Background Adults with Borderline Personality Disorder (BPD) manifest poor performance on tasks of decision making which may be congruent with their decisional and interpersonal conflicts in real life. Poor decision making is often assumed to be due to impulsive behaviour or weak inhibitory control despite inconsistent evidences of these relationships, leaving questions about the specific nature of these decisional deficits. Decision making in BPD may be compromised by different domains of impulsivity, affective dysregulatory processes or unknown co-morbid ADHD which is considered a developmental precursor to BPD. Findings Iowa Gambling Task (IGT) decision making, 2 tasks of inhibitory control and a self report of ADHD symptoms consisting of 9 subscales were administered to 41 BPD women and 41 healthy controls. No group differences in inhibitory control were present. Net decision making performance and all ADHD subscale ratings differed significantly among BPD women and healthy controls. BPD women did not meet the threshold indicative of moderate to severe ADHD. Three subscales of attention, behaviour/ disorganized and emotive were significantly associated with poor IGT performance in 26 women with BPD. Of these 3 variables, the emotive subscale, representing a rapid emotional response, was the only significant predictor contributing 49% to the variance in poor DM. Conclusions This is the 1st evidence of an emotive type of impulsivity, representing a type of affective instability that is linked to poor IGT DM in BPD. Findings support the Somatic Marker Hypothesis of IGT DM and may reflect the affective dysregulation that characterizes the disorder.

Background Nurses working in acute care psychiatry settings experience high rates of patient violence which influences outcomes for nurses and the organization. This qualitative study explored psychiatric nurses’ experiences of patient violence in acute care inpatient psychiatric settings. Methods An interpretive descriptive design guided this study that included 17 semi-structured interviews with a purposeful sample of 12 Canadian registered nurses who self-reported experiencing patient violence within acute care inpatient psychiatry. Thematic analysis and constant comparison techniques were used for analysis. A problem, needs and practice analysis was also used to structure overall data interpretation. Results Thirty three unique exposures to patient violence among the sample of nurses were analysed. Nurses reported experiencing physical, emotional and verbal violence. For many, patient violence was considered “part of the job.” Nurses often struggled with role conflict between one’s duty to care and one’s duty to self when providing care following a critical incident involving violence. Issues of power, control and stigma also influenced nurse participant perceptions and their responses to patient violence. Nurses used a variety of strategies to maintain their personal safety and to prevent, and manage patient violence. Nurses endorsed the need for improved education, debriefing following an incident, and a supportive work environment to further prevent patient violence. Present findings have implications for reducing the barriers to reporting violent experiences and the creation of best practice guidelines to reduce patient violence in the workplace. Conclusions Understanding the perspectives and experiences of nurses in acute inpatient psychiatry leads to greater understanding of the phenomenon of patient violence and may inform the development of interventions to prevent and to respond to patient violence, as well as support nurses working within the acute care setting.

Objective: In subjects with borderline personality disorder (BPD), compared with subjects who attempted suicide, to review neuropsychological (NP) function that may predispose to suicidal behaviour along a continuum of high and low lethality. Method: We undertook electronic searches of MEDLINE, PsycINFO, EMBASE, Biosos Reviews, and Cinhal. The searches were restricted to English-language publications from 1985 onward. The search terms borderline personality disorder, suicide, suicide attempt, self-harm behaviour, neuropsychological, executive function (EF), neurocognitive, and neuropsychological function produced 29 neuropsychology studies involving BPD and 7 neuropsychology studies of suicide attempters, regardless of psychiatric diagnosis. Results: Of the BPD studies, 83% found NP impairment in one or more cognitive domains, irrespective of depression, involving specific or generalized deficits linked to the dorsolateral prefrontal and orbitofrontal regions. The functions most frequently reported (in 71% to 86% of BPD studies) are response-inhibitory processes affecting executive function performance that requires speeded attention and visuomotor skills. Decision making and visual memory impairment are also most frequently affected; 60% to 67% of BPD studies report attentional impairment, verbal memory impairment, and visuospatial organizational impairment. Least affected processes in BPD appear to involve spatial working memory, planning, and possibly, IQ. The similarities in NP deficits found in BPD and suicide-attempt studies involve decision making and Trails performances. BPD studies, however, reflect more frequent impairment on the Stroop Test and Wisconsin Card Sort Test performance than the suicide-attempt studies, whereas verbal fluency appears to be more frequently impaired in those attempting suicide. Conclusions: Impaired EF and disinhibitory processes, as indicated by verbal fluency, Trails, and Stroop performance, primarily associated with dorsolateral prefrontal cortical regions may represent a dominant executive pathway to suicide attempt. A primary motivational inhibitory pathway involving conflictual, affective, and reflexive decision-making processes associated with orbitofrontal brain regions, in combination with significant cognitive rigidity, may influence the repetitive expression of self-harm or low-lethality suicidal behaviour. The hypothesis of a specific trait-like cognitive vulnerability for suicidal behaviour involving dysregulatory, disinhibiting pathways awaits confirmation.

The affective decision making of 41 recently treated outpatient women with borderline personality disorder (BPD) was compared to 41 healthy controls using the Iowa Gambling Task (IGT). Non-affective executive functions (EF) of working memory, interference control, and motor inhibition were also compared. Associations among affective and non-affective EF were examined. Despite normal range intelligence, Stroop interference, motor inhibition, and working memory, women with BPD made significantly more disadvantageous IGT decisions than controls (Cohen's d = .72) that were unrelated to substance abuse history, education, psychotropic use, or attentional deficits. Correlates of EF and IGT performance varied by group. Intellect, BPD, and intact behavioral control explained 35% of the adjusted variance in net IGT performance. Disadvantageous IGT decision making was the only EF to predict BPD. IGT deficits in BPD may be separable from IQ and other EF as supported by the somatic marker hypothesis and suggest a stable, trait-like vulnerability favoring immediate reward over long-term gain in women with the disorder.

PARTICIPANTS 25 parents (18 mothers, 7 fathers) of 18 young people (13-16 y of age) with mental health problems. METHODS Parents were interviewed about the following topics: the nature of their child's problem; relationships with health professionals; implications for their lifestyle, health, employment, and education; impact on the family; and coping. CONCLUSIONS Parents of young people with mental health problems found that their caregiving role changed through interactions with health professionals.

The patient did not respond to typical treatment for BPD. Because BPD has historically been considered a single disorder, treatments have tended to be unitary in dimension.

Neuropsychological deficits may perpetuate the risk and chronicity of psychiatric disorder. Borderline Personality Disorder, characterized by significant suicide risk, intense affect and behavioural dysregulation, is frequently associated with the executive function (EF) deficits of decision making and inhibitory control. However, the role of inhibitory control on decision making remains poorly understood. This study examined the relationships among working memory, cognitive and motor inhibitory control, and IGT decision-making performance in 41 women with BPD and 41 healthy controls. Associations among EF and suicide risk were also explored. Experimental tasks included the Iowa Gambling Task, Digit Span, Stroop and Stop Tasks, and Raven's Matrices. Only IGT decision-making deficits distinguished BPD subjects from healthy controls. Weaker yet normal range IQ and EFs in BPD women did not explain their disadvantageous IGT performance. Contrary to expectations, IGT deficits in BPD women did not predict any suicidal risk; however, intact interference control was as sensitive to suicidal risk as was depression. Normal interference control was associated with a reduction in suicide risk. While IGT decision making may be a marker for BPD, Stroop interference control is more sensitive to suicide risk and may represent a vulnerability for suicide that exists beyond psychiatric diagnosis.
