Summary
Massed group cognitive behavioural therapy (CBT) delivered over 3 weeks is as effective as traditional spaced CBT for panic disorder. This intensive approach shows comparable outcomes and feasibility for patients.
Area of Science:
- Psychiatry
- Clinical Psychology
- Behavioral Therapy
Background:
- Panic disorder (PD) with or without agoraphobia is a significant mental health concern.
- Standard treatment often involves spaced weekly group cognitive behavioural therapy (CBT).
- Alternative delivery models for CBT, such as massed formats, warrant investigation for efficacy and feasibility.
Purpose of the Study:
- To compare the effectiveness of massed versus spaced group cognitive behavioural therapy (CBT) for patients diagnosed with panic disorder (PD).
- To evaluate treatment outcomes and patient adherence in both massed and spaced CBT groups.
Main Methods:
- Thirty-nine PD patients were randomized into two groups: massed group CBT (intensive sessions over 3 weeks) or traditional spaced weekly group CBT (13 sessions).
- Both treatment protocols involved identical content and total hours.
- Outcomes were assessed post-treatment and at 3, 6, and 18-month follow-ups.
Main Results:
- Both massed and spaced CBT groups demonstrated significant improvements across all outcome measures.
- Large effect sizes were observed from pre-treatment to post-treatment and follow-up.
- No statistically significant differences were found between the massed and spaced CBT groups regarding efficacy, adherence, or patient satisfaction.
Conclusions:
- A massed, 3-week group CBT schedule is an effective and feasible treatment option for patients with panic disorder.
- The outcomes of the massed CBT approach are comparable to those of the standard, spaced group CBT.
- This suggests that intensive CBT delivery can be a viable alternative for PD treatment.

01:27Panic Disorder
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
01:22Behavior 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.

01:25Cognitive 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...
01:30Generalized Anxiety Disorder
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...
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 Ellis's...
