Abstract Background Cognitive behavior therapy (CBT) is widely regarded as an effective treatment for obsessive compulsive disorder (OCD), but access to CBT therapists is limited. Internet-based CBT (ICBT) with therapist support is a way to increase access to CBT but has not been developed or tested for OCD. The aim of this study was to evaluate ICBT for OCD. Method An open trial where patients (N = 23) received a 15-week ICBT program with therapist support consisting of psychoeducation, cognitive restructuring and exposure with response prevention. The primary outcome was the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), which was assessed by a psychiatrist before and immediately after treatment. Secondary outcomes were self-rated measures of OCD symptoms, depressive symptoms, general functioning, anxiety and quality of life. All assessments were made at baseline and post-treatment. Results All participants completed the primary outcome measure at all assessment points. There were reductions in OCD symptoms with a large within-group effect size (Cohen's d = 1.56). At post-treatment, 61% of participants had a clinically significant improvement and 43% no longer fulfilled the diagnostic criteria of OCD. The treatment also resulted in statistically significant improvements in self-rated OCD symptoms, general functioning and depression. Conclusions ICBT with therapist support reduces OCD symptoms, depressive symptoms and improves general functioning. Randomized trials are needed to confirm the effectiveness of this new treatment format. Trial Registration ClinicalTrials.gov: NCT01348529

Abstract Background Irritable Bowel Syndrome (IBS) is highly prevalent and is associated with a substantial economic burden. Cognitive behavior therapy (CBT) has been shown to be effective in treating IBS. The aim of this study was to evaluate the cost-effectiveness of a new treatment alternative, internet-delivered CBT based on exposure and mindfulness exercises. Methods Participants (N = 85) with IBS were recruited through self-referral and were assessed via a telephone interview and self-report measures on the internet. Participants were randomized to internet-delivered CBT or to a discussion forum. Economic data was assessed at pre-, post- and at 3-month and 1 year follow-up. Results Significant cost reductions were found for the treatment group at $16,806 per successfully treated case. The cost reductions were mainly driven by reduced work loss in the treatment group. Results were sustained at 3-month and 1 year follow-up. Conclusions Internet-delivered CBT appears to generate health gains in IBS treatment and is associated with cost-savings from a societal perspective.

Objective: Therapist guided Internet-Delivered Cognitive Behavior Therapy (ICBT) is effective, but as in traditional CBT, not all patients improve, and clinicians generally fail to identify them early enough. We predict treatment failure in 12-week regular care ICBT for Depression, Panic disorder and Social anxiety disorder, using only patients' weekly symptom ratings to identify when the accuracy of predictions exceed 2 benchmarks: (a) chance, and (b) empirically derived clinician preferences for actionable predictions. Method: Screening, pretreatment and weekly symptom ratings from 4310 regular care ICBT-patients from the Internet Psychiatry Clinic in Stockholm, Sweden was analyzed in a series of regression models each adding 1 more week of data. Final score was predicted in a holdout test sample, which was then categorized into Success or Failure (failure defined as the absence of both remitter and responder status). Classification analyses with Balanced Accuracy and 95% Confidence intervals was then compared to predefined benchmarks. Results: Benchmark 1 (better than chance) was reached 1 week into all treatments. Social anxiety disorder reached Benchmark 2 (>65%) at week 5, whereas Depression and Panic Disorder reached it at week 6. Conclusions: For depression, social anxiety and panic disorder, prediction with only patient-rated symptom scores can detect treatment failure 6 weeks into ICBT, with enough accuracy for a clinician to take action. Early identification of failing treatment attempts may be a viable way to increase the overall success rate of existing psychological treatments by providing extra clinical resources to at-risk patients, within a so-called Adaptive Treatment Strategy. What is the public health significance of this article?: The study suggests that clinically actionable predictions of treatment failure in ongoing therapist guided Internet-Delivered Cognitive Behavior Therapy can be made halfway through a 12-week long treatment using patient ratings on symptom severity as the only predictor. This means that such predictions could be performed with very simple methods, which would enable clinicians to monitor progress and use an adaptive treatment strategy for patients who are not benefitting from treatment.

Objectives: To evaluate feasibility and preliminary effects of a new group treatment manual for adults with ADHD and to explore adherence to treatment and its relation to outcome. Method: Eighteen adults with ADHD recruited from neuropsychiatric units in Stockholm underwent a 14-week program including combined cognitive and dialectical behavior therapy. Assessments were made at baseline, posttreatment, and follow-up, at one and six months after treatment end. Primary outcome measure was the Adult ADHD Self Report Scale version 1.1. Results/Conclusion: ADHD symptoms significantly decreased (d = 1.29) and remained stable for 6 months. Measures of depression, perceived stress, and anxiety were also significantly reduced. Attendance and patient satisfaction was high. Use, comprehension, and perceived benefit of treatment components varied from medium to high. Total use of treatment components was, in general, positively correlated with favorable outcome. The current combination of treatment components may be a valuable addition to available treatments in psychiatric care. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a common and debilitating inflammatory dermatological disorder and is marked by itch and inflamed skin. Scratching, sleep loss, and avoidance of situations associated with more AD symptoms are central hypothesized mechanisms that perpetuate the disorder and cause reduced quality of life. We developed an exposure-based cognitive behavioral treatment (CBT) that entailed mindfulness practice as a means to increase tolerance for aversive experiences during exposure. The aim of the present study was to test the treatment's acceptability and preliminary efficacy in adults with AD. We used an uncontrolled pretest-posttest design and recruited participants (N = 9) from a university hospital dermatological clinic. The treatment comprised 10 weekly sessions over 10 weeks and assessments of AD symptoms as well as psychiatric symptoms and quality of life were conducted at baseline, posttreatment and 6-month follow-up. The results showed significant and large baseline to posttreatment improvements on self-reported measures of AD symptoms (p =.020) and general anxiety (p =.005), but there was no significant improvement in depression or quality of life. Treatment satisfaction was high and a majority of participants (67%) completed the treatment. We conclude that exposure-based CBT for adult AD can be feasible, acceptable, and potentially efficacious. [ABSTRACT FROM AUTHOR]

- Abstract
Obsessive-compulsive disorder (OCD) is a common and disabling disorder. Although evidence-based psychological treatments exists, such as cognitive behavior therapy (CBT), the cost-effectiveness of CBT has not been properly investigated. In this trial, we used health economic data from a recently conducted randomized controlled trial, where 101 OCD patients were allocated to either internet-based CBT (ICBT) or control condition (online support therapy). We analyzed treatment effectiveness in relation to costs, using both a societal- (including all direct and indirect costs) and a health care unit perspective (including only the direct treatment costs). Bootstrapped net benefit regression analyses were also conducted, comparing the difference in costs and effects between ICBT and control condition, with different willingness-to-pay scenarios. Results showed that ICBT produced one additional remission for an average societal cost of $931 and this figure was even lower ($672) when narrowing the perspective to treatment costs only. The cost-utility analysis also showed that ICBT generated one additional QALY to an average price of $7186 from a societal perspective and $4800 when just analyzing the treatment costs. We conclude that ICBT is a cost-effective treatment and the next step in this line of research is to compare the cost-effectiveness of ICBT with face-to-face CBT. [ABSTRACT FROM AUTHOR]

- Abstract
Cognitive behavior therapy (CBT) is an effective treatment for OCD when delivered face-to-face, in group-format and also via the internet. However, despite overall large effect sizes, a considerable amount of the patients relapse. One intervention that has the potential to reduce these relapse rates is booster programs, but if booster program is a cost-effective method of preventing relapse is still unknown. We used health economical data from a recent randomized controlled trial, where patients who had undergone an internet-based CBT were randomly allocated to receive an additional booster program. Assessment points were 4-, 7-, 12- and 24-month. Health economical data were primarily analyzed using a societal perspective. Results showed that the booster program was effective in preventing relapse, and the cost of one avoided relapse was estimated to $1066–1489. Cost-effectiveness acceptability curves showed that the booster program had a 90% probability of being cost-effective given a willingness to pay of $1000–1050 the first year, but this figure grew considerably after two years ($2500–5500). We conclude that internet-based booster programs are probably a cost-effective alternative within one-year time frame and that more treatment may be needed to maintain adequate cost-effectiveness up to two years.

- Abstract
Internet-based cognitive behavior therapy (ICBT) for obsessive–compulsive disorder (OCD) has shown efficacy in randomized trials but many patients do not respond to the treatment, we therefore need to find predictors and moderators of treatment response. In this study, we analyzed predictors of ICBT response using both post-treatment as well as 24-month outcome data. As half of the participants were randomized to receive an Internet-based booster program as an adjunct to ICBT, we also investigated moderators of ICBT with or without booster. Results showed that more severe baseline OCD symptoms predicted worse end state outcome but also higher degree of change. Furthermore, high degree of working alliance predicted better outcome but patients with primary disgust emotions had worse treatment effects. The moderator analysis also indicated that scoring high on the obsessing subscale on the Obsessive–Compulsive Inventory-Revised predicted worse treatment outcome in the booster group. In conclusion, there are some possible predictors and moderators of ICBT for OCD but more research is needed with larger and clinically representative samples. [ABSTRACT FROM AUTHOR]

Abstract: Internet-based cognitive behavior therapy (CBT) for severe health anxiety can be effective, but not all patients achieve full remission. Under these circumstances, knowledge about predictors is essential for the clinician in order to make reliable treatment recommendations. The primary aim of this study was to investigate clinical, demographic, and therapy process-related predictors of Internet-based CBT for severe health anxiety. We performed three types of analyses on data from a sample comprising participants (N = 81) who had received Internet-based CBT in a randomized controlled trial. Outcomes were a) end state health anxiety, b) improvement in health anxiety (continuous change scores), and c) clinically significant improvement. Outcomes were assessed at six-month follow-up. The results showed that the most stable predictors of both end state health anxiety and improvement were baseline health anxiety and depressive symptoms. Treatment adherence, i.e. the number of completed treatment modules, also significantly predicted outcome. Notably, health anxiety at baseline was positively associated with symptom improvement while depressive symptoms was negatively related to improvement. Demographic factors were largely without significant impact on end state symptoms or improvement. We conclude that baseline symptom burden and adherence to treatment have strong predictive effects in Internet-based CBT for severe health anxiety. [Copyright &y& Elsevier]

Hypochondriasis is highly prevalent in medical settings, has detrimental effects for affected individuals, and is associated with high societal costs. Although cognitive behavior therapy (CBT) has been shown to be effective in the treatment of hypochondriasis, it is not widely available because of a lack of properly trained therapists. Therefore, it is essential to evaluate therapy forms that require less therapist time. The authors investigated the effect and economic impact of group CBT delivered in a psychiatric setting among 24 people with hypochondriasis. A within-group design with prolonged baseline was used, and all participants received 10 weeks of group-based treatment. The primary outcome measures were the Health Anxiety Inventory and the Illness Attitude Scales. Results indicate significant improvement on both measures at posttreatment and 6-month follow-up (Cohen's d = 1.03-1.72). Medical and nonmedical costs were substantially lowered. The authors conclude that group-based CBT delivered in a psychiatric setting is an effective and potentially highly cost-effective treatment for hypochondriasis. [ABSTRACT FROM AUTHOR]

Background: Internet-based cognitive behavior therapy (CBT) has been shown to be a promising method to disseminate cognitive behavior therapy for social anxiety disorder (SAD). Several trials have demonstrated that Internet-based CBT can be effective for SAD in the shorter term. However, the long-term effects of Internet-based CBT for SAD are less well known.Objective: Our objective was to investigate the effect of Internet-based CBT for SAD 5 years after completed treatment.Method: We conducted a 5-year follow-up study of 80 persons with SAD who had undergone Internet-based CBT. The assessment comprised a diagnostic interview and self-report questionnaires. The main outcome measure was the Liebowitz Social Anxiety Scale-Self-Report (LSAS-SR). Additional measures of social anxiety were the Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS). Attrition rates were low: 89% (71/80) of the participants completed the diagnostic interview and 80% (64/80) responded to the questionnaires.Results: Mixed-effect models analysis showed a significant effect of time on the three social anxiety measures, LSAS-SR, SIAS, and SPS (F(3,98-102) = 16.05 - 29.20, P < .001) indicating improvement. From baseline to 5-year follow-up, participants' mean scores on the LSAS-SR were reduced from 71.3 (95% confidence interval [CI] 66.1-76.5) to 40.3 (95% CI 35.2 - 45.3). The effect sizes of the LSAS-SR were large (Cohen's d range 1.30 - 1.40, 95% CI 0.77 - 1.90). Improvements gained at the 1-year follow-up were sustained 5 years after completed treatment.Conclusions: Internet-based CBT for SAD is a treatment that can result in large and enduring effects.Trial Registration: Clinicaltrials.gov NCT01145690; http://clinicaltrials.gov/ct2/show/NCT01145690 (Archived by WebCite at http://www.webcitation.org/5ygRxDLfK).

Abstract: Social anxiety disorder (SAD) is highly prevalent and associated with a substantial societal economic burden, primarily due to high costs of productivity loss. Cognitive behavior group therapy (CBGT) is an effective treatment for SAD and the most established in clinical practice. Internet-based cognitive behavior therapy (ICBT) has demonstrated efficacy in several trials in recent years. No study has however investigated the cost-effectiveness of ICBT compared to CBGT from a societal perspective, i.e. an analysis where both direct and indirect costs are included. The aim of the present study was to investigate the cost-effectiveness of ICBT compared to CBGT from a societal perspective using a prospective design. We conducted a randomized controlled trial where participants with SAD were randomized to ICBT (n =64) or CBGT (n =62). Economic data were assessed at pre-treatment, immediately following treatment and six months after treatment. Results showed that the gross total costs were significantly reduced at six-month follow-up, compared to pre-treatment in both treatment conditions. As both treatments were equivalent in reducing social anxiety and gross total costs, ICBT was more cost-effective due to lower intervention costs. We conclude that ICBT can be more cost-effective than CBGT in the treatment of SAD and that both treatments reduce societal costs for SAD. [Copyright &y& Elsevier]
