Intergenerational Hazardous Alcohol Use and Area Factors: The HUNT Study, Norway
2015
Alcohol use among adolescents has been found to be associated with parental alcohol abuse, but it's relation to more prevalent forms of hazardous drinking patterns among parents has been less explored. Few studies have included area factors when investigating alcohol use across generations.The aims of this study were to investigate whether adolescent intoxication was associated with parental heavy episodic drinking (HED) and intoxication, area-level socioeconomic status (SES), and rates of area-level HED.General Estimation Equations (GEE) was applied to analyze data from the Nord-Trøndelag Health Study (2006-08) including 2,306 adolescents. Adolescent alcohol use was defined by self-reporte…
Self-persuasion on Facebook increases alcohol risk perception
2018
Contains fulltext : 198083.pdf (Publisher’s version ) (Closed access) In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments. They either generated their own arguments with or without posting them, or read those present in the group with or without posting that they had read them. Next, participan…
Effects of whole-body vertical shock-type vibration on human ability for fine manual control
1991
The effects of vertical (z-axis) whole-body shock-type vibration on the ability for fine manual control were examined. The amplitudes and frequency of the shocks was varied, but a constant frequency-weighted acceleration of 1.25 m/s2 r.m.s. was maintained. The examination of the shock's effects was carried out using an experimental system that simulated the actual workplace of earth-moving machinery. Control was measured using a first-order pursuit tracking-test, in which a seated subject was asked to use both hands to direct a cursor on a monitor using a steering wheel. Although the magnitude of shocks (peak amplitude of 6-10 m/s2) and the number of shocks per unit time (shock cycle of 10-…
Examination of the risk factors associated with injured recreational padel players in Spain.
2017
BACKGROUND: Padel (called paddle in North America) is a relatively new racquet sport, with steady participation increases over the past 50 years. However, there is a need for data examining injury and associated risk factors. The study examined how intrinsic (e.g. age and sex) and extrinsic factors (e.g. padel participation and equipment) were associated with injury in recreational padel players. METHODS: A self-administered questionnaire completed by 80 recreational padel players between September 2014 and March 2015 acquired data on: respondent demographics and padel-related activities; the number of injuries within the past year; characteristics of the last injury sustained; and extrinsi…
Relationship between insight, violence and diagnoses in psychotic patients
2010
Abstract Introduction Lack of insight is a common clinical problem in psychiatric patients, but few times has been properly studied until recently. Patients with good insight tend to show a better treatment adherence with a better prognosis and show less hostility. This study aims to investigate whether there is a relationship between the hostility degree and insight or not and to analyse if there are insight quantitative differences between the patients regarding their diagnoses. Method One hundred and sixty-eight psychotic patients were studied (including 86 patients with schizophrenia and 43 with bipolar disorder). PANNS P7 (hostility) item and G14 (poor impulse control) were analysed in…
Heart rate variability related to effort at work
2011
Changes in autonomic nervous system function have been related to work stress induced increases in cardiovascular morbidity and mortality. Our purpose was to examine whether various heart rate variability (HRV) measures and new HRV-based relaxation measures are related to self-reported chronic work stress and daily emotions. The relaxation measures are based on neural network modelling of individual baseline heart rate and HRV information. Nineteen healthy hospital workers were studied during two work days during the same work period. Daytime, work time and night time heart rate, as well as physical activity were recorded. An effort-reward imbalance (ERI) questionnaire was used to assess ch…
Relationships of working conditions, health problems and vehicle accidents in bus rapid transit (BRT) drivers
2018
Background The aim of this study was to estimate accident risk rates and mental health of bus rapid transit (BRT) drivers based on psychosocial risk factors at work leading to increased stress and health problems. Methods A cross-sectional research design utilized a self-report questionnaire completed by 524 BRT drivers. Results Some working conditions of BRT drivers (lack of social support from supervisors and perceived potential for risk) may partially explain Bogota's BRT drivers' involvement in road accidents. Drivers' mental health problems were associated with higher job strain, less support from co-workers, fewer rewards and greater signal conflict while driving. Conclusions To preve…
Spanish validation of the mindful organizing scale: A questionnaire for the assessment of collective mindfulness
2018
Abstract Introduction Mindful organizing (also known as collective mindfulness) is a team level construct that is said to underpin the principles of high-reliability organizations (HROs), as it has shown to lead to almost error-free performance. While mindful organizing research has proliferated in recent years, studies on how to measure mindful organizing are scarce. Vogus and Sutcliffe (2007) originally validated a nine-item “Mindful Organizing Scale” but few subsequent validation studies of this scale exist. The present study aimed to validate a Spanish version of the Mindful Organizing Scale. Method The sample included 47 teams (comprising of a total of 573 workers with an average team …
Effects of alertness management training on sleepiness among long-haul truck drivers : a randomized controlled trial
2018
Education is a frequently recommended remedy for driver sleepiness in occupational settings, although not many studies have examined its usefulness. To date, there are no previous on-road randomized controlled trials investigating the benefits of training on sleepiness among employees working in road transport. To examine the effects of an educational intervention on long-haul truck drivers' sleepiness at the wheel, amount of sleep between work shifts, and use of efficient sleepiness countermeasures (SCM) in association with night and non-night shift, a total of 53 truck drivers operating from southern Finland were allocated into an intervention and a control group using a stratified random…
Understanding the consequences of victory amongst sport spectators: The mediating role of BIRGing.
2016
Prior work on the relationships between team identification and spectators' reactions to one's team victory has largely neglected the potential effects of mediating variables. In this research, we proposed that the process of Basking in Reflected Glory [BIRGing - the tendency to reduce the distance between oneself and one's team; Cialdini, R. B., Bordon, R. J., Thorne, A., Walker, M. R., Freeman, S., & Sloan, L. R. (1976). Basking in reflected glory: Three (football) field studies. Journal of Personality and Social Psychology, 34, 366-375] would lead spectators to almost take ownership of victories and share its benefits, thereby impacting their sense of national belonging in a positive man…
