Battling in the trenches: case managers' ability to combat the effects of mental illness stigma on consumers' perceived quality of life.

Intervention effectiveness research requires that investigators include "real world" variables in the design of studies to develop an understanding of how interventions perform in the "real world." Two areas that have been neglected in effectiveness research on mental health case management are mental illness self-stigma and the effects of different case managers. Self-stigma is a reality for many consumers that negatively impacts their lives. Case managers, themselves, are a potential source of autocorrelation and likely provide services differently. This study explores the relationship between self-stigma and quality of life for consumers receiving services from different case managers. Cross-sectional data were collected from 160 consumers of an urban case management agency. Self-stigma was negatively associated with quality of life. Case managers did not account for a significant amount of variance in quality of life scores. However, the interaction between case manager and self-stigma was significant. Some case managers were able to mitigate the negative effects of self-stigma on quality of life. Future effectiveness research in community mental health case management needs to account for the effects of self-stigma, case managers, and the interaction between the two in the research design.
