We examined the role of personality and self-esteem in university students' (N = 200) use of communication technologies. More disagreeable individuals spent increased time on calls, whereas extraverted and neurotic individuals reported increased time spent text messaging. More disagreeable individuals and those with lower self-esteem spent increased time using instant messaging (IM). For addictive tendencies related to communication technologies, more neurotic individuals reported stronger mobile phone addictive tendencies, while more disagreeable individuals and those with lower self-esteem reported stronger IM addictive tendencies.

In Australia, youth are the most prolific users of mobile phones, however, there is little research investigating this phenomenon. This paper reports a qualitative exploration of psychological factors relating to mobile phone use amongst Australian youth. 32 participants, aged between 16 and 24 years, took part in focus group discussions. Thematic data analysis focussed on identifying the psychological benefits arising from mobile phone use and whether mobile phone addiction was occurring amongst this group. Mobile phone use was believed to provide numerous benefits to users and is an intrinsic part of most young people's lives. It emerged that some young people are extremely attached to their mobile phone with symptoms of behavioural addiction revealed in participants' descriptions of their mobile phone use. The study provides a solid foundation for further work investigating addictive patterns of mobile phone use amongst youth.

Despite being identified as an unsafe (and, in some jurisdictions, illegal) driving practice, the psychological factors underlying people's decision to use their mobile phone while driving have received little attention. The present study utilised the theory of planned behaviour (TPB) to examine the role of attitudes, norms, control factors, and risk perceptions, in predicting people's intentions to use their mobile phone while driving. We examined the predictors of intentions to use a mobile phone while driving in general, and for calling and text messaging in 4 scenarios differing in descriptions of vehicle speed and time pressure. There was some support for the TPB given that attitudes consistently predicted intentions to drive while using a mobile phone and that pressure from significant others (norms) determined some phone use while driving intentions, although less support was found for the role of perceptions of control. Risk was not generally predictive of safer driving intentions. These findings indicate that different factors influence each form of mobile phone use while driving and, hence, a multi-strategy approach is likely to be required to address the issue.
