Considerations Related to the Definition, Measurement and Analysis of Perceived Motor Competence

Psychometric evaluation of the pictorial scale of perceived movement skill competence in Chinese children: An item response theory analysis

AIM

This study aimed to investigate the psychometric characteristics of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) in Chinese children, utilizing the principles of item response theory (IRT).

METHODS

A total of 284 children (147 boys), aged 4-10 years (Mage = 7.39, SD = 2.18), from four schools were recruited for testing, adhering to the principle of random sampling. The Rasch model was applied to evaluate the rating scale validity, local independence, scale dimensionality, person and item fit statistics, and differential item functioning (DIF).

RESULTS

(1) The rating scale validity was confirmed by the monotonically increasing trend in both average item difficulty measures and Andrich thresholds. (2) However, the observation that standardized residual correlations for all items remained below 0.3 unequivocally confirmed the presence of local independence among the variables. (3) The scale's dimensions were substantiated, with Rasch measures explaining 40.6% of total variance, exceeding the 40% threshold. Additionally, the first contrast had an eigenvalue of 1.8 and explained 8.80% of the variance, both exceeding the minimum 3:1 ratio. Consequently, the unidimensionality assumption of the item was supported. (4) Person and item fit statistics indicated requisite reliability and separation, with all achieving suitable infit and outfit measures, and point-biserial correlations exceeding 0.55. (5) Regarding gender DIF, it was observed that the majority of items did not exhibit statistically significant gender DIF effects (p > 0.05) except item 8 (Bounce a ball, t = -2.74, p < 0.01, DIF = -0.51).

CONCLUSION

Rasch analysis revealed that the instrument exhibited strong scale validity among Chinese children, adhering to the Rasch model's unidimensionality and local independence principles, with robust person and item reliability and separation. All items demonstrated a good fit. Additionally, the significant gender difference in item 8 (Bounce a ball) warrants further consideration. In conclusion, PMSC is suitable for assessing the PMSC of Chinese children.

Perceived physical literacy in children and early adolescents: Two valid and reliable versions of the PL-C Quest

Perceived physical literacy contributes to the understanding of individuals' physical activity (PA) engagement. It is important a scale is validated in the population of interest. Also, the type of administration may affect reliability and validity. So, the aim of this study was twofold: 1) to examine evidence of validity and reliability of the Spanish version of the Physical Literacy for Children Questionnaire (PL-C Quest) in a cohort of children and adolescents and 2) to assess two versions of administering the scale. The study was conducted in two stages, depending on the administration format of the PL-C Quest (double-dichotomous, and four-point response style) in a cohort of 2004 (n1 = 916; n2 = 1088) students. In both administration forms, evidence of validity (relation with other variables, i.e., concurrent and predictive, and structural validity), invariance (between boys and girls) and reliability (test-retest and internal consistency) were examined. There was evidence of validity for both administration types, with adequate reliability and good to excellent test-retest reliability for both administration forms. Both methods of administration for the PL-C Quest can capture perceived physical literacy in Spanish 8- to 14-year-old children and early adolescents.

Psychometric Properties of the Pictorial Scale of Perceived Movement Skill Competence for Young Norwegian Children

The objective of this study was to examine the psychometric properties of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) for young Norwegian children, a scale that is aligned with skills assessed in the Test of Gross Motor Development- Third Edition. We used convenience sampling to recruit 396 Norwegian-speaking children (7-10-year-olds) who completed the PMSC. A confirmatory factor analysis (CFA) confirmed factorial validity for the proposed three-factor model of the PMSC, encompassing measures of self-perceived ball, locomotor, and active play competence. Internal item consistency coefficients of these sub-scales were acceptable, and subsequent measurement invariant analysis found a gender difference such that boys rated their competence higher than girls in running, jumping forward, hitting a ball (racket), kicking, throwing a ball and rope climbing, while girls rated themselves higher, compared to boys, in galloping and skating/blading. Furthermore, there was a slightly better model fit for boys than for girls. Several items were significantly related to children's age, and the three-factor model exhibited differential age related factor mean differences across older and younger children. Overall, we found the PMSC to have acceptable psychometric properties for confident use in assessing perceived motor competence among 7-10-year-old Norwegian children, though we observed age and gender differences in children's responses that warrant careful interpretation of results and further research investigation.

The "thinking system" in a new school concept: A rhythmic teaching approach in physical education to develop creativity

System Thinking is an actual construct supported by several scientific evidence that offer a perspective on how phenomena relate. Rhythm methodology, teaching-learning, and enjoyment in physical education are the main system elements we hypothesize interacting closely to determine direct or mediated effects on motor creativity and rhythmic perceptive capacity. Seventy-six elementary and middle school students (8.9 ± 2.1 years) were randomly assigned to two groups: a) an intervention group that received a physical education lesson based on rhythmic methodology and b) a control group that received conventional lessons without specific rhythmic interventions. Participants were engaged in eight physical education lessons lasting one hour each for eight weeks. Tests and questionnaires were administered before and after the intervention to evaluate motor creativity, rhythmic perception capacity, self-perception and enjoyment. Two lessons were randomly analyzed to identify the teaching style and motor content (moderate and vigorous activity). The main results revealed direct effects on the intervention group's motor creativity (p = 0.001) and its rhythmic perception capacity (p = 0.02). Furthermore, enjoyment mediated the effects of the intervention on motor creativity (p = 0.01). Finally, the results have shown that self-perception does not mediate the effect of rhythmic intervention group on motor creativity and rhythmic perceptive capacity (p > 0.05). A rhythmic methodology proposed by specific multi-teaching styles can involve children and young people in an enjoyable activity with more moderate to vigorous physical activity.

Development and validation of a test instrument for the assessment of perceived basic motor competencies in first and second graders: the SEMOK-1-2 instrument

Both actual motor competencies (AMC) and perceived motor competencies (PMC) play an important role in motor development research and children's physical and psychological development. PMC refer to children's perceptions of their motor competencies. To assess the PMC of first and second grade children (aged 6-9 years), the SEMOK-1-2 instrument was developed. The instrument is aligned to the validated MOBAK-1-2 instrument which assesses AMC in the competence areas "object movement" and "self-movement" Accounting for possible reading difficulties in younger children, the motor tasks and answer options were illustrated and explained verbally. The purpose of this study was to test and validate the SEMOK-1-2 instrument and investigate the associations between the constructs AMC, PMC and physical activity (PA), whereby PA was measured by the participation in team and individual sports. Data from N = 404 pupils in the German-speaking part of Switzerland from first and second grades (M = 7.8 years, SD = 0.69, 49% boys) were analyzed. Confirmatory factor analyses were conducted to test the factorial validity of the SEMOK-1-2 instrument. Structural equation models were used to investigate the association between the constructs. The analyses confirmed a two-factor structure with the factors PMC "object movement" and PMC "self-movement", corresponding to the factors existing in the MOBAK-1-2 instrument. Latent correlations between AMC factors and the corresponding PMC factors were r = 0.79 for "object movement" and r = 0.76 for "self-movement". Associations with external criteria and covariates, such as sex, were associated with both AMC and PMC. Analyses also revealed that children who participated more often in individual and team sports showed higher levels in both AMC and PMC. The confirmation of the two-factorial structure of the SEMOK-1-2 instrument and the associations between AMC and PMC as well as external criteria indicate construct and criterion validity. The SEMOK-1-2 instrument can be economically utilized for assessing PMC and is also suitable for the monitoring of PMC in the context of Physical Education.

Basic motor competencies in Slovak children from the 3rd and 4th grade elementary age group

Background

The development of movement skills is the basic goal of physical and sports education. Their level is a determining factor in the subsequent involvement of the child in physical activities. Goal is to contribute to the knowledge of basic motor competencies (BMC) in the 3rd and 4th grade boys and girls from elementary schools.

Methods

We collected data from 468 children (Mage = 9.6, SD = 0.6 years; 228 girls and 240 boys) from 16 third grade and 16 fourth grade classes at ten elementary schools in different parts (central, west, north) of the Slovak Republic. The primary data on the basic motor competencies of the examined groups were obtained by means of the MOBAK-3 test battery. Construct validity was analyzed by confirmatory factorial analysis and relationships between BMC and age, gender and BMI were analyzed by structural equation modeling.

Results

Boys had a better performance in object movement activities than the girls p < 0.01. Situation in self-movement activities was different, girls had a better performance than boys p < 0.05. The general expectation that grade is a factor to improve the performance in basic motor competencies in the compared 3rd- and 4th-graders was not clearly fulfilled. This assumption was only confirmed in girls (object movement p < 0.05, self movement p < 0.01). Confirmatory factor analysis confirmed the two-factor structure of basic motor competencies on object-movement and self-movement, while gender, BMI and age were confirmed as significant covariances.

Conclusions

The theory of BMC in the 3rd- and 4th-graders at elementary schools is an appropriate method to uncover the grounds for a positive attitude to physical activities later in life.

Psychometric properties of the Adolescent Motor Competence Questionnaire for Norwegian adolescents

The objective of this study was to examine the psychometric properties of the Adolescent Motor Competence Questionnaire (AMCQ) for Norwegian adolescents. To this end, a sample of 349 Norwegian-speaking adolescents (13-16 years old) were recruited and completed the AMCQ. Initial results showed that confirmatory factor analysis (CFA) did not indicate statistical support for previous statistical models reported in the literature. Further analysis indicated factorial validity for a novel three-factor model identified through exploratory factor analysis, encompassing measures of fine motor skill (α = 0.65), gross motor skill (α = 0.74), and activities of daily living (ADL; α = 0.79) with acceptable internal consistency coefficients. Subsequent analysis indicated indices of measurement invariance in the study sample, as males rated their competence higher compared to females in 19 of the 27 items, and better model fit was obtained for the female adolescents. Strong invariance was tenable, and no factor mean differences were found across older and younger adolescents or across BMI scores. Overall results thus suggested that the AMCQ has acceptable psychometric properties and can be confidently used in further work with perceived motor competence in Norwegian 13-16 years-old adolescents.

Configurations of actual and perceived motor competence among elementary school children in China: differences in physical activity

Background

Actual motor competence (AMC) and perceived motor competence (PMC), as determinants of children's active participation in physical activity (PA), were important for children's healthy development. The correlation between the two had been confirmed. To further understand this relationship, this study investigated the current status of AMC, PMC, and PA in Chinese school-age children, used a person-centered approach to reveal the characteristics of the development of motor competence (MC) in Chinese school-age children and the differences in the level of PA among different MC profiles of children.

Materials and methods

A total of 532 children (age: M = 9.37, SD = 1.80 years-old) from grades 1 to 6 participated in this cross-sectional study (male, n = 284, 53.4%; female, n = 248, 46.6%). The Test of Gross Motor Development-3 (TGMD-3) was used to measure children's AMC, the Pictorial Scale of Perceived Movement Skill Competence (PMSC) to measure children's PMC, and the revised Chinese version of Physical Activity Questionnaire for Older Children (PAQ-C) to assess children's PA levels.

Results

There were some gender differences in AMC but no significant gender differences in PMC and PA in children. AMC and PA levels increased as the children aged, while PMC showed some decline. Cluster analysis identified four groups of children with different MC profiles. Two groups of children had corresponding AMC and PMC levels (the "high-high" cluster, N = 200, 38.91%; the "low-low" cluster, N = 63, 12.26%), and the other two groups were inconsistent in AMC and PMC (the "high-low" cluster, N = 100, 19.46%; the "low-high" cluster, N = 151, 29.38%). Significant differences in PA levels were found between children with different MC profiles. The "high-high" cluster children had the highest PA levels, whereas the "low-low" cluster children demonstrated the lowest PA levels.

Conclusion

AMC, PMC, and PA in Chinese school-age children were consistent with the pattern of child growth and development. Children with high AMC and high PMC usually had high levels of PA. Therefore, it was recommended to seize the best opportunity to intervene with children, and family, school, and community should synergize to help children improve AMC and PMC, and then actively participate in PA.

Associations Between Motor Competence and Physical Activity, Physical Fitness and Psychosocial Characteristics in Adolescents: A Systematic Review and Meta-analysis

BACKGROUND

Motor competence is an integral component of the health and performance of youth. Numerous studies support the hypothesis that motor competence interacts with perceived motor competence and physical fitness during childhood to induce positive (e.g. healthy weight status) or negative (e.g. reduced physical activity engagement) trajectories. Yet, while adolescence is a key period of rapid growth and maturation, no systematic reviews and meta-analyses have examined the association between motor competence and physical activity, physical fitness and psychosocial characteristics solely within adolescents.

OBJECTIVES

This study aimed to (1) analyse the scientific literature evaluating associations between motor competence and physical activity, physical fitness and/or psychosocial characteristics amongst adolescents; (2) evaluate the associations between motor competence and physical activity, physical fitness characteristics and/or psychosocial characteristics amongst adolescents; and (3) investigate the impact of moderator variables (i.e., age, sex, type of motor competence assessment) on the associations.

METHODS

A systematic search of electronic databases was conducted, followed by a qualitative synthesis of study methods. Random-effects meta-analyses were performed to establish the magnitude and orientation of pooled correlation coefficients between motor competence and physical activity, physical fitness and psychosocial characteristics of adolescents, whilst considering potential moderators (i.e., age, sex, type of motor competence assessment).

RESULTS

Sixty-one studies were included, totalling 22,256 adolescents. Twenty-seven different assessments of motor competence were used, with 31 studies utilising product-orientated (i.e. outcome) motor competence assessments. Meta-analyses of 43 studies showed that motor competence was positively associated with physical activity (r = 0.20 to 0.26), some physical fitness characteristics (e.g. muscular strength, cardiovascular endurance; r = 0.03 to 0.60) and psychosocial characteristics (r = 0.07 to 0.34), and inversely associated with weight status (r =  - 0.36 to - 0.10), speed (r =  - 0.31) and agility (r =  - 0.37 to 0.41). Associations with flexibility were unclear.

CONCLUSIONS

The results of this systematic review and meta-analysis support the hypothesised interactions of motor competence with physical activity (positive), physical fitness (positive except for weight status, speed and agility) and psychosocial characteristics (positive) in adolescence. However, methodological approaches vary considerably (e.g. variety of motor competence assessments utilised), with limitations of the current literature including an inadequate assessment of motor competence, a lack of longitudinal observations and a failure to account for biological maturation. Future research assessing associations between motor competence and physical activity, physical fitness and psychosocial characteristics of adolescents should include longitudinal observations of a combined motor competence assessment (i.e. process and product) and account for biological maturation. Improved evaluation using these recommendations could provide more accurate data, leading to more targeted interventions to improve adolescents' physical and psychosocial outcomes.

Perceived motor competence in early childhood predicts perceived and actual motor competence in middle childhood

The study aims were to (1) identify perceived motor competence (PMC) and actual motor competence (AMC) profiles in children at two time points (early and middle childhood) 3 years apart, (2) explore transitions between the profiles from T1 to T2, and (3) investigate how PMC-AMC profiles at T1 differ in their mean values for AMC and PMC variables at T2. PMC was assessed by the pictorial scale of Perceived Movement Skill Competence for young children (PMSC). At T1, AMC was measured with Test of Gross Motor Development-third version (TGMD-3), and at T2, a shortened TGMD-3 was used. To identify the PMC-AMC profiles using latent profile analysis, the Mplus statistical package (version 8.7) was used. For aim 3, the Bolck-Croon-Hagenaars (BCH) method was used. There were 480 children (mean age 6.26 years, 51.9% boys) at T1, 647 children (mean age 8.76 years, 48.8% boys) at T2 (some children were too young to have the PMC assessment at T1), and 292 at both time points. For aim 1, three profiles were identified at each time point for each gender. Boys had two realistic profiles with medium and low levels of PMC-AMC, and an overestimation profile. Girls had a medium realistic profile, an overestimation, and an underestimation profile. The PMC-AMC profile in early childhood predicted the PMC-AMC profile (aim 2) and AMC and PMC variables (aim 3) in middle childhood, especially if a child had low PMC in early childhood. Children with low PMC in early childhood are at risk of low PMC and less AMC development in middle childhood.

"Profiles of motor competence and its perception accuracy among children: Association with physical fitness and body fat"

The main goals of this study were to identify profiles in school-aged children based on actual Motor Competence (MC) and accuracy of Perceived Motor Competence (PMC) and to examine how children with different profiles differ in terms of Physical Fitness (PF) and Body Fat percentage (BF%). The MC of a total of 287 children (51.6% boys, aged between 6 and 10 years-old) was assessed using the Motor Competence Assessment (MCA) instrument, and the accuracy of the PMC was measured using motor tasks (standing long jump, throwing, kicking, and walking backwards). PF and BF% were assessed using the 20m shuttle run test and TANITA, respectively. Cluster (C) analysis revealed four profiles, two of which were aligned - high MC-accurate PMC (C4) and low-inaccurate (C2), and two that were non-aligned - high-inaccurate (C1) and low-accurate (C3). Children in C4 performed better on PF and had less BF% than children in C3 and C2.

Child perceived motor competence as a moderator between physical activity parenting and child objectively measured physical activity

This longitudinal study aimed to examine how physical activity parenting (PAP) directly predicted objectively measured children's moderate-to-vigorous physical activity (MVPA) and sedentariness over a three-year transitional period from early to middle childhood, and second, whether the children's perception of motor competence (PMC) mediated or moderated the influence of PAP to children's MVPA or sedentariness. At time 1 (T1), PAP and children's (N = 396, mean age 5.80, SD 1.04) PA were assessed by parental questionnaire. Three years later, at time 2 (T2), children's (N = 396, mean age 8.80, SD 1.04) PMC was measured by a validated pictorial scale, and MVPA and sedentariness were measured by accelerometers. All the analyses were conducted using the Mplus statistical package (Version 8.4). The models were adjusted for the following covariates: children's PA (T1), gender (T1), age (T1), mean accelerometer measurement in hours per day (T2), and parents' education level (T1). Results showed that PAP at T1 did not significantly predict level of MVPA or sedentary time at T2 and, therefore, PMC did not mediate the PAP-children's MVPA or sedentary time relationship either. However, PMC significantly moderated the relationship between PAP and MVPA but not between PAP and sedentary time. The results suggested that parental support positively predicts children's MVPA among children with low PMC but not among children with high PMC. This unique finding proposes that family-based PA interventions could benefit from screening of children with low PMC and provision of PA counselling to their parents.

The mediational role of motivation in the model of motor development in childhood: A longitudinal study

The aim of this study was twofold: first, to examine the stability of the hypothesized conceptual model of motor development (without and with including various types of motivation) when children are followed up one-year later, and second to examine longitudinally whether changes in one model variable predict changes in other variables, according to the hypothesized pathways in the model. A sample of 361 Spanish students (50.7% girls, 8-11 years old) voluntarily participated in this study. In relation to the first aim, structural equation modeling revealed the expected positive relationship between the model variables in both measurement times. That is: actual motor competence (MC) predicted physical activity (PA) (p < .001), perceived MC mediated the relationship between actual MC and PA (p < .001), and autonomous motivation mediated the relationship between perceived MC and PA (p < .05). Moreover, the comparison of the invariance analysis showed non-practical differences between the unconstrained model and the constrained model, supporting the stability of the model over time. In relation to the second aim, the hypothesized model in Time 2 controlling for Time 1 values showed that changes in children's actual MC positively predicted changes in their perceived MC (p < .001), which in turn, predicted changes in their autonomous motivation (p < .001), and PA (p < .001) at Time 2. Based on these findings Physical Education teachers are recommended to foster children's actual and perceived MC as well as their autonomous motivation over time in order to promote PA strategies for lifelong health.

Actual and Perceived Motor Competence in Chilean Schoolchildren before and after COVID-19 Lockdowns: A Cohort Comparison

(1) Background: the measures applied in Chile to reduce COVID-19 infections have been very strict, mainly for children who have experienced lockdowns and school closures for almost two years. Emerging evidence indicates that lockdowns have had several negative effects on children; therefore, the present study seeks to analyze the secular effects of COVID-19 lockdowns on Chilean students’ actual motor competence (AMC) and perceived motor competence (PMC). (2) Methods: using a sequential cohort design, data from 523 fifth-grade students at nine elementary schools (46.8% girls, age M = 11.11, SD = 0.66) were assessed in 2018–19 (pre-lockdown) (n = 265) and 2022 (post-lockdown) (n = 258). (3) Results: in the domain of object control (AMC and PMC), no significant differences were found (AMC p = 0.559; PMC p = 0.682). In the self-movement domain of AMC and PMC, the significant differences found presented a small effect size (AMC p = 0.044, ηp2 = 0.01; PMC p = 0.001, ηp2 = 0.03). (4) Conclusions: although the differences encountered were not drastic, self-movement skills tended to be greatly affected by the lockdowns resulting from the COVID-19 pandemic. These findings broaden information on the negative consequences of the pandemic on students in aspects related to an active and healthy life.

Social Acceptance in Physical Education and the Regular Classroom: Perceived Motor Competency and Frequency and Type of Sports Participation

This study examined relations of primary school children’s perceived physical competence and sports participation (frequency and type) with social acceptance in the regular classroom and physical education (PE) and whether these relations differed depending on the type of sport children participated in (team vs. individual sports). In total, 182 children (48.9% boys, mean age 9.90 years, SD = 1.23) filled out questions on their perceived physical competence and sports participation and indicated three peers with whom they liked/disliked working in PE and the regular classroom. Multilevel structural equation models in Mplus showed that frequency of sports participation was positively related to social acceptance in the context of PE. Additionally, for children in team sports, the frequency of sports participation was related to their social acceptance in PE, whereas for children in individual sports, perceived physical competence was related to social acceptance in PE. No relations were found in the regular classroom. Relations of perceived physical competence and sports participation with social acceptance seem to depend on the school context and the type of sport involved. In designing PE classrooms, children’s physical competence and sports participation seem essential factors to take into account to provide all children with positive social experiences.

Validity evidence for the Pictorial Scale of Perceived Water Competence short form (PSPWC-4)

Promoting swimming and water safety is an important public health issue. The Pictorial Scale of Perceived Water Competence (PSPWC) requires children to indicate their perceived competence using three difficulty levels for 17 swimming scenarios. The aim was to purposefully select four critical scenarios of the PSPWC to create the PSPWC-short form and test for associations with actual swim competence. Four of 17 scenarios were selected and extended to a four-point response scale by adding an extra difficulty level. Parents whose children had participated in at least 1-week swim-intensive programme in 2021 were invited to participate in the study, and perceptions of 139 children (mean age 6.9 years, SD = 1.9) were matched with certificate data of actual swim competence pre- (n = 139) and post-programme (n = 29). Moderate positive correlations were found between swim level at programme start and perception of: retrieving an object in deep water (rho = 0.57), swimming on front (rho = 0.60), swimming on back (rho = 0.69), treading water (rho = 0.63) and the summed score of all four (rho = 0.71). After adjusting for sex and age, higher perceived skill was still significantly associated with increasing achieved skill levels. The PSPWC-short form appears to provide a valid measure to be used as a brief screening assessment.

Relationship between Perceived Physical Competence and Outdoor Play among Children Aged 9-12 Years-Focused Sex-Specific Differences

BACKGROUND

Outdoor play (OP), which is considered important for children's development, is declining every year. Perceived physical competence (PPC) is a vital factor that promotes physical activity such as OP, sports clubs, etc., but the relationship between PPC and OP was unknown. The purpose of this research was to investigate the relationship between PPC and OP in children and consider whether there were any sex-specific changes.

METHODS

A cross-sectional study was conducted in Japan with 288 children (134 girls, age: 10.6 ± 1.01 years). OP was assessed using an original self-report questionnaire. Each weekday, the children reported the time of OP and were classified as "high" if they played outside for at least an hour three times. PPC was evaluated with a self-report questionnaire developed by Okazawa et al. (1996). It has 12 questions and was assessed on a 5-point Likert scale. After adjusting for age, sex, BMI, screen time, sports club participation, and the number of friends, logistic regression analyses were carried out.

RESULTS

Children with better PPC were significantly more likely to be classified as "high" [crude odds ratio (OR): 1.04; 95% confidence interval (CI): 1.00-1.08; adjusted OR: 1.04; 95% CI: 1.00-1.08]. Only girls with better PPC were significantly more likely to be classified as "high" in a sex-based stratified analysis [crude OR: 1.08; 95% CI: 1.01-1.15, adjusted OR 1.09; 95% CI: 1.02-1.17].

CONCLUSIONS

Particularly among girls, OP could be promoted as a voluntary physical activity with improved PPC.

Self and proxy (parents and teachers') reports of child motor competence: A three-year longitudinal study

OBJECTIVE

The aims of this study were to: 1) analyse the longitudinal trends in the evolution of the association between children's actual and perceived motor competence (AMC and PMC, respectively) according to the source of information: children, parents, and Physical Education (PE) teachers; 2) assess whether children, parents, and PE teachers can report on children's AMC longitudinally (considering the children's age, sex, and the type of motor competence).

DESIGN AND METHOD

A sample of 108 typically developing Spanish children (47.12% girls) from five schools participated in this study. AMC and PMC (locomotion, object control and overall MC) data was collected at three time points one year apart. Longitudinal mixed effects models with repeated measures were conducted.

RESULTS

Regardless of the domain of MC, no longitudinal association between children's AMC and PMC was found. Parents also exhibited limited capability to proxy report their children's AMC longitudinally. PE teachers' proxy reports of children' AMC were associated over time with object control and overall level.

CONCLUSION

This study confirms the necessity of specific training in AMC to effectively report on children's motor competence. PE teachers can be seen as a potential source to empower children's AMC and PMC development over time.

Motor competence, physical activity, and perceived motor competence: A relational systems approach

Being and perceiving oneself as proficient in motor skills seems essential for an active lifestyle; conversely, being active and perceiving oneself as proficient may be associated with greater motor competence. By expanding the causal path view about the relationship between active and healthy developmental system elements, this study tested the mediation hypothesis of perceived motor competence in the relationship between motor competence and physical activity - in both ways - and moderation by developmental phase and sex. This cross-sectional study sampled healthy schoolchildren (n = 379; 8.2 ± 1.7 years; 54.9% boys). Physical activity (questionnaire), motor competence (tests included locomotor and object control skills) and perception of motor competence (a pictorial scale) were assessed. Maximum likelihood structural equation models with fit statistics confirmed the mediation in both ways. Unexpectedly, the relationship between motor competence and physical activity was inverse. Sex was a moderating variable (boys). In a systemic relational paradigm of human development, perceived motor competence, motor competence, and physical activity interact in an active and healthy behavioural system, but the complexities of understanding how these elements relate to one another across childhood point to the need for future longitudinal studies.

Qualitative analysis from the social referents perspective of the multidimensional construct of schoolchildren's motor competence

Motor competence (MC) as a multidimensional construct is influenced by motor, cognitive, emotional and social variables. It is also determined by schoolchildren interacting with their own context. Thus pre-adolescence is a sensitive stage in development when physical, emotional and cognitive changes are manifested. By taking this context in accountn, the perception of the social referents close to schoolchildren allows for a deeper understanding of the role and influence of all these variables in a broader MC concept. For this purpose, a qualitative study was conducted by discussion groups and semistructured interviews, respectively, for teachers and family members in Primary Education. The content analysis was carried out according to the main study dimensions, associated with the motor, cognitive, affective-emotional and social domains. Both family members and teachers point out that the affective-emotional level has a stronger impact on the development of motor skills than the motor level. For children to develop their MC, it is necessary to create appropriate contexts in which family members and teachers are the main agents of influence. In conclusion, assessing MC in the educational sphere must have a more comprehensive and broad approach. It is necessary to bear in mind a larger number of variables involved in schoolchildren's motor development to make the most objective assessment possible and, likewise, to promote facilitating environments that help their development.

Youth motor competence across stages of maturity: Perceptions of physical education teachers and strength and conditioning coaches

Physical education (PE) teachers and strength and conditioning (S&C) coaches are well placed to develop motor competence within youth populations. However, both groups’ perceptions of important motor competencies are relatively unknown, especially when considering stage of maturity. Therefore, this study aimed to 1) present PE teachers and S&C coaches’ perceptions of motor competence importance according to stage of maturity; 2) compare perceptions of motor competence between stages of maturity, and between PE teachers and S&C coaches; and 3) explore factors that influence PE teachers and S&C coaches’ perceptions of motor competence importance. Via a mixed-method questionnaire, 47 PE teachers (professional experience = 10.3±6.6 years) and 48 S&C coaches (professional experience = 8.6±4.8 years) rated the importance of developing 21 motor competencies across four stages of maturity (childhood, pre-peak height velocity [PHV], circa-PHV, and post-PHV) using a Likert-scale (1 = not important, 5 = very important). Participants also provided open-ended explanations for their perceptions. Frequency analysis indicated that participants rated a broad range of competencies important, with S&C coaches rating more competencies important than PE teachers across all stages of maturity. Mixed-model analysis highlighted several differences in motor competence importance when comparing perceptions between participant groups, and between stages of maturity for PE teachers and S&C coaches. For example, S&C coaches rated strength-based motor competencies less important during childhood (d = -1.83 to -0.43), while PE teachers rated them less important during childhood (d = -2.22 to -0.42) and pre-PHV (d = -1.70 to -0.51) compared to other stages of maturity. Codebook thematic analysis showed several factors that influenced participant’s perceptions of motor competence importance (e.g., participants understanding of themselves). The findings suggest that multiple environments may be required to adequately facilitate motor competence development amongst youth. Coach education should target misunderstandings around the risks of strength-based activity during early stages of maturity and the benefits of developing strength-based motor competencies across youth populations.

Association between childcare movement behaviour compositions with health and development among preschoolers: Finding the optimal combinations of physical activities and sedentary time

Little is known about how wake-time movement behaviour compositions while in childcare relate to children's health and development. This study aimed to use compositional analysis to examine how childcare movement behaviour compositions were associated with standardised body mass index (zBMI) and physical and psychosocial functioning among children in the preschool setting. A total of 405 preschoolers wore accelerometers during childcare hours to measure their moderate-to-vigorous physical activity (MVPA), light intensity physical activity (LPA) and sedentary time. Compositional regression, isotemporal substitution models, and the "Goldilocks" approach was used to examine how wake-time childcare movement behaviour compositions related to each of the outcomes. Engaging in greater LPA relative to MVPA and sedentary time was associated with higher BMI z-scores, replacing sedentary time or time spent in MVPA with LPA was associated with greater physical functioning, and spending more time in sedentary behaviours relative to overall physical activity was related with greater psychosocial functioning. It is not clear what the optimal wake-time movement behaviour composition while in childcare is for health and development; however, LPA and sedentary time while in childcare may have some benefits. More research is needed to aid the development of childcare-specific guidelines for physical activity and sedentary behaviours.

Promoting Children's Psychomotor Development with Multi-Teaching Didactics

This group randomized control trial examined the dose-response effect of varied combinations of linear and nonlinear pedagogy (enriched physical education with specific program led by specialist vs. conventional physical education led by generalist) for improving first-grade children's motor creativity, executive functions, self-efficacy, and learning enjoyment. We led three physical education classes per group through 12 weeks of combined instruction, based on linear and nonlinear pedagogy: mostly linear (ML; 80% linear, 20% nonlinear; n = 62); mostly nonlinear (MNL; 20% linear, 80% nonlinear; n = 61); and control (C; conventional teaching from generalists; n = 60). MNL improved in (a) motor creativity ability (DMA; 48.7%, 76.5%, and 47.6% for locomotor, stability, and manipulative tasks, respectively); (b) executive functions (working memory and inhibitory control) for RNG task (14.7%) and task errors (70.8%); (c) self-efficacy (5.9%); and (d) enjoyment (8.3%). In ML, DMA improved by 18.0% in locomotor and 60.9% in manipulative tasks. C improved of 10.5% in enjoyment, and RNG task worsened by 22.6%. MNL improvements in DMA tasks, executive functions, and self-efficacy were significantly better than those in C. ML was better than C in DMA task and in executive functions' task errors. Overall, ML and MNL approaches were more effective than conventional generalist teaching (C), and the MNL combination of 80% nonlinear and 20% linear pedagogy was optimal. We recommend that educators favor the MNL approach.

School-Age Children's Actual Motor Competence and Perceived Physical Competence: A 3-Yr Follow-up

PURPOSE

This study examined school-age children's actual motor competence (MC) and perceived physical competence (PC) over 3 yr along with the covariate effects of gender and body mass index (BMI).

METHODS

Participants were 1121 (girls 573, boys 548) children (mean age, 11.26 ± 0.32 yr) from 35 randomly selected public schools across Finland. MC was assessed using three movement tests targeting locomotor, stability, and object control skills, and PC was assessed using the sport competence subscale of the Physical Self-Perception Profile via four-phase monitoring.

RESULTS

MC and PC remained stable over time. Of the three variables, locomotor skills showed the strongest association with PC. Lower BMI was associated with advanced MC skills and a less steep decrease in locomotor and stability skills over time.

CONCLUSIONS

The acquisition of fundamental motor skills in childhood and early adolescence is a prerequisite for enhancing MC and PC. The contribution of locomotor skills to PC indicated that versatile lower limb strength, speed, dynamic balance, and movement skills are important for positive subjective beliefs about PC capability. Increasing the MC skills of the children in most need, particularly those with high BMI scores, merits special attention.

Actual and Perceived Motor Competence, Cardiorespiratory Fitness, Physical Activity, and Weight Status in Schoolchildren: Latent Profile and Transition Analyses

Engagement in physical activity plays a central role in the prevention and treatment of childhood overweight/obesity. However, some children may lack the skills and confidence to be physically active. This 3-year follow-up study aimed to form profiles based on cardiorespiratory fitness, actual motor competence, perceived motor competence, physical activity, and weight status, and to examine if these profiles remain stable from late childhood to early adolescence. All these variables were annually assessed in 1,162 Finnish schoolchildren (girls = 583 and boys = 564, Mage = 11.27 ± 0.32 years). Latent profile analysis was used to identify profiles and latent transition analysis to examine the stability of latent statuses. Three profiles were identified: normal weight with high movement, normal weight with low movement, and overweight–obese with low movement. Profile memberships remained relatively stable over time, indicating that children with low actual and perceived motor competence, cardiorespiratory fitness, and physical activity in late childhood also tended to exhibit these characteristics in early adolescence.

The Inter-Rater and Intra-Rater Reliability of the Actual Aquatic Skills Test (AAST) for Assessing Young Children's Motor Competence in the Water

As children’s actual aquatic skills are important for the prevention of drowning as well as their engagement in lifelong aquatic physical activity, researchers and practitioners should be able to assess this vital concept accurately and reliably. Therefore, this study aimed to investigate the inter-rater and intra-rater reliability of the Actual Aquatic Skills Test (AAST), consisting of 17 different test items for the assessment of young children’s motor competence in the water. Six raters received a training and evaluation session on scoring the AAST, after which five of them assessed four test videos (of various children (n = 38) performing the test items) twice, with one to two weeks in between (i.e., test and re-test). Inter-rater and intra-rater reliability were determined per test video and for the different AAST test items across videos using Gwet’s Agreement Coefficient 2 (Gwet’s AC2). The Gwet’s AC2 for inter-rater reliability at the test varied from 0.414 to 1.000, indicating a moderate to perfect agreement between raters. For intra-rater reliability, it ranged from 0.628 to 1.000, demonstrating a good to perfect agreement between test and re-test scoring. In conclusion, the AAST is a promising tool to reliably assess young children’s actual aquatic skills in an indoor swimming pool.

Systematic Review and Meta-Analysis of the Relationship between Actual Exercise Intensity and Rating of Perceived Exertion in the Overweight and Obese Population

The number of overweight (OW) and obese (OB) children, adolescents, and adults has increased globally. Exercise intensity, both actual and perceived, is a significant factor in a variety of health-related investigations and rehabilitation trainings. Despite this, literature on the connection between actual exercise intensity and the rating of perceived exertion (RPE) in overweight and obese populations is lacking. A systematic review, meta-analysis, combined analysis of variance (Brown-Forsythe ANOVA), and Spearman correlation were performed to fill this gap. After preliminary assessments, ten studies were classified as having a low risk of bias and a degree of heterogeneity (I² = 34%; p = 0.05). The RPE scores (F = 0.032; p = 0.859), physiological index (percentage of maximal heart rate (%HR_max) (F = 0.028; p = 0.869), and percentage of maximal oxygen uptake (%VO_2max) (F = 2.434; p = 0.136) demonstrated consistency without being significantly different between the normal weight (NW) and OW/OB groups. The RPE scores varied by age (NW (coefficient values) = 0.677 ***, OW = 0.585 **), as well as by indoor temperature (OW only, coefficient values = 0.422 *), body mass index (NW (coefficient values) = 0.516 **, OW = 0.580 **), and test time (NW only, coefficient values = 0.451 *). We conclude that RPE is appropriate for the following OW and OB people: (1) those who are older than 21.5 (the lowest age in the group of ≥18) years old and younger than 58.6 (the highest age in the group of ≥18) years old, without any other diseases, and (2) those who engage in low-intensity exercise while maintaining a standard indoor temperature. Future studies may address alternative techniques for increasing the reliability of longitudinal comparisons and gender comparisons, as well as investigate other possible confounding factors.

Aquatic Physical Literacy: The Effectiveness of Applied Pedagogy on Parents' and Children's Perceptions of Aquatic Motor Competence

The goal of swimming school during early school age is to promote physical literacy. According to linear or non-linear pedagogy, a linear or non-linear approach teaching style can be used. The aim of our study was to investigate whether a different teaching methodology, as in using a teacher-centered approach (linear pedagogy), or a student-centered approach (non-linear pedagogy), could differently influence the perceptions of aquatic activity of children and parents. Parents of 100 children (53 females and 47 males, age 5.9 ± 0.3 years old) participating in the study were previously interviewed to ascertain their expectations regarding the swimming course. Participants were in a medium-high social context. Subsequently, considering the data of the incoming aquatic motor competence's tests, children were divided into a linear (LI) and non-linear (NL) pedagogy group. A total of 4 instructors were enrolled. Upon completing the swimming course, the aquatic motor competence's test was repeated, a pictorial scale of perceived motor competence was administered, and a questionnaire regarding the course was proposed to children's parents. Physical development and learn to swim resulted two of the most important reasons leading parents to choose swimming courses. LI achieved greater progress than the NL in actual motor competence (A.M.C.), while NL perceived a higher aquatic motor competence (P.M.C.) in 7 out of 10 items of the pictorial scale. Parents of children in LI, gave greater importance to the teacher's role, while NL's parents pointed the acquisition of children's abilities as pivotal. In conclusion, NL approach was more appreciated by children, while LI method was more rewarding for parents because initial expectations were satisfied.

What factors relate to three profiles of perception of motor competence in young children?

The study aims were to 1) examine profiles of perception of motor competence (PMC) in relation to actual motor competence (AMC), i.e. under-estimators (UEs), realistic estimators (REs) and over-estimators (OEs) and 2) investigate associations between the profiles and selected socioecological factors at the individual, family and environmental levels. PMC (Pictorial Scale of Perceived Movement Skill Competence) and AMC (Test of Gross Motor Development-Third Edition) were administered to a representative sample of children from 37 childcare centres in Finland (n=441;6.2±0.6yrs;52% boys). Socioecological factors were investigated using a parental questionnaire. The three profiles were formed based on age- and gender-adjusted PMC and AMC z-scores. Multinomial logistic regression showed that OEs (n=81; p=0.04) tended to be younger than REs (n=306; p=0.04) and UEs (n=54; p=0.03). Parents of OEs reported more child health and developmental issues than parents of REs (p=0.03). Parents of UEs self-reported providing more support for physical activity than parents' of REs (p=0.04). REs tended to live in denser population areas than UEs (n=54; p=0.03). Whilst PMC profiles revealed some socioecological differences, future research needs to focus on a broader range of potential correlates and untangle methodological analyses challenges to deepen the knowledge about PMC development in children.

Effects of an 8-Week Intervention Targeting the Veridicality of Actual and Perceived Motor Competence Among Irish Adolescents in Project FLAME

High levels of perceived motor competence and low levels of actual motor competence in youth populations have been reported world-wide. Both perceived and actual motor competence have been deemed independent correlates of health and physical activity (PA) behavior, and past research has indicated that their alignment may be linked to more consistent PA. Moreover, there is potential for a movement-based intervention to strengthen the alignment between perceived and actual motor competence, perhaps then guiding future health, PA, and community sport engagement globally. Thus, the objective of this study was to investigate the effectiveness of an 8-week movement-based intervention on increasing the alignment (i.e., veridicality) between PMC and AMC among Irish adolescent youth. We collected data on adolescents (n = 324; females = 149; M age = 14.5, SD = 0.88 years) across six second-level schools in Ireland, including measurements of actual and perceived, motor competence at pre- and post-intervention. We observed low levels of actual in contrast to high levels of perceived motor competence. We found a small but significant veridical alignment between perceived and actual motor competence, but there was no intervention effect on alignment. Future research should prioritize a longer intervention duration that targets student learning and understanding in order to develop veridical perceptions in adolescents that might sustain their participation in PA.

Development of accelerometer-based light to vigorous physical activity in fitness profiles of school-aged children

This study examined the developmental trajectories of light (LPA) and moderate-to-vigorous physical activity (MVPA) in fitness profiles derived from motor competence, perceived motor competence, health-related fitness, and MVPA behavior. Locomotor, stability, and object control skills, muscular and cardiovascular fitness, and physical activity were assessed in 510 (girls 285 and boys 225) Finnish school-aged children (M_age  = 11.26 ± 33 years) over three years. Physical activity was measured using hip-mounted accelerometers. Fitness profiles were identified using latent profile analysis, and the development of physical activity levels across four assessments was analyzed with latent growth curve models. Results showed that (1) three homogeneous profiles were identified: At-risk, Intermediate, and Desirable; (2) the Desirable group was more physically active than the other groups, the Intermediate group was more physical active than the At-risk group; and (3) LPA decreased similarly over time, while MVPA remained stable in all three profiles. Initial more advanced motor competence, perceived motor competence, health-related fitness, and higher MVPA behavior were associated with higher levels of long-term LPA and MVPA. This finding supports the importance of motor competence skills acquisition in the early school years. Attention should also be paid to increasing engagement in light physical activities, especially in inactive or insufficiently active children with low motor competence skills.

The impact of resistance training on strength and correlates of physical activity in youth

Resistance training (RT) may have a positive impact on specific correlates of physical activity (PA) in inactive and/or obese youth, with strength as a possible underlying mechanism. The aim of this study was to investigate this. Twelve participants (aged 8.9 ± 1.0 years) were assigned to an experimental group (EG) or control group (CG). Pre and post intervention assessments for strength, physical self-perceptions (PSPs), weight status, fundamental movement skills (FMS), and PA levels were completed. The EG participated in a twice-weekly 10-week RT programme. There were significant group x time interactions for FMS (CAMSA total P = 0.016, CAMSA skill score P = 0.036) and stretch stature (P = 0.002) (EG larges changes than the CG). Large effect sizes for the differences in change scores between the EG and CG were evident for CAMSA total score (Hedges' g = 0.830, P = 0.138), CAMSA skill score (Hedges' g = 0.895, P = 0.112) and relative strength (Hedges' g = 0.825, P = 0.140). This study demonstrated that a 10-week RT intervention has a positive effect on strength and FMS, and may also benefit weight status and PSPs. This study supports the development of RT interventions to develop these correlates, and increase PA levels.

Through the Looking Glass: A Systematic Review of Longitudinal Evidence, Providing New Insight for Motor Competence and Health

Introduction

In 2008, a conceptual model explaining the role of motor competence (MC) in children’s physical activity (PA), weight status, perceived MC and health-related fitness was published.

Objective

The purpose of the current review was to systematically compile mediation, longitudinal and experimental evidence in support of this conceptual model.

Methods

This systematic review (registered with PROSPERO on 28 April 2020) was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Separate searches were undertaken for each pathway of interest (final search 8 November 2019) using CINAHL Complete, ERIC, Medline (OVID), PsycINFO, Web of Science Core Collection, Scopus and SportDiscus. Potential articles were initially identified through abstract and title checking (N = 585) then screened further and combined into one review (n = 152), with 43 articles identified for extraction. Studies needed to be original and peer reviewed, include typically developing children and adolescents first assessed between 2 and 18 years and objective assessment of gross MC and at least one other variable (i.e., PA, weight status, perceived MC, health-related fitness). PA included sport participation, but sport-specific samples were excluded. Longitudinal or experimental designs and cross-sectional mediated models were sought. Strength of evidence was calculated for each pathway in both directions for each domain (i.e., skill composite, object control and locomotor/coordination/stability) by dividing the proportion of studies indicating a significantly positive pathway in the hypothesised direction by the total associations examined for that pathway. Classifications were no association (0–33%), indeterminate/inconsistent (34–59%), or a positive ‘+’ or negative ‘ − ’ association (≥ 60%). The latter category was classified as strong evidence (i.e., ++or −−) when four or more studies found an association. If the total number of studies in a domain of interest was three or fewer, this was considered insufficient evidence to make a determination.

Results

There was strong evidence in both directions for a negative association between MC and weight status. There was strong positive evidence for a pathway from MC to fitness and indeterminate evidence for the reverse. There was indeterminate evidence for a pathway from MC to PA and no evidence for the reverse pathway. There was insufficient evidence for the MC to perceived MC pathway. There was strong positive evidence for the fitness-mediated MC/PA pathway in both directions. There was indeterminate evidence for the perceived MC-mediated pathway from PA to MC and no evidence for the reverse.

Conclusion

Bidirectional longitudinal associations of MC with weight status are consistent with the model authored by Stodden et al. (Quest 2008;60(2):290–306, 2008). However, to test the whole model, the field needs robust longitudinal studies across childhood and adolescence that include all variables in the model, have multiple time points and account for potential confounding factors. Furthermore, experimental studies that examine change in MC relative to change in the other constructs are needed.

Does Perceived Competence Mediate between Ball Skills and Children's Physical Activity and Enjoyment?

The major purpose of this study was to examine the potential mediating role of perceived motor skill competence on relationships between actual ball skills and children’s physical activity (PA) and PA enjoyment. A total of 294 students (M_age = 10.96 ± 0.76; 51.7% boys) from three elementary schools completed validated questionnaires assessing their perceived competence, self-reported PA, and PA enjoyment. Students’ actual ball skills (i.e., basketball, overhand throwing, striking) were measured by PE Metrics^TM. Correlation analyses showed positive relationships among the study variables (rs ranging from 0.12 to 0.56). The structural equation modeling (SEM) analyses demonstrated that the mediation model produces a goodness-of-fit to the data: χ²/df = 52.03/32; CFI = 0.96; NFI = 0.90; IFI = 0.96, RMSEA = 0.05, SRMR = 0.04. Path coefficients suggested that actual ball skill competence was strongly associated with perceived competence (β = 0.36, p < 0.01), which in turn significantly predicted PA (β = 0.29, p < 0.01) and PA enjoyment (β = 0.35, p < 0.01). The findings highlight that ball skills significantly impact students’ perceived competence, positively and indirectly affecting their PA and PA enjoyment. This study provides empirical evidence that recommends intervention strategies aimed at fostering elementary school students’ PA and PA enjoyment.

Differences between Young Children's Actual, Self-perceived and Parent-perceived Aquatic Skills

As drowning is a leading cause of unintentional injury/death in children worldwide, perceptions of their actual aquatic skills are of critical importance. Children's self-perceptions may influence the risks they take, and parental perceptions may influence the degree of supervision deemed to be necessary for children in and around water. Accordingly, we examined the differences between young children's actual, self-perceived and parent-perceived aquatic skills. Using a three-way repeated measures ANCOVA, we analyzed data from 134 child-parent dyads (56.0% boys; M age = 7.1, SD = 1.1 years; and 71.6% mothers). We measured self and parental perceptions of the child's aquatic skills with the 'Pictorial Scale of Perceived Water Competence' (PSPWC), and we applied the exact same 17 test items of the PSPWC to assess the child's actual aquatic skill level in the water. Controlling for years of swimming school experience, within-subject differences between the total scores on the 'Actual Aquatic Skills Test' (AAST) and both the child- and parent-completed PSPWC indicated lower than actual estimates of the children's aquatic skill level. The degree of disagreement against the AAST was more pronounced in parents than in 6-7 year-old children but was similar between parents and 8-9 year-old children, with these patterns being evident regardless of the children's sex. Our study contributes to an ongoing validation of the PSPWC and represents a key advance in assessing and comparing children's actual and perceived aquatic skill competence, using perfectly aligned instruments. Future research and practice might explore children's actual aquatic skills in different contexts (e.g., open water), include perspectives of non-parent caregivers and assess perceived and actual water competence across development.

Parental and Peer Support Matters: A Broad Umbrella of the Role of Perceived Social Support in the Association between Children's Perceived Motor Competence and Physical Activity

(1) Background: This study aimed to examine the role of social support in the relationship between perceived motor competence (MC) and physical activity (PA), according to the conceptual model of Motor Development. (2) Methods: Participants were 518 students (46.5% girls), 8–12 years old. By using a structural equation modeling approach, path analysis was used to test the actual-perceived MC relationship and the mediating influence of social support on the perceived MC–PA relationship. Analyses were done with age and sex as covariates. (3) Results: The results showed a good model fit (CFI = 0.98; RMSEA = 0.07; SRMR = 0.02), where actual MC was positively associated with perceived MC (ß = 0.26, p < 0.001), which in turn was positively related to social support (ß = 0.34, p < 0.001). The model showed the direct social support-PA path (ß = 0.42, p < 0.001) and the indirect path from perceived MC through social support to PA (ß = 0.14, p < 0.001). (4) Conclusions: This study confirms that social support mediates the perceived MC–PA relationship. As such, it is not only important to build and develop children’s actual and perceived MC, but also to promote social support for PA engagement.

Profiling children longitudinally: A three-year follow-up study of perceived and actual motor competence and physical fitness

Longitudinal designs enhance our understanding of children's development and its influence on movement behaviors and health. This three-year follow-up study aimed to develop profiles according to perceived and actual motor competence (MC) (locomotion, object control, and overall) and physical fitness in boys and girls longitudinally including children's temporal migrations among clusters in terms of profiling trends. A secondary aim was to compare physical activity participation and weight status at each time point according to these profiles. One hundred and four typically developing Spanish children (45.8% girls) between 4 and 9 years old at baseline participated in this study. Data were collected at three time points one year apart, between January 2016 and May 2018. A self-organizing map and K-means cluster analysis were used to classify and visualize the values and temporal trajectories longitudinally. The study of the profiles in three consecutive years revealed five profiles, three for boys [ie, profile 1 (aligned-high), profile 2 (aligned-partially-low perception-medium actual MC and fitness), and profile 3 (non-aligned-medium perception-low actual MC and fitness)]; and two for girls [ie, profile 4 (aligned-high) and profile 5 (aligned-low)]. For highly perceived and capable children, boys (profile 1) and girls (profile 4), there was a tendency for higher physical activity participation and lower body mass index and waist circumference over time compared to their counterparts who had medium and/or low levels in perception and actual MC and fitness (P < .05). As children age, those with low values in perceived and actual MC and fitness in object control skills will present a higher probability of maintaining unhealthy lifestyles. So, prior intervention, children's profiles identification should be analyzed according to the type of MC.

Movement skills, perception, and physical activity of young children: A mediation analysis

BACKGROUND

Fundamental movement skill proficiency and perceived physical competence have been shown to influence the physical activity of children. However, the mechanisms and patterns of their relationships in early childhood need to be investigated. This study examined the direct and indirect effects of fundamental movement skills and the mediating role of perceived physical competence on the physical activity of young children.

METHODS

Participants were 4- to 6-year-old children (N = 230; 121 girls, 109 boys). Fundamental movement skill components (i.e., locomotor, object control) were measured using the Test of Gross Motor Development-2; perceived physical competence was measured using the physical skills domain of the Pictorial Scale of Perceived Competence for young children; and physical activity was monitored using pedometers over a 5-day period (n = 115). Conditional process analysis was performed to examine mediation.

RESULTS

Object control skill proficiency had a significant positive effect on perceived physical competence (B = 0.28, P = 0.02), and a significant positive effect on daily step counts (B = 0.18, P = 0.04). Perceived physical competence had a significant negative effect on daily step counts (B = -0.31, P = 0.003) and mediated the indirect effect of object control skills on daily step counts (B = -0.09, 95% confidence interval: -0.17 to -0.002).

CONCLUSIONS

Object control skill proficiency had a significant direct effect on physical activity, and perceived physical competence mediates an indirect effect. The findings contribute to the evidence base supporting the development of object control skills as a factor that enables adequate physical activity in young children.

The Validity and Reliability of Scales to Measure Perceived Movement Skill Competence in Iranian Young Children

The aim of this study was to determine the validity and reliability of the Perceived Movement Skill Competence scales for Iranian children. In particular, the scales aligned with the second and third versions of the Test of Gross Motor Development and the active play skills. The total sample was 314 children aged 4–8 years (Mage = 6.1 years, SD = 1.1). From this, a random sample of 74 were recruited for face validity. The data from the remaining 240 children were used to establish construct validity using Bayesian Structural Equation Modeling. The data from a second random subsample of 126 children were used to investigate Perceived Movement Skill Competence reliability using ordinal alpha coefficients and intraclass correlations coefficients. The majority of children correctly identified the skills and understood most of the pictures. Internal consistency was very good (from 0.81 to 0.95) for all scales and subscales. Test–retest reliability was excellent with intraclass correlation coefficient values above .85. For construct validity, the initial hypothesized models for three-factor (i.e., locomotor, object control, and play skills) and two-factor (i.e., locomotor and object control) models showed a reasonable fit. The pictorial scales for Perceived Movement Skill Competence are valid and reliable for Iranian young children.

Perceived movement skill competence in stability: Validity and reliability of a pictorial scale in early adolescents

Perceived motor competence (PMC) is important to health as it mediates the association between actual motor competence (AMC) and physical activity. Many instruments assess the broader construct of physical self-perception but no scale has been developed to assess PMC in stability. The aim of this study was to develop and analyze the reliability and validity of a new pictorial PMC in stability skill assessment when completed by early adolescents. A Delphi method showed ≥70% of experts' consensus in the seven proposed items. A sample of 904 students (11-14 years old) self-reported PMC in locomotion, object control, and stability using two pictorial scales: Perceived Movement Skill Competence (PMSC) and the newly developed Stability (PMSC_Stability). The Körperkoordinations test for Kinder (KTK) was also administered as a measure of AMC in skills that utilize stability. Two different subsamples were randomly assigned to criterion validity and reliability assessments. Spearman's correlation, confirmatory factor analysis, and a general linear model for sex and age were conducted. The internal consistency (α) and test-retest (intraclass correlation coefficient) reliability values were good (>0.70). A single-factor latent model represented stability and did not differ by sex. Stability perception was associated with AMC (rho = 0.51). Stability is important to the performance of many movement skills (eg, single-leg balance or moving on a narrow surface). Understanding which adolescents have poor stability perception could highlight stability as an area that needs targeting in order to increase physical activity and sport participation.

Differences in Weight Status and Autonomous Motivation towards Sports among Children with Various Profiles of Motor Competence and Organized Sports Participation

This study aimed (1) to identify profiles in children based on actual motor competence (AMC), perceived motor competence (PMC), and organized sports participation (OSP), and (2) to examine differences among these profiles in weight status as well as autonomous motivation towards sports. Children’s (N = 206; 112 boys; M_age = 10.83 ± 0.92 years) AMC, PMC, OSP, weight status, and autonomous motivation towards sports were measured using validated assessment tools. Cluster analyses identified three profiles with completely convergent levels of AMC, PMC, and OSP and three profiles with partially convergent levels. Children in the convergent profiles with average to high levels of AMC, PMC, and OSP had the most optimal profile, as they combined a healthier weight status with elevated levels of autonomous motivation, while the opposite was true for children with low levels on all three cluster-variables. Partially convergent profiles showed that AMC and PMC appear crucial for weight status, as profiles with relatively low levels of AMC and PMC had the highest weight status, independent of their OSP levels. Overall, the findings highlight the importance of promoting AMC, PMC, and OSP simultaneously to help children in achieving a healthy weight status and being autonomously motivated towards OSP.

What Factors Help Young Children Develop Positive Perceptions of Their Motor Skills?

A positive perception of motor skills is important for physical activity participation. The aim was to investigate which modifiable factors predict children’s perceived motor skills. Mothers completed questionnaires when their child was 3.5 and 5 years old. At 5 years old, the children’s perceived motor competence (PMC) was assessed. Separate linear regression models (up to 300 children) examined which factors at each time point predicted children’s PMC, adjusted for relevant confounders. Multivariate models were then run with factors associated (p < 0.10) with perception. At 3.5 years, the time spent with same age and older children (both higher tertiles) and parental physical activity facilitation (sum of facilitation in last month, e.g., taking child to park) were initially associated with higher perception. Dance/gymnastics participation were associated with lower perceptions. Other child behaviours, maternal beliefs, play equipment, and swimming lessons were non-significant. In the final prospective model (n = 226), parental physical activity facilitation when child was 3.5 years old was the only factor to predict PMC. No factors were significant for the cross-sectional analyses at 5 years. Perceptions are formed based on past experiences which may explain why factors at 3.5 years rather than current experiences (when children were 5 years old) were associated with childhood perceptions.

A Longitudinal Examination of the Accuracy of Perceived Physical Competence in Middle Childhood

Children who underestimate their physical abilities have lower motivation, higher anxiety, and lack of understanding as to why they may be succeeding or struggling in sports settings, which can result in withdrawal from physical activities. Theoretically, middle childhood is a time when perceptions of physical competence (PPC) become more accurate as children develop the cognitive capacity to interpret new sources of feedback and develop a realistic sense of their physical abilities. The purpose of this study was to investigate the extent to which accuracy of PPC changed from grade 2 to grade 4. Participants were 238 boys and girls (Mage = 7.8 yrs) from eight participating elementary schools in Victoria, British Columbia, Canada. The Test of Gross Motor Development–Second Edition was used to assess motor skills. PPC were assessed using the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (for grade 2) and the Self-Perception Profile for Children (for grades 3 and 4). Results revealed that participants who underestimated or overestimated their physical competence in grade 2 saw an improvement in accuracy, and, by grade 4, had similar accuracy scores to their peers who were considered ‘accurate’ estimators. These results reinforce theory that suggests PPC become more accurate in middle childhood.

Does level of motor competence affect the associations between identity health and self-perceptions in adolescents?

BACKGROUND

Adolescence is a particularly important time for the development of self-perceptions and identity as many environmental and personal factors are influential. One relatively unexplored factor is level of motor competence.

AIM

To examine the relationship between identity health and self-perceptions in male and female adolescents with low motor competence (LMC) compared to typically developing (TD) adolescents.

METHOD

Adolescents (N = 160, 64.4% males, M_age = 14.45 yrs., SD = 0.75) completed the Adolescent Motor Competence Questionnaire (AMCQ), Assessment of Identity Development in Adolescence (AIDA), and Harter's Self-Perception Profile for Adolescents (SPPA). Based on the AMCQ score, the sample was grouped into LMC and TD. Pearson's product moment correlations between the AIDA and SPPA subscales were derived for gender, competence groups, and gender x competence sub-groups.

RESULTS

Overall, males had lower AIDA scores (healthier identity) than the females and significant associations with all self-perception domains. For females, only scholastic and social competence, physical appearance, behavioural conduct, close friendship and Global Self-worth (GSW) domains were significantly related to their AIDA score. The adolescents in the LMC group had higher AIDA scores (less-healthier identity) and fewer self-perception domains [scholastic competence, physical appearance, behavioural conduct, close friendships and GSW] were associated to their AIDA scores. For the TD group, all self-perception domains were significantly correlated with their AIDA scores. When grouped by gender and motor competence, the TD males had the healthiest identity scores which were strongly associated with all self-perception subdomains. For males with LMC, only scholastic competence, behavioural conduct and GSW domains were significantly related with their identity score. Females from both competence groups reported significant associations between physical appearance, close friendships, behavioural conduct, and social competence domains with their identity scores. Scholastic competence was also significantly associated with identity only for females with LMC.

CONCLUSION

Positive self-perceptions across a range of domains are associated with a healthier identity, but differ according to level of motor competence and gender. For those with LMC, the self-perception subdomains unrelated to physical activity and sport, such as school-based aspects were associated with a healthier identity. These findings should guide school based interventions to provide support in these domains in order to strengthen self-worth and identity health.

A Causal Pathway of Physical Activity to Motor Competence in Childhood:Evidence from a School-based Intervention

This study aimed to examine whether changes in physical activity (PA) after an 8-week pedometer-based intervention would result in changes on motor competence through competence beliefs towards physical education (PE). The study also evaluated whether the hypothesized causal pathway differed by gender. Participants were 259 children (Mean _age  = 10.88, SD =.78), randomly allocated to three intervention groups. Children's PA, competence beliefs towards PE, and motor competence were measured at pre- and post-tests. Significant relationships between PA and competence beliefs towards PE were found at pre- and post-tests. The magnitude of the relationship between competence beliefs towards PE and motor competence was larger at post-test than at pre-test (.33 vs.20). The structural invariance test suggested that the differences between boys and girls for the hypothesized models were insignificant (CMIN = 15.97, df = 12; p =.193). In general, the results suggest that changes on PA may cause changes in competence beliefs towards PE, which could result in changes on motor competence in middle to later childhood, regardless of gender. These data offer the possibility of using competence beliefs towards PE as a mediator in PA interventions designed to increase motor competence in childhood.

Associations between Motor Competence, Physical Self-Perception and Autonomous Motivation for Physical Activity in Children

Research indicates that children and adolescents gradually participate less in physical activity with age. Several factors are associated with children's physical activity levels, such as motor performance, self-perception of athletic competence and motivation to physical activity. To gain a better understanding of the factors of importance for behavior related to an active lifestyle, the purpose of this study was to investigate the association between motor competence, physical self-perception and autonomous motivation and to examine to what extent this association may vary by sex. The sample consisted of 101 children, whose average age was 11.7 years (SD = 0.57), 53 boys and 48 girls. All subjects were measured on motor competence, physical self-perception and autonomous motivation for physical activity. The results indicate a low positive relationship between motor competence and physical self-perception for the entire sample and among girls. There is also a significant correlation between autonomous motivation and physical self-perception. No significant correlations were found between autonomous motivation and motor competence. The association between physical self-perception and autonomous motivation suggests that psychological factors play an important role in children's participation in physical activity.

Investigating the Age-Related Association between Perceived Motor Competence and Actual Motor Competence in Adolescence

Irish adolescents have been found to possess high perceptions of motor competence. However, there is an evidential value to investigating the strength of the relationship between adolescent perceptions of motor competence and their low levels of actual motor competence. The purpose of this research was to gather data on the fundamental, functional, and perceived motor competence in adolescents, differentiated by year group, to discern if participants could assess their perceptions of ability. Data were collected on adolescents (N = 373; mean age: 14.38 ± 0.87 years; 47.7% female) across six second-level schools in Ireland, including measurements of fundamental movement skills, functional movement, and perceived motor competence. Poor levels of fundamental and functional movement were observed, with significant differences between year groups detected. Participants in 1st year scored the highest in overall fundamental movement skills; however, for overall functional movement, 3rd-year participants scored highest. High levels of perceived motor competence were reported across the entire sample. These scores did not align with actual motor competence, nor did any alignment between these measurements improve with aging, countering theorized age-related associations. Future research should target low levels of actual motor competence while emphasizing the cognitive aspects of movement to ensure greater accuracy between actual and perceived motor competence.
