People with borderline personality disorder frequently experience crises.
To date, no randomised controlled trials (RCTs) of crisis interventions
for this population have been published.
To examine the feasibility of recruiting and retaining adults with
borderline personality disorder to a pilot RCT investigating the
potential efficacy and cost-effectiveness of using a joint crisis
An RCT of joint crisis plans for community-dwelling adults with
borderline personality disorder (trial registration: ISRCTN12440268). The
primary outcome measure was the occurrence of self-harming behaviour over
the 6-month period following randomisation. Secondary outcomes included
depression, anxiety, engagement and satisfaction with services, quality
of life, well-being and cost-effectiveness.
In total, 88 adults out of the 133 referred were eligible and were
randomised to receive a joint crisis plan in addition to treatment as
usual (TAU; n=46) or TAU alone (n=42).
This represented approximately 75% of our target sample size and
follow-up data were collected on 73 (83.0%) participants.
Intention-to-treat analysis revealed no significant differences in the
proportion of participants who reported self-harming (odds ratio (OR)
=1.9, 95% CI 0.53-6.5,P = 0.33) or the frequency of
self-harming behaviour (rate ratio (RR)=0.74, 95% CI 0.34-1.63,
P=0.46) between the two groups at follow-up. No
significant differences were observed between the two groups on any of
the secondary outcome measures or costs.
It is feasible to recruit and retain people with borderline personality
disorder to a trial of joint crisis plans and the intervention appears to
have high face validity with this population. However, we found no
evidence of clinical efficacy in this feasibility study.
