OBJECTIVE: This study investigates the association between impulsiveness and six dimensions of recovery among homeless people with mental illness.METHOD: The sample was composed of 418 participants of a randomized controlled trial of Housing First, a recovery-oriented program that provides immediate access to permanent housing. The reliable change index method was used to provide an estimate of the statistical and clinical significance of the change from baseline to 24 months (i.e., clinically meaningful improvement), on outcomes that pertain to recovery dimensions: psychiatric symptoms (clinical), physical health and substance use problems (physical), residential stability (functional), arrests (criminological), community integration (social), and hope and personal confidence (existential). We tested for the effect of impulsiveness, assessed with the Barratt Impulsiveness Scale-11, on clinically meaningful improvement on each specific outcome, adjusting for age, gender and intervention assignment, as both intervention arms were included in the analysis.RESULTS: For every increase in total impulsiveness score by one standard deviation, the odds of experiencing clinically meaningful improvement decreased by 29% ( = 0.71, 95% CI, 0.55 to 0.91) on the clinical dimension and by 53% ( = 0.47, 95% CI, 0.32 to 0.68) on the existential dimension. However, changes in outcomes pertaining to physical, functional, criminological, and social dimensions were not significantly influenced by impulsiveness.CONCLUSIONS: Findings highlight the importance of addressing impulsiveness in the context of recovery-oriented interventions for homeless people with mental illness. Further research may be required to improve interventions that are responsive to unique needs of impulsive individuals to support clinical and existential recovery.
