Abstract
INTRODUCTION: This study tested whether affective attitude toward physical activity (PA) acts as a boundary condition for the cognitive attitude-behavior link in adolescents. METHODS: Participants were 1,849 middle- and high-school students in Shanghai, China (51% male; Mage = 15.12). Affective and cognitive attitudes were assessed with semantic differential scales, and out-of-school PA behavior was assessed 5-7 days later. RESULTS: Confirmatory factor analysis supported distinct affective and cognitive attitude factors. Moderation analyses indicated a significant Cognitive × Affective interaction (β = .48, p < .01). Johnson-Neyman probing indicated that the cognitive attitude-PA association strengthened as affective attitude increased; in this sample, the conditional effect became statistically distinguishable from zero (α = .05) when affective attitude was in the mid-to- high range (approximately > 4.16 on the 7-point scale) and increased progressively at higher affective levels. DISCUSSION: These findings extend attitude-behavior models by indicating that affective evaluations condition the strength of the cognitive attitude-behavior association and generate a testable hypothesis for future intervention research-namely, that enhancing positive affective evaluations/enjoyment may increase the effectiveness of cognitive benefit messaging-which should be evaluated in experimental designs.
