Sensation seeking, stress, and adolescent injuries: a test of stress-buffering, risk-taking, and coping skills hypotheses.

The potential stress-buffering effects of sensation seeking were assessed in a prospective study involving high school athletes. A significant positive relation between major negative sport-specific life events and subsequent injury time-loss occurred only for athletes low in sensation seeking. No evidence was obtained for a competing hypothesis that high sensation seeking would constitute an injury vulnerability factor by increasing risk-taking behaviors. Although low sensation seekers reported poorer stress management coping skills, there was no evidence that differences in coping efficacy mediated the injury vulnerability difference. Results indicate that sensation seeking is a stress-resiliency factor and suggest the utility of assessing relations between life stressors and outcomes that occur within the same environmental context.

Psychology of the young athlete. Stress-related maladies and remedial approaches.

This article has presented a theoretical framework for understanding the stress process. The conceptual model of stress specifies relations among situational, cognitive, physiologic, and behavioral factors. Each of these basic components of the model is assumed to be influenced by personality and motivational variables. At the situational level, stress involves the balance or imbalance between situational demands and the resources available to deal with them. However, these situational factors affect the person primarily through the intervening influence of cognitive processes. Among the most important of these processes are appraisal of (1) the situational demands, (2) available personal and social resources, (3) the possible consequences of failure to meet the demands, and (4) the perceived meaning of the consequences. A reciprocal relation exists between cognitive and physiologic processes; the nature of the appraisals influences the level of physiologic arousal that is likely to occur, and arousal in turn influences the ongoing appraisal process through physiologic feedback mechanisms. Finally, the behavioral component of the model includes the person's learned behavior tendencies, task-relevant skills, and social skills. Personality and motivational individual difference variables are important; they influence the kinds of situations to which people expose themselves, how they appraise themselves and the situations, how they react physiologically, and how they customarily respond at the behavioral level. With respect to the consequences of stress, mounting evidence suggests that a significant number of young athletes experience adverse psychological, behavioral, and health-related effects. In fact, because of anticipated stresses, some children decline to participate in the first place. Competitive stress detracts from enjoyment of sports, causes performance impairment, and contributes significantly to the drop-out rate in youth sports. Evidence also indicates that competitive stress can cause loss of sleep and put youngsters at greater risk for sustaining athletic injuries. However, although extremely high levels of stress are experienced by a minority of young athletes, the level of stress elicited by youth sports is generally no greater than that found in other achievement-oriented activities in which children participate. The conceptual model of stress not only provides a framework for identifying sources of stress, but also suggests foci for intervention strategies designed to reduce stress in youth sports. In this article, consideration has been given to prominent situational demands that contribute to competitive stress and to various approaches for counteracting the stress-inducing factors. Specifically, measures may be instituted that decrease situational demands associated with winning and losing, organization and administration of sport programs, coaching roles and relationships, and parent roles and responsibilities.(ABSTRACT TRUNCATED AT 400 WORDS)

Conjunctive moderator variables in vulnerability and resiliency research: life stress, social support and coping skills, and adolescent sport injuries.

In life event research relating to vulnerability and resilience factors, single moderator variables have typically been the focus of study. Little is known about the ways in which moderator variables may interact with one another to increase vulnerability or resilience. We propose a distinction between conjunctive moderation, in which multiple moderators must co-occur in a specific combination or pattern to maximize a relation between a predictor and an outcome variable, and disjunctive moderation, in which any one of a number of moderators maximizes the predictor-criterion relation. Our results indicate that social support and psychological coping skills are statistically independent psychosocial resources and that they operate in a conjunctive manner to influence the relation between life stress and subsequent athletic injury in adolescents. Only athletes low in both coping skills and social support exhibited a significant stress-injury relation, and in that vulnerable subgroup, negative major life events accounted for up to 30% of the injury variance. Methodological considerations in the assessment of conjunctive moderator effects are discussed.

Relationships among measures of preferred tempo and motor rhythm.

Male and female subjects (Ns = 100) performed an accuracy task involving consecutive arm swings at a self-paced tempo. Following this, the subjects performed a motor rhythm task keeping in cadence with audio-visual stimuli presented at their preferred tempo. Previous findings regarding the magnitude of individual differences in preferred tempo and within-individual variability were replicated, as was the absence of sex differences for these attributes. With regard to motor rhythm, the findings indicated that (a) constant and variable error, and not absolute error, were the appropriate measures of performance, (b) there were no sex differences either in spatial or temporal accuracy or in trial-to-trial consistency of performance, (c) substantial individual differences were present in rhythmic accuracy, as were moderate individual differences in variability, (d) neither rhythmic accuracy nor variability was appreciably related to preferred tempo, and (e) spatial and temporal accuracy are relatively independent components of rhythmic accuracy.

Preferred tempo in performance of repetitive movements.

Within- and between-S variability in performance of repetitive movements at a self-paced tempo was studied. Male and female Ss (Ns = 75) performed 36 consecutive arm swings at an individually chosen tempo. Differences between Ss' selected tempos of performance were considerably greater than the amount of variation in Ss' motor response times, indicating that individuals have preferred tempos of voluntary movement which differ from those of other individuals. No sex differences were evidenced in either preferred tempo or consistency of performance.
