Abstract:About 18% of the adults in the Netherlands are suffering from chronic pain. 1 In the case of chronic pain it is most of the time not known where the complaints are caused by. The pain does not have a function in recovery and is often interfering with daily activities. 2 There are two types of patients; patients that avoid activity because of the pain and patients that deny the pain and have an overactive behavior pattern. 3,4 Over the last decades a lot of different treatments have developed2, but there is also a group of patients that cannot be relieved from pain by these treatments. These patients can be considered for Acceptance Commitment Therapy. (ACT) 5 However, little is known about the factors that influence the effect of this treatment. We researched the effect of the treatment with ACT. First we took a look at the positive effects of the treatment, where they there? Secondly we sought for correlations between sex and age and the treatment effect. At last we examined if avoidance or overactive behavior influenced the effect of the treatment. The constructs have been operationalized by the use of questionnaires. We used descriptive statistics and we performed a paired t-test and a repeated measures ANOVA. The moderating and mediating factors have been analyzed by two models that use linear regression. From our results it turned out that treatment with ACT has a reduction effect on pain interference. This means that ACT is an effective treatment for chronic pain. Unfortunately, our research into the influence of sex and/or age on the success of the treatment did not come up with significant results. The analysis of mediation did give just a few significant results. We found a reducing effect of catastrophizing on avoidance, a reducing effect of minimalizing on overactivity and a reducing effect of avoidance on the difference in pain interference, when correcting for the direct path. The analysis could be more powerful when it would be performed on larger scale, this way we could see if there really is no correlation between the constructs. Results could be placed in the situation more properly and there could have been more descriptive statistics about the patient population. Because ACT is a form of cognitive behavior therapy, the success of the treatment is largely dependent on the different professionals and how they give treatment. There could be more documentation about the staff. There is also a possibility of bias through missing data. Also, patients can be focused on their pain when filling in the questionnaire, this could lead to distorted view on the severity of the pain.
