Q

What were the findings of the UK population study?(ref?)

A

After 11years 200,000 people were followed up and those who had performed all 4 behaviours studied were 4x more likely to be alive than those doing none of them. (Khaw et al., 2008). This was controlling for age, gender, BMI and SES.

Q

Describe Yates et al’s (2008) study and their findings.

A

They studied more than 2000 70yo men over 20 years and found that:

  • The average healthy 70 year old had a 54% change of living to 90
  • This was reduced to 44% for those with sedentary lifestyle
  • 26% if obese
  • 22% if a smoker

Q

HBM as a predictive model: Outline the findings of Janz and Becker (1984)

A

Review of 18 prospective studies looking at the significance ratios for each of the HBM predictors and behaviour.
Severity = 65% (11/17)
Susceptibility = 82% (14/17)
Benefits = 81% (13/16)
Barriers = 100% (11/11)
- There were very few studies of cues to action and health motivation and therefore no support.

Q

HBM as a predictive model: Outline the findings of Harrison et al (1992)

A

Meta-analytic review of 234 studies, only 16 met criteria for including the four major constructs and reliability checks revealed weak operationalisations.
Sample weighted average correlations:
Severity = 0.08
Susceptibility = 0.05
Benefits = 0.13
Barriers = -0.21
- Only 0.25-4.4% of behaviour variance explained by the HBM. However this study used extremely harsh inclusion criteria and potentially undermined combined effects.

A

P = 74 patients presenting with asthma at A&E
I = 1. Health beliefs assessed 2. HBM advice given (susceptibility to asthma, seriousness of asthma and benefits of visiting the GP to obtain treatment and avoid complications)
C = group just advised to go to GP with no supporting information
O = % who made and who kept GP appointment
- Active group were both significantly more likely to make and keep GP appointment.

39
Q

Outline Madden’s (1992) findings

What do Madden’s (1992) findings suggest?

A

That the addition of PBC to the model adds most to the prediction of behaviours which are considered as generally less controllable.

41
Q

A

Hill, Abraham and Wright (2007)

42
Q

PICO Hill, Abraham and Wright’s (2007) TPB intervention study

A

P - 503 6th form students with low exercise rates
I - 20 minute school session to read leaflet and answer questions on it included in a quiz
C - Control group with no intervention
O - Exercise change at three week follow up

43
Q

Describe the leaflet used in Hill et al’s (2007) TPB intervention.

A

2 pages of persuasive arguments which:

  • Raised awareness of types of exercise
  • Emphasised their advantages
  • Hilighted others exercising and approval of exercise by profiling admired sports personalities
  • Bolstered SE ad control
  • Set a goal (one more 30 min session per week)
  • Quiz to help memory
44
Q

Describe the outcome of Hill et al’s (2007) TPB intervention study.

A

Change in number of 30 min sessions over 3 weeks before and after the intervention:

  • Intervention = +0.69 sessions
  • Control = -0.14
45
Q

Who conducted a Meta-Analysis on the efficacy of the TPB in prospective predictions of health behaviours?

A

(McEachan et al., 2011)

46
Q

What analysis was used by McEachan et al (2011) in their Meta-Analysis on the efficacy of the TPB in prospective predictions of health behaviours?

A

Hierarchical exploration of moderators to avoid confounding.

47
Q

How many studies were identified in McEachan et al’s (2011) Meta-Analysis on the efficacy of the TPB in prospective predictions of health behaviours?

A

237

48
Q

In McEachan’s (2007) Meta-Analysis on the efficacy of the TPB in prospective predictions of health behaviours, __________ and _________ moderated the model’s predictive validity.

A

Behaviour of focus

Methodological moderators

49
Q

In McEachan’s (2007) Meta-Analysis on the efficacy of the TPB in prospective predictions of health behaviours, how did behaviour moderate the models predictive validity?

A

Exercise and diet were the best predicted behaviours (23.9 and 21.2% of the variance explained respectively)
Safer sex and drug abstinence were the worst explained (13.8 and 15.3%)

50
Q

In McEachan’s (2007) Meta-Analysis on the efficacy of the TPB in prospective predictions of health behaviours, how did methodological moderators moderate the models predictive validity?

A

Age of the sample - Students were better predicted for exercise, adolescents were better predicted for abstinence
Behaviours assessed in the shorter term and using self report rather than objective measures were better predicted (Power, demand char?)

51
Q

Could the TPB be improved?

A

Many additions have been suggested including descriptive norms, moral norms, anticipated regret and other affective expectations - all of which go some way to improving the TPB (See conner & Abraham, 2001) (LOOK UP RAA)

52
Q

Model 3: Social Cognitive Theory (SCT; ref?)

A

Bandura (1982, 1997)

53
Q

Describe model on card 8.

A

See card 8.

54
Q

The SCT has good __________.

A

Predictive validity

55
Q

Though the SCT is theoretically distinct from the TPB, it has similar practical implications for HP if we presume that:

A

Goals = intentions
SE = PBC
Outcome expectations = Attitudes and SNs

56
Q

_____________ may be important to behaviour change and the SCT may be more practical in presuming these have direct effects on ________ and _____ rather than being mediated by other cognitions, as assumed by the ____.

A

Sociocultural influences/ goals/priority/TPB

57
Q

According to a summary SCM model, there are three factors which are necessary and sufficient antecedents to behaviour, what are they and who developed this model?

A
  1. Strong intention
  2. Skills necessary
  3. No environmental barriers
    (Fishbein et al., 2001)
58
Q

According to the summary model, what are the cognitive antecedents of strong intention?

A
  1. Belief that benefits outweigh costs (attitude)
  2. Perception of more social normative pressure to perform the behaviour than not to
  3. Perception that performance is consistent with self image
  4. Emotional reaction to performance is more positive than negative
  5. Believes self capable across a range of circumstances (PBC)
    - Basically everything in the TPB
59
Q

What are the advantages of using SCMs?

A
  • Clear theoretical background for research
  • Reliable and valid measures are available
  • Can include in moderation/mediation analysis to clarify why intentions do/dont work
60
Q

Do messages in leaflets promoting condom use target modifiable determinants of condom use? A content analysis of 36 UK and 35 german leaflets: Describe

A
  • Coding manual used to analyse leaflets included 20 correlate representative categories which correspond to cognitive and behavioural correlates of condom use, identified by theory based research e.g. severity of disease, attitude to behaviour, self efficacy.
61
Q

Do messages in leaflets promoting condom use target modifiable determinants of condom use? A content analysis of 36 UK and 35 german leaflets: Results

A
  • Few content differences between english and german leaflets
  • Both hi lighted intro on how people become infected with HIV and advice on contacting HCPs
  • Few mentioned delaying or abstaining
  • 25% included text of more than 10 correlate, this rose to 2/3 with 1SD above mean applied as a measure of ‘frequent’ inclusion.
    = Not EBHP
