Objective: Although evidence supports the effectiveness of psychological interventions for prevention of anxiety, little is known about their cost-effectiveness. The aim of this study was to conduct a systematic review of health-economic evaluations of psychological interventions for anxiety prevention.

Methods: PubMed, PsycInfo, Web of Science, Embase, Cochrane Central Register of Controlled Trials, EconLit, National Health Service (NHS) Economic Evaluations Database, NHS Health Technology Assessment, and OpenGrey databases were searched electronically on December 23, 2022.

There is limited evidence regarding the effectiveness of preventive interventions for anxiety disorders. We aim to test the effectiveness of multiple health behavior change (MHBC) interventions in the reduction of symptoms of anxiety in the adult population. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted by searching the most relevant databases and registry platforms in the area.

The Research Network on Preventive Activities and Health Promotion (redIAPP), a reference network and promoter of primary care research was created in 2003 thanks to the program Thematic Networks for Cooperative Research in Health (RETICS) of the Instituto de Salud Carlos III (ISCIII). Its creation has meant a radical change in the situation of research in primary care. Throughout its 19 years (2003-2021), different research groups and autonomous communities have participated, and different lines of research have been developed with numerous projects and publications.

Depression is strongly associated with obesity among other chronic physical diseases. The latest mega- and meta-analysis of genome-wide association studies have identified multiple risk loci robustly associated with depression. In this study, we aimed to investigate whether a genetic-risk score (GRS) combining multiple depression risk single nucleotide polymorphisms (SNPs) might have utility in the prediction of this disorder in individuals with obesity.

Article Synopsis
  • This study assessed a Multiple Health Behaviour Change (MHBC) intervention aimed at improving smoking cessation, physical activity, and adherence to a Mediterranean diet among individuals aged 45-75, comparing it to standard care in Spanish Primary Health Care centers.
  • The trial involved 3,062 participants in a cluster randomized design, where the intervention focused on individual, group, and community strategies and was evaluated using a mixed-methods approach for implementation outcomes.
  • Results showed that the intervention led to greater positive changes in health behaviors, particularly dietary changes, with moderate acceptability and fidelity among health professionals, alongside high initial acceptability from participants.

Background: The relationship between the quality of the diet and the adherence to the Mediterranean diet with the presence of persistent or recurrent depressive symptoms have been described. The objective of this study is to analyze the relationship between adherence to the Mediterranean diet and the intake of specific foods in primary care patients aged 45 to 75, having subclinical or major depression. The study also specifically analyzes this relationship in individuals suffering from chronic diseases.

Psychological interventions have been proven to be effective to prevent depression, however, little is known on the cost-effectiveness of psychological interventions for the prevention of depression in various populations. A systematic review was conducted using PubMed, PsycINFO, Web of Science, Embase, Cochrane Central Register of Controlled Trials, Econlit, NHS Economic Evaluations Database, NHS Health Technology Assessment and OpenGrey up to January 2021. Only health-economic evaluations based on randomized controlled trials of psychological interventions to prevent depression were included.

Although evidence exists for the efficacy of interventions to prevent depression, little is known about its prevention through online interventions. We aim to assess the effectiveness of online psychological and psychoeducational interventions to prevent depression in heterogeneous populations. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted based on literature searches in eight electronic data bases and other sources from inception to 22 July 2019.

The aim of this study was to assess the available evidence on potential moderators of psychological and psychoeducational interventions for the prevention of anxiety. A systematic review using PubMed, PsycINFO, Web of Science, Embase, OpenGrey, and CENTRAL was performed up to October 2019. Two independent researchers assessed the fulfillment of eligibility criteria, extracted the data and performed a quality assessment of the included studies.

In primary health care only chronic pain surpass depression and anxiety in loss of quality-adjusted life years. More than 70% of people suffering from common mental disorders consulted their GPs for this reason. However, 'the declining halves rule' is a reality: less than 50% of primary care attendees with common mental disorders were correctly diagnosed, of these less than 50% received adequate treatment (pharmacological or psychological) and of these less than 50% patients were adherent.

Although efforts have been undertaken to determine how psychological interventions exert their effects, research on mediators and mechanisms of change remains limited, especially in the field of prevention. We aimed to assess available evidence on mediators of psychological and psychoeducational interventions for the prevention of depression and anxiety in varied populations. A systematic review using PubMed, PsycINFO, Web of Science, Embase, OpenGrey, and the Cochrane Central Register of Controlled Trials was performed.

Background: The predictD intervention, a multicomponent intervention delivered by family physicians (FPs), reduced the incidence of major depression by 21% versus the control group and was cost-effective. A qualitative methodology was proposed to identify the mechanisms of action of these complex interventions.

Purpose: To seek the opinions of these FPs on the potential successful components of the predictD intervention for the primary prevention of depression in primary care and to identify areas for improvement.

Background: Health promotion is a key process of current health systems. Primary Health Care (PHC) is the ideal setting for health promotion but multifaceted barriers make its integration difficult in the usual care. The majority of the adult population engages two or more risk behaviours, that is why a multiple intervention might be more effective and efficient.

Background: Depression is viewed as a major and increasing public health issue, as it causes high distress in the people experiencing it and considerable financial costs to society. Efforts are being made to reduce this burden by preventing depression. A critical component of this strategy is the ability to assess the individual level and profile of risk for the development of major depression.
