<body><![CDATA[<p>According to the advice given by health experts, all school-aged children in    Elementary School and High School must perform daily, at least, 60 minutes of    physical exercise ranging from moderate to more vigorous activities (World Health    Organization, 2012). Being so that, besides the health benefits that daily exercise    provides which are necessary for the healthy development of children, it also    has a positive effect on young people in a social plane and makes them adhere    to the practice of physical activities, which leads them to create active lifestyles    in their youth as well as in their adulthood (Bouchard, Blair, &amp; Haskell,    2007; Donnelly, Blair, Jakicic, Manor, Rankin, &amp; Smith, 2009).</p>     <p>Despite this, many studies show that in the last few years children in First    World countries have become less active physically and that young people have    adopted a sedentary nature which keeps on increasing daily (Corbin, Pangrazi,    &amp; Le-Masurier, 2004; Currie et al., 2008; O’Donovan, Blazevich, Boreham,    Cooper, Crank, Hameret, 2010), and Spain is no exception (Beltrán, Beltrán,    &amp; Valenciano, 2008). This lack of participation may be due to limited ability    in motor skills or inadequate motor competence (Ennis, 1996, 2003; Standage,    Duda, &amp; Ntoumanis, 2005).</p>     <p>In the same manner, a high number of other studies have shown that motivation,    understood as the &ldquo;intensity in behavior, persistence, the choice of different    possibilities in action and performance&rdquo; (Roberts, 1992:6) is a crucial factor    which lies behind the participation in sports and physical activities (Ntoumanis,    Pensgaard, Martin, &amp; Pipe, 2004; Gónzalez-Cutre, Sicilia, &amp; Moreno,    2008; Yli-Piipari, Watt, Jaakola, Liukkonen, &amp; Nurmi, 2009). Motivation    makes pupils participate in physical activities, get involved and helps them    succeed in the fulfillment of motor skills.</p>     <p>On the one hand, enjoyment represents a key factor which underlies motivation    and participation in Physical Education (Cox, Smith, &amp; Williams, 2008; Cox,    Hagger et al., 2009; Ullrich-French, 2010). And, on the other hand, the understanding    of physical competence is connected to the proper realization of the motor skills    (Wallhead, &amp; Ntoumanis, 2004). Both factors are fundamental for individuals    to feel valued (Martens, 1996). From this, we can see the importance of the    role of the professor, whose influence is essential for students to improve    their motivation and perception of competence, which leads boys and girls to    improve their results in the practice of Physical Education (Sebastiani, 2010).</p>     <p>Perceived physical competition refers to the belief in the capacity that a    student has to excel in the development of a motor domain (Ferrer- Caja, &amp;    Weiss, 2000). Said competency is connected to the intrinsic motivation (Ommudsen,    2005), to the enjoyment (Biddle et al., 2003) and the level of participation    in physical and sportive activities (Fairclough, 2003). Recently enthusiasm,    excitement, and cognition have also been connected to the perception of competency    and the attitude towards the participation in physical education programs (Disham    et al., 2005; Hashim, Grove, &amp; Whipp, 2008). People who perceive themselves    as competent are more intrinsically motivated to pursue higher goals and are    more persistent during their participation (Harter, 1985). This is the reason    why perceived competency seems to have a more significant influence on intrinsic    motivation and is a decisive factor in children’s participation in physical    and sportive activities (Papaioannou, 1997). From there we can see that encouraging    feelings of competition in Physical Education in children will help them reach    higher goals in Physical Education (NASPE, 2004).</p>     <p>Rudisill et al. (1993) acknowledged that between the ages of 9 and 11 we could    reach a precise evaluation of the perceived motor competency in boys and girls.    Different studies (Hagger, Biddle, &amp; Wang, 2005; Moreno, &amp; Cervelló,    2005, among others), show that boys have better perception than girls of their    competency in Physical Education. Solmon, Lee, Belcher, Harrison, &amp; Wells    (2003) argue that said competency is due to girls perception of Physical Education    as a more appropriately male activity, which consequently makes them prove to    be less competent and derives in them avoiding any sort of connection to these    physical activities.</p>     <p>It also seems that previous negative experiences, in the practice of physical    activities, make people consider themselves as less competent (Gutiérrez, 2000).    In the same manner, pupils who feel respected and valued as equals tend to exhibit    more positive emotions connected to their self-esteem and performance (Duncan,    1993). To sum up, the positive opinion of the group helps the development of    the individual’s self-esteem.</p>     <p>On the other hand, pupils who receive positive feedback, fewer punishments    or critical comments, knowing that their teachers are aware of their performance,    tend to obtain more positive results along with higher levels of perceived competence    (Nicaire, Cogérino, Bois, &amp; Amorose, 2006). Now, it is clear that the teachers’    positive feedback is not the same for boys as for girls (Dunbar, &amp; O’Sullivan,    1986). In general, male pupils receive more attention from their teachers than    female pupils do (Duffy, Warren, &amp; Walsh, 2001). In addition, the type of    attention which boys receive varies. Drudy and UiChathian (2002) prove that    boys are acknowledged and accepted a lot more, along with being asked more questions    by their teachers’, in comparison to girls. Harter (1985) points out that perceived    competence rises from children’s social experiences in which the support and    feedback they receive be it positive or negative, from their peers and teachers    are internalized to form part of their perception of competence and motivational    orientation.</p>     <p>The circumstances in which the perception of competence is developed certainly    determine pupils’ judgment when it comes to their ability to reach high levels    of performance in physical activities (Moreno, &amp; Vera, 2008). This is why    previous experiences, along with the role of the teachers and peers, have an    important influence on the participation and persistence of pupils in the activities.    Effectively, more than two decades ago, Carreiro et al. (1988) made evident    the close relationship between the planning performed by Physical Education    teachers, the conduct of said teachers in the classroom and the students’ motivation    in the framework of Physical Education. Wilson, Williams, Evans, Mixon, &amp;    Rheaume (2005) also agree that children should participate in the design of    any form of intervention, as well as asking for responsibility between classmates    (Hastie, &amp; Siedentop, 2006). To this effect, it is necessary to be aware    of the different variables which affect the perception of competence in order    to have an impact on them. It is essential to employ valid and trustworthy instruments    to measure said variables as well as the population being analyzed. Given the    inexistence of instruments to evaluate the perception of competence in the field    of learning Physical Education, the validation of a new instrument in Spanish    is necessary to solve these limitations.</p>     <p>Starting with this approach, the goal of this study was to achieve the cultural    and linguistic adaptation to the two instruments developed by Scrabis-Fletcher    and Silverman (2010), as well as validate the Spanish educational context, especially    of boys and girls in the 6th grade.</p>     ]]></body>
<body><![CDATA[<p><b>Method</b></p>     <p><b>Participants</b></p>     <p>Trained research assistants administered questionnaires in randomly-selected    Spanish schools of Albacete. Twenty-seven schools of Albacete were invited to    participate in the study. An official invitation letter was sent to the 27 schools    randomly-selected for the research and all of them agreed to take part in the    study. Also, all children invited agreed to take part in the study. A total    of 780 children (approximately 4% from each school), of 6th grade of Elementary    school, aged 10-13 years old participated in the study (389 boys and 391 girls,    average age= 11.08 and SD =.43).</p>     <p><b>Measures</b></p>     <p>The instrument developed by Scrabis-Fletcher and Silverman (2010) has been    used to calculate the perception of competence (POC). This instrument was verified    in a study made on a sample of 1.281 students (627 boys and 654 girls) from    urban and suburban public schools on the east coast of the United States ranging    from ages 11 to 15 (average = 12.5, sd =.95).</p>     <p>Said instrument presents two patterns of 7 to 15 items respectively, grouped    according to 3 factors: personal experience, classmates and the teacher, with    8, 3 and 4 items in each factor. Within the aspect of the personal experience,    we find items related to feelings perceived by the student when it comes to    failure, personal ability, and taste. In the classmate aspect, we find items    related to social relations with other classmates, and finally, in the teacher    aspect, we find items which show the way students see their teachers’ actions.    In <a href="#t1">Table 1</a> we can see the items, divided by factors, which    form part of the questionnaire. As the study performed by Scarbis-Fletcher and    Silverman, the first pattern (M2F) only includes the classmates and teacher    factors, meanwhile in the second pattern (M3F) all three factors are included.    Each item has been evaluated following a 5-point Likert scale (1-In complete    disagreement, 5-In complete agreement). In our study, we included a third pattern    (M3FM), a modified version of the second pattern which better adjusts itself    to the reality of 11-year-old Elementary School students in Albacete (Spain).</p>     <p>&nbsp;</p>     <p align="center"><a name="t1"></a><img src="/img/revistas/mot/v14n4/14n4a02t1.jpg"/></p>     
<p>&nbsp;</p>     <p><b>Procedures</b></p>     ]]></body>
<body><![CDATA[<p>A literal translation of the article was carried out which included the questionnaire    (Scrabis- Fletcher and Silverman, 2010). Consequently, the translation of the    instrument was verified by a jury of experts made up of four university professors    of Expression and Body Language Didactics and the validation of this instrument    was carried out through a confirmatory factorial analysis.</p>     <p>For the quantitative study, a random selection was performed of 27 Elementary    school education centers in the province of Albacete (Spain). In order to collect    the information, all teachers in each center were asked for consent to collaborate    in this study. The handing out of the questionnaire was done collectively in    each classroom.</p>     <p>The study previously received the approval from the part of the parents, along    with permission from the education centers and the consent of the Physical Education    teachers, who were all informed through a letter of agreement of the different    objectives of the study. In order to make sure that each participant received    the same amount of information, a performance protocol was created in which    the different timetables were pointed out along with the information that was    to be given at every moment. In December of 2012, the instrument was completed    in the Physical Education classroom, and it was done in the presence of a researcher    who informed the students and teacher of the goal of this study. Upon handing    out the questionnaire to the students, they were asked to first of all pay close    attention to the instructions, which pointed out what they had to do, in order    to solve any doubts they may have. Utmost discretion was used at every moment,    assuring the participants of their anonymity in their participation in the study.    They were asked to avoid putting their names on the questionnaire; in the event    of this happening the questionnaire would be discarded. The completion of both    instruments was carried out in a single period of around 15 minutes.</p>     <p><b>Statistical analysis</b></p>     <p>Different R-programmed version 2.15.2 (2012-10-26) language packages have been    used (R Project, 2012). Initially, an exploratory analysis was carried out of    the different items with the help of statistics and graphs. Next, a study of    the internal consistency was carried out through the Cronbach alfa, using the    multilevel package version 2.5 (Bliese, 2012). Finally, the structuring of the    studied constructs was carried out through a confirmatory factorial analysis    (AFC). For this, the Lavaan version 0.5-11 package was used (Rosseel, 2012).    For the normality tests, packages stats 2.15.2, nortest 1.0-2 and psych 1.2.12    were used.</p>     <p>To evaluate all three models, confirmatory data analysis was carried out. Given    the categorical nature of the data and the lack of normality in the multivariant    distribution, confirmatory data analysis was chosen using a consistent estimator,    with the minimum squares analyzed (WLSMW - diagonally least squares with robust    standard errors and a mean-and- variance-adjusted test statistic).</p>     <p><b>Results</b></p>     <p>The In the exploratory analysis of the items, the normality of all items was    rejected with the Shapiro-Wilk tests (p-value&lt;2.2e-16 for all items) and    the Lilliefors test (p-value&lt;2.2e-16 for all items). In the joint study,    the Mardia test had elevated results in asymmetry 2537.5 as well as in the kurtosis    18.93 which is why the multivariant distribution that is formed cannot be considered    normal.</p>     <p>The internal consistency of the factors was calculated with the Cronbach IQ    alfa (Cronbach, 1951). In personal experience, a score of 0.67 was obtained,    0.42 in the classmates’ factor and 0.45 in the teacher factor. Despite not being    internally consistent on an individual level, all the charges are internally    consistent as a whole (alfa: 0.74).</p>     <p>Given the categorical nature of the data and the lack of normality in the multivariant    distribution, a confirmatory analysis of the data was chosen using a consistent    estimator of minimum squares analyzed (WLSMV).</p>     ]]></body>
<body><![CDATA[<p>The factorial charges are presented in <a href="#t2">Table 2</a> along with    the main statistics of the different items.</p>     <p>&nbsp;</p>     <p align="center"><a name="t2"></a><img src="/img/revistas/mot/v14n4/14n4a02t2.jpg"/></p>     
<p>&nbsp;</p>     <p>The factorial charges of the two-factor model (M2F) are all significant statistically    (p&lt;0.001), whereas the ones pertaining to the 3-factor model (M3F) are significant    statistically (p&lt;0.001) with the exception of item 7 which does not contribute    anything to this model, which is why we will create a new model with the elimination    of item 7 (M3FM), in this model all items are statistically significant. We    will develop the incentive for this process in the discussion.</p>     <p>We can appreciate a strong correlation between the latent variables in the    3 models since all are positive and very significant (p&lt;0.001) as shown in    <a href="#t3">table 3</a>.</p>     <p>&nbsp;</p>     <p align="center"><a name="t3"></a><img src="/img/revistas/mot/v14n4/14n4a02t3.jpg"/></p>     
<p>&nbsp;</p>     <p>Due to the size of the sample, it is not convenient to use the Chi-Square &#967;²    test since it is sensitive to the size of the sample. Therefore, it is advisable    to use other indexes which are more reliable for testing large samples. Due    to this, as Bentler advises (1995), a combination of indexes, such as the ones    used by Scrabis- Fletcher and Silverman (2010) have been taken into consideration    to be able to demonstrate the results. The indexes recommended by Jackson, Gillaspy    and Purc-Stephenson (2009) and Byrne (2008) have been included, representing:    &#967;², &#967;²/g.1., GFI (Goodness of fit index), AGFI (Adjusted Goodness    of fit index), SRMR (Standardized Root Mean Square Residual), RMSEA (Root Mean    Square of Approximation), TLI (Tucker Lewis Index), CFI (Comparative Fit Index)    and IFI (Incremental Fit Index). In <a href="#t4">table 4</a> we can see the    global results acquired from the first analysis upon applying the different    adjustments to the models (the measurements y2, RMSEA, TLI, CFI and IFI shown    in <a href="#t4">table 4</a> are consistent).</p>     ]]></body>

<p>&nbsp;</p>     <p>The confidence measurements at 90% in RMSEA are (0.083, 0.116) in model M2F,    (0.069,0.082) in model M3F and (0,067,0,081) in model M3FM.</p>     <p>With the goal of improving this adjustment, an analysis of the correlations    between the residual items was done, verifying that the residual items 3 and    11 (classmates opinion, within the Classmate aspect) and 4 and 8 (teachers orders,    within the Teacher aspect) were very correlated, besides in the 2-factor model    the errors in items 3 and 15 (classmates opinion, within the Classmate aspect)    were very correlated. All three models improved upon inserting said corrections    to the levels of adjustment, the levels of adjustment are shown in <a href="#t5">table    5</a> (the measurements of &#967;², RMSEA, TLI, CFI, and IFI showed in <a href="#t5">table    5</a> are consistent).</p>     <p>&nbsp;</p>     <p align="center"><a name="t5"></a><img src="/img/revistas/mot/v14n4/14n4a02t5.jpg"/></p>     
<p>&nbsp;</p>     <p>The confidence measurements at 90% in RMSEA are (0.066,0.101) in model M2F,    (0.059,0.073) in model M3F and (0.055, 0.070) in model M3FM.</p>     <p>A gender study has been carried out to figure out if there are significant    differences in the different items of the questionnaire. In order to do this    a level of significance has been established &#945;=0.05 and Bonferroni’s corrections    have been taken into account to make multiple contrasts. The results of the    descriptive statistics and the p- value of the Chi contrast are shown in <a href="#t6">Table    6</a>; this contrast proves that significant differences do not exist in any    items between the boys and girls from our study.</p>     ]]></body>

<p>&nbsp;</p>     <p><b>Discussion</b></p>     <p>In relation to the different factors in the instrument, Personal Experience,    Classmates and Teacher, theory shows that all three factors are fundamental    in the development of Physical Education by the students (Scrabis-Fletcher,    &amp; Silverman, 2010). In our study we have verified this fact, proving that    the perception of competence in Physical Education is strongly influenced by    the classmates (correlation of 0.980), followed by that of the teacher (correlation    of .958) and finally by personal experience (correlation of 0.879). The three    factors also show positive and elevated correlations between each other, proving    that the three factors are important and positive, but when joined together    their influence is intensified. To this effect, it is important to establish    joint performances with the goal of improving the competence of students in    Physical Education. Specifically, the strongest correlation is that between    the factors Classmates and Teacher, given that both occur in the same environment.</p>     <p>Due to all the above, it is fundamental that classmates and the personal experience    of the student be taken into account in the planning and development of motor    tasks in Physical Education, geared to 6th-grade Elementary school students    (Contreras, &amp; Gil, 2010).</p>     <p>When it comes to the items in the questionnaire, the ones that are most influenced    by the Perception of Competence are numbers 5, 9 and 14 in the Personal Experience    factor, number 15 in the Classmate factor and numbers 4 and 10 in the Teacher    factor. Their knowledge is fundamental, as by promoting an interest in these    activities along with feelings of competence, this will help the student reach    the goal of this subject since according to Bandura’s theory on social cognitivism    (1986), it is necessary to recognize:</p>     <p>1. The interactive effect of students’ feelings and thoughts (previous experience,    attitudes, the importance of the subject).</p>     <p>2. Environmental factors (context, teacher, classmates).</p>     <p>3. Performance (level of commitment, dedication to study).</p>     ]]></body>
<body><![CDATA[<p>We must point out that the consistency among the different items from the instrument    is high as a whole (Cronbach’s alfa: 0.74), despite the low consistency of the    items of each factor, having 0.67 for personal experience, 0.42 in the classmate    factor and 0.45 in the teacher factor.</p>     <p>There is a high correlation between all items, including those in different    factors, due to the inter-correlation between all three factors. Item 7 stands    out because of the irrelevant information it provides; this is not the case    in the original study. This lack of information given in item 7 (I think I can    do well the activities that I perform away from school) describes perfectly    the current social context among 11-year-olds in Spain. Arguments such as &ldquo;lack    of time&rdquo; and &ldquo;homework&rdquo; make that around 70% of students do not do regular physical    activities in their free time, this is especially the case for girls (Román,    Serra, Ribas, Pérez-Rodrigo, &amp; Aranceta, 2006 and Granda, Montilla, Barbero,    Mingorance, &amp; Alemany, 2010). Like Papaioannou (1997) points out, children    without previous experiences in physical and sports activities in their free    time have lower perceived competence when it comes to participating in Physical    Education school programs. Because of this, we think the Spanish version of    this model should not include item number 7 due to the lack of using it has    in reaching the goal of calculating the perception of competence of students.</p>     <p>It is convenient to point out that items 12 and 14 have a high correlation    with item 10. After a detailed study of the questions, this connection may be    due to the circumstances of the questionnaire (Bollen 1989), in this case to    the double negative of the question.</p>     <p>If we compare the adjustment of the different models with the data obtained    from Scrabis- Fletcher and Silverman’s (2010) original study, in this study    the questionnaire is validated by associating models M2F and M3F with the following    results: the 2-factor model (AGI=0.98, AGFI=0.97, SRMR=0.03, and RMSEA=0.05)    is a lot better adjusted than the 3-factor model (AGI=.90, AGFI=.86, SRMR=0.07,    and RMSEA=0.09), in the present study both models prove to be very similar.    Comparing both studies, the 2-factor model of the present study presents a worse    adjustment than that of the original study (AGI=0.999, AGFI=0.995, SRMR=0.044    and RMSEA=0.081, confidence interval RMSEA 0.063-0.101), but the 3-factor model    is better adjusted (AGI=0.996, AGFI=0.993, SRMR=0.058 and RMSEA=0.066, confidence    interval RMSEA 0.059-0.073) than in the original study, having this study verify    the construct presented in the field of the current study. But we can see that    by eliminating item 7 we get a better adjustment (AGI=0.996, AGFI=0.994, SRMR=0.052    and RMSEA=0.062, the confidence interval RMSEA 0.055-0.070). The three models    present an adequate global adjustment proven by Hu &amp; Bentler (1999).</p>     <p>The main limitations of this study were that the sample came from only one    region of Spain (Albacete) and the sample was composed only by children of the    sixth year of Primary Education. Therefore, future research should study children    of other Spanish regions and with different ages.</p>     <p><b>Conclusion</b></p>     <p>Game This study allows Physical Education teachers the possibility of comparing    the results when the validated tool is used with the end goal of finding deficiencies    in any of the factors or items included in the instrument.</p>     <p>Since this study was carried out exclusively on children in 6th grade Elementary    School in the province of Albacete (Spain), and given that there are no great    differences in the school curriculum of Physical Education in the third cycle    of Elementary School between autonomous communities in the Spanish education    system, said instrument can be used on a national level. Other provinces can    carry out similar studies, in other levels of the Spanish education system,    with the goal of proving the results shown here. And through this establish    a joint timetable between the teachers of all levels and use a tracking construct    which would allow the correction of any deficiencies which are detected and    have an impact on them in the best way possible which will allow the improvement    of the teaching of Physical Education within the education systems. The construct    has also been proven to be equally valid for boys as for girls, not showing    any significant differences in any of the items.</p>     <p>We can conclude the verification of the Perception of Competence in Middle    School Physical Education instrument in a Spanish social context, specifically    6th grade Elementary School students in the province of Albacete, as well as    that of the 2-factor and 3-factor constructs, with the exception of item 7,    to be used to determine the perception of competence in Elementary School 6th    graders. The first, includes the factors teacher and classmates, which can be    used to determine the programming of the subject of Physical Education, leaving    out the 3-factor questionnaire which besides the Personal Experience factor,    also includes to establish the details (intensity, difficulty, etc&hellip;) of motor    tasks to realize the function of the personal experiences of students.</p>     <p>&nbsp;</p>     ]]></body>
