Background
Physical literacy (PL) is considered as an important prerequisite for lifelong physical activity participation [
1] and assessing standards for quality physical education [
2]. The concept of PL is defined as the “motivation, confidence, physical competence, knowledge and understanding to value and take responsibility for engagement in physical activities for life” (p.12) [
3]. As a multifaceted construct, PL has been explored within different epistemologies. This multidimensional concept emphasizes an individual can lead a fulfilling life encompassing “the motivation, confidence, physical competence, knowledge and understanding to maintain physical activity” through enriching embodied experiences [
4]. PL nurtures the disposition of an individual to establish a purposeful physical activity for pursuing an active lifestyle [
5]. A consensus on the importance of PL in promoting physical activity and active living is attained in several countries, such as Canada, Australia and the UK, to pioneer large-scale programs innovatively in public health settings [
6]. Since PL has been gaining popularity in the areas of sports and health in response to the global decline of children’s participation in physical activity, many countries have incorporated the concept of PL into their educational systems to create a renewed focus on physical education in schools. For example, SHAPE America implementing national standards for health and PE replaced the term “physically educated” with “physically literate” in the K-12 Physical Education National Standards to emphasize the importance of maintaining lifelong physical activity for children [
7]. Meanwhile, PL has worked as a guiding ideology for quality PE in Chinese schools, and scholars in China have embraced the PL concept as an important assessing standard for evaluating PE outcomes. The concept of PL has recently been interpreted by Chinese scholars as “a comprehensive disposition encompassing motivation, confidence, physical competence, knowledge and understanding to benefit the survival and development of the whole person during the life course” [
8]. This is consistent with the key components of the “Whiteheadian” definition of PL. PL has also been promoted to PE teachers through continuing professional development programs held by the Education Bureau in Hong Kong [
9]. Considering the multidimensional components of PL to date, the measure of actual levels of PL is especially emphasized through developing PL assessments. For example, several studies have consistently assumed that the dimensions of PL involving behavioral, psychological and physical domains were (theoretically and practically) distinct but integrated [
6], and “cannot be assessed / measured in a traditional and conventional sense using simplistic and linear methods” (p.681) [
10]. Therefore, an appropriate physical skill evaluation combining all parameters of PL was required to meet this need in response to which Longmuir and colleagues have developed the Canadian Assessment of Physical Literacy (CAPL) [
11]. CAPL is the first valid, reliable and comprehensive protocol in Canada for monitoring actual levels of PL among Canadian children [
11]. The development progress of the assessment underwent a three-round Delphi expert review and then confirmed the model as the CAPL [
12]. Recently, the research group has updated the model in a second edition, the CAPL-2. This is a more streamlined version that aims to be more easily utilized in schools by PE teachers [
13]. The four domains of CAPL-2 are Physical Competence, Daily Behavior, Knowledge and Understanding, and Motivation and Confidence. Numerous studies have adopted CAPL/CAPL-2 in exploring children’s actual PL levels and the relationship between their PL and physical activity [
14‐
16].
PL perceptions may also be important for children’s physical activity. Perceived physical literacy (perceived PL) has been constructed through the development of the Perceived Physical Literacy Instrument (PPLI) in PE teachers and adolescents within the educational setting [
17,
18]. The validated instrument identified perceived PL as an individual’s perceived capability in pursuing a healthy and active lifestyle [
19], which includes three attributes: (1)
Knowledge and Understanding; (2)
Self-expression and Communication with others; and (3)
Sense of self and Self-confidence. Choi and colleagues have demonstrated the predictive effect of perceived PL attributes on physical activity levels among Hong Kong adolescents [
20]. They assume that the attribute of
Knowledge and Understanding is held by individuals who describe and evaluate their movement experiences and physical activity lifestyle and how to improve their movement and all-round health; the attribute of
Self-expression and Communication with others could encourage individuals to react to interpersonal interactions through feeling and responding while participating in physical activity; while the attribute of
sense of self and self-confidence enables adolescents to gain rewarding physical activity experiences to develop on their PL journey. This is partially supported by the research in which a significant positive association was reported between physical activity and perceived PL in adolescents and these attributes generated a variance of 5.2% in physical activity levels [
20].
Given that children with low actual PL levels and low PL perceptions are less likely to participate in physical activity compared to their physically-literate peers [
15,
20], it is important to understand how perceptions might be related to actual PL. However, no research has explored the associations between actual PL and the perceptions of PL, in spite of the importance of PL in predicting children’s physical activity levels. For the purposes of understanding how well children’s PL perceptions could reflect their actual PL levels, it is important that the constructs are aligned in a similar way. As such, the attributes of the perceived PL, including
Knowledge and Understanding, Self-expression and Communication with others, and Sense of self and Self-confidence, have been reinforced with the core attributes of motivation, confidence, physical competence, and interaction with the environment emphasized in Whitehead’s (2010) definition. The perceived PL has been echoed with several of the kernel attributes of the PL concept [
4]. Children develop their level of PL through embodied experiences as they grow during their life journey. CAPL provides an overall PL assessment for 8- to 12- year-old children. In Hong Kong, this age group of children are primary school aged children. Current assessment methods of PL have been intended mainly for use in the school environment [
21]. In sport and education systems, children are mostly grouped by age as an administrative strategy for comparing age-adjusted competition and learning opportunities [
22,
23]. However, research has indicated that age grouping by a certain cut-off date promotes a relative age difference which has an impact on children who are born on the “early side” of the cut-off date [
24]. The differences are known as the relative age effect (RAE) bias [
25,
26]. A great deal of research has shown that RAE is associated with children’s performance in the testing of fitness and fundamental movement skills [
24,
27]. Baker, Horton, Robertson-Wilson, and Wall have also assumed that RAE works as a maturational factor to influence an athlete’s development in the elite level [
28]. Since the attributes of physical competence and motor skills and fitness tests were included in CAPL-2 assessments, the influence of RAE on children’s objective PL and perceptions of PL should be considered [
29]. Despite the important influence RAE generates in the development of children’s PL, few studies have examined the potential effect of RAE on the PL perceptions and the child’s actual PL levels. Understanding the relationship between actual level of PL and perceived PL, and how associations may differ according to their RAE and by sex, could inform interventions aiming to improve children’s PL, and therefore hopefully decrease health risks related to physical inactivity.
The purpose of this study was to explore the associations between perceived and actual levels of PL in primary school-aged Chinese students, and to examine RAE, gender differences and interaction effect (2X4) in perceived and actual levels of PL.

In general, significant correlations were found between children’s perceptions and their actual level of PL in both boys (r = .46, p < .01) and girls (r = .41, p < .01). Among boys, the lowest correlation coefficients were found in the domain of Knowledge and Understanding of actual PL. Significances were only found in the total scores of CAPL-2 (r = .34, p < .01) and the attribute of Self-expression and Communication with others in perceived PL (r = .16, p < .05). Among girls, moderate to high correlations (r value from .15 to .90) were found in all the attributes with both global perceived PL and actual PL. Different from boys, a low to moderate significance in girls was found in the domain of Knowledge and Understanding with Sense of self and Self-confidence (r = .18, p < .05), and with Physical Competence (r = .41, p < .01). Further, girls’ correlations between Self-expression and Communication with others and Daily Behavior and Physical Competence were not significant according to the results.
The multivariate analyses of variance (MANOVA) tests were computed for examining the between-gender differences and between-relative age effect (RAE) on both perceived and actual levels of PL and their interaction effect (2 × 4). Post-hoc test for multiple comparisons among groups of RAE was conducted by Bonferroni adjustment [
37]. For one-way MANOVA, the results showed no significant difference in both children’s perceptions of PL and actual PL based on children’s relative age effect,
F(21, 911) = 1.37,
p = .12; Wilk’s Λ = .92, η
2partial = .03.
The effects of gender, RAE and their interactions on the perceived PL and children’s actual PL measured by CAPL-2 were examined using two-way MANOVAs respectively. Children’s actual PL showed a significant difference of gender using Wilk’s statistics trace, F(4, 316) = 7.67, p < .001, Wilks’ Λ = .91, η2partial = .09. No significant interaction effect was found, F(12, 836) = 1.19, p = .29, Wilks’ Λ = .96, η2partial = .02. The follow-up univariate ANOVAs revealed that the boys’ score was significantly higher than that of their female counterparts on Daily Behavior, F(1, 319) = 30.15, p < .001, Wilks’ Λ = 540.88, η2partial = .09. No significant gender differences were found in Knowledge and Understanding (p = .40), Motivation and Confidence (p = .32), and Physical Competence (p = .36).
For the perceived PL, using Wilk’s statistics trace, no significant gender differences were found on children’s perceptions, F(3, 317) = 1.60, p = .19, Wilks’ Λ = .99, η2partial = .02; and no significant interaction effect was found, F(9, 772) = .47, p = .90, Wilks’ Λ = .99, η2partial = .004. Boys scored slightly higher in all the attributes than girls but no significant differences were shown. Girls only acquired a higher score on Knowledge and Understanding in Q2 (M = 12.31) compared to boys (M = 12.31), and Self-expression and Communication with others in Q1 (M = 12.24) compared with boys (M = 12.22).
Discussion
This study was the first to explore the associations between the perceived and actual level of PL among Chinese primary school children and to examine the possible gender and relative age differences among those children. The results revealed that there were significant relationships between children’s perceived and actual level of PL in Chinese primary school children. Gender differences on actual PL, especially on the Daily Behavior domain of actual PL among Chinese children, were also observed. However, significant differences were not found on RAE in all the variables of this studied population. No interaction effect (gender x relative age effect) was found in all the associations among children.
Notwithstanding no previous studies for exploring the relationship between perceived and objectively measured PL, the results from the current study provides empirical evidence that the two perspectives have inter-related and significant associations. While similar studies in a related field have offered a number of evidence-based or theoretical explanations, they have assumed that children’s perceptions of their abilities closely approximate their actual skill competence [
38] and a few studies have found significant relationships between perceived and actual fundamental movement skills [
39,
40], and objective and subjective-measured physical activity [
41], etc. As an integrated concept emphasizing the embodiment that encompasses “the motivation, confidence, physical competence, knowledge and understanding” as factors for engagement in physical activity, perceived and actual levels of PL theoretically, and indeed empirically, have proven to be significantly associated. Furthermore, the results indicate the importance of considering an individual’s perceptions of PL when assessing his/her actual PL level [
2].
While perceived PL is feasible and practical to assess in a normal school environment, the significant associations between the perceived PL and actual levels of PL can provide a different angle for measuring students’ PL level. Given that children’s perceptions can directly reflect their actual PL level based on the assumed interpretation, Perceived Physical Literacy Instrument (PPLI) would be a more convenient tool to use in the educational environment [
17,
18]. Currently, PPLI has already been adopted in Hong Kong secondary schools to examine the effect of teaching intervention on adolescents’ PL and learning outcomes [
2]. Other evidence has also proved that perceived PL is positively associated with adolescents’ physical activity levels, especially within recreational physical activity [
20]. According to Whitehead, the philosophical foundations of the concept of PL concerning monism and embodiment support the belief that the body and mind are one and cannot be separated [
4,
21]. PL refers to the interconnected and inseparable nature of all the capabilities, that is, thoughts, feelings, and movements are intricately correlated [
21]. This partly explains that the PL perceptions of an individual’s psychological domain have unified inseparably with the actual PL level, or their actual physical activity patterns [
20].
The present study has also investigated gender differences, relative age bias, and their interaction effect on each dimension of perceived and actual levels of PL. Although the results only show that gender differences exist in the Daily Behavior domain of actual PL, they are consistent with previous studies that have found that boys score slightly higher than girls in most domains of CAPL-2 tests [
11,
42]. Although the manual recommended pedometers for measuring children’s step counts objectively, the current studies have adopted ActiGraph GT3X+ accelerometers for step evaluation [
31]. One of the main reasons for choosing this device is because it can measure various intensity of physical activity during a seven interval, and not focusing only on steps [
43]. Moreover, research has indicated that the accuracy of ActiGraph GT3X+ accelerometers can be granted due to set instrument sensitivity thresholds and/or attachment compared to pedometers [
44]. Therefore, the significant low level of Daily Behavior score in this study may result from the different devices used in monitoring step counts. Research related to gender differences in physical activity also provided evidence that boys are more active than girls in relation to step counts, MVPA and overall physical activity [
45‐
47]. It is informative that there are gender differences in each domain of the objectively measured PL, and to consider encouraging girls’ participation in more activities, as they showed a relatively less active lifestyle during their earlier years [
48].
Although a number of studies have found that RAE bias exists in elite-level athletes’ development [
28] and motor abilities in youth population [
49], relative age differences are not observed significantly in the perceived or actual levels of PL. These findings appear to be similar with a previous study exploring RAE bias on Canadian children’s objective PL. The study conducted by Dutil et al. [
29] has concluded that RAE bias is negligible among all the domains and overall PL levels. In assessing objective PL, the performance of children born in the months preceding the school entry cut-off date were not influenced by the relative age difference compared with their counterparts born later in the same year [
29]. However, a previous study has found that the RAE bias will influence the results of anthropometric measurements in children. However, this difference does not appear to have much influence on the actual PL levels as proven by the scholars [
29]. The research that has focused on relative age differences is relatively little and previous studies have suggested that the RAE is not regarded as an important factor when monitoring actual PL level of children with CAPL-2 [
27,
29].
For the perceived level of PL, no significant results of gender or RAE differences are found in the attributes of perceived PL. However, boys perceive more PL than girls in all the attributes, which is also consistent with previous studies [
19,
20]. The findings are expected, as previous research has shown that girls tend to participate less in physical activity [
42,
50], and with older age groups preferring non-physical activity-based pursuits that will influence their perceptions of PL imperceptibly. Researchers are challenged with exploring how to motivate children to move and to match their perceived ability in pursuing a physically active lifestyle [
42]. Therefore, the study has particularly drawn attention on the important role that perceived PL plays in the current challengeable environment in which children, especially females, are becoming less active. Although complicated, the concept of PL and the perceived ability of acknowledging PL highlight that the associations between the actual and perceived levels of PL should be highly valued for maintaining a physically active lifestyle [
4].
Despite valuable strengths being mentioned above for perceived and actual PL, the study is not without its limitations. First, the instrument of PPLI primarily does not include the dimension of perceived competency although PPLI is credited as a reliable measurement for assessing perceived PL. Concluding from the current study, perceived PL is still in the development stage and few studies have reported the association between PL perceptions with physical activity [
20]. This study serves as a pioneer to explore the possible relationship between children’s actual PL and perceptions to acquire a broader understanding of PL. The suggestions for exploring a comprehensive and streamlined instrument for assessing perceived PL should be particularly considered for further research on perceived PL. For example, perceived motor competence has been well assessed through a pictorial format of a self-perception profile of children identical to actual movement skills objectively measured [
39,
51]. However, unlike movement skills, PL is an abstract conceptualized construct that compasses a wide variety of dimensions. A more specific instrument for assessing perceived PL is not easy to develop, yet such aninstrument is urgently needed for acquiring a boarder understanding of PL.
As a battery of standardized assessment protocols to measure actual PL objectively, CAPL-2 is regarded to be valid and reliable to assess children’s actual level of PL. Notably, the comprehensive assessments include self-perceived measures in the Knowledge and Understanding domain and Motivation and Confidence domain of CAPL-2. However, the multidimensional concept of PL requires an objective assessment that encompasses and combines multiple components of PL, part of which cannot be directly measured, such as motivation, confidence, knowledge and understanding [
6,
13,
30]. Edwards et al. have also argued that measuring PL needs to combine all parameters of PL with qualitative and quantitative methods [
10]. The suggestions seem inspiring only from an idealist perspective, rather than in a practical school environment. A number of studies have reported that PE teachers intend to leave their profession due to high workload and scarcity of resources, especially in fast-paced cities like Hong Kong and Shenzhen [
52‐
54]. As some of the measures have already been adopted by PE teachers in schools (such as PACER, Plank), CAPL-2 improves with its second edition to provide a streamlined and convenient assessment battery for PE teachers to use without adding an extra burden. Using CAPL-2 for monitoring the actual level of PL for the current study is a compromise and takes the above factors into consideration.
Last but not least, the present study is designed as a cross-sectional study and only collected data at a specific time point. The design may cause insufficient evidence or causal inferences for testing the associations among variables. Also, it is possible that participant’s economic background, cognitive and emotional development would influence participants’ self-reporting. However, these were not measured in this study and should be taken into account in the design of future studies [
55].
