Elkin et al - CBT not suitable for individuals with high levels of emotional beliefs that are rigid and hesitant to change.
Simons et al - less suitable in situations where high levels of stress reflect on realistic stressors in the person’s life that therapy cannot resolve.
Ellis - some people just want to share their story with a therapist without the cognitive effort associated with recovery
support for behavioural activation
Babyak et al - 156 adult volunteers diagnosed with major depressive disorder. randomly assign to 4 month course of aerobic exercise, drug treatment, or a combination of the two.
clients in all three groups exhibited significant improvement at the end of the 4 months. six months after, exercise groups had significantly lower relapse rates than medicine group.
alternative treatments
antidepressants such as SSRI. drug therapies require less effort from client and can be used i conjunction with psychotherapy like CBT.
useful because distressed client may be unable to focus on the demands of CBT. drug treatment could enable them to cope better
“Dodo bird effect”
Rosenzweig - Dodo bird in ‘Alice in Wonderland’ who suggested everyone should win.
lack of differences between therapies because they have common factors; talking to a sympathetic person and having an opportunity to express one’s thoughts (Sloane et al)
