Knowing what predicts discontinuation or success of psychotherapies for Borderline Personality Disorder (BPD) is important to improve treatments. Many variables have been reported in the literature, but replication is needed and investigating what therapy process underlies the findings is necessary to understand why variables predict outcome. Using data of an RCT comparing Schema Therapy and Transference Focused Psychotherapy as treatments for BPD, variables derived from the literature were tested as predictors of discontinuation and treatment success. Participants were 86 adult outpatients (80 women, mean age 30.5 years) with a primary diagnosis of BPD who had on average received 3 previous treatment modalities. First, single predictors were tested with logistic regression, controlling for treatment type (and medication use in case of treatment success). Next, with multivariate backward logistic regression essential predictors were detected. Baseline hostility and childhood physical abuse predicted treatment discontinuation. Baseline subjective burden of dissociation predicted a smaller chance of recovery. A second study demonstrated that in-session dissociation, assessed from session audiotapes, mediated the observed effects of baseline dissociation on recovery, indicating that dissociation during sessions interferes with treatment effectiveness. The results suggest that specifically addressing high hostility, childhood abuse, and in-session dissociation might reduce dropout and lack of effectiveness of treatment.

Abstract Background: Although there is little evidence on their efficacy regarding challenging behaviour, antipsychotics are the most used psychotropic drugs in residential intellectually disabled people. Discontinuation is possible for some residential clients with intellectual disabilities. This study aimed to gain insight into support staff's perceptions of discontinuing antipsychotics in residential clients with intellectual disabilities. Method: Four focus groups were conducted in this mixed‐methods study, followed by a survey. Results: A large majority of support staff perceive antipsychotics to be effective in controlling challenging behaviour. Support staff regarded themselves as willing to contribute to the discontinuation of antipsychotics, but were more confident about achieving reductions. Conclusions: The attitude of the majority of support staff towards discontinuation provides a good basis for regularly reviewing antipsychotics use. A reduction plan should include preliminary steps, methods of monitoring and evaluating the process, and establishing measures for dealing with possible crises.

Introduction: Over the past decade, frequent use of large quantities of nitrous oxide (N2O) has become more common in the Netherlands. Although N2O poses several negative health consequences for a subgroup of problematic N2O users, there is a lack of knowledge on what characterizes these intensive users. This study therefore aims to provide the demographic and substance use characteristics and experiences during treatment of treatment seeking problematic N2O users and to compare this with a matched group of treatment-seeking problematic cocaine users. Methods: A retrospective chart review was performed of patients who were referred for treatment of problematic N2O use at a large Dutch addiction care facility from January 2020 to September 2022, extracting demographics, pattern of use and follow-up data. Additionally, a subgroup of N2O users was propensity-score matched (1:1) with a subgroup of treatment seeking problematic cocaine users, both groups excluding users with substance use disorders or frequent use of substances other than N2O and cocaine, respectively. Results: 128 patients with a N2O use disorder were included in the total sample and a subgroup of 77 N2O-only users was propensity-score matched on age and sex to 77 cocaine-only users. N2O users were typically young (mean age 26.2 years), male (66.4%), unmarried (82.9%), with a low education level (59.0%) and born in the Netherlands (88.2%), with parents born in Morocco (45.3%). N2O was used intermittently (median 10 days/month, IQR 4.0–17.5 days) and often in very large quantities (median 5 kg [ca. 750 balloons] per average using day, IQR 2–10 kg). Compared to the patients with a cocaine use disorder, matched N2O users were lower educated, more often from Moroccan descent, and less likely to be alcohol or polysubstance users. Despite receiving similar treatments, N2O users were twice as likely to discontinue treatment before completion compared to cocaine users (63 vs. 35%, p = 0.004). Conclusion: Treatment-seeking problematic N2O users are demographically different from treatment-seeking problematic cocaine users and are much more likely to dropout from psychological treatment. Further research is needed into the needs and other factors of problematic N2O users that relate to poor treatment adherence in problematic N2O users.
