Individual psychotherapy for cluster-C personality disorders: protocol of a pragmatic RCT comparing short-term psychodynamic supportive psychotherapy, affect phobia therapy and schema therapy (I-FORCE)

BACKGROUND

Cluster-C personality disorders (PDs) are highly prevalent in clinical practice and are associated with unfavourable outcome and chronicity of all common mental health disorders (e.g. depression and anxiety disorders). Although several forms of individual psychotherapy are commonly offered in clinical practice for this population, evidence for differential effectiveness of different forms of psychotherapy is lacking. Also, very little is known about the underlying working mechanisms of these psychotherapies. Finding evidence on the differential (cost)-effectiveness for this group of patients and the working mechanisms of change is important to improve the quality of care for this vulnerable group of patients.

OBJECTIVE

In this study, we will compare the differential (cost)-effectiveness of three individual psychotherapies: short-term psychodynamic supportive psychotherapy (SPSP), affect phobia therapy (APT) and schema therapy (ST). Although these psychotherapies are commonly used in clinical practice, evidence for the Cluster-C PDs is limited. Additionally, we will investigate predictive factors, non-specific and therapy-specific mediators.

METHODS

This is a mono-centre randomized clinical trial with three parallel groups: (1) SPSP, (2) APT, (3) ST. Randomization on patient level will be pre-stratified according to type of PD. The total study population to be included consists of 264 patients with Cluster-C PDs or other specified PD with mainly Cluster-C traits, aged 18-65 years, seeking treatment at NPI, a Dutch mental health care institute specialized in PDs. SPSP, APT and ST (50 sessions per treatment) are offered twice a week in sessions of 50 min for the first 4 to 5 months. After that, session frequency decreases to once a week. All treatments have a maximum duration of 1 year. Change in the severity of the PD (ADP-IV) will be the primary outcome measure. Secondary outcome measures are personality functioning, psychiatric symptoms and quality of life. Several potential mediators, predictors and moderators of outcome are also assessed. The effectiveness study is complemented with a cost-effectiveness/utility study, using both clinical effects and quality-adjusted life-years, and primarily based on a societal approach. Assessments will take place at baseline, start of treatment and at 1, 3, 6, 9, 12, 18, 24 and 36 months.

DISCUSSION

This is the first study comparing psychodynamic treatment to schema therapy for Cluster-C PDs. The naturalistic design enhances the clinical validity of the outcome. A limitation is the lack of a control group for ethical reasons.

"I'm not here to push you:" raising adolescents' treatment engagement via autonomy support

More than 45% of adolescents with aggressive behavior problems drop out of treatment prematurely. Building on insights from self-determination theory, we examined in three studies whether clinicians can raise adolescents' treatment engagement by supporting their autonomy. In an interview study (Study 1), clinicians (N = 16; 43.8% female; ages 30-57) spontaneously described 12 times more autonomy-supportive than controlling strategies to engage adolescents. In a preregistered experiment (Study 2), clinicians (N = 68; 88.2% female; ages 23-65) were confronted with videos of adolescents displaying resistance. We manipulated the DSM diagnosis of adolescents to indicate either aggressive behavior problems or other problems. We found that, regardless of diagnosis, clinicians used both autonomy-supportive strategies (57.7% of responses) and controlling strategies (39.3%), suggesting that applying autonomy support can be challenging with any adolescent displaying resistance. In an experimental study (Study 3), adolescents (N = 252; 50.0% female; ages 12-17) reported higher therapeutic alliance (d = 0.95, 95% CI [0.80, 1.10]) and treatment engagement (d = 0.77, 95% CI [0.63, 0.91]) after listening to audio-recorded autonomy-supportive versus controlling responses from clinicians, regardless of whether these adolescents had aggressive behavior problems. Overall, this research suggests that clinicians can raise adolescents' treatment engagement through autonomy support.

Psychological intervention in patients with advanced cancer at home through Individual Meaning-Centered Psychotherapy-Palliative Care: a pilot study

OBJECTIVE

To compare Individual Meaning-Centered Psychotherapy-Palliative Care (IMCP-PC) to counselling-based psychotherapy in patients receiving home palliative care (PC).

METHODS

Fifty-one patients with advanced-stage cancer receiving home PC were recruited for this. Two-arm (individual meaning-centered psychotherapy-palliative-IMCP-PC-care vs. counselling) randomized feasibility trial. Anxiety, depression, demoralization, and emotional distress were evaluated before and after three psychotherapy sessions. Patient perceptions of the treatment were assessed after completion of therapy.

RESULTS

Thirty-two patients (16 in each group) completed all three sessions as well as the pre- and post-therapy questionnaires and were therefore included in the final analysis. All patients in the IMCP-PC group showed a significant decrease in levels of demoralization (despair), anxiety, depression, and emotional distress. By contrast, the only variable that significantly improved in the counselling group was demoralization. The post-treatment questionnaire revealed no significant between-group differences regarding patient perception of the structure, focus, or length of treatment. However, the IMCP-PC group rated the treatment more highly with regard to its value in helping them to find meaning in life.

CONCLUSIONS

IMCP-PC is a specific psychotherapy tailored to the needs of patients with advanced cancer. The results of the present study indicate that this treatment is suitable for patients at end of life that are not able to attend outpatient sessions. Although more research is needed, the findings of this feasibility trial suggest that the IMCP-PC merits consideration for patients receiving home palliative care (PC).

Pharmacotherapy and group cognitive behavioral therapy enhance follow-up treatment duration in gambling disorder patients

BACKGROUND

Longer treatment duration is important for the successful treatment of gambling disorder (GD). This retrospective study investigated the factors and interventions that might enhance treatment duration in GD patients in South Korea.

METHODS

A total of 758 outpatients with a primary diagnosis of GD, who were treated in a clinical practice from 2002 to 2011, were assessed by retrospective chart review. We compared the treatment duration according to pharmacotherapy and group cognitive behavioral therapy (CBT).

RESULTS

Pharmacotherapy contributed to a longer duration of treatment maintenance, despite the patients' gambling severity (p < 0.001). Participation in group CBT (p < 0.001) and antidepressants (p = 0.009) were associated with a longer treatment duration after adjusting for age, depression, and gambling severity. The treatment maintenance duration was the longest in those receiving combined antidepressant pharmacotherapy and group CBT (F = 35.79, p < 0.001).

CONCLUSIONS

Group CBT and antidepressants seem to enhance treatment follow-up duration in GD patients. Additional studies are needed to advance GD prevention and treatment strategies.

A web-based self-management intervention for Bipolar Disorder 'living with bipolar': a feasibility randomised controlled trial

BACKGROUND

Bipolar Disorder (BD) is a severe mental health problem. Psychological interventions are recommended by the National Institute for Health and Care Excellence (NICE) but patients experience severe inequalities in access. This study assessed the feasibility and potential effectiveness of a recovery informed web-based self-management intervention for people with BD.

METHODS

An online randomised controlled trial (n=122) compared treatment as usual (TAU) plus the 'Living with Bipolar' (LWB) intervention with a waiting list control (WLC) group.

RESULTS

The study recruited to target and the retention rates were high. Participants engaged with the approach. Compared with the WLC, those receiving LWB showed the most robust improvement in psychological and physical domains of quality of life, wellbeing and recovery at the end of the intervention.

LIMITATIONS

The trial was not definitive and requires further investigation.

CONCLUSIONS

There is preliminary evidence that a web-based treatment approach in BD is feasible and potentially effective. Such interventions could form part of the Improving Access to Psychological Therapy (IAPT) initiative in severe mental health.
