Abstract:This article examines the moderating effect of depression on interdisciplinary treatment approaches for behaviors in dementia. A secondary analysis of data collected on tailored treatment of 105 long-term care residents with dementia found a significant relationship between treatment and passivity (p < 0.001), treatment and agitation (p = 0.001), and the mediating effect of change in passivity on change in agitation (p < 0.001). The moderating effect of depression was found as a significant factor. For participants with depression and agitation, a significant change in passive behavior was related to significant change in agitated behavior. Thus, by focusing treatment on passivity, both types of neuropsychiatric behaviors improved. The implications of thoroughly assessing not only a behavior problem such as agitation but also other neuropsychiatric symptoms that complicate the delivery of the intervention are discussed.
Article:Approximately 5.2 million people in the United States have Alzheimer's disease or a related disorder (ADRD) (Alzheimer's Association, 2007). It is estimated that this number will grow to 7.7 million by the year 2030 and to 13.2 million by the year 2050 (Alzheimer's Association, 2007). The overall prevalence of ADRD doubles for every 5-year age group older than 65 (National Institute on Aging, 2010). It is well established that older adults with ADRD exhibit multiple behavioral and psychological symptoms such as agitation, passivity, and depression, which may decrease their levels of engagement in meaningful life experiences (Rabheru, 2004). Not only do these complex symptoms have an effect on engagement levels, they also increase patient and family distress and are difficult to manage across care settings (Harman et al., 2002; Janzing, Bouwens, Teunisse, Van't Hof, & Zitman, 1999).Older adults with multiple problems benefit from interdisciplinary person-centered approaches (Zimmerman et al., 2005). In this type of model, health care professionals from different disciplines are often cross trained and work together to provide integrated treatment approaches. Experts believe when professionals from different disciplinary backgrounds work together to combine their specialized disciplinary knowledge, concepts, and assessment tools for problem solving and decision making, the resulting outcome is much greater than the sum of the parts of any one discipline (Bermejo et al., 2009). Although there is some evidence (Callahan, 2006;Unutzer et al., 2002) that effective interdisciplinary teams are able to incorporate their collective discipline knowledge to problem solve in complex situations and produce better outcomes for patients in primary care, few studies exist that capture this in long-term care settings. It is unclear what the relationship is in individuals with depression and dementia experiencing neuropsychiatric behaviors.There is a dearth of research that examines the use of interdisciplinary intervention approaches to engage older adults with dementia, neuropsychiatric behaviors...
