It Pays to Pay Attention: A Mindfulness-Based Program for Injury Prevention With Soccer Players

The aim of this study was to examine the extent to which a mindfulness-based program could reduce the number of sport injuries in a sample of soccer players. A total of 41 junior elite soccer players were randomly assigned to the treatment or the attentional control group. The treatment group took part in a 7-session program based on the mindfulness, acceptance, and commitment approach. The attentional control group was offered 7 sessions of sport psychology presentations with a particular focus on soccer. There were no statistically significant differences in injury rates between the two groups, U(39) = 149.50, z = ?1.77, p =.077, but there was a medium effect size (adjusted Cohen's d = ? 0.59), approx. 80% confidence interval for d [?0.37, ?0.74]. Moreover, 67% of the players in the mindfulness group remained injury free in comparison to 40% in the control group. This result implies that an intervention program focusing on strategies for improving attention could decrease injury risk. Recommendations include applying mindfulness exercises in athletes’ daily training to help lower injury risk.     

When Sport psychology consultants and graduate students are impaired: Ethical and legal issues in training and supervision

Abstract

Impaired sport psychology consultants, that is, professionals and graduate students whose behavior, inadequate training, personal situations, or psychopathology are having a negative influence on the delivery of services, have the potential to do harm to athlete-clients, damage their own professional standing, and bring disrepute to the field. The applied sport psychology literature is replete with guidelines and suggestions for referring athletes for counseling or psychotherapy when appropriate (e.g., Heyman & Andersen, 1998), but the ethical, legal, and procedural problems associated with sport psychology consultants whose training or mental conditions suggest the need for remediation, rehabilitation, or psychotherapy, and possible removal from seeing clients, has not been addressed. We describe a variety of situations where student and professional functioning might be impaired, discuss the possible ramifications (legal, ethical) of impairment, and provide suggestions for ways to proceed when sport psychology consultants are in psychological difficulty.     

Ethical considerations in the supervision of applied sport psychology graduate students

Abstract

Some of the most important relationships that a sport psychologist experiences in his or her career are between the supervisor and supervisee in applied practica and internships. These relationships may become models for future professional and ethical behavior with colleagues, students, and clients, and thus deserve careful examination. Ethics form a foundation for practice, and while classroom discussions of ethical issues help educate graduate students, the supervisor-supervisee relationship may provide a hands-on experience of ethical dilemmas and ethical problem solving. Ethics in supervisor-supervisee relationships cover at least two broad areas. First, there is the supervisor's monitoring and mentoring of ethical considerations in the supervisee's relationship with the athlete-client. Second, ethical questions arise in the relationship between the supervisor and the supervisee. The present paper includes discussion of general supervisory issues (e.g., modeling ethical behavior, helping develop counseling skills) and explores the specific ethical problems of referring for counseling, intimacy, and exploitation. Also, three case examples illustrate ethical concerns that may appear in the process of applied sport psychology supervision. Broadening education in ethical issues in supervision for both psychology and exercise science graduate programs may help future practitioners better serve their clients.     

Childhood Abuse Types and Physical Health at the Age of 24: Testing Health Risk Behaviors and Psychological Distress as Mediators

This study examines whether adult psychological distress and health risk behaviors mediate the relationship between childhood abuse and physical health in adulthood. A randomly selected population-based sample, with oversampling to include a one-third subgroup of former child protection cases, completed a structured interview. Questions pertained to childhood exposure to abuse, adult psychological distress, physical health, and health risk behaviors. Previous research using this sample had identified three abuse typologies: emotional abuse, sexual abuse, and polyvictimization (physical abuse, emotional abuse, and neglect). All three typologies were significantly associated with poorer self-reported physical health. Psychological distress and health risk behaviors partially mediated the relationship between nonabuse, sexual abuse, polyvictimization, and physical health, and fully mediated the relationship between emotional abuse and physical health. The results of this study indicate that health risk behaviors and symptoms of psychological distress could contribute to some of the long-lasting consequences of childhood abuse on adult physical health.     

Detection of collision events on curved trajectories: optical information from invariant rate-of-bearing change

Previous research (Andersen & Kim, 2001) has shown that a linear trajectory collision event (i.e., a collision between a moving object and an observer) is specified by objects that expand and maintain a constant bearing (the object location remains constant in the visual field). In the present study, we examined the optical information for detecting a collision event when the trajectory was of constant curvature. Under these conditions, a collision event is specified by expansion of an object and a constant rate-of-bearing change. Three experiments were conducted in which trajectory curvature and display duration were varied while time to contact, speed, and initial image position of the collision objects were maintained. The results indicated that collision detection performance decreased with an increase in trajectory curvature and decreased with a decrease in display duration, especially for highly curved trajectories. In Experiment 3, we found that the presentation of a constant rate-of-bearing change in noncollision stimuli resulted in an increase in the false alarm rate. These results demonstrate that observers can detect collision events on curved trajectories and that observers utilize bearing change information.     

The relational self: an interpersonal social-cognitive theory

The authors propose an interpersonal social-cognitive theory of the self and personality, the relational self, in which knowledge about the self is linked with knowledge about significant others, and each linkage embodies a self-other relationship. Mental representations of significant others are activated and used in interpersonal encounters in the social-cognitive phenomenon of transference (S. M. Andersen & N. S. Glassman, 1996), and this evokes the relational self. Variability in relational selves depends on interpersonal contextual cues, whereas stability derives from the chronic accessibility of significant-other representations. Relational selves function in if-then terms (W. Mischel & Y. Shoda, 1995), in which ifs are situations triggering transference, and thens are relational selves. An individual's repertoire of relational selves is a source of interpersonal patterns involving affect, motivation, self-evaluation, and self-regulation.     

When fit indices and residuals are incompatible

Standard chi-square-based fit indices for factor analysis and related models have a little known property: They are more sensitive to misfit when unique variances are small than when they are large. Consequently, very small correlation residuals indicating excellent fit can be accompanied by indications of bad fit by the fit indices when unique variances are small. An empirical example of this incompatibility between residuals and fit indices is provided. For illustrative purposes, an artificial example is provided that yields exactly the same correlation residuals as the empirical example but has larger unique variances. For this example, the fit indices indicate excellent fit. A theoretical explanation for this phenomenon is provided using relationships between unique variances and eigenvalues of the fitted correlation matrix.     

Perceptual information and attentional constraints in visual search of collision events

This study examined the detection of collision events when multiple moving objects were present in the scene. Observers were presented with displays simulating a 3-D environment with multiple moving objects. The authors examined the ability of observers to detect collisions using a signal-detection paradigm and a visual search paradigm. The results indicated that, overall, observers were quite accurate at detecting collisions. Observers used both expansion information and static position to detect collisions, with expansion information being the more important source. Singleton search conditions were not processed in parallel, and conjunction search conditions had poorer performance than singleton search conditions. In addition, reaction times were greater for target-present trials as compared with target-absent trials. The results are interpreted in terms of 4 visual search hypotheses for collision detection when multiple moving objects are present.
