Effectiveness of psychological and educational interventions for the prevention of depression in the workplace: A systematic review and meta-analysis.

Objectives Psychological and educational interventions for the prevention of depression have a small-to-moderate effect. However, little is known about their effectiveness in the workplace. We aimed to evaluate the effectiveness of such interventions through a systematic review and meta-analysis of randomized controlled trials (RCT). Methods We searched PubMed, PsycINFO, EMBASE, CENTRAL, CIS-DOC and Open Grey for RCT. Search was supplemented with manual searches of reference lists of relevant meta-analyses and trials. We included RCT that assessed either the incidence of depression or the reduction of depressive symptoms, which excluded participants with baseline depression. Measurements were required to have been made using validated instruments and participants recruited in the workplace. Independent evaluators selected studies, evaluated risk bias (Cochrane Collaboration's tool) and extracted from RCT. The combined OR was estimated using the fixed-effects model. Heterogeneity was measured by I 2and Cochrane's Q. Results Of the 1963 abstracts reviewed, 69 were selected for review in fulltext. Only three RCT met our inclusion criteria, representing 1246 workers from three different countries and continents. The combined odds ratio was 0.25 [95% confidence interval (CI) 0.11-0.60, P=0.002]; I 2=0% and Q=0.389 (P=0.823). The risk of bias was low in one RCT and moderate and high in the other two, respectively. Conclusion Psychological or educational interventions in the workplace may prevent depression, although the quality of evidence was low.

Fundamentos teóricos a problemas clínicos en los trastornos de la personalidad y su proyección en el DSM-5/CIE-11 / Theoretical background in personality disorders: clinical problems and their projection in DSM-5/ICD-11

More research needs to be carried out into the theoretical backgrounds of the various specialities in Medicine, and particularly in Psychiatry. Since new classifications for mental disorders are soon to be introduced, we will briefly examine the history of personality disorders and our interest will be directed to problems we might encounter using the current diagnostic criteria, i. e., DSM-IV/ICD-10.

Profundizar en los fundamentos teóricos de la propia especialidad es algo necesario para la labor asistencial de cualquier facultativo en Medicina. Ante las ya inminentes nuevas clasificaciones sobre las enfermedades mentales, hacemos un breve repaso de la historia de los trastornos de personalidad y nos planteamos las principales dificultades que se ponen de manifiesto al hacer el diagnóstico de trastorno de personalidad siguiendo los actuales criterios DSM-IV/CIE-10.
