The Mediation Role of Mobile Phone Addiction to the Relationship between Physical Activity and Autistic Traits among College Students

Abstract

This study taking physical activity (PA) as the independent variable and autistic traits (AQ) as the dependent variable, we explored the relationship between the three in depth, further verified the mediating role of mobile phone addiction (MPA ) between the two , and constructed a hypothesized mediation model of mobile phone addiction in the relationship between physical activity and autistic traits.Method: This study takes the characteristics and correlations of physical activity (PA), autistic traits (AQ) and mobile phone addiction (MPA) as the research objects, follows the principle of convenience sampling , and uses questionnaire survey method and mathematical statistics method to conduct a survey on Zhanjiang City, Guangdong Province. Three universities conducted stratified sampling , and finally conducted a survey and research on 382 college students . The " International Physical Activity Scale -Short (IPAQ -SF)", "Autism Trait Scale(AQ)" and "Mobile Phone Addiction Tendency Scale(MPATS)" were used. An electronic questionnaire produced by "Questionnaire Star" was used to conduct an online survey on college students' physical activity, autistic traits and mobile phone addiction tendencies, etc., and SPSS24.0 was used for statistical processing and analysis.Result:1. The BMI difference between PAand AQ of college students was significant (p < 0.01). 2. There was a significant difference between the PA level and the level of college students with high and low AQ (p < 0.01). 3. The results of correlation analysis showed that there was a significant negative correlation between PA and AQ (r = -0.48**, Sig.000) and MPA (r=-0.22**, Sig.000), and a significant positive correlation between AQ and MPA (r=0.37**, Sig.000). 4. PA had a significant mediating effect on AQ through MPA, and MPA had a significant mediating effect between PA and AQ; the direct effect of PA on AQ was significant; the total effect of PA on AQ was significant.Conclusion:1.Physical activity can significantly and negatively predict autistic traits and mobile phone addiction; 2. Mobile phone addiction significantly and positively predicts autistic traits ;3. Mobile phone addiction ranks between physical activity and autistic traits has a significant mediating effect.
