Often community intervention researchers focus primarily on identifying generaliz able program outcomes, assuming equal effectiveness for all participants. This narrow focus neglects program participants’ diverse needs and outcomes. This presentation will focus on the diverse experiences of participants in a Housing First program on O‘ahu. The Housing First model eliminates traditional housing prerequisites (e.g., sobriety, psychiatric treatment), with the aim of moving program participants into permanent, supportive housing as quickly as possible (Tsemberis, Gulcur, & Nakae, 2004). The Housing First model has a strong evidence base and is deemed an effective approach to addressing homelessness, even in the presence of mental illness and substance abuse (Padgett, Gulcur, & Tsemberis, 2006). Despite widespread adoption of the model and considerable research on program outcomes, minimal research has examined within- setting differences experienced by Housing First participants. The current study tested a series of latent class growth models to identify unique trends over a four- year period. Monthly- reported quality of life data, participant histories, community engagement, and service delivery were used to identify the participants who followed unique trajectories over the course of the program. These findings have aided our work by identifying how services delivery can be amended to meet the specific and diverse needs of program participants and opened to door to pursuing new qualitative investigations. Our presentation will 1) highlight the diversity of participants entering the Housing First program; 2) demonstrate how their unique characteristics may have impacted their success in the program; and 3) recommend program adaptations that address the diverse needs of Housing First participants.
