ItemNo Preview AvailableAn analysis of real-time suicidal ideation and its relationship with retrospective reports among young people with borderline personality disorder(WILEY, 2024-02-20)INTRODUCTION: This study aimed to analyze the real-time variability of suicidal ideation intensity and the relationship between real-time and retrospective reports of suicidal ideation made on the Beck Scale for Suicidal Ideation (BSS), among young people with borderline personality disorder (BPD). METHODS: Young people (15-25-year olds) with BPD (N = 46), recruited from two government-funded mental health services, rated the intensity of their suicidal ideation six times per day for 7 days before completing the BSS. RESULTS: For 70% of participants, suicidal ideation changed in intensity approximately five times across the week, both within and between days. BSS ratings were most highly correlated with the highest real-time ratings of suicidal ideation. However, this was not significantly different from the relationship between the BSS and both the average and most recent ratings. Median ratings of suicidal ideation intensity were higher on the BSS compared with an equivalent question asked in real time. CONCLUSION: Findings suggest that young people with BPD experience high levels of fluctuation in their intensity of suicidal ideation across a week and that retrospective reports of suicidal ideation might be more reflective of the most intense experience of suicidal ideation across the week.

Digital interventions provide a promising solution. OBJECTIVE: Our objective was to evaluate across multiple Australian early psychosis services the effectiveness of a novel, web-based early psychosis intervention for carers. METHODS: In this cluster randomized controlled trial conducted across multiple Australian early psychosis services, our digital moderated online social therapy for carers (Altitudes) plus enhanced family treatment as usual (TAU) was compared with TAU alone on the primary outcome of perceived stress and secondary outcomes including mental health symptoms and family variables at the 6-month follow-up. RESULTS: Eighty-six caregivers were randomized and data were available for 74 young people in their care. Our primary hypothesis that carers randomized to Altitudes+TAU would report greater improvements in perceived stress at follow-up compared with carers randomized to TAU alone was not supported, with the TAU alone group showing more improvement. For secondary outcomes, the TAU alone group showed improved mindfulness over time. Regardless of group assignment, we observed improvements in satisfaction with life, quality of life, emotional overinvolvement, and burden of care. In contrast, hair cortisol concentration increased. Post hoc analyses revealed more contact with early psychosis services in the intervention group compared to TAU alone and that improvements in perceived stress and social support were associated with use of the intervention in the Altitudes+TAU group. In this study, 80% (12/15) reported a positive experience with Altitudes and 93% (14/15) would recommend it to others. CONCLUSIONS: Our trial did not show a treatment effect for Altitudes in perceived stress. However, our post hoc analysis indicated that the amount of use of Altitudes related to improvements in stress and social support. Additional design work is indicated to continue users' engagement and to significantly improve outcomes in problem-solving, communication, and self-care.

ItemNo Preview AvailableA comparison of experiences of care and expressed emotion among caregivers of young people with first-episode psychosis or borderline personality disorder features(SAGE PUBLICATIONS LTD, 2022-09-01)OBJECTIVE: Caregivers of individuals with severe mental illness often experience significant negative experiences of care, which can be associated with higher levels of expressed emotion. Expressed emotion is potentially a modifiable target early in the course of illness, which might improve outcomes for caregivers and patients. However, expressed emotion and caregiver experiences in the early stages of disorders might be moderated by the type of severe mental illness. The aim was to determine whether experiences of the caregiver role and expressed emotion differ in caregivers of young people with first-episode psychosis versus young people with 'first-presentation' borderline personality disorder features. METHOD: Secondary analysis of baseline (pre-treatment) data from three clinical trials focused on improving caregiver outcomes for young people with first-episode psychosis and young people with borderline personality disorder features was conducted (ACTRN12616000968471, ACTRN12616000304437, ACTRN12618000616279). Caregivers completed self-report measures of experiences of the caregiver role and expressed emotion. Multivariate generalised linear models and moderation analyses were used to determine group differences. RESULTS: Data were available for 265 caregivers. Higher levels of negative experiences and expressed emotion, and stronger correlations between negative experiences and expressed emotion domains, were found in caregivers of young people with borderline personality disorder than first-episode psychosis. Caregiver group (borderline personality disorder, first-episode psychosis) moderated the relationship between expressed emotion and caregiver experiences in the domains of need to provide backup and positive personal experiences. CONCLUSION: Caregivers of young people with borderline personality disorder experience higher levels of negative experiences related to their role and expressed emotion compared with caregivers of young people with first-episode psychosis. The mechanisms underpinning associations between caregiver experiences and expressed emotion differ between these two caregiver groups, indicating that different supports are needed. For borderline personality disorder caregivers, emotional over-involvement is associated with both negative and positive experiences, so a more detailed understanding of the nature of emotional over-involvement for each relationship is required to guide action.

ItemNo Preview AvailableRisk Factors for Suicide Attempt During Outpatient Care in Adolescents With Severe and Complex Depression(HOGREFE PUBLISHING CORP, 2023-05)Background: Young people receiving tertiary mental health care are at elevated risk for suicidal behavior, and understanding which individuals are at increased risk during care is important for treatment and suicide prevention. Aim: We aimed to retrospectively identify risk factors for attempted suicide during outpatient care and predict which young people did or did not attempt during care. Method: Penalized logistic regression analysis was performed in a small high-risk sample of 84 young people receiving care at Orygen's Youth Mood Clinic (age: 14-25 years, 51% female) to predict suicide attempt during care (N = 16). Results: Prediction of suicide attempt during care was only moderately accurate (Area Under the Receiver Operating Curve range 0.71; sensitivity 0.57) using a combination of sociodemographic, psychosocial, and clinical variables. The features that best discriminated both groups included suicidal ideation during care, history of suicide attempt prior to care, changes in appetite reported on the PHQ-9, history of parental separation, and parental mental illness. Limitation: Replication of findings in an independent validation sample is needed. Conclusion: While prediction of suicide attempt during care was only moderately successful, we were able to identify individual risk factors for suicidal behavior during care in a high-risk sample.

ItemNo Preview AvailableThe specific phenotype of depression in recent onset schizophrenia spectrum disorders: A symptom profile and network comparison to recent onset major depressive disorder without psychotic features(ELSEVIER, 2022-02)The specific phenotype of depression in recent-onset schizophrenia spectrum disorders (SSD) and its relation to non-psychotic depression is unknown. Symptom profile and network analysis are complementary statistical techniques that may provide important insights into the presentation and relative importance of individual symptoms that give rise to depression. The aim of the current study was to characterise the profile and network of depressive symptoms in SSD and compare it to individuals with major depressive disorder (MDD) without psychotic features. This study involved analysis of baseline data pertaining to 109 individuals with comorbid SSD and depression and 283 with MDD without psychotic features. Study cohorts were the Psychosis Recent Onset GRoningen Survey (PROGR-S) and Youth Depression Alleviation (YoDA) trials, respectively. Profile and network analyses revealed that SSD and MDD differed in the profile and relative importance of individual depressive symptoms. While reported sadness was the primary hallmark of depression in both SSD and MDD, individuals with depression in SSD were more likely to sleep more, and have lower lassitude and pessimism. While sadness had great importance in MDD and SSD, in SSD but not MDD lassitude, sleep, appetite, concentration difficulties, and inability to feel were important in the network of depressive symptoms. The specific phenotype of depression might be different in SSD compared to MDD. Symptom inequivalence or underlying functional mechanisms in SSD might result in depression in SSD that is similar to MDD with atypical features.

However, there is a lack of effective and accessible interventions for FEP carers. OBJECTIVE: To determine the effectiveness of an online intervention ("Altitudes") in relation to the primary outcome of FEP-carer stress at 6 months follow-up. METHODS: We conducted a cluster randomized controlled trial in which FEP carers were randomized to Altitudes combined with specialized treatment as usual (STAU) or STAU alone. In addition to questionnaires, we included multiple waves of intensive ecological momentary assessment (EMA) to measure carer stress and family outcomes in 164 carers of young (15-27 years) FEP patients. RESULTS: Both groups improved over time on stress and a range of secondary outcomes, including mental health symptoms, self-efficacy, and expressed emotion with no group by time interactions. At 12 months there were significantly fewer visits to emergency departments by FEP patients in the Altitudes group (p = 0.022). Modelling of multiple EMA waves revealed that more time spent by carers with FEP patients predicted greater worry, expressed emotion, and adaptive coping. CONCLUSIONS: Engagement and usability findings for Altitudes were positive. Further refinements to our online carer interventions may be needed to engage carers in purposeful skill development for improved management of stress and communication with the young person compared with existing specialist family interventions.

ItemA randomised controlled trial of a psychoeducational group intervention for family and friends of young people with borderline personality disorder features(SAGE PUBLICATIONS LTD, 2023-11)OBJECTIVE: Preliminary evidence indicates that interventions designed to support family and friends ('carers') of young people with early-stage borderline personality disorder effectively improve carer outcomes. None of these interventions have been tested in a randomised controlled trial. METHOD: This clustered, partially nested, randomised controlled trial was conducted at Orygen, Melbourne, Australia. Carers of young people (aged 15-25 years) with borderline personality disorder features were randomly assigned as a unit in a 1:1 ratio, balanced for young person's sex and age, to receive a 15-day intervention comprising: (1) the three-session, in-person, Making Sense of BPD (MS-BPD) multi-family group programme, plus two self-directed online psychoeducational modules (MS-BPD + Online, n = 38), or (2) the two self-directed online psychoeducational modules alone (Online, n = 41). The primary outcome was 'negative experiences of care', measured with the Experience of Caregiving Inventory, at the 7-week endpoint. RESULTS: A total of 79 carers were randomised (pool of 281, 197 excluded, 94 declined) and 73 carers (51 females [69.9%], Mage = 43.8 years [standard deviation, SD = 12.9], MS-BPD + Online n = 35 [47.9%], Online n = 38 [52.1%]) provided follow-up data and were included in the intent-to-treat analysis. The intent-to-treat (and per protocol) analyses did not find any significant differences between the groups on the primary (d = -0.32; 95% confidence interval = [-17.05, 3.97]) or secondary outcomes. Regardless of treatment group, caregivers improved significantly in their personality disorder knowledge. CONCLUSION: Delivering MS-BPD in conjunction with an online psychoeducational intervention was not found to provide additional benefit over and above access to an online intervention alone. In accordance with national guidelines, carer interventions should be routinely offered by youth mental health services as part of early intervention programmes for borderline personality disorder. Further research is warranted into which interventions work for whom, carers' preferences for support and barriers to care.

ItemHeterogeneity of quality of life in the later stages of first-episode psychosis recovery(SPRINGER, 2023-03)PURPOSE: First-episode psychosis (FEP) is characterised by wide heterogeneity in terms of symptom presentation and illness course. However, the heterogeneity of quality of life (QoL) in FEP is not well understood. We investigated whether subgroups can be identified using participants' responses on four QoL domains (physical health, psychological, social relationships, and environmental) 18-months into the recovery phase of FEP. We then examined the discriminant validity of these subgroups with respect to clinical, cognitive, and functioning features of FEP. METHOD: Demographic and clinical characteristics, QoL, cognition, and functioning were assessed in 100 people with FEP at the 18-month follow-up of a randomised controlled trial of Individual Placement Support, which aims to facilitate vocational recovery. QoL was measured using the World Health Organisation's QoL-BRIEF. A two-stage clustering approach using Ward's method and Squared Euclidean Distance with a k-means confirmation was conducted. Multinomial logistic regressions were used to establish external validity. RESULTS: Three QoL subgroups emerged: a 'good' subgroup with relatively high QoL across all domains (31%), an 'intermediate' subgroup with relatively low psychological QoL (48%) and a 'poor' subgroup with markedly low social relationship QoL (21%). Negative symptoms, depressive symptoms, social/occupational functioning, and social inclusion at follow-up predicted subgroup membership. Sensitivity analysis found similar results. CONCLUSION: Although some individuals with FEP have QoL comparable to individuals without mental ill health, QoL can remain concerningly low despite treatment efforts. Future research on interventions that target factors associated with poor QoL, such as low social inclusion, is required to counteract prolonged poor QoL in FEP.

ItemNo Preview AvailableMindfulness-Based Online Intervention to Improve Quality of Life in Late-Stage Bipolar Disorder: A Randomized Clinical Trial(AMER PSYCHOLOGICAL ASSOC, 2021-10)Objective: Adjunctive psychological interventions improve outcomes in bipolar disorder (BD), but people in latter stages likely have different clinical needs. The objective here was to test the hypothesis that for people with ≥10 episodes of BD, a brief online mindfulness-based intervention (ORBIT 2.0) improves quality of life (QoL) relative to a Psychoeducation control. Method: A rater-masked, pragmatic superiority randomized clinical trial compared ORBIT 2.0 with active control. Both interventions were 5-week coach-supported programs with treatment as usual continued. Inclusion criteria included age 18-65 years, confirmed diagnosis of BD, and history of ≥10 episodes. Measures were collected at baseline, postintervention, and 3- and 6-month follow-ups. The main outcome was QoL, measured on the Brief Quality of Life in Bipolar Disorder (Brief QoL.BD) at 5 weeks, using intention-to-treat analyses. Results: Among N = 302 randomized participants, the primary hypothesis was not supported (Treatment × Time β = -0.69, 95% CI [-2.69, 1.31], p = .50). The main effect of Time was not significant in either condition, indicating no improvement in either group. Recruitment was feasible, the platform was safe, both interventions were highly acceptable, but usage was suboptimal. Post hoc analyses found both interventions effective for participants not in remission from depression at baseline. Conclusions: In people with late-stage BD, an online mindfulness-based intervention was not superior to psychoeducational control in improving QoL. Online delivery was found to be safe and acceptable. Future interventions may need to be higher intensity, address engagement challenges, and target more symptomatic individuals.

ItemNo Preview AvailableInterrelationships between depressive symptoms and positive and negative symptoms of recent onset schizophrenia spectrum disorders: A network analytical approach(PERGAMON-ELSEVIER SCIENCE LTD, 2021-08)OBJECTIVE: There is a need to better understand the interrelationships between positive and negative symptoms of recent-onset schizophrenia spectrum disorders (SSD) and co-occurring depressive symptoms. Aims were to determine: (1) whether depressive symptoms are best conceptualised as distinct from, or intrinsic to, positive and negative symptoms; and (2) bridging symptoms. METHODS: Network analysis was applied to data from 198 individuals with depressive and psychotic symptoms in SSD from the Psychosis Recent Onset GRoningen Survey (PROGR-S). Measures were: Montgomery-Åsberg Depression Rating Scale and Positive and Negative Syndrome Scale. RESULTS: Positive symptoms were just as likely to be associated with depressive and negative symptoms, and had more strong associations with depressive than negative symptoms. Negative symptoms were more likely to be associated with depressive than positive symptoms, and had more strong associations with depressive than positive symptoms. Suspiciousness and stereotyped thinking bridged between positive and depressive symptoms, and apparent sadness and lassitude between negative and depressive symptoms. CONCLUSIONS: Depressive symptoms might be best conceptualised as intrinsic to positive and negative symptoms pertaining to deficits in motivation and interest in the psychotic phase of SSD. Treatments targeting bridges between depressive and positive symptoms, and depressive and such negative symptoms, might prevent or improve co-occurring depressive symptoms, or vice-versa, in the psychotic phase of SSD.
