Behavioral Gerontology

Description of Strategy

Behavioral gerontology is the application of behavioral principles to the problems of older adults. Though considerable work in behavioral gerontology has addressed basic research questions (e.g., the nature of dependency among nursing home residents, extent of new learning among Alzheimer's patients), most efforts in behavioral gerontology have focused on behavioral assessment, behavioral intervention, and a combination of the two. Behavioral gerontology began in the 1960s and early 1970s, with work by individuals such as Cautela, Hoyer, Lindsley, Risley, Baltes, and Pinkston. Though the same principles of behavior are applied to older adults as to younger adults and children, problems addressed with older adults are typically more complex and often unique to older adults. This is particularly the case with older adults who have experienced physical and cognitive decline.

Research Basis

A moderate amount of research has been conducted in behavioral geronotology, though many questions remain unanswered. Research areas, target problems, and interventions will be discussed by problem area, with an emphasis on clinical gerontology.

Self-Care

Self-care behaviors, including feeding/eating, ambulating, and maintaining personal hygiene may drop from an older adult's behavioral repertoire as a result of the progression of a disease or health problem or simply because these behaviors are no longer reinforced by environmental contingencies. Several studies have demonstrated the effectiveness of employing contingent positive reinforcement (e.g., praise) for eating combined with a time-out procedure for food refusal. Other interventions have incorporated prompting and praise for ambulation independent of a wheelchair and/or reinforcement for distance walked. Employment of token economies has proven effective as a method for reinforcing performance of personal hygiene tasks, including bathing, toileting, and oral hygiene. In addition to interventions based on reinforcement of the self-care behavior, other successful interventions have emphasized skills training involving instruction, modeling, and behavioral rehearsal.

Social Behavior

Social Skills

As opportunities for social interaction (e.g., job, school) decrease with age, older adults may find it difficult to interact socially and, as a result, lose social skills that were once a part of their behavioral repertoires. Social withdrawal is also common in older adults due to restraints in mobility or loss of friends and loved ones. Social skills training is a behavioral intervention that involves instruction, modeling of social behavior, behavioral rehearsal or role playing, feedback, and reinforcement of social interaction. Several studies have demonstrated that through social skills training, community-dwelling and institutionalized older adults were able to develop or fine-tune interpersonal skills that enhanced the quality and frequency of interactions with others.

Dependency

Older adults, especially those in nursing homes or institutional settings, must frequently rely on others for assistance with tasks, ranging from transportation to personal hygiene. As dependency on others grows, researchers have found that caregivers may inadvertently reinforce dependency by offering support, such as attention for dependent behavior, while ignoring independent behavior. This, in turn, may act as a catalyst for further functional decline. Behavioral interventions have proven useful as a means of breaking this cycle. Interventions have typically focused on changing caregiver responses to older adults' independent and dependent behaviors, to promote as much autonomy as possible in the older adult. Numerous studies have demonstrated that through caregiver training involving communication skills, knowledge about aging, and basic behavioral principles, caregivers can successfully alter their behaviors, which, in turn, encourages independence in nursing-home residents.
