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.

Psychological functioning of morbidly obese patients after surgical treatment.

Objective: To investigate the long-term effects of surgically induced weight loss on the psychological functioning of morbidly obese patients.

Design: Comparison between preoperative and postoperative psychometric test results in a cross-sectional study.

Patients And Methods: Three psychometric tests were administered to 62 morbidly obese patients before and after surgery.

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.

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.

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.

Profile characteristics of the MPI-DLV clusters of pain patients.

This article describes an investigation into whether there are differences among the four pain patient clusters from the Multidimensional Pain Inventory-Dutch Language Version (MPI-DLV) in terms of prescribed analgesic medication, level of intelligence, and other personality characteristics (MMPI). Dysfunctional patients were distinguished by a higher level of analgesic medication intake. Patients classified as Average were marked by a marginally significant higher level of intelligence.

[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.

The relationship between spouse solicitousness and pain behavior: searching for more experimental evidence.

In this study 42 chronic back pain patients participated twice in a treadmill test. During 1 of these 2 sessions, the partner was present. Walking time, pain intensity ratings, and heart rate were measured before and after the tests.

Assessment of the components of observed chronic pain behavior: the Checklist for Interpersonal Pain Behavior (CHIP).

This article describes the development of the Checklist for Interpersonal Pain Behavior (CHIP), an observation scale which assesses overt pain behavior. The study is an extension of an earlier study in which the dimensions and components of observed chronic pain behavior were examined. A broad definition of pain behavior is chosen (interpersonal pain behavior), namely the interaction between the pain patient and his/her direct environment.

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).

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.

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.

Dimensions and components of observed chronic pain behavior.

This study is a replication of a study done by Turk et al. but under different conditions. It is an attempt to empirically examine the dimensions and components of overt and observable chronic pain behavior.

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.

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.
