Objective: To investigate if general practitioners (GPs) with a higher workload are less inclined to encourage their patients to disclose psychological problems, and are less aware of their patients' psychological problems.

Methods: Data from 2095 videotaped consultations from a representative selection of 142 Dutch GPs were used. Multilevel regression analyses were performed with the GPs' awareness of the patient's psychological problems and their communication as outcome measures, the GPs' workload as a predictor, and GP and patient characteristics as confounders.

Objectives And Methods: More than 7,100 electronic diaries from 80 patients with chronic pain (mean: 89.3, range 30-115) entered multilevel analyses to establish the statistical prediction of disability by pain intensity and by psychological functioning (fear avoidance, cognitive, and spousal pain responses). We also tested the differences between pre-chronic, recently chronic, and persistently chronic pain in the prediction of disability (impaired physical and mental capacity, pain interference with activities, immobility due to pain).

Objectives And Methods: Electronic momentary assessment was employed to substantiate the relevance of psychological functioning in chronic pain. More than 7,100 electronic diaries from 80 patients with varying IASP classified types of chronic pain served to investigate to what extent fear-avoidance, cognitive and spousal solicitous and punishing pain responses explained fluctuations in pain intensity and whether patients with pre-chronic, recently chronic and persistently chronic pain differed in this regard.

Results: Psychological pain responses explained 40% of the total variance in pain intensity: almost 24% concerned pain variance that occurred between the CPD patients and 16% pertained to pain variance due to momentary differences within these patients.

Objective: The aims of this study were to examine health problems of children (4-12 years old at the time of the disaster) and adolescents (13-18 years old at the time of the disaster) before and after exposure to a fireworks disaster in the Netherlands (May 2000), to compare these health problems with a control group, and to identify risk factors for postdisaster psychological problems.

Method: Because the electronic medical records of family practitioners were used, longitudinal monitoring of health problems from 1 year predisaster until 2 years postdisaster for both victims (N=1,628) and controls (N=2,856) was possible. Health problems were classified according to the International Classification of Primary Care.

Background: Quality of care from the perspective of users is increasingly used in evaluating health care performance. Going beyond satisfaction studies, quality of care from the users' perspective is conceptualised in two dimensions: the importance users attach to aspects of care and their actual experience with these aspects. It is well established that health care systems differ in performance.

Allowing consumers greater choice of health plans is believed to be the key to high quality and low costs in social health insurance. This study investigates consumer preferences (361 persons, response rate 43%) for hypothetical health plans which differed in 12 characteristics (premium, deductibles, no-claim discount, extension of insurance and financial services, red tape involved, medical help-desk, choice of family physicians and hospitals, dental benefits, physical therapy benefits, benefits for prescription drugs and homeopathy). In 90% the health plan with the most attractive characteristics was preferred, indicating a predominantly rational kind of choice.

Objective: To promote managed competition in Dutch health insurance, the insured are now able to change health insurers. They can choose a health insurer with a low flat-rate premium, the best supplementary insurance and/or the best service. As we do not know why people prefer one health insurer to another, we investigated their reasons for selecting their health insurer and assessed the importance of the supplementary benefit package and the flat-rate premium.
