This is a preliminary study investigating the risks associated with smartphone addiction by personality and type of phone. The results relate to personal background, personality, smartphone usage, smartphone satisfaction, level of exposure to risks, and correlations between the variables. A significant but partial correlation was found between personality and smartphone addiction, satisfaction, and level of risk. Smartphone addiction was found to be positively correlated with extraversion (r = .21, p < .01). Satisfaction was found to be correlated positively with extraversion (r = .28, p < .01), agreeableness (r = .41, p < .01), and conscientiousness (r = .38, p < .01), and negatively with emotional stability (r = -.57, p < .01). Risk was found to be negatively correlated with agreeableness (r = -.17, p < .05). Differences between types of phone in satisfaction, risk, and smartphone addiction were examined. A significant correlation (F(4, 145) = 2.96, p < .05) was found in the level of smartphone addiction, but no differences were found in smartphone satisfaction or the level of risk associated with smartphones (F(4, 145) = 2.96, p > .05 and F(4, 145) = .45, p > .05, respectively). According to the results, it seems that personality greatly affects phone usage and exposure to risks, regardless of the type of phone, and that reducing smartphone usage may be beneficial. However, further research using larger study samples is needed to confirm this.
