A qualitative approach to the evaluation of psychosocial interventions for persons with severe mental illness.

This article describes the development and assessment of a qualitative interview for comprehensively assessing both the process and the outcome of interventions for persons with severe mental illness (SMI). A open-ended 16-question Narrative Evaluation of Intervention Interview (NEII) was developed. The NEII contains questions that ask the participants to evaluate and describe both process and outcome of interventions for persons with SMI. Research participants were 64 persons with SMI attending rehabilitation programs in the community. Analysis of participants' responses to the NEII, using the open step of the grounded theory approach, produced a comprehensive set of themes. Interrater reliabilities for these themes ranged from moderate to high, and these themes differentiated between the three psychosocial interventions. Ways of modifying the NEII so as to make it more sensitive to participants' expectations and experiences are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
