The aim of this study was to evaluate the effect of PST on performance, retention, and transfer under pressure of novice badminton players. 40 novice badminton players were randomly assigned to experimental (20 participants) and placebo-control (20 participants) groups. In acquisition and retention tests, short and long service, toss clear and drop shots were used; in transfer under pressure test, notational analysis was applied. All participants acquired specific badminton skills in 24 sessions over three months. In addition to specific badminton skills, the experimental group received the specific package of PST during 24 sessions (each session 20 min.) while placebo-control group received the same number of sessions about general information on badminton. The results of mixed ANOVA indicated that in all tests, the scores of experimental group were significantly higher than those of the placebo-control group, which indicated the effectiveness of PST on performance and learning of novice male badminton players. The results of this study extended the effectiveness of PST to learning new motor skills.

The aim of this study was to determine the validity and reliability of the Persian version of sport perfectionism scale of Dun et al. (2006). To determine the construct validity of the questionnaire, 393 (230 male and 163 female) athletes with different skill levels (novice, non-elite and elite) in 10 team and individual sports were selected by random sampling method and then completed the questionnaire. For this purpose, three sport psychologists and three English teaching experts translated the questionnaire into Persian by translation - back translation method. Then, content and face validity of the Persian version was confirmed (CVI=0.89, VCR=0.93). Confirmatory factor analysis (CFA) based on structural equations model was used to determine the construct validity of the questionnaire; Cronbach alpha coefficient was used to determine internal consistency of the questionnaire and intra-class correlation coefficient under test-retest method with a 2-week interval was used to study temporal reliability of items. The results showed that the primary model of sports perfectionism scale did not support the favorable fit and thus did not confirm the construct validity of the primary model (30 questions). But after eliminating three problematic questions, the second model with 27 questions had acceptable fit indexes (RMSEA=0.08, CFI=0.87), internal consistency and temporal reliability indicating good validity and reliability of the modified Persian version (27 items) of sport perfectionism scale. Therefore, the Persian version of the sport perfectionism scale (modified model of 27 questions) can be used to study and evaluate the personality traits of Iranian athletes.
