简要总结
Chronic pain concernes one in four adults in Belgium. Because of the psychological and social repercussions, a biopsychosocial approach is necessary in order to improve the quality of life chronic pain patients. Non-pharmacological techniques such as hypnosis, self-care learning, music-therapy and psycho-education are gaining more and more interest in the scientific field. However, a major problem in clinical research is patient dropout. To our knowledge, no study has investigated dropout rates in hypnosis clinical research. The aim of this study is, therefore, to better understand the predictors of dropout in several non-pharmacological treatments in chronic pain management.

The influence of anxiety upon dropout will be assessed by means of the subtest "anxiety" of the Hospital Anxiety and Depression Scale (HADS, Zigmond \& Snaith, 1983). Scale ranging from 0 (never) to 4 (always).
Influence of the impact of pain

The influence of the severity of insomnia upon dropout will be assessed by means of the "Insomnia Severity Index" (Morin et al., 2001). Scale ranging from 0 (none) to 4 (very severe).
Influence of locus of control
时间窗: T1 (before treatment)
The influence of the locus of control upon dropoout will be assessd my means og the "Multidimensional Health Locus of Control" (MHLC, Wallston et al., 1978). Scale ranging from 1 (no agreement) to 4 (agreement).
Amount of drop-out
时间窗: T1 (before treatment)
The amount of drop-out between treatments group will be assessed by means of our database.
Influence of sleep difficulties
时间窗: T1 (before treatment)
The influence of sleep difficulties upon dropout rates will be assessed by means of a Visual Analogue Scale (VAS). Scale ranging from 0 (no sleep difficulties) to 10 (worst sleep difficulties).
Influence of depression
时间窗: T1 (before treatment)
The influence of depression upon dropout will be assessed by means of the subtest "anxiety" of the Hospital Anxiety and Depression Scale (HADS, Zigmond \& Snaith, 1983). Scale ranging from 0 (never) to 4 (always).
Influence of pain disability
时间窗: T1 (before treatment)
