Flashcards in Psychological therapies for depression Deck (19):
When was CBT first developed?
Whats the aim of CBT?
identify and alter maladaptive cognitions and therefore change dysfunctional behaviour
What does CBT focus on?
How long does CBT last for?
Individuals are taught the link between their behaviour and their thoughts. As homework they may be asked to record emotion-arousing events, record their initial negative thoughts on it, and then a realistic thought which could challenge this, for example ‘where is the evidence for this?’ ‘why does it matter?’. By challenging the dysfunctional thoughts and replacing them with more constructive ones, clients are trying out new ways of behaving.
Whats behavioural activation?
One characteristic of depression is that they no longer participate in activities they previously found pleasurable. In CBT the therapist and client identify potentially pleasurable activities and anticipate and deal with possible cognitive obstacles.
Effectiveness of CBT: research support
a meta-analysis by Robinson et al (1990) found that CBT was superior to non-treatment control groups, however wasn’t significantly more effective than a placebo group.
Effectiveness of CBT: depression and exercise
Babyak et al (2000) studied 156 adult volunteers diagnosed with major depressive disorder. They were randomly assigned to a four-month course of aerobic exercise, drug treatment, or a combination of the 2. All 3 groups experienced significant improvement. However 6 months later the exercise group had significantly lower relapse rates, particularly those who had continued to exercise on their own.
Effectiveness of CBT: importance of homework
Brayant et al (1999) suggests that client’s engagement with homework predicts the outcome.
Appropriateness of CBT: who its suitable for
March et al found that in a group of 327 adolescents aged 12-17 that CBT combined with drug therapy had a significantly better outcome than drug therapy along. CBT also significantly reduced suicidal thoughts.
CBT can also be conducted over the phone which helps reduce attrition rates and makes it more accessible.
Appropriateness of CBT: who it isnt suitable for
unsuitable for people resistant to change, or when stress reflects real stressors in a person’s life which therapy cannot resolve?
When was PIT first developed?
Robert Hobson 1985
What does PIT talk about?
past and present events
Whats the importance of the relationship?
Hobson believed symptoms of depression can arise from disturbances in interpersonal relationships and these can only be explored within another relationship.
the quality of the relationship is crucial
Effectiveness of PIT: research support
Paley et al (2008) showed CBT to be at least equal to PIT. However, they didn’t consider life changes and therefore the outcomes might not be just due to the therapy. (62 ps over a 52 month period)
Effectiveness of PIT: Collaborative psychotherapy project (CPP)
Barkham et al (1996) found that PIT and CBT were equally effective in reducing the severity of depression (measured with BDI). But after 12 months both groups experienced relapse.
Effectiveness of PIT: attrition
Hunt and Andrews (2007) examined 5 meta-analysis and found that an average of 8% of ps drop out of studies because it isn’t helping. Therefore the results are only based on ps who feel it is helping; making them artificially high.
Appropriateness of PIT: importance of relationships
Guthrie (1999) suggested pit is particularly important as it focuses on interpersonal relationships which other cognitive therapies ignore. As a result the quality of the relationships has shown to determine the outcome of the therapy.
