Adherence to Personal Resolutions Across Time, Culture, and Goal Domains

Area of Science:

• Psychology
• Behavioral Science

Background:

• Goal setting is common, but follow-through is challenging.
• Long-term behavior change requires understanding adherence predictors.
• Distinguishing between intrinsic and extrinsic motivation is key.

Purpose of the Study:

• To determine whether intrinsic or extrinsic motivation better predicts long-term goal adherence.
• To investigate the causal role of intrinsic motivation in sustained goal pursuit.
• To inform interventions aimed at improving goal achievement.

Main Methods:

• A year-long longitudinal study with U.S. adults setting New Year's resolutions.
• Cross-cultural replication with adults in China.
• Objective measurement of goal adherence using step counts over two weeks.
• Experimental manipulation to assess the causal impact of motivation type.

Main Results:

• Intrinsic motivation predicted adherence to goals more strongly than extrinsic motivation.
• Findings were consistent across different cultural contexts and objective adherence measures.
• Increasing intrinsic motivation led to greater goal adherence.

Conclusions:

• Intrinsic motivation is a superior predictor of long-term goal adherence compared to extrinsic motivation.
• Intrinsic motivation plays a causal role in enhancing sustained goal pursuit.
• Interventions should focus on fostering intrinsic motivation for effective behavior change.
