Risk factors for transition to first episode psychosis among individuals with 'at-risk mental states'

Recently developed criteria have been successful at identifying individuals at imminent risk of developing a psychotic disorder, but these criteria lead to 50-60% false positives. This study investigated whether measures of family history, peri-natal complications, premorbid social functioning, premorbid personality, recent life events and current symptoms would be able to improve predictions of psychosis in a group of young, help-seeking individuals who had been identified as being at risk. Individuals (N=74) were followed up at least 1 year after initial assessment. Half the sample went on to develop a psychotic disorder. The most reliable scale-based predictor was the degree of presence of schizotypal personality characteristics. However, individual items assessing odd beliefs/magical thinking, marked impairment in role functioning, blunted or inappropriate affect, anhedonia/asociality and auditory hallucinations were also highly predictive of transition, yielding good sensitivity (84%) and specificity (86%). These predictors are consistent with a picture of poor premorbid functioning that further declines in the period up to transition.

Hunter DBT Project: Randomized Controlled Trial of Dialectical Behaviour Therapy in Women with Borderline Personality Disorder

Objective: Deliberate self-harm (DSH), general hospital admission and psychiatric hospital admission are common in women meeting criteria for borderline personality disorder (BPD). Dialectical behaviour therapy (DBT) has been reported to be effective in reducing DSH and hospitalization. Method: A randomized controlled trial of 73 female subjects meeting criteria for BPD was carried out with intention-to-treat analyses and per-protocol analyses. The intervention was DBT and the control condition was treatment as usual plus waiting list for DBT (TAU+WL), with outcomes measured after 6 months. Primary outcomes were differences in proportions and event rates of: any DSH; general hospital admission for DSH and any psychiatric admission; and mean difference in length of stay for any hospitalization. Secondary outcomes were disability and quality of life measures. Results: Both groups showed a reduction in DSH and hospitalizations, but there were no significant differences in DSH, hospital admissions or length of stay in hospital between groups. Disability (days spent in bed) and quality of life (Physical, Psychological and Environmental domains) were significantly improved for the DBT group. Conclusion: DBT produced non-significant reductions in DSH and hospitalization when compared to the TAU+WL control, due in part to the lower than expected rates of hospitalization in the control condition. Nevertheless, DBT showed significant benefits for the secondary outcomes of improved disability and quality of life scores, a clinically useful result that is also in keeping with the theoretical constructs of the benefits of DBT.

Adverse Incidents in Acute Psychiatric Inpatient Units: Rates, Correlates and Pressures:

Objective: This paper reports findings from a multicentre service evaluation project conducted in acute psychiatric inpatient units in NSW, Australia. Overall rates of aggression, absconding and early readmission are reported, as well as length-of-stay profiles and associations between these outcomes and selected sociodemographic and clinical characteristics routinely collected by health services. Method: Data from the 11 participating units were collected for a 12month period from multiple sources, including electronic medical records, routine clinical modules, incident forms, and shift based project-specific logs. For the current analyses, two admission-level datasets were used, comprising aggregated patient-level events (n=3242 admissions) and basic sociodemographic, clinical, admission and discharge information (n=5546 admissions by 3877 patients). Results: The participating units were under considerable strain: 23.3% of admissions were high acuity; 60.4% had previous hospital stays; 47.6% were involuntary; 25–30% involved adverse incidents; bed occupancy averaged 88.4%; median length of stay was 8days (mean=14.59days); and 17.4% had a subsequent early readmission. Reportable aggressive incidents (11.2% of admissions) were intermittent (averaging 0.55 incidents per month per occupied bed) and associated with younger age, personality disorder, less serious aggression, longer periods of hospitalization, and subsequent early readmission. Less serious aggressive incidents (15.0% of admissions) were maximal in the first 24h (averaging 3.73 incidents per month per occupied bed) and associated with younger age, involuntary status, bipolar and personality disorders, the absence of depression, and longer hospital stays. Absconding (15.7% of admissions) peaked in the second week following admission and was associated with drug and alcohol disorder, younger age, and longer periods of hospitalization. Conclusions: By examining relationships between a core set of risk factors and multiple short-term outcomes, we were able to identify several important patterns, which were suggestive of the need for a multi-level approach to intervention, shifting from a risk management focus during the early phase of hospitalization to a more targeted, therapeutic approach during the later phase. But the latter approach may not be achievable under current circumstances with existing resources.

Relationships between Computer Self-Efficacy, Technology, Attitudes and Anxiety: Development of the Computer Technology Use Scale (CTUS)

Two studies are reported which describe the development and evaluation of a new instrument, the Computer Technology Use Scale (CTUS), comprising three domains: computer self-efficacy, attitudes to technology, and technology related anxiety. Study 1 describes the development of the instrument and explores its factor structure. Study 2 used confirmatory factor analysis to evaluate the stability of the factors identified and to examine relationships between computer self-efficacy, attitudes, and anxiety. There were 479 (Study 1) and 352 (Study 2) University—recruited subjects who volunteered for the project. The initial five factor solution of the CTUS scale was confirmed which include the following factors: computer efficacy, technology related anxiety, complexity, positive attitudes, and negative attitudes. Computer efficacy was positively related to positive attitudes and negatively related to other factors. The relationship between the factors is discussed.

Distinguishing suicidal from non-suicidal deliberate self-harm events in women with Borderline Personality Disorder

Objective: Deliberate self-harm (DSH) is common in Borderline Personality Disorder, may be due to a variety of reasons, and is associated with different degrees of suicidal intent. Understanding the reasons for episodes of DSH in this population may be helpful in developing interventions to reduce the rate of DSH or to assist in the clinical judgement of suicidal intention after DSH has occurred. Methods: The Parasuicide History Interview, version 2 (PHI-2) was used to determine the reasons for DSH events in 70 Australian women diagnosed with Borderline Personality Disorder. Factor analysis of the responses identified four empirically derived component factors. Multivariate models were developed to identify the independent predictors of suicidal deliberate self-harm (S-DSH) versus non-suicidal deliberate self-harm (NS-DSH) events. Results: Participants and raters showed strong agreement in classifying S-DSH and NS-DSH events. Methods used that involved self-poisoning, jumping or stabbing showed increased risk for S-DSH, adjusted odds ratio 12.07 (95% CI 2.17, 67.29), compared to the referent group, external damage to skin with no rescue contact being sought. Although no grouping of reasons were independently significant, the lower the effectiveness of the DSH event to resolve the reasons for the event, the higher the risk of it having been a S-DSH event. Conclusion: In clinical situations, any Borderline Personality Disorder patient seeking help or medical attention, using any method other than superficial external injury to skin, or reporting a failure to effectively resolve the reasons for the DSH event, should be considered as likely to have had a S-DSH event (greater suicidal intention). However, specific reasons for the DSH event, or individual subject characteristics, did not meaningfully distinguish S-DSH from NS-DSH events.

Ten-year audit of clients presenting to a specialised service for young people experiencing or at increased risk for psychosis

BackgroundDespite strong research interest in psychosis risk identification and the potential for early intervention, few papers have sought to document the implementation and evaluation of specialised psychosis related services. Assessment of Ultra High Risk (UHR) has been given priority, but it is equally as important to identify appropriate comparison groups and other baseline differences. This largely descriptive service evaluation paper focuses on the `baseline characteristics’ of referred clients (i.e., previously assessed characteristics or those identified within the first two months following service presentation).MethodsData are reported from a 10-year layered service audit of all presentations to a `Psychological Assistance Service’ for young people (PAS, Newcastle, Australia). Baseline socio-demographic and clinical characteristics (N =1,997) are described (including clients’ psychosis and UHR status, previous service contacts, hospitalisation rates, and diagnostic and comorbidity profiles). Key groups are identified and comparisons made between clients who received ongoing treatment and those who were primarily assessed and referred elsewhere.ResultsClients averaged 19.2 (SD =4.5) years of age and 59% were male. One-tenth of clients (9.6%) were categorised as UHR, among whom there were relatively high rates of attenuated psychotic symptoms (69.1%), comorbid depression (62.3%), anxiety (42.9%), and attentional and related problems (67.5%). Overall, one-fifth (19.8%) experienced a recent psychotic episode, while a further 14.5% were categorised as having an existing psychosis (46.7% with a schizophrenia diagnosis), amongst whom there were relatively high rates of comorbid substance misuse (52.9%), psychosocial (70.2%) and physical health (37.7%) problems. The largest group presenting to PAS were those with non-psychotic disorders (43.7%), who provide a valuable comparison group against which to contrast the health trajectories of those with UHR and recent psychosis. Ongoing treatment by PAS was preferentially given to those experiencing or at risk for psychosis and those reporting greater current distress or dysfunction.ConclusionsWhether or not UHR clients transition to psychosis, they displayed high rates of comorbid depression and anxiety at service presentation, with half receiving ongoing treatment from PAS. Although international comparisons with similar services are difficult, the socio-demographic and comorbidity patterns observed here were viewed as largely consistent with those reported elsewhere.

The Effects of Lipopolysaccharide (LPS) on the Fever Response in Rats at Different Ambient Temperatures

There is a complex interplay between the immune system, nervous system, and sleep. When an organism is challenged with lipopolysacchride (LPS), the immune system is stimulated, producing a fever response that is independent of ambient temperature, and an increase in slow-wave sleep (SWS). The study investigated sleep patterns of immune-challenged rats during the light phase cycle to determine the effects of various ambient temperatures. It was hypothesised that fever response would occur independently of ambient temperatures. Also, the febrile response would be monophasic, and there would be an increase in slow-wave sleep (SWS) and a decrease in rapid-eye-movement (REM) sleep. Thirty Wistar rats were randomly placed in 3 different ambient temperature groups, 22 degrees C, 15 degrees C, and 30 degrees C. Within each of these conditions, the same subjects served as control and experimental groups. Four animals were placed in 4 subsections of 2 standard boxes that were placed in the ambient-temperature box. The electrodes were connected to the analog to digital computer board, where all the data was processed and stored on a hard drive. The animals were injected I.P. with saline and recorded for a period of 6 h to establish a baseline. On Day 2, the same animals were injected I.P. with LPS and recorded for 6 h to determine the febrile effects of LPS on the immune system; the same procedure was repeated in the other ambient temperatures. The results have shown that animals experienced a monophasic fever response in low and normal temperatures, but not in the high temperatures. Although there was no increase in SWS, there was a significant decrease in REM sleep in 3 groups.

New Fathers’ Perinatal Depression and Anxiety—Treatment Options: An Integrative Review:

More than 10% of fathers experience depression and anxiety during the perinatal period, but paternal perinatal depression (PPND) and anxiety have received less attention than maternal perinatal mental health problems. Few mainstream treatment options are available for men with PPND and anxiety. The aim of this literature review was to summarize the current understanding of PPND and the treatment programs specifically designed for fathers with perinatal depression. Eight electronic databases were searched using a predefined strategy, and reference lists were also hand searched. PPND and anxiety were identified to have a negative impact on family relationships, as well as the health of mothers and children. Evidence suggests a lack of support and tailored treatment options for men having trouble adjusting to the transition to fatherhood. Of the limited options available, cognitive behavioral therapy, group work, and blended delivery programs, including e-support approaches appear to be most effective in helping fathers with perinatal depression and anxiety. The review findings have important implications for the understanding of PPND and anxiety. Future research is needed to address the adoption of father-inclusive and father-specific models of care to encourage fathers’ help-seeking behavior. Inclusion of male-specific requirements into support and treatment options can improve the ability of services to engage new fathers. Psychotherapeutic intervention could assist to address the cognitive differences and dissonance for men adjusting to the role of father, including male identity and role expectations.

Development of a depression scale for veterans and war widows

We developed and evaluated a brief measure of depression for use within a population of older Australian war veterans and war widows. Derived from the Geriatric Depression Scale (GDS), the 12-item GDS-Veterans is designed to include items that most closely represent the thoughts and feelings of older veterans in relation to their war experiences. The scale was administered to 1,620 veterans and widows concurrent with the 36-item Medical Outcomes Study Short Form (MOS SF-36) quality of life measure. Of those surveyed, 13.5% indicated that they often or always worry about things that happened during the war, indicating that this item tapped an important dimension for many of the veteran population. Scores on the GDS-Veterans were strongly correlated with the Mental Health subscale (-.72) and the Mental Health Component Summary Score (-.68) of the MOS SF-36 quality of life measure.

An Integrated Recovery-oriented Model (IRM) for mental health services: evolution and challenges

BackgroundOver past decades, improvements in longer-term clinical and personal outcomes for individuals experiencing serious mental illness (SMI) have been moderate, although recovery has clearly been shown to be possible. Recovery experiences are inherently personal, and recovery can be complex and non-linear; however, there are a broad range of potential recovery contexts and contributors, both non-professional and professional. Ongoing refinement of recovery-oriented models for mental health (MH) services needs to be fostered.DiscussionThis descriptive paper outlines a service-wide Integrated Recovery-oriented Model (IRM) for MH services, designed to enhance personally valued health, wellbeing and social inclusion outcomes by increasing access to evidenced-based psychosocial interventions (EBIs) within a service context that supports recovery as both a process and an outcome. Evolution of the IRM is characterised as a series of five broad challenges, which draw together: relevant recovery perspectives; overall service delivery frameworks; psychiatric and psychosocial rehabilitation approaches and literature; our own clinical and service delivery experience; and implementation, evaluation and review strategies. The model revolves around the persons changing recovery needs, focusing on underlying processes and the service frameworks to support and reinforce hope as a primary catalyst for symptomatic and functional recovery. Within the IRM, clinical rehabilitation (CR) practices, processes and partnerships facilitate access to psychosocial EBIs to promote hope, recovery, self-agency and social inclusion. Core IRM components are detailed (remediation of functioning; collaborative restoration of skills and competencies; and active community reconnection), together with associated phases, processes, evaluation strategies, and an illustrative IRM scenario. The achievement of these goals requires ongoing collaboration with community organisations.ConclusionsImproved outcomes are achievable for people with a SMI. It is anticipated that the IRM will afford MH services an opportunity to validate hope, as a critical element for people with SMI in assuming responsibility and developing skills in self-agency and advocacy. Strengthening recovery-oriented practices and policies within MH services needs to occur in tandem with wide-ranging service evaluation strategies.
