The associations among type D personality and nomophobia, metacognitions about smartphone use, smartphone addiction in Chinese university freshmen: a two-wave study.

Objective: This study aimed to examine longitudinal associations of Type D personality and smartphone addiction, while also exploring the mediating roles of nomophobia and metacognitions about smartphone use. Methods: Type D Personality Scale-14 (T1), Nomophobia Questionnaire (T2), Metacognitions about Smartphone Use Questionnaire (T2) and Smartphone Addiction Scale Short Version (T2) were applied at two time points. 653 university freshmen (Mage= 18.56, SD = 0.65) from a university in China were surveyed. Results: (1) Type D personality was significantly and positively correlated with nomophobia, negative metacognition, and smartphone addiction. In contrast, the correlation between Type D personality and positive metacognition did not reach the significant level. (2) Compared with individuals with non-Type D personality, those with Type D personality scored significantly higher on nomophobia, negative metacognition, and smartphone addiction. However, the difference was not significant for positive metacognition. (3) Nomophobia and metacognitions about smartphone use fully mediated the relationship between Type D personality and smartphone addiction. While the mediating effects of nomophobia and negative metacognition were significant, the mediating effect of positive metacognition was not significant. Conclusions: Type D personality can not only affect smartphone addiction directly but also indirectly through nomophobia and negative metacognition. Therefore, to prevent and intervene in smartphone addiction, we can start from both affect (nomophobia) and metacognition (negative metacognitions about smartphone use). [ABSTRACT FROM AUTHOR]
