Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
Operant Conditioning Intervention01:24

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...
Cognitive Therapy01:25

Cognitive Therapy

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...
Rational Emotive Behavior Therapy01:24

Rational 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 Ellis's...
Behavior Therapy01:22

Behavior Therapy

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.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...
Beck's Cognitive Therapy01:25

Beck's Cognitive Therapy

Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.

Area of Science:

  • Psychiatry
  • Mental Health
  • Digital Therapeutics

Background:

  • Cognitive Behavior Therapy (CBT) is effective for Obsessive Compulsive Disorder (OCD).
  • Limited access to trained CBT therapists presents a barrier to treatment.
  • Internet-based CBT (ICBT) offers a scalable solution to improve access.

Purpose of the Study:

  • To evaluate the efficacy of a therapist-supported ICBT program for OCD.
  • To assess changes in OCD symptom severity and related psychological outcomes.

Main Methods:

  • An open trial involving 23 patients receiving a 15-week ICBT program.
  • Treatment included psychoeducation, cognitive restructuring, and exposure with response prevention.
  • Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure, assessed pre- and post-treatment.

Main Results:

  • Significant reductions in OCD symptoms were observed (Cohen's d = 1.56).
  • Post-treatment, 61% of participants showed clinically significant improvement; 43% no longer met OCD diagnostic criteria.
  • Statistically significant improvements were noted in self-rated OCD symptoms, general functioning, and depression.

Conclusions:

  • Therapist-supported ICBT effectively reduces OCD and depressive symptoms.
  • ICBT improves general functioning in individuals with OCD.
  • Further randomized controlled trials are necessary to confirm these findings.
