Abstract
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.

Abstract
Introduction Approximately half of individuals with posttraumatic stress disorder (PTSD) may meet criteria for other psychiatric disorders, and PTSD symptoms are associated with diminished health and psychosocial functioning. However, few studies examine the longitudinal progression of PTSD symptoms concurrent with related symptom domains and functional outcomes, such that may neglect important longitudinal patterns of symptom progression beyond PTSD specifically. Methods Therefore, we used longitudinal causal discovery analysis to examine the longitudinal interrelations among PTSD symptoms, depressive symptoms, substance abuse, and various other domains of functioning in five longitudinal cohorts representing veterans (n = 241), civilians seeking treatment for anxiety disorders (n = 79), civilian women seeking treatment for post-traumatic stress and substance abuse (n = 116), active duty military members assessed 0-90 days following TBI (n = 243), and civilians with a history of TBI (n = 43). Results The analyses revealed consistent, directed associations from PTSD symptoms to depressive symptoms, independent longitudinal trajectories of substance use problems, and cascading indirect relations from PTSD symptoms to social functioning through depression as well as direct relations from PTSD symptoms to TBI outcomes. Discussion Our findings suggest PTSD symptoms primarily drive depressive symptoms over time, tend to show independence from substance use symptoms, and may cascade into impairment in other domains. The results have implications for refining conceptualization of PTSD co-morbidity and can inform prognostic and treatment hypotheses about individuals experiencing PTSD symptoms along with co-occurring distress or impairment.

Abstract
Traumatic brain injury (TBI) may lead to impairments in various outcome domains. Since most instruments assessing these are only available in a limited number of languages, psychometrically validated translations are important for research and clinical practice. Thus, our aim was to investigate the psychometric properties of the patient-reported outcome measures (PROM) applied in the CENTER-TBI study. The study sample comprised individuals who filled in the six-months assessments (GAD-7, PHQ-9, PCL-5, RPQ, QOLIBRI/-OS, SF-36v2/-12v2). Classical psychometric characteristics were investigated and compared with those of the original English versions. The reliability was satisfactory to excellent; the instruments were comparable to each other and to the original versions. Validity analyses demonstrated medium to high correlations with well-established measures. The original factor structure was replicated by all the translations, except for the RPQ, SF-36v2/-12v2 and some language samples for the PCL-5, most probably due to the factor structure of the original instruments. The translation of one to two items of the PHQ-9, RPQ, PCL-5, and QOLIBRI in three languages could be improved in the future to enhance scoring and application at the individual level. Researchers and clinicians now have access to reliable and valid instruments to improve outcome assessment after TBI in national and international health care.

Abstract
Military personnel in industrialized societies often develop posttraumatic stress disorder (PTSD) during combat. It is unclear whether combat-related PTSD is a universal evolutionary response to danger or a culture-specific syndrome of industrialized societies. We interviewed 218 Turkana pastoralist warriors in Kenya, who engage in lethal cattle raids, about their combat experiences and PTSD symptoms. Turkana in our sample had a high prevalence of PTSD symptoms, but Turkana with high symptom severity had lower prevalence of depression-like symptoms than American service members with high symptom severity. Symptoms that facilitate responding to danger were better predicted by combat exposure, whereas depressive symptoms were better predicted by exposure to combat-related moral violations. The findings suggest that some PTSD symptoms stem from an evolved response to danger, while depressive PTSD symptoms may be caused by culturally specific moral norm violations.

Abstract
Objective: This study examined the relationship of childhood physical abuse, posttraumatic stress disorder (PTSD), depression, and suicide in patients with PTSD through path analysis. Materials and Methods: A total of 114 patients with PTSD (36 men and 78 women) were recruited and completed psychological assessments including the Childhood Trauma Questionnaire, the scale for suicidal ideation, the clinician-administered PTSD scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the PTSD checklist, and the Hospital Anxiety and Depression Scale. Structural equation modeling was used to evaluate the results. We developed a model including childhood physical abuse experience as the causal variable, suicidal ideation as a result variable, and PTSD and depression as mediation variables. PTSD symptoms were divided into four clusters [intrusion, avoidance, negative cognition and mood, and altered arousal and reactivity (hyperarousal)] to determine predictive power for suicide. Results: PTSD symptoms fully mediated the relationship between childhood physical abuse and suicidal ideation. Furthermore, PTSD symptoms fully mediated the relationship between childhood physical abuse and depression. Among the PTSD symptoms, hyperarousal was the only symptom cluster that mediated the relationship between childhood physical abuse and suicidal ideation. The symptom clusters of negative cognition and mood as well as hyperarousal mediated the relationship between childhood physical abuse and depression. Conclusions: This study presents a link between childhood physical abuse and current symptoms in patients with PTSD, and highlights specific PTSD symptom clusters (i.e., hyperarousal, negative cognition and mood) that may increase the risk for psychopathology later in life.

Abstract
To date, no studies have examined the latent structures of posttraumatic stress disorder (PTSD) within a sample of student veterans. To examine these constructs in a student veteran sample (n = 297), confirmatory factor analysis (CFA) was conducted on six different models of PTSD, including a one-factor model, based on the 20 symptoms found in the DSM-5; PTSD was assessed using the PCL-5. Global fit statistics suggest that fit across all models, including the 1-factor model, were good [RMSEAs(0.054-0.056); CFIs(0.928-0.940); SRMRs(0.043-0.045)], and the AIC was lowest for the seven-factor hybrid model. Statistical tests and fit guidelines for nested models suggest there is no quantitative advantage of a five, six, or seven-factor model over the existing DSM-5 four-factor model. Given the high percentage of student veterans that screened positive for a probable PTSD diagnosis (53 %) in this study compared to non-student veterans (11-20 %) and the general student population (11-15 %) found in other studies, further research is needed to assess the clinical utility of these symptoms and model structures.

Abstract
Identifying the optimal factor structure of posttraumatic stress disorder (PTSD) has recently been reinvigorated in literature due to the substantial changes to its diagnostic criteria in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Currently, six models of PTSD are supported in literature, but there is no consensus on the best-fitting factor structure. Additionally, the extant literature examining the relationship between PTSD symptom-grouping and AS in the latent level has been scarce. The present study's objectives are two-fold: first, we aimed to identify the best-fitted model of PTSD by comparing the six empirically-supported models, and; second, we examined the relationship between the best-fitting model with anxiety sensitivity (AS). Utilizing a sample of 476 combat-exposed soldiers, the results suggest that both the anhedonia and hybrid models provide the best fit to the data, with the anhedonia model achieving slightly better fit indices. Further, the examination on the influence of AS to PTSD reveal that while there is a pattern of decreasing factor loadings and factor correlations when accounting for AS, the changes are not significant to alter the PTSD symptom-structure. Based on these results, our findings suggest further investigation on the possible mediating or moderating mechanisms by which AS may influence PTSD.

Abstract
Although evidence suggests that risk-taking among individuals with co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD) may be precipitated by trauma-related emotional distress, studies have yet to examine moderators of this effect. One moderator worth investigating is recurrent major depressive disorder (MDD), given its influence on emotional responding and subsequent behavior. This study examined the moderating role of recurrent MDD in the relation of PTSD to risk-taking propensity following neutral and trauma scripts among SUD patients. Participants were 193 patients with and without current PTSD and/or recurrent MDD in residential SUD treatment. Risk-taking propensity, as assessed through the Balloon Analogue Risk Task (BART), was evaluated following a neutral script and a personalized trauma script. A significant script by PTSD by recurrent MDD interaction was found. Participants with PTSD and recurrent MDD exhibited significantly lower risk-taking following the trauma script relative to participants with PTSD but no recurrent MDD. Moreover, participants with PTSD and recurrent MDD exhibited a significantly smaller increase in risk-taking following the trauma script (relative to the neutral script) than participants with PTSD but no recurrent MDD. Participants with PTSD and recurrent MDD did not differ significantly from participants without PTSD. Results provide support for the context-dependent nature of risk-taking among PTSD-SUD patients without (vs. with) recurrent MDD. Results also highlight the importance of considering the presence of recurrent MDD in research and/or clinical work with SUD patients with PTSD.

Abstract
Obsessive-compulsive (OC) symptoms have been associated with trauma exposure. Although no studies have specified relations between type of trauma and OC symptom presentations, this information may inform personalized care for this complex population. Thus, this study used profile analysis via multidimensional scaling to characterize typical OC symptom profiles in individuals exposed to interpersonal versus noninterpersonal traumas. Profiles were also correlated with self-reported disgust and mental contamination, which have been related to OC symptoms and interpersonal trauma in prior research. The interpersonal trauma group revealed two profiles: (1) Obsessing (high obsessing, low neutralizing), and (2) Ordering (high ordering, low obsessing). The noninterpersonal trauma group showed two profiles: (1) Hoarding/Ordering (high hoarding and ordering, low washing), and (2) Hoarding Only (high hoarding, low ordering). No significant correlations were found between OC profiles and disgust-related constructs. Clinical implications, limitations, and future directions are explored.

Abstract
Migrant populations are at increased risk for exposure to traumatic life events. Presently, there are no reliable and valid screening instruments for posttraumatic stress disorder (PTSD) among Filipino migrant workers, a population that numbers over 2.3 million worldwide. This study evaluated the psychometric properties of the PTSD Checklist for DSM-5 (PCL-5) in a sample of female Filipino migrant workers in Macao (SAR), China, in two studies. The first examined the reliability (internal and test-retest), convergent validity (with depression, anxiety, and rumination), and discriminant validity (with pain and social support) in a sample of 131 participants. The second study established criterion validity of the PCL-5 using the PTSD module of the Mini-International Neuropsychiatric Interview (MINI), delivered by a female Filipino psychologist as the criterion, in a sample of 100 participants. Results indicated excellent internal consistency (Cronbach's alpha = 0.95) and moderate 10-day test-retest reliability (ρ = 0.58, p < .001). PCL-5 scores correlated strongly with scores on measures of depression (ρ = 0.71, p < .001), anxiety (ρ = 0.61, p < .001), and rumination (ρ = 0.68, p < .001), supporting convergent validity. Discriminant validity was demonstrated by a weaker association with scores on measures of pain (ρ = 0.33, p < .001) and social support (ρ = -0.11, p = .22). The diagnostic accuracy of the scale was good (AUC = 0.87). The optimal cutoff score of 25 optimized sensitivity (0.89) while maintaining adequate specificity (0.73), with a weighted Kappa of κ[1]) = 0.82. Our results demonstrated that the PCL-5 is a reliable and valid screening instrument for use among female Filipino migrant workers.

UCLA PTSD reaction index for DSM-5 (PTSD-RI-5): a psychometric study of adolescents sampled from communities in eleven countries. Eur J Psychotraumatol 2019; 10:1605282. [PMID: 31105904 PMCID: PMC6507911 DOI: 10.1080/20008198.2019.1605282] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2019] [Revised: 03/22/2019] [Accepted: 03/28/2019] [Indexed: 12/12/2022] Open
Abstract
Background: Children and adolescents are often exposed to traumatic events, which may lead to the development of posttraumatic stress disorder (PTSD). It is therefore important for clinicians to screen for potential symptoms that can be signs of PTSD onset. PTSD in youth is a worldwide problem, thus congruent screening tools in various languages are needed. Objective: The aim of this study was to test the general psychometric properties of the Traumatic Stress Disorder Reaction Index for children and adolescents (UCLA PTSD) Reaction Index for DSM-5 (PTSD-RI-5) in adolescents, a self-report instrument intended to screen for trauma exposure and assess PTSD symptoms. Method: Data was collected from 4201 adolescents in communities within eleven countries worldwide (i.e. Brazil, Bulgaria, Croatia, Indonesia, Montenegro, Nigeria, Palestine-Gaza, Philippines, Portugal, Romania, and Serbia). Internal consistency, discriminant validity, and a confirmatory factor analysis of a four-factor model representing the main DSM-5 symptoms of the PTSD-RI-5 were evaluated. Results: The PTSD-RI-5 total score for the entire sample shows very good reliability (α = .92) as well as across all countries included (α ranged from .90 to .94). The correlations between anxiety/depressive symptoms and the PTSD-RI-5 scores were below .70 indicating on good discriminant validity. The four-factor structure of the scale was confirmed for the total sample and data from six countries. The standardized regression weights for all items varied markedly across the countries. The lack of a common acceptable model across all countries prevented us from direct testing of cross-cultural measurement invariance. Conclusions: The four-factor structure of the PTSD-RI-5 likely represents the core PTSD symptoms as proposed by the DSM-5 criteria, but there could be items interpreted in a conceptually different manner by adolescents from different cultural/regional backgrounds and future cross-cultural evaluations need to consider this finding.

Abstract
Despite the broad literature base on factor analysis best practices, research seeking to evaluate a measure's psychometric properties frequently fails to consider or follow these recommendations. This leads to incorrect factor structures, numerous and often overly complex competing factor models and, perhaps most harmful, biased model results. Our goal is to demonstrate a practical and actionable process for factor analysis through (a) an overview of six statistical and psychometric issues and approaches to be aware of, investigate, and report when engaging in factor structure validation, along with a flowchart for recommended procedures to understand latent factor structures; (b) demonstrating these issues to provide a summary of the updated Posttraumatic Stress Disorder Checklist (PCL-5) factor models and a rationale for validation; and (c) conducting a comprehensive statistical and psychometric validation of the PCL-5 factor structure to demonstrate all the issues we described earlier. Considering previous research, the PCL-5 was evaluated using a sample of 1,403 U.S. Air Force remotely piloted aircraft operators with high levels of battlefield exposure. Previously proposed PCL-5 factor structures were not supported by the data, but instead a bifactor model is arguably more statistically appropriate.

Abstract
An increasing number of studies investigated the latent factor structure of posttraumatic stress disorder (PTSD) symptomatology following the new fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). To date, there is no consensus on the best representation of PTSD. This study examined six latent PTSD models in a sample of Filipino post-disaster relocatees (N = 523). Further investigation on the relationship of the best-fitting model to generalized anxiety disorder (GAD) in the latent level was conducted. The seven-factor hybrid model consisting of intrusion, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal, was the best fitting model. Latent associations between the factors in the hybrid model and GAD suggest there are core and transdiagnostic features of PTSD. These findings have implications for understanding the underlying mechanism of PTSD and can inform the development of trauma-related interventions, particularly among post-disaster relocatees.

Abstract
Latent factor structure of Secondary Traumatic Stress (STS) has been examined using Diagnostic Statistic Manual-IV (DSM-IV)'s Posttraumatic Stress Disorder (PTSD) nomenclature. With the advent of Diagnostic Statistic Manual-5 (DSM-5), there is an impending need to reexamine STS using DSM-5 symptoms in light of the most updated PTSD models in the literature. The study investigated and determined the best fitted PTSD models using DSM-5 PTSD criteria symptoms. Confirmatory factor analysis (CFA) was conducted to examine model fit using the Secondary Traumatic Stress Scale in 241 registered and practicing Filipino nurses (166 females and 75 males) who worked in the Philippines and gave direct nursing services to patients. Based on multiple fit indices, the results showed the 7-factor hybrid model, comprising of intrusion, avoidance, negative affect, anhedonia, externalizing behavior, anxious arousal, and dysphoric arousal factors has excellent fit to STS. This model asserts that: (1) hyperarousal criterion needs to be divided into anxious and dysphoric arousal factors; (2) symptoms characterizing negative and positive affect need to be separated to two separate factors, and; (3) a new factor would categorize externalized, self-initiated impulse and control-deficit behaviors. Comparison of nested and non-nested models showed Hybrid model to have superior fit over other models. The specificity of the symptom structure of STS based on DSM-5 PTSD criteria suggests having more specific interventions addressing the more elaborate symptom-groupings that would alleviate the condition of nurses exposed to STS on a daily basis.

Abstract
The present study examined the factor structure of six competing posttraumatic stress disorder (PTSD) models based on the recent changes in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in a sample that, while highly vulnerable to PTSD, very few studies have focused on-Asians, particularly Filipino internally displaced persons (IDPs). In recognition of the role of culture in PTSD factor structure, we also investigated the associations of the factors of the best-fitting model with self-construal. A sample of 460 IDPs in government resettlement communities participated in the study. Results of confirmatory factor analyses revealed the seven-factor hybrid model composed of intrusion, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal as the best-fitting model. Furthermore, it was found that associations between independent self-construal and PTSD factors were higher than that of interdependent self-construal and PTSD factors.

Abstract
In the present study, we examined posttraumatic stress disorder (PTSD) symptoms and posttraumatic growth (PTG) responses among a nonclinical sample of 202 participants. Instruments included the PTSD Checklist for the DSM-5 (fifth edition of the Diagnostic and Statistical Manual of Mental Disorders) and Posttraumatic Growth Inventory. Confirmatory factor analysis demonstrated the most support for the 6-factor DSM-5 PTSD model and 5-factor PTG model, previously supported in the literature. Canonical correlation analysis evidenced a strong relationship between PTSD and PTG subscales. Path analysis results demonstrated that PTSD's re-experiencing subscale was related to PTG's appreciation for life subscale. Posttraumatic stress disorder's avoidance was related to PTG's personal strength subscale. We also tested curvilinear relationships between PTSD and PTG subscales. Results and implications are discussed in the context of the constructs of PTSD and PTG.

Abstract
PURPOSE The objective of this study was to evaluate the relationship between factors of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) using confirmatory factor analysis (CFA) in order to further our understanding of the substantial comorbidity between these two disorders. METHODS CFA was used to examine which factors of PTSD's dysphoria model were most related to AUD in a military sample. Ohio National Guard soldiers with a history of overseas deployment participated in the survey (n = 1215). Participants completed the PTSD Checklist and a 12-item survey from the National Survey on Drug Use used to diagnosis AUD. RESULTS The results of the CFA indicated that a combined model of PTSD's four factors and a single AUD factor fit the data very well. Correlations between PTSD's factors and a latent AUD factor ranged from correlation coefficients of 0.258-0.285, with PTSD's dysphoria factor demonstrating the strongest correlation. However, Wald tests of parameter constraints revealed that AUD was not more correlated with PTSD's dysphoria than other PTSD factors. CONCLUSIONS All four factors of PTSD's dysphoria model demonstrate comparable correlations with AUD. The role of dysphoria to the construct of PTSD is discussed.

Abstract
BACKGROUND The current study investigated the underlying dimensionality of DSM-5 posttraumatic stress disorder (PTSD) symptoms in a trauma-exposed Chinese adolescent sample using a confirmatory factor analytic (CFA) alternative model approach. METHODS The sample consisted of 559 students (242 females and 314 males) ranging in age from 12 to 18 years (M = 15.8, SD = 1.3). Participants completed the PTSD Checklist for DSM-5, the Major Depression Disorder and Panic Disorder subscales of the Revised Children's Anxiety and Depression Scale, and the Aggressive Behavior subscale of the Youth Self-Report. RESULTS Confirmatory factor analytic results indicated that a seven-factor model comprised of intrusion, avoidance, negative affect, anhedonia, externalizing behavior, anxious arousal, and dysphoric arousal factors emerged as the best-fitting model. Further analyses showed that the external measures of psychopathological variables including major depressive disorder, panic disorder, and aggressive behavior were differentially associated with the resultant factors. CONCLUSIONS These findings support and extend previous findings for the newly refined seven-factor hybrid model, and carry clinical and research implications for trauma-related psychopathology.

Abstract
BACKGROUND The posttraumatic stress disorder (PTSD) literature is replete with investigations of factor structure, however, few empirical studies have examined discriminant validity and the moderating role of gender on factor structure and symptom expression. This study aimed to address these gaps. METHODS An online, population-based study of 3175 Australian adults was conducted. This study analyzed data from 642 participants who reported a traumatic event. Overall, 10.2% (13.4% females, 7.6% males) met diagnostic criteria for current PTSD. RESULTS Confirmatory factor analyses indicated that eight factor models provided excellent fit to the data. The DSM-5 model, anhedonia and hybrid models provided strong fit to the data, based on statistical fit indices and parsimony. The models' factors were significantly associated with a number of external correlates. Factor structure was gender invariant for the three models, albeit significant latent mean-level differences were apparent in relation to the intrusion/re-experiencing and alterations in arousal and reactivity factors. Bonferroni-adjusted Wald chi-square tests indicated significant gender differences in four DSM-5 PTSD symptoms: females reported significantly higher rates of negative beliefs, diminished interest, restricted affect and sleep disturbance symptoms compared to men. LIMITATIONS Response rate to the survey was low. However, the number of respondents who completed the survey was high and population weights were employed to account for self-selection biases and aid generalizability. CONCLUSIONS The findings provide support for the DSM-5, anhedonia and hybrid models compared to alternative models based on DSM-5 symptoms. Discriminant validity analyses indicated similar patterns of significant associations with the transdiagnostic factors, potentially suggesting that all the PTSD factors are related to non-specific distress. Further research investigating how gender influences PTSD symptom expression is warranted, including possible gender differences in symptom item interpretation.

Abstract
Alternative symptom profiles for posttraumatic stress disorder (PTSD) are presented in the DSM-5 and ICD-11. This study compared DSM-5 PTSD symptom profiles with ICD-11 PTSD symptom profiles among a large group of trauma-exposed individuals from Denmark. Covariates, and rates of co-occurrence with other psychiatric disorders were also investigated. A sample of treatment-seeking adult survivors of childhood sexual abuse (n=434) were assessed using self-report measures of PTSD and other psychiatric disorders. A significantly larger proportion of individuals met caseness for DSM-5 PTSD (60.0%) compared to ICD-11 PTSD (49.1%). This difference was largely attributable to low endorsement of the ICD-11 re-experiencing criteria. Replacement of the 'recurrent nightmares' symptom with the 'recurrent thoughts/memories' symptom seemed to balance the proportion of individuals meeting caseness for both taxonomies. Levels of co-occurrence with anxiety and thought disorder were higher for the DSM-5 model of PTSD compared to the ICD-11 model. Current results merit careful consideration in the selection of symptom indicators for the new ICD model of PTSD, particularly with respect to the re-experiencing symptom category.

Abstract
Gratitude, the tendency to appreciate positive occurrences in one's life that can be partially attributed to another person, has been shown to be a robust predictor of greater well-being. Researchers have also found gratitude to be inversely related to several emotional disorders, including major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). Both of these emotional disorders are highly comorbid and share dysphoric symptoms (e.g., restricted affect, detachment, anhedonia) that could account for deficits in the experience and expression of gratitude. We used confirmatory factor analysis to test the relationships between gratitude and the symptom factors of PTSD (using the DSM-5 model) and MDD in a sample of trauma-exposed college students (N=202). Results indicated that gratitude is more strongly related to PTSD's negative alterations in mood and cognition (NAMC) factor than to other PTSD factors. Implications of these findings for the study of gratitude and trauma are discussed, including whether gratitude and gratitude-based interventions might prove particularly suited to targeting depressive symptoms.

Abstract
The factor structure of posttraumatic stress disorder (PTSD) has been widely researched, but consensus regarding the exact number and nature of factors is yet to be reached. The aim of the current study was to systematically review the extant literature on PTSD's latent structure in the Diagnostic and Statistical Manual of Mental Disorders (DSM) in order to identify the best-fitting model. One hundred and twelve research papers published after 1994 using confirmatory factor analysis and DSM-based measures of PTSD were included in the review. In the DSM-IV literature, four-factor models received substantial support, but the five-factor Dysphoric arousal model demonstrated the best fit, regardless of gender, measurement instrument or trauma type. The recently proposed DSM-5 PTSD model was found to be a good representation of PTSD's latent structure, but studies analysing the six- and seven-factor models suggest that the DSM-5 PTSD factor structure may need further alterations.

Abstract
By analyzing data yielded from a sample of Chinese adolescents surviving a high-intensity earthquake, this study investigated the underlying dimensionality of DSM-5 PTSD symptoms. The sample included 743 traumatized middle school students (396 females and 332 males) aged 11-17 years (mean=13.6, SD=1.0). Results of confirmatory factor analysis showed that an intercorrelated seven-factor model comprised of intrusion, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal factors provided a significant better representation of DSM-5 PTSD symptoms than other alternative models. Further analyses indicated that external measures of major depression disorder and panic disorder symptoms displayed unique associations with four PTSD factors. The findings provide further support for the newly proposed seven-factor model of DSM-5 PTSD symptoms, add to very limited empirical knowledge on the latent structure of DSM-5 PTSD symptoms among adolescents, and carry implications for further refinement of the current classifications of PTSD symptoms and further clinical practice and research on posttraumatic stress symptomatology.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are frequently comorbid. One explanation for this comorbidity is that PTSD has a constellation of "dysphoria" symptoms resembling depression. METHOD Using confirmatory factor analysis we tested the role of DSM-5 PTSD׳s dysphoria factor in relation to MDD symptom dimensions of somatic and non-somatic psychopathology. 672 Ohio National Guard soldiers completed DSM-5 measures of PTSD and MDD symptoms in an epidemiological study. RESULTS Results indicated that in contrast to other PTSD factors, PTSD׳s dysphoria factor was more related to MDD׳s somatic and non-somatic factors. LIMITATIONS Limitations include generalizability to the epidemiological population of trauma-exposed military veterans rather than civilians, and reliance on self-report measures. CONCLUSIONS Implications concerning clinical psychopathology and comorbidity of PTSD are discussed, including whether PTSD should be refined by removing its non-specific symptoms.

Abstract
Several revisions to the symptom clusters of posttraumatic stress disorder (PTSD) have been made in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Central to the focus of this study was the revision of PTSD's tripartite structure in DSM-IV into four symptom clusters in DSM-5. Emerging confirmatory factor analytic (CFA) studies have suggested that DSM-5 PTSD symptoms may be best represented by one of two 6-factor models: (1) an Externalizing Behaviors model characterized by a factor which combines the irritability/anger and self-destructive/reckless behavior items; and (2) an Anhedonia model characterized by items of loss of interest, detachment, and restricted affect. The current study conducted CFAs of DSM-5 PTSD symptoms assessed using the PTSD Checklist for DSM-5 (PCL-5) in two independent and diverse trauma-exposed samples of a nationally representative sample of 1484 U.S. veterans and a sample of 497 Midwestern U.S. university undergraduate students. Relative fits of the DSM-5 model, the DSM-5 Dysphoria model, the DSM-5 Dysphoric Arousal model, the two 6-factor models, and a newly proposed 7-factor Hybrid model, which consolidates the two 6-factor models, were evaluated. Results revealed that, in both samples, both 6-factor models provided significantly better fit than the 4-factor DSM-5 model, the DSM-5 Dysphoria model and the DSM-5 Dysphoric Arousal model. Further, the 7-factor Hybrid model, which incorporates key features of both 6-factor models and is comprised of re-experiencing, avoidance, negative affect, anhedonia, externalizing behaviors, and anxious and dysphoric arousal symptom clusters, provided superior fit to the data in both samples. Results are discussed in light of theoretical and empirical support for the latent structure of DSM-5 PTSD symptoms.

Abstract
OBJECTIVE A dissociative subtype has been recognized based on the presence of experiences of depersonalization and derealization in relation to DSM-IV posttraumatic stress disorder (PTSD). However, the dissociative subtype has not been assessed in a community sample in relation to the revised DSM-5 PTSD criteria. Moreover, the 20-item PTSD Checklist for DSM-5 (PCL-5) currently does not assess depersonalization and derealization. METHOD We therefore evaluated two items for assessing depersonalization and derealization in 557 participants recruited online who endorsed PTSD symptoms of at least moderate severity on the PCL-5. RESULTS A five-class solution identified two PTSD classes who endorsed dissociative experiences associated with either 1) severe or 2) moderate PTSD symptom severity (D-PTSD classes). Those in the severe dissociative class were particularly likely to endorse histories of childhood physical and sexual abuse. A principal axis factor analysis of the symptom list identified six latent variables: 1) Reexperiencing, 2) Emotional Numbing/Anhedonia, 3) Dissociation, 4) Negative Alterations in Cognition & Mood, 5) Avoidance, and 6) Hyperarousal. CONCLUSIONS The present results further support the presence of a dissociative subtype within the DSM-5 criteria for PTSD.

Abstract
BACKGROUND Diagnostic criteria for Posttraumatic Stress Disorder (PTSD) have been revised for DSM-5. Two key changes include alteration of the clustering of PTSD symptoms and new PTSD symptom criteria related to negative alterations in cognition and mood. In this study, we empirically investigated these changes. METHODS We interviewed 325 adolescents and young adults who survived the 2011 youth camp shooting at Utøya Island, Norway. The UCLA PTSD Reaction Index for DSM-IV was used to assess symptoms of PTSD. In addition, 11 questions were added to assess the four new symptom criteria within the new DSM-5 symptom categories. RESULTS PTSD prevalence did not differ significantly whether DSM-IV (11.1%) or DSM-5 (11.7%) criteria were used and the Cohen׳s Kappa for consistency between the diagnoses was 0.061. Confirmatory factor analyses showed that the four-factor structure of the DSM-5 fit the data adequately according to the conceptual model outlined. LIMITATIONS The homogeneity of this sample of highly exposed subjects may preclude generalization to less severely exposed groups. Also, we did not assess criterion G in regard to symptoms causing clinically significant distress and functional impairment. CONCLUSION The prevalence of PTSD was quite similar regardless of diagnostic system. The relatively low concordance between the diagnoses has implications for eligibility for a diagnosis of PTSD.

Abstract
Posttraumatic stress disorder (PTSD) is a significant problem among Iraq/Afghanistan-era veterans. To date, however, there has been only limited research on how the recent changes in DSM-5 influence the prevalence and factor structure of PTSD. To address this key issue, the present research used a modified version of a gold-standard clinical interview to assess PTSD among a large sample of Iraq/Afghanistan-era veterans (N = 414). Thirty-seven percent of the sample met DSM-5 criteria for PTSD compared to a rate of 38% when DSM-IV diagnostic criteria were used. Differences in rates of diagnosis between DSM-IV and DSM-5 were primarily attributable to changes to Criterion A and the separation of the "avoidance" and "numbing" symptoms into separate clusters. Confirmatory factor analysis (CFA) was used to compare the fit of the previous 3-factor DSM-IV model of PTSD to the 4-factor model specified in DSM-5, a 4-factor "dysphoria" model, and a 5-factor model. CFA demonstrated that the 5-factor model (re-experiencing, active avoidance, emotional numbing, dysphoric arousal, anxious arousal) provided the best overall fit to the data, although substantial support was also found for the 4-factor DSM-5 model. Low factor loadings were noted for two of the symptoms in the DSM-5 model (psychogenic amnesia and reckless/self-destructive behavior), raising questions regarding the adequacy of fit between these symptoms and the other core features of PTSD. Overall, findings suggest the DSM-5 model of PTSD is an improvement over the previous DSM-IV model of PTSD, but still may not represent the true underlying factor structure of PTSD.

Abstract
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.

Abstract
BACKGROUND The definition of post-traumatic stress disorder (PTSD) underwent substantial changes in the 2013 edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). How this will affect estimates of prevalence, whether clinical utility has been improved, and how many individuals who meet symptom criteria according to the previous definition will not meet new criteria is unknown. Updated screening instruments, including the PTSD checklist (PCL), have not been compared with previously validated methods through head-to-head comparisons. METHODS We compared the new 20-item PCL, mapped to DSM-5 (PCL-5), with the original validated 17-item specific stressor version (PCL-S) in 1822 US infantry soldiers, including 946 soldiers who had been deployed to Iraq or Afghanistan. Surveys were administered in November, 2013. Soldiers alternately received either of two surveys that were identical except for the order of the two PCL versions (911 per group). Standardised scales measured major depression, generalised anxiety, alcohol misuse, and functional impairment. RESULTS In analysis of all soldiers, 224 (13%) screened positive for PTSD by DSM-IV-TR criteria and 216 (12%) screened positive by DSM-5 criteria (κ 0·67). In soldiers exposed to combat, 177 (19%) screened positive by DSM-IV-TR and 165 (18%) screened positive by DSM-5 criteria (0·66). However, of 221 soldiers with complete data who met DSM-IV-TR criteria, 67 (30%) did not meet DSM-5 criteria, and 59 additional soldiers met only DSM-5 criteria. PCL-5 scores from 15-38 performed similarly to PCL-S scores of 30-50; a PCL-5 score of 38 gave optimum agreement with a PCL-S of 50. The two definitions showed nearly identical association with other psychiatric disorders and functional impairment. CONCLUSIONS Our findings showed the PCL-5 to be equivalent to the validated PCL-S. However, the new PTSD symptom criteria do not seem to have greater clinical utility, and a high percentage of soldiers who met criteria by one definition did not meet the other criteria. Clinicians need to consider how to manage discordant outcomes, particularly for service members and veterans with PTSD who no longer meet criteria under DSM-5.

Abstract
The current study investigated the underlying dimensions of DSM-5 PTSD symptoms in an epidemiological sample of Chinese earthquake survivors. The sample consisted of 810 females and 386 males, with a mean age of 47.9 years (SD=10.0, range: 16-73). PTSD symptoms were assessed using the PTSD Checklist for DSM-5, and alternative models were evaluated with confirmatory factor analysis. Results indicated that a six-factor model comprised of intrusion, avoidance, negative affect, anhedonia, dysphoric arousal, and anxious arousal factors emerged as the best fitting model. The current findings add to limited literature on the latent structure of PTSD symptoms described in the recently released DSM-5, and carry implications for further trauma-related research and clinical practice.

Abstract
BACKGROUND Intimate partner violence (IPV) has been known to adversely affect the mental health of victims. Research has tended to focus on the mental health impact of physical violence rather than considering other forms of violence. OBJECTIVE To systematically review the literature in order to identify the impact of all types of IPV victimisation on various mental health outcomes. METHOD A systematic review of 11 electronic databases (2004-2014) was conducted. Fifty eight papers were identified and later described and reviewed in relation to the main objective. RESULTS Main findings suggest that IPV can have increasing adverse effects on the mental health of victims in comparison with those who have never experienced IPV or those experiencing other traumatic events. The most significant outcomes were associations between IPV experiences with depression, posttraumatic stress disorder, and anxiety. Findings confirm previous observations that the severity and extent of IPV exposure can increase mental health symptoms. The effect of psychological violence on mental health is more prominent than originally thought. Individual differences such as gender and childhood experience of violence also increase IPV risk and affect mental health outcomes in diverse ways. CONCLUSIONS Psychological violence should be considered as a more serious form of IPV which can affect the mental health of victims. Experiencing more than one form of IPV can increase severity of outcomes. Researchers should look at IPV as a multi-dimensional experience. A uniformed definition and measure of IPV could help advance knowledge and understanding of this disparaging global issue.
