Drinking and Swimming: Investigating Young Australian Males' Intentions to Engage in Recreational Swimming While Under the Influence of Alcohol
ABSTRACT Drowning, a largely preventable problem, continues to be a serious issue worldwide, with young men particularly at risk. Alcohol and drugs are often present among young males and, particularly for males aged 18-34 years, alcohol is considered to be a significant risk factor for drowning. The current study aimed to understand the motivations guiding the intentions of young Australian men to engage in drinking and swimming, a behaviour not yet examined systematically. A cross-sectional correlational design was adopted to investigate the ability of the theory of planned behaviour (TPB) and additional variables to predict males' intentions to drink and swim. Males (N = 211) aged 18-34 years (Mage = 23.93, SD = 4.01) completed a survey either on-line or paper-based. The survey assessed the TPB constructs of attitude, subjective norm, and perceived behavioural control (PBC); and additional variables of group norms, anticipated regret, objective (i.e. swimming ability) and perceived (i.e. perceived severity and perceived susceptibility) risk perceptions, and past behaviour. Support was found for the TPB constructs of attitude and subjective norm, but not PBC, as well as the additional constructs of group norm, anticipated regret, objective risk, and past behaviour in predicting males' intentions to drink and swim; explaining an overall 76 % of variance. Knowledge gained from this study will help to inform resultant interventions designed to discourage alcohol use in, on, or around water and, thus, prevent drownings in this at risk group.

ABSTRACT: The use of the internet to access information is rapidly increasing; however, the quality of health information provided on various online sites is questionable. We aimed to examine the underlying factors that guide parents’ decisions to use online information to manage their child’s health care, a behaviour which has not yet been explored systematically. Parents (N = 391) completed a questionnaire assessing the standard theory of planned behaviour (TPB) measures of attitude, subjective norm, perceived behavioural control (PBC), and intention as well as the underlying TPB belief-based items (i.e., behavioural, normative, and control beliefs) in addition to a measure of perceived risk and demographic variables. Two months later, consenting parents completed a follow-up telephone questionnaire which assessed the decisions they had made regarding their use of online information to manage their child’s health care during the previous 2 months. We found support for the TPB constructs of attitude, subjective norm, and PBC as well as the additional construct of perceived risk in predicting parents’ intentions to use online information to manage their child’s health care, with further support found for intentions, but not PBC, in predicting parents’ behaviour. The results of the TPB belief-based analyses also revealed important information about the critical beliefs that guide parents’ decisions to engage in this child health management behaviour. This theory-based investigation to understand parents’ motivations and online information-seeking behaviour is key to developing recommendations and policies to guide more appropriate help-seeking actions among parents.BMC Health Services Research 04/2015; 15(1).

ABSTRACT: To examine a mechanism by which social cognitive factors may predict fruit and vegetable consumption in long-haul truck drivers. Dietary self-efficacy, positive outcome expectancies, and intentions were assessed in 148 Australian truck drivers, and 1 week later they reported their fruit and vegetable consumption. A theory-guided sequential mediation model was specified that postulated self-efficacy and intention as mediators between outcome expectancies and behavior. The hypothesized model was confirmed. A direct effect of outcome expectancies was no longer present when mediators were included, and all indirect effects were significant, including the 2-mediator chain (β = .15; P < .05; 95% confidence interval, 0.05-0.32). Truck drivers who expected benefits from dietary change, felt confident about being capable to do so, and formed an intention were likely to report larger amounts of fruit and vegetable intake. The results suggest that the role of outcome expectancies and self-efficacy are important to consider for understanding and predicting healthy eating intentions in truck drivers.
