- Successful for a range of health behaviours eg. breast self-examination, vaccinations, diabetes Mx etc.
> perceived barriers have been demonstrated to be the most important factor for addressing behaviour change in patients.
135
Explain the 'Theory of Planned Behaviour'.
- Proposes the best predictor of behaviour is 'intention'
- Intention is determined by:
> a person's attitude to the behaviour
> the perceived social pressure to undertake the behaviour, or "subjective norm"
> a person's appraisal of their ability to perform the behaviour, or their perceived behavioural control.
136
Critique the Theory of Planned Behaviour.
- Lacks direction or causality
- Doesn't account for emotions eg. fear, threat, positive affect etc. which might disrupt 'rational' decision making.
- Habits + routines bypass cognitive deliberation + undermine a key assumption of the model.
- Relies on self-reported behaviour.
137
Give a summary of the Theory of Planned Behaviour
- Rational choice model
- Attitudes, subjective norms, perceived behavioural control are the major determinants of intentions.
- Takes into account the importance of social pressures + norms, as well as perceived control.
- Useful for predicting people's intentions; not as successful for predicting actual behaviours.
138
Give a summary of the Theory of Planned Behaviour
- Rational choice model
- Attitudes, subjective norms, perceived behavioural control are the major determinants of intentions.
- Takes into account the importance of social pressures + norms, as well as perceived control.

141
Give 3 disadvantages of the transtheoretical model / stages of change model.
- Not all people move through every stage. Some relapse. Some miss out stages completely.

- Doesn't take into account values, habits, culture, social + economic factors
142
Summarise the transtheoretical model / stages of change model.
- Examines the process of change, rather than factors that determine behaviour.
- Allows for interventions to be tailored to the individual according to what stage they are at.
143
Summarise 'Motivational Interviewing' as a theory of behaviour change.
- A counselling approach -> initiates behaviour change by resolving ambivalence.
- Clinical impact has been shown in problem drinkers.

- Assessment of risk perception
- Impact of past behaviour / habit
- Automatic influences on health behaviour
- Predictors of maintenance of health behaviours
- Social environments
145
What does the NICE guidance say about behaviour change?
- Interventions to change health related behaviour should work in partnership with individuals, communities, organisations + populations.
- Typical transition points include:
> leaving school
> entering the workforce
> becoming a parent
> becoming unemployed
> retirement + bereavement

147
Define 'evaluation' of health services.
The assessment of whether a service achieves its objectives; assessment of a wide range of health-related activities.
148
What 3 components make up the 'Framework for Health Service Evaluation'?
- Structure
- Process (+ output)
- Outcome
149
What is 'Process' - part of the Framework for Health Service Evaluation - concerned with?
- What is done?
eg.
- Number of patients seen in A+E
- The process through which patients go in A+E.
150
What is 'Outcome' - part of the Framework for Health Service Evaluation - concerned with?
Classification of health outcomes:
- Mortality eg. 30 day mortality rate
- Morbidity eg. Complication rates
- Quality of life / PROMs (Patient Reported Outcome Measures)
- Patient satisfaction
151
List Maxwell's Dimensions of Quality (as applied to Quality of Healthcare).
- Effectiveness: does the intervention produce the desired effect?
- Efficiency: is the output maximised for a given input?
- Equity: are patients being treated fairly
- Acceptability: how acceptable is the service offered to the people needing it?
- Accessibility: is the service provided? Geographical access; costs for patients, information available, waiting times.
- Appropriateness: is the right treatment being given to the right people at the right time? Overuse / Underuse / Misuse?
152
Give examples of qualitative methods of evaluating healthcare services.
- Consult relevant stakeholders eg. patients, staff, relatives
- Qualitative methodology:
> Observation
> Interviews
> Focus groups
> Review of documents
153
Give examples of quantitative methods of evaluating healthcare services.
- Routinely collected data -> hospital admissions, mortality
- Review of records -> e.g. medical, administrative
- Surveys
- Special studies eg. using epidemiological methods.

- Review of records -> e.g. medical, administrative
- Surveys
- Special studies eg. using epidemiological methods.
155
Give some general principles to consider when evaluating Health Services.
- May be prospective OR retrospective
- Define what the service is / what it includes
- What are the aims / objectives of the service?
- Framework, Structure, Process, Outcome
- Methodology used -> qualitative / quantitative / mixed methods
- Results, conclusions + recommendations
156
List some factors which contribute to the promotion of excessive calorie intake.
- Genetics
- Employment (shift work)
- Environmental cues
- Decreased physical activity
- Sleep
- Psychological factors
157
Define 'malnutrition'.
Deficiencies, excesses, or imbalances in a person's energy &/or nutrient intake.
158
What are some of the consequences of undernutrition?
- Stunting: low height for age
- Wasting: low weight for height
- Underweight: low weight for age
- Micronutrient deficiencies / insufficiencies -> a lack of important vitamins + minerals.
159
What are some of the consequences of being overweight?
- Obesity
| - Diet-related non-communicable diseases eg. Heart disease, stroke, diabetes, cancer
160
Give examples of early influences on feeding behaviour.
- Maternal diet + taste preference development
- Breast feeding -> for taste preference + body weight regulation
- Parenting practices
- Age at introduction of solid food
161
How does the maternal diet lead to early flavour exposure for the baby in utero?
- Baby's taste + olfactory systems can detect flavour information prior to birth
- Amniotic fluid + human milk transmit volatiles from the maternal diet, providing early chemosensory experience.
162
How might breast feeding be considered to be a public health issue?
- Prevalence of breastfeeding is particularly low among very young mothers + disadvantages socio-economic groups, potentially widening existing health inequalities.
163
What are the 3 components of breast milk?
- Colostrum
- Foremilk
- Hindmilk
164
Describe the composition of colostrum.
- High protein
- Low fat
- Contains lots of antibodies
- Delivers nutrients in a very concentrated, low volume form
- Mild laxative effect -> encourages bowel movements.
165
Give 4 properties of breast milk which are beneficial for the baby.
1. Anti-infective: bifidus factor, white cells, oligosaccharides
2. Efficient digestion: contains enzymes eg. lipase, lysozyme
3. Gut protection:
- epidermal growth factor
- secretory IgA
- anti-inflammatories
4. Everyday health: Antibodies, viral fragment,s, lactoferrin (aids dental hygiene.
166
How might parents influence positive feeding behaviours?
- Modelling 'healthful' eating behaviours
- Responsive feeding: recognizing hunger + fullness cues
- Providing a variety of foods
- Avoid pressure to eat
- Not using food as a reward
- Indulgent / neglectful feeding practices.
167
What is 'chemical continuity' with regards to feeding behaviours?
Transmission of certain flavours from the maternal diet via amniotic fluid + then breast milk.
168
What are the 3 distinct illnesses encompassed by 'eating disorders'?
- Anorexia nervosa
- Bulimia nervosa
- Binge eating disorder
169
Define 'eating disorder'.
Clinically meaningful behavioural or psychological pattern having to do with eating or weight that is associated with distress, disability, or with substantially increased risk of morbidity or mortality.
170
Define 'disordered eating'.
Restraint, strict dieting, disinhibition, emotional eating, binge eating, night eating, weigh + shape concerns, inappropriate compensatory behaviours that do not warrant a clinical diagnosis.
171
What are the 3 basic forms of dieting?
1. Restrict the total amount of food eaten
2. Do not eat certain types of food
3. Avoid eating for long periods of time
172
What are the problems with dieting?
1. Dieting is a risk factor for developing eating disorders
2. Dieting results in a loss of lean body mass, not just fat mass.
3. Dieting slows metabolic rate + energy expenditure
4. Chronic dieting may disrupt 'normal' appetite responses + increase subjective sensations of hunger.
173
Why is dieting so difficult for some patients?
Those susceptible to obesity (and who try to diet) appear particularly:
I) unresponsive to internal cue that signal satiety (when overconsuming) + hunger (when dieting)
ii) vulnerable to external cues that signal availability of palatable food.
174
What is the 'Externality Theory of Obesity'?
- Normal weight individuals responsive to internal homeostatic cues.
- Overweight individuals eat according to:
> external cues
> no compensation after preload
> time of day
> often lurid descriptions of desserts
> sensory food cues.
BUT the theory is too general
175
What is 'restrained eating'?
The deliberate attempt to inhibit food intake in order to maintain or to lose weight.
- effortful, cognitively demanding process: ignore feelings of hunger in order to adhere to self-imposed dietary rules.
Under certain circumstances, restrained eaters can be induced to overeat -> 'disinhibition'
-> "what the hell" effect: inability to maintain cognitive control of food intake.
176
Give a summary of the Restraint Theory (Boundary Model).
- Unrestrained eaters are intuitive + regulate food intake without conscious effort.
- Restrained eaters rely on consciously controlled processes to regulate food intake.
- Break down of dietary restraint leads to 'what the hell' cognitions
177
Give some examples of disinhibits which might lead someone to over eat (according to the Restraint theory / boundary model).
- High energy preloads / merely the belief of high energy preloads
- Large portion size, alcohol
- Cognitive load -> stress
- Strong emotion
178
Give a critique of the Restraint Theory / Boundary Model.
- Suggests a link between food restriction + over-eating
- Dieters, bulimics, anorexics report episodes of over-eating.
- Theory cannot explain restricting behaviour in anorexics
179
Why are some dieters more successful?
- Some people are more 'flexible' than 'rigid' in their dietary restraint -> results in decreased pre-occupation with food, decreased attentional bias to food cues -> longer term weight loss.
180
What is the 'Goal Conflict Theory' as applied to dietary restraint?
- Chronic dieters experience conflict between 2 incompatible goals: eating enjoyment vs weight control
- Individuals are motivated to pursue a weight loss goal.
HOWEVER, pervasive food cues in the environment prime the goal of food enjoyment ("external eating").
181
What is the 'Portion Size Effect'?
Consumption of large portion sizes of energy dense (ED) food facilitates over consumption.
In the absence of compensatory effects, large portions of energy dense food may be contributing to the increased prevalence of overweight + obesity.
182
What is the evidence behind the 'Portion Size Effect'?
- Associated with sustained increase in energy intake over several days without energy compensation.
- Evidence for individual + socioeconomic influences
- Most people don't know what constitutes an appropriate portion size for many foods + beverages.
