Objective: The objective was to (i) assess the long-term cost-effectiveness of acceptance and commitment therapy (ACT), a workplace dialog intervention (WDI), and ACT+WDI compared to treatment as usual (TAU) for common mental disorders and (ii) investigate any differences in cost-effectiveness between diagnostic groups.

Methods: An economic evaluation from the healthcare and limited welfare perspectives was conducted alongside a randomized clinical trial with a two-year follow-up period. Persons with common mental disorders receiving sickness benefits were invited to the trial.

Background: Chronic pain and mental disorders are common reasons for long term sick leave. The study objective was to evaluate the efficacy of a multidisciplinary assessment and treatment program including acceptance and commitment therapy (TEAM) and stand-alone acceptance and commitment therapy (ACT), compared with treatment as usual (Control) on health outcomes in women on long-term sick leave.

Method: Participants ( = 308), women of working age on long term sick leave due to musculoskeletal pain and/or common mental disorders, were randomized to TEAM ( = 102), ACT ( = 102) or Control ( = 104).

Pain is reported as one of the most common and difficult symptoms for children and adolescents with cancer to cope with. Pain catastrophizing has been identified as a process clearly related to pain intensity and disability. The Pain Catastrophizing Scale for Children (PCS-C) has been validated in several languages and populations but remains to be validated in pediatric oncology.

Objectives: Pain is reported as one of the most common and burdensome symptoms for children with cancer. Pain catastrophizing is clearly related to pain intensity and disability. Catastrophizing in parents is associated with both child functioning and parent distress.

Purpose: Common mental disorders (CMDs) and musculoskeletal disorders are highly prevalent in the population and cause significant distress and disability, and high costs to society. The main objective of this systematic review and meta-analysis was to examine the outcome and comparative effectiveness of psychological interventions in reducing sickness absence (SA) due to CMDs or musculoskeletal disorders, compared to a waitlist control group, usual care or another clinical intervention.

Methods: We reviewed 3515 abstracts of randomized controlled trials published from 1998 to 2017.

Objective: The aim of this study was to evaluate cost-effectiveness of Acceptance and Commitment Therapy (ACT) and workplace dialogue intervention (WDI), both as stand-alone interventions and in combination, compared with treatment as usual (TAU), for employees on sickness absence with mental disorders.

Methods: Employees (n = 352, 78.4% females) on sickness absence were randomized to one of four groups.

Background: Children and adolescents with cancer report pain as one of their most recurrent and troublesome symptoms throughout the cancer trajectory. Pain evokes psychological distress, which in turn has an amplifying effect on the pain experience. Acceptance-based interventions for experimentally induced acute pain predict increased pain tolerance, decreased pain intensity and decreased discomfort of pain.

Objectives: Children with cancer often suffer from pain. Pain is associated with psychological distress, which may amplify the pain experience. In chronic pain, it has been shown that psychological acceptance is helpful for both adults and children.

Objectives: Pain is one of the most frequent and burdensome symptoms for children with cancer. Psychological acceptance has been shown to be beneficial in chronic pain. Acceptance-based interventions for experimentally induced pain have been shown to predict increased pain tolerance and decreased pain intensity.

Background: Cognitive behavior therapy (CBT) is considered effective for chronic pain, but little is known about active treatment components. Although acceptance correlates with better health outcomes in chronic pain patients, no study has examined its mediating effect in an experimental design.

Purpose: The aim of the present study is to investigate acceptance as a mediator in acceptance and commitment therapy (ACT), a third wave CBT intervention, for chronic pain.

Background: Valid measures capturing underlying psychological processes post surgery for obesity are needed to help identify important clinical targets and develop psychosocial interventions in conjunction with surgery. The Acceptance and Action Questionnaire for Weight (AAQ-W) measures experiential avoidance and has never been evaluated in a bariatric surgery population.

Method: Participants were recruited at a bariatric surgery clinic during follow-up care.

Bariatric surgery (BS) is rated as the best evidence based treatment for obesity with regard to weight loss and maintenance of weight loss evaluated to date. Although BS interventions are effective, 20-30% of BS patients start to regain weight within 24 months. Emotional eating is a behavior pattern which has been found to predict poor outcome.

Background: An intervention, consisting of an ACT-based smartphone-application and a web-based psychoeducation, has been developed. The smartphone-application, together with the psychoeducation, aims to function as a self-help intervention for living consistently with one's values. The study is an exploratory investigation of this new smartphone-based tool.

Objective: The aim of this study was to compare 2 self-help-based interventions; a coping-oriented approach, applied relaxation (AR) and an acceptance-oriented approach, acceptance and commitment therapy (ACT), for persons with chronic pain.

Method: This study is a randomized control trial (N=90) with a mixed between-within participants design with repeated measures. Interventions in both conditions comprised an initial face-to-face session, a 7-week manual-based self-help intervention including weekly therapist telephone support and a concluding face-to-face session.

Skinner described behavior analysis as the field of values and purpose. However, he defined these concepts in terms of a history of reinforcement and failed to specify whether and how human and nonhuman values might differ. Human values have been seen as theoretically central within a number of nonbehavioral traditions in psychology, including humanism and positive psychology.

The present study examined the mediators of change accounting for outcomes of a previously published study on acceptance and commitment therapy for the self-management of epilepsy and its life restricting impact. Conducted with 27 poor South Africans, a 9-h ACT protocol that included seizure management methods was shown to greatly reduce epileptic seizures and to increase quality of life over the next year as compared to an attention placebo control. A series of bootstrapped non-parametric multiple mediator tests showed that pre to follow-up changes in: seizures, quality of life, and well-being outcomes were mediated to a degree by ACT process measures of epilepsy-related acceptance or defusion, values attainment, persistence in the face of barriers, or their combination.

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).

The aim of the present study was to provide information about factors related to long-duration pain (LDP) (>3 months), sick leave (SL) and long sick leave (LSL) (>3 months) among staff in the community health services. The specific research question was: To what extent do data on activity, physical function, pain severity, psychological/cognitive factors, expectations of LDP, expectations to be working within 6 months and work satisfaction predict LDP, SL and LSL respectively? Logistic regression analyses were used to test predicted membership in the groups LDP, SL and LSL. In this context prediction refers to statistical prediction only, due to the cross-sectional design.
