Q

Genetic Explanation - OCD

A

Idea = genetically passed in DNA & inherit vuln if mems of bio fam have
37% have parents w/ OCD & 21% have siblings w/ OCD
Candidate genes create vuln = polygenic over 230 pos
SERT gene = serotonin - low levels of serotonin
COMT gene = dopamine = high levels bc of low activity of enzyme that breaks down DA
Certain genes can cause in some but not others must = m factors

Q

Neural Explanation - OCD

A

Linked to breakdown in immune system func - lymes disease & flu
Neuro chems - DA & S - PET scans show low levels of S & drugs that inc S dec symptoms
Basal ganglia - responsible for innate psycho motor func Rapport & Wise suggested that hyper sen = rep beh
Orbitalfrontal cortex = worry circuit inability to filter small worries PET scans show high levels of anxiety
Thalamus inc motivation to clean & check safety OFC inc anxiety & planning to avoid

Q

Genetic Explanation Evaluation

A

Most evidence = twin studies - Nestadt reviewed cases & found 68% MZ & 31% DZ concor - not all genes
Stewart et al (2007) performed gene mapping on OCD patients & found variant of OLIG-2 gene - little practical app too many genes involved
Fam Studies - but could also support environ
May have genetic vul but then = triggered by stressor - Cromer (2007) over 1/2 of OCD patients in sample had traumatic event & inc OCD after may = m prod to focus on environ causes not all OCD = completely gen

Q

Neural Explanation Evaluation

A

Hu (2006) comp s activity in 169 OCD p’s & 235 non OCDs found lower S in OCD
Zohar et al (1987) gave MCCP dec S levels to 12 non OCD & 12 OCD symptoms inc
Allows med to = developed & advances in tech to investigate brain areas& advances in tech to investigate brain inc accuracy
Drugs not completely effective but = cheaper than CBT - just bc SSRIs dec doesn’t mean causes
Compulsions explained by abnor in BG not thoughts

Q

OCD treatment

A

Drug therapy SSRIs selective serotonin reuptake inhibitors = anti deps inc S levels usually 12-16 weeks works on inc certain neurotrans prevent S reabsorp cause OFC to function at normal levels e.g., flurotine
Anticyclic & anti-psychs dec DA if SSRIs don’t work
Therapy assumes = chemical imbalance often w/ CBT if reduce emo symps patient can engage m some work w/o drugs

Q

OCD Treatment Evaluation

A

Julian (2007) reported on studies of SSRIs show although symps don’t fully disappear 50-80% of p’s improve
Not a cure dec symps - side effects e.g., sleep disruption, headaches & appetite loss
Only for adults not young ppl
Don’t necessarily dec OCD directly but = cheap but need therapy for LT reduction
Some OCD after trauma - drugs not effective?
Soomro (2009) research shows SSRIs dec OCD severity & aren’t disruptive
Unreliable evidence may = skewed by drug companies

Q

Becks Negative Triad

A

Negative views about the world, the future and the self - some = m vul to depression = 3 parts
Faulty information processing - when attend to the negative aspects of a situation & ignore positives, blow small problems out of proportion & think in ‘ black and white’ terms.
Negative self schema - Interpret all info about themselves in a negative way
Negative triad - person has a negative view of themselves (thinking I’m a failure and it’s negative impact upon self esteem), negative view of the world (e.g. the world is a cold hard place) and negative view of the future (e.g. there isn’t much chance that the economy will get any better)

Q

Ellis’ ABC Model

A

Depressives mistakenly blame external events for unhappiness
= their interp of events to blame for distress
A = activating event (lose job) B = belief (can’t do job) C = consequence (cog bias)

20
Q

Depression Evaluation

A

Saisto et al (2001) studied expectant mothers - those who didn’t change personal goals to match motherhood & indulged in negative thinking had inc dep - sups neg thoughts = cause
Tony & Glazioli - assessed 65 pregs for vul b4 & after - women w/ high vul had post natal dep - cogs developed b4 preg - shows triad inc likelihood
Not all depressives have distorted view
Loses of sup research based on scientific prins allowing subj testing high degree of success shown in development of treatments acknowledging other aspects including genetics lower success w/ bipolar

21
Q

Treatment of Depression

A

CBT - REBT - work out activating event, challenge irrational thoughts, & change consequences
Client & therapist decide how belief can be challenged - role play / homework
Way you think about the problem not the problem- can overcome w/ pos cogs
Aim = positive & rational

22
Q

Evaluation of Treatments of Depression

A

Lincoln et al (1977) used questionnaire on stroke victims with clinical depression found reported dec in symps - used self report could = affected by SD
Embling (2002) gave one group antidepressants & other drugs & 12 CBT sessions had to record dysfunctional thoughts - CBT expressed improv emos dep = less likely to express emos CBT & drug = m effective lack of dep emos may = causal not effect could improve bc saw someone
Cog approach puts responsibility on person some irrational thoughts = true
Don’t know what comes 1st emo / cog

23
Q

Phobias

A

Anxiety disorders characterised by extreme irrational fears

24
Q

Behavioural Characteristics of Phobias

A

Avoidant/ anxiety response, disruption of func, interfere bc avoidance = so strong

25
Q

Emotional Characteristics of Phobias

A

Persistent excessive fear, fear of exposure to phobias stimulus

26
Q

Cognitive Characteristics of Phobias

A

Recog of exag anxiety

27
Q

Behavioural Explanation

A

2 process model = acquisition & maintenance
CC when 2 stim paired together to cause phobia UCS + UCR of fear - NS = NR NR + UCS = UCR fear = CS + CR
OC dog phobia maintained consequences & reinforced by avoiding stimulus feel better dec anxiety avoidance response likely again

28
Q

Phobia Evaluation

A

Watson & Rayner (1920) little Albert CC fear of white rat no unusual beh b4 tried to play w/ - presented w/ steel bar hit = loud bang showed fear = gen to sim objects e.g., rabbit & fir coat
2 part model ignores evolutionary influence suggests humans have tendency to = phobic of harmful things - genetics & evolution add a preparedness to learn phobia - genetic vul
Behav treatments e.g., SD suggest = learnt require re learning to undo
Not everyone expers trauma b4 phobia not everyone develops after trauma

29
Q

Phobia Treatments

A

SD: based in CC taught relax - leads to reciprocal inhibition, fear hierarchy, covert desen
E.g., snake phobia put in mild anxiety situ - snake in tank relax - inc interaction phobia = removed
Flooding: (implosion) fear taken to extreme until can no longer feel fear due to exhaustion so re associate w/ calm - snake = direct contact no escape anxiety = not sustainable so removes phobia.

30
Q

Evaluation of Treatments of Phobias

A

Jones (1924) used SD to remove a fear of white fluffy animals in little Peter presented rabbit gave food = positive association
SD mainly used for those who can learn relax & have vivid enough imag invivo = better else no guarantee will work
Works best on simple phobias
Wolpe (1960) used flooding to remove phobia of cars girl in car for 4 hrs shows effectiveness
= ethical consids due to psych harm not suitable for those w/ poor health - can cause heart attacks

31
Q

Deviation from Social Norms

A

Society has unwritten social rules & when ppl deviate from social norm could indicate a mental illness - identifies what = normal / acceptable in a culture

32
Q

DSN examples

A

Anorexia breaks rules of normal, eating behaviour

33
Q

DSN Positive Evaluation

A

Takes into account situational norms e.g., ok to wear bikini at beach not in shopping centre
Takes into account developmental norms e.g., ok for child to scream:adult = weird
Both could indicate SZ

34
Q

DSN Negative Evaluation

A

Changes overtime e.g., homo used to = mental illness & unmarried preg women - institutions in early C20
Cultural relativism norms vary across cultures - not normal for men to wear skirts but in Scot is - diagnosis & mental illness = classified dif in dif countries - someone labelled as abnormal using personal standards - SZ
Social control - Szasz (1974) claimed mental illness = concept used for social control = non conformists

35
Q

Statistical Infrequency

A

Idea that behav that = SIF = abnor
Normal distribution curve for all behav & those on extremes = sif = indication of mental illness
Normally about 5% of pop outside curve
E.g., low IQ = below 70

36
Q

SIF Evaluation

A

If = genius deviate doesn’t mean mentally ill deviation can = positive doesn’t need treatment IQ over 130
Where do you draw the line many disorders e.g., depression = variable
Not everyone benefits from label may feel m upset and weaken quality of life if labelled as abnormal

37
Q

Failure to Function Adequately

A

When individual can’t cope w/ everyday life - suffering abnor

38
Q

Maladaptive

A

Addictions can = maladaptive if stop going to work
But homelessness = maladaptive but not nec mentally ill

39
Q

Personal distress

A

Depression
Under some circumstances e.g., bereavement would = abnor not to feel grief

40
Q

Observer Discomfort

A

Families of alcoholics suffer

41
Q

Unpredictability

A

Sz
But someone’s behav may = unpred bc unaware of reasons not mental illness

42
Q

Unconventionality

A

Depression = quite common
Some = rare e.g., genius but not prob

43
Q

Irrationality

A

Bipolar can cause
But Darwin called irrational

44
Q

FFA Evaluation

A

Psychopaths e.g., Harold Shipman can func v well in Soc wouldn’t = diagnosed but = mentally ill
Culturally relative - func norm in 1 country = not in another can = dif diagnosis
Subjective judgement - person doing assessment would = subjective so dif opinions

45
Q

Deviation from ideal mental health

A

Looks for signs of wellbeing if have all 6 then fine missing 1 could = mental illness
1. Autonomy 2. Positive self view 3. Resisting stress 4. Self actualisation 5. Accurate perception of reality
6. Environmental mastery - coping w/ change

46
Q

DIMH Evaluation

A

Can we diagnose mental & physical the same
Some culs can’t make choices so never norm = cultural relativism - based on western ideals
Self actualisation only applies to individualistic culs not col would find inc abs in non w culs & non MC groups
