âEveryone should do itâ: Client experience of a 12-week dialectical behaviour therapy group programme â An interpretative phenomenological analysis
Objective: There is a dearth of practice-based evidence of adapted or âDBTinformedâ
transdiagnostic models, which could provide services and
clinicians with information of what works and for whom, in which
settings. This paper aims to bridge this gap by exploring the client
experience of a 12-week transdiagnostic dialectical behaviour therapy
(DBT) group programme in a private psychiatric hospital. Method: Five
participants with varied clinical diagnoses and previous therapeutic
experiences were interviewed following completion of one or more of the
same adapted DBT programme, comprising of the standard four modules
over 12 weeks, including a weekly skills group and 1:1 therapy.
Interpretative phenomenological analysis (IPA) was applied to give voice
to the clientsâ lived experience of the group. Results: Three master themes
were identified: âPre DBT: Crisis & Desperationâ; âIn-session: Belongingâ;
and âThe Real World: Livingâ, each characterised by four sub-themes,
highlighting helpful and hindering factors of clientsâ current and previous
therapeutic experiences. Conclusion: Overall this version of DBT in a
transdiagnostic setting was experienced as helpful and positive by
participants; main outcomes included being able to build a life worth
living, feel hope and joy, build DBT skills into a lifestyle, and develop
reflective practice. Implications for clinical practice, service delivery and
policy are also discussed. The article aims to provide clinicians with
practice-based evidence to inform the delivery of DBT as well as
supporting the case for the use of DBT with various disorders, thus paving
the way for future research in this area
Little groups of irreps of O(3), SO(3), and the infinite axial subgroups
Little groups are enumerated for the irreps and their components in any basis
of O(3) and SO(3) up to rank 9, and for all irreps of C, C, C, D and D. The results are obtained
by a new chain criterion, which distinguishes massive (rotationally
inequivalent) irrep basis functions and allows for multiple branching paths,
and are verified by inspection. These results are relevant to the determination
of the symmetry of a material from its linear and nonlinear optical properties
and to the choices of order parameters for symmetry breaking in liquid
crystals.Comment: 28 pages and 3 figure
Early maladaptive schemas and borderline personality disorder features in a nonclinical sample : a network analysis
Borderline personality disorder (BPD) is a challenging problem. Early maladaptive schemas (EMSs) are considered as important vulnerability factors for the development and maintenance of BPD. Literature suggests a complex relationship between BPD and EMSs. The current study employed network analysis to model the complex associations between central BPD features (i.e., affective instability, identity problems, negative relations, and self-harm) and EMSs in 706 undergraduate students. The severity of BPD symptoms was assessed using the Personality Assessment Inventory-Borderline subscale; the Young Schema Questionnaire-Short Form was used to assess EMSs. Results suggest that specific EMSs show unique associations with different BPD features. Interestingly, affective instability showed no unique associations with EMSs. Identity problems were uniquely associated with abandonment, insufficient self-control, dependence/incompetence, and vulnerability to harm/illness schemas. Negative relations in BPD showed unique connections with mistrust/abuse and abandonment. Finally, BPD self-harm was connected to emotional deprivation and failure. These findings indicate potential pathways between EMSs and specific BPD features that could improve our understanding of BPD theoretically and clinically
Experimental investigation of the initial regime in fingering electrodeposition: dispersion relation and velocity measurements
Recently a fingering morphology, resembling the hydrodynamic Saffman-Taylor
instability, was identified in the quasi-two-dimensional electrodeposition of
copper. We present here measurements of the dispersion relation of the growing
front. The instability is accompanied by gravity-driven convection rolls at the
electrodes, which are examined using particle image velocimetry. While at the
anode the theory presented by Chazalviel et al. describes the convection roll,
the flow field at the cathode is more complicated because of the growing
deposit. In particular, the analysis of the orientation of the velocity vectors
reveals some lag of the development of the convection roll compared to the
finger envelope.Comment: 11 pages, 15 figures, REVTEX 4; reference adde
Outcomes for 18 to 25-year-olds with borderline personality disorder in a dedicated young adult only DBT programme compared to a general adult DBT programme for all ages 18
Aim
Targeting young adults with borderline personality disorder (BPD) for treatment may carry significant social and clinical benefits. We aimed to evaluate a communityâbased Dialectical Behaviour Therapy (DBT) programme delivered exclusively to young adults with BPD.
Methods
We describe a naturally occurring nonâequivalent, quasiâexperimental comparison of outcomes for young adults (18â25âyears) with BPD following 1 year of treatment in either a young adult only DBT programme or a general adult DBT programme (18+ years). Twentyâfour young adults enrolled in a communityâbased young adult DBT programme open only to 18â to 25âyearâolds with BPD. Another 13 young adults, also 18â25âyears, enrolled in a general adult DBT programme open to all ages above 18âyears. Both treatment conditions offered all modes of standard DBT for 1 year. Participants completed a battery of selfâreport measures on mental health symptoms at baseline and again at treatment completion after 1 year. Discharge rates at 2 years postâtreatment completion were also recorded.
Results
Better outcomes were found on borderline symptom severity and general psychopathology among completers of young adult DBT, with a large effect size for treatment condition as well as greater clinically significant change. Discharge rates from mental health services 24âmonths later were also higher for completers of young adult DBT.
Conclusions
There may be advantages in delivering DBT to young adults in an ageâspecific programme, possibly due to group cohesion. Methodological limitations apply, such as small sample size and nonârandomization. Further controlled research is needed
Early stages of ramified growth in quasi-two-dimensional electrochemical deposition
I have measured the early stages of the growth of branched metal aggregates
formed by electrochemical deposition in very thin layers. The growth rate of
spatial Fourier modes is described qualitatively by the results of a linear
stability analysis [D.P. Barkey, R.H. Muller, and C.W. Tobias, J. Electrochem.
Soc. {\bf 136}, 2207 (1989)]. The maximum growth rate is proportional to
where is the current through the electrochemical cell,
the electrolyte concentration, and . Differences
between my results and the theoretical predictions suggest that
electroconvection in the electrolyte has a large influence on the instability
leading to ramified growth.Comment: REVTeX, four ps figure
Chasing Clarity: Rumination as a Strategy for Making Sense of Emotions
Research is needed on the affective mechanisms that motivate people to ruminate. One possibility is that some people might ruminate in response to deficits in emotional clarity because not knowing how they feel might be intolerable to them. We tested the hypothesis that the relationship between low emotional clarity and rumination would be moderated by intolerance of ambiguity. Participants in a longitudinal online study (N = 195) provided self- reports of intolerance of ambiguity and rumination and reported state emotional clarity following an idiographic mood induction; three weeks later they reported on rumination again. As predicted, participants with low emotional clarity at Time 1 ruminated more three weeks later, but only if they were intolerant of ambiguity. Findings support the notion that rumination sometimes functions as a search for answers about emotions. We discuss implications for understanding the affective disturbances perpetuating vicious cycles of rumination and for rumination-focused clinical interventions

Phenotypic heterogeneity and genetic modification of P102L inherited prion disease in an international series
The largest kindred with inherited prion disease P102L, historically Gerstmann-StrÀussler-Scheinker syndrome, originates from central England, with émigrés now resident in various parts of the English-speaking world. We have collected data from 84 patients in the large UK kindred and numerous small unrelated pedigrees to investigate phenotypic heterogeneity and modifying factors. This collection represents by far the largest series of P102L patients so far reported. Microsatellite and genealogical analyses of eight separate European kindreds support multiple distinct mutational events at a cytosine-phosphate diester-guanidine dinucleotide mutation hot spot. All of the smaller P102L kindreds were linked to polymorphic human prion protein gene codon 129M and were not connected by genealogy or microsatellite haplotype background to the large kindred or each other. While many present with classical Gerstmann-StrÀussler-Scheinker syndrome, a slowly progressive cerebellar ataxia with later onset cognitive impairment, there is remarkable heterogeneity. A subset of patients present with prominent cognitive and psychiatric features and some have met diagnostic criteria for sporadic Creutzfeldt-Jakob disease. We show that polymorphic human prion protein gene codon 129 modifies age at onset: the earliest eight clinical onsets were all MM homozygotes and overall age at onset was 7 years earlier for MM compared with MV heterozygotes (P = 0.02). Unexpectedly, apolipoprotein E4 carriers have a delayed age of onset by 10 years (P = 0.02). We found a preponderance of female patients compared with males (54 females versus 30 males, P = 0.01), which probably relates to ascertainment bias. However, these modifiers had no impact on a semi-quantitative pathological phenotype in 10 autopsied patients. These data allow an appreciation of the range of clinical phenotype, modern imaging and molecular investigation and should inform genetic counselling of at-risk individuals, with the identification of two genetic modifiers
