Effectiveness of psychotherapy: Synthesis of a "meta-analytic research domain" across world regions and 12 mental health problems.

The scientific output generated in psychology has surged in recent decades, including the number of studies investigating psychological treatments. To keep track of all this evidence, we developed the "Metapsy" meta-analytic research domain: a comprehensive system of open databases and tailored software that allows for rapid evidence generation. We leverage this novel infrastructure to summarize the effect of psychological treatment across 12 mental health problems and trace back the global expansion of psychotherapy research over the past 50 years.

Access to treatment protocols and manuals for evidence-based psychological interventions for severe mental disorders: a survey of randomised trials included in network meta-analyses.

Background: Evidence-based psychological interventions for mental disorders are described in treatment protocols and manuals, which detail treatment components and conditions of application. Systematic evaluations of the accessibility of treatment protocols and manuals across multiple mental disorders are absent.

Objective: We assessed whether treatment protocols or manuals for psychological interventions for severe mental disorders are accessible and publicly available.

Reevaluating the brain disease model of addiction.

The brain disease model of addiction has dominated public and scientific discourse on addiction (termed substance use disorder [SUD] in the DSM-5) over the past 3 decades. The model framed addiction as a chronic and relapsing brain disease caused by structural and functional brain alterations. The purpose of this model was purportedly dual, as both an aetiological theory and a tool to reduce stigma.

Self-reports vs clinician ratings of efficacies of psychotherapies for depression: a meta-analysis of randomized trials.

Aims: The comparability between self-reports and clinician-rated scales for measuring depression following treatment has been a long-standing debate, with studies finding mixed results. While the use of self-reports in psychotherapy trials is very common, it has been widely assumed that these tools pose a validity threat when masking of participants is not possible. We conducted a meta-analysis across randomized controlled trials (RCTs) of psychotherapy for depression to examine if treatment effect estimates obtained via self-reports differ from clinician-rated outcomes.

A meta-analysis of the association of death anxiety with psychological distress and psychopathology.

Death anxiety (DA), apprehension when thinking about death, has long been associated with distress. Studies have suggested that DA may transdiagnostically contribute to mental disorders. We conducted a systematic review and meta-analysis, aiming to estimate the relationship between DA and distress or symptoms of mental disorders.

Communicating scientific evidence: drugs for Alzheimer's disease as a case study.

This paper reviews the scientific evidence on new anti-amyloid monoclonal antibodies for treating Alzheimer's disease as a case study for improving scientific evidence communication. We introduce five guidelines condensed from the biomedical evidence literature but adapted to the short format of science communication in e.g.

Absolute and relative outcomes of psychotherapies for eight mental disorders: a systematic review and meta-analysis.

Psychotherapies are first-line treatments for most mental disorders, but their absolute outcomes (i.e., response and remission rates) are not well studied, despite the relevance of such information for health care users, providers and policy makers.
