Psychological therapy for mood instability within bipolar spectrum disorder: a single-arm feasibility study of a dialectical behaviour therapy-informed approach.

ABSTRACT: Background:We sought to evaluate the acceptability of a psychological therapy programme (Therapy for Inter-episode Mood Variability in Bipolar Disorder (ThrIVe-B)) for individuals with ongoing bipolar mood instability and the feasibility and acceptability of potential trial procedures. We also evaluated the performance of clinical and process outcome measures and the extent to which the programme potentially represents a safe and effective intervention. Method:We conducted an open (uncontrolled) trial in which 12 individuals with a bipolar spectrum diagnosis commenced the ThrIVe-B programme after completing baseline assessments. The programme comprised 16 group skills training sessions plus individual sessions and a supporting smartphone application. Follow-up assessments were at therapy end-point and 6?months post-treatment. Results:Nine participants completed treatment. Ten provided end-of-treatment data; of these, nine were satisfied with treatment. Interviews with participants and clinicians indicated that the treatment was broadly feasible and acceptable, with suggestions for improvements to content, delivery and study procedures. Exploration of change in symptoms was consistent with the potential for the intervention to represent a safe and effective intervention. Conclusions:Conducting further evaluation of this approach in similar settings is likely to be feasible, whilst patient reports and the pattern of clinical change observed suggest this approach holds promise for this patient group. Future research should include more than one study site and a comparison arm to address additional uncertainties prior to a definitive trial. Trial registration:Trial Registration: ClinicalTrials.gov NCT02637401; registered 22.12.15 (retrospectively registered).

Project description:BackgroundA subgroup of those with bipolar spectrum disorders experience ongoing mood fluctuations outside of full episodes. We conducted a randomised, controlled feasibility study of a Dialectical Behavioural Therapy-informed approach for bipolar mood fluctuations (Therapy for Inter-episode mood Variability in Bipolar [ThrIVe-B]). Our study aimed to examine the feasibility and acceptability of a future definitive trial evaluating the clinical and cost effectiveness of the ThrIVe-B programme. Participants were required to meet diagnostic criteria for a bipolar spectrum disorder and report frequent mood swings outside of acute episodes. They were randomised to treatment as usual (control arm) or the ThrIVe-B intervention plus treatment as usual (intervention arm). Follow-up points were at 3, 6, 9 and 15 months after baseline, with 9 months as the primary end point. To evaluate feasibility and acceptability we examined recruitment and retention rates, completion rates for study measures, adverse events and feedback from participants on their experience of study participation and therapy.ResultsOf the target 48 participants, 43 were recruited (22 in the intervention arm; 21 in the control arm), with a recruitment rate of 3.9 participants per month. At 9 months 74% of participants engaged in research follow-up assessment, exceeding the pre-specified criterion of 60%. There were no serious concerns about the safety of the research procedures or the intervention. On one of the four candidate primary outcome measures, the 95% CI for the between-group mean difference score excluded the null effect and included the minimal clinically important difference, favouring the intervention arm, whilst on no measure was there evidence of deterioration in the intervention arm relative to the control arm. Attendance of the intervention (50% attending at least half of the mandatory sessions) was below the pre-specified continuation criterion of 60%, and qualitative feedback from participants indicated areas that may have hampered or facilitated engagement.ConclusionsIt is broadly feasible to conduct a trial of this design within the population of people with frequent bipolar mood swings. Changes should be made to the therapy to increase uptake, such as simplifying content and considering individual rather than group delivery. Trial registration ISRCTN: ISRCTN54234300.

Project description:BackgroundRadically Open Dialectical Behaviour Therapy (RO DBT) is a novel transdiagnostic treatment that targets 'maladaptive overcontrol'; a transdiagnostic cluster of traits associated with excessive emotional and behavioural inhibitory control. Outcomes are promising for adults with a range of psychiatric disorders. No study to date has explored the adolescent experience of RO DBT.MethodsOf the 25 eligible adolescents who received RO DBT between March 2015 and April 2017, 15 (14-17 years) consented and completed a semi-structured interview about their experience of treatment within 1 month of discharge. Interviews were recorded and then transcribed manually. Free text responses were analysed using reflexive thematic analysis.ResultsThe majority (n = 13) had a primary diagnosis of anorexia nervosa, although comorbidity was the norm, with 80.0% having two or more predicted comorbid psychiatric diagnoses. All had received some prior psychological treatment. Four themes were identified from analysis of transcripts: 1) Broadening Horizons, 2) Building Connections, 3) Flexibility, 4) Information Overload. Generally, RO DBT was perceived as helpful in both content and process. The focus on social and broader well-being, rather than specific mental health symptoms, was considered beneficial by many. Adolescents appreciated the group-based format of skills classes and reported benefiting from learning and practicing skills each week. The fourth theme, Information Overload, highlighted that for some, the amount of content felt overwhelming and that it was hard to remember and digest all the information, suggesting that adaptations, or simplifications, may be required to ensure accessibility for adolescents.ConclusionsRO DBT is perceived as a relevant and beneficial new treatment for adolescents with maladaptive overcontrol. The broad treatment focus is perceived as unique and of particular benefit. It is reported to help with general and social functioning and foster cognitive and behavioural flexibility. Nevertheless, the amount and complexity of material was felt to be very large by some and may suggest the need for modified adolescent-specific materials.

Project description:BackgroundBorderline personality disorder (BPD) is a mental health condition characterized by an inability to regulate emotions or accurately process the emotional states of others. Previous neuroimaging studies using classical univariate analyses have tied such emotion dysregulation to aberrant activity levels in the amygdala of patients with BPD. However, multivariate analyses have not yet been used to investigate how representational spaces of emotion information may be systematically altered in patients with BPD.MethodsPatients with BPD performed an emotional face matching task while undergoing MRI before and after a 10-week inpatient program of dialectical behavioural therapy. Representational similarity analysis (RSA) was applied to activity patterns (evoked by angry, fearful, neutral and surprised faces) in the amygdala and temporo-occipital fusiform gyrus of patients with BPD and in the amygdala of healthy controls.ResultsWe recruited 15 patients with BPD (8 females, 6 males, 1 transgender male) to participate in the study, and we obtained a neuroimaging data set for 25 healthy controls for a comparative analysis. The RSA of the amygdala revealed a negative bias in the underlying affective space (in that activity patterns evoked by angry, fearful and neutral faces were more similar to each other than to patterns evoked by surprised faces), which normalized after therapy. This bias-to-normalization effect was present neither in activity patterns of the temporo-occipital fusiform gyrus of patients nor in amygdalar activity patterns of healthy controls.LimitationsLarger samples and additional questionnaires would help to better characterize the association between specific aspects of therapy and changes in the neural representational space.ConclusionOur findings suggest a more refined role for the amygdala in the pathological processing of perceived emotions and may provide new diagnostic and prognostic imaging-based markers of emotion dysregulation and personality disorders.Clinical trial registration: DRKS00019821, German Clinical Trials Register (Deutsches Register Klinischer Studien).
