- Description: Demonstrations of the CFA process in the context of imagery abilities and imagery use assessment are severely lacking. Presently, very few imagery measures from either general or sport psychology have had their factor structure confirmed using structural equation modeling to. Irrespective of the accepted difficulties in the assessment of the imagery process, understanding in the field can only be enhanced through the application of appropriate statistical tools to demonstrate the relationship between measured variables and latent constructs. This paper details the examination of the factor structures of the Sport Imagery Ability Measure (SIAM) and the Sport Imagery Questionnaire (SIQ), using structural equation modeling. Confirmatory models of the key characteristics of mental imagery in relation to sport are also discussed. The SIAM is a 48-item self-report measure that uses four sport-related scenes to examine the dimensional, sensorial, and emotional characteristics of generating images. The SIQ is a 30-item self-report measure that examines five characteristics associated with the cognitive and motivational aspects of imagery use. Participants (N = 514) from universities and elite sport groups in Australia, England, and Finland completed the measures. Confirmatory factor analyses of models proposed by the authors of each measure were conducted using AMOS 4.0 software. The SIAM threefactor model was a reasonable to good fit for the data with all fit indices except for the RMSEA (0.12) at or above accepted minima. A five-factor model tested for the SIQ did not result in as many acceptable fit indices, with only the RMSEA (0.07) indicating a good fit. Alternative models for both measures are examined and the implications of these findings in relation to both the evaluation and conceptualization of sport imagery are discussed.

- Description: Introduction: This study examined the effect of yoga on the state anxiety and mood states of athletes. Yoga has long been practised by athletes but its influence on the mood state of athletes has not been empirically examined. Method: Participants were 15 female netball players, aged between 18 and 27 years (M = 20.97, SD = 3.09) who completed the Abbreviated Profile of Mood States (APOMS) and the state anxiety inventory (A-State) before and after each of six yoga or strength and conditioning sessions completed one night per week. Participants acted as their own controls with all participants completing both treatments. The main hypothesis was that yoga participants would report significantly greater changes in mood state and state anxiety than strength and conditioning participants. Results: A One-Way Multivariate Analysis of Variance (MANOVA) indicated that yoga sessions had significantly greater pre to post test change on overall mood state and state anxiety compared to strength and conditioning sessions. In addition, on the subscales of the APOMS, yoga produced significantly greater pre to post test decreases on confusion and tension than strength and conditioning. Conclusion: Results support the use of yoga to positively enhance mood state and decrease state anxiety in athlete populations.Implications for coaches and athletes are discussed including the potential use of alternative and holistic training methods for the management of mood and anxiety. Future research directions are also discussed including investigating alternative approaches to the management of mood and anxiety in athletes and further investigation into the components of yoga.
