Effectiveness of augmented Individual Placement and Support interventions for competitive employment in people with schizophrenia: Systematic review and meta-analysis
##plugins.themes.bootstrap3.article.main##
Resumen
Antecedentes. Se ha estimado que más del 70% de las personas que viven con diagnóstico de esquizofrenia desean trabajar. El modelo Individual Placement and Support (IPS) ha mostrado efectividad para que las personas con esquizofrenia consigan un empleo competitivo. Sin embargo, en esta población no se ha evaluado la eficacia de las intervenciones aumentadas de IPS –es decir, aquellas que añaden al modelo una intervención psicosocial–.
Objetivo. Evaluar la eficacia de las intervenciones aumentadas de IPS dirigidas a la obtención de empleo competitivo en personas con esquizofrenia.
Método. Se realizó una revisión sistemática de la literatura de ensayos clínicos aleatorizados sobre intervenciones aumentadas de IPS publicados en inglés entre 2007 y 2017, en las bases de datos electrónicas de PubMed, Science Direct y EBSCO. Se calcularon el riesgo de sesgo y las tasas de empleo competitivo. Se realizó un metaanálisis mediante el método de efectos aleatorios para estimar el efecto de las intervenciones aumentadas de IPS.
Resultados. Se identificaron 12 artículos en los que se comparaban 10 intervenciones aumentadas de IPS con alguna otra intervención. En ocho estudios realizados en personas con esquizofrenia, la intervención se basó en IPS + habilidades sociales/habilidades laborales/remediación cognitiva vs. IPS o IPS modificadas, sin que se encontrara un efecto general en favor de las intervenciones aumentadas (RR = 1.37, 95% IC [.97, 1.95], I2 = 52%). Las intervenciones aumentadas de IPS tienden a ser más efectivas cuando se llevan a cabo en el primer episodio psicótico.
Discusión y conclusión. No se puede concluir que las intervenciones aumentadas de IPS tengan un mayor efecto sobre las intervenciones estándar de IPS para la obtención de empleo competitivo en personas con esquizofrenia.
