The Bergen 4-day treatment (B4DT) for obsessive-compulsive disorder (OCD) is a concentrated form of exposure and response prevention that has been evaluated and implemented nationwide in Norway. Its effectiveness has yet to be fully established in other countries. A total of 86 patients with OCD underwent the treatment at the Icelandic Anxiety Centre (KMS) from 2018 to 2023. Of these, 61.6% were classified as having severe symptoms, and 38.4% with moderate symptoms. Of the sample, 72.1% had previously received psychological treatment for OCD and 86.0% had at least one comorbid disorder, depression being the most common (50.0%). Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was administered pre-treatment, posttreatment, and at 3-month follow-up, along with measures on general anxiety, depression, and occupational impairment. The mean score on Y-BOCS was 30.5 (SD = 3.6) pre-treatment, 10.6 (SD = 4.1) posttreatment and 10.9 (SD = 5.4) at 3-month follow-up. By the end of treatment, 94.9% of the patients had responded and 68.0% were in remission. At the 3-month follow-up, 92.5% were responders and 67.9% remitters. Participants were satisfied with the treatment and had improved in terms of occupational functioning, which was maintained at follow-up. These preliminary results suggest that the B4DT may be a swift and effective treatment format for OCD.

Exposure therapy is an efficacious treatment for anxiety-related disorders. Yet, fear often returns after treatment. Occasional reinforcement, in which the feared stimulus is intermittently presented during extinction, increases safety learning and slows fear renewal in conditioning paradigms and analogue samples, but no studies to date have examined this strategy in clinical samples. The present study examined the effects of vicarious occasional reinforcement on fear renewal in a snake-phobic sample across multiple levels of analysis. Fear was intermittently reinforced by providing reminders of the feared outcome (a snake bite) throughout a two-session analogue video exposure manipulation. Snake-phobic adults were randomized to one of three conditions: a single-cue [S], multiple-cue [M], or multiple-cue+fear-outcome [M+FO] exposure group. Results showed the three groups did not significantly differ in threat expectancy or attentional bias for threat at follow-up. Despite sustained anxiety, however, the M+FO condition completed significantly more steps on a visual avoidance task at follow-up than the M and S conditions and heightened mean distress during exposure mediated this effect. The M and S groups did not significantly differ in visual avoidance at follow-up. These findings suggest incorporating reminders of the feared outcome into exposure may be an effective strategy for increasing inhibitory retrieval.

The goal of this study was to understand how mindful awareness, acceptance, and values-consistent action change across acceptance-based behavioral therapy (ABBT) for generalized anxiety disorder (GAD) and determine their effect on symptoms. We examined weekly data from 31 individuals who received ABBT as part of a randomized control trial for individuals with GAD (Hayes-Skelton, Roemer, & Orsillo, 2013). Participants answered questions weekly about three components of ABBT, including the percentages of time they spent over their past week: 1) aware of the present moment, 2) accepting of their internal experiences, and 3) engaging in values. GAD symptoms were examined using two self-report measures (DASS-21 Stress subscale and PSWQ) and two clinician-rated interview measures (CSR and SIGH-A) at pre- and post-treatment.¹ Mindful awareness, acceptance, and values-consistent action increased linearly across ABBT. All three change trajectories were positively correlated (Z's 2.99 to 8.74, p's < .001). Mindful awareness, acceptance, and values-consistent action across treatment predicted decreases in GAD symptoms above and beyond baseline for most outcome measures (Z's -1.95 to -3.03, p's < .05), with the exception that mindfulness did not predict DASS-stress (Z = -1.39, p = .17). These findings are consistent with the structure and model of ABBT.

Interoceptive exposure (IE) exercises are underused, especially in people with chronic physical health problems. Secondary data analyses were conducted to examine the use of and acute responses to IE exercises in individuals with and without a history of chronic physical health problem(s). Participants (N = 413; Mage = 38.6, 56.1% with chronic physical health problems) enrolled in a 6-month randomized controlled trial that aimed to reduce anxiety and depression. Participants had access to a smartphone-based intervention that included on-demand access to IE exercises: head rush, straw breathing, chair spinning, fast breathing, and running in place. Utilization of the IE exercises and acute responses to the exercises were evaluated in the context of chronic physical health problem history. Participants with versus without a chronic physical health problem completed statistically significantly more IE exercises. Acute effects of IE exercises on distress and physical sensations were similar for those with and without a history of chronic physical health problems, as well as those who were versus were not taking medication. There is no evidence that chronic disease history influences the acute response to IE exercises. Continued research is needed to further assess the safety of IE exercises in people with various medical conditions.

Exercise directly improves mood and cognition. Providing exercise immediately before cognitive behavior therapy (CBT) sessions may therefore enhance the clinical responsiveness to CBT. The present pilot study examined the feasibility and direction of effect of exercise+CBT versus CBT in depressed outpatients using a stepped wedged design. Thirty-three patients received either group-based CBT (12-16 weeks) or group-based exercise+CBT within specialized mental healthcare settings. Weekly therapist-supervised exercise sessions (45 min, moderate intensity, running/indoor cycling) were provided directly before the CBT sessions, with encouragement for home-exercise. Feasibility was assessed through recruitment, retention, and safety, alongside treatment adherence and treatment effects on clinically relevant outcomes. Recruitment yielded 37% of eligible patients with similar retention rates across conditions. No adverse events were reported. The exercise+CBT condition attended 63% of supervised exercise sessions (72% at moderate/vigorous intensity) and fewer CBT sessions (42%) compared to the CBT condition (54%). The conditions showed similar improvements in depressive symptoms, rumination, and CBT skills over time. Our study shows in a specialized mental health care routine practice population that providing exercise before CBT sessions is feasible, warranting a future randomized controlled trial.

Despite efforts to implement evidence-based guidelines, little is known about the quality of cognitive-behavioural therapy (CBT) for depression, anxiety disorders, obsessive-compulsive disorder, and posttraumatic stress disorder in routine clinical practice. The present study aimed to investigate therapist adherence to CBT, and related aspects of quality of care, from a patient perspective. In a cross-sectional study, 90 participants from 21 routine psychiatric outpatient units in Stockholm completed a web-based survey post-CBT. Participants reported a high degree of therapist adherence to CBT techniques and procedures (M = 3.02 on a scale of 0 to 4), with higher adherence for social anxiety disorder and posttraumatic stress disorder than for depression (p = .002, ω² = 0.21). Therapist adherence was moderately correlated with patient improvement (τs = .37-.38, ps < .001). Participants reported a high degree of symptom improvement (M  = 3.10) and treatment satisfaction (M = 3.38) and received a median of 15 sessions. Also, we found examples of excessive healthcare provision and non-adherence, as 17% far exceeded the recommended number of sessions, 80% had concurrent psychotropic treatments despite lower guideline priority, and 11% took benzodiazepines though not recommended. In conclusion, we found that CBT was delivered with high quality.
