Exploring changing trends in depression and anxiety among adolescents from 2012 to 2019: Insights from My World repeated cross-sectional surveys.

AIM: Research has indicated a rise in the prevalence of depression and anxiety among adolescents over the past three decades. However, the factors underpinning increases in mental health difficulties remain poorly understood. This study examines psychological, social and environmental risk and protective factors that may explain changes in depression and anxiety among adolescents. METHODS: Data were taken from two nationally representative My World Surveys of adolescents aged 12-19 years in 2012 (N = 5,490) and 2019 (N = 9,844). Survey data on depression and anxiety and a range of potential risk (e.g., alcohol use, psychotic symptoms) and protective factors (e.g., resilience, self-esteem) were assessed at both time points. Multiple group analyses assessed whether the predictive ability of risk/protective factors changed from wave 1 to wave 2. RESULTS: Results showed that the prevalence of depression and anxiety increased significantly between 2012 and 2019, particularly among females. Predictors accounted for between 37% and 61% of the variance in outcomes across waves. While some risk/protective factors were consistent predictors of depression and anxiety at both waves (e.g., bullying, discrimination, optimism), reporting female gender and having higher formal help-seeking tendencies more strongly predicted anxiety at wave 2, while lower self-esteem and lower resilience (personal competence) strongly predicted both depression and anxiety at wave 2. CONCLUSION: Findings highlight the need to prioritize adolescent mental health service provision, especially in females. Self-esteem and resilience are potentially important targets for supporting adolescent mental health. Further research is required to understand the causal factors associated with increases in anxiety and depression.

Severe Dissociative Experiences beyond Detachment in a Large Clinical Sample of Inpatients with Post-Traumatic Stress Disorder: Diagnostic and Treatment Implications.

INTRODUCTION: The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) contains a dissociative subtype of post-traumatic stress disorder (PTSD) characterized by depersonalization and derealization. Yet, there is evidence that dissociative symptoms in PTSD go beyond this kind of detachment dissociation and that some patients present with additional compartmentalization dissociation in the form of auditory-verbal hallucination, amnesia, and identity alteration. METHODS: Hence, in this study, we examined latent profiles of childhood trauma (Childhood Trauma Questionnaire), PTSD (Impact-of-Event Scale-Revised), and pathological dissociation (Dissociative Experiences Scale-Taxon; DES-T) in a large sample of severely traumatized inpatients with PTSD (N = 1,360). RESULTS: Results support a three-class solution of the latent profile analysis with a PTSD class, a dissociative subtype class, and a third class characterized by more complex and more severe dissociative symptoms. Importantly, in our inpatient sample of patients with severe PTSD, the latter class was found to be the most prevalent. Both the exploratory character of our retrospective analysis of clinical routine data and the use of the DES-T limit the generalizability of our findings, which require methodologically more rigorous replication. CONCLUSION: In severe PTSD, dissociative symptoms beyond detachment are highly prevalent. Diagnostic and treatment implications are discussed.

Parental physical activity, parental mental health, children's physical activity, and children's mental health.

Introduction: The benefits of physical activity for mental health and well-being and the associations between parental mental health and children's mental health have been well established. These important issues tend to be examined separately however, and there is limited research on the associations between parent and child physical activity and mental health when all considered together. While family focused practice is recommended to provide support for parents who have mental health problems and their families and includes various components (such as psychoeducation, support for mental health and parenting), promoting physical activity for parents and children is not usually a core component of these interventions. Methods: The Northern Ireland Youth Wellbeing Survey aimed to provide estimates of the prevalence of mental health problems among children and young people. The survey also included questions about parental physical activity, parental mental health, and children's physical activity (for those aged 11-19 years). The main aim of the analysis reported in this article was to explore possible bivariate associations between parent and child physical activity and mental health and also explore these associations when all considered together. Participants were included in the analysis where there were completed interviews for the young person and one of their parents, and both young person and parent provided responses in relation to questions on weekly physical activity (n = 882). Results: The findings highlight the positive associations between parental physical activity and parental mental health, and between children's physical activity and children's mental health. They also explore some of the more complex interactions between these four variables, which suggest that gender may also be an important consideration. There were significant associations between father's physical activity and son's mental health, and son's physical activity and father's mental health. Discussions: These findings suggest that including support for parental physical activity and children's physical activity should be a routine component of family focused mental health interventions. It is important to acknowledge that there may be additional barriers to engaging in physical activity for families where a parent is experiencing mental health problems, and these should also be explored and addressed.

Testing predictions from the memory and identity theory of ICD-11 complex posttraumatic stress disorder: Measurement development and initial findings.

BACKGROUND: The 'Memory and Identity Theory' of ICD-11 Complex Posttraumatic Stress Disorder (CPTSD) was recently published but has not yet been subjected to empirical testing. The objective of this study was to evaluate newly developed measures of memory and identity disturbances and test hypothesized structural relations between these constructs and CPTSD symptoms. METHODS: Self-report data were collected from a nationwide sample of adults living in Ukraine (N = 2050) in September 2023. Exploratory factor analysis was used to assess the latent structure of the newly developed measures, and structural equation modeling was used to test the associations between memory and identity disturbances and CPTSD symptoms. RESULTS: 90 % of participants experienced a lifetime trauma, and 9.2 % screened positive for ICD-11 CPTSD. Results indicated that the newly developed measures of memory and identity problems possessed satisfactory psychometric properties, and all but one of the model-implied structural associations were observed. CONCLUSION: This study provides initial empirical support for the Memory and Identity theory of ICD-11 CPTSD, indicating that the basis of this disorder lies in distinct memory and identity processes. Several effects not predicted by the theory were observed, and these can provide the basis for further model testing and refinement.

Prevalence and risk factors of parental mental health problems: A cross-sectional study.

An understanding of the prevalence and risk factors of parental mental health problems is important for early intervention and prevention measures and shaping services for parents and their children. However, large representative surveys of parental mental health problems and associated risk factors are lacking. The aim of this study was to estimate prevalence rates of parental mental health problems using a standardised measure of psychiatric morbidity (General Health Questionnaire; GHQ-12), in a representative sample of parents and caregivers of children and young people (2-19 years) in Northern Ireland. Further, this study explored associated risk factors of parental mental health problems. A random household survey of parents and children was conducted between June 2019 and March 2020. Parental responses on demographic, economic, familial and psychological measures were collected (N = 2815) and 22% of parents and caregivers screened positive for mental health problems. The STROBE checklist for observational research was adhered to. Multivariate logistic regression indicated that being in receipt of benefits, having poor family support, a history of adverse childhood experiences, a history of exposure to politically motivated violence (the Troubles), and a child with conduct problems and poor health were all independent risk factors of increased parental mental health problems. Findings will help to inform future commissioning and development of services and broaden understanding of the correlates of parental mental health problems.

Development and validation of the caregiver-report version of the international grief questionnaire (IGQ-CG): Results from a Ukrainian sample of parents.

The International Grief Questionnaire (IGQ) is a self-report measure of ICD-11 Prolonged Grief Disorder (PGD) in adults. This study sought to develop and validate a caregiver-report version of the IGQ for children and adolescents aged 7-17 years; the IGQ-Caregiver Version (IGQ-CG). 639 parents living in Ukraine provided data on themselves and one child in their household as part of the "The Mental Health of Parents and Children in Ukraine Study: 2023 Follow-up" study. The latent structure of the scale was tested using confirmatory factor analysis (CFA), while convergent validity was assessed through associations with other mental health correlates. Prevalence rates of probable ICD-11 PGD were estimated. CFA results supported a correlated two-factor model ('core' and 'associated' symptoms) and the internal reliability of the scale scores were acceptable. Convergent validity was supported through significant correlations with internalizing symptoms, while contact with the deceased, time since bereavement, and parental PGD were associated with higher scores on the IGQ-CG latent variables. The prevalence of probable ICD-11 PGD was 1.4%, and amongst those with a lifetime bereavement, the conditional rate was 3.2%. The IGQ-CG produces reliable and valid scores for ICD-11 PGD symptoms in children and adolescents as reported by their caregivers.

Prolonged Grief Disorder (PGD) is recognized as a grief-specific disorder included in the ICD-11. The International Grief Questionnaire (IGQ) is available to assess ICD-11 PGD symptoms in adults. However, there is no self-report measure available to assess ICD-11 PGD symptoms in children and adolescents. The researchers developed and validated a caregiver-report version of the IGQ for children and adolescents; the IGQ-Caregiver Version (IGQ-CG). Researchers found that the IGQ-CG was an accurate and consistent measure of PGD. Results showed that 1.4% of the sample met diagnostic requirements for ICD-11 PGD. The newly developed IGQ-CG can assist in the assessment and treatment of ICD-11 PGD in children and young people.

Development and validation of the caregiver-report version of the international depression questionnaire (IDQ-CG) and international anxiety questionnaire (IAQ-CG).

The International Depression Questionnaire (IDQ) and International Anxiety Questionnaire (IAQ) are self-report measures of ICD-11 single episode depressive disorder (DD) and generalised anxiety disorder (GAD). The present study sought to describe the development and psychometric evaluation of the caregiver-report versions of the IDQ and IAQ for children, referred to as the IDQ-CG and IAQ-CG, respectively. Participants were 639 parents living in Ukraine who provided data on themselves and one child in their household as part of "The Mental Health of Parents and Children in Ukraine Study: 2023 Follow-up" study. The latent structure of the IDQ-CG and IAQ-CG were tested using confirmatory factor analysis (CFA), composite reliability (CR) estimates were estimated, and convergent validity was assessed. Prevalence rates of probable ICD-11 DD and GAD were also estimated. CFA results indicated that the IDQ-CG and IAQ-CG were unidimensional, while the internal reliability of both scales was excellent. Convergent validity was established via associations with external measures of internalizing, externalizing, and attention problems as well as trauma exposure. Factors associated with increased IDQ-CG and IAQ-CG scores included pharmacological support for emotional or behavioural problems, delayed milestone development, being forced to move to another part of Ukraine, serious life disruption due to the war, and having experienced a bereavement. Of the total sample, 1.6% met diagnostic requirements for ICD-11 DD and 5.8% met diagnostic requirements for ICD-11 GAD. This study supports the psychometric properties of the IDQ-CG and IAQ-CG. These measures can be effectively used to identify young people in need of mental health support.

Psychological distress, wellbeing and resilience: modelling adolescent mental health profiles during the COVID-19 pandemic.

There has been concern about adolescent mental health during the pandemic. The current study examined adolescent mental health during the initial phase of the COVID-19 pandemic in the UK. Using indicator of psychological distress, wellbeing and resilience, latent profile analysis was used to identify homogeneous mental health groups among young people aged 13-24 (N = 1971). Multinomial logistic regression was then used to examine which sociodemographic and psychosocial variables predicted latent class membership. Four classes were found. The largest class (Class 1, 37.2%) was characterised by moderate symptomology and moderate wellbeing. Class 2 (34.2%) was characterised by low symptomology and high wellbeing, while Class 3 (25.4%) was characterised by moderate symptomology and high wellbeing. Finally, Class 4 was the smallest (3.2%) and was characterised by high symptomology and low wellbeing. Compared to the low symptomology, high wellbeing class, all other classes were associated with less social engagement with friends, poorer family functioning, greater somatic symptoms, and a less positive model of self. A number of unique associations between the classes and predictor variables were identified. Although around two-thirds of adolescents reported moderate-to-high symptomology, most of these individuals also reported concurrent moderate-to-high levels of wellbeing, reflecting resilience. Furthermore, these findings demonstrate how a more comprehensive picture of mental health can be gained through adopting a dual-continua conceptualisation of mental health that incorporates both pathology and well-being. In this way, at-risk youth can be identified and interventions and resources targeted appropriately.

Enhanced Skills Training in Affective and Interpersonal Regulation versus Treatment as Usual for ICD-11 Complex PTSD: A Pilot Randomised Controlled Trial (The RESTORE Trial).

INTRODUCTION: Complex PTSD (CPTSD) is a relatively new condition in ICD-11. This pilot randomised controlled trial aimed to compare a four-module intervention developed to target all symptoms of ICD-11 CPTSD, namely Enhanced Skills in Affective and Interpersonal Regulation (ESTAIR) with treatment as usual (TAU). The purpose of the study was to assess feasibility, safety, acceptability, and preliminary outcomes at the end of treatment and 3-month follow-up. METHODS: A total of N = 56 eligible veterans with CPTSD were randomised to either ESTAIR (n = 28) or TAU (n = 28). Linear mixed models were conducted to assess CPTSD severity, the primary outcome, as measured by the International Trauma Questionnaire (ITQ). RESULTS: Treatment dropout in ESTAIR and TAU was low and equivalent (18% vs. 11%; χ2 (1) = 1.19, p = 0.275), and study retention was high, supporting the feasibility of the study. No serious adverse effects and very few adverse effects occurred, none of which were deemed related to the study. ESTAIR provided significantly greater reduction in CPTSD severity across time for ITQ PTSD (p < 0.001) and DSO (p < 0.001) symptoms. CPTSD pre-to-post effect sizes for ESTAIR were large (PTSD d = 1.78; DSO d = 2.00). Remission of probable CPTSD diagnosis at post-treatment was substantially greater in ESTAIR compared to TAU with only 13.6% versus 84% (p < 0.001) retaining the diagnosis. CONCLUSION: A trial of ESTAIR versus TAU for the treatment of ICD-11 CPTSD indicates the potential efficacy of ESTAIR as well as its feasibility, safety, and acceptability.

Prevalence and validity of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD: A population-based survey of Hong Kong adults.

The present study aimed to report the prevalence of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in the general adult Hong Kong population, and examine the validity of the Chinese International Trauma Questionnaire (ITQ). This descriptive cross-sectional population-based telephone survey included a representative sample of 1070 non-institutionalized permanent Hong Kong residents ages 18-64 years. Participants provided responses to the Chinese version of the ITQ, and measures of adverse childhood experiences (ACEs), depression, anxiety, and stress. Based on the diagnostic algorithm of the ITQ, 5.9% of the sample screened positive for either CPTSD or PTSD, with CPTSD (4.2%) being more common that PTSD (1.7%). Results of the confirmatory factor analysis indicated the first-order correlated 6-factor model to be the best fitting solution. Symptom cluster summed scores were all positively and significantly correlated with all criterion variables. This investigation established the prevalence rates of ICD-11 PTSD and CPTSD using a general adult population sample in Hong Kong. The Chinese ITQ demonstrated sound factorial validity and concurrent validity. Future research can further characterize ICD-11 PTSD and CPTSD in subgroups using the Chinese ITQ.

Prevalence and correlates of ICD-11 prolonged grief disorder among adults living in Ukraine during the war with Russia.

BACKGROUND: Although high rates of bereavement are evident in war-affected populations, no study has investigated the prevalence and correlates of probable ICD-11 prolonged grief disorder (PGD) under these circumstances. METHODS: Participants were 2050 adults who participated in a nationwide survey exploring the effects of the Ukraine-Russia war on the daily lives and mental health of Ukrainian people. RESULTS: Of the total sample, 87.7% (n = 1797) of people indicated a lifetime bereavement. In the full sample, 11.4% met the diagnostic requirements for probable ICD-11 PGD, and amongst those with a lifetime bereavement, the conditional rate of probable ICD-11 PGD was 13.0%. Significant risk factors of ICD-11 PGD included the recent loss of a loved one (6 months to a year ago), being most affected by a partner or spouse's death, loved one dying in the war, no recent contact with the deceased prior to their death, and meeting depression and anxiety diagnostic requirements. CONCLUSION: The study reveals that a significant percentage of Ukrainian bereaved individuals have probable ICD-11 PGD, and identifying risk factors, particularly war-related losses, will aid in the development of intervention and prevention programs for bereaved adults.

Multiple trauma exposure and psychopathology in Syrian refugees living in Turkey: A latent class analysis.

BACKGROUND: After the Syrian civil war, millions of Syrian refugees migrated to neighboring countries, with the majority settling in Turkey. The prevalence of mental disorders is notably higher among refugee populations. However, prior research on Syrian refugees have mostly used variable-centred approaches which have known limitations. Thus, the present study sought to examine the occurrence and co-occurrence of traumatic experiences among Syrian refugees living in Turkey using latent class analysis (LCA). Additionally, this study aimed to identify the associations between latent class membership and trauma-related psychopathology. METHODS: Participants included 593 Syrian refugees living in Turkey. LCA was used to identify latent classes of trauma exposure. Demographic predictors of the latent classes were examined and associations with PTSD, CPTSD, depression and anxiety were also explored. RESULTS: Three latent classes were identified based on trauma exposure; a "multiple traumas" class, "war and human suffering" class, and "low exposure, combat-exposed" class. Odds of PTSD, CPTSD, depression, or anxiety diagnosis did not differ significantly between classes, with the exception of the "multiple traumas" class who were more likely to meet the criteria for anxiety diagnosis compared to the "low exposure" class. LIMITATIONS: Historic psychiatric symptoms or post-migration stressors could not be accounted for in this study, which may explain the lack of significant differences in most mental health outcomes by trauma exposure class. DISCUSSION: The latent classes identified in this study correspond with previous research regarding trauma in Syrian refugees. However, this study largely failed to find significant differences in mental health diagnoses between classes. Future research should consider the effect of post-migration stressors in refugee populations, which may play a crucial role in mental health outcomes.

Mental health in Ukraine in 2023.

BACKGROUND: Very little is known about the mental health of the adult population of Ukraine following Russia's full-scale invasion in February 2022. In this study, we estimated the prevalence of seven mental health disorders, the proportion of adults screening positive for any disorder, and the sociodemographic factors associated with meeting requirements for each and any disorder. METHODS: A non-probability quota sample (N = 2,050) of adults living in Ukraine in September 2023 was collected online. Participants completed self-report questionnaires of the seven mental health disorders. Logistic regression was used to determine the predictors of the different disorders. RESULTS: Prevalence estimates ranged from 1.5% (cannabis use disorder) to 15.2% (generalized anxiety disorder), and 36.3% screened positive for any of the seven disorders. Females were significantly more likely than males (39.0% vs. 33.8%) to screen positive for any disorder. Disruption to life due to Russia's 2014 invasion of Ukraine, greater financial worries, and having fewer positive childhood experiences were consistent risk factors for different mental health disorders and for any or multiple disorders. CONCLUSION: Our findings show that approximately one in three adults living in Ukraine report problems consistent with meeting diagnostic requirements for a mental health disorder 18 months after Russia's full-scale invasion. Ukraine's mental healthcare system has been severely compromised by the loss of infrastructure and human capital due to the war. These findings may help to identify those most vulnerable so that limited resources can be used most effectively.

ICD-11 post-traumatic stress disorder and complex post-traumatic stress disorder in mental health support-seeking former-serving Australian defence force veterans.

BACKGROUND: ICD-11 complex post-traumatic stress disorder is a more severe condition than post-traumatic stress disorder, and recent studies indicate it is more prevalent among military samples. In this study, we tested the psychometric properties of the International Trauma Questionnaire, assessed the relative prevalence rates of post-traumatic stress disorder and complex post-traumatic stress disorder in the sample population and explored relationships between complex post-traumatic stress disorder and post-traumatic stress disorder and a range of risk factors. METHODS: Survey participants (N = 189) were mental health support-seeking former-serving veterans of the Australian Defence Force (ADF) recruited from primary care. Confirmatory factor analysis was used to test the factorial validity of the International Trauma Questionnaire. RESULTS: The latent structure of the International Trauma Questionnaire was best represented by a two-factor second-order model consistent with the ICD-11 model of complex post-traumatic stress disorder. The International Trauma Questionnaire scale scores demonstrated excellent internal reliability. Overall, 9.1% (95% confidence interval = [4.8%, 13.5%]) met diagnostic requirements for post-traumatic stress disorder and an additional 51.4% (95% confidence interval = [44.0%, 58.9%]) met requirements for complex post-traumatic stress disorder. Those meeting diagnostic requirements for complex post-traumatic stress disorder were more likely to have served in the military for 15 years or longer, had a history of more traumatic life events and had the highest levels of depression, anxiety and stress symptoms. CONCLUSION: The International Trauma Questionnaire can effectively distinguish between post-traumatic stress disorder and complex post-traumatic stress disorder within primary care samples of Australian Defence Force veterans. A significantly greater proportion of Australian Defence Force veterans met criteria for complex post-traumatic stress disorder than post-traumatic stress disorder. Australian military mental health services should adopt the International Trauma Questionnaire to routinely screen for complex post-traumatic stress disorder and develop complex post-traumatic stress disorder specific interventions to promote recovery in Australian Defence Force veterans with complex post-traumatic stress disorder.

Is Dissociation a Fundamental Component of ICD-11 Complex Posttraumatic Stress Disorder?

ICD-11 Complex Posttraumatic Stress Disorder (CPTSD) is a disorder of six symptom clusters including reexperiencing, avoidance, sense of threat, affective dysregulation, negative self-concept, and disturbed relationships. Unlike earlier descriptions of complex PTSD, ICD-11 CPTSD does not list dissociation as a unique symptom cluster. We tested whether the ICD-11 CPTSD symptoms can exist independently of dissociation in a nationally representative sample of adults (N = 1,020) who completed self-report measures. Latent class analysis was used to identify unique subsets of people with distinctive symptom profiles. The best fitting model contained four classes including a "low symptoms" class (48.9%), a "PTSD" class (14.7%), a "CPTSD" class (26.5%), and a "CPTSD + Dissociation" class (10.0%). These classes were related to specific adverse childhood experiences, notably experiences of emotional and physical neglect. The "PTSD," "CPTSD," and "CPTSD + Dissociation" classes were associated with a host of poor health outcomes, however, the "CPTSD + Dissociation" class had the poorest mental health and highest levels of functional impairment. Findings suggest that ICD-11 CPTSD symptoms can occur without corresponding dissociative experiences, however, when CPTSD symptoms and dissociative experiences occur together, health outcomes appear to be more severe.

Responding to concerns related to the measurement of ICD-11 complex posttraumatic stress disorder using the International Trauma Questionnaire.

BACKGROUND: A recent study in this journal by Frewen et al. (2023) provided a critical analysis of the most widely used measure of ICD-11 Complex Posttraumatic Stress Disorder (CPTSD), the International Trauma Questionnaire (ITQ). The article was a thoughtful review and gave voice to several widely held concerns about the nature of CPTSD as it is represented in ICD-11 and measured by the ITQ. The primary concern expressed by Frewen et al. was that the symptom profile of ICD-11 CPTSD, as represented in the ITQ, is too simple and fails to provide adequate coverage of the construct. OBJECTIVE: Despite its quality, the article included several misunderstandings about the nature of ICD-11 CPTSD, and the function of the ITQ, that we wish to clarify. PARTICIPANTS: Not applicable. SETTING: Not applicable. RESULTS: In this article, we provide a description of what ICD-11 PTSD and CPTSD are, a review of the process that led to their inclusion in ICD-11, how the ITQ was developed and refined to measure these constructs. We then provide responses to several of the most important concerns raised by Frewen et al. CONCLUSIONS: We highlight the clinical utility of the ICD-11 descriptions of PTSD and CPTSD and discuss how the ITQ can be used as part of a suite of clinical assessments to accurately describe and understand common experiences of psychological distress that often result from exposure to traumatic life events.

The network structure of psychopathological and resilient responses to the pandemic: A multicountry general population study of depression and anxiety.

Commonly identified patterns of psychological distress in response to adverse events are characterized by resilience (i.e., little to no distress), delayed (i.e., distress that increases over time), recovery (i.e., distress followed by a gradual decrease over time), and sustained (i.e., distress remaining stable over time). This study aimed to examine these response patterns during the COVID-19 pandemic. Anxiety and depressive symptom data collected across four European countries over the first year of the pandemic were analyzed (N = 3,594). Participants were first categorized into groups based on the four described patterns. Network connectivity and symptom clustering were then estimated for each group and compared. Two thirds (63.6%) of the sample displayed a resilience pattern. The sustained distress network (16.3%) showed higher connectivity than the recovery network (10.0%) group, p = .031; however, the resilient network showed higher connectivity than the delayed network (10.1%) group, p = .016. Regarding symptom clustering, more clusters emerged in the recovery network (i.e., three) than the sustained network (i.e., two). These results replicate findings that resilience was the most common mental health pattern over the first pandemic year. Moreover, they suggest that high network connectivity may be indicative of a stable mental health response over time, whereas fewer clusters may be indicative of a sustained distress pattern. Although exploratory, the network perspective provides a useful tool for examining the complexity of psychological responses to adverse events and, if replicated, could be useful in identifying indicators of protection against or vulnerability to future psychological distress.

The International Grief Questionnaire (IGQ): A new measure of ICD-11 prolonged grief disorder.

Prolonged grief disorder (PGD) is included in the 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD-11). This study sought to test the validity and reliability of a new brief measure to screen for ICD-11 PGD-the International Grief Questionnaire (IGQ). The psychometric properties of the IGQ were tested using data collected from two bereaved samples of adults from the United Kingdom (n = 1,012) and Ireland (n = 1,011). Confirmatory factor analysis demonstrated that a correlated two-factor model best captured the latent dimensionality of the IGQ in both samples. Estimates of internal reliability were high, whereas the convergent and concurrent validity of the scale were supported through strong associations with external measures. Measurement invariance and differential item functioning testing showed no statistically significant difference in the latent structure of the IGQ nor the functioning of the IGQ items by age, sex, and nationality. For participants who were bereaved for more than 6 months, the rates of probable PGD derived from the IGQ were 10.9% and 15.3% for the Irish and U.K. samples, respectively. The IGQ is a brief, easy-to-use, self-report screening measure that captures all diagnostic criteria of PGD set forth in the ICD-11. Findings from this study provide initial support for the validity, measurement invariance, and reliability of the IGQ among two national samples.

ICD-11 prolonged grief disorder: Prevalence, predictors, and co-occurrence in a large representative sample.

The International Classification of Diseases has recently defined Prolonged Grief Disorder (PGD) with symptoms such as longing, worry, and intense emotional pain that exceed sociocultural norms more than 6 months after the loss. This study aims to (a) estimate the prevalence of this new diagnostic category, (b) identify its sociodemographic and loss-related predictors, and (c) assess the co-occurrence of PGD with other psychological disorders and substance abuse. A large representative sample of Spanish adults (N = 1498) participated. Several multivariate binary logistic regression and multivariate logistic regression models were used. Results showed a 9.95% prevalence in the total sample. Catholic beliefs were a positive predictor, while higher income and more time since loss significantly decreased the odds of PGD. PGD significantly increased the likelihood of anxiety, depression, somatisation, post-traumatic stress disorder, loneliness and substance use. Our study contributes to assessing the multicultural PGD validity, as our results from a large representative sample are comparable to those in other countries with the PGDS. Our findings have direct implications for the assessment and treatment of bereavement, identifying for practitioners variables that make individuals more vulnerable to PGD. Results highlighted the high co-occurrence of PGD with other psychological illnesses and increased drug use.

Predicting school uptake of The Daily Mile in Northern Ireland- a data linkage study with School Census Data and Multiple Deprivation Measures.

BACKGROUND: Participating in physical activity benefits health, yet a majority of children remain inactive. The Daily Mile™ (TDM) originated in Scotland in 2012 with the aim of increasing primary school children's physical fitness. Despite being a practically feasible and popular initiative, it remains unclear the extent to which schools implement TDM, and whether TDM core principles are adhered to (i.e., run or jog at least 3-days per week). In Northern Ireland it is unknown how many schools regularly participate in TDM, and whether there is an association between TDM participation with school type, school location, size, total number of children attending the school, school deprivation level, and/or motivation as measured by the COM-B model (Capabilities, Opportunities, Motivation model of behaviour). Therefore, this study aimed to quantify the uptake of TDM in Northern Ireland, assess whether schools are following the core principles, and analyse if there is an association between aforesaid demographic factors and TDM participation. METHODS: An online cross-sectional survey was sent to all primary and special education schools in Northern Ireland with the support of the Education Authority for Northern Ireland and the Public Health Agency for Northern Ireland. The survey was completed by the school principal or teacher, and was available from 31st August until 16th December 2022. Survey results were linked with the 2021/2022 Northern Ireland School Census Data and Northern Ireland Multiple Deprivation Measure 2017. Quantitative and qualitative questions were included in the survey to assess participation and implementation of TDM. RESULTS: The survey received 609 school responses. After data cleaning, and removal of duplicates from schools a sample of 358 primary schools (45%) and 19 special education schools (47.5%) was analysed. Over half (54.7%) of primary schools and 36.8% of special education schools reported taking part in TDM. More special education needs schools reported taking part in their own version of an 'active mile' rather than TDM formally, and qualitative findings showed TDM was not perceived as appropriate for many children in special educational settings. There was wide variation in adherence to TDM core principles. A multivariate binary logistic regression model was fitted to the data, but it was not statistically significant (χ2(17) = 22.689, p = .160). However, univariate effects showed that increasing levels on COM-B (Capability) was associated with increased likelihood of TDM participation (OR = 2.506), and Catholic Maintained schools were almost twice as likely as Controlled schools to be delivering TDM (OR = 1.919). There was no association found between deprivation and TDM uptake. CONCLUSION: Encouragingly over 50% of schools in Northern Ireland reported taking part in TDM. However, despite being a low-cost and practically feasible physical activity initiative, further intervention work with sound research methodology is needed to promote adherence to TDM core principles to maximise benefits to children's health. Furthermore, concerted efforts are required to adjust TDM so that it is inclusive for all educational settings, and children's abilities.
