The purpose of this study was to develop the Bowling AttentionInventory (BAI), which further could serve to facilitate teachingand training techniques in bowling. The BAI was comprised of fivesubscales: attention duration, attention flexibility, attentionintensity, attention selectivity and attention capacity. There were46 items which were measured by the Likert 5-point scale. The BAIcould be completed in about 10 minutes, The process of responseto the BAI was quite simple and does not need any furtherexplanation.350 bowlers in the preliminary test completed the item analyses.The process of standardization used 237 reliability samples, 271validity samples and 1110 norm samples, The data was analyzedthrough statistical analysis which derive the following results:1. Reliability: The Cronbach''s αcoefficients ranging from .55 to. 85. The two-week test-retest reliability coefficients ranging from .68 to .83 and the four-week test-retest reliability coefficients ranging from .41 to .66. The split-half reliability coefficient was .88.2. Content Validity: Interviewing 8 national bowling athletes, professors, coaches and subsequently 20 sports psychologists, test and statistical experts and national bowling athletes were invited to evaluate the contents of the scale. The content validity was established.3. Concurrent validity: The correlation between the cognitive, somative anxiety of CSAI-2 with BAI was -.19 and -.18 respectively. The correlation between self-confidence and BAI was .53. The correlation between bowling seniority and BAI was .26. The correlation between the number of weekly practices and BAI was .23. The correlation between bowling score and BAI was .53. The correlation between the number of competition and BAI was .21.4. Construct Validity: The internal consistency coefficients among subscales ranging from .18 to .74. The correlation among various subscales with scale ranging from .48 to .87.5. Norm: The percentile norm was developed, which can provide the physical education teachers and coaches a basis to judge a bowler''s attention ability. The discriminant analysis conducted to determined if the different levelsof bowlers differed on BAI score. The results showed significant differencesamong three groups. The correlation analysis was also conducted to determinethe extent to which subject''s BAI responses predicted their bowling performance.The results indicated that the BAI can predict bowling performance. The foregoing analysis indicated that the reliability and validity of thisinventory was rather good and was indeed an effective inventory in measuringthe bowling attention level.
