Article
Procrastination can be a persistent behavior pattern associated with personal distress. However, research investigating different treatment interventions is scarce, and no randomized controlled trial has examined the efficacy of cognitive-behavior therapy (CBT). Meanwhile, Internet-based CBT has been found promising for several conditions, but has...

Major depression occurs in 5–10% of pregnancies and is associated with many negative effects for mother and child, yet treatment options are scarce. To our knowledge, this is the first published randomised controlled trial on Internet delivered Cognitive Behavior Therapy (ICBT) for this group. Objective To test the efficacy of a pregnancy adapted...
Article

Objective: To minimize the burden in detecting and monitoring Panic Disorder and Agoraphobia by developing a very brief scale with selected items from the Panic Disorder Severity Scale-Self Report (PDSS-SR), and to investigate the proposed scale's psychometric properties in a comorbid sample. Methods: A sample of 5103 patients from the Internet...
Article
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' w...
Article
Full-text available
Background: There is often a waiting period for people who seek psychiatric treatment for depression or anxiety. As this delay risks worsening symptoms, an alternative could be to provide an intervention that requires minimal resources during the waiting period. Aims: The aim was to investigate if a digital problem-solving intervention delivered...
Article
Full-text available
Insomnia is a common and chronic disorder, and cognitive behavioral therapy (CBT) is the recommended treatment. Very long-term follow-ups of CBT are very rare, and this study aimed to investigate if improvements were stable one and ten years after CBT for insomnia (CBT-i). Based on a three-armed randomized controlled trial of bibliotherapeutic CBT-...

Insomnia disorder is highly prevalent, and has been identified as a risk factor for many psychiatric problems, including depression, suicide ideation and suicide death. Previous studies have found that cognitive behavioral therapy for insomnia (CBT-I) reduce depression and suicidal ideation in samples with high levels of suicidal ideation. This stu...
Article
Background Internet cognitive behavioural therapy (iCBT) is a viable delivery format of CBT for depression. However, iCBT programmes include training in a wide array of cognitive and behavioural skills via different delivery methods, and it remains unclear which of these components are more efficacious and for whom. Methods We did a systematic revi...
Article

The objectives were to investigate the potential for sleep‐related behaviours, acceptance and cognitions to predict outcome (insomnia severity) of cognitive behavioural therapy for insomnia (CBT‐I). Baseline and outcome data from four randomised controlled trials (n = 276) were used. Predictors were the Dysfunctional Beliefs and Attitudes about Sle...
Article
Introduction: Adaptive Treatment Strategies warns therapists of patients at risk of treatment failure to prompt an adaption of the intervention. Internet-delivered Cognitive Behavioural Therapy (ICBT) collects a wide range of data before and during treatment and can quickly be adapted by adjusting the level of therapist support. Objectives: To eval...

Objective To develop a very brief scale with selected items from the Insomnia Severity Index (ISI), and to investigate the psychometric properties of the proposed scale in a psychiatric sample. Methods Patient data from seven Cognitive Behavioral Therapy (CBT) for insomnia trials and from regular care were used in psychometric analyses (N = 280-15...

Importance Personalized treatment choices would increase the effectiveness of internet-based cognitive behavioral therapy (iCBT) for depression to the extent that patients differ in interventions that better suit them. Objective To provide personalized estimates of short-term and long-term relative efficacy of guided and unguided iCBT for depressi...

A learning machine, in the form of a gating network that governs a finite number of different machine learning methods, is described at the conceptual level with examples of concrete prediction subtasks. A historical data set with data from over 5000 patients in Internet-based psychological treatment will be used to equip healthcare staff with deci...
Article
Background Major Depressive Disorder (MDD) is a serious, but treatable, disorder where Cognitive Behavioral Therapy (CBT) is a first line treatment. However, a significant number of patients (40–60%) are not responding to treatment and understanding more about the disorder and who responds to treatment is crucial to improve outcomes. In the past ye...

Disorder-specific internet-based cognitive–behavioural therapy (ICBT) is effective for depression, panic disorder and social anxiety. In this benchmarking study, a new, individually tailored, ICBT programme (TAIL) showed effects on depression ( n = 284, d = 1.33) that were non-inferior to disorder-specific ICBT for depression in routine care ( n =...
Article
Procrastination is a common self-regulatory failure that can have a negative impact on well-being and performance. However, few clinical trials have been conducted, and no follow-up has ever been performed. The current study therefore aimed to provide evidence for the long-term benefits and investigate predictors of a positive treatment outcome amo...

Project
Attempt to create algorithms and tools for predicting outcomes of individual patients who are already in treatment, and then use adaptive treatment strategies to try and avoid failed treatment attempts. This will make the treatments more effective over all (fewer patients with poor outcomes) while still maintaining the stepped care principle of starting with the same, low-intensity treatment, for all patients.
Archived project
1) Investigate the efficacy of cognitive behavior therapy for procrastination using an Internet-based treatment with or without guidance from a therapist. 2) Investigate the long-term outcomes of treatment. 3) Evaluate the psychometric properties of the Swedish version of the Pure Procrastination Scale, the Irrational Procrastination Scale, and the Susceptibility to Temptation Scale. 4) Explore possible subgroups of procrastinators.
