Dropout Factors in Chronic Pain Management

Completed

• Conditions: Chronic Pain

• Registration Number: NCT04218227
• Lead Sponsor: University of Liege

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Influence of therapist's expertise in hypnosis	T1 (before treatment)	The influence of the therapist's expertise in hypnosis upon drop-out will be assessed by means of our database.
Link between state-financial help and drop-out	T1 (before treatment)	In Belgium, in certain cases, state will financially help patients to benefit from pain non-pharmacological treatments. We would like to understand if the benefit of state financial help influences the amount of drop-out.
Influence of pain description	T1 (before treatment)	The influence of pain description upon dropout rates will be assessed by means of a Visual Analogue Scale (VAS). Scale ranging from 0 (no pain) to 10 (worst pain).
Influence of anxiety	T1 (before treatment)	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	T1 (before treatment)	The influence of the impact of pain in individual's life, quality of social support and general activity, upon dropout will be assessed my means of the "Multidimensional Pain Index" (MPI, Kerns et al., 1985). Scale ranging from 0 (none) to 6 (a lot).
Influence of motivation	T1 (before treatment)	To understand of motivation influenced the amount of drop-out, we analysed the amount of drop-out in the "self-hypnosis/self-care motivation" group.
Influence of insomnia	T1 (before treatment)	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	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	T1 (before treatment)	The amount of drop-out between treatments group will be assessed by means of our database.
Influence of sleep difficulties	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	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	T1 (before treatment)	The influence of pain disability upon will be assessed by means of the "Pain Disability Index" (PDI, Tait et al., 1990). Scale ranging from 0 (no difficulties) to 10 (a lot of difficulties).
Influence of attitudes and beliefs about pain	T1 (before treatment)	The influence of the attitudes and beliefs about pain upon dropout will be assessed my means of the "Survey of Pain Attitudes" (SOPA, Jensen \& Karoly, 1987). Scale ranging from 0 (totally wrong) to 10 (totally right).
Influence of quality of life	T1 (before treatment)	The influence of quality of life upon dropout will be assessed by means of the "SF-36"(Ware et al., 1988). Each item is balanced to obtain a score between 0 (worst quality) to 100 (maximum quality).
Amount of dropout between treatment groups	T1 (before treatment)	The amount of drop-out between treatments group will be assessed by means of our database.
