Perceived physical literacy instrument for adolescents: A further validation of PPLI.

ABSTRACT:

Background/objective

The purpose of this study is to examine the reliability and validity of "Perceived Physical Literacy Instrument" (PPLI) questionnaire in adolescents.

Methods

Based on physical literacy literature, a 9-item instrument was developed for initial tests. The self-report measure was administered to 1945 adolescents in Hong Kong. Confirmatory factor analysis (CFA) was used to examine a three-factor structure of physical literacy. A chi-square difference test analysed several competing models and compared the results between the proposed models (i.e., a three-factor solution) and other alternative models (i.e., a one-factor or two-factor solution). Furthermore, the measurement invariance across gender groups was examined by using multiple-group confirmatory factor analysis. Mean scores for physical literacy factors were also examined by demographic characteristics.

Results

Confirmatory factor analysis (CFA) showed that the construct demonstrated a good fit to the model. For convergent validity, our results, evaluating the factor loading of each items, the values of composite reliability (CR) and the average variance extracted (AVE) of the three factors, revealed that the three-factor validity of physical literacy was satisfactory. The chi-square difference test between models was significant indicating that all the latent variables had satisfactory discriminant validity. Moreover, the findings of measurement invariance showed that the PPLI is invariant across gender.

Conclusions

The PPLI thus appeared to be reliable and valid as a measure of the perceived physical literacy of adolescents. Thus, along with other validated instruments, protocols and research designs, the PPLI could be widely used to test adolescents' self-perception of physical literacy and their own physical and mental health conditions and thereby health. Physical education professionals may thus recommend appropriate intervention programmes for younger generations.

Project description:BACKGROUND:Health literacy is the ability to access to, understand, evaluate and use of essential health information to make basic health decisions. This study aimed to develop and psychometrically evaluate an instrument for measuring health literacy among adults (the Health Literacy Instrument for Adults - HELIA). METHODS:In addition to a literature review, a panel of specialists from different disciplines was formed to generate an item pool. Then, a framework was defined to develop the initial questionnaire based on a definition of health literacy and the most important global public health issues. The initial questionnaire contained 66 items. Next, 15 experts in public health were approached to assess content validity. Consequently, 19 items were removed and a provisional version of the questionnaire with 47 items was provided. Finally, a random sample of adults completed the questionnaire and psychometric properties of the instrument were assessed. RESULTS:Overall, 323 adults aged 18 to 65?years old completed the questionnaire. When the exploratory factor analysis was performed, 33 items were loaded, which indicated a 5-factor solution for the questionnaire that jointly explained 52.9% of the variance observed. The factors were as follows: access to information (6 items), reading (4 items), understanding (7 items), appraisal (4 items), and decision making/behavioral intention (12 items). Confirmatory factory analysis also indicated a good fit to the data for the five-latent structure (?2/df?=?1.60, SRMR?=?0.049; RMSEA?=?0.043; CFI?=?0.98; NFI?=?0.95; NNFI?=?0.98 and GFI?=?0.87). Additional analysis for internal consistency showed satisfactory results with Cronbach's alpha coefficients ranging from 0.72 to 0.89. Intraclass correlation coefficient (test-retest analysis) also showed acceptable stability for the questionnaire (ICC?=?0.84). The mean score for health literacy as measured by the HELIA was 76.3 (SD?=?15.1) out of 100 for the study sample. CONCLUSION:The findings suggest that the Health Literacy Instrument for Adults (HELIA) is a valid and reliable instrument for measuring health literacy. It is a short and easy-to-use instrument that could be applied in different settings.

Project description:BACKGROUND:The concept of physical literacy (PL) is gaining popularity within public health and physical education circles. However, little is known about the relationship between perceived and actual PL levels among school-aged children. The aim of this study is to explore the associations between perceived and actual levels of PL of primary school students in China. METHODS:A total of 327 children (153 boys and 174 girls) with a mean (SD) age of 10.0 (±1.0) years were included for analysis. PL perceptions were measured using the Perceived Physical Literacy Instrument. Children's actual level of PL was objectively assessed by the Chinese version of the Canadian Assessment of Physical Literacy, 2nd edition, which consists of four domains: Daily Behavior, Physical Competence, Motivation and Confidence, and Knowledge and Understanding. Pearson's correlation coefficients were calculated to examine the relationship between students' perceived and actual PL levels, whereas Multivariate Analysis of Variance (MANOVA) was calculated to investigate the gender, relative age differences, and interaction effect (2?×?4) on perceived and actual PL levels respectively. RESULTS:Significant correlations were observed between the perceptions and actual PL scores in both boys (r?=?.46, p?<?.01) and girls (r?=?.41, p?<?.01). Low to moderate significances were shown between each domain of perceived PL and actual PL (from .16 to .49). Further MANOVA results revealed that there were significant gender differences in the Daily Behavior domain of actual PL (F (1, 319)?=?30.15, p?<?.001, Wilks' ??=?540.88, ?2partial?=?.09). Overall, boys had both higher actual PL scores (58.9) and PL perceptions (37.3) than girls. Neither relative age effect nor interaction effect (2?×?4) was observed for the current participants in all the variables. CONCLUSIONS:This study is the first to examine the associations between the perceived and actual levels of PL in Chinese children. Additional studies should explore the importance of children's perceptions of PL when assessing the actual level of PL in physical education and health settings. Girls should be more encouraged by PE teachers to participate actively in physical activities in the school environment.

Project description:BackgroundThe Portuguese Physical Literacy Assessment (PPLA) is a novel tool to assess high-school students' (grade 10-12; 15-18 years) Physical Literacy (PL) in Physical Education (PE); inspired by the four domains of the Australian Physical Literacy Framework (APLF), and the Portuguese PE syllabus. This paper describes the development, content validation, and pilot testing of the PPLA-Questionnaire (PPLA-Q), one of two instruments in the PPLA, comprised of modules to assess the psychological, social, and part of the cognitive domain of PL.MethodsDevelopment was supported by previous work, analysis of the APLF, and literature review. We iteratively gathered evidence on content validity through two rounds of qualitative and quantitative expert validation (n = 11); three rounds of cognitive interviews with high-school students (n = 12); and multiple instances of expert advisor input. A pilot study in two grade 10 classes (n = 41) assessed feasibility, preliminary reliability, item difficulty and discrimination.ResultsInitial versions of the PPLA-Q gathered evidence in favor of adequate content validity at item level: most items had an Item-Content Validity Index ≥.78 and Cohen's κ ≥ .76. At module-level, S-CVI/Ave and UA were .87/.60, .98/.93 and .96/.84 for the cognitive, psychological, and social modules, respectively. Through the pilot study, we found evidence for feasibility, preliminary subscale and item reliability, difficulty, and discrimination. Items were reviewed through qualitative methods until saturation. Current PPLA-Q consists of 3 modules: cognitive (knowledge test with 10 items), psychological (46 Likert-type items) and social (43 Likert-type items).ConclusionResults of this study provide evidence for content validity, feasibility within PE setting and preliminary reliability of the PPLA-Q as an instrument to assess the psychological, social, and part of the cognitive domain of PL in grade 10 to 12 adolescents. Further validation and development are needed to establish construct validity and reliability, and study PPLA-Q's integration with the PPLA-Observation (an instrument in development to assess the remaining domains of PL) within the PPLA framework.

Project description:OBJECTIVE(S):The newly developed Low Physical Activity Questionnaire (LoPAQ) was designed to capture the low activity level among typically sedentary patients undergoing dialysis and correlated well with a physical activity questionnaire used in the general population. However, this instrument has not been validated against a more objective measure. METHODS:We recruited patients receiving dialysis for ?3 months from 3 dialysis facilities in San Francisco. Spontaneous walking activity was measured by pedometers over 7 days including a weekend and used as the standard reference. Patients were instructed to record their activities and step count readings. Study coordinators administered the LoPAQ during a dialysis session (hemodialysis [HD]) or clinic visit (peritoneal dialysis [PD]). The LoPAQ ascertains time and energy expended in walking activity, as well as light, moderate, and vigorous activity, and total physical activity during a 1-week recall period with 11 simple questions and requires approximately 10 minutes to administer. The LoPAQ also asks about time spent in sitting activities over 1 week. Spearman correlation was used to determine whether the LoPAQ results correlate with step counts. RESULTS:Sixty dialysis patients (HD = 48, PD = 12) completed the LoPAQ and wore a pedometer for 1 week. Mean age was 58.0 ± 12.7 years, 78.3% were men, and median dialysis vintage was 3.1 (IQR, 1.1-5.8) years. Median step count was 2,630.5 (1,270.7-5,137) steps/day. Most patients (82.8%) reported walking activity around the neighborhood, for transportation, and/or for fitness or pleasure, with a median of 595 (70-1,566.3) kcal/week. Total kilocalories per week of physical activity reported on the LoPAQ were 655 (422.8-2,336.8). Participants reported an average of 5 (3-8) sedentary hours per day. Energy expenditure in walking by the LoPAQ was highly correlated with weekly step counts (rho = 0.53, P < .001). In addition, the overall activity reported on the LoPAQ correlated with weekly pedometer readings (rho = 0.35, P = .01) and did not differ between HD and PD patients. CONCLUSIONS:The LoPAQ was easier and less time-consuming than previously validated physical activity questionnaires. LoPAQ demonstrated a good correlation with objective pedometer step counts among dialysis patients, similar to other physical activity instruments used in healthier and more active populations.
