Principal Component Analysis of Lifestyle Factors Influencing Behavioral Intentions

Abstract

To promote environmentally conscious behavior, it is essential to understand individuals’ behavioral intentions in daily life. This study conducted a questionnaire survey using a five-point Likert scale with 2,000 participants, based on indicators of lifestyle values. Principal component analysis (PCA) identified ten components, which were then systematically organized. The results revealed a structural framework comprising three factors influencing behavioral intentions: (1) facilitators of environmentally conscious behavior (social interaction, personal experience, and nature), (2) inhibitors (convenience), and (3) situational factors that may lead to environmentally conscious behavior depending on conditions (social conformity, family, and nostalgia). Understanding this complex structure－comprising facilitation, inhibition, and situational variability－offers a renewed perspective on the challenges of promoting environmentally conscious behavior and provides insights for designing new sustainable lifestyles.
