BackgroundIn the field of bariatric surgery, research on symptoms of adult attention deficit hyperactivity disorder (ADHD) and their interrelationships with other psychological risk factors such as depression and anxiety is scarce. The symptoms of adult ADHD seem to be common in the obese population, but they are rarely investigated before bariatric surgery. ADHD-related symptoms such as impulsivity have at the same time been identified as potential risk factors for less successful weight loss among bariatric surgery patients. The aims of the current study were to screen for symptoms of adult ADHD and to investigate their relationships with other psychological risk factors.MethodsCandidates for bariatric surgery (N = 187) were anonymously screened for symptoms of anxiety, depression, and adult ADHD, in addition to disordered eating patterns, by means of questionnaires. The relations between these symptoms were investigated.ResultsIn the current sample, 10% of patients screened positively for adult ADHD, and the symptoms of adult ADHD were significantly correlated with those of anxiety, depression, and disordered eating.ConclusionsThe results show that adult ADHD is more common in this clinical group than in the general population (4%) and that adult ADHD is associated with disordered eating patterns, depression, and anxiety. Further prospective research, using multivariate analysis, is needed to investigate whether the symptoms of adult ADHD, and their interaction with anxiety, depression, or disordered eating, may possibly constitute a risk factor in terms of difficulties in adhering to the post-surgery regime and its potential unfavorable outcome.

Cognitive behaviour therapy (CBT) can reduce tinnitus distress but is not available for most patients. Therapist guided, internet-based CBT (ICBT) increase availability and has been shown to be effective. However, the initial positive results need to be replicated in larger samples, and treatment dropout has not been thoroughly studied. Moreover, it has not been evaluated if a low-intensity version of ICBT without therapist contact could be an alternative for patients who do not need or are able to manage the full ICBT-program. This study evaluated two parallel interventions delivered in regular care: ICBT for tinnitus distress (n = 293) and a low-intensity version of ICBT (n = 81) for patients with lower levels of tinnitus distress. We also explored predictors of dropout from ICBT and if dropout influences outcome. Tinnitus Reaction Questionnaire (Wilson, Henry, Bowen, & Haralambous, 1991) was used as the primary outcome. Secondary outcomes were measures of depression, anxiety, sleep, and sound sensitivity. Significant reductions following ICBT were found on all measures after treatment and also at a three-month follow-up. Patients receiving low-intensity ICBT showed a significant reduction in distress, even when they had low levels of distress initially. Treatment dropout was preceded by an increase in days spent at each treatment step but not by an increased distress. Early dropout was related to worse outcome. ICBT can be used in a regular clinical setting to reduce tinnitus distress. Early dropouts may need additional management. For help-seeking patients with lower distress, a low-intensity version of ICBT can be used.

Interformat Reliability of Digital Psychiatric Self-Report Questionnaires: A Systematic Review

Sven Alfonsson; Pernilla Maathz; Timo Hursti

Background Research on Internet-based interventions typically use digital versions of pen and paper self-report symptom scales. However, adaptation into the digital format could affect the psychometric properties of established self-report scales. Several studies have investigated differences between digital and pen and paper versions of instruments, but no systematic review of the results has yet been done. Objective This review aims to assess the interformat reliability of self-report symptom scales used in digital or online psychotherapy research. Methods Three databases (MEDLINE, Embase, and PsycINFO) were systematically reviewed for studies investigating the reliability between digital and pen and paper versions of psychiatric symptom scales. Results From a total of 1504 publications, 33 were included in the review, and interformat reliability of 40 different symptom scales was assessed. Significant differences in mean total scores between formats were found in 10 of 62 analyses. These differences were found in just a few studies, which indicates that the results were due to study effects and sample effects rather than unreliable instruments. The interformat reliability ranged from r=.35 to r=.99; however, the majority of instruments showed a strong correlation between format scores. The quality of the included studies varied, and several studies had insufficient power to detect small differences between formats. Conclusions When digital versions of self-report symptom scales are compared to pen and paper versions, most scales show high interformat reliability. This supports the reliability of results obtained in psychotherapy research on the Internet and the comparability of the results to traditional psychotherapy research. There are, however, some instruments that consistently show low interformat reliability, suggesting that these conclusions cannot be generalized to all questionnaires. Most studies had at least some methodological issues with insufficient statistical power being the most common issue. Future studies should preferably provide information about the transformation of the instrument into digital format and the procedure for data collection in more detail.

Motivation and Treatment Credibility Predicts Dropout, Treatment Adherence, and Clinical Outcomes in an Internet-Based Cognitive Behavioral Relaxation Program: A Randomized Controlled Trial

Sven Alfonsson; Erik Olsson; Timo Hursti

Background In previous research, variables such as age, education, treatment credibility, and therapeutic alliance have shown to affect patients’ treatment adherence and outcome in Internet-based psychotherapy. A more detailed understanding of how such variables are associated with different measures of adherence and clinical outcomes may help in designing more effective online therapy. Objective The aims of this study were to investigate demographical, psychological, and treatment-specific variables that could predict dropout, treatment adherence, and treatment outcomes in a study of online relaxation for mild to moderate stress symptoms. Methods Participant dropout and attrition as well as data from self-report instruments completed before, during, and after the online relaxation program were analyzed. Multiple linear and logistical regression analyses were conducted to predict early dropout, overall attrition, online treatment progress, number of registered relaxation exercises, posttreatment symptom levels, and reliable improvement. Results Dropout was significantly predicted by treatment credibility, whereas overall attrition was associated with reporting a focus on immediate consequences and experiencing a low level of intrinsic motivation for the treatment. Treatment progress was predicted by education level and treatment credibility, whereas number of registered relaxation exercises was associated with experiencing intrinsic motivation for the treatment. Posttreatment stress symptoms were positively predicted by feeling external pressure to participate in the treatment and negatively predicted by treatment credibility. Reporting reliable symptom improvement after treatment was predicted by treatment credibility and therapeutic bond. Conclusions This study confirmed that treatment credibility and a good working alliance are factors associated with successful Internet-based psychotherapy. Further, the study showed that measuring adherence in different ways provides somewhat different results, which underscore the importance of carefully defining treatment adherence in psychotherapy research. Lastly, the results suggest that finding the treatment interesting and engaging may help patients carry through with the intervention and complete prescribed assignments, a result that may help guide the design of future interventions.

U-CARE: Internet-based stepped care with interactive support and cognitive behavioral therapy for reduction of anxiety and depressive symptoms in cancer - a clinical trial protocol

Susanne Mattsson; Sven Alfonsson; Maria E. Carlsson; Peter Nygren; Erik Olsson; Birgitta Johansson

BackgroundApproximately 20–30% of patients with cancer experience a clinically relevant level of emotional distress in response to disease and treatment. This in itself is alarming but it is even more problematic because it is often difficult for physicians and nurses to identify cancer patients who experience clinically relevant levels of anxiety and depression symptoms. This can result in persistent distress and can cause human suffering as well as costs for individuals and to the community.MethodsApplying a multi-disciplinary and design-oriented approach aimed at attaining new evidence-based knowledge in basic and applied psychosocial oncology, this protocol will evaluate an intervention to be implemented in clinical practice to reduce cancer patient anxiety and depression. A prospective randomized design will be used.The overarching goal of the intervention is to promote psychosocial health among patients suffering from cancer by means of self-help programmes delivered via an Internet platform. Another goal is to reduce costs for individuals and society, caused by emotional distress in response to cancer.Following screening to detect levels of patient distress, patients will be randomized to standard care or a stepped care intervention. For patients randomized to the intervention, step 1 will consist of self-help material, a chat forum where participants will be able to communicate with each other, and a Frequently Asked Questions (FAQ) section where they can ask questions and get answers from an expert. Patients in the intervention group who still report symptoms of anxiety or depression after access to step 1 will be offered step 2, which will consist of cognitive behavioral therapy (CBT) administered by a personal therapist. The primary end point of the study is patients’ levels of anxiety and depression, evaluated longitudinally during and after the intervention.DiscussionThere is a lack of controlled studies of the psychological and behavioral processes involved in this type of intervention for anxiety and depressive disorders. Since anxiety and depressive symptoms are relatively common in patients with cancer and the availability of adequate support efforts is limited, there is a need to develop evidence-based stepped care for patients with cancer, to be delivered via the Internet.Trial registrationClinicalTrials.gov Identifier: NCT01630681

Group behavioral activation for patients with severe obesity and binge eating disorder: a randomized controlled trial.

Sven Alfonsson; Thomas Parling; Ata Ghaderi

The aim of the present study was to assess whether behavioral activation (BA) is an efficacious treatment for decreasing eating disorder symptoms in patients with obesity and binge eating disorder (BED). Ninety-six patients with severe obesity and BED were randomized to either 10 sessions of group BA or wait-list control. The study was conducted at an obesity clinic in a regular hospital setting. The treatment improved some aspects of disordered eating and had a positive effect on depressive symptoms but there was no significant difference between the groups regarding binge eating and most other symptoms. Improved mood but lack of effect on binge eating suggests that dysfunctional eating (including BED) is maintained by other mechanisms than low activation and negative mood. However, future studies need to investigate whether effects of BA on binge eating might emerge later than at post-assessment, as in interpersonal psychotherapy for bulimia nervosa.

Is age a better predictor of weight loss one year after gastric bypass than symptoms of disordered eating, depression, adult ADHD and alcohol consumption?

Sven Alfonsson; Magnus Sundbom; Ata Ghaderi

INTRODUCTION Findings regarding psychological risk factors for low weight loss after bariatric surgery have been inconsistent. The association between gender and weight outcome is unclear while younger age has been consistently shown to be associated with better weight outcome. The aim of this study was to analyze the interactions between gender and age on the one hand and symptoms of disordered eating, depression, adult ADHD and alcohol consumption on the other hand in regard to weight loss after gastric bypass. METHODS Bariatric surgery patients were recruited and asked to fill out self-report questionnaires regarding behavioral risk factors before and twelve months after surgery. Data from one hundred and twenty-nine patients were analyzed. RESULTS After controlling for age, no psychological variable measured prior to surgery could predict weight loss after twelve months. After surgery, there was an interaction effect between age, gender and specific eating disorder symptoms. Specifically, loss of control over eating was a risk factor for low weight loss among older, but not among younger, female participants. Symptoms of adult ADHD were associated with elevated alcohol consumption after surgery. DISCUSSION These results indicate that age and gender may moderate the effects of potential risk factors for inferior weight outcome. This interaction could potentially be one of the reasons behind the mixed findings in this field. Thus, there are important gender differences in the bariatric population that should be considered. The present study is the first to show that symptoms of adult ADHD may not be a risk factor for inferior weight loss but for alcohol risk consumption after gastric bypass.

Measuring Use of Health-Related Support on the Internet: Development of the Health Online Support Questionnaire (HOSQ)

Susanne Mattsson; Erik Olsson; Sven Alfonsson; Birgitta Johansson; Maria Carlsson

Background Social support plays an important role for the perceived health in people with health problems and chronic diseases. Provision of different kinds of support during the disease trajectory is crucial for many people. Online support is ubiquitous and represents a promising modality for people with chronic diseases. There are no existing instruments that measure various aspects of online support. Objective The objective of this study was to create a generic questionnaire regarding health-related support online that can be applied to people with various health problems and illnesses. Additionally, we wanted to test the questionnaire in a cancer population to assess its adequacy in the context of severe disease. Methods Initial items for the Health Online Support Questionnaire (HOSQ) were inspired by sociologist James House regarding social support. An exploratory factor analysis was conducted in healthy persons or with minor health problems (n=243) on 31 initial items. The scale was reduced to 18 items and the internal consistency and reliability of the scale was examined along with content validity. Further validation was conducted by a confirmatory analysis on the 18-item scale in a cancer population (n=215). In addition, data on demographics, health problems experienced, and Internet use were collected. Results The exploratory factor analysis on the final 18-item scale resulted in 2 factors. After scrutinizing the content, these factors were labeled “reading” and “interacting” and they demonstrated good internal consistency (Cronbach alphas .88 and .77, respectively). The factors were confirmed in the cancer population. The response pattern revealed expected differences both between the interaction and reading scales and according to age, gender, education, and health problems thereby supporting the validity of the HOSQ. Conclusions The HOSQ may be a reliable and valid instrument for measuring the use of online support for people with health problems, but the results ought to be replicated in more studies to confirm the results for different diagnoses. If the results of this study are corroborated by future studies, the HOSQ may be used as a basis for the development of different forms of support on the Internet.

Differences in motivation and adherence to a prescribed assignment after face-to-face and online psychoeducation: an experimental study

Sven Alfonsson; Karin Johansson; Jonas Uddling; Timo Hursti

BackgroundAdherence to treatment homework is associated with positive outcomes in behavioral psychotherapy but compliance to assignments is still often moderate. Whether adherence can be predicted by different types of motivation for the task and whether motivation plays different roles in face-to-face compared to online psychotherapy is unknown. If models of motivation, such as Self-determination theory, can be used to predict patients’ behavior, it may facilitate further research into homework promotion. The aims of this study were, therefore, to investigate whether motivation variables could predict adherence to a prescribed assignment in face-to-face and online interventions using a psychotherapy analog model.MethodsA total of 100 participants were included in this study and randomized to either a face-to-face or online intervention. Participants in both groups received a psychoeducation session and were given an assignment for the subsequent week. The main outcome measurements were self-reported motivation and adherence to the assignment.ResultsParticipant in the face-to-face condition reported significantly higher levels of motivation and showed higher levels of adherence compared to participants in the online condition. Adherence to the assignment was positively associated with intrinsic motivation and intervention credibility in the whole sample and especially in the online group.ConclusionsThis study shows that intrinsic motivation and intervention credibility are strong predictors of adherence to assignments, especially in online interventions. The results indicate that intrinsic motivation may be partly substituted with face-to-face contact with a therapist. It may also be possible to identify patients with low motivation in online interventions who are at risk of dropping out. Methods for making online interventions more intrinsically motivating without increasing external pressure are needed.Trial registrationclinicaltrials.gov NCT02895308.
