Temperament profile and its association with the vulnerability to smartphone addiction of medical students in Indonesia

Abstract Temperament profiles of an individual with high novelty seeking and low harm avoidance have been reported to be related to substance addiction, but smartphone addiction could be different from substance addiction. Medical students have high exposure to smartphone use. Screening their risk of smartphone addiction based on the temperament profile may help in deciding best prevention approach. This research aimed to examine the temperament profile and its association with vulnerability to smartphone addiction of medical students in Jakarta, Indonesia. The research was conducted with cross sectional design and simple random sampling. The Temperament and Character Inventory and the Smartphone Addiction Scale were used to measure desired outcomes. Logistic regression analysis was performed to identify the relationship between demographic factors, pattern of smartphone use, temperament type, and vulnerability to smartphone addiction. Of the 185 samples, most subjects have low novelty seeking, high reward dependence, and high harm avoidance. The average smartphone usage in a day was 7.94 hours (SD 3.92) with the initial age of smartphone usage was 7.58 years (SD 2.43). The respondents used smartphone for communication and accessing social media. High harm avoidance temperament was significantly associated with risk of smartphone addiction with OR 2.035; 95% CI 1.119 to 3.701). This study shows that smartphone addiction has similarities with other behavior addictions. Harm avoidance temperament is associated with the risk of smartphone addiction. Screening on risk of smartphone addiction based on temperament type should be done on medical students.
