Hoarding Disorder is a condition often referred to occupational therapy for comprehensive assessment and intervention, however the strategies that occupational therapy professionals use in the clinical management of hoarding behaviors is poorly understood. The purpose of this mixed methods survey design research was to collect and analyze information on the beliefs, attitudes, and perceptions of common and effective intervention techniques currently used among occupational therapy professionals to address hoarding behaviors. A total of 18 (n = 18) responding occupational therapy professionals met inclusion criteria. Occupational therapy professionals universally indicated that environmental modification strategies were utilized as an intervention to manage hoarding behaviors, and the majority of participants also indicated the use of ADL training, IADL training, household mobility training, occupation-based therapeutic activity, personal safety training and self-management training as interventions for Hoarding Disorder. Regression analysis between the perceived effectiveness of a given intervention and the reported frequency of how often the intervention was used indicated that occupational therapy professionals found that the following interventions were generally most effective for the management of Hoarding Disorder: environmental modification, <i>rs</i>(18) =.550, <i>p</i> =.018, VS-MPR = 5.09; personal safety training, <i>rs</i>(18) =.543, <i>p</i> =.020, VS-MPR = 4.70; creative expression activities, <i>rs</i>(18) =.624, <i>p</i> =.006, VS-MPR = 11.98; ADL training, <i>rs</i>(18) =.412, <i>p</i> =.066, VS-MPR = 2.05; self management training, <i>rs</i>(18) =.443, <i>p</i> =.075, VS-MPR = 1.89; and occupation-based therapeutic activities, <i>rs</i>(18) =.444, <i>p</i> =.063, VS-MPR = 2.11. The results of this study affirm that occupational therapy professionals generally find complex systems of techniques as more effective than single techniques for treating those with hoarding disorders, however further research is needed to better understand which occupational therapy assessments and interventions work well together as effective treatment systems.
