We applied the strength-energy model of self-control to understand the relationship between self-control and young athletes' behavioral responses to taking illegal performance-enhancing substances, or "doping." Measures of trait self-control, attitude and intention toward doping, intention toward, and adherence to, doping-avoidant behaviors, and the(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)
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)
Drawing from a three-factor model of organizational commitment, we sought to provide validity evidence for a multidimensional conceptualization designed to capture adolescent athletes' commitment to their coach-athlete relationship or their team. In Study 1, 335 individual-sport athletes (Mage = 17.32, SD = 1.38) completed instruments assessing affective,(More)
Recent studies of coach-athlete interaction have explored the bivariate relationships between each of the tripartite efficacy constructs (self-efficacy; other-efficacy; relation-inferred self-efficacy, or RISE) and various indicators of relationship quality. This investigation adopted an alternative approach by using cluster analyses to identify tripartite(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)
Although inoculation messages have been shown to be effective for inducing resistance to counter-attitudinal attacks, researchers have devoted relatively little attention toward studying the way in which inoculation theory principles might support challenges to psychological phenomena other than attitudes (e.g., self-efficacy). Prior to completing a(More)
Sustained attention has been devoted to studying the factors that support (or thwart) individuals' enjoyment of, interest in, and value judgments regarding their exercise activities. We employed a resistance-inducing (i.e., inoculation theory) messaging technique with the aim of protecting these desirable perceptions in the face of environmental conditions(More)
Inoculation theory, a theory of conferring resistance to persuasive influence, has established efficacy as a messaging strategy in the health domain. In fact, the earliest research on the theory in the 1960s involved health issues to build empirical support for tenets in the inoculation framework. Over the ensuing decades, scholars have further examined the(More)
This study subjectively assessed sleep quality and quantity, state anxiety and electronic device use during a 7-day training week (TRAIN) and a 7-day competitive tournament (COMP). Eight state-level netball players used wrist-watch actigraphy to provide indirect sleep measures of bedtime, wake time, sleep duration, sleep onset latency, sleep efficiency,(More)
