DPS Flashcards
Case-control study
Causes or risk factors
Looks back over time to check for common activities/exposures
Compares those with condition to control group and increase in exposure in condition group suggests risk factor
Cohort study
Harm or causes
Forward in time. Take group that got exposed to e.g. radiation and get very similar but unexposed group as control. Watch and see what happens (e.g. increased incidence of specific disease)
Qualitative study
Experience of the illness
RCT
Effectiveness of treatment
Cohort study with randomly allocated groups between control and interventional
Cross-sectional study
Looks at prevalance
The 4 A’s of studys
Assess (define question)
Access (search using medline etc)
Appraiase (how good study is)
Act (use info, taking into account limitations)
ODDS RATIO (OR)
odds of outcome in treatment group/ odds of outcome in placebo
RELATIVE RISK (RR)
risk of outcome in treatment group/risk of outcome in placebo group
What is Attachment?
emotional relationship that is specific to 2 people, endures over time and in which prolonged separation causes stress and sorrow
What are the phases of attachment?
Pre attachment phase (up to 3 months)
• Preference for contact with humans shown by smiling, nestling and gurgling
Indiscriminate attachment (up to 7 months) • Strangers can look after them without distress if they’re caring • Discriminate between familiar and unfamiliar people
Discriminate attachment (from 7-8 months)
• Requires infant to be able to discriminate between mother and others
• Actively tries to stay close to familiar people and has separation anxiety on separation
Multiple attachment phase (from 9 months)
• Strong additional ties and starts relationships with others
• Fear of stranger weakens but strongest attachment (mother) remains
What is the Psychoanalytic theory of attachment?
Babies become attached to their carer as they satisfy the baby’s instincitive needs
What is the behavioural theory of attachment?
Babies become attached to carer due to associating them with gratification and physiological needs
What is Bowlby’s theory of attachment?
It is the synchrony of action (baby faces) between the mother and the child in the first 36 months that provides attachment.
What are Mirror Neurones?
They fire when an action is watched and same neurones fired when the action is performed.
What is Ainsworth’s theory of Individual Variation?
An Attachemnt theory that there are 3 forms of attached children:
Anxious-avoidant type
• Distress caused by being alone but no difference if this is mother or other person.
• Play little affected by whether mother is present or absent
• Indifferent and actively ignores or avoids mother on return.
Secure attachment type
• Ignores mother (can be trusted)
• Plays happily regardless of whether mother is there, stranger is there or not.
• Distressed and play reduced if mother leaves
• Actively seeks mother on return and calms and continues play
• Mother and stranger treated differently but stranger can provide some comfort.
Anxious-resistant type
• Cries more than other types
• Difficulty using mother as secure base
• Very distressed when mother leaves. Seeks contact on return but simultaneously resists and shows anger.
• Actively resists strangers attempts to make contact
• Fussy and wary when mother present
What is Piaget’s Theory of child development?
Cognitive Development:
Series of fixed stages
Brain not finished developing til late adolescence
Continuous process of assimilation and accommodation
Birth- 2 yrs Sensoriomotor
Turn from reflex driven to goal driven
2- 7 years Preoperational
Develop language
Only aware of immediate environment
7-12 years Concrete operations
Start to differentiate between self and others
Understand more than one dimension of situation
Can only understand problems in the real world
12+ Formal operations
Hypothetical thinking starts
What is Erikson’s theory of Child Development?
Social development:
Each stage linked to psychosocial areas
Each stage struggle between 2 conflicting personalities
0-1 yrs Trust v Mistrus
1-2 yrs Autonomy v Shame and Doubt
• Primary social interaction with parents- feeding, holding on, letting go, toilet training. Start of autonomous will
3-5 yrs Initiative v guilt
• Development of conscience
• Enjoys group play
• Identifies with gender
6- puberty Industry v inferiority
• Primary social interaction outside home
• Role models
• Enjoys peer groups of same gender
• Learns from parents, peers + role models
Adolescence Identity v Role Confusion
• Primary relationships with peers/heterosexual relationships
• Identity crisis
• Coherent sense of self develops
• Distancing from family
• Orientated towards present rather than future
Children in hospital: Immanent justice (1-7yrs)
illness caused by bad behaviour or punishment. Child normally has limited experience of illness and no other obvious explanation. Preschoolers will abandon this with personal experience of the illness
Children in hospital:
Phenomenonism (3-7yrs)
cause of illness is spatially and temporally remote phenomenon.
Children in hospital:
Contagion (6-7 yrs)
Cause of illness located in people and linked by magic
Children in hospital:
Contamination (Concrete operations 7-12 yrs)
cause is external to child and is passed by touching (you’ve got germs)
Children in hospital:
Physiological (Formal operations 12+)
illness is malfunction of internal organs. Realise death is permanent.
Why do we age?
- Wear and tear- body is mechanical robot
- Cellular
- a. Hayflick limit- max no. of cell divisions
- b. Cross linking- proteins in cells make body stiffer.
- c. Free radicals- interact and cause damage
- d. DNA replication/repair malfunction - Rate of living- born with max physiological capacity
- Programmed cell death- genetically programmed to die
How do you perpare children for hospitals?
Preparing for hospitals- Encourage parents to stay.
Before admission- visits, videos, books.
On admission- show instruments, distraction strategies, short waits before operations.
What is Attribution theory?
There is a causal explanation for events/behaviours e.g. Kelley’s covariation theory
What is Kelley’s covariation theory?
That there are 3 factors that influence behaviour:
Consensus- do other people do the same in that situation?
Consistency- does behaviour reliably occur in this situation?
Distinctiveness- does it only occur in this situation?
What is an internal locus of control
relating to Kelley’s covariation theory of attribution, event/behaviour are attributed to individual e.g. individual is prime determinant of health state.
What is an external locus of control
Relation to Kelley’s covariation theory of attribution, event/behaviour are attributed to uncontrollable factors e.g. Luck and chance.
What is Fundamental attributional error
overemphasis of personality compared to environmental influences
What is Actor-observer attributional bias?
tendency to overestimate importance of environmental influences in explaining own behaviour
What is False Consensus?
Tendency to believe own views widely shared
What is a self-serving attributional bias?
Tendency for individuals to attribute more .responsibility to themselves for successes rather than failures
What is somatisation in terms of attribution theory?
Patients with the wrong attribution of the cause
What is an Attitude?
learned response, relatively enduring that influences and modifies our response towards that person or object
What are the three aspects of Attitude?
Cognitive- beliefs and preconceived expectations
Affective- feelings or emotions aroused by object
Behavioural- action towards object
What is stigma?
hostile or negative attitude towards distinguishable group with no reinforcing evidence, normally as result of a generalisation
