Study information

Study design	Multicentre, randomised controlled trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Other
Study type	Treatment
Scientific title	A randomised controlled trial of cognitive therapy plus treatment as usual versus treatment as usual in the treatment of borderline personality disorder
Study acronym	BOSCOT
Study objectives	We anticipate that the addition of cognitive behavioural therapy to treatment as usual (CBT plus TAU) in participants with borderline personality disorder will decrease the number of participants with in-patient psychiatric hospitalisations or accident and emergency room contact or suicidal acts over twelve months treatment and twelve months follow-up, compared with treatment as usual (TAU). We also anticipate that CBT plus TAU will lead to superior improvement in quality of life, social, cognitive and mental health functioning compared to TAU alone.
Ethics approval(s)	Research Ethics Committee of Greater Glasgow Primary Care NHS Trust gave approval on the 15th August 2001
Health condition(s) or problem(s) studied	Borderline personality disorder
Intervention	Those participants who met the inclusion criteria and who agreed to give written informed consent to take part in the study then completed baseline assessments and were randomly allocated to either one of two active treatment groups namely, TAU, or CBT plus TAU. Interventions: CBT is a structured, time limited, psycho-social intervention which has been developed to treat those with Cluster B personality disorder. Patients are encouraged to engage in treatment through a formulation of their problems within a cognitive framework. Interventions focus on the patient's beliefs and behaviour that impair social and adaptive functioning. Up to 30 sessions (minimum 15) of treatment, each lasting up to one hour, are required to work on long-standing problems and develop new ways of thinking and behaving. Priority is given to behaviours that cause harm to self or others. In addition, participants received the usual treatment they would have received if the trial had not been in place. Treatment as usual: All participants received the standard treatment (TAU) they would have received if the trial had not been in place. It was thought that all participants would be in contact with mental health services and would have some contact with Accident and Emergency services for repeated self-harm episodes. TAU will be documented carefully after each patient exits the trial.
Intervention type	Other
Primary outcome measure	Acts of deliberate self-harm in the twelve months prior to baseline, and the twelve months following baseline. Trial participants are being assessed on all measures at six monthly intervals.
Secondary outcome measures	1. Brief Symptom Inventory 2. Beck Depression Inventory-II 3. State-Trait Anxiety Inventory 4. Social Functioning Questionnaire 5. Inventory of Interpersonal Problems 6. Schema Questionnaire 7. The Euro-Qol quality of life questionnaire 8. Client Service Receipt Inventory (CSRI) Trial participants are being assessed on all measures at six monthly intervals, except for the Schema Questionnaire and the Brief Symptom Inventory, where both are assessed at end of treatment and end of follow-up only.
