Planning bridges the intention-behaviour gap: age makes a difference and strategy use explains why.

Area of Science:

• Behavioral Science
• Psychology
• Gerontology

Background:

• Bridging the intention-behavior gap is crucial for promoting physical activity.
• The effectiveness of planning in facilitating behavior change may vary with age.
• Selection, optimization, and compensation (SOC) strategies are proposed mechanisms for age-related differences in behavior regulation.

Purpose of the Study:

• To investigate age-differential associations between intentions, planning, and physical activity.
• To examine if the effectiveness of planning in bridging the intention-behavior gap increases with age.
• To explore SOC strategies as underlying mechanisms for age differences in physical activity behavior.

Main Methods:

• A sample of 265 employees (aged 19-64) from a national railway company participated.
• Intentions, planning, SOC strategy use, and physical activity were measured at baseline and 1-month follow-up.
• Path models were utilized to test hypotheses regarding mediation and moderation effects.

Main Results:

• Age significantly moderated the relationship between planning and physical activity, with planning being a stronger predictor in older individuals.
• SOC strategy use mediated the interaction between age and planning in predicting physical activity.
• The intention-behavior link for physical activity was stronger in older adults, mediated by planning and SOC strategies.

Conclusions:

• Behavior regulation mechanisms differ between young and middle-aged individuals regarding physical activity.
• Planning and SOC strategies play a key role in promoting physical activity, especially in older adults.
• Interventions aimed at increasing physical activity should consider age-specific strategies for behavior regulation.
