Although several studies have illustrated the effectiveness of cognitive behavior therapy (CBT) on adult pain patients, there are few randomized controlled trials on children and adolescents. There is particularly a need for studies on pediatric patients who are severely disabled by longstanding pain syndromes. Acceptance and Commitment Therapy, as an extension of traditional CBT, focuses on improving functioning and quality of life by increasing the patient's ability to act effectively in concordance with personal values also in the presence of pain and distress. Following a pilot study, we sought to evaluate the effectiveness of an ACT-oriented intervention based on exposure and acceptance strategies and to compare this with a multidisciplinary treatment approach including amitriptyline (n=32). The ACT condition underwent a relatively brief treatment protocol of approximately 10 weekly sessions. Assessments were made before and immediately after treatment, as well as at 3.5 and 6.5 months follow-up. Prolonged treatment in the MDT group complicated comparisons between groups at follow-up assessments. Results showed substantial and sustained improvements for the ACT group. When follow-up assessments were included, ACT performed significantly better than MDT on perceived functional ability in relation to pain, pain intensity and to pain-related discomfort (intent-to-treat analyses). At post-treatment, significant differences in favor of the ACT condition were also seen in fear of re/injury or kinesiophobia, pain interference and in quality of life. Thus, results from the present study support previous findings and suggest the effectiveness of this ACT-oriented intervention for pediatric longstanding pain syndromes.

Summary:Purpose: Psychological interventions in the treatment of epilepsy have been developed and evaluated for many years but the amount of research has hardly made an impact on how epilepsy is treated. The purpose of this study was to develop and evaluate a psychological treatment program consisting of acceptance and commitment therapy (ACT) together with some behavioral seizure control technology shown to be successful in earlier research.Methods: The method consisted of a randomized controlled trial group design with repeated measures (n = 27). All participants had an EEG verified epilepsy diagnosis with drug refractory seizures. Participants were randomized into one of two conditions, ACT or supportive therapy (ST). Therapeutic effects were measured by examining changes in quality of life (SWLS and WHOQOL) and seizure index (frequency × duration). Both treatment conditions consisted of only nine hours of professional therapy distributed in two individual and two group sessions during a four-week period.Results: The results showed significant effects over all of the dependent variables for the ACT group as compared to the ST group at six-and twelve-month follow-ups.Conclusions: The results from this study suggest that a short-term psychotherapy program combined with anticonvulsant drugs may help to prevent the long-term disability that occurs from drug refractory seizures.

Although 14% to 42% of people with whiplash injuries end up with chronic debilitating pain, there is still a paucity of empirically supported treatments for this group of patients. In chronic pain management, there is increasing consensus regarding the importance of a behavioural medicine approach to symptoms and disability. Cognitive behaviour therapy has proven to be beneficial in the treatment of chronic pain. An approach that promotes acceptance of, or willingness to experience, pain and other associated negative private events (e.g. fear, anxiety, and fatigue) instead of reducing or controlling symptoms has received increasing attention. Although the empirical support for treatments emphasizing exposure and acceptance (such as acceptance and commitment therapy) is growing, there is clearly a need for more outcome studies, especially randomized controlled trials. In this study, participants (N = 21) with chronic pain and whiplash-associated disorders were recruited from a patient organization and randomized to either a treatment or a wait-list control condition. Both groups continued to receive treatment as usual. In the experimental condition, a learning theory framework was applied to the analysis and treatment. The intervention consisted of a 10-session protocol emphasizing values-based exposure and acceptance strategies to improve functioning and life satisfaction by increasing the participants' abilities to behave in accordance with values in the presence of interfering pain and distress (psychological flexibility). After treatment, significant differences in favor of the treatment group were seen in pain disability, life satisfaction, fear of movements, depression, and psychological inflexibility. No change for any of the groups was seen in pain intensity. Improvements in the treatment group were maintained at 7-month follow-up. The authors discuss implications of these findings and offer suggestions for further research in this area.

Acceptance of pain and other associated negative private experiences has received increasing attention in recent years. This approach is in stark contrast to the traditional approach of reducing or controlling symptoms of pain. The empirical support for treatments emphasizing exposure and acceptance, such as Acceptance and Commitment Therapy, is growing. However, to date, few instruments exist to assess the core processes in these types of treatments. This study describes the development and preliminary validation of the Psychological Inflexibility in Pain Scale. Principal components analysis (PCA) suggests a 2-factor solution with a total of 16 items measuring avoidance of pain and cognitive fusion with pain. Results also indicate adequate reliability and validity for the scale. Implications of these findings for clinical assessment, as well as for research on pain related disability, are discussed along with suggestions for further research in this area.

Acceptance of pain and distress has lately appeared as an important factor in determining peoples' ability to restore functioning in the presence of chronic pain. Although treatments based on cognitive behaviour therapy are beginning to incorporate acceptance strategies, there is still a lack of reliable and valid instruments to assess relevant processes in such interventions. The Chronic Pain Acceptance Questionnaire (CPAQ) was originally constructed as part of the development of an acceptance oriented treatment approach for pain patients. A revised 20-item version of the instrument with two subscales has shown adequate reliability and validity. In the present study, a Swedish translation of CPAQ was evaluated with 611 participants reporting chronic pain and symptoms of whiplash associated disorders. This study sought to further assess the psychometric properties of the instrument and to investigate its relation to another important measure of pain adjustment, the Tampa Scale of Kinesiophobia. Due to low intercorrelations with other items, item 16 was excluded. Exploratory and confirmatory factor analyses supported the previously suggested two-factor solution. Furthermore, the internal consistencies were good for the subscales (activities engagement and pain willingness) as well as the total scale. Hierarchical regression analyses illustrated strong relations with criteria variables (e.g. disability and life satisfaction). In general, the activities engagement subscale contributed more than pain willingness to the prediction of criteria variables. Furthermore, results illustrated that CPAQ explained more variance than the Tampa Scale of Kinesiophobia in pain intensity, disability, life satisfaction, and depression.

M. KATOULI, L.MELIN, M. JENSEN-WAERN, P. WALLGREN AND R. MÖ L LB Y. 1999. The effect of a dietary supplementation of zinc oxide (ZnO) on the stability of the intestinal flora and on the composition of coliforms in weaned pigs was investigated. Faecal floras were characterized by their metabolic activities and fermentative capacity (FC) using the Phene Plate generalized microplate. Coliforms were characterized by conventional enumeration and by the Phene Plate-RS plates. The latter measured FC, phenotypic diversity, persistence of each coliform strain in piglets, and similarity among the coliform populations within groups. From weaning onwards, the control pigs (n 5) were fed a basal diet ad libitum, while experimental pigs (n 5) were given the same food supplemented with 2500 ppm ZnO. Metabolic fingerprinting of faecal floras indicated marked differences between the composition of floras of treated and control pigs during the first 2 weeks post-weaning. The FC of faecal flora in both groups decreased as pigs aged, but it was significantly (P ¾ 0·0001) lower in control pigs during the first 2 weeks post-weaning. Neither the number of coliforms, nor their FC-values, differed between the groups. However, during the first 2 weeks post-weaning, there was a significant increase in both variety (P 0·019) and diversity (P ¾ 0·001) of coliforms in control pigs compared with the ZnO treated group. Homogeneity between coliform populations of piglets was high during the suckling period, indicating the presence of many identical strains among piglets. This, however, decreased in control pigs during the first 2 weeks post-weaning. Several coliform strains that colonized the gut at the early stage of the pigs' life were found to be resident in animals of both groups. It is concluded that supplementation of ZnO to weaned pigs helped to maintain the stability of the intestinal microflora and the diversity of coliforms during the first 2 weeks post-weaning, but not later, and that ZnO supplementation to creep feed should be restricted to the first 2 weeks post-weaning in veterinary practice.
