Dosage effects of psychodynamic and schema therapy in people with comorbid depression and personality disorder: four-arm pragmatic randomised controlled trial

BACKGROUND

Higher intensity of psychotherapy might improve treatment outcome in depression, especially in those with comorbid personality disorder.

AIMS

To compare the effects of 25 individual sessions (weekly) of two forms of psychotherapy - short-term psychoanalytic supportive psychotherapy (SPSP) and schema therapy - with the same treatments given for 50 sessions (twice weekly) in people with depression and personality disorder. Trial registration: NTR5941.

METHOD

We conducted a pragmatic, double-randomised clinical trial and, over 37 months, recruited 246 adult out-patients with comorbid depression/dysthymia and personality disorder. A 2 × 2 factorial design randomised participants to 25 or 50 sessions of SPSP or schema therapy. The primary outcome was change in depression severity over 1 year on the Beck Depression Inventory II (BDI-II). Secondary outcomes were remission both of depression and personality disorder.

RESULTS

Compared with 25 sessions, participants who received 50 sessions showed a significantly greater decrease in depressive symptoms over time (time × session dosage, P < 0.001), with a mean difference of 5.6 BDI points after 1 year (d = -0.53, 95% CI -0.18 to 0.882, P = 0.003). Remission from depression was also greater in the 50-session group (74% v. 58%, P = 0.025), as was remission of personality disorder (74% v. 56%, P = 0.010).

CONCLUSIONS

Greater intensity of psychotherapy leads to better outcomes of both depression and personality status in people with comorbid depression and personality disorder.

Gender-specific pathways in mental health crisis in adolescents, from consultation to (in)voluntary admission: a retrospective study

BACKGROUND

A strong increase in mental health emergency consultations and admissions in youths has been reported in recent years. Although empirical evidence is lacking, gender differences in risk of admission may have contributed to this increase. A clearer understanding of the relationship, if any, between gender and various aspects of (in)voluntary care would help in more evidence-based service planning.

METHODS

We analysed registry data for 2008-2017 on 3770 outpatient emergencies involving young people aged 12 to 18 years from one urban area in the Netherlands, served by outreaching psychiatric emergency services. These adolescents were seen in multiple locations and received a psychosocial assessment including a questionnaire on the severity of their problems and living conditions. Our aims were to (a) investigate the different locations, previous use of mental health service, DSM classifications, severity items, living conditions and family characteristics involved and (b) identify which of these characteristics in particular contribute to an increased risk of admission.

RESULTS

In 3770 consultations (concerning 2670 individuals), more girls (58%) were seen than boys. Boys and girls presented mainly with relationship problems, followed by disruptive disorders and internalizing disorders. Diagnostic differences diminished in hospitalisation. More specifically, disruptive disorders were evenly distributed. Suicide risk was rated significantly higher in girls, danger to others significantly higher in boys. More girls than boys had recently been in mental health care prior to admission. Although boys and girls overall did not differ in the severity of their problems, female gender predicted admission more strongly. In both boys and girls severity of problems and lack of involvement of the family significantly predicted admission. Older age and danger to others significantly predicted admission among boys, whereas psychosis, suicidality and poor motivation for treatment predicted admission among girls.

CONCLUSION

There are different pathways for youth admission, which can partly be explained by different psychiatric classifications as well as gender-specific differences with regard to age, suicide risk, danger to others and the influence of motivation for treatment. Finally, for both genders, family desire for hospitalisation is also an important predictor.
