Predicting physical activity by the personality styles of the five-factor model.

Area of Science:

• Psychology
• Behavioral Science
• Health Psychology

Background:

• Established links exist between broad personality traits and physical activity (PA).
• Previous research often treats personality traits as independent, potentially overlooking complex interactions.
• The heterogeneity in personality-PA relationships necessitates exploring trait combinations and specific facets.

Purpose of the Study:

• To investigate how personality trait combinations (styles) and specific facets relate to physical activity.
• To determine if non-additive effects between personality traits explain variance in PA.
• To explore the role of narrow personality facets in PA engagement.

Main Methods:

• Utilized data from the University of North Carolina Alumni Heart Study, including the NEO Personality Inventory (NEO-PI-R).
• Employed correlational analyses for broad personality domains and PA.
• Applied multinomial logistic regression to examine associations between PA and personality trait pairs, controlling for covariates.

Main Results:

• Lower neuroticism, lower agreeableness, and higher conscientiousness predicted increased PA.
• The combination of high extraversion and high openness was associated with higher PA.
• Specific trait combinations, such as low extraversion/high agreeableness and low extraversion/low conscientiousness, were linked to reduced PA.
• A specific facet of extraversion (activity) emerged as a significant driver of extraversion-PA associations.

Conclusions:

• Personality traits interact, influencing physical activity levels in non-additive ways.
• Assessing personality styles can identify individuals prone to physical activity avoidance.
• Personalized interventions targeting personality styles may enhance PA engagement.
