BACKGROUND A range of self-tests on body materials has become available to the general public, but the extent of their use has hardly been studied. This study examined how many people use diagnostic self-tests on body materials such as blood or urine, as well as the type of tests that are used, and factors associated with their use.

OBJECTIVES Childhood trauma (CT) has consistently been associated with neuroticism--a personality trait reflecting vulnerability to stress. However, not much is known about the impact of a history of trauma on moment-to-moment emotions and experiences in the flow of daily life. The relationship between CT and emotional reactivity to daily life stress was(More)
OBJECTIVE To test whether a disclosure intervention improves subjective health and reduces medical consumption and sick leave in somatising patients in general practice. DESIGN Non-blind randomised controlled trial. SETTING 10 general practices in the Netherlands. PARTICIPANTS 161 patients who frequently attended general practice with somatising(More)
BACKGROUND Childhood experiences profoundly affect later functioning as an adult. Family practitioners are well-placed to discover the links between childhood troubles and later somatization, depression or anxiety. OBJECTIVES We aimed to study the interrelation of somatization, depressive and anxiety disorders in frequently attending patients in general(More)
BACKGROUND In daily practice general practitioners (GPs) generally rely on their clinical judgement in assessing whether patients somatise distress. Nevertheless, conclusions derived from research on somatisation in primary care are largely based on standardised measurements of somatisation. We investigated the relation between GPs' clinical judgement of(More)
Recently, fear-avoidance models have been quite influential in understanding the transition from acute to chronic low back pain (LBP). Not only has pain-related fear been found to be associated with disability and increased pain severity, but also treatment focused at reducing pain-related fear has shown to successfully reduce disability levels. In spite of(More)
The overall aim of this study was to explore the natural course of pain-related fear during the early stage of a new low back pain episode, using a prospective case series design. Specific research questions addressed the existence of typical patterns in individual time series of pain-related fear and sequential relationships between the occurrence of(More)
Previous research supports the fear-avoidance model in explaining chronic low back pain (LBP) disability. The aims of the present study were to determine: (1) whether fear-avoidance model variables are associated already during acute stages of LBP and (2) whether (increases in) pain-related fear are associated with other patient characteristics routinely(More)
BACKGROUND In low back pain (LBP) treatment and research attention has shifted from a biomedical towards a biopsychosocial approach. Patients' LBP beliefs and attitudes were found to predict long-term outcome, and recently it has been suggested that the health care providers' ideas about LBP are also important predictors of treatment behaviour and outcome.(More)

The DSM-III-(R) definition of somatization disorder is too restrictive for use in general practice. A more comprehensive definition, the “somatic symptom index” (SSI) has shown good validity in open populations. However, a definition has to differentiate validlywithin a population of frequent attenders to be a useful diagnostic instrument in general(More)
