Previous chapters focused on the qualitative phase of this mixed-methods study exploring the well-being outcomes of officer–recipient relationships. This chapter, instead, focuses on the quantitative phase that consisted in the application of surveys to 312 recipients of Oportunidades-Prospera. Three scales were used to assess well-being and officer–recipient relationships. First, the global questions of happiness and life satisfaction; second, the multidimensional and psychosocial model of inner well-being (IWB); and third, the quality of officer–recipient relationships (QoR) scale constructed based on the interviews and focus groups with recipients on what constituted a positive and a negative relationship. This chapter explains the construction of the IWB and QoR scales through factor analytic procedures, and then uses the resulting indicators to evaluate the statistical association between well-being and this relationship through variance, correlation, and regression analyzes. The statistical analyzes largely corroborate the qualitative findings and further indicate the need to assess the effects of positive and negative interactions separately. The results show that on average recipients in Cualcan experienced significantly better relationships compared to those in Nexpan. Additionally, recipients with a role in the program (vocal or committee member) experienced worse relationships than the average recipient. Finally, interactions with officers had a significant effect over the subjective and psychosocial well-being of recipients. For recipients overall, positive interactions improved happiness and the domains of values and meanings, social connections, and economic confidence. Yet, especially for vocales and committee members, having positive and negative interactions were more important for their sense of political participation, social recognition, and life satisfaction, but less so for their economic confidence primarily.
