Physical Activity Parenting Measurement and Research: Challenges, Explanations, and Solutions

Physical activity (PA) parenting research has proliferated over the past decade, with findings verifying the influential role that parents play in childrens emerging PA behaviors. This knowledge, however, has not translated into effective family-based PA interventions. During a preconference workshop to the 2012 International Society for Behavioral Nutrition and Physical Activity annual meeting, a PA parenting workgroup met to: (1) Discuss challenges in PA parenting research that may limit its translation, (2) identify explanations or reasons for such challenges, and (3) recommend strategies for future research. Challenges discussed by the workgroup included a proliferation of disconnected and inconsistently measured constructs, a limited understanding of the dimensions of PA parenting, and a narrow conceptualization of hypothesized moderators of the relationship between PA parenting and child PA. Potential reasons for such challenges emphasized by the group included a disinclination to employ theory when developing measures and examining predictors and outcomes of PA parenting as well as a lack of agreed-upon measurement standards. Suggested solutions focused on the need to link PA parenting research with general parenting research, define and adopt rigorous standards of measurement, and identify new methods to assess PA parenting. As an initial step toward implementing these recommendations, the workgroup developed a conceptual model that: (1) Integrates parenting dimensions from the general parenting literature into the conceptualization of PA parenting, (2) draws on behavioral and developmental theory, and (3) emphasizes areas which have been neglected to date including precursors to PA parenting and effect modifiers.

Effects of an Exercise Programme on Anxiety in Adults with Intellectual Disabilities.

Although high anxiety is common in people with intellectual disabilities (ID) and the anxiolytic effects of exercise have been systematically recognised in clinical and non-clinical populations, research is scant concerning the role played by exercise on anxiety in people with ID. The purpose of this study was to investigate the effects of a 12-week exercise programme on anxiety states in a group of adults with ID. Twenty-seven individuals with mild to moderate ID were randomly assigned to an exercise group or a control group. The Zung Self-Rating Anxiety Scale adapted for individuals with ID and the State-Trait Anxiety Inventory form Y were used to assess trait and state anxiety. In comparison with the control group, the anxiety scores of people in the exercise group decreased significantly over time.

Exercise intervention to reduce depressive symptoms in adults with intellectual disabilities.

People with intellectual disabilities are often reported as having depressive symptoms. Although the antidepressant effect of exercise has been systematically recognized, research concerning the role of exercise on depressive symptoms in people with intellectual disabilities is still scant. A 12-wk. exercise intervention for depressive symptoms in a group of adults with intellectual disabilities was conducted. Participants were 16 men and 11 women, randomly assigned to an exercise group (n = 14) or to a control group (n = 13). The Zung Self-Rating Depression Scale adapted for people with intellectual disabilities was administered at baseline, after 6 wk. and at the end of the intervention. There were statistically significant reductions in scores for the exercise group compared with the control group. Results support the notion that exercise can improve well-being in people with intellectual disabilities.

Physical activity practice, body image and visual impairment: A comparison between Brazilian and Italian children and adolescents

The aim of this study was to analyze the physical activity and body image of children and adolescents with visual impairment (VI) in Brazil and Italy. For this, 41 children and adolescents with VI (19 Brazilian and 22 Italian) aged 10.22 ± 2.19 years old (18 girls and 23 boys) answered the Physical Activity Questionnaire for Children (PAQ-C), the Offer Self-Image Questionnaire (OSIQ), and an instrument with information about the disability, body weight and height. We analyzed the relationship between data from PAQ-C and OSIQ, as well as the gender, level of disability (blindness or low vision) and country using independent Mann-Whitney test. Body mass index (BMI) values were higher for Brazilian youths, with more than half of them classified as overweight and obese. Italian youths exhibited values of body image that were more positive and only 27% presented overweight or obesity. Blind children and adolescents were less active than those with low vision, but no differences were found between countries or genders. In Brazil, we detected significant correlations (p>0.05) between physical activity, body image and BMI, which more active youths presenting lower values of BMI and a better perception of body image. Physical activity seems to have a positive influence on body image and BMI for children and adolescents with VI, thus it should be encouraged especially for those with higher disability degrees.

Peer-victimization during physical education and enjoyment of physical activity.

This study examined the relations between peer-victimization during sport practice and physical activity enjoyment. 395 students (219 boys, 176 girls) from a middle school, ages 12 to 13 years (M = 12.2), were surveyed. Few correlations between peer-victimization during sport practice and physical activity enjoyment variables were negative. Linear regression analysis was also conducted, highlighting a subtle influence of peer-victimization during practice of sports on enjoyment of physical activity. Peer-victimization during practice of sports seems to be a poor predictor of low enjoyment of physical activity.

Formação de professores para a educação especial: uma discussão sobre os modelos brasileiro e italiano

As public policies advance in the direction of mass producing inclusion of special educational needs students in regular schools, discussions have emerged about changes that are required in teacher preparation to meet this new demand. The aim of this study was to discuss Brazilian and Italian models of teacher preparation for those working in special education. To this end, we conducted a documentary study, analyzing legal texts related to the topic from both countries. Italy was the first country in Europe to promote the end of special schools and the inclusion of all students with disabilities in regular schools. Furthermore, in this country there are clear government guidelines regarding teacher preparation to work with students with special educational needs. On the other hand in Brazil, despite the great advances regarding public policies that support teacher preparation, specific parameters on the minimum content necessary for providing teachers with the subsidies they need to promote quality inclusion are still lacking.

A contribution to the validation of the Wii Balance Board for the assessment of standing balance

Abstract Valid and reliable accessible measures of balance are required in a health-related fitness test battery, both in the general population and in groups with special needs. For this purpose, the capability of the Wii Balance Board (WBB) in evaluating standing balance was analysed and compared with a laboratory-graded force platform (FP). A 30-s double limb standing test with open and closed eyes was performed by 28 individuals (12 male and 16 female, mean age = 23.8, SD = ±2.7 years). A simple method of acquisition of the centre of pressure (CoP) over time was applied to compare WBB and FP simultaneously on the same signal. User-defined software was developed to obtain the CoP from WBB over time and the resulting related measures and graphical representations. The comparison of measures, such as sway path and maximum oscillations along the anterior–posterior and medial–lateral direction, obtained with the FP and the WBB shows that the latter, in conjunction with the user-defined developed software, can be appropriate, considering prescribed limits, and an easy-to-use tool for evaluating standing balance.

Physical activity practice among children and adolescents with visual impairment – influence of parental support and perceived barriers

Abstract Purpose: To analyze the practice of physical activity among children and adolescents with visual impairments (VI), regarding the possible influence of parental support and perceived barriers. Methods: Twenty-two young people with VIs (10 + 2.74 years old) and one of each of their parents were evaluated. They responded to the Physical Activity Questionnaire for Older Children (PAQ-C), Baecke Questionnaire, the Parental Support Scale and a questionnaire about perceived barriers to physical activity. The independent samples t-test, pearson correlation test and chi-square test were performed. Results: Blind young people showed lower physical activity levels. There were significant correlations both between parents’ physical activity and the support offered to children and between the PAQ-C results and the importance given by young people to physical activity, but only for those aged between 8 and 10 years old. The main perceived barriers were lack of security, motivation, professional training and information about available physical activity programs. Conclusion: The influence of parental support seems to be an important factor in the adoption of a physically active lifestyle for young people with VI. Parents and children should have more information about the benefits and opportunities of physical activity. Implications for Rehabilitation Young people with visual impairment should be encouraged by parents to practice physical activity. More information should be provided on the benefits of physical activity to both parents and children. Professional training should be available to help support this group become more active.

Enjoyment Perception during Exercise with Aerobic Machines

This study investigated enjoyment and naturalness of movement perceived during short bouts of exercise with three aerobic machines: treadmill, elliptical crosstrainer, and Vario. The participants were 72 experienced and 60 inexperienced users. Immediately after the exercise with each machine, they filled in a 12-item form of the Physical Activity Enjoyment Scale (PACES) and a Visual Analogue Scales (VAS) about naturalness of movement. Results showed significant within-subjects differences on all scales; exercise with the treadmill and Vario were perceived to be similarly enjoyable and more enjoyable and natural in comparison with the elliptical crosstrainer. Differences in naturalness ratings between experienced and inexperienced users were observed. Exercise was not equally enjoyable when performed with different aerobic machines, and this should be considered by professionals when prescribing aerobic training to enhance motivation and adherence.

Psychometric Properties of the Physical Activity Questionnaire for Older Children in Italy: Testing the Validity among a General and Clinical Pediatric Population

The purpose of this research was to assess an Italian version of the Physical Activity Questionnaire for Older Children (PAQ-C-It). Three separate studies were conducted, whereby testing general psychometric properties, construct validity, concurrent validity and the factor structure of the PAQ-C-It among general and clinical pediatric population. Study 1 (n = 1170) examined the psychometric properties, internal consistency, factor structure (exploratory factor analysis, EFA) and construct validity with enjoyment perception during physical activity. Study 2 (n = 59) reported on reliability, construct validity with enjoyment and BMI, and on cross-sectional concurrent validity with objectively measured MVPA (tri-axial accelerometry) over the span of seven consecutive days. Study 3 (n = 58) examined the PAQ-C-It reliability, construct validity with BMI and VO2max as the objective measurement among a population of children with congenital heart defects (CHD). In study 2 and 3, the factor structure of the PAQ-C-It was then re-examined with an EFA. The PAQ-C-It showed acceptable to good reliability (alpha .70 to .83). Results on construct validity showed moderate but significant association with enjoyment perception (r = .30 and .36), with BMI (r = -.30 and -.79 for CHD simple form), and with the VO2max (r = .55 for CHD simple form). Significant concurrent validity with the objectively measured MVPA was reported (rho = .30, p < .05). Findings of the EFA suggested a two-factor structure for the PAQ-C-It, with items 2, 3, and 4 contributing little to the total score. This study supports the PAQ-C-It as an appropriate instrument to assess the MVPA levels of Italian children, including children with simple forms of CHD. Support is given to the possible instrument effectiveness on a large international perspective in order to level out data gathering across the globe.
