Summary
Internet-delivered acceptance-based behavior therapy shows promise for generalized anxiety disorder (GAD). This new online treatment effectively reduced worry and maintained results in a pilot study.
Area of Science:
- Clinical Psychology
- Digital Therapeutics
- Anxiety Disorders
Background:
- Generalized anxiety disorder (GAD) is a prevalent condition often treated with cognitive behavior therapy (CBT).
- Internet-delivered CBT (ICBT) offers a scalable approach to mental healthcare.
- Acceptance-based behavior therapy (ABT) integrates mindfulness and acceptance strategies, but its internet delivery for GAD is novel.
Purpose of the Study:
- To describe the functionality of a new internet-delivered ABT program for GAD.
- To evaluate the preliminary efficacy of this novel ICBT intervention in an open pilot trial.
Main Methods:
- Fourteen patients diagnosed with GAD from primary care clinics were enrolled.
- The internet-delivered ABT program involved acceptance techniques, behavioral components, and homework over approximately 15 weeks.
- Outcome measures were assessed at post-treatment and 2-3 months follow-up; 10 patients completed follow-up assessments.
Main Results:
- A high completion rate for treatment modules was observed.
- Significant within-group improvement in worry symptoms (Cohen's d = 2.14) was found at post-treatment.
- Treatment gains were maintained at follow-up, with high client satisfaction ratings.
Conclusions:
- Internet-delivered acceptance-based behavior therapy appears to be a promising intervention for GAD.
- The positive outcomes in this pilot trial support further investigation.
- A controlled trial evaluating this ICBT program for GAD has been completed.

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

538
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:24Rational Emotive Behavior Therapy

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

01:22Generalized Hooke's Law
2.7K
The generalized Hooke's Law is a broadened version of Hooke's Law, which extends to all types of stress and in every direction. Consider an isotropic material shaped into a cube subjected to multiaxial loading. In this scenario, normal stresses are exerted along the three coordinate axes. As a result of these stresses, the cubic shape deforms into a rectangular parallelepiped. Despite this deformation, the new shape maintains equal sides, and there is a normal strain in the direction of the...
