Overview
What is it?
Cognitive Behavioural Therapy (CBT) is a widely practiced form of psychotherapy that helps individuals manage their problems by changing the way they think and behave. It is not naturally occurring but is a structured, goal-oriented therapy that combines cognitive therapy (focusing on thoughts) and behavior therapy (focusing on actions). CBT is used to treat a variety of mental health conditions, including depression, anxiety, and insomnia, and is often recommended as a first-line treatment before medication .
How does it work?
CBT works by identifying and challenging negative thought patterns and behaviors that contribute to depression. It helps individuals replace these with more positive and realistic thoughts, which can improve mood and reduce depressive symptoms. Techniques such as cognitive restructuring (challenging negative beliefs), behavioral activation (engaging in positive activities), and problem-solving are commonly used. For example, cognitive restructuring involves identifying an activating event, the beliefs tied to it, and the consequences, then disputing those beliefs to create a more effective approach .
What are the benefits?
CBT has been shown to be effective in reducing symptoms of depression and preventing relapse. It is particularly beneficial for individuals with mild to moderate depression and can be as effective as antidepressant medication for some people. CBT also helps improve sleep quality, which is often disrupted in depression, and can be adapted for use in children, adolescents, and older adults .
Effectiveness
What does the research say?
Research consistently supports the efficacy of CBT for managing depression. Large effect sizes have been found for CBT in treating unipolar depression, and it is often comparable to or even more effective than medication in some cases. CBT is also effective in reducing relapse rates and improving psychosocial functioning, particularly in individuals with bipolar disorder. Studies have shown that CBT can be adapted for various age groups and comorbid conditions, making it a versatile treatment option .
Side Effects
Emotional discomfort
Emotional discomfort may occur as individuals confront and challenge negative thoughts and behaviors, which can be emotionally taxing .
Temporary increase in anxiety
A temporary increase in anxiety might happen when individuals start to address deeply rooted fears or anxieties during therapy .
Fatigue
Fatigue can result from the intense mental effort required to engage in cognitive restructuring and behavioral changes .
Frustration
Frustration may arise if progress feels slow or if individuals struggle to implement new coping strategies effectively .
