- List examples of and explain what is meant by the subjective & objective measures of PA?
Subjective measures: assessments of physical activity that rely on a person remembering which activities they participated in, or their perception of the intensity of an activity session. E.g. Self-report measures – completed by subjects, involve some bias, include both self-administered and interviewer-administered recalls through interviews, questionnaires, diaries or logs. E.g. Proxy-report measures – involve an individual reporting on behalf of someone else.
Objective measures: physical activity assessments using either direct observation or a device. Direct observation – involves watching people’s behaviours within specific settings and recording activities and events of interest. E.g. pedometer – observing how many steps an individual has taken throughout the day or week, Garmin, Fitness Watch
- What sort of tools are used to assess the population and record PA across different settings?
The Children’s Leisure Activities Study Survey (CLASS): a self-report for children over 10 years and a proxy-report questionnaire completed by parents for children 10 years and under. It assesses all dimensions of physical activity (including type, frequency, intensity and duration) performed during a typical week of a school term.
Subjective and objective measures – self-report, proxy-report, pedometers, diaries
- What are the most common PA participated in for Adults, Children and the elderly?
Adults: walking, going to the gym, jogging, swimming and cycling
Children: swimming, soccer, cycling, athletics/track and field, basketball, dancing, cricket, netball
Elderly: water aerobics, walking, golf, lawn bowls
- What proportion of Australians are very inactive or complete no PA?
1 in 5 Australian adults exercise at very low levels, or not at all.
- What is meant by the term self-efficacy and give an example?
Self-efficacy: confidence in your ability to be active within specific circumstances
e.g. even when you are tired,
- What is the most common barrier towards participation in PA?
- Lack of time
- Define with an example reciprocal causation
Reciprocal causation: the interaction between the individual and the environment.
e.g. if you live near the ocean then you are more likely to surf.
- When is a proxy report best suited for which demographic of the population?
Proxy reports are completed for someone who is unable to self-report in a reliable and accurate (valid) manner.
May be completed for a child by a parent, guardian or teacher. A carer may complete a proxy report on behalf of an elderly person or a person with an intellectual disability.
- What is the name of a method to target a change in policy, environment or organisation?
Intervention strategy: method or approach to target a change in policy, environment or organisation.
- List examples of population-level strategies that promote PA.
Environmental strategies and tailoring:
Physical activity intervention programs should be tailored to settings.
e.g. installing bicycle racks may promote cycling to school in a rural area, but may be impractical in a suburban are with limited bike paths and heavy traffic.
- Removing impediments to activity: remove barriers to people being active, e.g. heavy traffic and ‘stranger danger’ or other street crime. Environmental changes, such as the installation of speed humps and reduced speed limits near school zones, can significantly reduce the volume and speed of the traffic, increasing safety for pedestrians and cyclist.
- Introducing new resources and facilities: other environmental interventions aim to provide resources that facilitate activity, such as:
• Installing showers in the workplace
• Providing footpaths and bike trails in the community
• Installing a new or upgraded playground in a local park or school
Education programs: environmental interventions should precede education programs. E.g. a media campaign encouraging people to walk in their neighbourhood will not have much impact in an area where footpaths are poorly maintained and drug deals take place in the park. Instead of a media campaign, the priority in this neighbourhood would be to reduce crime and provide a safe recreational environment for people to be active in. Only then can an educational program successfully encourage people to walk in their neighbourhood.
Environmental and policy targets for physical activity interventions: natural environment (e.g. weather, geography), constructed (built) environment factors (e.g. information environment, suburban environments, buildings, work environments, entertainment infrastructure, transport infrastructure, recreational infrastructure), policies related to incentives, policies related to resources and infrastructure.
Policy: may be defined as laws, regulations, formal rules, informal rules or understandings that are adopted on a collective basis to guide individual and population-wide behaviour. There are many policies that affect people’s opportunity’s to be physically active; these policies can act as either enablers or barriers.
- Legislation: refers to formal, documented policies that are often governed by law-enforcement agencies and organisations. E.g. having to wear a seatbelt.
- Organisational policies: designed to establish an appropriate behaviour within a particular organisation. E.g. many primary schools have a SunSmart policy that prevents children playing outside unless they are wearing a hat. When you critique strategies used at the population level to promote physical activity think about: tailoring, removal of impediments, resources and facilities, educational programs and policies to support environmental change.
Mass media: aim to reach groups of individuals using a medium other than personal
contact or face-to-face meetings. E.g. online advertising, pop-ups, social media, websites, television and radio broadcast and advertisements, billboards, posters and commercials at cinemas, print media such as newspapers, magazines and brochures, web-based interactive information. Main benefit is the potential to reach large numbers of people at a lower cost per person than individual approaches, raise awareness and increase motivation.
- The roles of mass media: increasing awareness of physical activity as a public health issue, providing information about the health benefits associated with regular physical activity, providing information about other non-health benefits of being active, providing information about the consequences of inactivity.
- List examples of individual level strategies that promote PA.
Print and web-based media: include booklets, brochures, handouts and websites. Print materials are available from: community-based recreational centres (e.g. sporting clubs), healthcare providers such as medical practices, rehabilitation centres (e.g. physiotherapy), hospitals and chemists, schools and workplaces, government, industry and commercial websites.
Counselling: gives advice about being physically active can be provided by a personal trainer, general practitioner (GP).
- Which are the best measurement tools used to record the amount of sedentary behaviour that a person undertakes?
- Diaries
- Accelerometers
- Self- or proxy-report recall surveys
- Direct observation
- Inclinometers
- What are the advantages and disadvantages of both objective & subjective measures of assessment of PA. eg. Pedometers vs recall surveys vs SOPLAY etc
Advantage subjective:
- Can capture quantitative and qualitative information
- Can be administrated for large- scale studies
- Usually low burden on participants
Disadvantage subjective:
- Not suitable for assessing children under age 10 or very old adults
- Reliability and validity problems associated with over- reporting due to social desirability bias, memory limitations or misinterpretations of physical activity in different populations
Positive objective:
- Captures excellent quantitative and qualitative information
- Computer software makes data collection and analysis simpler than in the past
- Not subject to bias
- Pedometers
- Inexpensive
- Non- invasive
- Easy to administer to large groups
Negative objective:
- Possibility to tamper with results
- Some accuracy loss
- SOPLAY
- Measures physical activity in groups of people
- Uses time- sampling techniques
- Scans individual and contextual factors
- Name some social environment strategies that can be implemented in schools, the workplace and the community.
- Walking paths – walk to school day, ride to work.
- Know statistical trends for participation in PA by gender over the years ie 15-17’s - 65+ for both genders.
2-4 years old:
- Averaged 6.2 hours per day in pa
- 47% of pa form outside activities
- QLD and NT spent more time outdoors (3 hours 27 minutes and 4 hours respectively, compared to the national average of 3 hours)
- 72% were physically active for 3 hours per day on all 7 days prior to interview, therefore meeting the pa guidelines.
5-17 year olds:
- Averaged 1.5 hours (91 minutes) per day in pa.
- Just over 60% averaged at least 60 minutes per day
- 1 in 5 (19%) doing recommended 60 minutes per day across all 7 days prior to interview
- Almost half (48%) met the recommended 60 minutes per day on at least 5 out of the 7 days
18+ year olds:
- Averaged 33 minutes per day of pa
- 60% reported doing less than 30 minutes
- Fewer than 20% did 60+ minutes per day on average
- 43% met the ‘sufficiently active’ target (59% males and 48% females)
- 18-24 year olds were the most active (males averaged 46 minutes and females 32 minutes per day)
- Levels generally declined with increasing age
- Only 33% of males and 20% of women over 75 years were sufficiently active.
