Study information

Scientific title

(Cost)effectiveness of a cognitive group prevention module for recurrent depression


Study hypothesis

Our primary hypothesis was that in remitted patients with recurrent depression, augmenting treatment as usual (TAU) with cognitive therapy (CT) would reduce and/or postpone relapse/recurrence. In view of Teasdale's findings (et al., 2000), we expected this effect to be moderated by the number of previously experienced depressed episodes. As secondary hypotheses, we expected that augmenting treatment as usual with CT would also reduce the severity of a depressive episode, and the number of times a patient would have a relapse/recurrence. Finally, an exploratory aim of the study was to analyze differences in demographic, clinical and psychological characteristics between patients below or above the reversal point for number of previous depressive episodes needed for potential benefit from CT.

Cognitive therapy (CT). The CT in the experimental condition involved eight weekly two-hour sessions. As in other prevention studies (Ma & Teasdale, 2004; Teasdale et al., 2000) a group format was chosen, for cost-effectiveness reasons but also because we were dealing with a patient group without current psychopathology. More specifically, we used a closed format with a mean membership of 8 (7 to 12 members). Each CT session followed a fixed structure, with agenda setting, review of homework, explanation of rationale of each session, and assignment of homework. Nine specifically trained psychologists (one of them was the principal investigator) delivered the prevention module; all were fully trained cognitive behavior therapists (minimum of 5 years of training). Before conducting the experimental groups, each therapist received 16 hours of additional specific training. A treatment manual (available on request from first author) was used and regular supervision was provided. All intervention group sessions were audiotaped to enable treatment integrity to be evaluated, using a checklist of all particular interventions. Any adherence or competence issues were resolved with the therapist prior to the subsequent session (in fact only one instance: an overlooked homework assignment).
The CT was focused mainly on identification and change of dysfunctional attitudes. Unlike CT for acutely depressed patients (Beck, 1987; Beck, Rush, Shaw, & Emery, 1979), the present module was not primarily directed toward modifying negative thoughts. Instead, it started with the identification of negative thoughts (Session 1) and dysfunctional attitudes, aided by a self report questionnaire with examples of attitudes and techniques such as vertical arrow technique (Sessions 1-3), and then proceeded to focus on changing of these attitudes using different cognitive techniques such as Socratic questioning and identification of positive attitudes (Sessions 3-7). Moreover, patients were encouraged to practice with alternative attitudes (Sessions 6-8). In contrast with the preventive program of Teasdale and colleagues (2000), involving additional meditation interventions were used, solely cognitive interventions were used in the present study, concentrated on change of content. Several studies have found that in comparison with normal controls acutely depressed patients have a tendency to retrieve more overgeneral autobiographical memories on a cue-word task (i.e. more generic memories of past events rather than specific memories referring to a particular event happening on a particular time and place [Goddard, Dritschel & Burton, 1996; Williams & Scott, 1988]). This inability to retrieve specific memories from the past is associated with impaired problem-solving skills (Pollock & Williams, 2001), long-term course of depressive disorders (Peeters, Wessel, Merkelbach, & Boon-Vermeeren, 2002) and difficulties in recovering from depression (Brittlebank, Scott, Williams, & Ferrier, 1993). Unlike with traditional acute CT, patients were asked to keep a diary of positive experiences in order to enhance specific memories of positive experiences, instead of retaining overgeneral memories. (sessions 4-6). Further specific relapse/recurrence prevention strategies were formulated in the last three sessions.

Primary outcome measures

Relapse/recurrence: To assess relapse/recurrence, we used the Structured Clinical Interview for DSM-IV (SCID-I; First, Gibbon, Spitzer, & Williams, 1996). At baseline and at three follow-up assessments (3, 12, and 24 months), current and past depressive episodes were checked.

Secondary outcome measures

The number of relapse/recurrence and severity of relapse/recurrence
