Suicide risk assessment fears, attitudes and behaviours of lifeline crisis supporters.

Lifeline Australia operates crisis support services through Lifeline Crisis Supporters. An integral part of their role is to conduct online suicide risk assessments with help-seekers. However, there is limited literature regarding suicide risk assessment practices for this population. This study aimed to examine how suicide prevention training, vicarious trauma and fears impacted suicide risk assessment behaviours of Lifeline Crisis Supporters. A cross-sectional survey design was used to recruit a volunteer convenience sample of 125 Lifeline Australia Crisis Supporters (75.2% females; Mage  = 54.9) in 2018 to participate in an online survey. Findings revealed that those with more suicide-specific training had less risk assessment-related fears, and that fears were not related to attitudes towards suicide prevention. There was no significant relationship between vicarious trauma and amount of training or years of experience in the role. Further, participants with higher levels of vicarious trauma demonstrated significantly more negative attitudes towards suicide prevention. Overall, training appears to be a significant factor in suicide risk assessment practice behaviours of Lifeline Crisis Supporters, highlighting a need for ongoing training and support for them. This research also suggests that whilst fears exist, they do not significantly impair Lifeline Crisis Supporters' ability to undertake suicide risk assessment.

The effects of implementation intentions on prospective memory in young and older adults.

Prospective memory (PM) is the ability to perform a planned action at a future time, while carrying on with other unrelated tasks. Implementation Intentions (II) is a promising metacognitive strategy for improving PM in older adults, though its generalization and longer-term effects are not well-understood. We examined the effects of II on PM in 48 community-dwelling older adults (77% female, M age = 71.52) and 59 young adults (75% female, M age = 19.86). Participants were randomly allocated to a conventional instruction or II group and administered a laboratory-based PM task in the first session. In the second session, participants returned to complete a similar but new laboratory-based PM task and an ecological PM task without prompts to use a strategy. We found strong age effects on PM performance whereby older adults performed worse than young adults across all PM tasks. While the overall facilitation effect of II was not statistically significant, there was a trend that this strategy facilitated PM performance on the laboratory-based PM task in the first session for older adults with a medium sized effect (d = 0.37). The generalization and longer-term effect of II were not significant for either the similar laboratory-based or the ecological PM task. These results suggest that a single-session II intervention may not be sufficient to elicit transfer to other similar new PM tasks in healthy populations.

Understanding the Neural Basis of Prospective Memory Using Functional Near-Infrared Spectroscopy.

Prospective memory (PM) is the ability to perform a planned action at an intended future time. This study examined the neural correlates of PM using functional near-infrared spectroscopy (fNIRS). This study employed a within-participants design. A laboratory PM task was adapted for use with fNIRS to investigate regions of interest and levels of brain activation during task performance in 32 participants (63% female, Mage = 21.31 years, SDage = 4.62 years). Participants first completed a working memory (WM) task (N-back ongoing task) followed by a WM plus PM task while neural activity was measured using fNIRS. Behavioral results revealed an interference effect for reaction time on the WM task, whereby participants were significantly slower to respond in the WM plus PM task compared to the WM task. Ongoing task accuracies did not differ between the two conditions. fNIRS results revealed a higher level of neural activity in the fronto-polar prefrontal cortex and dorsolateral prefrontal cortex in the WM plus PM task compared to the WM Condition. These findings highlight that fNIRS is a suitable tool for studying and understanding the neural basis of PM.

Suicide and suicide attempts in the Pacific Islands: A Systematic Literature Review.

BACKGROUND: The Pacific Islands have some of the highest rates of suicide in the Western Pacific region. The purpose of this study was to systematically review the literature on suicidal behaviour in the Pacific Islands. METHODS: A comprehensive search of Web of Science, PubMed, PsycINFO, Cochrane, CINAHL and Embase databases was conducted for all articles published until 1st February 2021. Inclusion criteria included papers that referred to a pre-specified list of Pacific Islands. Papers referring exclusively to other countries were excluded. Other exclusion criteria included not being about suicide or suicide attempts or not presenting original research. Narrative synthesis was applied without meta-analysis. The review followed PRISMA guidelines. FINDINGS: A total of 36 papers were included for review. Of the Pacific Islands, Kiribati has the highest age-standardised rate of suicide mortality. Key risk groups across the Islands included youth, people of Indian ethnicity in Fiji (a prominent ethnic group in Fiji), and Indigenous peoples across other Islands. Prominent methods were self-poisoning and hanging. A distinct lack of intervention studies was found. INTERPRETATION: Overall, the Pacific Islands appear to have relatively high rates of suicide and suicide attempts compared to other countries in the region. This was particularly striking among youth. This review provides important directions for future suicide prevention activities, including means restriction, sensitive media/community coverage, enhanced surveillance, and the development and evaluation of interventions tailored to the needs of young people and other cultural groups. FUNDING: None.

Revisiting the Age-Prospective Memory Paradox Using Laboratory and Ecological Tasks.

Prospective memory (PM) is the ability to perform a planned action at a future time. Older adults have shown moderate declines in PM, which are thought to be driven by age-related changes in the prefrontal cortex. However, an age-PM paradox is often reported, whereby deficits are evident in laboratory-based PM tasks, but not naturalistic PM tasks. The key aims of this study were to: (1) examine the age-PM paradox using the same sample across laboratory and ecological settings; and (2) determine whether self-reported PM and cognitive factors such as working memory and IQ are associated PM performance. Two PM tasks were administered (ecological vs. laboratory) to a sample of 23 community-dwelling older adults (Mage = 72.30, SDage = 5.62) and 28 young adults (Mage = 20.18, SDage = 3.30). Participants also completed measures of general cognitive function, working memory, IQ, and self-reported memory. Our results did not support the existence of the age-PM paradox. Strong age effects across both laboratory and ecological PM tasks were observed in which older adults consistently performed worse on the PM tasks than young adults. In addition, PM performance was significantly associated with self-reported PM measures in young adults. For older adults, IQ was associated with time-based PM. These findings suggest that the age-PM paradox is more complex than first thought and there are differential predictors of PM performance for younger and older adults.

A suicide prevention initiative at a jumping site: A mixed-methods evaluation.

BACKGROUND: Gap Park in Sydney, Australia has historically been recognised as a suicide jumping site. In 2010-2011 the Gap Park Masterplan initiative implemented a series of suicide prevention measures. This study applied a mixed-methods design to evaluate the effectiveness of the Masterplan in reducing suicides. METHODS: Data from the Australian National Coronial Information System (NCIS) was examined to compare suicides at Gap Park before and after the Masterplan was implemented. This was complemented with qualitative data from interviews with police officers who respond to suicidal behaviours at Gap Park. FINDINGS: Joinpoint analysis of NCIS data showed a non-significant upward trend in jumping suicides during the study period. A significant upward trend in suicides was seen for females before the implementation of the Masterplan (2000-2010), followed by a significant downward trend from the implementation period onwards (2010-2016) for females: however, a non-significant upward trend for males was observed. Qualitative analysis of police interviews identified six key themes: romanticism and attraction at hotspots, profiles and behavioural patterns of suicidal individuals, responding to a person in a suicidal crisis, repeat attempts, means restriction, and personal impacts on police officers. INTERPRETATION: The mixed-method study provided important insights, suggesting the Gap Park Masterplan has contributed to a reduction in female, but not in male jumping suicides. Further qualitative information from police officers suggested that the safety barriers were not difficult to climb, and may be more of a visual or psychological barrier. However, the effectiveness of CCTV and alarms in the detection and location of suicide attempters was highlighted. FUNDING: Lifeline Research Foundation.

A drink before suicide: analysis of the Queensland Suicide Register in Australia.

AIMS: Previous studies analysing blood alcohol concentration (BAC) at the time of suicide have primarily focused on sociodemographic factors. Limited research has focused on psychosocial factors and co-ingestion of other substances to understand the mechanisms of how alcohol contributes to death by suicide. The aim was to examine time trends, psychosocial factors related to acute alcohol use and co-ingestion of alcohol and other substances before suicide. METHODS: The Queensland Suicide Register in 2004-2015 was utilised and analysed in 2019. The cut-off point for positive BAC was set at ⩾0.05 g/dl. Substances were categorised as medicines, illegal drugs and other. Medicines were coded by the Anatomical Therapeutic Chemical (ATC) classification system. Joinpoint regression, univariate odds ratios, age and sex-adjusted odds ratios and Forward Stepwise logistic regression were performed. RESULTS: BAC information was available for 6744 suicides, 92% of all cases in 2004-2015. The final model showed that independent factors distinguishing BAC+ from BAC- were: age group 25-44 years, Australian Indigenous background, being separated or divorced, hanging, diagnosis of substance use, lifetime suicidal ideation, relationship and interpersonal conflict, not having psychotic and other psychiatric disorder, and no nervous system drugs or any other substances in blood at the time of suicide. CONCLUSIONS: Our findings suggest that people who die by suicide while under the influence of alcohol are more likely to be under acute stress (e.g. separation) and not have earlier psychiatric conditions, except substance use. This highlights the importance of more strict alcohol policies, but also the need to improve substance use treatment.

Wesley LifeForce Suicide Prevention Gatekeeper Training in Australia: 6 Month Follow-Up Evaluation of Full and Half Day Community Programs.

Background and Objective: Wesley Mission LifeForce training is an Australian suicide prevention gatekeeper program which has not been formally evaluated. The aims of this evaluation were to (1) determine the short- and medium- term impacts of the training on worker capabilities (perceived and declarative knowledge), attitudes, and reluctance to intervene measures; and (2) compare the impact of the half and full day workshops on these measures. Method: 1,079 Australian community workers of diverse professional backgrounds completed a pre-workshop questionnaire as part of registration for the Wesley LifeForce suicide prevention training between 2017 and 2019. Of these, 299 participants also completed the post workshop questionnaires (matched sample). They attended either half day (n = 97) or full day workshops (n = 202) and completed also a 3- and 6- month follow-up questionnaire. We used linear mixed-effect modeling for repeated measures to analyze data. Results: LifeForce training participants experienced an increase in perceived capability, declarative knowledge, more positive attitudes and reduced reluctance to intervene, at least in the short term. The program is particularly well targeted for community gatekeepers with no prior training, albeit those with prior training in this study also experienced positive and significant gains on most measured constructs. Conclusions: We found evidence of effectiveness of the Wesley LifeForce training over time, without difference between the short (half day) and longer (full day) formats of delivery. Nevertheless, the latter format offers skills-based and skills rehearsal opportunities, the impacts of which we were unable to measure in this evaluation and should be estimated in the future.

Profiles by suicide methods: an analysis of older adults.

OBJECTIVE: The aim of this study was to investigate choice of suicide method in individuals aged 65 years and over. METHODS: Data were obtained from the Queensland Suicide Register, Australia. Univariate and multi-variate logistic regression analyses were conducted. RESULTS: The predominant methods in older adults were hanging (21.5%), firearms and explosives (20.9%), drug poisoning (18.5%), followed by other poisoning (mainly MVCO) (12.6%), suffocation by plastic bag (8.5%), and drowning (6%). Some methods (e.g. firearms and explosives, drug poisoning, suffocation) appeared characterised by profiles (e.g., socio-demographic and clinical aspects), meanwhile others were not well distinguishable. Compared to other methods, those who died by firearms and explosives were significantly more likely to be males, Australian born, live in rural and remote areas, and less likely to have a mental illness, previous suicide attempt(s) or leave a suicide note. Those who died by drug poisoning were more likely to be females, leave a suicide note, experience interpersonal conflict and live in urban areas. Similarly, those who chose suffocation by plastic bag were more likely to be older females, leave a suicide note, and pay attention to suicide in the media, but less likely to experience interpersonal conflict. CONCLUSION: Acceptability, availability and lethality are important factors impacting choice of means and should be considered when designing suicide prevention activities in older adults.

Suicide in older adults: differences between the young-old, middle-old, and oldest old.

BACKGROUND: In the limited research into suicides in older adults, they have been treated as a homogenous group without distinguishing between different age groups. This study aimed to compare differences in sociodemographic variables, recent life events, and mental and physical illnesses between three age groups within older adults who died by suicide: young-old (65-74 years), middle-old (75-84 years), and oldest old (85 years and over) in Queensland, Australia, during the years 2000-2012 (N = 978). METHODS: The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated. Odds ratios with 95% confidence intervals and χ 2 tests for trend were calculated to examine differences between the three groups. RESULTS: Suicide rates were increasing with age for males, but not for females. Hanging and firearms were the predominant methods of suicides. However, suffocation by plastic bag and drowning as suicide methods increased with age, in contrast firearms and explosives decreased with age. Overall, psychiatric problems, suicidal behavior, legal and financial stressors, and relationship problems decreased significantly with age, meanwhile physical conditions and bereavement increased with age. CONCLUSION: Suicide across older adulthood is not a homogenous phenomenon. Our findings showed significant differences in the prevalence of potential risk factors within the three different age groups considered. To prevent suicide in older adults would require targeting specific factors for each subgroup while using holistic and comprehensive approaches.
