Mental health matters: A cross-sectional study of mental health nurses' health-related quality of life and work-related stressors

Mental health nursing is widely recognized as a stressful occupation; however, little is known about the relationship between work-related stress and health-related quality of life of mental health nurses (MHN). This study aimed to identify MHN health-related quality of life (HR-QoL) and work-related stressors; associations between stressors and HR-QoL; and predictors of HR-QoL. An online cross-sectional survey collected demographic data, work-related stressors and HR-QoL (SF-12v2) of n = 498 Australian MHN. Prominent consumer/carer-related stressors were verbal (90%) and physical aggression (85%). Collegial stressors included staff conflict (71%) and bullying (55%), and colleague-perpetrated verbal (34%) and physical aggression (7%). Key organizational stressors included high workloads (74%), lack of organizational support (60%) and lack of adequate resources to perform nursing role (58%). The mean physical health score was 52.62 (SD = 8.30), and mental health score was 43.59 (SD = 11.34), with mental health substantially lower than national norms (mean difference = 10.11). There were statistically significant negative correlations between the number of work-related stressors and HR-QoL. Younger (21-30 years) and less experienced (<1-4 years) MHN had substantially lower mental health. Higher mental health was predicted with < 15 stressors, >4 years' experience and working in the community. The poorer mental health of MHN has concerning implications for the well-being, retention and practice of the largest group in the mental health workforce. There is a critical need for organizations to enact effective policy and initiatives to reduce workplace aggression, improve staff psychological and physical safety, and strengthen well-being and resilience. New graduates are a priority group for urgent intervention.

'Anyone can have a mental illness': A qualitative inquiry of pre-registration nursing students' experiences of traditional mental health clinical placements

Nurses play a crucial role in mental healthcare provision. Like many countries, Australian nursing students are educated in comprehensive pre-registration programmes which include mental health clinical placements. Placements play a vital role in students' education, providing the opportunity to engage with consumers and develop mental health nursing knowledge and skills. There is limited knowledge of student perspectives on traditional placements in contemporary recovery-oriented mental health services. This interpretive qualitative inquiry aimed to explore nursing students' experience of traditional mental health clinical placement and how it influenced their practice and their understandings of recovery from mental illness. Data were collected from focus groups with n = 31 nursing students in a large metropolitan public mental health service. Thematic analysis resulted in three themes of experience: humanizing people with mental illness; learning about recovery; and shifting perspectives on mental health nursing. Through a positive placement experience where they felt supported and included by staff, students came to see consumers as people rather than diagnoses, developed greater understanding of mental health nursing work and were more likely to consider mental health nursing as a career choice. Peer-support workers were an important influence on students' understandings of recovery and have a key role to play in educating students on placement. Students need to be prepared and supported by university and clinical staff to deal with vicarious trauma that may occur on placement. Mental health placements play a crucial role in attracting students into the field, and it is imperative they remain part of comprehensive pre-registration education.

Improving physical health outcomes for people with severe mental illness: A proof-of-concept study of nurse practitioner candidate practice

People with severe mental illness have significantly reduced life expectancy and higher risk of cardiovascular diseases than the general population. There is a critical need for quality physical health care to improve consumers' health outcomes. There is minimal knowledge, however, on the impact of mental health nurse practitioner candidate (NPC) practices on consumers' health outcomes. The aim of this proof-of-concept study was to describe the impacts of NPC practices on the quality of physical healthcare provision and physical health outcomes (cardiovascular and cardiometabolic) of consumers in community mental health service settings. Using a mixed methods design, quantitative data were collected for 12 months prior to (Period 1), and 12 months during (Period 2), the candidacy period. Qualitative interviews were conducted with a purposive sample of n = 10 consumers to explore their perspectives on physical healthcare provision by the NPCs. During the 12-month candidacy period, the number of metabolic monitoring assessments rose from n = 55 in Period 1 to n = 146 in Period 2 (P < 0.01, χ²  = 41.20). Advanced practices provided by NPCs included taking an extensive holistic history and clinical examination, ordering diagnostic pathology, and clinical simulation of physical health medication prescription (under medical supervision). Analysis of consumer interviews resulted in two themes: (i) positive and helpful NPC health care and (ii) improvements in physical and mental health. The findings add new knowledge on specialist mental health nurse practitioner candidate roles and demonstrate the benefits these roles can have in reducing the significant morbidity and mortality of mental health consumers.

Workplace stressors, psychological well-being, resilience, and caring behaviours of mental health nurses: A descriptive correlational study

There is widespread recognition that workplace stress can have profound negative impacts on nurses' well-being and practice. Resilience is a process of positive adaptation to stress and adversity. This study aimed to describe mental health nurses' most challenging workplace stressors, and their psychological well-being, workplace resilience, and level of caring behaviours, explore the relationships between these factors, and describe differences in workplace resilience for sociodemographic characteristics. In a descriptive correlational study using convenience sampling, data were collected from N = 498 nurses working in mental health roles or settings in Victoria Australia via an online cross-sectional survey. Key findings included weak to strong (r = 0.301 to r = 0.750) positive relationships between workplace resilience with psychological well-being across all stressor categories (consumer/carer; colleague; organizational role; and organizational service). Psychological well-being was moderately high, but lower for nurses indicating consumer/carer-related stressors as their most stressful challenge. There were weak to moderate (r = 0.306 to r = 0.549) positive relationships between workplace resilience and psychological well-being, and no relationship between resilience and caring behaviours. Workplace resilience was lower (P < 0.05) for less experienced nurses compared with those with >5 years' experience, and lower for younger nurses compared with those aged ≥40 years. To improve their resilience and prevent psychological distress, there is prime opportunity to support nursing students with well-being and resilience-building strategies during their undergraduate education, and to support new graduates with similar programmes when they enter the workforce.

Undergraduate nursing students' stigma and recovery attitudes during mental health clinical placement: A pre/post-test survey study

Undergraduate nursing students have been reported to hold negative and stigmatizing attitudes towards mental health consumers and to be under-prepared for mental health clinical placement. This study aimed to investigate undergraduate nurses' stigma and recovery attitudes to mental illness, and describe their understandings of personal recovery on entry and exit to traditional mental health clinical placement. A pre/post-test survey was administered to N = 249 nursing students in Australia. Demographic data, attitudes towards mental health nursing and clinical placement, the Opening Minds Scale for Healthcare Providers (OMS-HC), Recovery Attitudes Questionnaire (RAQ-7), and an open-ended question on understandings of personal recovery from mental illness were collected on entry (T1) and exit (T2) to placement. At T1, students reported moderate stigma and positive attitudes towards recovery (OMS-HC mean = 34.6; RAQ-7 mean = 4.0). At T2, there was a reduction in stigma (social distance P = 0.02, d = 0.26) and improvement in recovery attitudes (P < 0.01, d = 0.40). Attitudes towards mental health nursing and placement also improved (P < 0.01). Having a family member with mental illness predicted improvements in stigma and recovery attitudes. On entry to placement, most students described accurate understandings of personal recovery, which were maintained during placement. The findings indicate that mental health clinical placements are effective in improving students' mental health stigma and recovery attitudes and provide a prime opportunity to attract students into the field. Co-produced or consumer-led education provided by peer workers during clinical placements may improve students' stigmatizing attitudes and stimulate their interest to work in the field.

Quality of life and personal resilience in the first two years after breast cancer diagnosis: systematic integrative review

The aim of this systematic integrative review was to examine the early impacts of a breast cancer diagnosis (up to 2 years after diagnosis) in relation to quality of life and personal resilience. The bibliographic databases of Medline, CINAHL, Cochrane, and Psychology and Behavioral Science Collection were searched using predetermined search criteria. Research studies published up to February 2019 were considered and following appraisal 36 articles were included in the review. Younger age, disease progression at first presentation, personality factors such as optimism, and moderators such as social support, clinical interventions and development of self-management abilities predicted better quality of life and personal resilience. Not recovering from the physical and psychological impacts of a new diagnosis has implications for future mental and physical health. This systematic, integrative review highlighted that building resilience and working with women's strengths should be the focus for contemporary clinical interventions for women in the early period after diagnosis of breast cancer.

Brief interventions to de-escalate disturbances in emergency departments

This study aimed to systematically review evidence to assess the efficacy of non-pharmacological brief interventions in the emergency department to reduce the incidence, severity and impact of acute behavioural disturbances. The literature search was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 18 articles were identified as meeting the inclusion criteria and read in full. Following a full read and a consensus discussion, it was subsequently considered the studies chosen had not met the inclusion criteria. Research into the use of non-pharmacological brief interventions in the management of acute behavioural disturbance in the emergency department is warranted given the absence of evidence found by this systematic review.

Analysis of the experiences of nurses who return to nursing after cancer

BACKGROUND

understanding the impact of role ambiguity (both professional and patient) can be a factor in deepening the understanding of the ongoing personal, professional and organisational requirements of nurses who are cancer survivors.

PURPOSE

the aim of this qualitative study was to elucidate an in-depth description of nurses' experiences of surviving cancer.

METHOD

an exploratory qualitative research design was used (n=8), with participants recruited between September 2014 and December 2016.

DISCUSSION

data analysis led to the emergence of six themes: being practical about the diagnosis and treatment, empathy and compassion, a 'new normal' and the role of organisational support, medical knowledge and treatment experiences, coping in silence and denial, and being resilient.

CONCLUSION

nurses as cancer survivors who return to work offer a richness of experience related to enhanced empathetic responses to patients in their care and have the potential to be great practice role-models for other staff.

Recovery in early stage breast cancer-An Australian longitudinal study

BACKGROUND

The majority of breast cancer patients will experience some level of emotional distress, with some patients having long-term psychological maladjustment. Personal and social resources play a role in recovery yet the interplay between these factors warrants further examination. This study aimed to investigate the interaction of psychosocial factors impacting women in their breast cancer trajectory, at 2 years or less following diagnosis (stages I-III).

DESIGN

A longitudinal cohort study approach was used in this study.

METHODS

The sample consisted of n = 49 participants. Data were collected between June 2013 and October 2013 and followed for 12 months across the trajectory of the disease.

RESULTS

The mean age was 56.6 years (SD 11.6 years). Most participants had stage I or stage II breast cancer. Time (over three time points-4 weeks, 6 months, and 12 months) after diagnosis was significantly associated with the body image (P = .003) and age (P = .004).

CONCLUSION

Older women with breast cancer reported less concern regarding body image than their younger peers. These findings suggest that posttreatment younger women may require access to psychological support posttreatment.

The impact of brief lifestyle self-management education for the control of seizures

AIM:

this study examined a brief lifestyle self-management intervention, based on self-determination theory, to manage seizure frequency, and its effects on health-related quality of life and resilience in people with epilepsy aged over 18 years.

BACKGROUND:

most people with epilepsy can identify factors that may trigger seizures and may try to avoid these; however, education from clinicians on this varies.

DESIGN:

a cohort study with control design.

METHOD:

sixty participants were purposively sampled and allocated to an intervention or a control group.

RESULTS:

moderate correlations were found, particularly between: resilience and satisfaction with life; medication adherence and psychological quality of life; and psychological quality of life and satisfaction with life. The mean seizure occurrences between the control and intervention groups were 12.71 (SD 24.55) and 6.76 (SD 13.40) respectively after the intervention. While the study was not powered to assess this, the intervention may be most effective regarding medication adherence and physical health quality of life.

CONCLUSION:

the relationship between self-efficacy and seizure management appeared to be strengthened by the programme. This study is the first known to measure resilience in relation to lifestyle self-management for seizure control in people with epilepsy. Relevance to practice: nurses are well placed to work with patients' strengths towards self-efficacy and potentially resilient coping.

Resilience and mental health nursing: An integrative review of international literature

Mental health nurses work in challenging and potentially high stress settings. Stressors can occur in the context of consumer, family, and/or staff relationships, as well as the work environment and organization. The cumulative effects of stress and professional challenges can lead to harmful impacts for mental health nurses including burnout and poorer physical and mental health. Resilience involves a process of positive adaptation to stress and adversity. The aims of this integrative review were to examine understandings and perspectives on resilience, and explore and synthesize the state of knowledge on resilience in mental health nursing. Following systematic search processes, screening, and data extraction, 12 articles were included. Constant comparative analysis and synthesis of the data resulted in two key categories: Theoretical concepts of resilience and Knowledge on mental health nurses' resilience. In mental health nursing, resilience has been variously constructed as an individual ability, collective capacity, or as an interactive person-environment process. Resilience was most often reported as low-moderate, with positive correlations with hardiness, self-esteem, life and job satisfaction, and negative correlations with depression and burnout. A resilience programme improved mental health nurses' coping self-efficacy and capacity to regulate thoughts and emotions and developed their resilient practice. Use of contemporary resilience definitions will inform more consistent investigation and progressively scaffold knowledge of this emergent construct in mental health nursing. Future research on the implementation of resilience programmes and resilience-building strategies for mental health nurses at the individual, work unit, and organizational levels is needed.

Nursing Practices in Catholic Healthcare: A Case Study of Nurses in a Catholic Private Hospital

We aimed to investigate Catholic Identity and Mission communication specifically how nurses were expressing the Catholic healthcare values in practice. A mixed-methods, case study design was used and included non-participant observation, a mid-level manager focus group (n = 7) and online surveys (n = 144). Document and observational data analysis revealed the organisation's commitment to visible indication of Catholic values adherence. Focus group analysis revealed two themes, 'Catholic values in action' and 'taking the extra step'. The impact of Catholic Identity and Mission on nurses and nursing care recipients remains elusive and warrants further understanding.

General hospital health professionals' attitudes and perceived dangerousness towards patients with comorbid mental and physical health conditions: Systematic review and meta-analysis

The stigmatization of mental health is present in general hospital settings impacting quality of care. We hypothesized that health professionals in these areas would elicit negative attitudes and a perceived level of dangerousness across a range of mental health disorders. We aimed to conduct a systematic review and meta-analysis to examine these attitudes and perceptions. We searched the bibliographic databases of CINAHL Complete, MEDLINE Complete, PsycINFO, and Psychology and Behavioral Sciences Collection in May 2017 (no date parameters were set). Quantitative studies investigating generalist health professionals' attitudes towards mental health conditions were selected. Initially, prevalence meta-analyses were conducted to assess the extent of perceived danger, followed by a series of comparative meta-analyses in which the perceived dangerousness of mental health conditions was compared. Of the 653 citations retrieved, eight studies met the inclusion criteria. The overall sample included 2548 health professionals. A majority of health professionals perceived patients with substance use disorder as dangerous 0.60 (95% CI: 0.32-0.88) when compared with patients who had an alcohol-related disorder, schizophrenia, and depression. The results also indicated that a large proportion of staff perceived patients with a diagnosis of schizophrenia as dangerous 0.42 (95% CI: 0.33-0.52). Negative attitudes towards people experiencing mental illness in general hospital settings may be attributed to poor mental health literacy, skills and limited exposure, and social and cultural beliefs about mental illness. Ongoing professional development targeting mental health knowledge is recommended for health professionals working in general hospital settings.

Emotional labour in mental health nursing: An integrative systematic review

Emotional labour is the effort consumed by suppressing one's own emotions to care for others effectively while also caring for oneself. Mental health nurses are required to engage in effective therapeutic interactions in emotionally-intense situations. The aim of the present integrative systematic review was to investigate the emotional labour of mental health work and how this manifested, the impacts, and the ways to mitigate these impacts. In June 2016, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology, a systematic search of the bibliographic databases was undertaken to identify relevant literature. Screening, data extraction, and synthesis were performed by three reviewers. The inclusion criteria included any original research that investigated the emotional work of mental health nurses. We identified a total of 20 papers to be included in this review. Thematic synthesis of the findings revealed three emergent themes: emotional labour and caring, emotional exhaustion, and self-protection (expressed as emotional intelligence). Emotional labour, emotional exhaustion, and emotional intelligence were considered to be intrinsically linked, where they were both the influencing factor for burnout and a contributor to attrition. The results highlighted that emotional labour could inspire the development and personal growth of emotional intelligence in mental health nurses. In light of these findings, recommendations for clinical practice were considered; they included supportive work environments, involving nurses in shared decision-making, and the provision of ongoing professional development opportunities that facilitate the development of emotional intelligence and resilience.

Point-of-care testing of activated clotting time in the ICU: is it relevant?

BACKGROUND

Over the past 50 years there have been significant advances in both the clinical techniques and equipment used in the intensive care environment. One traditionally used point-of-care test is activated clotting time (ACT), a coagulation test primarily used during cardiopulmonary bypass surgery to monitor the anticoagulation effects of heparin. The ACT test has since emerged into the intensive care environment to guide clinical assessment and management of haemostasis in postoperative cardiac patients.

OBJECTIVES

The aim of this integrative systematic review was to critique the available research evaluating the effectiveness of ACT point-of-care testing in the intensive care unit for adult patients following cardiopulmonary bypass and cardiac surgery and any impacts this may have on nursing care.

METHODS

A systematic search of Medline, CINAHL and PubMed was undertaken.

RESULTS

The search identified five research papers reporting on the use of ACT point-of-care testing in the intensive care unit for adult cardiac surgical patients. Meta-analysis was not performed due to the lack of homogeneity between the papers included.

CONCLUSIONS

There was a lack of clear evidence for the use of the ACT point-of-care test after cardiac surgery in the intensive care environment. This review has highlighted that conventional laboratory tests are generally more accurate and reliable than this point-of-care test in guiding nursing care management.

Personal Descriptions of Life Before and After Bariatric Surgery From Overweight or Obese Men

Bariatric surgery is now a common weight loss solution for morbidly obese men where meaningful weight reduction and improvements in quality of life have been identified postsurgery. As the majority of surgical candidates are female, there exists a paucity of literature relating to the experience of males undergoing bariatric surgery. In this study, a qualitative descriptive-exploratory design was used to explore body image descriptions, adaptation of a new lifestyle, new boundaries postsurgery, and any barriers seeking consultation for surgery. Six males who had undergone bariatric surgery were recruited in Australia. Data were collected and analyzed using NVivo between May and October 2014. The themes emerging from the data included living in an obese body, life before surgery, decision making for surgery, and life after surgery. The participants collectively reported that life before surgery was challenging. They described the changes the surgery had made in their lives including positive changes to their health, body image, social lives, and self-esteem. Some participants preferred not to tell others their intentions for surgery due to perceived stigma. The men in this study also described a lack of information available to them depicting male perspectives, a possible barrier for men seeking weight loss surgery options. Implications for practice highlighted in these results relate to a greater need for accessible information specific to men based on real-life experiences.

An Australian longitudinal pilot study examining health determinants of cardiac outcomes 12 months post percutaneous coronary intervention

Background

Percutaneous coronary intervention (PCI) is a very common revascularisation procedure for coronary artery disease (CAD). The purpose of this study was to evaluate cardiac outcomes, health related quality of life (HRQoL), resilience and adherence behaviours in patients who have undergone a PCI at two time points (6 and 12 months) following their procedure.

Methods

A longitudinal pilot study was conducted to observe the cardiac outcomes across a cohort of patients who had undergone a percutaneous coronary intervention (PCI). Participants who had undergone PCI 6 months prior were invited. Those participants who met the inclusion criteria and provided consent then completed a telephone survey (time point 1). These participants were then contacted 6 months later (i.e. 12 months post-intervention, time point 2) and the measures were repeated.

Results

All patients (n = 51) were recorded as being alive at time point 1. The multiple model indicated that controlling for other factors, gender was significantly associated with a linear combination of outcome measures (p = 0.004). The effect was moderate in magnitude (partial-η² = 0.303), where males performed significantly better than females 6 months after the PCI procedure physically and with mood. Follow-up univariate ANOVAs indicated that gender differences were grounded in the scale measuring depression (PHQ9) (p = 0.005) and the physical component score of the short form measuring HRQoL (SF12-PCS) (p = 0.003). Thirteen patients were lost to follow-up between time points 1 and 2. One patient was confirmed to have passed away. The pattern of correlations between outcome measures at time point 2 revealed statistically significant negative correlation between the PHQ instrument and the resilience scale (CD-RISC) (r = -0.611; p < 0.001); and the physical component score of the SF-12 instrument (r = -0.437; p = 0.054).

Conclusions

Men were performing better than women in the 6 months post-PCI, particularly in the areas of mood (depression) and physical health. This pilot results indicate gender-sensitive practices are recommended particularly up to 6 months post-PCI. Any gender differences observed at 6 month appear to disappear at 12 months post-PCI. Further research into the management of mood particularly for women post-PCI is warranted. A more detailed inquiry related to access/attendance to secondary prevention is also warranted.

USING THE TEAM TO REDUCE RISK OF BLOOD AND BODY FLUID EXPOSURE IN THE PERIOPERATIVE SETTING

INTRODUCTION

Despite the substantial risks posed in the surgical environment, compliance in wearing appropriate personal protective equipment (PPE) in the operating room (OR) and the post-anaesthetic care unit (PACU) amongst health care workers is considered poor globally. Lack of awareness and limited access to information about the appropriate precautions to prevent exposure contribute to continued high-risk behaviours amongst the team in the perioperative setting.

AIM

The aim of this project was to assess current compliance rates of staff in the use of PPE and to develop and implement an educational program to increase staff compliance in the perioperative setting of a large, private hospital (450 beds).

METHOD

A convenience sample of perioperative nurses were invited to complete a questionnaire.

RESULTS

Eighty (80) registered nurses RNs) were invited to participate response rate of 69%), giving a sample size of n = 55. Questionnaires not completed in full were not included in the final analysis, leaving n = 31 fully completed questionnaires. There was an education group (n = 14) and a control group (n = 17). Between the groups, educational background, type of work and patient contact were very similar. Of those that did respond regarding exposure, only 20% reported the incident. Both groups identified their manager and team as frequently discussing safer work practices and being supportive. PPE was identified as essential; however, participants reported not enough time to always follow standard precautions (education 15%; control 25%).

CONCLUSIONS

Team and good leadership was identified as essential to ongoing professional knowledge and support with regard to risk minimisation in the perioperative setting.

A systematic review and meta-analysis of factors that relate to aggression perpetrated against nurses by patients/relatives or staff

AIMS AND OBJECTIVES

The aim of this meta-analysis was to identify the factors that related to aggression (verbal abuse or physical abuse/assault) perpetrated against the nurse or other health professionals by patients/relatives or staff. In the light of the paucity of systematic reviews on this common issue in nursing, the objective was to present a comprehensive systematic review and meta-analysis of these papers.

BACKGROUND

Aggression towards nurses is common around the world and can be the impetus for nurses leaving the profession or developing anxiety when working in particular settings.

DESIGN

Systematic review with meta-analysis.

METHODS

Meta-analyses were conducted to assess the effect of the factors of gender and context (dichotomised as mental health/psychiatric or nonmental health/psychiatric). The databases of Medline (1966-2015), CINAHL (1982-2015) and PsychInfo (1920-2015).

RESULTS

A total of 1571 papers were screened by two reviewers. At the final decision 14 were selected for analysis. A higher proportion of female nurses than male nurses were reported to be the victims of verbal abuse, with the difference in proportions being statistically significant. A statistically significant higher proportion of male nurses than female nurses were reported to be the victims of physical abuse. There was a significantly higher proportion of mental health nurses reported experiencing physical abuse as compared to nonmental health nurses.

CONCLUSIONS

The analysis reveal female nurses have greater odds of verbal abuse than male nurses and male nurses have greater odds of physical abuse than female nurses. Overall mental health nurses had three times higher odds of physical assault than other nurses.

RELEVANCE TO CLINICAL PRACTICE

In the light of the findings it is recommended organisational support improve in high aggression potential clinical areas and for nursing curriculums to incorporate education about the management of challenging behaviours in undergraduate programmes.

The phenomenon of co-morbid physical and mental illness in acute medical care: the lived experience of Australian health professionals

Background

An estimated 30–50% of patients admitted to acute medical care settings experience co-morbid physical and mental illness. Research suggests that health professionals in these settings find managing this patient group challenging. A number of studies have investigated health professional’s attitudes and perceptions however there is limited research that investigates the lived experience in a current Australian healthcare context. The aim of this study was to explicate an in-depth description of the health professional’s experience when caring for patients experiencing co-morbid physical and mental illness in Australian acute medical care settings.

Methods

A phenomenological design was undertaken with six participants representing nursing and medical disciplines. In 2013–2014 one-on-one semi-structured interviews were used and the data collected underwent thematic analysis using an extended version of Colaizzi’s phenomenological inquiry.

Results

Six themes emerged including—challenging behaviours, environmental and organisational factors, lack of skills, knowledge and experience, hyper-vigilance and anxiety, duty of care and negative attitudes with an overarching theme of fear of the unknown.

Conclusions

Staff in acute medical care settings were unsure of patients with mental illness and described them as unpredictable, identifying that they lacked requisite mental health literacy. Regular training is advocated.
