Lack of Control Group

Question 1

Rodriguez (2009)

Answer 1

Investigated the effectiveness of CBT on BD and stated that it provided many benefits such as helping to reduce negative symptoms and encourage personal growth, which allows patients to commit to treatment. They reported that CBT improved adherence to medication.

Question 2

Rodriguez (2009) - trustworthy?

Answer 2

As there was no control group, it cannot be concluded whether the results were due to CBT alone, as the results could be attributed to other factors. Some individuals may struggle with treatment due to the nature of their discarded and thus, a control group is beneficial to allow for individual differences.

Question 3

Scott et. al (2006) - nature of disorder

Answer 3

Reported that individuals with greater than 12 episodes did not respond well to treatment and may have deteriorated. It was reported that when being monitored, those with BD experienced ‘subsyndromal symptoms’.

Question 4

Scott et al - trustworthy?

Answer 4

The sample used did include individuals who are particularly prone to recurrence, thus the sample may not be representative.
