the amount of explained variance. Subjects with at least one DCPR-R diagnosis showed lower PSI well-being scores (p = .001), higher PSI stress scores (p < .001), and higher PSI psychological distress scores (p = .008) than subjects without a DCPR-R diagnosis.Conclusion.The DCPR-R showed a good criterion-related validity in migraine outpatients. Thus, they might be implemented, together with the DSM-5, in the assessment of migraine subjects.

Allostatic Load and Its Impact on Health: A Systematic Review

“…In a recent study [269], allostatic overload based on clinimetric criteria was one of the most frequent psycho somatic diagnoses among patients with either episodic or chronic migraine.…”

Mental pain as a global person-centered outcome measure

“…The Semi-Structured Interview for DCPR-R 24 is a semi-structured interview based on the DCPR-R 16 . It yields the following diagnoses: allostatic overload, health anxiety, disease phobia, hypochondriasis, thanatophobia, illness denial, persistent somatization, alexithymia, conversion symptoms, anniversary reaction, somatic symptoms secondary to a psychiatric disorder, demoralization, demoralization with hopelessness, irritable mood, type A behavior, and alexithymia.…”

“…The DCPR-R has shown good criterion-related validity 24 and a substantial minority of patients not diagnosed according to DSM-5 satisfied the DCPR-R diagnostic criteria for a psychosomatic syndrome. 24 The CID 17 is a clinician-administered tool derived from the Hamilton Scale for Depression, 25 which covers 20 symptomatic areas assessed on a 7-point Likert scale. The individual anchor points are specified based on severity, frequency, and/or quality of symptoms.…”

Mental pain and pain-proneness in patients with migraine: results from the PAINMIG cohort-study

“…27 Thereafter, they were evaluated by trained clinical psychologists who collected sociodemographic information, data on pharmacological and nonpharmacological treatments, and on the clinical history of organic diseases via an ad hoc set of questions already used in the past. 29,30 The following assessment instruments were then administered: the Migraine Disability Assessment Score (MIDAS) questionnaire, 31 the Brief Pain Inventory (BPI), 32 the Structured Clinical Interview for DSM-5 disorders (SCID-5), 33 the Semi-Structured Interview for Diagnostic Criteria for Psychosomatic Research-Revised (SSI-DCPR-R), 34 the Clinical Interview for Depression (CID), 35 the Euthymia Scale (ES), 36 the PsychoSocial Index (PSI), 37 the Mental Pain Questionnaire (MPQ), 20 and a checklist based on Blumer and Heilbronn 25 criteria for PP.…”

“…The DCPR-R showed good criterion-related validity. 34 The CID 35 is a clinician-administered tool derived from the Hamilton Scale for Depression 39 and covering 20 symptomatic areas assessed on a 7-point Likert scale. The individual anchor points are specified based on gravity, frequency, and/or quality of symptoms.…”
