Effect of Retraining Approach-Avoidance Tendencies on an Exercise Task: A Randomized Controlled Trial.

Area of Science:

• Behavioral Science
• Public Health
• Exercise Science

Background:

• Physical activity (PA) promotion and sedentary behavior (SB) reduction are public health priorities.
• Impulsive approach-avoidance tendencies (IAAT) influence both PA and SB, beyond reflective processes.
• Understanding IAAT is crucial for developing effective behavior change interventions.

Purpose of the Study:

• To test the efficacy of a computerized intervention targeting IAAT on exercise behavior.
• To investigate if training to approach PA and avoid SB increases exercise duration.

Main Methods:

• 115 participants were randomized into three groups: approach PA/avoid SB, approach SB/avoid PA, or a control.
• The primary outcome measured was the time spent engaged in moderate-intensity exercise.
• Impulsive approach-avoidance tendencies toward PA were assessed.

Main Results:

• The group trained to approach PA and avoid SB (ApPA-AvSB) spent significantly more time exercising than the group trained to approach SB and avoid PA (ApSB-AvPA).
• Sensitivity analyses showed the ApPA-AvSB group also exercised more than the control group, especially among less active individuals.
• IAAT towards PA decreased in the ApSB-AvPA group and tended to increase in the ApPA-AvSB group.

Conclusions:

• A single computerized IAAT intervention session can effectively alter impulsive tendencies towards PA.
• This intervention increases exercise duration, offering a promising strategy for promoting physical activity.
• Findings have implications for health behavior theories and the design of targeted interventions.
