Physical Literacy – to be discussed: eine Perspektive aus Sicht der deutschsprachigen Sportwissenschaft

Development of the Perceived Physical Literacy Questionnaire (PPLQ) for the adult population

Background/objective

In physical literacy (PL) research, instruments for the adult population covering all relevant domians are currently lacking in German language. Therefore, the Perceived Physical Literacy Questionnaire (PPLQ) was developed as an assessment instrument of PL for the adult population. The purpose of this study is to describe the multistage development process leading to the aim to evaluate the psychometric properties of the PPLQ.

Methods

Based on established questionnaires (subscales) operationalizing the six defined PL domains (motivation, confidence, physical competence, knowledge, understanding, and physical activity behavior), we generated a large item pool. Exploratory analyses on survey data (n = 506), compelemented through an expert panel, served to identify the best fitting items. Cognitive interviews (n = 7) and a language certification process (level A2) helped to enhance the content validity of the items. Finally, we assessed the hypothesized factor structure of the PPLQ and its convergent validity with the Physical Activity-related Health Competence (PAHCO) questionnaire in a second independent sample.

Results

Valid data of 417 adults (66% women, 48 ± 16 years) entered the confirmatory factor analysis. We found empirical support for a theory-compatible 24-item version, after reducing complexity (i.e., domain subscales). Additionally, the six domains could be subsumed under an overall factor for PL (χ2247 = 450.70, χ2/df = 1.83, CFIRobust = 0.895, RMSEARobust = 0.074 [CI90 = 0.063-0.085], SRMR = 0.064). Factor loadings, composite reliability, and discriminant validity were sufficient, while acceptable convergent validity was achieved for the total PL score and three domains.

Conclusion

The 24-item version of the PPLQ is appropriate for assessing PL among adults. However, some items (especially in the knowledge domain) can benefit from refinement in further studies.

Development and evaluation of a school-based physical literacy intervention for children in Germany: protocol of the PLACE study

Introduction

Fueled by the COVID-19 pandemic, the physical activity behavior of children has reached a concerning level nowadays. By empowering individuals to be physically active throughout the life course, the concept of physical literacy has recently gained increasing attention and adopts a holistic-integrative perspective on PA promotion. Although the field has successively attempted to translate the conceptual ideas of physical literacy into interventions, the theoretical base is heterogeneous and is often lacking within interventions. Furthermore, several countries, including Germany, have not equally adopted the concept yet. Therefore, the goal of the present study protocol is to describe the development and evaluation approach of a PL intervention ("PLACE") for children in grades three and four within the German all-day schooling system.

Methods

The physical literacy intervention cultivates explicit theory-content links and comprises 12 heterogeneous sessions (each 60-90 min in length). The study contains three different phases with two initial pilot studies and a subsequent main study. The two pilot studies take a mixed-methods character by drawing on quantitative pre-post-designs as well as interviews with children (in groups). In the main study, we will longitudinally compare the course of PL values (five outcome domains: physical, affective, cognitive, social, behavioral) between two study arms: school classes of children are either assigned to an intervention condition (regular physical education and health care plus PL intervention) or to a control condition (regular physical education and health care only).

Discussion

The findings of this study will provide evidence on how to structure a multicomponent intervention in Germany based on the PL concept. In summary, the results will report on the effectiveness of the intervention and, therefore, decide whether to scale-up the intervention.

Motivational readiness for physical activity and health literacy: results of a cross-sectional survey of the adult population in Germany

BACKGROUND

Health literacy, defined as the knowledge, motivation, and competences to use health information to improve health and well-being, is associated with regular physical activity. However, there is limited evidence on whether health literacy is also related to the motivational readiness for physical activity in a general population. The aim of this study was to investigate whether motivational readiness for leisure-time physical activity is associated with health literacy.

METHODS

Analyses were based on data of 21,895 adults from the cross-sectional German Health Update and European Health Interview Survey 2014/2015 (GEDA 2014/2015-EHIS). Motivational readiness for leisure-time physical activity was assessed with stages of change for physical activity with a set of validated items. It was then classified, according to an established algorithm, into five stages: precontemplation, contemplation, preparation, action, and maintenance. Health literacy was measured with the short form of the European Health Literacy Survey Questionnaire (HLS-EU-Q16) and categorised as low, medium, and high. For bivariate and multinomial logistic regression analyses, the stages were categorised in three phases as: (1) no intention (precontemplation), (2) planning (contemplation or preparation), and (3) in activity (action or maintenance). The models were adjusted for sex, age, education, health consciousness, self-efficacy, and self-perceived general health status.

RESULTS

High compared to low health literacy was associated with a 1.65-times (95% CI = 1.39-1.96) greater probability of being in activity than planning. High compared to low health literacy was associated with a reduced risk of having no intention to change physical activity behaviour (relative risk ratio, RRR = 0.84, 95% CI = 0.75-0.95). The associations persisted after adjusting for covariates.

CONCLUSION

High health literacy was positively associated with more advanced phases of motivational readiness for leisure-time physical activity. Therefore, taking health literacy into account in interventions to promote motivational readiness for leisure-time physical activity could be a useful approach.

Physical literacy in Europe: The current state of implementation in research, practice, and policy

Background/objective

The holistic concept of physical literacy (PL) embraces different person-centered qualities (physical, cognitive, affective/psychological) necessary to lead physically active lifestyles. PL has recently gained increasing attention globally and Europe is no exception. However, scientific endeavors summarizing the current state of PL in Europe are lacking. Therefore, the goal of this study was to comprehensively assess and compare the implementation of PL in research, policy, and practice across the continent.

Methods

We assembled a panel of experts representing 25 European countries. Employing a complementary mixed-methods design, the experts first prepared reviews about the current state of PL in their countries (categories: research, practice/policy). The reviews underwent comparative document analysis, ensuring a transnational four-eyes principle. For re-validation purposes, the representatives completed a quantitative survey with questions reflecting the inductive themes from the document analysis.

Results

The document analysis resulted in ten disjunct themes (related to "concept", "research", "practice/policy", "future/prospect") and yielded a heterogenous PL situation in Europe. The implementation state was strongly linked to conceptual discussions (e.g., existence of competing approaches), linguistic issues (e.g., translations), and country-specific traditions. Despite growing scholarly attention, PL hesitantly permeates practice and policy in most countries. Nevertheless, the experts largely anticipate increasing popularity of PL for the future.

Conclusion

Despite the heterogeneous situation across Europe, the analysis has uncovered similarities among the countries, such as the presence of established yet not identical concepts. Research should intensify academic activities (conceptual-linguistic elaborations, empirical work) before PL may gain further access into practical and political spheres in the long term.

The Effectiveness of Physical Literacy Interventions: A Systematic Review with Meta-Analysis

BACKGROUND

The holistic concept of physical literacy assumes that individuals require adequate cognitive (knowledge and understanding), affective (motivation and confidence), and physical (physical competence) qualities to engage in lifelong physical activity behavior. In recent years, the research field has undergone rapid development and has also yielded an increasing number of interventions that aim to translate the theoretical-philosophical ideas into practical endeavors.

OBJECTIVE

The goal of the present pre-registered systematic review was to (a) provide a general overview of evaluation studies on physical literacy interventions and (b) to quantitatively examine the effectiveness of physical literacy interventions.

METHODS

Drawing on the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched a total of 18 databases for physical literacy interventions. Inclusion criteria were English language, publication by November 2021, and interventions using physical literacy as a theoretical underpinning or evaluation outcome. Articles that met these criteria were analyzed with respect to their basic delivery characteristics, study quality, evaluation approach, and main findings. We additionally ran meta-analyses with all non-randomized and randomized controlled trials to examine and compare the effect of these interventions on five outcome categories: (i) physical competence, (ii) motivation and confidence, (iii) knowledge and understanding, (iv) physical activity behavior, and (v) total physical literacy. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated to assess the effects on the different categories.

RESULTS

The screening process with two independent raters yielded 48 eligible interventions reported in 51 eligible articles. Quantitative evaluations most frequently addressed physical competence (72.2%), followed by motivation and confidence (47.2%), physical activity behavior (41.7%), and knowledge and understanding (33.3%). The controlled intervention studies (n = 24) exerted significant effects on all five physical literacy categories. Despite meaningful heterogeneity across the subgroups, the strongest effects were found for physical competence (SMD 0.90; 95% CI 0.55-1.25), followed by physical literacy aggregate scores (SMD 0.61; 95% CI 0.20-1.01), knowledge and understanding (SMD 0.54; 95% CI 0.30-0.79), physical activity behavior (SMD 0.39; 95% CI 0.23-0.55), and motivation and confidence (SMD 0.30; 95% CI 0.17-0.44).

CONCLUSIONS

The present study empirically demonstrated the effectiveness of physical literacy interventions on several outcomes relevant for promoting physical activity and health. To better inform current practices, future studies are advised to identify those program characteristics that significantly influence the effectiveness of physical literacy interventions.
