Assessment of Posttraumatic Stress Disorder and Educational Achievement in Sweden

Adaptative Skills and Global Functioning of Unaccompanied Migrant Minors in Europe: A Systematised Review

Objectives

This systematised review aimed to examine European literature reporting data about adaptative skills and global external functioning of unaccompanied minors (UAMs).

Methods

We conducted a systematised screening of four databases (APA PsycINFO Ovid, Medline Ovid ALL, Embase.com and Web Of Science Core Collection) using a research strategy including social, scholarly and behavioural abilities as well as externalising problems associated with the target population of UAMs. Thirty articles were included using pre-defined inclusion and exclusion criteria.

Results

Our review showed that despite high levels of internalising disorders, socio-behavioural and educational adjustment of UAMs remained positive. It demonstrated how this population displays a strong desire for academic success and prosocial behaviours instead of aggressivity in everyday life. Nevertheless, our review drew attention to the strong tendency of UAMs to internalise their disorders and display chronic distress and problematic behaviours which increased with time spent in the host country.

Conclusion

Our study draws attention to the risk of underestimating the real mental health needs of refugees, due to preserved external functioning combined with significant settlement pressures.

Association Between Autism and PTSD Among Adult Psychiatric Outpatients

PURPOSE

Autism Spectrum Disorder (ASD) occurs in 1-1.5% of the general population and possibly in up to 20% of psychiatric outpatients. Post Traumatic Stress Disorder (PTSD) occurs at some point in life in 4% of the general population and in 14-20% of psychiatric outpatients. Knowledge about how PTSD manifests in people with ASD is important in order for it to be correctly diagnosed and intervened for.

METHODS

This study investigated the relationship between PTSD and autism among adult psychiatric outpatients (N = 90) of whom 63 had ASD or subthreshold ASD based on DSM-5 criteria. The study group was subjected to in-depth psychiatric assessments using validated instruments. Diagnosis of PTSD was made based on the Mini International Neuropsychiatric Interview (MINI).

RESULTS

There was a trend towards PTSD being more common among participants with ASD compared to participants without ASD, although significant differences could not be shown in this small sample. 21% of the ASD group had current PTSD, compared to 4% of the study group without ASD. There were no differences between the groups regarding exposure to trauma. There was a trend towards a relationship between number of autism symptoms and hyperarousal symptoms in PTSD. Conversely, the PTSD symptom of irritability/outbursts of anger, was significantly associated with number of autism symptoms.

CONCLUSIONS

A subgroup of psychiatric outpatients with ASD also suffer from PTSD. Hyperarousal symptoms are possibly more prevalent in the presentation of PTSD in individuals/patients with ASD compared to those without ASD.

Evaluating the causal relationship between educational attainment and mental health

We investigate the causal relationship between educational attainment (EA) and mental health using two research designs. First, we compare the relationship between EA and 18 psychiatric diagnoses within sibship in Dutch national registry data (N=1.7 million), thereby controlling for unmeasured familial factors. Second, we apply two-sample Mendelian Randomization, which uses genetic variants related to EA or psychiatric diagnosis as instrumental variables, to test whether there is a causal relation in either direction. Our results suggest that lower levels of EA causally increase the risk of MDD, ADHD, alcohol dependence, GAD and PTSD diagnoses. We also find evidence of a causal effect of ADHD on EA. For schizophrenia, anorexia nervosa, OCD, and bipolar disorder, results were inconsistent across the different approaches, highlighting the importance of using multiple research designs to understand complex relationships such as between EA and mental health.

Societal influence and psychological distress among Indonesian adults in Java on the early Omicron wave of COVID-19

Aim

Changes during the COVID-19 pandemic might create pressure on different people, thus this study aimed to measure respondents' psychological distress during the early phase of the Omicron wave in Java Island.

Methods

A web-based survey on societal influence and COVID-19-related psychological distress was distributed through social media in November-December 2021, and received 396 responses.

Results

This study showed that almost 50% of respondents faced psychological distress during the early phase of the Omicron variant, especially concerning hypervigilance and avoidance. Several sociodemographic factors might contribute to the incidence of psychological distress including comorbidity, age and education.

Conclusion

Taken together, the incidence of COVID-19-related psychological distress was still found in the early phase of the Omicron variant, especially among young adults.

A comparative study of posttraumatic stress disorder in two post-conflict communities in Benue state Nigeria

Background

The attendant long-term mental health consequence of the conflict of various kinds in Nigeria is yet to be thoroughly investigated. The Tiv-Fulani farmer-herdsmen crisis is one such conflict that occurred in 2013/2014 in Guma local government in Benue state.

Aims

This study seeks to find out some years after the crisis, the prevalence difference in posttraumatic stress disorder (PTSD) between a community (Uikpiam) with direct exposure to the conflict and another (Daudu) with indirect exposure, the pattern of distribution of PTSD symptoms and the associate factors of PTSD.

Methods

It is a cross-sectional one that employed a multi-stage cluster sampling method to select 413 participants; 135 from Uikpiam and 278 from Daudu. The study instruments administered included a questionnaire with some socio-demographic variables and an extract from the PTSD module of the Composite International Diagnostic Interview.

Results

The prevalence rate of PTSD was higher in Uikpiam (16.3%) when compared to Daudu (4.3%). A high proportion of sub-threshold symptoms of PTSD was recorded in both communities. An association was found between a lower educational qualification and PTSD (χ2 = 8.373; p = 0.039).

Conclusion

PTSD can be a prolonged mental ill-effect of crisis and proximity to trauma sites increases vulnerability including lower education. This study looked at PTSD only as an outcome of this crisis, but mental health adverse outcomes of the crisis may not be limited to this alone, hence the need for further investigations for relevant stakeholders to act.

One versus two biological parents with mental disorders: Relationship to educational attainment in the next generation

BACKGROUND

Both maternal and, separately, paternal mental illness are associated with diminished academic attainment among children. However, the differential impacts of diagnostic type and degree of parental burden (e.g. one v. both parents affected) on these functional outcomes are unknown.

METHODS

Using the Swedish national patient (NPR) and multi-generation (MGR) registers, 2 226 451 children (1 290 157 parental pairs), born 1 January 1973-31 December 1997, were followed through 31 December 2013. Diagnostic status of all cohort members was defined for eleven psychiatric disorders, and families classed by exposure: (1) parents affected with any disorder, (2) parents affected with a disorder group (e.g. neuropsychiatric disorders), and (3) parents affected with a specific disorder (e.g. ADHD). Pairs were further defined as 'unaffected,' 'single-affected,', or 'dual-affected.' Among offspring, the study evaluated fulfillment of four academic milestones, from compulsory (primary) school through University (college). Sensitivity analyses considered the impact of child's own mental health, as well as parental education, on main effects.

RESULTS

Marked reductions in the odds of achievement were observed, emerging at the earliest levels of schooling for both single-affected [adjusted odds ratio (aOR), 0.50; 95% CI 0.49-0.51] and dual-affected (aOR 0.29, 95% CI 0.28-0.30) pairs and persisting thereafter [aOR range (single), 0.52-0.65; aOR range (dual), 0.30-0.40]. This pattern was repeated for analyses within diagnosis/diagnostic group. Main results were robust to adjustment for offspring mental health and parent education level.

CONCLUSIONS

Parental mental illness is associated with profound reductions in educational attainment in the subsequent generation, with children from dual-affected families at uniquely high risk.

High levels of poor mental health among young men in urban informal settlements in South Africa: a community-based study of social determinants

Informal settlements (high population density areas at the outskirts of urban areas characterized by lack basic amenities) in South Africa are consequences of apartheid regime's discriminatory migrant labour and spatial policy and continue to grow. Living in informal settlements accompanies a mire of social/health challenges that threatens upward mobility, but few studies exist that document drivers of mental health challenges in these settings. We investigated the prevalence and social determinants of poor mental health for young men in informal settlements adjacent to one of the largest cities that is at the heart of HIV endemic in South Africa. This study involved a cross-sectional study with cluster sampling design of 674 young men aged 18-30 years residing in eThekwini informal settlement communities. We assessed the prevalence, and social determinants, of significant depressive (i.e., depression) and post-traumatic stress (i.e., PTS) symptoms using logistic regression. Given the complex survey design of the study, all analyses were adjusted for clustering. The prevalence of depression and PTS in the sample was 46.8% and 14.4% respectively. Results of the multivariable analyses indicated that severe food insecurity (aOR = 2.98, 95% CI:1.70-5.22), crime perpetration (aOR = 1.51, 95% CI:1.05-3.80), severe adverse childhood event (aOR = 2.00, 95% CI: 1.05-3.80), traumatic event exposures (aOR = 2.43, 95% CI:1.56-3.80) and problematic alcohol use (aOR = 1.73, 95% CI:1.20-2.49) were significantly associated with depression. While incomplete secondary education (aOR = 0.45, 95% CI:0.22-0.92), moderate food insecurity (aOR = 2.51, 95% CI:1.04-6.06), traumatic event exposures (aOR = 2.19, 95% CI:1.32-3.64) and problematic alcohol use (aOR = 2.15, 95% CI: 1.24-3.73) were significantly associated with PTS. Our study highlights the exceedingly high levels of poor mental health among young men in informal settlements, with depression and PTS being driven by economic/social conditions. Multilevel interventions that address the individual, interpersonal, and social variables that contribute to poor mental health are needed.

Alzheimer's disease and related dementias among aging veterans: Examining gene-by-environment interactions with post-traumatic stress disorder and traumatic brain injury

INTRODUCTION

Post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) confer risk for Alzheimer's disease and related dementias (ADRD).

METHODS

This study from the Million Veteran Program (MVP) evaluated the impact of apolipoprotein E (APOE) ε4, PTSD, and TBI on ADRD prevalence in veteran cohorts of European ancestry (EA; n = 11,112 ADRD cases, 170,361 controls) and African ancestry (AA; n = 1443 ADRD cases, 16,191 controls). Additive-scale interactions were estimated using the relative excess risk due to interaction (RERI) statistic.

RESULTS

PTSD, TBI, and APOE ε4 showed strong main-effect associations with ADRD. RERI analysis revealed significant additive APOE ε4 interactions with PTSD and TBI in the EA cohort and TBI in the AA cohort. These additive interactions indicate that ADRD prevalence associated with PTSD and TBI increased with the number of inherited APOE ε4 alleles.

DISCUSSION

PTSD and TBI history will be an important part of interpreting the results of ADRD genetic testing and doing accurate ADRD risk assessment.

A multi-country study of the associations between HIV vulnerability status, perception of COVID-19 related stigma and post-traumatic stress symptoms during the first wave of the pandemic

BACKGROUND

This study investigated the associations between COVID-19 related stigma and post-traumatic stress symptoms (PTSS); and the associations between PTSS and COVID-19 related stigma, HIV status, COVID-19 status and key HIV population status.

METHODS

This was a secondary analysis of data of 12,355 study participants generated through an online survey that recruited adults from 152 countries between July and December 2020. The dependent variables were COVID-19-related stigma and PTSS. The independent variables were HIV status (positive/negative), transaction sex (yes/no), use of psychoactive drugs (yes/no), and vulnerability status (transaction sex workers, people who use psychoactive drugs, living with HIV, and COVID-19 status). The confounding variables were age, sex at birth (male/female), level of education, sexual minority individuals (yes/no) and country income level. Multivariable logistic regression analyses were conducted to determine associations between the dependent and independent variables after adjusting for confounders.

RESULTS

There were 835 (6.8%) participants who experienced COVID-19 related stigma during the pandemic and 3,824 (31.0%) participants reported PTSS. Respondents who were living with HIV (AOR: 1.979; 95%CI: 1.522-2.573), tested positive for COVID-19 (AOR: 3.369; 95%CI: 2.692-4.217), engaged in transactional sex (AOR: 1.428; 95%CI: 1.060-1.922) and used psychoactive drugs (AOR: 1.364; 95%CI: 1.053-1.767) had significantly higher odds of experiencing COVID-19 related stigma. Individuals with vulnerability status (AOR:4.610; 95%CI: 1.590-13.368) and who experienced COVID-19 related stigma (AOR: 2.218; 95%CI: 1.920-2.561) had significantly higher odds of PTSS.

CONCLUSION

Individuals with vulnerability status may be at increased risk for COVID-19 related stigma. Key and vulnerable populations who were living with HIV and who experienced stigma may be at a higher risk of experiencing PTSS. Populations at risk for PTSS should be routinely screened and provided adequate support when they contract COVID-19 to reduce the risk for poor mental health during COVID-19 outbreaks and during future health crisis with similar magnitude as the COVID-19 pandemic.

The Posttraumatic Stress Disorder (PTSD) Checklist for DSM-5: A Systematic Review of Existing Psychometric Evidence

The PTSD Checklist for DSM-5 (PCL-5) is a widely used self-rated measure of DSM-5 PTSD symptoms. The goal of this systematic review was to synthesize research on the psychometric properties of the PCL-5 to guide clinical and research applications. We focused on reliability, validity, factor structure, optimal cutoff scores, and sensitivity to clinical change indices. A systematic review of the literature following PRISMA guidelines was conducted using PubMed, PsycINFO, CINAHL, and PTSDpubs with search terms capturing selected psychometric indices of the PCL-5. The inclusion criteria were: peer-reviewed publication in English; primary focus on the PCL-5 psychometrics; empirical study; and study with adult samples. The search yielded 265 studies; 56 papers (amounting to 64 studies) met inclusion criteria and were reviewed. Findings generally indicated evidence for: acceptable internal consistency and test-retest reliability; construct validity; a 7-factor Hybrid Model; recommended cutoff scores between 31-33; and ability to index sensitivity to clinical change. To further advance knowledge and applications of the PCL-5, we need more research on abbreviated versions of the PCL-5, bifactor modeling as applied to the PCL-5, as well as on PCL-5 item difficulty estimates, discrimination parameters, and clinical change score estimates.

Post-traumatic stress disorder in the Canadian Longitudinal Study on Aging: A genome-wide association study

OBJECTIVE

Canada exhibits one of highest lifetime prevalence for post-traumatic stress disorder (PTSD), but the etiology of this debilitating mental health condition still remains largely unknown. This study aims to examine the genetics of PTSD in the Canadian Longitudinal Study on Aging (CLSA) to identify potential genetic factors involved in the development of PTSD.

METHOD

The CLSA sample was screened for primary (PTSD status) and secondary outcomes (avoidance, detachment, guardedness, and nightmares) based on the Primary Care PTSD Screen Scale (PC-PTSD). After GWAS quality control and whole-genome imputation, single-marker, gene-based, and polygenic risk score (PRS) analyses were performed.

RESULTS

Based on available genotype and phenotype data, N = 16,535 individuals were selected for the analyses. While genome-wide analyses did not show significant findings for our primary and secondary outcomes, PRS analyses showed variable levels of association between PC-PTSD items with trauma, major depressive disorder, schizophrenia, bipolar disorder, educational attainment, and insomnia (p < 5e-4).

CONCLUSION

This is the first GWAS of PTSD status and individual PC-PTSD items in a population sample of older adults from Canada. This study was also able to replicate findings from previous studies. Genetic investigations into individual symptom components of PTSD may help untangle the complex genetic architecture of PTSD.

Risk Factors for Developing Concurrent Posttraumatic Stress Injury After Work-Related Musculoskeletal Injury: A Case-Control Study

OBJECTIVE

This study aimed to study risk factors for developing concurrent posttraumatic stress injury (PTSI) among workers experiencing work-related musculoskeletal injury (MSI).

METHODS

A case-control study was conducted using workers' compensation data on injured workers undergoing rehabilitation programs for concurrent MSI and PTSI (cases) and MSI only (controls). A variety of measures known at the time of the compensable injury were entered into logistic regression models.

RESULTS

Of the 1948 workers included, 215 had concurrent MSI and PTSI. Concurrent MSI and PTSI were predicted by type of accident (adjusted odds ratio [OR], 25.8), experiencing fracture or dislocation fracture or dislocation (adjusted OR, 3.7), being public safety personnel (adjusted OR, 3.1), and lower level of education (adjusted OR, 1.9).

CONCLUSIONS

Experiencing a concurrent PTSI diagnosis with MSI after work-related accident and injury appears related to occupation, type of accident, and educational background.

Post-Traumatic Stress Disorder Trajectories the Year after COVID-19 Hospitalization

Background: Coronavirus disease (COVID-19) hospitalization has been related to Post-Traumatic Stress Disorder (PTSD). Available information is limited by insufficient follow-up and lack of longitudinal studies. Baseline factors (e.g., sex; obesity) have been related to PTSD, but post-hospitalization factors have not been studied. Objective: This study aimed to analyse prevalence, baseline, post-discharge factors and possible clinical courses of PTSD after hospitalization for COVID-19. Method: 109 patients (94.7% of the original sample) completed a programme of three follow-up telephone assessments during the year following hospitalization. Data included clinical and sociodemographic factors as well as psychometric tools assessing PTSD, social support, and perception of threat to life (PTL). Mixture model analysis was performed to study the longitudinal course of PTSD symptoms. Chronic (>6 months) PTSD predictors were also analysed. Results: 1-year PTSD period prevalence was 23.9%, peaking at six months; 11% of the patients suffered chronic PTSD. Pre- and post-hospitalization factors influenced the onset and course of PTSD over time. These included working status, PTL, and lack of social support. Interestingly, obesity, pulmonary diseases and family cluster infection seem specifically related to PTSD following COVID-19. Inversely, clinical interventions, older age and male gender were protective. Conclusions: PTSD following COVID-19 hospitalization is common. The analysed demographic, social, clinical, and psychological factors predict PTSD symptomatology over time and can modify odds of a chronic course. Clinicians could better identify cases at risk of a chronic PTSD course. Finally, treatment as usual appeared related to a better outcome and should be proposed to patients with PTSD.

The Hidden Factors Affecting Academic Performance Among Chinese Middle School Students: Traumatic Experience and Posttraumatic Stress Symptoms

Background and Purpose

The role of posttraumatic stress disorder (PTSD) in the path from traumatic exposure (TE) to academic performance (AP) is still not explicitly illustrated. The current study aimed to examine the moderator role of PTSD on the relationship between TE and AP, and then to investigate whether this moderator role is influenced by gender.

Participants and Methods

A sample of Chinese students (n=235) who had experienced the major earthquake of Wenchuan was chosen. PTSD and TE were measured by the Impact of Event Scale – Revised (IES-R) and an earthquake-related experience questionnaire, respectively. AP was collected from their up-to-date general examination. Data for 221 participants (53.4% female; mean age=14.03 years, SD=0.824) were finally included in the analysis. Parsimonious latent-variable interaction analysis and hierarchical regression analysis were adopted to examine the moderator role of PTSD.

Results

The average IES-R score was 27.57 (SD=13.265, range 0–67). The average score for earthquake exposure was 5.86 (SD=2.069, range 1–12). The results showed that both TE and the interaction term of PTSD*TE had significant negative correlations with AP, while PTSD was not associated with AP. Subsequent hierarchical regression analysis found that the relationship of the interaction term and AP was only significant in female students, and a simple slope plot showed a distinct pattern of the moderating effect of PTSD in both genders.

Conclusion

This study supported that PTSD moderated the connection between TE and AP in middle school students who had undergone a major earthquake trauma, which was influenced by gender. Students who experienced major trauma with drastic exposure history and manifested PTSD symptoms need specified intervention to avoid further deterioration in performance in school.
