Summary
Acceptance and commitment therapy (ACT) shows promise in reducing suicidal ideation. However, the current evidence is limited by a high risk of bias in included studies, necessitating further research.
Area of Science:
- Psychiatry
- Psychology
- Clinical Psychology
Background:
- Acceptance and commitment therapy (ACT) is an established treatment for various mental health conditions.
- Existing meta-analyses confirm ACT's efficacy in depression, anxiety, and pain, but its impact on suicidality remains unclear.
Purpose of the Study:
- To systematically review and meta-analyze the therapeutic effectiveness of ACT specifically for suicidality.
- To evaluate ACT's impact on suicidal ideations and attempts.
Main Methods:
- A systematic search of major electronic databases (PubMed, Embase, Scopus, Cochrane Library) was conducted.
- The primary outcome was the effectiveness of ACT in reducing suicidal ideations and attempts.
Main Results:
- Eight studies were included in the meta-analysis, all exhibiting a high risk of bias.
- A pooled standardized mean difference of 1.122 (95% CI = 0.261 to 1.982) indicated ACT's effectiveness for suicidal ideations.
Conclusions:
- This meta-analysis suggests ACT may be effective in reducing suicidal ideation.
- A significant limitation is the high risk of bias across the included studies.
- Further high-quality, well-designed research is required to validate these preliminary findings.

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...

Research has highlighted several critical factors that influence the effectiveness of psychotherapy, such as the therapeutic alliance, the therapist, and the client.
The Therapeutic Alliance
The therapeutic alliance refers to the relationship between the therapist and the client. The alliance strengthens when the therapist and the client engage in a nurturing, supportive, trusting, empathetic, and respectful relationship, improving therapeutic outcomes.

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

27
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...

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Interpersonal psychotherapy (IPT) is a structured, time-limited therapeutic approach initially developed to treat depression. It integrates key concepts from psychodynamic, humanistic, and cognitive-behavioral therapies, making it a uniquely eclectic framework. The therapy is rooted in the interpersonal theories of Adolph Meyer and Harry Stack Sullivan, as well as John Bowlby's attachment theory, and focuses on the interplay between interpersonal relationships and emotional well-being.
