Internet addiction among Norwegian adults: a stratified probability sample study

Most Norwegians are Internet users. We conducted a stratified probability sample study (Norway, 2007, age-group 16–74 years, N = 3,399, response rate 35.3%, 87.1% Internet users) to assess the prevalence of Internet addiction and at-risk Internet use by the Young Diagnostic Questionnaire (YDQ). The prevalence of Internet addiction (YDQ score 5–8) was 1.0% and an additional 5.2% were at-risk Internet users (YDQ score 3–4). Internet addiction and at-risk Internet use was strongly dependent on gender and age with highest prevalences among young males (16–29 years 4.1% and 19.0%, 30–39 years 3.3% and 10.7%). Logistic regression showed that male gender, young age, university level education, and an unsatisfactory financial situation were factors positively associated with "problematic Internet use" (at-risk and addicted use combined). Time spent on the Internet and prevalence of self-reported sleeping disorders, depression, and other psychological impairments increased linearly with YDQ score. Problematic Internet use clearly affects the lives of many people.     

Relationship between heart rate variability and cognitive function during threat of shock

The aim of the present study was to investigate the relationship between resting heart rate variability (HRV) and cognitive functions during threat of shock. A Continuous Performance Task and a Working Memory Task were used to measure cognitive functions. Sixty-five male participants from the Royal Norwegian Navy participated. HRV was measured during baseline, test conditions and recovery. Participants were randomly assigned into non-threat and threat groups. Based on the median split of the high frequency (HF) spectral power, groups were divided into two additional groups. Overall, the high HRV participants showed superior performance on cognitive tasks independent of non-threat or threat conditions. During threat condition the low HRV group showed improved performance. Thus, individuals with high HRV were more stress tolerant and resilient in the face of environmental changes. The results from the study might have implications with regard to performance in operational settings, but also for other fields of psychological research such as individual differences, anxiety and coping.     

Screening for drugs in oral fluid: Illicit drug use and drug driving in a sample of urban and regional Queensland motorists

Police services in a number of Australian states and overseas jurisdictions have begun to implement or consider random road-side drug testing of drivers. This paper outlines research conducted to provide an estimate of the extent of drug driving in a sample of Queensland drivers in regional, rural and metropolitan areas. Oral fluid samples were collected from 2657 Queensland motorists and screened for illicit substances including cannabis (delta 9 tetrahydrocannibinol [THC]), amphetamines, ecstasy, and cocaine. Overall, 3.8% of the sample (n = 101) screened positive for at least one illicit substance, although multiple drugs were identified in a sample of 23 respondents. The most common drugs detected in oral fluid were ecstasy (n = 53), and cannabis (n = 46) followed by amphetamines (n = 23). A key finding was that cannabis was confirmed as the most common self-reported drug combined with driving and that individuals who tested positive to any drug through oral fluid analysis were also more likely to report the highest frequency of drug driving. Furthermore, a comparison between drug vs. drink driving detection rates for one region of the study, revealed a higher detection rate for drug driving (3.8%) vs. drink driving (0.8%). This research provides evidence that drug driving is relatively prevalent on Queensland roads, and may in fact be more common than drink driving. This paper will further outline the study findings’ and present possible directions for future drug driving research.     

Exploring Internet Motives and Life Satisfaction Among Hungarian and Israeli Medical Students, Living in Hungary

Objective Using the Internet can influence psychological well-being, for instance life satisfaction has been negatively related to Internet uses. The first aim of this study was to compare the motives for Internet use and life satisfaction. The second aim was to explore nation- and gender-based differences in Internet uses. Method The questionnaires related to Internet motives and life satisfaction, and were filled out by 300 medical students, including 150 Israeli students (75 females, 75 males) and 150 Hungarian students (75 females, 75 males). Results In the Israeli and Hungarian sample, the entertainment motive was rated the highest while the escape motive was rated the lowest. There were significant differences between the Israeli male and female students in arousal and information-seeking, while for the Hungarian male and female students there were significant differences for pass time. Life satisfaction was higher in the Israeli sample. In both samples it was shown that the higher the life satisfaction was, the less likely the students were to use the Internet for companionship purposes. Again in both samples, a higher life satisfaction predicted less frequent use of the Internet for the social interaction motives.     

Moving Beyond Self‐Report: Implicit Associations about Death/Life Prospectively Predict Suicidal Behavior among Veterans

Reliance on self‐report limits clinicians' ability to accurately predict suicidal behavior. In this study the predictive validity of an objective measure, the death/suicide Implicit Association Test (d/sIAT), was tested among psychiatrically hospitalized veterans. Following acute stabilization, 176 participants completed the d/sIAT and traditional suicide risk assessments. Participants had similar d/sIAT scores regardless of whether they had recently attempted suicide. However, d/sIAT scores significantly predicted suicide attempts during the 6‐month follow‐up above and beyond other known risk factors for suicidal behavior (OR = 1.89; 95% CI: 1.15–3.12; based on 1SD increase). The d/sIAT may augment the accuracy of suicide risk assessment.     

EMPOWERING TOKEN WOMEN LEADERS

We hypothesized that, in a masculine task, only token women leaders who were empowered through position (by being appointed leader) and expertise (trained with task-relevant information) and legitimated by a male experimenter as credible would be more effective in influencing the performance of their all-male groups than appointed-only and appointed-trained leaders. Thirty women undergraduates each led a small group of male students on a moon survival task. The hypothesis was supported. Videotapes of group interactions revealed that appointed-trained leaders interrupted group members and used tentative tag questions in failed attempts to share their task-relevant knowledge. In addition, group members reported the most dissatisfaction with appointed-trained leaders who, without legitimacy, violated diffused gender roles by presuming to be expert on a masculine task. The importance of the organizational empowerment of token women is underscored.
