Activity Monitors Flashcards
1
Q
Purpose of portable electronic heart rate meters?
A
Used to infer metabolic activity in free-living (vs. laboratory) subjects
2
Q
Fxn of pedometers
A
Count steps
3
Q
Where are pedometers worn
A
At hip or ankle
4
Q
Science behind pedometer
A
- low cost pedometers use simple mechanical switch
- when limb movement causes large enough perturbation of the monitor the switch closes momentarily and pedometer registers a step
5
Q
What are accelerometers
A
- piezoelectric crystals that have property of producing tiny voltage proportional to amount of strain on crystal
6
Q
3 things heart rate meters can measure?
A
- intensity of action
- metabolic rate
- caloric expenditure
7
Q
Characteristics of heart rate meters
A
small, light, minimally intrusive
8
Q
heart rate is a valid and reliable indicator for what in most cases?
A
exercise intensity
9
Q
What is reliability
A
Similar value obtained on repeat measures under similar conditions
10
Q
4 situations in which heart rate does not accurately reflect exercise intensity
A
- Arm work: HR overestimates intensity
- Prolonged exercise: HR drifts upward
- Medications: May limit HR increase
- Horizontal: HR lower for a given intensity compared w/upright posture
11
Q
3 subjects written about activity monitor discussed in textbook
A
- accuracy of monitors (special consideration is the quantification of activity among children and youth)
- use of activity monitors to see if an “intervention” makes people more active
- does giving people a pedometer result in an increase in their activity level
12
Q
When is inaccuracy of pedometers the greatest
A
at lower walking speeds or very fast walking/running
13
Q
4 steps to ensure pedometer counts steps accurately
A
- attach device at waistline, directly above kneecap
- don’t attach pedometer to loose garments like dresses
- regularly check pedometer while ur walking to make sure doesnt shift out of position
- unless otherwise instructed, wear pedometer in 1upright position
14
Q
Accuracy of pedometers varies with what factors
A
One’s walking speed, stride length, & force w/which one’s feet strikes the ground
15
Q
What pre check can be done to check accuracy of pedometer?
A
clip to waist or belt & check accuracy by counting ur steps as u walk ur normal walk, then compare steps w/what pedometer indicates
16
Q
Describe the sensitivity vs. specificity dilemma with pedometers
A
- how large a movement should be counted as a step?
- if sensitivity too low, some real steps overlooked
- if specificity too low, minor movements that aren’t “real” steps will be counted
17
Q
Advantages of using pedometer to assess daily or weekly activity patterns as a whole
A
- cheap
- objective
- does not interfere w/daily activities & is thus appropriate to use in population studies
18
Q
advantage of commercial accelerometer with time-sampling mechanism
A
could be used to provide a picture of the pattern of children’s activity
19
Q
if wanting to use pedometers to motivate people to become more active, what aspect is more important and less important?
A
- accuracy doesn’t matter
- reliability matters
20
Q
Example of indirect calorimetry
A
measurement of oxygen consumption
21
Q
Main finding of Couter et al. (2003) for pedometer study?
A
pedometers most accurate for counting steps, less accurate for assessing distance, and even less accurate for assessing kcal
22
Q
Main finding of Melanson et al. (2004) for pedometer study?
A
even at very slow speed of 1.0 mph, accuracy of piezoelectric pedometer while not good, was better than spring-levered pedometers
23
Q
Main findings of Crouter, Schneider & Basset for pedometer study?
A
- in overweight and obese individuals, piezoelectric pedometer more accurate than spring-levered pedometer esp at slower walking speeds
- pedometer tilt (more than waist circumference and BMI) most important factor influencing accuracy of spring-levered pedometer
- piezoelectric pedometer not affected by pedometer tilt, waist circumference, or BMI
24
Q
For Craig, Cameron, and Cragg study, avg # of steps reported was…
A
- less than that recommended to maintain healthy body mass

25
During Bruner et al. (2006) study involving youth, what did the results show
- inc in activity from oct to dec
- steady decline in each of the 3 subsequent periods
- greatest dec from feb to april
26
Why are children less likely to make accurate self-report assessment than adults
developmental differences, esp in ability to think abstractly and perform detailed recall
27
McMurray's study on MVPA for adolescence showed what
3 day recall period too long for accurate recall of MVPA info
- for both genders survey overestimates activity lvls
28
Problems with using heart rate telemetry to give estimates of daily activity in children
- heart rate indirect estimate of PA and makes assumptions based on linear relationship btwn heart rate & oxygen uptake
- heart rate sensitive to emotional stress, body position, takes longer to reach resting lvls after physical exertion compared w/o2 uptake
- lags behind movement (bad cause children's PA sporadic in nature)
29
What characteristics must instrument posses to accurate assess children's activity patterns
- must be sensitive enough to detect, code, or record sporadic & intermittent activity
30
Out of heart rate monitoring, pedometry, triaxial accelerometry, and uniaxial accelerometry, which was the best measure for estimating oxygen consumption during typical Welsh children's activities
triaxial accelerometry
31
Beets, Patton, & Edwards study accuracy of pedometers during self-paced walking and treadmill walking in children showed what
same pedometer inaccuracy at slower walking speeds as has been observed in adults
- time might be used in addition to steps to quantify the PA behaviour of children
32
Suggestions to improve assessments of PA in children with monitors?
- focus assessments on key times or places that allow children to be active
- monitoring of entire groups for discrete periods of time useful to understand variability in activity patterns since children would all be exposed to same stimulus or opportunity to be active
- proxy measures useful (e.g. time spent outside strongly predictive of activity in children)
- employ multiple measures of PA to provide more complete description of children's activity & permit a triangulation of outcomes
33

44
What is communication
a way to share info, to establish rapport, to emphasize
45
how do humans communicate
- with sophisticated verbal and symbolic (e.g. mathematical, computer) languages
- give & receive subtle and rich non-verbal msgs
- person on receiving end gives verbal and non-verbal signals
46
What comprises active listening
- with sophisticated verbal and symbolic (e.g. mathematical, computer) languages
- give & receive subtle and rich non-verbal msgs
- person on receiving end gives verbal and non-verbal signals
47
3 reasons why beginnings are important
1. They set the tone
2. They are an opportunity to establish rapport, thru display of genuineness, empathy, & warmth
3. They are a time to clarify expectations
48
4 open-ended questions counselors use that are effective
1. Why do you think that is?
2. What do you think might help?
3. Has this ever happened before?
4. What did you do about it then?
49
What are closed-ended questions
Those that can be answered briefly, usually with a single word like yes or no
- tend to stifle rather than encourage dialogue
50
why ask open ended questions instead of closed ended
to elicit lengthier answers
51
what to do when client wandered off topic or repeating herself
refocus session
| - "ok im getting good picture of how u spend ur weekends, how do u spend ur weekdays?"
52
what type of body language should you display when talking to client
- position urself close enough to client to be able to be converse in a normal voice (1-2 meters) while not invading personal space
- position urself so your eyes are at the same level of clients
- rest arms on legs or arm of chair, rest feet on floor
- make eye contact but don't stare
- turn body so generally faces client
53
in a good counselling session, how much talking does counsellor do
20%
54
4 skills of active listening, example of each
1. Bridging - use of little words like "yes, go on, I see"
- signal to speaker ur listening
2. Restating - repeating last word or few words of client
- "often i plan to run after work but i'm too tired. i'm usuall so organized idk whats wrong." "counsellor: what's wrong..?"
3. Paraphrasing - summarizing in own words what u heard
- ensure u understand what client thinking n feeling
- "it sounds as tho u r looking forward to brothers visit but concerned itll interfere w/ur workout sessions"
4. Asking for clarification - when ur not sure u've understood client
- "could you elaborate on that"
55
what is reactance
- counsellor wants to avoid causing client to "react"
- reactance presents in negative cognition like "I hate you"
- the reacting person perceives a threat to their freedom & respond by becoming defensive and stubborn
- reactance causes person to do more of the behaviour u r trying to get them to stop
- more likely in response to explicit, threatening language, or dogmatic, authoritarian, or domineering tone
- subject w/high reactance scores more prone to rxn than others
56
1st step when working w/new person or group is to? next steps?
1. establish rapport
- explore issues
- mobilize his/their resources
- develop self-efficacy
57
how does a group leader change over time in a group that starts to mature
- initially directive, as group develops confidence & self-efficacy and matures, an effective leader will back off and give inc responsibiity n autonomy to group
58
Characteristics of teaching
- plan but be flexible
- have a standard format, but use variety
- plan the session in 20-min 'chunks'. learning falls off dramatically as attention span wanes
- keep it simple
- more is not better
- first demonstrate, & then explain
- if the msg is complex, give it in writing
59
goal of counsellor?
support change
60
what should a counsellor do
- help client frame the problem "Why are u here? What would u like to happen?"
- help client explore the issue "what have u tried in the past"
- try to build self-efficacy
61
Process of active listening with client and counsellor
1. Develop rapport w/client
2. Create a comfortable environment
3. Establish a helping relationship

62
What is empathy
the capacity for participation in another's feelings or ideas
63
What is sympathy
the act or capacity of entering into or sharing the feelings or interests of another OR affinity, association, or relationship btwn persons or things wherein whatever affects one similarly affects the other
64

2. Director
3. Educator
4. Consultant
74
Who is a preacher
- urges client adopt healthy lifestyle
- tells client what to do, but not much about how to do it
- motivates people (maybe thru guilt) but imposes value judgments & prevents dialogue
75
Who is a director
- tells client what to do
- provides guidance & structure
- most appropriate at action stage
- most clients resent being told what to do
- under-uses client herself as a resource
76
Who is an educator
- delivers info in an objective, nonjudgmental & nondirective way
- efficient at covering lot of material in given time period
- reassuring for people familiar w/this style (students)
- intimidates other clients
- prevents dialogue
- info alone has disappointingly small effect on altering behaviour
77
Who is a counsellor
- works w/client & involves them actively
- helps clients to have insight, consider alternatives, & make choices
- promotes dialogue
- accesses client's resources
- supports self-efficacy
- this style takes time & skill
- some people want info or direction best facilitated by other counselling styles
78
Which counselling approach(es) is most useful
- combined approach
- use diff styles in diff situations, depending for example on particular setting, client, stage of change & goals for that counselling session
79
Why is "measurement" better than "test"
test implies a judgement
80
When reading results of a test, what should u start off with first
start w/items scored well on and conclude w/weakest area
81
Traditional health education is strong on what "three M's"
1. Market ; identifying a target market or audience
2. Message ; tailoring messages to suit the values, attitudes, & language of that market
3. Media ; using media (t.v., radio etc.) to deliver msg to target market
82
Lawrence W. Green asserts the traditional approach to health education isn't wrong but ____ and ___
- too narrow and limited
83
Lawrence Green's health education definition
- health education is a process which bridges the gap btwn health info and health practices. health education motivates the person to take the info & do smtg w/it -- to keep himself healthier by avoiding actions that are harmful & forming habits that are beneficial
84
What is Green's health education definition similar to
health motivation
85
Green's health educational planning process called?
PRECEDE-PROCEED
86
What are Green's 5 fallacies
1. Empty vessel (container)
2. Some methods inherently better
3. More is better
4. Technology is the solution
5. Teacher motivates the student
87
What is and why is the empty vessel false
- this fallacy states that students know nothing, they wait eagerly to have their minds filled w/knowledge. 'expert' casts 'his pearls of wisdom' for students to gobble up
- by young adulthood, students know a lot and start semester w/lots of related knowledge and lifetime experience, attitudes, beliefs, & values. not starting from "ground zero"
88
Why are 'some methods are inherently better' false
- nothing inherently superior about any one method
- method should be viewed as a tool, and should be appropriately applied. most effective teacher will be those w/biggest tool kit, the sensitivity to understand their audience, & the wisdom to use the best tool for the job at hand
89
Why is more is better false
- the amt of learning not related to amt of material presented, but to the degree of active involvement of the listener. passive participation is less effective
90
Why is technology is the sln false
- new things tend to arouse curiosity and interest, but high-tech can be useless too e.g. clickers if q's posed too hard for group. low-tech like blackboards can also work very well
- use appropriate tech and a process that engages the learner
91
Why is the teacher motivates the student false
- u cannot motivate someone, motivation isn't smtg u can give to someone
- u can only help his or her own motivational processes to influence behaviour
92
Lebanese poet Kahil Gibran views the teacher is a ___ rather than as expert
guide
93
Markets can be populations of what three things

3. Organizations
94
What is market segmentation
The division of the total market into relatively homogeneous but distinct segments
95
Purpose of market segmentation
used to identify target audiences & strengthen a campaign's effectiveness in reaching selected segments. segments usually respond to campaigns elements differently & diff techniques required to reach & motivate various segments
96
3 ways to segment a population are
1. Geographically: by location
2. Demographically: by socio-economic group, characterized by age, income, sex etc.
3. Psychographically: by such things such as attitudes, values, lifestyles, & opinions
97

99
Commonly used tool in segmenting a market for social marketing is what model
Stages of Change Model
100
Stages of Change Model explains what
- explains the psychological process individuals experience as their behaviour changes
- this model tends to divide population into segments w/common knowledge, attitudes, beliefs, & behaviours relative to issue at hand
101
What are the 6 stages in Stages of Change Model and a bit of each
1. Pre-contemplation; no intention to change behaviour. in denial or uninformed of the need to change
2. Contemplation; acknowledge problem & beginning to think about changes
3. Preparation; plan to take action w/in next month & make adjustments b4 behaviour change
4. Action; modify behaviour & surrondings to facilitate change
5. Maintenance; work to consolidate the gains attained during action phase, struggle to prevent lapses and relapse
6. Termination; new behaviour is fully adopted
102
In 2005 health canada conducted survey on ___ and ___ related to healthy eating, physical activity, and sport participation in preparation for a campaign on Healthy Living

1. Current behaviour
2. Perceptions of the benefits of healthy eating & PA
3. Need for info on healthy living subjects
4. Current actions/intentions to improve their families health
104
Health canada's research study gave four diff segments, w/diff lvls of commitment to healthy living & w/diff info needs

3. Quiet conformers. strong work ethic and social conscious. follow rather than lead. against smoking and other substance abuse
4. Concerned Moralists; very traditional attitudes towards family, sexuality etc. follow rather than lead. need the support and approval of others
5. Passive Luddites; more tolerant of, if not involved in, substance use/abuse. some degree of independence, but concerned about how one seen by others
6. Small Town; traditionalists. traditional attitudes and beliefs. ambitious, self-confident, anti-substance use/abuse
7. Big City Independents; independent. not easily influenced. "loners" more than team player. Wide range of substance-use behaviours
108
Analysis of youth identified what 3 psychographic groups based on drug use attitudes n behaviour, particularly use of marijuana
1. Active - larger percentage of older youth. willing to experiment w/drugs. highest proportion of friends that use drugs
2. Contemplators - equally split btwn younger n older teens. some use marijuana, but infrequently. least likely to be leaders
3. Inactive - least likely to have tried marijuana. believe drug use is dangerous. majority prefer not to be w/those that use drugs.
109
What is target marketing
the selection n concentration of marketing resources on one or more market segments (often more than 1 target audiences selected, audiences then divided into primary n secondary target audiences)
110
what is TARPARE
A model that can help to analyze market segments w/a view to choosing target audiences where the greatest impact is likely to occur
111
Define all letters of TARPARE
T (total # of people in segment) - segments encompassing larger groups of individuals more attractive
AR (At Risk) - segments at higher lvls of risk should be given priority
P (Persuadability) - a segment that is easily persuaded to change should be given a higher priority, as it will take fewer resources to establish a behaviour change
A (Accessibility) target audiences that are easier to reach w/messages are more attractive as less work n fewer resources needed to make an impact
R (Resources required) - the fewer the resources required, to meet the needs of the target market, teh greater expected return on investment
E (Equity) - the need to target specific disadvantaged segments
112
Why were women aged 25-39 chosen as primary target audience for Eat Well. Have Fun. You can prevent type 2 diabetes campaign
- they were accessible n often made decisions that contributed to the health of their children, spouses (men, at higher risk) n parents (elderly, at higher risk) thus disseminating msgs to all intended targets
113

119
Health Canada Vitality campaign chose their target audience adults aged 25-44. What was their major obstacle to eating nutritiously n engaging in regular physical activity
lack of time
120
Health Canada Vitality campaign chose their target audience adults aged 25-44. Based on research, the program integrated what aspects

121
What is social marketing
adaption of commercial marketing techniques to achieve social goals
122
5 common social marketing techinqiues
1. Market segmentation
2. Target marketing
3. Consumer research
4. Mass media
5. Tracking of results, i.e. 'outcome measures'
123
rather than trying to sell product or service, social marketing tries to ____
achieve certain social goals
124
Health canada's view of social marketing
"social marketing combines the best elements of the traditional approaches to social change in an integrated planning n action framework, n utilizes advances in communication tech n marketing skills. it uses marketing techniques to generate discussion n promote info, attitudes, values, n behaviours. by doing so, it helps to create a climate conducive to social n behavioural change"
125
Wagnam stated social marketing can only be used effectively when (4)...
1. We r aware of beliefs n values of target audience
2. new behaviour is accessible to target audience
3. msg promoted repeated using variety of formats
4. appropriate method of evaluation used to measure behavioural change
126
Boslaugh said goal of audienc segmentation is...
to identify population subgroups that are homogeneous w/respect to certain variables associated w/a given outcome or behaviour. when such groups identified and understood TARGETED INTERVENTION STRATEGIES can be developed to address their unique characteristics n needs
127
When Boslaugh applied diff segmentation approaches he conlcuded that
simple segmentation strategies such as those replying on demographic variables alone provide little improvement over no segmentation at all. audience segmentation appears to yield more homogeneous subgroups when psychosocial n health status factors r combined w/demographic variables
128

Main msg in Activity Monitor Chapter
In a lot of these interventions, behaviour relapses after the fact
153
Strategies to estimate child activity levels
1. Reports by ‘key informants’, e.g. parents, teachers (self-reports in children less accurate than in adults)
