ABSTRACT This paper reports the development of a scale for assessing the quality of reports of randomised controlled trials for psychological treatments. The Delphi method was used in which a panel of 15-12 experts generated statements relating to treatment and design components of trials. After three rounds, statements with high consensus agreement were reviewed by a second expert panel and rewritten as a scale. Evidence to support the reliability and validity of the scale is reported. Three expert and five novice raters assessed sets of 31 and 25 published trials to establish scale reliability (ICC ranges from 0.91 to 0.41 for experts and novices, respectively) and item reliability (Kappa and inter-rater agreement). The total scale score discriminated between trials globally judged as good and poor by experts, and trial quality was shown to be a function of year of publication. Uses for the scale are suggested.

    • "Further exploration will be needed to clarify differences in efficacy between hypnosis and guided imagery or PMR. TA and HF rated methodological quality using procedures described in Yates et al. (2005). All methodological quality indices revealed lower scores as compared to previous studies (Eccleston, Palermo, et al., 2009; Eccleston, Williams, et al., 2009). "

    ABSTRACT: Abstract Hypnosis is regarded as an effective treatment for psychological and physical ailments. However, its efficacy as a strategy for managing chronic pain has not been assessed through meta-analytical methods. The objective of the current study was to conduct a meta-analysis to assess the efficacy of hypnosis for managing chronic pain. When compared with standard care, hypnosis provided moderate treatment benefit. Hypnosis also showed a moderate superior effect as compared to other psychological interventions for a nonheadache group. The results suggest that hypnosis is efficacious for managing chronic pain. Given that large heterogeneity among the included studies was identified, the nature of hypnosis treatment is further discussed.

    ABSTRACT: Psychological therapies (e.g. relaxation, hypnosis, coping skills training, biofeedback, and cognitive behavioural therapy) may help people manage pain and its disabling consequences. Therapies can be delivered face-to-face by a therapist, via the Internet, by telephone call, or by computer programme. This review focuses on treatments that are delivered face-to-face by a therapist. For children and adolescents there is evidence that both relaxation and cognitive behavioural therapy (treatment that helps people test and revise their thoughts and actions) are effective in reducing the intensity of pain in chronic headache, recurrent abdominal pain, fibromyalgia, and sickle cell disease immediately after treatment. Psychological therapies also have a lasting effect in reducing pain and disability for chronic headache. Fifty-six per cent of children who were treated with psychological therapies reported less pain compared with 22% of children who did not receive a psychological therapy. Anxiety was also reduced for children with headaches immediately following treatment. Psychological therapies also reduce pain and disability for children with mixed pain conditions (excluding headache) immediately following treatment. However, we did not find that any treatment effects were maintained at follow-up (between 3-12 months after the end of treatment) for children with mixed pain conditions. Psychological therapies did not produce changes in depression in children with either headache or non-headache conditions, and anxiety did not change in children with non-headache conditions receiving psychological therapies. More studies are needed to understand whether psychological therapies can improve depression and anxiety and have more lasting effects on pain and disability in other groups of young people who have chronic pain.

    ABSTRACT: In pain treatment, outcomes are generally defined by researchers and clinicians, predominantly using patient self-report. A large-scale survey of people with chronic pain found a more extensive range of treatment outcomes rated important (Turk et al., "Identifying important outcome domains for chronic pain clinical trials: an IMMPACT survey of people with pain." PAIN 2008;137:276-85) than are conventionally used (Turk et al., "Core outcome domains for chronic pain clinical trials: IMMPACT recommendations." PAIN 2003;106:337-45). We compared outcomes from 60 randomised, controlled trials of cognitive and/or behavioural treatment for persistent pain with the 19 domains rated as most important in the survey. Only 2 outcomes, physical activities and emotional well-being, were assigned comparable importance by survey respondents and clinician-researchers. Five of the 19 outcomes important to survey respondents were not measured at all, and 8 rarely. There was a positive, although modest, correlation between the methodological quality of trials and their coverage of survey respondents' outcomes. We lack measures in many areas of outcome valued by people with chronic pain, and we need to extend routine measurement of trial outcomes.
