The behavioral regulation in sport questionnaire (BRSQ): instrument development and initial validity evidence 总被引:1,自引:0,他引:1
The purpose of the four studies described in this article was to develop and test a new measure of competitive sport participants' intrinsic motivation, extrinsic motivation, and amotivation (self-determination theory; Deci & Ryan, 1985). The items for the new measure, named the Behavioral Regulation in Sport Questionnaire (BRSQ), were constructed using interviews, expert review, and pilot testing. Analyses supported the internal consistency, test-retest reliability, and factorial validity of the BRSQ scores. Nomological validity evidence was also supportive, as BRSQ subscale scores were correlated in the expected pattern with scores derived from measures of motivational consequences. When directly compared with scores derived from the Sport Motivation Scale (SMS; Pelletier, Fortier, Vallerand, Tuson, & Blais, 1995) and a revised version of that questionnaire (SMS-6; Mallett, Kawabata, Newcombe, Otero-Forero, & Jackson, 2007), BRSQ scores demonstrated equal or superior reliability and factorial validity as well as better nomological validity. 相似文献

Researchers in the fields of cognitive psychology and education have been studying the negative effects of noise on human performance for almost a century. A new empirical study that builds upon past relevant research on (1) test accommodations and (2) auditory distraction and academic performance was conducted with elementary age students. Reading comprehension tasks were completed by students with and without learning disabilities while wearing and not wearing noise‐reducing headphones. Results of three independent statistical analyses are presented. Implications, limitations, and the need for future research are also discussed. 相似文献

We examined the plasma concentration curve obtained over 6 h after the ingestion of 2 g of creatine (Cr) (equivalent to 2.3 g Cr x H2O) contained in meat or in solution in five non-users of creatine supplements. Peak plasma creatine concentration was lower after the ingestion of meat but was maintained close to this for a longer period. Measurements of the area under the plasma concentration curve indicated approximate bioequivalence of creatine contained in meat with the same dose supplied in a solution. In a separate study, we examined the plasma concentration time curve after ingestion of solid Cr x H2O. Creatine ingested as a lozenge (crushed in the mouth and swallowed) or as a crystalline suspension in ice cold water resulted in a 20% lower peak concentration and 30-35% smaller area under the plasma creatine concentration curve than the same dose administered in solution. Despite a possibly lower bioavailability, 2.3 g Cr x H2O supplied in either solid form was nonetheless sufficient to raise the plasma concentration five- to six-fold in individuals with a mean body mass of 75.6 kg. We conclude that creatine administered as meat or in solid form is readily absorbed but may result in slightly lower peak concentrations than when the same dose is ingested as a solution. 相似文献

There are two kinds of scientific writing: that which is intended to be read, and that which is intended merely to be cited. The latter tends to be infected with infectious verbal pomposity (IVP). The disease is ubiquitous, but often undiagnozed, with the result that infection spreads to writing of the first type. This paper summarizes our knowledge of the condition, presents a few clinical cases, and offers a new approach to its control. 相似文献
