This study tested the utility of Morgan’s (1980) Mental Health Model and Hanin’s (1980) Zone of Optimal Function Model in an ecologically valid environment. A sample of 12 high-performance adult clay-target shooters were tested over an entire competitive season. Precompetitive mood states were assessed using Schacham’s (1983) short version of the Profile of Mood States (POMS; McNair, Lorr, & Droppleman, 1971). Results revealed partial support for Hanin’s model but no support for Morgan’s model. Discussion focuses on the importance of multiple assessments of precompetitive emotions, recognition of individual differences, and selection of a precise measure of sport performance.

The purpose of the present investigation was to compare Australian tennis coaches’ frequency of use, and perceived effectiveness, of 13 self-efficacy building strategies to those of American tennis coaches. Subjects were 60 Australian tennis coaches coaching at the club or state level. Results indicated that Australian coaches used all 13 strategies designed to enhance selfefficacy to a moderate degree and found these techniques to be at least moderately effective. The most often-used strategies to enhance self-efficacy, as well as those strategies found most effective, included encouraging positive self-talk, modeling confidence oneself, using instruction drills, using rewarding statements liberally, and using verbal persuasion. When comparing the results of the Australian and American coaches, few differences were found. However, the American coaches used more of the following self-efficacy strategies: conditioning drills, the modeling of other successful players, the emphasis that feelings of anxiety are not fear but are a sign of readiness, and the emphasis that failure results from lack of effort or experience and not from a lack of innate ability. Results are discussed in terms of Bandura’s self-efficacy theory and Weinberg and Jackson’s (1990) efficacy-building strategies used by American tennis coaches. Future directions for research are offered.

Eight international baseball pitchers were filmed in a laboratory while throwing from a pitching rubber attached to a Kistler force platform. Following a warm-up, all subjects threw fastballs (FB) until two strike pitches were assessed by an umpire positioned behind the catcher for both wind-up and set pitching techniques. Subjects then followed the same procedures for curveball pitches (CB). Both vertical (Z) and horizontal (Y) ground reaction force (GRF) data were recorded. A shutter correlation pulse was encoded so the temporal data from the film could be synchronized with the kinetic data from the force platform. Analysis of variance was used to analyze differences in force data at selected points in both pitching actions for both techniques. Vertical and horizontal GRFs increased from the first balance position to maximum levels at the cocked position for both techniques. Nonsignificant changes in GRF then occurred between the cocked position and front-foot landing. The Z GRFs were similar throughout the pitching action but higher in magnitude for the CB compared to the FB. Mean resultant forces were similar for the three fastest FB pitchers when compared to the three slowest pitchers. However, the slower group produced their peak resultant force earlier in the action, thus reducing the ability to drive over a stabilized front leg.

Hypnotic susceptibility and prior experience were investigated as correlates of flowlike states during exercise. Heart rate was also examined as a potential correlate of flow. Circuit trainers (N = 96) completed a 10-item flow questionnaire and recorded their heart rates as they moved between exercise stations. Results indicated that self-reports of flowlike states increased from early to late in the exercise sessions, but that the magnitude of change was greater for participants high in hypnotic susceptibility than for those low in hypnotic susceptibility. Prior experience was also significantly related to flow ratings, with participants having more than 6 months of prior experience providing higher ratings than those with less than 6 months of prior experience. No significant relationship was observed between exercise heart rate and self-reports of flow. The findings are discussed in relation to the model of flow proposed by Kimiecik and Stein (1992).

Sport performers (N = 213) completed either a questionnaire measure of dispositional optimism or a questionnaire measure of trait sport confidence and then provided information about how they cope with performance slumps. The use of task-focused, emotion-focused, and avoidance-oriented coping strategies was assessed with a slump-referenced version of the Coping Inventory for Stressful Situations (CISS; Endler & Parker, 1990a). Results indicated that both personality measures were positively related to the use of problem-focused strategies and negatively related to the use of emotion-focused strategies. These findings are discussed in relation to previous research on confidence in sport and a model of sport-related coping proposed by Hardy, Jones, and Gould (1996). Practical implications for the effective management of performance slumps are also addressed.

Field hockey players (n=39) assessed their own psychological strengths and weaknesses by rank-ordering various mental skills. Coaches (n=5) who had daily contact with these athletes ranked the same skills on the basis of their perception of the players’ strengths and weaknesses. Comparisons indicated that the specificity of the skills being ranked influenced the amount of agreement between the responses of players and coaches. When general categories of skills were ranked, there was very little consistency between the groups. When specific skills within the general categories were ranked, there was considerable consistency between the groups. The results are discussed in relation to the nature of the questions asked when designing mental training programs. It is suggested that consultants should take care to identify potential problems in terms of specific skills rather than general categories. By doing so, they may increase the likelihood of agreement about mental training needs and increase their effectiveness. The issue of conducting selfassessments via rating-scale and rank-order formats is also addressed. Problems that the consultant may encounter in the use of a rating-scale format are noted, and the potential advantages of a rank-order format are discussed.
