This study aimed to find out what effects the United Nations High Commissioner for Refugees (UNHCR) and United Nations Children’s Fund (UNICEF) cash assistance has had on beneficiaries’ lives. It had the following objectives: (1) to evaluate beneficiary spending patterns and their effect on family well-being; (2) to evaluate the efficiency, effectiveness and accountability of cash assistance provided by UNHCR and the Child Cash Grant (CCG) provided by the UNICEF; and (3) to evaluate the complementarity of (as well as gaps in) programming by UNICEF, UNHCR and the World Food Programme (WFP) in targeting the most vulnerable groups. The study used mixed-methods included a literature review as well as one round of quantitative data collection and two rounds of qualitative data collection. The quantitative findings were collected through household surveys completed by respondents in 2,114 randomly selected households spread across four governorates (Amman, Irbid, Mafraq and Zarqa) between December 2016 and March 2017. In order to explore the effects of different types of cash assistance, as well as to ascertain how they complement one another, respondent households were selected from six groups of social assistance beneficiaries.
