Anxiety, Depression and Post Traumatic Stress Disorder after critical illness: a UK-wide prospective cohort study.

BACKGROUND: Survivors of intensive care are known to be at increased risk of developing longer-term psychopathology issues. We present a large UK multicentre study assessing the anxiety, depression and post-traumatic stress disorder (PTSD) caseness in the first year following discharge from an intensive care unit (ICU). METHODS: Design: prospective multicentre follow-up study of survivors of ICU in the UK. SETTING: patients from 26 ICUs in the UK. INCLUSION CRITERIA: patients who had received at least 24 h of level 3 ICU care and were 16 years of age or older. INTERVENTIONS: postal follow up: Hospital Anxiety and Depression Score (HADS) and the Post-Traumatic Stress Disorder (PTSD) Check List-Civilian (PCL-C) at 3 and 12 months following discharge from ICU. MAIN OUTCOME MEASURE: caseness of anxiety, depression and PTSD, 2-year survival. RESULTS: In total, 21,633 patients admitted to ICU were included in the study. Postal questionnaires were sent to 13,155 survivors; of these 38% (4943/13155) responded and 55% (2731/4943) of respondents passed thresholds for one or more condition at 3 or 12 months following discharge. Caseness prevalence was 46%, 40% and 22% for anxiety, depression and PTSD respectively; 18% (870/4943 patients) met the caseness threshold for all three psychological conditions. Patients with symptoms of depression were 47% more likely to die during the first 2 years after discharge from ICU than those without (HR 1.47, CI 1.19-1.80). CONCLUSIONS: Over half of those who respond to postal questionnaire following treatment on ICU in the UK reported significant symptoms of anxiety, depression or PTSD. When symptoms of one psychological disorder are present, there is a 65% chance they will co-occur with symptoms of one of the other two disorders. Depression following critical illness is associated with an increased mortality risk in the first 2 years following discharge from ICU. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN69112866 .

Validity of the posttraumatic stress disorders (PTSD) checklist in pregnant women.

BACKGROUND: The PTSD Checklist-civilian (PCL-C) is one of the most commonly used self-report measures of PTSD symptoms, however, little is known about its validity when used in pregnancy. This study aims to evaluate the reliability and validity of the PCL-C as a screen for detecting PTSD symptoms among pregnant women. METHODS: A total of 3372 pregnant women who attended their first prenatal care visit in Lima, Peru participated in the study. We assessed the reliability of the PCL-C items using Cronbach's alpha. Criterion validity and performance characteristics of PCL-C were assessed against an independent, blinded Clinician-Administered PTSD Scale (CAPS) interview using measures of sensitivity, specificity and receiver operating characteristics (ROC) curves. We tested construct validity using exploratory and confirmatory factor analytic approaches. RESULTS: The reliability of the PCL-C was excellent (Cronbach's alpha =0.90). ROC analysis showed that a cut-off score of 26 offered optimal discriminatory power, with a sensitivity of 0.86 (95% CI: 0.78-0.92) and a specificity of 0.63 (95% CI: 0.62-0.65). The area under the ROC curve was 0.75 (95% CI: 0.71-0.78). A three-factor solution was extracted using exploratory factor analysis and was further complemented with three other models using confirmatory factor analysis (CFA). In a CFA, a three-factor model based on DSM-IV symptom structure had reasonable fit statistics with comparative fit index of 0.86 and root mean square error of approximation of 0.09. CONCLUSION: The Spanish-language version of the PCL-C may be used as a screening tool for pregnant women. The PCL-C has good reliability, criterion validity and factorial validity. The optimal cut-off score obtained by maximizing the sensitivity and specificity should be considered cautiously; women who screened positive may require further investigation to confirm PTSD diagnosis.

Migraine patients have a higher prevalence of PTSD symptoms in comparison to chronic tension-type headache and healthy subjects: a case-control study.

OBJECTIVE: Headache is one of the most common disorders and has a heavy socioeconomic burden on both patients and society. Previous studies have demonstrated a high prevalence of psychological issues (e.g. depression and anxiety) in headache and especially migraine patients. The current study was designed to evaluate the prevalence of post-traumatic stress disorder (PTSD) symptomatology in chronic migraine (CM), chronic tension-type headache (CTTH) and healthy subjects. MATERIAL AND METHODS: CM and CTTH subjects were selected consecutively from patients referring to the department of neurology clinic at Shafa Hospital, Kerman University of Medical Sciences, Kerman, Iran. PTSD symptomatology was assessed using PTSD checklist civilian version-Persian edition (PCL-C). Control subjects were enrolled from the family members of headache patients who did not have any history of headache. Chi-square test was used to analyse data and p < .05 was considered statistically significant. RESULTS: Of the 60 control subjects, 5 had a PTSD symptomatology (8.3%); this prevalence was 13.3% for CTTH and 40% for CM groups. CM patients had a significantly higher prevalence of PTSD symptomatology in comparison to CTTH and control subjects (p < .05). With reference to gender, most of the subjects with PTSD symptomatology were female. CONCLUSION: Results of the current study demonstrated that CM patients have a higher prevalence of PTSD symptomatology compared to another chronic headache condition (CTTH) and healthy subjects, which should be considered while treating CM patients. Further studies in larger populations are demanded.

Subjective sleep parameters: A marker to PTSD symptoms evolution? A 4-year longitudinal study.

Disturbed sleep is a common feature after exposure to a traumatic event, especially when PTSD develops. However, although there is evidence suggesting a potential role of sleep disturbance in the progression of PTSD symptoms, the interrelationship between sleep and PTSD symptoms has yet to be determined. In order to address this knowledge gap, we have investigated the influence of initial sleep characteristics on the evolution of post-traumatic stress disorder (PTSD) symptoms over 4 years of follow-up among individuals exposed to the Brazilian Kiss nightclub fire. Participants were individuals exposed to the 2013 Kiss nightclub fire in Brazil. Sleep characteristics and PTSD symptoms were measured within the 4 years following the fire by self-report questionnaires, such as The Pittsburgh Sleep Quality Index (PSQI), and PTSD Checklist - Civilian version (PCL-C). Generalized estimating equations (GEE) models were used to examine the longitudinal associations (by estimating the relative effects of initial sleep problems on PTSD symptoms after adjusting for covariates). Comprehensive information concerning socio-demographic factors, health status, and sleep complaints were obtained. A total of 232 individuals were included. In GEE models, no significant interactions were observed between sociodemographic variables and PTSD symptoms in the follow-up period, however, associations were found between PTSD at baseline and the following factors: the female gender, the victim individuals and the existence of prior psychiatric disease. Initial subjective sleep parameters were strongly associated with PTSD symptoms over 4 years, mainly the presence of disturbed dreams (p = 0.012), increased sleep latency (p = 0.029), and reduced sleep duration (p = 0.012). Sleep complaints and PTSD symptoms were common among individuals after the disaster. The current study has found that the presence of sleep complaints, especially increased sleep latency, presence of disturbed dreams and short sleep duration, in the initial presentation after the fire was consistently associated with the perpetration of PTSD symptoms in the next 4 years of follow-up. These findings suggest that interventions addressing these sleep complaints have the potential to reduce the persistence and/or severity of PTSD symptoms.

Evaluation of post-traumatic stress disorder (PTSD) and related comorbidities in clinical studies.

Patients with traumatic brain injury (TBI) of varying severities are experiencing adverse outcomes during and after rehabilitation. Besides depression and anxiety, post-traumatic stress disorder (PTSD) is highly encountered in civilian and military populations. As more prospective and retrospective studies - focused on evaluating new or old psychological therapies in inpatient, outpatient, or controlled environments, targeting patients with PTSD with or without a history of TBI - are carried out, researchers are employing various scales to measure PTSD as well as other psychiatric diagnoses or cognitive impairments that might appear following TBI. We aimed to explore the literature published between January 2010 and October 2021 by querying three databases. Our preliminary results showed that several scales - such as the Clinician-Administered PTSD Scale (CAPS), the Posttraumatic Stress Disorder Checklist Military Version (PCL-M) as well as Specific Version (PCL-S), and Civilian Version (PCL-C) - have been frequently used for PTSD diagnosis and symptom severity. However, heterogeneity in the scales used when assessing and evaluating additional psychiatric comorbidities and cognitive impairments are due to the study aim and therapeutic approaches. Therefore, conducting an intervention focusing on post-TBI PTSD patients requires increased attention to patients' medical history in capturing multiple cognitive impairments and affected neuropsychological processes when designing the study and including validated instruments for measuring primary and secondary neuropsychological outcomes.

COVID-19-related Traumatic Effects and Psychological Reactions among International Students.

OBJECTIVE: The Coronavirus Disease 2019 (COVID-19) pandemic is a public health emergency of international concern and poses a challenge to people's psychological resilience. Students are reported to have greater psychological impacts from COVID-19. This study aimed to survey international students to better understand their traumatic effects and psychological reactions from COVID-19, to develop evidence-driven strategies to reduce adverse psychological impact during the pandemic. METHOD: We conducted an online survey that collected information on the demographics, economic conditions, academic conditions, and health statuses of native Chinese students attending university in the U.S. Psychological impact was assessed by the Post-traumatic Stress Disorder (PTSD) Checklist Civilian Version (PCL-C) and mental health status was assessed by the Depression, Anxiety, and Stress Scale. RESULTS: This study included 261 Chinese international students. In total, 37.5% of respondents' PTSD PCL-C scores measured as moderate or severe. International students who were currently in China facing job-hunting or planning to continue studying abroad, severe economic pressure, and poor self-rated health status were significantly associated with greater PTSD PCL-C scores and higher levels of stress, anxiety, and depression. CONCLUSION: During the COVID-19 pandemic, more than one-third of the respondents rated their PTSD PCL-C score as moderate-to-severe and nearly half of them reported moderate-to-severe anxiety. Our findings identify factors such as future academic plan, economic pressure, and health status are associated with higher levels of psychological impact and worse mental health status. These should receive attention and psychological interventions should be implemented to improve the mental health of international students during the COVID-19 pandemic.

The Influence of Exposure to Natural Disasters on Depression and PTSD Symptoms among Firefighters.

Introduction Firefighters represent an important population for understanding the consequences of exposure to potentially traumatic stressors. Hypothesis/Problem The researchers were interested in the effects of pre-employment disaster exposure on firefighter recruits' depression and posttraumatic stress disorder (PTSD) symptoms during the first three years of fire service and hypothesized that: (1) disaster-exposed firefighters would have greater depression and PTSD symptoms than non-exposed overall; and (2) depression and PTSD symptoms would worsen over years in fire service in exposed firefighters, but not in their unexposed counterparts. METHODS: In a baseline interview, 35 male firefighter recruits from seven US cities reported lifetime exposure to natural disaster. These disaster-exposed male firefighter recruits were matched on age, city, and education with non-exposed recruits. RESULTS: A generalized linear mixed model revealed a significant exposure×time interaction (e coef =1.04; P<.001), such that depression symptoms increased with time for those with pre-employment disaster exposure only. This pattern persisted after controlling for social support from colleagues (e coefficient=1.05; P<.001), social support from families (e coefficient=1.04; P=.001), and on-the-job trauma exposure (coefficient=0.06; e coefficient=1.11; P<.001). Posttraumatic stress disorder symptoms did not vary significantly between exposure groups at baseline (P=.61). CONCLUSION: Depression symptoms increased with time for those with pre-employment disaster exposure only, even after controlling for social support. Posttraumatic stress disorder symptoms did not vary between exposure groups.

Partner abuse and its association with emotional distress: A study exploring LGBTI relationships.

This study examines partner abuse in LBGTI relationships, with focus on the associations with emotional distress and protective factors. Two hundred and eighty-seven participants took part. Partner abuse (victimisation) comprised three factors; conflict orientated aggression; hostile ignorance and control of communication; and social control and possessiveness (including threats to possessions). Perpetration factors were similar. Significant differences across sexuality or gender were limited to the perpetration of abuse relating to suspicion and possessiveness, where men were more likely to report this than the other gender groups, and women were less likely to report this. Of those reporting abuse in their current relationship, over half reported experiencing abuse in a primary relationship previously, with 60% reporting exposure to abuse as a child. Partner abuse in their current relationship predicted current levels of increased emotional distress, with reduced satisfaction with the current relationship having an indirect impact on this association. Resilience traits were not a predictor or mediator. The results demonstrate the similarity in abuse across LGBTI communities despite the diversity of genders, sexualities and experiences within these groups. The results are discussed with regard to directions for future research and implications for practice.

Prevalence and related factors of post-traumatic stress disorder among medical staff members exposed to H7N9 patients.

OBJECTIVE: This study aimed to evaluate the prevalence and related factors of post-traumatic stress disorder (PTSD) symptoms among doctors and nurses who were exposed to H7N9 patients during the H7N9 influenza epidemic. To provide scientific basis for promoting the physical and psychological health of these staff members. METHOD: The 102 medical staff workers who were exposed to H7N9 patients were recruited through convenient sampling between January 2015 and May 2016. We used a self-reported questionnaire, the PTSD Checklist-Civilian Version (PCL-C), to evaluate the PTSD symptoms among doctors and nurses from an intensive care unit (n = 61), a respiratory department (n = 20), and an emergency department (n = 21). We then analyzed the related factors. RESULTS: Around 20.59% of the tested doctors and nurses showed PTSD symptoms. The sample had a mean PCL-C score of 30.00 ± 9.95. The differences in the scores of doctors and nurses with different genders, ages, professional titles, contact frequencies, trainings, and experiences were statistically significant (P < 0.05, P < 0.01). Moreover, t-tests and one-way analysis of variance showed that nurses received higher scores than doctors, female participants received higher scores than male participants, and the participants with low professional title and high contact frequency, aged between 20 years and 30 years, with less than five years of work experience, having not received related training and with no related experience obtained higher PCL-C scores than the others (P < 0.05, P < 0.01). CONCLUSION: The PTSD level of doctors and nurses after their exposure to H7N9 patients was high, which warrant further research. Health and medical institutions should pay attention to the physical and psychological health of these staff members.

Factor Structure and Psychometric Properties of the Posttraumatic Stress Disorder (PTSD) Checklist and DSM-5 PTSD Symptom Set in a Long-Term Postearthquake Cohort in Armenia.

Psychometric properties of the Armenian-language posttraumatic stress disorder (PTSD) Checklist-Civilian version (PCL-C) and the DSM-5 PTSD symptom set were examined in a long-term cohort of earthquake survivors. In 2012, 725 survivors completed the instruments. Item-/scale-level analysis and confirmatory factor analysis (CFA) were performed for both scales. In addition, exploratory factor analysis (EFA) was conducted for DSM-5 symptoms. Also, the differential internal versus external specificity of PTSD symptom clusters taken from the most supported PTSD structural models was examined. Both scales had Cronbach's alpha greater than .9. CFA of PCL-C structure demonstrated an excellent fit by a four-factor (reexperiencing, avoidance, numbing, and hyperarousal) model known as numbing model; however, a superior fit was achieved by a five-factor model (Elhai et al.). EFA yielded a five-factor structure for DSM-5 symptoms with the aforementioned four domains plus a negative state domain. This model achieved an acceptable fit during CFA, whereas the DSM-5 criteria-based model did not. The Armenian-language PCL-C was recommended as a valid PTSD screening tool. The study findings provided support to the proposed new classification of common mental disorders, where PTSD, depression, and generalized anxiety are grouped together as a subclass of distress disorders. Recommendations were made to further improve the PTSD diagnostic criteria.

Stress-related symptoms and positive emotions after a myocardial infarction: a longitudinal analysis.

BACKGROUND: There is a controversy as to whether the diagnostic umbrella of post-traumatic stress reactions is directly applicable to serious health conditions like myocardial infarction (MI). OBJECTIVE: The principal objective of this study was to examine longitudinally the prevalence of posttraumatic stress-related symptoms, throughout three measurement periods, for patients who had suffered a first MI. In addition to the analysis of symptoms related to stress and general distress, the presence of and temporary evolution of positive emotions and optimism in these patients was also evaluated. DESIGN: A longitudinal study with three periods of evaluation after the MI (Time 1 (T1): 48-72 hours, Time 2 (T2): 5 months, and Time 3 (T3): 13 months). RESULTS: In T1 few symptoms related to the stressful event were found. The probable prevalence of PTSD was 8-11% at 5 months after the MI and 0-3% 13 months after the event. With regard to subjective severity of the infarction, although in the first instance patients did not regard the event as excessively traumatic, in the periods T2 and T3 this perception increased significantly [F (2, 32)=20.00; p=0.0001]. At all times during the measurement period the mean positive affect was significantly greater than the negative affect. CONCLUSIONS: As the results show, the probable prevalence of PTSD, as well as the severity of different symptom clusters, is low at all times of the evaluation. The diagnostic implications of these findings are discussed as well as the uses and abuses of diagnostic labels to characterize the psychological experiences lived through after a potentially life-threatening health problem.
