Lovell et al. (2006) Flashcards
Context
Weekly, in-person therapy is costly and lengthy waiting lists can make it inaccessible.
Aim and hypothesis
To compare telephone vs face-to-face ERP CBT treatment.
Telephone ERP is not less effective than face-to-face ERP.
Method
Randomised control trial, independent measures, longitudinal.
Participants
72 16-65 year-old outpatients with OCD from the UK.
All scored 16+ on the Y-BOCS and did not suffer from substance misuse or other conditions.
Sampling
Opportunity sample.
How were ppts assigned to each condition?
What were the conditions?
Randomly assigned to either the telephone or face-to-face condition (independent measures design).
Explain the sessions of CBT
Exposure response prevention therapy, either delivered traditionally through a 60-minute face-to-face session, or by a shorter telephone call (up to 30 minutes).
How many sessions were given to each ppt?
How often?
10 weekly sessions.
How many therapists carried out the treatments?
How was the consistency of treatment maintained?
2 experienced therapists (one at each clinic carried out both type).
Therapist manuals were used, alongside fortnightly supervision sessions and 4-monthly training days.
How were ppts assessed prior to treatment?
Prior to treatment, all ppts were assessed twice, 4 weeks apart, using the Y-BOCS to measure the severity of their OCD and BDI to measure feelings of depressive disorder.
How were ppts assessed after treatment?
Ppts were assesed using the Y-BOCS and BDI immediately following treatment, then at 1, 3 and 6-month follow-ups.
There were also given a client satisfaction questionnaire.
What was there no significant difference in between the groups before treatment or at any of the follow-up assessments?
No significant difference in symptom severity between the telephone and face-to-face groups.
Did client satisfaction differ?
Client satisfaction did not differ immediately after treatment.
For what percentage of ppts in each group was treatment successful for?
- Telephone group = 77%
- Face-to-face group = 67%
Conclusions
Telephone ERP CBT for OCD is as effective as face-to-face therapy, despite 50% less therapist contact time.
