Q

how are diagnoses in psychopathology descriptive?

A

it identifies a particular problem is present based on a collection of features. the cause of explanation is not inherent in the diagnosis - associated features of possible explanations can be identified, but are not essential to the diagnosis

Q

validity of clinical diagnosis

A

the meaning or importance of the measurement

  • does the diagnosis tell us anything useful
  • can we make informed decisions from this information?
  • does it meaningfully differentiate amongst similar problems?

Q

purpose of assessment

A
  • To determine if psychopathology is present
  • To characterise (or formulate) the ‘problem’
  • To inform treatment planning/priorities
  • To predict likelihood of risk and guide decision making
  • To establish a baseline against which ‘change’ might be monitored
  • To establish a shared language from which to progress

58
Q

transcranial magnetic stimulation

A

A metal coil that contains an electric current is held to the side of the head and stimulates parts of the brain.
Given daily. Lower risks of seizures than ACT. Used in “treatment resistant depression”. Seemingly short term effects

80
Q

Blended tratment

A

an eclectic or integrative treatment approach: drawing from each of the mentioned approaches depending on the disorder being treated or stage of treatment

  • Perhaps consistent with a biopsychosocial aetiological model?
  • Difficult to evaluate/replicate? How to describe? “evidence-base”?
81
Q

Early views about treatment efficacy

A
  • Eysenck: psychotherapy does virtually nothing
  • Up to 2/3rds of people improve with no treatment (in fact, it is usually less than this); “spontaneous recovery”
  • What is “no treatment” and “treatment”
  • Role of extra-therapeutic factors/external factors
82
Q

General statistics of treatment efficacy

A
  • Works for many but not all people
  • Meta-analysis (Smith and Glass, 1977) suggests that those who receive psychotherapy generally do better than those who don’t
  • The average client is better off than 80% of individuals who remain untreated (fig 3-1 of your text book)
  • Two-thirds of clients who seek therapy improve, only one-third who do not seek therapy improve
  • Most improvement occurs in the first six months
83
Q

when do benefits of psychotherapy diminish

A

• Many benefits of psychotherapy diminish in the year or two after treatment ends (Westen &
Bradley, 205)

84
Q

YAVIS!

A

Clients improve more when they are “Young, attractive, verbal, intelligent and successful”

85
Q

how do we know what works?

A
  • Hard to know what the active ingredients are
  • Treatment fidelity, especially in eclectic therapy can complicate
  • The selection of “trial participants” and their representativeness (esp. comorbidities)
  • Nature of trial (Effectiveness and efficacy)
86
Q

efficacy studies

A

tightly controlled
– e.g. treatment versus no treatment
– High internal validity, lower external validity

87
Q

effectiveness studies

A

correlated
– Cannot identify cause and effect
– May yield useful descriptive information

88
Q

common factors of different treatments

A

While a lot of research has examined individual models of treatment, research has consistently found that the benefits arise from factors that are shared across treatment modalities

Much of the effectiveness of different psychotherapies can be explained by common factors rather than the specific content of the model

89
Q

how are positive outcomes of treatment predicted?

A

– Therapist warmth, empathy and genuineness

– The client’s rating of therapy relationship is the single most important aspect (Sloane, et, 1975)

90
Q

Common factors in brief psychotherapies

A
  • Assessment and treatment is offered soon after problem identification
  • Therapeutic alliance is established quickly & used effectively
  • Client encouraged to express strong emotions or troubling experiences
  • A flexible approach is used to choose therapeutic techniques
  • Goals of therapy are limited and specific (narrowly focused) & therapist is directive
91
Q

placebo effect

A

Beliefs/expectations about treatment efficacy play a role; some treatment gains may be attributable to a
placebo effec

92
Q

solutions to placebo effect

A
  • Placebo-control groups
  • Double-blind studies (difficult to conduct because the therapist knows which therapy they are using).
  • Meta analysis
93
Q

what should a therapist adopt in determining a treatment for a specific disorder?

A

different treatments are more effective for particular disorders. Clients should be informed about research evidence and treatment alternatives. Thus therapists should adopt a scientistpractitioner
model of service delivery; irrespective of treatment approach (single-case experimental design)

94
Q

Treatment decision making

A

Concept of evidence based practice – “the integration of best available research with clinical expertise in the context of patient characteristics, culture and preferences”

95
Q

treatment choices should be guided by…

A

– Evidence (in a broad sense)
– Client characteristics
– Client preferences
– Culture

96
Q

Holistic treatments

A

In addition to treating specific symptoms,
treatments may target broader factors that may
exacerbate, prolong or complicate mental illness
– Housing
– Employment
– Social engagement and social support
– Domestic and family violence

97
Q

what are the stats of treatment seeking?

A

ABS (2008) National Survey of Mental Health
and Wellbeing
– Only 35 per cent of Australians with anxiety and
depression access treatment.
– Men are less likely to seek help than women, with
only 1 in 4 men who experience anxiety or depression
accessing treatment.

98
Q

what are some potentailly harmful psycholitical therapies?

A
  • critical incident stress debriefing
  • scared straight
  • recovered memories
  • boot camp
99
Q

critical incident stress debriefing

A

involves process trauma too soon and may cause increased risk for PTSD

100
Q

scared straight

A

Seasoned inmates scare youth about consequences of criminality. This may increase conduct problems

101
Q

Recovered memories

A

Encouragement to ‘recover’ memories of trauma. This may lade to false memories being created

102
Q

boot camp

A

Delinquent youth attend military style camps. This may increase conduct problems

103
Q

potential harm of all therapies

A

All therapies have the potential for harm; biological, psychological and social therapies can have aversive or unintended effects; clients need to be informed of risks (known and unknown).

104
Q

Primary prevention

A

improve environments to prevent new cases of mental illness

105
Q

secondary prevention

A

early identification and intervention to prevent deterioration

106
Q

why do prevention models exist?

A

to promote wellbeing in
– Workplaces
– Schools
– Or more broadly in the community

107
Q

prevention rather than treatment?

A
  • Prevention studies yield some positive results with primary and secondary school groups (e.g.,Durlack & Wells, 1997)
  • Fair results noted in the general population
  • Effectiveness probably weakened when aimed at preventing symptoms not causes.
  • Generally most effective for anxiety, mood, and eating/sleep disorders
