No mobile, no life: Self-perception and text-message dependency among Japanese high school students

A survey was conducted to investigate how self-perception of text-message dependency leads to psychological/behavioral symptoms in relation to personality factors. Japanese high school students completed a self-report questionnaire measuring frequency of text-messages, self-perception of textmessage dependency, psychological/behavioral symptoms, extroversion and neuroticism. Self-perception of text-message dependency was composed of three factors: perception of excessive use, emotional reaction, and relationship maintenance. Although message frequency was significantly related to psychological/behavioral symptoms, this effect was qualified by self-perception and personality factors. In particular, self-perception of text-message dependency strongly affected psychological/ behavioral symptoms. Importance of distinction between extroverted and neurotic text-message dependency through the process of self-perception of maladaptive behavior is discussed. 2007 Elsevier Ltd. All rights reserved.
