Despite the major advances in the development of treatments for bulimia nervosa, drop-outs and a lack of engagement in treatment, continue to be problems. Recent studies suggest that the transtheoretical model of change may be applicable to bulimia nervosa. The aim of this study was to examine the roles of readiness to change and therapeutic alliance in determining engagement and outcome in the first phase of treatment. One hundred and twenty five consecutive female patients meeting DSM-IV criteria for bulimia nervosa took part in a randomised controlled treatment trial. The first phase of the sequential treatment compared four sessions of either cognitive behavioural therapy (CBT) or motivational enhancement therapy (MET) in engaging patients in treatment and reducing symptoms. Patients in the action stage showed greater improvement in symptoms of binge eating than did patients in the contemplation stage. Higher pretreatment scores on action were also related to the development of a better therapeutic alliance (as perceived by patients) after four weeks. However, pretreatment stage of change did not predict who dropped out of treatment. There were no differences between MET and CBT in terms of reducing bulimic symptoms or in terms of developing a therapeutic alliance or increasing readiness to change. The results suggest that the transtheoretical model of change may have some validity in the treatment of bulimia nervosa although current measures of readiness to change may require modification. Overall, readiness to change is more strongly related to improvement and the development of a therapeutic alliance than the specific type of treatment.

The present study investigated the impact of pre-existing pharmacotherapy regimes on the long-term outcome of brief intensive group cognitive-behavioural therapy (BIGCBT) in the treatment of panic disorder with or without agoraphobia in 106 patients (74 females). Forty patients were allocated to BIGCBT without medication, 40 to BIGCBT plus anti-anxiety medication, 10 to BIGCBT plus anti-depressant medication and 16 to BIGCBT plus combined anti-anxiety and anti-depressant medications. The mean follow-up period was 3.2 yr and ranged from 1.1 to 6.2 yr. The results demonstrated that patients who received BIGCBT concurrent with pre-existing medication regimes did not differ significantly (P > 0.001) from each other or from patients who underwent BIGCBT without medication on any of the dependent measures either at pre-treatment assessment or long-term follow-up. However, BIGCBT (with or without pharmacotherapy) was associated with significant (P < 0.001) long-term improvements in frequency of panic attacks, avoidance behaviour and questionnaire measures of anxiety, depression and agoraphobia. Furthermore, the large majority (80%) of patients in the BIGCBT without medication group remained medication-free at long-term follow-up. Of those patients who underwent BIGCBT concurrent with pre-existing pharmacotherapy, a large percentage (44%) reported no longer taking medication for their condition at long-term follow-up. Overall, it is concluded that pre-existing medication regimes (anti-anxiety, anti-depressant or combinations of these) do not significantly enhance or detract from the long-term outcome of a BIGCBT program used in the treatment of panic disorder and agoraphobia.

Forty-six patients with spider phobia, fulfilling the DSM-IV criteria for specific phobia, were assessed with behavioral, physiological and self-report measures. They were randomly assigned to three group treatment conditions: (1) direct treatment; (2) direct observation; and (3) indirect observation. All treatments were carried out in large groups of eight patients, and consisted of one 3 hr session of massed exposure and modelling. The results showed that on the behavioral test, measures and the specific self-report measures of spider phobia the direct treatment was significantly better than direct observation and indirect observation, which did not differ. On the physiological measures and the psychopathology self-report measures there were significant pre-post improvements, but no differences between the groups. The effects were maintained or furthered at the one year follow-up assessment. The proportion of clinically significantly improved patients were, at post-treatment, 75% in the direct treatment, 7% in the direct observation, and 31% in the indirect observation group. At follow-up, the corresponding figures were 75, 14, and 44%, respectively. The conclusion that can be drawn is that direct treatment is the treatment of choice.
