Psychometric properties of the Multidimensional Pain Inventory, Dutch language version (MPI-DLV).

The purpose of this study was to investigate the psychometric properties of a Dutch translation of the Multidimensional Pain Inventory, MPI-DLV. Data was available on 733 chronic pain patients. There were three issues of special interest. The first one related to the comparability between the MPI-DLV and the American and German MPI versions with regard to the psychometric aspects. The second dealt with the construct validity of the MPI-DLV scale 'general activity'. It was predicted that patients with high scores on this scale would be in better physical condition, as measured on a working-to-tolerance bicycle ergometer test. In relation to the third issue, attention was given to the factor-invariance between fibromyalgia patients and back pain patients. From the results obtained it was concluded that (1) the factorial structure of the three MPI parts is replicated and the reliability estimates and validity indicators are similar to those from the American and German versions; (2) patients with high scores on the 'general activity' scale are in better physical condition and (3) MPI-DLVs of fibromyalgia and back pain patients do have similar factorial structures. Evidence was also obtained that the MPI-DLV is sensitive to treatment changes. Applications of the MPI-DLV are discussed.

Validating the MPI-DLV using experience sampling data.

The present study investigates the relationship between scale scores on the Dutch version of the Multidimensional Pain Inventory (MPI-DLV) and data derived from comparable items from an experience sampling procedure. Fifty-seven chronic pain patients participated in the study, which lasted 6 consecutive days. Special attention was given to the relationship between the MPI-DLV pain intensity score and the mean experience sampling pain intensity score. Significant correlations were found between the MPI-DLV scales Pain Severity, Interference, Solicitous, Punishing and Distracting Responses, and Household Chores and their experience sampling analogues. A marginally significant correlation was found with regard to the MPI-DLV Life Control scale. The General Activity and Affective Distress scales had no relationship with the analogous experience sampling items. The significant correlations were regarded as further validation of the MPI-DLV. A regression analysis revealed that 58% of the variance of the experience sampling pain intensity score could be explained by the MPI-DLV present pain intensity item score.

Operant conditioning of the pain experience.

Two experiments were carried out to study operant conditioning of pain report. Further, it was investigated whether pain-related psychophysiological and psychological measures (skin conductance response and magnitude matching) could also be conditioned operantly. In both experiments subjects received 12 painful electric shocks of equal intensity. In Exp. 1 healthy subjects were assigned to either a control group or an up-conditioning group. Up-conditioning occurred by verbally rewarding increases in pain report and punishing decreases. Analyses indicated that up-conditioning of both pain report and the pain-related psychophysiological measures succeeded. To rule out alternative explanations of the results (attention shift towards pain and conditioning of anxiety) the verbal punishments were adjusted in Exp. 2. A down-conditioning group was also added. The attempt to replicate the results of Exp. 1 failed and down-conditioning of the pain report could not be established. These inconsistent results are most probably due to modified punishment of responses. The consequences for the results of Exp. 1 are discussed. Based on the results of post hoc analyses, some suggestions are made for operant conditioning studies of pain.

[Pain in children: introduction].

Based upon the definition of pain by the International Association for the Study of Pain, the concept of pain has been differentiated into nociception, sensation, experience and behaviour (Loeser's model). The physiology of the modulation of pain is represented by the theory of Melzack & Wall. Some specific childhood problems in the experience and the assessment of pain are discussed.

What do chronic pain patients think of their pain? Towards a pain cognition questionnaire.

The three-systems model of chronic pain emphasizes the partially independent relationship among physiological, gross motor and verbal-cognitive responses of chronic pain patients. This study describes the development of an assessment instrument representing a measure for the verbal-cognitive response system of chronic pain. Fifty items, each of which is assigned to one of five factors (pain impact, catastrophizing, outcome efficacy, acquiescence and reliance on health care) constitute the new Pain Cognition List (PCL). The PCL was developed using a Dutch back pain population and proves to be stable across sex and back pain diagnosis. By means of three experiments the PCL is shown to be reliable and sufficiently valid. The PCL might be a promising tool for identifying pain patients whose pain problem is mainly controlled by cognitive factors.

A back school in The Netherlands: evaluating the results.

The use of an education program for patients with chronic low back pain (Back School) has been investigated. The effect evaluation is based on a pretest-post-test-control group design, including a follow-up after 8 weeks. The Maastricht Back School is based on the theory that pain is also maintained by emotional, cognitive and environmental factors. Information and training are given on these and physical factors. The purpose of the course is to teach patients to manage their own pain problem. The results suggest that the Back School program for patients with chronic low back pain can have a positive effect.

A behavioral treatment for sitting and standing intolerance in a patient with chronic low back pain.

This study reports on the effectiveness of an individualized shaping treatment program for sitting and standing intolerance in a patient with chronic low back pain following a laminectomy for removal of an intradural tumor. Functional assessment of sitting and standing tolerance, observation of pain behaviors, and a self-report measure regarding the pain experience were carried out during baseline, treatment, posttreatment, and at a 6-month follow-up. By the end of the 6-week inpatient treatment, the patient was able to stand still for 25 min and to sit for 15 min. The overall pain behavior diminished significantly. These findings underscore the importance of relatively simple and cost-effective individualized behavioral programs for chronic pain patients.

Personality characteristics of the cosmetic surgical insatiable patient.

It is argued that the personality of the cosmetic surgical patient is undisturbed. Furthermore it is argued that a vast majority of these patients are very pleased with the results of the cosmetic correction. A very small percentage however is dissatisfied (although no surgical-technical mistake was made) and is urging again and again for a repetition of the procedure. The terms in which the personality of the unsatiable patient is described resemble strikingly the description of borderline personality organization. The hypothesis is put forward that the personality of the cosmetic surgical insatiable patient has a borderline organization. A clinical procedure of how to identify preoperatively the insatiable patient is proposed.

Etiologic factors in denture sore mouth syndrome.

A total of 24 patients, 19 women and 5 men, complaining of denture sore mouth was studied. In part I the following investigations were performed: (1) Mechanical factors were evaluated. (2) Temperature was measured beneath the prosthetic denture. (3) Yeast cultures were made. (4) Patch tests with possible allergens were performed on the buccal mucosa and on the skin of the back. In all these investigations there were no significant differences from the results obtained in a control group. In part II the connection between psychological factors and denture sore mouth was explored. Test results of the denture sore mouth group and a matched control group were compared. The obtained data suggest that complaining behavior concerning somatic symptoms in general, on a neurotic base, is a psychological characteristic of denture sore mouth patients.

Effects of a mass media behavioral treatment for chronic headache: a pilot study.

This article presents the results of a pilot study evaluating the efficacy of a mass media self-help behavioral treatment program for chronic headache. The program consisted of a self-help textbook, an exercise book, 10 television programs, 11 radio programs, and 3 audiocassettes with relaxation training. Approximately 15,000 headache sufferers purchased the book and relaxation tapes. A random sample of 271 respondents participated in the effect study; the pretraining and posttraining data of 164 subjects were available for analysis. Multivariate testing of the pretraining and posttraining results showed highly significant reductions in headache activity and medication intake at 4-month follow-up. A reduction of 50% or more in headache parameters and medication intake was achieved by 40% to 60% of the patients. Work absenteeism was significantly reduced. The differences between the diagnostic groups were not significant. Mass media behavioral treatment seems to be a viable treatment alternative for chronic headache and highly promising in terms of gain in quality of life, decrease in economic loss, and cost-effectiveness in health care.
