The impact of a novel computerized CBT CD-Rom (overcoming depression) offered to patients referred to clinical psychology

Abstract

Methods:

A new computerized cognitive behavioural therapy (CCBT) program was offered to consecutive referrals to the clinical psychology department where the referral letter had noted the presence of depression/low mood as a major problem. The exclusion criteria were age below 16 or above 65, current active suicidal intent, psychosis and an inability to read.

Results:

Seventy-eight consecutive referrals were offered an appointment for CCBT; 20 (26%) attended at least one session of CCBT and 14 (70% of starters) completed all six hour-long sessions. A clinically and statistically significant fall of over 11.07 points (SD 6.16) on the BDI-II occurred between baseline and 6 weeks, from a mean score of 30 (severe) to 18.93 (mild). The equivalent mean differences between the baseline and 6-week scores were 7.66 points for the BAI (SD 11.25), 2.93 points for the BHS (SD 5.54), and –3.93 points for the SASS (SD 8.35). Beck Depression Inventory scores (BDI-II) fell from a mean of 28.15 (SD 11.41) to 20.00 (SD 10.41) (p=.000) over the 6-week intervention period using an intention to treat analysis. The mean time with a self-help support nurse supporting their use of the CD Rom was 52 minutes in total.

Conclusion:

Only a quarter of patients on this psychology waiting list chose to use a CBT CD-Rom. The package seems to lead to improved mood. A randomised controlled study is required and is in progress.
