Geriatric Disorder
Conditions
Brief summary
This study examines the short- and long-term-effects of different repeated frames in which an exercise program is offered on behavior (i.e., frequency of exercise) and motivation (i.e., autonomous/controlled) in older people (65+). The frames are manipulated experimentally as either prevention focused (e.g., to prevent worse health), promotion focused (e.g., to gain better health) or neutral (control condition).
Interventions
BEHAVIORALRegulatory frame: prevention
Exercise program presented as preventing deterioration.
BEHAVIORALRegulatory frame: promotion
Exercise program presented as promoting improvement.
BEHAVIORALRegulatory frame: not implied
Exercise program presented without implied consequences.
