RESUMO

BACKGROUND: It is important to identify molecular features that improve prostate cancer (PCa) risk stratification before radical treatment with curative intent. Molecular analysis of historical diagnostic formalin-fixed paraffin-embedded (FFPE) prostate biopsies from cohorts with post-radiotherapy (RT) long-term clinical follow-up has been limited. Utilizing parallel sequencing modalities, we performed a proof-of-principle sequencing analysis of historical diagnostic FFPE prostate biopsies. We compared patients with (i) stable PCa (sPCa) postprimary or salvage RT, (ii) progressing PCa (pPCa) post-RT, and (iii) de novo metastatic PCa (mPCa). METHODS: A cohort of 19 patients with diagnostic prostate biopsies (n = 6 sPCa, n = 5 pPCa, n = 8 mPCa) and mean 4 years 10 months follow-up (diagnosed 2009-2016) underwent nucleic acid extraction from demarcated malignancy. Samples underwent 3'RNA sequencing (3'RNAseq) (n = 19), nanoString analysis (n = 12), and Illumina 850k methylation (n = 8) sequencing. Bioinformatic analysis was performed to coherently identify differentially expressed genes and methylated genomic regions (MGRs). RESULTS: Eighteen of 19 samples provided useable 3'RNAseq data. Principal component analysis (PCA) demonstrated similar expression profiles between pPCa and mPCa cases, versus sPCa. Coherently differentially methylated probes between these groups identified ~600 differentially MGRs. The top 50 genes with increased expression in pPCa patients were associated with reduced progression-free survival post-RT (p < 0.0001) in an external cohort. CONCLUSIONS: 3'RNAseq, nanoString and 850k-methylation analyses are each achievable from historical FFPE diagnostic pretreatment prostate biopsies, unlocking the potential to utilize large cohorts of historic clinical samples. Profiling similarities between individuals with pPCa and mPCa suggests biological similarities and historical radiological staging limitations, which warrant further investigation.

RESUMO

PURPOSE: Prostate-specific membrane antigen (PSMA) is increasingly used to image prostate cancer in clinical practice. We sought to develop and test a humanised PSMA minibody IAB2M conjugated to the fluorophore IRDye 800CW-NHS ester in men undergoing robot-assisted laparoscopic radical prostatectomy (RARP) to image prostate cancer cells during surgery. METHODS: The minibody was evaluated pre-clinically using PSMA positive/negative xenograft models, following which 23 men undergoing RARP between 2018 and 2020 received between 2.5 mg and 20 mg of IR800-IAB2M intravenously, at intervals between 24 h and 17 days prior to surgery. At every step of the procedure, the prostate, pelvic lymph node chains and extra-prostatic surrounding tissue were imaged with a dual Near-infrared (NIR) and white light optical platform for fluorescence in vivo and ex vivo. Histopathological evaluation of intraoperative and postoperative microscopic fluorescence imaging was undertaken for verification. RESULTS: Twenty-three patients were evaluated to optimise both the dose of the reagent and the interval between injection and surgery and secure the best possible specificity of fluorescence images. Six cases are presented in detail as exemplars. Overall sensitivity and specificity in detecting non-lymph-node extra-prostatic cancer tissue were 100% and 65%, and 64% and 64% respectively for lymph node positivity. There were no side-effects associated with administration of the reagent. CONCLUSION: Intraoperative imaging of prostate cancer tissue is feasible and safe using IR800-IAB2M. Further evaluation is underway to assess the benefit of using the technique in improving completion of surgical excision during RARP.

RESUMO

For many years, transrectal ultrasound-guided (TRUS) prostate biopsies have been performed to establish a histological diagnosis of prostate cancer. This has been the recommended standard of care procedure, but has always carried risks, in particular the risk of post-procedural sepsis, and the associated antibiotic burden and risk of development of antibiotic resistance. Transperineal (TP) prostate biopsies performed under local anaesthetic (LA) have been proposed as a possible solution to these issues, with potentially lower infectious complications, and avoidance of need for antibiotic prophylaxis. The European Association of Urology produced guidance in 2023 with 'weak' recommendations in favour of LATP biopsy as a new standard of care, citing its safety profile. Both the National Institute for Health and Care Excellence in the UK, and the American Urological Association in the United States, have concluded for now that the body of evidence is inadequate and not offered a similar recommendation. We discuss the available evidence, pros and cons of each technique, and the status of current trials in the field. We believe that clinical equipoise remains necessary, given the disparity in national and international guidelines highlighting the need for large randomised controlled trials to answer the question: is LATP biopsy really better than TRUS biopsy?

RESUMO

BACKGROUND: Corrective service workers (CSWs) are at high risk of post-traumatic stress disorder (PTSD) and other mental health problems. Prevalence rates and help-seeking behaviours are under-researched within this population. AIMS: To assess rates of PTSD and distress, and identify predictors of intention to seek help, among workers at an Australian corrective service agency. METHODS: A cross-sectional online survey was used to collect data on staff demographics, employment, PTSD symptoms and current distress. Participants received a tailored feedback report including referral to relevant mental health services (where applicable) and were asked to indicate their likelihood of seeking help. Prevalence data are reported. Binary logistic regression was used to examine relationships between participant characteristics and help-seeking for those with probable PTSD and/or high psychological distress. RESULTS: Participants (n=1001) were predominantly men (56.8%) with a mean age of 46.72 (SD=11.00). Over half (58.0%) were classified as probable PTSD cases, and one-third (33.0%) were experiencing high psychological distress. Around a third (34.3%) of participants with probable PTSD and/or elevated distress indicated they were likely to seek help. Older age and fewer years of service were associated with increased help-seeking intentions. CONCLUSIONS: CSWs were found to be experiencing probable PTSD at higher rates than reported in previous studies. Relatively few intended to seek help from mental health services, despite being provided with personalised screening and feedback along with access to specialised care. Future research should investigate the potential role of organisational support as a facilitator of help-seeking within this population.

RESUMO

The refugee experience is typically characterized by exposure to numerous premigration traumatic events and postmigration stress in the resettlement environment. Refugees' experiences can lead to elevated rates of psychopathology, including posttraumatic stress disorder (PTSD) and depression. Emotion regulation is a key mechanism contributing to mental health outcomes among refugees. This study examined the impact of age on the association between emotion regulation and critical social outcomes relevant to refugee resettlement, such as social engagement and functional impairment. Participants were 1,081 Arabic-, Farsi-, Tamil- and English-speaking adult refugees. Premigration trauma exposure, postmigration stressors, PTSD symptoms, depressive symptoms, emotion regulation, social engagement, and functional impairment were measured. A series of hierarchical regression and Poisson regression analyses revealed emotion dysregulation as a significant predictor of functional impairment, ß = .36, p < .001, and social engagement, Exp B = 0.99, p = .002. A significant interaction between age and emotion dysregulation was associated with both PTSD, ß = .05, p = .048 and depressive symptoms, ß = .06, p = .010, suggesting a stronger positive association between emotion dysregulation and both PTSD and depressive symptom severity for older individuals. Postmigration stressor exposure, emotion dysregulation, and older age are important factors that may negatively impact social engagement and functional impairment in the resettlement environment. Additionally, higher levels of trauma exposure may negatively impact social engagement. These findings have implications for public health and social services in the context of resettled refugee communities.

RESUMO

OBJECTIVE: There is inadequate evidence regarding the symptom profile of people who have posttraumatic stress disorder (PTSD) over time. The goal of this study was to determine the consistency of symptoms in people with PTSD over successive assessments. METHOD: The sample comprised military personnel who participated in the Army Study to Assess Risk and Resilience in Servicemembers. Participants completed the PTSD Checklist, and this sample included those who completed two assessments. RESULTS: There were 1,164 participants with two consecutive PTSD diagnoses. Only 212 (18.2%) of participants reported the same number of symptoms over both timepoints. Intrusive memories, distress to reminders, avoidance, detachment, and sleep problems were among the most reported symptoms at the second assessment not reported initially. CONCLUSIONS: The observed pattern of findings indicate that although PTSD diagnoses often remain consistent over time, the symptoms that comprise this diagnosis can fluctuate. Clinicians should be sensitive to the changing symptoms that PTSD patients can display over time. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

The amygdala is divided into functional subnuclei which have been challenging to investigate due to functional magnetic resonance imaging (MRI) limitations in mapping small neural structures. Hence their role in the neurobiology of posttraumatic stress disorder (PTSD) remains poorly understood. Examination of covariance of structural MRI measures could be an alternate approach to circumvent this issue. T1-weighted anatomical scans from a 3 T scanner from non-trauma-exposed controls (NEC; n = 71, 75 % female) and PTSD participants (n = 67, 69 % female) were parcellated into 105 brain regions. Pearson's r partial correlations were computed for three and nine bilateral amygdala subnuclei and every other brain region, corrected for age, sex, and total brain volume. Pairwise correlation comparisons were performed to examine subnuclei covariance profiles between-groups. Graph theory was employed to investigate subnuclei network topology. Volumetric measures were compared to investigate structural changes. We found differences between amygdala subnuclei in covariance with the hippocampus for both groups, and additionally with temporal brain regions for the PTSD group. Network topology demonstrated the importance of the right basal nucleus in facilitating network communication only in PTSD. There were no between-group differences for any of the three structural metrics. These findings are in line with previous work that has failed to find structural differences for amygdala subnuclei between PTSD and controls. However, differences between amygdala subnuclei covariance profiles observed in our study highlight the need to investigate amygdala subnuclei functional connectivity in PTSD using higher field strength fMRI for better spatial resolution.

RESUMO

BACKGROUND: Childhood adversity (CA) is strongly associated with depression and anxiety in later life. Many adults with a history of CA may have internalized an insecure self-concept, which may contribute to negative evaluations of one's current well-being relative to different standards. Yet, there is lack of research on well-being comparisons in adults with a history of CA. OBJECTIVE: We examined aversive well-being comparisons (i.e., comparisons threatening the comparer's motives) in the context of CA and their predictive value in depression and anxiety beyond self-esteem, emotion regulation, and external control beliefs. Further, we investigated whether well-being comparison processes mediate the relationship between CA and depression and anxiety. PARTICIPANTS AND SETTING: We conducted a two-wave longitudinal study with 942 adult participants (mean age: 31.56 years, SD = 10.49, 18-75 years). METHODS: Participants completed measures of CA, aversive well-being comparisons (social, temporal, counterfactual, and criteria-based comparisons), self-esteem, emotion regulation, and locus of control at two time points, three months apart. RESULTS: CA was significantly linked to more frequent aversive well-being comparisons. These comparisons were associated with greater discrepancies relative to the comparison standard and a more negative affective impact, ultimately contributing to higher levels of subsequent anxiety and depression symptoms. Comparison frequency emerged as key mediator, highlighting potential pathways through which CA affects adult mental health. These associations emerged despite controlling for established variables in this context, namely self-esteem, emotion regulation, and external locus of control. CONCLUSION: Our findings underscore the unique importance of aversive well-being comparisons in individuals with a history of CA.

RESUMO

This article discusses the management of ventricular storm (VS), a condition characterized by recurrent episodes of sustained ventricular tachycardia or fibrillation, which poses a significant risk of mortality. Prompt intervention is crucial, yet surgical options are often limited due to the patient's unstable condition. This case report presents a 47-year-old female who experienced VS during a planned surgical procedure. Despite initial stabilization, she continued to experience life-threatening arrhythmias, prompting the implementation of simultaneous stellate ganglion block (SGB) and thoracic epidural analgesia (TEA) catheters. This combined approach successfully controlled the arrhythmias, allowing for subsequent surgical interventions. The article emphasizes the potential of SGB and TEA as a bridge to definitive therapies for refractory VS, highlighting the need for further research to solidify their role in clinical practice.

RESUMO

Talking about dying when faced with end-of-life may be important for achieving optimal outcomes for young people and their families. Given the lack of research on young people's communication around end-of-life and death, this analogue study examined the role of attachment theory in conversations about dying. Experiment 1 assessed attachment security of 80 healthy young adults and randomised them to receive either an induction that raised awareness of one's attachment figures or a neutral induction, and then primed them with an imagined scenario where they were diagnosed with an incurable illness. Participants then completed a self-report measure of their willingness to discuss end-of-life topics with family, friends, or a psychologist. The experimental attachment induction did not increase willingness to talk about end-of-life concepts. Experiment 2 extended this design and asked participants to describe these conversations and assessed the content of their imagined end-of-life conversations. Experiment 2 replicated the finding that enhancing individuals' awareness of key attachment figures did not increase participants' willingness to engage in end-of-life conversations. However, heightened attachment awareness led participants to talk more about their relationship with the person they were hypothetically talking with. Across both experiments, avoidant attachment tendencies reduced the likelihood that participants receiving the attachment prime would want to engage in end-of-life conversation. Overall, it seems there are important differences between individuals on willingness to talk about death, and this may be influenced by one's attachment style. These results raise implications for the importance of attachment in the therapeutic relationship for healthcare professionals working with young people with life-limiting illnesses, such as cancer. Further research may shed light on how an individually tailored approach, taking into account attachment security, achieves the best outcomes for individuals who require end-of-life conversations.

RESUMO

The current study evaluated the Kiswahili version of General Health Questionnaire (GHQ-12) in a Kenyan context comprising of women exposed to gender-based violence. Participants were randomly drawn from community sampling using household screening methods in peri-urban areas in Nairobi. A total of 1,394 participants with varying levels of literacy (years of education: mean [M] = 9.42; standard deviation [SD] = 3.73) and aged between 18 and 89 years were recruited for the study. The observed factor structure of the GHQ-12 was evaluated using six most tested models querying the dimensionality of the instrument insofar as the impacts of positive and negative wording effects in driving multidimensionality. Results from the confirmatory factor analysis supported a bifactor model, consisting of a general distress factor and two separate factors representing common variance due to the positive and negative wording of items. Overall, the findings support the use of the Kiswahili version of the GHQ-12 as a unidimensional construct with method-specific variance owing to wording effects. Importantly, GHQ-12 responses from a sample of Kenyan women with relatively low levels of literacy are congruent with the factor structure observed in other cross-cultural settings in low- and-middle-income countries.

RESUMO

INTRODUCTION: Forcibly displaced people (FDP) have a high risk of developing mental disorders such as post-traumatic stress (PTS) disorder. Providing adequate mental healthcare for FDP is crucial but despite overall efficacy of many existing interventions, a large proportion of FDP does not benefit from treatment, highlighting the necessity of further investigating factors contributing to individual differences in treatment outcome. Yet, the few studies that have explored moderators of treatment effects are often insufficiently powered. Therefore, the present Individual Patient Data meta-analysis (IPD-MA) will investigate treatment effects and their moderators-variables related to beneficiaries, providers, intervention and study characteristics in relation to PTS outcomes. METHODS AND ANALYSIS: A systematic literature search will be conducted from database inception in the databases PsycINFO, Cochrane, Embase, PTSDpubs and Web of Science. Only studies published in English, German, French, Spanish, Portuguese, and Dutch will be considered. Retrieved records will be screened for eligibility. Randomised controlled trials on adult FDP receiving psychological and psychosocial interventions aimed at alleviating symptoms such as PTS compared with a control condition without intervention will be included in this IPD-MA. Subsequently, authors of eligible studies will be contacted to request individual patient data (IPD). All datasets obtained will be synthesised into one large dataset which will be analysed using a one-stage approach by conducting mixed-effects linear regression models (ie, primary analysis). Additionally, aggregate data meta-analyes will be run using a two-stage approach by conducting multivariate regression models including all IPD (transformed) and available meta-data from study reports (ie, secondary analysis). PTS will serve as primary outcome measure, while mental health outcomes other than PTS, attendance, attrition, treatment non-response and adverse outcomes will be examined as secondary outcomes. ETHICS AND DISSEMINATION: This IPD-MA does not require ethical approval. The results will be published in international peer-reviewed journals. PROSPERO REGISTRATION NUMBER: CRD42022299510.

RESUMO

BACKGROUND: The TRANSLATE (TRANSrectal biopsy versus Local Anaesthetic Transperineal biopsy Evaluation) trial assesses the clinical and cost-effectiveness of two biopsy procedures in terms of detection of clinically significant prostate cancer (PCa). This article describes the statistical analysis plan (SAP) for the TRANSLATE randomised controlled trial (RCT). METHODS/DESIGN: TRANSLATE is a parallel, superiority, multicentre RCT. Biopsy-naïve men aged ≥ 18 years requiring a prostate biopsy for suspicion of possible PCa are randomised (computer-generated 1:1 allocation ratio) to one of two biopsy procedures: transrectal (TRUS) or local anaesthetic transperineal (LATP) biopsy. The primary outcome is the difference in detection rates of clinically significant PCa (defined as Gleason Grade Group ≥ 2, i.e. any Gleason pattern ≥ 4 disease) between the two biopsy procedures. Secondary outcome measures are th eProBE questionnaire (Perception Part and General Symptoms) and International Index of Erectile Function (IIEF, Domain A) scores, International Prostate Symptom Score (IPSS) values, EQ-5D-5L scores, resource use, infection rates, complications, and serious adverse events. We describe in detail the sample size calculation, statistical models used for the analysis, handling of missing data, and planned sensitivity and subgroup analyses. This SAP was pre-specified, written and submitted without prior knowledge of the trial results. DISCUSSION: Publication of the TRANSLATE trial SAP aims to increase the transparency of the data analysis and reduce the risk of outcome reporting bias. Any deviations from the current SAP will be described and justified in the final study report and results publication. TRIAL REGISTRATION: International Standard Randomised Controlled Trial Number ISRCTN98159689, registered on 28 January 2021 and registered on the ClinicalTrials.gov (NCT05179694) trials registry.

RESUMO

Although trauma-focused psychotherapy (T-F psychotherapy) is the treatment of choice for posttraumatic stress disorder (PTSD), up to one half of patients do not respond to this treatment. Attempts to improve response to T-F psychotherapy have focused on augmenting fear extinction-based factors. Here, a systematic and meta-analytic review of predictors of T-F psychotherapy outcome was conducted with the goal of using an aggregate data-driven approach to elucidate baseline factors associated with treatment outcome. There were 114 studies that met inclusion criteria (N = 61, 970; Mage = 40.1 years; 40.1% female). There were 237 effect sizes across 24 meta-analytic categories. Poorer treatment response is associated with lower pretreatment levels of activation of fear-related brain regions, psychophysiological reactivity to fear provocation, trauma-related cognitions, anger, depression, high-risk alleles of genes linked to fear, lower levels of executive control, and social support. A range of other factors also predicted poorer responses including being male, non-Caucasian, older in age, early trauma occurrence, more trauma experience, history of combat trauma, as well as comorbid sleep, pain, poor quality life, and alcohol abuse difficulties. This review provides one potential explanation for the limited success of T-F psychotherapy augmentation strategies that have focused only on fear circuity mechanisms at the exclusion of other factors. Here, poor response relating to predictors of early trauma onset and comorbidity are consistent with clinical presentations of complex PTSD, which may suggest T-F psychotherapy is less effective for this condition. This collective evidence suggests that clinicians should consider a tailored approach that targets potential barriers to successful treatment response.

RESUMO

BACKGROUND: The burden of common mental disorders in low and middle-income countries (LMICs) is growing with little known about how to allocate limited resources to reach the greatest number of people undergoing instances of significant psychological distress. We present a study protocol for a multicentre, parallel-group, superiority, randomised controlled trial. METHODS AND ANALYSIS: Adults with significant psychological distress (K10 score ≥20) will be randomised to receive a stepped care programme involving a self-guided course (Doing What Matters) followed by a more intensive group programme (Problem Management Plus) or the self-guided course alone, both of which will take place in addition to enhanced treatment as usual comprising of a follow-up referral session to available services within the community. We will include 800 participants. An intent-to-treat and completer analysis will explore the impact of the stepped model of care on anxiety and depression symptoms (as measured by the Hopkins Symptom Checklist; HSCL-25) at 24 weeks from baseline. Secondary outcomes include positive psychological well-being, agency, changes in patient-identified problems, quality of life and cost-effectiveness. Linear mixed models will be used to assess the differential impact of the conditions over time. Analyses will focus on the primary outcome (HSCL-25) and secondary outcomes (agency subscale, WHO Well-Being Index, WHO Disability Assessment Schedule V.2.0, EQ-5D, Psychological Outcomes Profiles Scale) for both conditions, with the main outcome time point being the 3-month follow-up, relative to baseline. ETHICS AND DISSEMINATION: This will be the first randomised controlled trial to assess the benefits of a stepped model of care to addressing psychological distress in a LMIC setting. Results will provide important insights for managing limited resources to mental healthcare in these settings and will be accordingly disseminated to service providers and organisations via professional training and meetings, and via publication in relevant journals and conference presentations. We will also present these findings to the Jordanian Ministry of Health, where this institute will guide us on the most appropriate format for communication of findings, including written reports, verbal presentations and/or brochures. Ethical approval was obtained from the University of Jordan School of Nursing Research Ethics Committee (number: PF.22.10).

RESUMO

OBJECTIVE: Evidence on effective prevention of posttraumatic stress disorder (PTSD) is sparse, particularly among first responders. This study evaluated the effectiveness of a Tactical Mind-Body Resilience Training program on PTSD symptoms in first responders. METHOD: Active-duty first responders (n = 80; Mage = 41.8 years, 82.5% men) were randomized to the intervention group or the waitlist control condition. PTSD symptoms as measured by the PTSD-8 were the primary outcome assessed at postintervention and at 3-month follow-up. Secondary outcomes were cognitive and emotional coping strategies, resilience, somatic symptoms, work performance, and sickness absence. RESULTS: At postintervention, the intervention group had significantly reduced PTSD symptoms compared to the control group (d = -0.26, difference = -2.52, 95% confidence interval [CI] [-4.93, -0.11], p = .040); however, this difference was attenuated at 3-month follow-up (d = -0.07, difference = -1.41, 95% CI [-3.83, 1.01], p = .248). The intervention group had significant improvements in cognitive reappraisal and resilience at postintervention compared to the control group, which were sustained at 3 months. The remaining secondary outcomes had statistically nonsignificant improvements. CONCLUSIONS: This workplace-delivered intervention shows potential in preventing the development of PTSD in first responders. Further research is needed on maintaining long-term benefits of this training. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

Background: Appraisals are central to posttraumatic stress disorder (PTSD). Yet, few studies have examined how culture influences the associations between different types of trauma-related appraisals and PTSD symptoms.Objective: This study investigated cultural influences on appraisals of control and their associations with PTSD symptoms.Method: European Australian (n = 140, Mage = 35.80, SD = 12.44; 21 men, 97 women, 20 gender diverse/prefer not to report) and Chinese Australian (n = 129, Mage = 30.16, SD = 8.93, 21 men, 97 women, 20 gender diverse/prefer not to report) trauma survivors completed measures of appraisals, cultural values, and PTSD symptoms.Results: Findings showed that the Chinese Australian group was associated with greater Chinese cultural beliefs about adversity (i.e. emphasizing the value of adversity and people's ability to overcome adversity) and fewer fatalism appraisals (i.e. appraising one's destiny as externally determined), which in turn were atemporally associated with fewer PTSD symptoms; these atemporal indirect associations were moderated by self-construal and holistic thinking. The Chinese Australian group also reported fewer secondary control appraisals (i.e. attempts to change aspects of the self and accept current circumstances), which were atemporally associated with greater PTSD symptoms. In contrast, the European Australian group was associated with fewer primary control appraisals (i.e. perceived ability to personally change or control a situation), which were atemporally associated with greater PTSD symptoms.Conclusion: These findings highlight the importance of considering the influence of culture on appraisals in PTSD. However, it must be noted that causal relationships cannot be inferred from cross-sectional mediation analyses and thus, future longitudinal research is needed.


Chinese Australian trauma survivors were associated with greater reporting of Chinese cultural beliefs about adversity and fewer fatalism appraisals, which were associated with fewer PTSD symptoms. These associations were moderated by a trauma survivor's self-construal and level of holistic thinking.Chinese Australian trauma survivors reported fewer secondary control appraisals, which were associated with greater PTSD symptoms.European Australian trauma survivors were associated with fewer primary control appraisals, which were associated with greater PTSD symptoms.

RESUMO

OBJECTIVE: Refugees show elevated rates of complex posttraumatic stress disorder (CPTSD). However, relatively little is known regarding the psychological mechanisms that underlie the association between exposure to potentially traumatic events (PTEs) and CPTSD following exposure to war, persecution and displacement. In this study, we investigated the potential mediating role of moral injury appraisals (cognitive appraisals regarding the experience and consequences of morally transgressive events) in the association between PTE exposure, posttraumatic stress disorder (PTSD), and disturbances in self-organization (DSO) symptoms. METHOD: Participants were 889 refugees from Arabic-, Farsi-, Tamil-, and English-speaking backgrounds who completed an online survey in their own language at two time points 12 months apart. We assessed PTE exposure, moral injury-other appraisals (appraising moral transgressions as enacted by others), moral injury-self appraisals (appraising moral transgressions as enacted by the self), PTSD symptoms, and DSO symptoms. RESULTS: Longitudinal structural equation modeling indicated that moral injury-other appraisals mediated the association between PTE exposure and both PTSD and DSO symptoms. In contrast, moral injury-self appraisals only mediated the association between PTE exposure and DSO symptoms. CONCLUSIONS: Findings highlight the role of moral injury appraisals in exacerbating traditional PTSD symptoms, as well as the broader symptoms characteristic of CPTSD. Further, results indicate that specific types of moral injury appraisals (relating to one's own and others' perceived moral transgressions) may lead to differential psychological reactions, raising important implications for clinical practice.

RESUMO

BACKGROUND: In humanitarian settings, brief screening instruments for child psychological distress have potential to assist in assessing prevalence, monitoring outcomes, and identifying children and adolescents in most need of scarce resources, given few mental health professionals for diagnostic services. Yet, there are few validated screening tools available, particularly in Arabic. METHODS: We translated and adapted the Child Psychosocial Distress Screener (CPDS) and the Pediatric Symptom Checklist (PSC) and conducted a validation study with 85 adolescents (aged 10-15) in Lebanon. We assessed internal consistency; test-retest reliability; convergent validity between adolescent- and caregiver-report and between the two measures; ability to distinguish between clinical and non-clinical samples; and concurrent validity against psychiatrist interview using the Kiddie Schedule for Affective Disorders and Schizophrenia. RESULTS: The translated and adapted child-reported PSC-17 and PSC-35, and caregiver-reported PSC-35 all showed adequate internal consistency and test-retest reliability and high concurrent validity with psychiatrist interview and were able to distinguish between clinical and non-clinical samples. However, the caregiver-reported PSC-17 did not demonstrate adequate performance in this setting. Child-reported versions of the PSC outperformed caregiver-reported versions and the 35-item PSC scales showed stronger performance than 17-item scales. The CPDS showed adequate convergent validity with the PSC, ability to distinguish between clinical and non-clinical samples, and concurrent validity with psychiatrist interview. Internal consistency was low for the CPDS, likely due to the nature of the brief risk-screening tool. There were discrepancies between caregiver and child-reports, worthy of future investigation. For indication of any diagnosis requiring treatment, we recommend cut-offs of 5 for CPDS, 12 for child-reported PSC-17, 21 for child-reported PSC-35, and 26 for caregiver-reported PSC-35. CONCLUSIONS: The Arabic PSC and CPDS are reliable and valid instruments for use as primary screening tools in Lebanon. Further research is needed to understand discrepancies between adolescent and caregiver reports, and optimal methods of using multiple informants.
