Before I Die: death positivity and the community nursing contribution.

This article explores the contextual backdrop of the death-positive movement that inspired the discussion group Before I Die: Worcestershire, along with the motivations behind its creation. It explores the balance between practical, planning discussions and open-ended talks held by the group, emphasising the importance of creativity when responding to the topics of death and dying. The collaborative efforts between Before I Die: Worcestershire and other groups and persons involved in the death-positive movement are also highlighted. This article considers the potential of grassroots community movements to engage people to make plans for their dying, regardless of circumstances and background. It argues that death-positive movements, projects and initiatives can be a valuable way for community nurses to engage with the population they serve.

Being an end-of-life doula.

This article describes what an end-of-life doula is, the training involved and how these individuals can help someone achieve the death they want, reflecting on a role that has existed traditionally in communities for centuries without formal recognition. How end-of-life doulas work holistically but also practically will be considered, outlining how keeping the dying person's preferences and wishes at the heart of their care is the primary aim. Recent issues such as advance care planning, digital legacy and Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) will be reflected on through the lens of the end-of-life doula, with the aim of encouraging open discussion and death oracy as a life skill and creating a space to make choices about the end of life. Also explored is how an end-of-life doula works within an integrative model of healthcare, working in partnership with health professionals.

A Cross-National Examination of Differences in Classification of Lifetime Alcohol Use Disorder Between DSM-IV and DSM-5: Findings from the World Mental Health Survey.

BACKGROUND: The current study sought to examine the diagnostic overlap in DSM-IV and DSM-5 alcohol use disorder (AUD) and determine the clinical correlates of changing diagnostic status across the 2 classification systems. METHODS: DSM-IV and DSM-5 definitions of AUD were compared using cross-national community survey data in 9 low-, middle-, and high-income countries. Participants were 31,367 respondents to surveys in the World Health Organization's World Mental Health Survey Initiative. The Composite International Diagnostic Interview, version 3.0, was used to derive DSM-IV and DSM-5 lifetime diagnoses of AUD. Clinical characteristics, also assessed in the surveys, included lifetime DSM-IV anxiety; mood and drug use disorders; lifetime suicidal ideation, plan, and attempt; general functional impairment; and psychological distress. RESULTS: Compared with DSM-IV AUD (12.3%, SE = 0.3%), the DSM-5 definition yielded slightly lower prevalence estimates (10.8%, SE = 0.2%). Almost one-third (n = 802) of all DSM-IV abuse cases switched to subthreshold according to DSM-5 and one-quarter (n = 467) of all DSM-IV diagnostic orphans switched to mild AUD according to DSM-5. New cases of DSM-5 AUD were largely similar to those who maintained their AUD across both classifications. Similarly, new DSM-5 noncases were similar to those who were subthreshold across both classifications. The exception to this was with regard to the prevalence of any lifetime drug use disorder. CONCLUSIONS: In this large cross-national community sample, the prevalence of DSM-5 lifetime AUD was only slightly lower than the prevalence of DSM-IV lifetime AUD. Nonetheless, there was considerable diagnostic switching, with a large number of people inconsistently identified across the 2 DSM classifications.

Effect of cationic molecules on the oxygen reduction reaction on fuel cell grade Pt/C (20 wt%) catalyst in potassium hydroxide (aq, 1 mol dm(-3)).

This study investigates the effect of 1 mmol dm(-3) concentrations of a selection of small cationic molecules on the performance of a fuel cell grade oxygen reduction reaction (ORR) catalyst (Johnson Matthey HiSPEC 3000, 20 mass% Pt/C) in aqueous KOH (1 mol dm(-3)). The cationic molecules studied include quaternary ammonium (including those based on bicyclic systems) and imidazolium types as well as a phosphonium example: these serve as fully solubilised models for the commonly encountered head-groups in alkaline anion-exchange membranes (AAEM) and anion-exchange ionomers (AEI) that are being developed for application in alkaline polymer electrolyte fuel cells (APEFCs), batteries and electrolysers. Both cyclic and hydrodynamic linear sweep rotating disk electrode voltammetry techniques were used. The resulting voltammograms and subsequently derived data (e.g. apparent electrochemical active surface areas, Tafel plots, and number of [reduction] electrons transferred per O2) were compared. The results show that the imidazolium examples produced the highest level of interference towards the ORR on the Pt/C catalyst under the experimental conditions used.

Comorbidity of common mental disorders with cancer and their treatment gap: findings from the World Mental Health Surveys.

OBJECTIVE: This study aimed to study the comorbidity of common mental disorders (CMDs) and cancer, and the mental health treatment gap among community residents with active cancer, cancer survivors and cancer-free respondents in 13 high-income and 11 low-middle-income countries. METHODS: Data were derived from the World Mental Health Surveys (N = 66,387; n = 357 active cancer, n = 1373 cancer survivors, n = 64,657 cancer-free respondents). The World Health Organization/Composite International Diagnostic Interview was used in all surveys to estimate CMDs prevalence rates. Respondents were also asked about mental health service utilization in the preceding 12 months. Cancer status was ascertained by self-report of physician's diagnosis. RESULTS: Twelve-month prevalence rates of CMDs were higher among active cancer (18.4%, SE = 2.1) than cancer-free respondents (13.3%, SE = 0.2) adjusted for sociodemographic confounders and other lifetime chronic conditions (adjusted odds ratio (AOR) = 1.44, 95% CI 1.05-1.97). CMD rates among cancer survivors (14.6%, SE = 0.9) compared with cancer-free respondents did not differ significantly (AOR = 0.95, 95% CI 0.82-1.11). Similar patterns characterized high-income and low-middle-income countries. Of respondents with active cancer who had CMD in the preceding 12 months, 59% sought services for mental health problems (SE = 5.3). The pattern of service utilization among people with CMDs by cancer status (highest among persons with active cancer, lower among survivors and lowest among cancer-free respondents) was similar in high-income (64.0%, SE = 6.0; 41.2%, SE = 3.0; 35.6%, SE = 0.6) and low-middle-income countries (46.4%, SE = 11.0; 22.5%, SE = 9.1; 17.4%, SE = 0.7). CONCLUSIONS: Community respondents with active cancer have higher CMD rates and high treatment gap. Comprehensive cancer care should consider both factors.

Energy conservation for fatigue management in multiple sclerosis: a pilot randomized controlled trial.

OBJECTIVE: To develop and test the feasibility of an energy conservation programme to manage fatigue in multiple sclerosis. DESIGN: A pilot randomized controlled trial. SETTING: Community setting. SUBJECTS: People with multiple sclerosis reporting fatigue. INTERVENTIONS: An energy conservation programme was compared to a peer support group. Both interventions were delivered in group format with 2-hour sessions once a week for five weeks. Patients' views about the interventions were sought in discussion groups one week post intervention. MAIN MEASURES: The primary feasibility outcomes were recruitment and adherence. Other outcome measures were the Fatigue Impact Scale, Fatigue Severity Scale, MS-Impact Scale-29, MS Self-efficacy Scale, Beck's Depression Scale-Fast Screen and Epworth Sleepiness Scale. Outcomes were administered at baseline, post intervention, 6-week and 3-month follow-up. RESULTS: Almost 30% of the people approached to take part in the study did not commit to participation because of transport/time issues. Twenty-three patients took part in the study. Three patients dropped out, one reporting adverse effects. A power calculation indicated that a sample of 56 (28 per group) would be required for a main randomized controlled trial. Patients valued peer support and those in the energy conservation group described the programme as useful, but reported difficulties completing some practice activities. CONCLUSION: An energy conservation programme in the community is feasible and welcomed by people with multiple sclerosis. However, future research needs to consider longer follow-ups and practical issues to improve recruitment rate by accommodating to patients' needs.

New understandings of fathers' experiences of grief and loss following stillbirth and neonatal death: A scoping review.

OBJECTIVE: To report on research conducted on men's experiences of grief and loss following stillbirth and neonatal death in high-income, Western countries. DESIGN: This review was guided by the following research questions: 1. The impact of perinatal death for men 2. The meaning of the loss for a father's sense of identity 3. The extent to which men were able to express grief while supporting their partners and, 4. how men's experience of grief was mediated by the support and care received by health professionals. DATA SOURCES: We searched the following databases: Medline; PsychINFO; CINAHL to identify relevant articles published from the year 2000 onwards. The searches were run between 1/04/2018 and 8/4/2018. REVIEW METHODS: A scoping review was conducted of nursing, psychological, medical and social science databases using these key words: fathers' grief, men's grief, perinatal loss and death, stillbirth and neonatal death. RESULTS: Studies indicated that men reported less intense and enduring levels of psychological outcomes than women but were more likely to engage in avoidance and coping behaviours such as increased alcohol consumption. Men felt that their role was primarily as a 'supportive partner' and that they were overlooked by health professionals. CONCLUSIONS: Further research is needed on men's experience of grief following perinatal death, especially on their physical and mental well-being. IMPACT: This review addressed the problem of the lack of knowledge around paternal needs following perinatal death and highlighted areas which researchers could usefully investigate with the eventual aim of improving care for fathers.

Readiness to change and barriers to treatment seeking in college students with a mental disorder.

BACKGROUND: College students have high prevalence of mental disorders and suicidal thoughts and behaviours, and low rates of treatment uptake. This study assesses treatment access, intentions to seek help, and perceived barriers to help-seeking, considering gender and suicidal thoughts or behaviours (STBs) as predictors. METHODS: Data is from the Ulster University Student Wellbeing study (2015) conducted in Northern Ireland (NI), as part of the WHO World Mental Health Surveys International College Student Project. Participants are 392 new college entrants (162 males (41.3%)/230 females (58.7%)), who all reported some lifetime mental disorder or STBs. RESULTS: Receipt of treatment was low (37.8%), particularly among males and those with no STBs. Males were less likely to intend to access external professional services and were less likely than females to rate embarrassment (OR = 0.60) or worry about being treated differently (OR = 0.63) as important reasons for not seeking treatment. Those with STBs rated wanting to handle things on their own as a more important barrier those with no STBs (OR = 0.55 for non STBs group) and rated being unsure where to go as a less important barrier than those with no STBs (OR = 1.80 for non STBs group). LIMITATIONS: Data is correlational and concerns lifetime criteria for mental disorder, with no consideration of current mental status nor disorder type. CONCLUSIONS: These findings have implications for the active screening and intervention for vulnerable college students, particularly males and those with mental disorders but no STBs.

Use of Prescription Medication by Individuals Who Died by Suicide in Northern Ireland.

To understand medication use prior to suicide in relation to patterns, polypharmacy, and adherence. A total of 1,371 suicide cases were coded and latent class analysis used to identify combinations of medications prescribed prior to death. Two thirds had been prescribed medication with 30.7% prescribed 3 or more. Latent class analysis revealed three classes: Mixed medication use, primarily mental medication use, and baseline/low medication use. There are potentially high rates of medication non-adherence. Not only medication use but also non-adherence rates were high in this sample of individuals who died by suicide. Potential implications and areas for future research are discussed.

The moderating impact of childhood adversity profiles and conflict on psychological health and suicidal behaviour in the Northern Ireland population.

Childhood adversities are key etiological factors in the onset and persistence of psychopathology. In Northern Ireland the Troubles also impacted on the population's psychological health. This study used data from the Northern Ireland Study of Health and Stress a collaborative epidemiological study which used the WMH-CIDI to assess mental health disorders in a nationally representative sample (Part 2, n = 1986). The aims of the study were to assess co-occurrences of childhood adversities and investigate the impact of adversity profiles and conflict experience on psychopathology and suicidal behaviour. Latent Class Analysis uncovered 3 discrete childhood adversity profiles, a low, medium, and high risk class. Individuals from higher risk adversity profiles displayed significantly increased odds of having psychological problems, with conflict exposure also impacting on psychopathology. However, the study revealed that the impact of conflict exposure on suicidal behaviour was moderated by latent class membership and that some adversity may actually be protective. The findings highlight the need to consider that, while adversity can have a negative impact on psychopathology, a lack of adversity early in life may hinder some people from developing adequate coping strategies. Further research is required to identify adversity patterns and other interacting factors that are protective.

The mediating role of various types of social networks on psychopathology following adverse childhood experiences.

BACKGROUND: Adverse childhood events can have a very negative impact on psychopathology. Those with good social support networks may benefit from these relationships, with social networks protecting a person against the negative effect of childhood adversities. However, individuals who suffer early adversity may have lower levels of social networks due to these experiences. The primary aims of the current study were: 1) to examine the mediating effects of social networks on psychopathology following adverse childhood experiences and 2) to assess if childhood adversities impact on the development of social networks. METHOD: Data was obtained from the Northern Ireland Study of Health and Stress (NISHS), conducted as part of the World Mental Health Survey Initiative, n = 1986, response rate 64.8%. The WMHCIDI was used to assess mental health disorders along with risk and protective factors. RESULTS: Individuals who experienced childhood adversities had increased odds of psychopathology, especially those who experienced high levels of maltreatment. This was partially mediated by various types of social networks, including family and friend support and family harmony. However, individuals who experienced adversity were less likely to have good social networks in the first instance. LIMITATIONS: The cross-sectional nature of the study which is based on the population in Northern Ireland may limit the findings. CONCLUSION: The study illustrates the importance of social networks following adverse childhood experiences. The findings provide support for initiatives to help children gain skills to develop and maintain social networks following childhood adversities, thereby reducing the negative mental health impact of such experiences.

Population attributable fractions of psychopathology and suicidal behaviour associated with childhood adversities in Northern Ireland.

Childhood adversities are strong predictors of psychopathology and suicidality. However, specific adversities are associated with different outcomes, with cross-national variations reported. The current study examined rates of adversities reported in Northern Ireland (NI), and associations between adverse childhood experiences and psychopathology and suicidal behaviour were explored. Data was obtained from the Northern Ireland Study of Health and Stress (NISHS), conducted as part of the World Mental Health (WMH) survey initiative (2004-2008); response rate 68.4% (n = 1,986). The on-line survey used, the WHO Composite International Diagnostic Interview (CIDI) to examine psychopathology and associated risk factors in the NI population. Prevalence rates of retrospectively reported childhood adversities were calculated, with gender and age variations explored. Females were more likely to experience sexual abuse. Individuals who grew up during the worst years of the civil conflict in NI experienced elevated levels of childhood adversities. Participants who endured childhood adversities were more likely to have mental health problems but variations in risk factors were found for different disorders. Parental mental illness was associated with all disorders however, with ORs ranging from 2.20 for mood disorders to 4.07 for anxiety disorders. Population attributable fractions (PAF) estimated the reduction in psychopathology and suicidal behaviour in the population if exposure to adverse childhood events had not occurred. The highest PAF values were revealed for parental mental illness and sexual abuse. The findings indicate that a substantial proportion of psychopathology and suicide risk in NI are attributable to childhood adversities, providing support for early intervention and prevention initiatives.

Socio-demographic, mental health and childhood adversity risk factors for self-harm and suicidal behaviour in College students in Northern Ireland.

BACKGROUND: Prevalence estimates of suicidal behaviour in the college student population are consistently higher than rates for the general adult population. This study examines mental health disorders and childhood adversities as predictors of self-harm and suicidal behaviours. METHODS: The Ulster University Student Wellbeing study commenced in September 2015 as part of the WHO World Mental Health Surveys International College Student Project. In Northern Ireland (NI) 739 students participated (462 female, 274 male and 3 other specified), with the WMH-CIDI used to examine psychopathology. Mean age was 21 years old. RESULTS: Thirty-one percent endorsed suicidal ideation (24.3% of males and 36.9% of females) with almost 1 in 5 students having made a plan for suicide in the 12 months prior to the survey. Latent profile analysis revealed three profiles of childhood adversity (high, moderate, and low risk). Logistic regression analyses showed that there was an increased likelihood of all queried self-harm and suicidal behaviours in those who were not heterosexual orientation, and among those with either moderate or high levels of childhood adversities. Probable alcohol dependence was associated with a significantly increased likelihood of suicide attempt or self-harm with either a suicide plan or a suicide attempt. LIMITATIONS: Influences of self-report measures and the generalizability of the sample are discussed. CONCLUSIONS: Policies and strategies for early identification of those with mental illnesses or adversities that increase their risk, should be prioritised. It would also be useful to identify individuals at risk in secondary schools to allow for additional support to be offered to them during the key time of transitioning into higher education.

A cross-sectional study of self-reported back and neck pain among English schoolchildren and associated physical and psychological risk factors.

This study set out to identify the associations between ergonomics and other factors with back and neck pain among schoolchildren. Self-reported questionnaires were used to record health outcomes and potential risk factors in state schools. Six hundred and seventy-nine schoolchildren from Surrey in the United Kingdom aged 11-14 years took part. Twenty-seven percent of children reported having neck pain, 18% reported having upper back pain, and 22% reported having low back pain. A forward stepwise logistic regression was performed with pain categories the dependent variables. Neck pain was significantly associated with school furniture features, emotional and conduct problems, family history of low back pain and previous treatment for musculoskeletal disorders. Upper back pain was associated with school bag weight (3.4-4.45 kg), school furniture features, emotional problems and previous treatment for musculoskeletal disorders. Low back pain was associated with school furniture features, emotional problems, family history and previous injury or accident. It is important to recognise the influence of physical, psychological and family factors in children's pain.

Mental health, behavioural problems and treatment seeking among students commencing university in Northern Ireland.

Mental health and behavioural problems are common among students commencing university. University life can be stressful and problems often exacerbate during their course of study, while others develop disorders for the first time. The WHO World Mental Health Surveys International College Student Project aims to conduct longitudinal research to examine and monitor student mental health and wellbeing. The Ulster University Student Wellbeing study, which commenced in September 2015 in Northern Ireland (NI), was conducted as part of this initiative (wave 1, n = 739), using the WMH-CIDI to examine psychopathology. Baseline prevalence rates of lifetime and 12-month mental health and substance disorders, ADHD and suicidality were high, with more than half of new undergraduate students reporting any lifetime disorder. Co-morbidity was common with 19.1% of students experiencing three or more disorders. Logistic regression models revealed that females, those over 21, non-heterosexual students, and those from a lower SES background were more likely to have a range of mental health and behavioural problems. Overall, 10% of new entry students received treatment for emotional problems in the previous year. However, 22.3% of students with problems said they would not seek help. The study provides important information for universities, policy makers and practice, on mental health and wellbeing in young people generally but particularly for students commencing university. The findings will assist in the development and implementation of protection and prevention strategies in the university setting and beyond.

Substance dependence among those without symptoms of substance abuse in the World Mental Health Survey.

The World Health Organization (WHO) World Mental Health (WMH) Survey Initiative uses the Composite International Diagnostic Interview (CIDI). The first 13 surveys only assessed substance dependence among respondents with a history of substance abuse; later surveys also assessed substance dependence without symptoms of abuse. We compared results across the two sets of surveys to assess implications of the revised logic and develop an imputation model for missing values of lifetime dependence in the earlier surveys. Lifetime dependence without symptoms of abuse was low in the second set of surveys (0.3% alcohol, 0.2% drugs). Regression-based imputation models were built in random half-samples of the new surveys and validated in the other half. There were minimal differences for imputed and actual reported cases in the validation dataset for age, gender and quantity; more mental disorders and days out of role were found in the imputed cases. Concordance between imputed and observed dependence cases in the full sample was high for alcohol [sensitivity 88.0%, specificity 99.8%, total classification accuracy (TCA) 99.5%, area under the curve (AUC) 0.94] and drug dependence (sensitivity 100.0%, specificity 99.8%, TCA 99.8%, AUC 1.00). This provides cross-national evidence of the small degree to which lifetime dependence occurs without symptoms of abuse. Imputation of substance dependence in the earlier WMH surveys improved estimates of dependence.

Suicide in Northern Ireland: An Analysis of Gender Differences in Demographic, Psychological, and Contextual Factors.

BACKGROUND: The circumstances surrounding death by suicide can give us insight into the factors affecting suicide risk in particular regions. AIMS: This study examined gender and circumstances surrounding death by suicide in Northern Ireland from 2005 to 2011. METHOD: The study analyzed 1,671 suicides (77% male and 23% female cases) using information contained from the coroner's files on suicides and undetermined deaths. RESULTS: Hanging was the most common method and more than one third of the deceased had prior suicide attempts. There was evidence of alcohol use in 41% of the cases. Only, 61% of cases had recorded adverse events; most had multiple and complex combinations of experiences. Relationship and interpersonal difficulties were the most common category of adverse event (40.3%). However, illness and bereavement, employment /financial crisis, and health problems were also common. One third of those who died by suicide were employed, compared with 50.3% who were not in employment. Just over half (50.1%) were known to have a mental health disorder. CONCLUSION: The results provide the first profile of deaths by suicide in Northern Ireland. They highlight the need to target people who have difficult life experiences in suicide prevention work, notably men, people with employment, financial and relationship crises, and those with mental disorders.

Suicidality and profiles of childhood adversities, conflict related trauma and psychopathology in the Northern Ireland population.

BACKGROUND: Over 30 years of conflict in Northern Ireland (NI) has impacted on the population's mental health. However, childhood adversities may add to the psychological impact of conflict. The aims of the study were to assess co-occurrence across childhood adversities, conflict related traumas, and psychological health, then explore demographic variations between identified classes, and examine the impact of class membership on suicidal ideation and behaviour. METHOD: Data was obtained from the Northern Ireland Study of Health and Stress, a representative epidemiological study which used the CIDI to assess psychopathology and related risk factors in the NI population (N=4340, part 2 n=1986; response rate 64%). RESULTS: Latent Class Analysis uncovered 4 discrete profiles; a conflict class (n=191; 9.6%), a multi-risk class endorsing elevated levels of childhood adversities, conflict related traumas and psychopathology (n=85; 4.3%), a psychopathology class (n=290; 14.6%), and a low risk class (n=1420; 71.5%). Multinomial logistic regression analysis revealed that individuals who grew up during the worst years of the Troubles were more likely to have experienced multiple traumas and psychopathology. Individuals in the multi-risk class were more than fifteen times more likely to endorse suicidal ideation and behaviour. LIMITATIONS: The main limitations are that the study may not be fully representative of the NI population due to the exclusion criteria applied and also the possible misclassification of conflict related events. CONCLUSIONS: The findings indicate that treatment providers should be cognisant that those with wide ranging adversity profiles are those also likely to be reporting psychological distress and suicidality.

Childhood adversity profiles and adult psychopathology in a representative Northern Ireland study.

Childhood adversities are key aetiological factors in the onset and persistence of psychopathology. The aims of this study were to identify childhood adversity profiles, and investigate the relationship between the adversity classes and psychopathology in Northern Ireland. The study utilized data from the Northern Ireland Study of Health and Stress, an epidemiological survey (N=1986), which used the CIDI to examine mental health disorders and associated risk factors. Latent Class Analysis revealed 3 distinct typologies; a low risk class (n=1709; 86%), a poly-adversity class (n=122; 6.1%), and an economic adversity class (n=155; 7.8%). Logistic Regression models revealed that individuals in the economic adversity class had a heightened risk of anxiety and substance disorders, with individuals in the poly-adversity class more likely to have a range of mental health problems and suicidality. The findings indicate the importance of considering the impact of co-occurring childhood adversities when planning treatment, prevention, and intervention programmes.

Pediatric-Onset and Adult-Onset Separation Anxiety Disorder Across Countries in the World Mental Health Survey.

OBJECTIVE: The age-at-onset criterion for separation anxiety disorder was removed in DSM-5, making it timely to examine the epidemiology of separation anxiety disorder as a disorder with onsets spanning the life course, using cross-country data. METHOD: The sample included 38,993 adults in 18 countries in the World Health Organization (WHO) World Mental Health Surveys. The WHO Composite International Diagnostic Interview was used to assess a range of DSM-IV disorders that included an expanded definition of separation anxiety disorder allowing onsets in adulthood. Analyses focused on prevalence, age at onset, comorbidity, predictors of onset and persistence, and separation anxiety-related role impairment. RESULTS: Lifetime separation anxiety disorder prevalence averaged 4.8% across countries (interquartile range [25th-75th percentiles]=1.4%-6.4%), with 43.1% of lifetime onsets occurring after age 18. Significant time-lagged associations were found between earlier separation anxiety disorder and subsequent onset of internalizing and externalizing DSM-IV disorders and conversely between these disorders and subsequent onset of separation anxiety disorder. Other consistently significant predictors of lifetime separation anxiety disorder included female gender, retrospectively reported childhood adversities, and lifetime traumatic events. These predictors were largely comparable for separation anxiety disorder onsets in childhood, adolescence, and adulthood and across country income groups. Twelve-month separation anxiety disorder prevalence was considerably lower than lifetime prevalence (1.0% of the total sample; interquartile range=0.2%-1.2%). Severe separation anxiety-related 12-month role impairment was significantly more common in the presence (42.4%) than absence (18.3%) of 12-month comorbidity. CONCLUSIONS: Separation anxiety disorder is a common and highly comorbid disorder that can have onset across the lifespan. Childhood adversity and lifetime trauma are important antecedents, and adverse effects on role function make it a significant target for treatment.
