The purpose of this study was to explore elite coaches' perceptions of how they can both facilitate and impede the development of key mental toughness characteristics in the context of Australian football. Eleven coaches from a previous study (Gucciardi, Gordon, & Dimmock, 2008) were re-interviewed and the transcribed verbatim data were analysed using(More)
This study examined the effect of motivational primes on participants (N = 171) during a cycling task. Relative to participants primed with a controlled motivational orientation, it was hypothesized that participants primed for autonomous motivation would report greater feelings of enjoyment, effort, and choice in relation to the cycling activity and report(More)
Although researchers have experimentally examined the mechanisms underlying pressure-induced forms of suboptimal performance, or "choking under pressure," there is a lack of research exploring the personal experience of this phenomenon. In an attempt to fill this void in the literature, this study explored experienced golfers' perceptions of the choking(More)
OBJECTIVES Evidence suggests that competitive athletes returning to sport following injury rehabilitation may experience a range of psychosocial concerns. The purpose of this paper is to review some of the psychosocial stresses common among returning athletes and to provide practitioner strategies for enhancing recovery outcomes.

BACKGROUND Despite the well-established benefits of exercise during pregnancy, many women remain inactive. This may be related, in part, to women's beliefs about exercise in pregnancy, which are likely influenced by cultural background. Accordingly, the aim of this study was to compare attitudes, subjective norms, and perceived behavioural control toward(More)
OBJECTIVES Motivation in sport has been frequently identified as a key factor of young athletes' intention of doping in sport, but there has not been any attempt in scrutinizing the motivational mechanism involved. The present study applied the trans-contextual model of motivation to explain the relationship between motivation in a sport context and(More)
PURPOSE Within supervised rehabilitation programs, Lent and Lopez (2002) proposed that clients and therapists develop a "tripartite" network of efficacy beliefs, comprising their confidence in their own ability, their confidence in the other person's ability, and their estimation of the other person's confidence in them. To date, researchers have yet to(More)
This study was a preliminarily investigation into the prevention of unintentional doping on the basis of self-determination theory (SDT). Specifically, we examined the relationship between athletes' motives for doping avoidance and their behavior when offered an unfamiliar food product. Participants were young Australian athletes (n = 410) that were offered(More)
Objectives: Motivational and self-presentational processes pervade all aspects of our lives including exercise behaviors. Furthermore, trait perfectionism has been shown to heighten self-presentational tendencies and energize achievement striving (Flett & Hewitt, 2002; Hewitt et al., 2003). How maladaptive and adaptive perfectionism traits relate to these(More)
Physical activity theories have almost exclusively focused on conscious regulatory processes such as plans, beliefs, and expected value. The aim of this review was to aggregate the burgeoning evidence showing that physical activity is also partially determined by non-conscious processes (e.g., habits, automatic associations, priming effects). A systematic(More)
