PENGARUH OPENNESS TERHADAP AKTIVITAS FISIK MELALUI MEDIASI OTONOMI PADA DEWASA MUDA

Indonesia is considered a country with considerably low physical activity, therefore, it is necessary to promote physical activity to prevent degenerative diseases and death at a young age. Personality trait is considered a strong psychological factor in identifying physical activity. Recent research shows that the openness personality trait significantly influences physical activity. Openness is described as being open to accept various ideas and experiences, and is able to appreciate its diversity. Openness with the characteristics of being open allows individuals to receive information about the importance of physical activity, so that they are more active in carrying out activities. However, the effect of openness is inconsistent with some findings, so another variable is considered, such as autonomy which mediates this relationship. Autonomy is the degree to which individuals voluntarily choose to perform certain behaviors, when motivation to carry out behavior originates from within, this makes individuals maintain a behavior better. Autonomy is considered capable of increasing physical activity, because internal motivation (autonomy) is needed to maintain consistency in physical activity. This study aims to examine the mechanism of the relation between openness and physical activity through autonomy mediation. The study was conducted through self- reporting in 59 young adult men and 144 young adult women aged 20-40 years. Through analysis of the mediation process (Hayes), it is found that openness significantly affected physical activity when mediated by autonomy.Keywords: openness, autonomy, physical activity, young adults
