The relationships between the three syndromes of agitated behavior aggressive, physically nonaggressive, and verbally agitated) and three aspects of past personality (exposure to stress, history of a mental disorder, and leisure habits) were examined in 408 nursing home residents. Results showed that residents who had experienced the following stressful events during their lives — a life-threatening experience, separation from spouse, retirement, financial problems, and immigration — exhibited more physically nonaggressive behaviors (such as, pacing). Residents who had not experienced the stressful event of relocation manifested more aggressive (e.g., hitting) and physically nonaggressive behaviors. Neither history of a mental disorder nor past preferences for leisure activities were found to be related to agitated behaviors manifested by nursing home residents. Possible explanations for these results are discussed.
