- Contextualization of post-surgery circumstances in terms of key behaviours and emotions related to eating is crucial for reliable screening. Disordered eating post surgery is characterized by frequent snacking and a sense of loss of control over food intake. The purpose of this study was to evaluate the psychometric properties of a short self-report questionnaire entitled Disordered Eating after Bariatric Surgery (DEBS). Results indicate that the DEBS possesses satisfactory psychometric properties in terms of reliability, validity, internal consistency and test–retest reliability. The DEBS may facilitate both systematic clinical evaluation and future research within the area of bariatric surgery.

ACT Treatment of Epilepsy : Time for a behavioral model?
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The present dissertation contributes to the understanding of behavioral treatment of epilepsy and supports the integration of medical and behavioral science to develop a treatment model to help those who suffer from drug refractory epilepsy. There is a lack of well-designed randomized controlled trials evaluating behavioral therapy for epilepsy. Medical science has contributed significantly to the development of antiepileptic drugs for seizure control, yet despite these efforts approximately 1/3 of patients suffer from recurrent seizures. The comorbidity between epilepsy and psychiatric problems is significant and quality of life is lower for those who suffer from epilepsy compared to those who suffer from other chronic illnesses. The purpose of the present dissertation is to develop and evaluate a behavioral treatment model for those who suffer from recurrent epileptic seizures and associated problems. Acceptance and commitment therapy (ACT) is compared to supportive treatment and yoga. Outcome variables are seizure frequency, seizure index (frequency * duration) and quality of life. The dissertation consists of three studies; two studies with randomized controlled group designs to evaluate treatment effects and one mediational analysis study evaluating the effect of specific therapeutic processes. The mediational analysis examines specific ACT processes such as value attainment, epilepsy related psychological flexibility and persistency in overcoming barriers. The results of the two randomized controlled trials show a significant decrease in seizure frequency and seizure index in favor of the ACT group compared to the control groups and significant changes in life quality. The results of the mediational study indicate that the evaluated processes, alone or in combination, had a mediational role in three of the four outcome variables. In conclusion, the present dissertation supports the integration of behavior and medical science to help those who suffer from epilepsy and associated problems.

- Purpose: Two studies were conducted to develop and evaluate an instrument attempting to identify and measure personal values, values attainment and believability in thoughts functioning as obstacles in living a valued life. Study one describes a content validity approach to the construction and preliminary validation of the Bull’s Eye Values Survey (BEVS), using a sample of institutionalized patients suffering from Epilepsy. Study Two investigated the psychometric properties of the BEVS with a sample of Swedish university students. Results indicate that the BEVS is sensitive to treatment effects and can differentiate between clients who receive values based interventions and those that do not. The BEVS subscales and total score appear to measure an independent dimension of psychological functioning that is negatively correlated with measures of depression, anxiety and stress and positively correlated with a measure of psychological flexibility. The BEVS also exhibits acceptable temporal stability and internal consistency. The study provides preliminary support for the BEVS as both a research and clinical tool for measuring values, valued action discrepancies and barriers to value based living.

Tidskriftsartikel (refereegranskat)abstract
- 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.Case description: Primarily, the study aims at investigating a new field, providing a basis for generating hypotheses for further research. The first aim of this initial, exploratory study was to examine if this intervention had an effect on the variables of: valued actions, psychological flexibility, and life satisfaction as well as the states of depression, anxiety and stress, for a non-clinical sample of 11 Swedish Iphone users. This was made with a quasi-experimental pretest-posttest design without control group. The second aim was to investigate how the participants experienced the intervention, as measured by a qualitative questionnaire.Discussion and evaluation: The group analyses showed that the participants increased their valued action and psychological flexibility significantly during the intervention. Furthermore, value-based actions and psychological flexibility showed small effect sizes when comparing pretest and posttest score. However, the design of the study makes it impossible to draw any certain conclusions. The qualitative questionnaire showed a general positive experience of the intervention.Conclusions: The results from the present study indicated that the intervention should be studied further. The findings also generated a number of hypotheses that could be investigated in further research.

A Contextual Behavioral Approach for Obesity Surgery Patients
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis investigates a contextual behavioral approach for obesity surgery patients. In a contextual approach a behavior is interpreted as inseparable from its current and historical context. Candidates for bariatric surgery often have a history of self-stigma, body dissatisfaction and eating for emotional relief. Despite losing a large amount of weight post surgery, psychological problems may still be present for some patients. One possible common underlying process observed in body concerns and eating patterns is experiential avoidance. Experiential avoidance is defined as; any attempt to avoid, change, or control unwanted thoughts and feelings when so doing causes harm.Though a multidisciplinary team is recommended for post-surgical care, there are few studies evaluating the psychological treatment of patients undergoing bariatric surgery. In this thesis a protocol based on Acceptance and Commitment Therapy (ACT), was developed and implemented, partly via the Internet, in a clinical setting. In an acceptance-based approach to obesity, psychological well-being is the main outcome. ACT was significantly more effective than ‘treatment as usual’ in terms of body dissatisfaction and quality of life after surgery. Both groups improved in eating disordered attitudes and behaviors. Predictions based on the underlying treatment model were also investigated. Positive treatment outcomes were found to be associated with increased psychological flexibility. Despite some methodological limitations, the results are promising and future studies should further evaluate ACT in the context of bariatric surgery.This thesis also acknowledges the need for clinical assessment tools appropriate for the bariatric surgery context. The Acceptance and Action Questionnaire for Weight (AAQ-W) is a measure of experiential avoidance, and was evaluated in the present thesis. The AAQ-W was found to be a reliable and valid measure for people undergoing bariatric surgery. Another measure, Disordered Eating in Bariatric Surgery (DEBS) was developed and evaluated. The DEBS was found to posses satisfactory psychometric properties in terms of reliability and validity. The AAQ-W and the DEBS may facilitate both systematic clinical evaluation and future research within the area of bariatric surgery.

Tidskriftsartikel (refereegranskat)abstract
- 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. The aim of this study is to evaluate the effects of acceptance and commitment therapy (ACT) for patients who underwent BS, with regard to emotional eating, body dissatisfaction and quality of life. This study is a randomized controlled trial (n = 39) with two conditions (1) ACT including two face-to-face sessions and support via an Internet application and (2) treatment as usual (TAU) comprising the standard follow-up used by the BS team. Results show that participants in the ACT condition significantly improve on eating disordered behaviors, body dissatisfaction, quality of life and acceptance for weight related thoughts and feelings, as compared to those in the TAU group. This study shows that it is possible to improve effects of BS by specifically targeting emotional eating behavior.

Tidskriftsartikel (refereegranskat)abstract
- 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.Participants were recruited at a bariatric surgery clinic during follow-up care. The evaluation of psychometric properties of AAQ-W was done by repeated measurements of reliability (n = 62), convergent validity (n = 75 and n = 178), predictive validity (n = 61), factor analysis and calculation of internal consistency (n = 178).The AAQ-W was found to have satisfactory psychometric properties. Internal consistency was high (α = .86). Results showed good stability over time (r = .77) and validity coefficients ranging from r = .36 to .71. AAQ-W scores measured six months post surgery predicted satisfaction with life, negative emotional states, emotional eating and general eating pathology measured one year post surgery. However AAQ-W measured at six months did not predict percent excess BMI Loss at one year. Factor analysis showed that a five factor solution (Food as Control, Body Acceptance, Self-Stigma, Self-Efficacy and Emotional Avoidance) might be a good fit (n = 178).This study shows that the AAQ-W appears to be a psychometrically sound measure that can be used by researchers and clinicians in the context of bariatric surgery.
