You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Outcome", "Participant", "Intervention"].

Please return the output as a JSON object of the format: {"Participant" : ["patients with COPD", ...], "Intervention" : ["Atenolol", ...], "Outcome" : ["blood pressure", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Abstract:

Family economic empowerment and mental health among AIDS-affected children living in AIDS-impacted communities : evidence from a randomised evaluation in southwestern Uganda . OBJECTIVE The authors examine whether an innovative family economic empowerment intervention addresses mental health functioning of AIDS-affected children in communities heavily impacted by HIV/AIDS in Uganda . METHODS A cluster randomised controlled trial consisting of two study arms , a treatment condition ( n=179 ) and a control condition ( n=118 ) , was used to examine the impact of the family economic empowerment intervention on children 's levels of hopelessness and depression . The intervention comprised matched children savings accounts , financial management workshops and mentorship . Data were collected at baseline and 12 months post-intervention . RESULTS Using multivariate analysis with several socioeconomic controls , the authors find that children in the treatment condition ( receiving the intervention ) report significant improvement in their mental health functioning . Specifically , the intervention reduces hopelessness and depression levels . On the other hand , children in the control condition ( not receiving the intervention ) report no changes on both measures . CONCLUSIONS The findings indicate that children with poor mental health functioning living in communities affected by HIV/AIDS may benefit from innovative family economic empowerment interventions . As measures of mental health functioning , both hopelessness and depression have long-term negative psychosocial and developmental impacts on children . These findings have implications for public health programmes intended for long-term care and support of children living in resource poor AIDS-impacted communities .
