Objectives: Pregnancy loss (PL) can be a very difficult experience. However, the evidence regarding the prevalence and correlates of psychopathology following PL is inconsistent at best. The present study aimed to assess the prevalence of Post-Traumatic Stress Disorder (PTSD) and Major Depressive Disorder (MDD) following PL, and their differential...

On October 7, 2023 (10/7), Hamas militants brutally attacked Israeli towns and villages surrounding the Gaza Strip, resulting in the killing of more than 1100 people, most of whom were civilians slaughtered in their own homes. The killings occurred under highly traumatic circumstances, including shooting, the burning of homes, hunting down people w...

Background: While autism and trauma were often linked in psychoanalytic theory, very few scientific attempts have been made to explore the associations and comorbidity between the two. Instead, each area has grown separately, yielding large bodies of theoretical and clinical knowledge. Theoretical framework: In this article, we suggest several poss...

Background: The psychological effects of systemic lupus erythematosus (SLE) are tremendous. This pilot mixed-methods randomized controlled trial aimed to evaluate the effects of a mindfulness-based stress reduction (MBSR) adapted protocol on psychological distress among SLE patients. Methods: 26 SLE patients were randomly assigned to MBSR group th...

In DSM-5, the event criterion (criterion A) for PTSD includes indirect exposure as a potential source of PTSD. In light of the revised criterion A, it is now important to reevaluate the concept of “secondary traumatization” vis-á-vis the PTSD diagnosis. I argue that, while including indirect exposure in DSM-5 was an important step forward, there is...

Post-traumatic stress symptoms (PTSS) are a risk factor for using intimate partner aggression (IPA), which has mainly been assessed from the male partner’s perspective. In the current study, we compared the rates and levels of using and experiencing psychological IPA as reported by female spouses of men with PTSS. In addition, we examined the media...

Negative birth experiences are common. It is yet unclear which women may be most at risk already before pregnancy. Childhood trauma and non-autonoumous/unresolved attachment state of mind may affect how women experience giving birth. This study used longitudinal data to test childhood trauma and attachment state of mind as predictors of birth exper...

Objective: Spouses of military combatants often experience adverse outcomes, including posttraumatic stress symptoms (PTSS) in the event of ambiguous loss (AL). AL refers to an uncertain situation regarding a person’s status as alive or as cognitively present. The former ambiguity is categorized by the term physical AL (PAL), which refers to the co...

Complex Posttraumatic Stress Disorder (CPTSD) is a condition resulting from exposure to chronic, interpersonal traumatic events, in which some form of control or power dynamics existed. Its clinical picture includes the main symptom clusters of posttraumatic stress disorder, accompanied by dysregulated emotion, problems in interpersonal relationshi...

Objective: Disclosure of deployment-related experiences among military couples is generally beneficial to mental health and relationship adjustment. Yet, disclosure by the spouse is rarely studied, as are the dyadic associations between disclosure and outcomes in both partners. The present study used a dyadic approach to study the relationship betw...

Background Spouses of ex-combatants often experience psychological distress due to sharing their lives with a partner who endured traumatic experiences, a phenomenon known as “secondary traumatization”. Self-differentiation is the emotional distance one takes, while keeping an amount of togetherness with significant others. The couple's relationshi...

Introduction: The perinatal period (i.e., from conception up to one year postpartum) is a time in life when women may experience increased levels of stress. High levels of maternal stress have been shown to have negative consequences for both the mother and the infant. Although the consequences of maternal stress have already been widely studied, t...

Background: Fibromyalgia (FM) is a pain condition characterized by physical and psychological difficulties. This randomized controlled trial aimed to evaluate the effects of a mindfulness-based stress reduction (MBSR) on FM patients and identify the role of two pain cognitions: psychological inflexibility in pain (PIPS) and pain catastrophizing (PC...

Complex posttraumatic stress disorder (CPTSD) is a term representing the psychopathological implications of exposure to chronic, inter‐personal trauma. These include the main symptoms of PTSD, as well as changes in identity, emotion regulation, and inter‐personal relationships. Self‐harm and dissociation (i.e., disintegration of mental processes) a...

Research shows that traumatic events may shatter people's perceptions and assumptions about the world, potentially resulting in PTSD symptoms as well as a lack of integration of the event into one's narrative and experiencing the self as flawed, fragmented, and incoherent. Metacognition, the ability to reflect upon oneself and others and the use of...

Objective: Quantitative studies examining the occurrence of childbirth-related posttraumatic stress disorder (CB-PTSD) following severe perineal rupture are lacking. The objective of this population-based study was to investigate the prospective associations between the degree of perineal tear during childbirth and CB-PTSD symptoms, when adjusting...

Posttraumatic stress disorder (PTSD) sequelae often have ripple effects on victims' families and spouses. Yet there has been a lag in the development and study of couple therapy for PTSD. To fill this gap, we present here a protocol for a study examining the efficacy of Cognitive Behavioral Conjoint Therapy (CBCT), a 15- session couple therapy prot...

While it is known that fibromyalgia patients often suffer from depression and stress symptoms, there is inconclusive evidence as to why these symptoms occur. The aim of this study is to examine the role of emotion regulation in mental health symptoms among treatment-seeking individuals with fibromyalgia. Ninety-three (93) participants (mean age = 4...

Background: Chronic tic disorders (CTDs) commonly co-occur with other psychiatric disorders. CTDs have been linked to functional impairment and reduction in quality of life. Insufficient research is available on depressive symptoms in patients with CTD, especially children and adolescents, yielding conflicting findings. To investigate the presence...

Birth-related posttraumatic stress symptoms (PTSS) place a significant burden on mothers and their families. The aim was to (1) identify differential profiles of maternal birth-related PTSS; (2) determine the predictive value of established risk factors; (3) examine comorbidity patterns related to depression and anxiety symptoms. As part of the Nor...

Abstract: Background and aims: Breast and ovarian cancers affect the lives of many women worldwide. Female cancer survivors often experience hot flashes, a subjective sensation of heat associated with objective signs of cutaneous vasodilatation and a subsequent drop in core temperature. Breast and Ovarian cancer patients also suffer from sleep diff...

The COVID-19 pandemic has a major impact on mental well-being and interpersonal relationships. Nonetheless, little is known about the complex interactions between one’s overall perceived interpersonal closeness and physiological or psychological aspects of interpersonal functioning. This study aimed to understand the interaction between perceived i...

This systematic review and meta-analysis aimed to determine mean estimates of prevalence rates for fulfilling all diagnostic criteria of posttraumatic stress disorder (PTSD) or at least showing significant levels of posttraumatic stress (PTSS) in relation to the traumatic event of childbirth. For the first time, both mothers and fathers were includ...

The current study longitudinally examined the moderating effects of consuming different types of media (i.e., formal – news; and informal – social media, WhatsApp) in the association between COVID-19 related worries, intolerance of uncertainty (IU) and post-traumatic stress symptoms (PTSS). Data were collected at two time points during July and S...

Autism spectrum disorder is a neurodevelopmental condition characterized by social communication difficulties and restricted, repetitive behaviors. Autism spectrum disorder is highly co-morbid with other neuro-psychiatric disorders such as attention deficit hyperactivity disorder, anxiety, and depression. However, research on post-traumatic stress...

Clinical Impact Statement Following participation in war, more than a quarter of veterans suffer from posttraumatic stress symptoms, such as intrusive dreams, high anxiety, and anger outbursts. These symptoms often also affect their spouses. The current longitudinal study examined the trajectories of spouses’ distress, veterans’ PTSS, and wives’ as...

Background: Despite the immense impact of COVID-19 on mental health, there is a lack of prospective studies examining physiological predictors of current risk factors. Moreover, although physiological processes evidently interact with socio-demographic factors to modulate individuals’ response to a crisis, it remains largely unknown how these compl...

Psychopathology is often studied and treated from an individual-centered approach. However, studies have shown that psychological distress is often best understood from a contextual, environmental perspective. This paper explores the literature on emotional contagion and symptom transmission in psychopathology, i.e., the complex ways in which one p...

As part of their work, police officers often attend stressful crime scenes, and are required to operate while making quick decisions. The role of Israeli police officers is particularly complex, and includes military and security tasks, on top of more conventional police work. Thus, there seems to be a great need for mental health interventions aim...

Despite the unfolding impact of the COVID-19 pandemic on psychological well-being, there is a lack of prospective studies that target physiological markers of distress. There is a need to examine physiological predictors from the pre-pandemic period to identify and treat individuals at-risk. In this study, our aim was to use pre-pandemic markers of...

Ever since the publication of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), there has been a controversy around whether the inclusion of indirect exposure as a potential traumatic event for the diagnosis of posttraumatic stress disorder (PTSD) is justified. The aim of the current study was to examine the va...

Objective: War-related trauma may indirectly affect veterans’ spouses both in terms of secondary posttraumatic stress symptoms (PTSS) and negative perceived health. The present study aimed to examine trajectories of secondary PTSS over a twelve-year period and its association with various measures of subjectively perceived health, among spouses of...

Despite the unfolding impact of the COVID-19 pandemic on psychological well-being, there is a lack of prospective studies that target physiological markers of distress. There is a need to examine physiological predictors from the pre-pandemic period to identify and treat individuals at-risk. Our aim was to use pre-pandemic markers of Autonomic Nerv...

Fibromyalgia (FM), a poorly understood rheumatic condition, is characterized by chronic pain and psychiatric comorbidities, most notably depression and anxiety. Additional symptoms include sleep difficulties, fatigue, and various cognitive impairments. Furthermore, FM is surrounded by social stigma, due to the unclear nature and etiology of this co...

Eating disorders (EDs) are serious psychopathologies characterized by a persistent disturbance in eating or eating-related behavior. Studies have shown EDs’ detrimental consequences not only for patients, but also for their families. Nevertheless, a specific group that has so far been neglected, in both the research and clinical fields, are sibling...

Objective: Research on the psychological toll of the COVID-19 pandemic is being conducted in various countries. This study aimed to examine risk factors for mental health problems among Israeli adults during this crisis. Methods: 204 participants took part in the study. They completed self-report questionnaires assessing perceived stress, anxiety,...

People with Autism Spectrum Disorder show an increased risk of experiencing potentially traumatic events, particularly social victimization. However, Autism Spectrum Disorder and Post-Traumatic Stress Disorder co-occurrence was hardly studied. We examined exposure to potentially traumatic life events and PTSD symptoms in adults with Autism Spectrum...

The Issue: Coronavirus-19 (COVID-19) is transforming every aspect of our lives. Identified in late 2019, COVID-19 quickly became characterized as a global pandemic by March of 2020. Given the rapid acceleration of transmission, and the lack of preparedness to prevent and treat this virus, the negative impacts of COVID-19 are rippling through every...

Objective: War captivity entails severe post-traumatic implications for ex-POWs and their partners. This study examines the role of self-differentiation in secondary traumatization and dyadic adjustment among ex-POWs’ spouses. Methods: 106 spouses of Israeli ex-POWs and 56 matched spouses of ex-combatants completed self-report questionnaires asses...

Background United Nations (UN) personnel address a diverse range of political, social, and cultural crises throughout the world. Compared with other occupations routinely exposed to traumatic stress, there remains a paucity of research on mental health disorders and access to mental healthcare in this population. To fill this gap, personnel from UN...

Background and objectives: Previous research indicates that individuals with Autism Spectrum Disorder (ASD) face an increased risk of experiencing traumatic events. Autistic Traits (AT), characteristic of ASD, are continuously distributed across the general population. Our main objective was to examine the association between AT and PTSD (Post Tra...

Background and Objectives: It has been proposed that self-efficacy plays a critical role in the onset and maintenance of Posttraumatic Stress Disorder (PTSD). This study aimed to test if increasing perceptions of self-efficacy using a false feedback technique about coping abilities prior to a trauma-film paradigm lead to a reduction of visual intru...

The present study had several main aims: 1. To build and evaluate a disorder-specific mindfulness-based therapy protocol for fibromyalgia patients. 2. To examine what are the mechanisms of change through which the protocol works, with a special emphasis on translating generic mindfulness constructs (e.g., awareness, non-reactivity) into pain-relate...

Mindfulness involves the cultivation of conscious awareness and attention, with an emphasis on seeing and accepting things as they are. While mindfulness-based interventions have been widely examined among adults with PTSD, thery were very scarcely studied among traumatized adolescents. In this paper, we address this gap in knowledge. We present ev...

Background: Few studies have longitudinally examined predictors of posttraumatic stress disorder (PTSD) in a nationally representative sample of US veterans. We examined predictors of warzone-related PTSD over a 25-year span using data from the National Vietnam Veterans Longitudinal Study (NVVLS). Methods: The NVVLS is a follow-up study of Vietn...

Background and aims Although studies show that those suffering from autism spectrum disorders (ASD) face an increased risk of exposure to trauma (bullying, physical abuse), the co-morbidity between autistic symptoms/traits and post-traumatic stress disorder (PTSD) was almost entirely neglected by researchers. The aim of this preliminary study is to...

Background and objective Late pregnancy loss (PL) is recognized as a very difficult life experience. Often, PL is regarded as a “feminine” trauma, experienced individually by the woman, thus neglecting the role of the parental dyad in coping with the loss. This study aimed to examine: – the prevalence of PTSD and major depressive disorder (MDD) f...

Psychological effects related to systemic lupus erythematosus (SLE) are tremendous. While a variety of psychological treatments have been applied to assist SLE patients, the effects of mindfulness practice were never documented in SLE. Mindfulness-based psychotherapy includes several techniques, including body-scan, breathing exercises, and full aw...

Background: Although PTSD-major depressive disorder (MDD) co-morbidity is well-established, the vast majority of studies have examined comorbidity at the level of PTSD total severity, rather than at the level of specific PTSD symptom clusters. This study aimed to examine the long-term associations between MDD and PTSD symptom clusters (intrusion,...

A question remains regarding differential effects of exposure-based versus non-exposure-based therapies on specific post-traumatic stress disorder (PTSD) symptom clusters. Traumatized emergency room patients were randomized to receive prolonged exposure (PE) or cognitive therapy (CT) without exposure. PE/CT had no differential effect on individual...

Practitioner points: Despite their different theoretical backgrounds and techniques, the notion that PE and CT (without exposure) target different PTSD symptoms was not confirmed in this study. Thus, both interventions may in fact be equally effective for treating intrusion, avoidance and hyperarousal symptoms. Baseline levels of avoidance, intrus...

IMPORTANCE The long-term course of readjustment problems in military personnel has not been evaluated in a nationally representative sample. The National Vietnam Veterans Longitudinal Study (NVVLS) is a congressionally mandated assessment of Vietnam veterans who underwent previous assessment in the National Vietnam Veterans Readjustment Study (NVVR...

This study prospectively examines the longitudinal course of loneliness, social support, and posttraumatic symptoms (PTS) among Israeli war veterans. Two groups of veterans with and without antecedent combat stress reaction (CSR) were assessed at three points of time during a 20-year period. Veterans with CSR reported higher levels of loneliness co...

Background Delayed-onset posttraumatic stress disorder (DPTSD) has been under medicolegal debate for years. Previous studies examining the prevalence and underlying mechanisms of DPTSD have yielded inconclusive findings. Thus, a question still remains regarding the prevalence and underlying mechanism of this phenomenon. This study examined the clin...

Objective Posttraumatic stress disorder (PTSD) and depression are known to be highly comorbid. However, previous findings regarding the nature of this comorbidity have been inconclusive. This study prospectively examined whether PTSD and depression are distinct constructs in an epidemiologic sample, as well as assessed the directionality of the PTS...

Objective The nature of co-morbidity between posttraumatic stress disorder (PTSD) and depression has been the subject of much controversy. This study addresses this issue by investigating associations between probable PTSD and depressive symptoms in a prospective, longitudinal sample of combat veterans. Method Symptoms of PTSD and depression were...

Objective: Posttraumatic stress disorder (PTSD) and depression are known to be highly comorbid. However, previous findings regarding the nature of this comorbidity have been inconclusive. This study prospectively examined whether PTSD and depression are distinct constructs in an epidemiologic sample, as well as assessed the directionality of the PT...

according to DsM-iV-tR, both an objective and a subjective exposure component (a1 and a2 criteria, respectively) are required in order to qualify for a Posttraumatic stress Disorder (PtsD) diagnosis. one proposed DsM-5 change is that Criterion a be more explicitly defined and made purely objective. the DsM and the iCD appear to be largely products...

The authors evaluated 2 cohorts of individuals from different Israeli communities (Sderot and Otef Aza) that are repeatedly subjected to potentially lethal missile attacks. Although both communities border the Gaza Strip and face similar levels of threat, the authors hypothesized that the Sderot cohort would endorse higher rates of stress-related s...

Terrorism creates lingering anxiety about future attacks. In prior terror research, the conceptualization and measurement of coping behaviors were constrained by the use of existing coping scales that index reactions to daily hassles and demands. The authors created and validated the Coping with Terror Scale to fill the measurement gap. The authors...

Delayed-onset posttraumatic stress disorder (DPTSD) has been under medico-legal debate for years. Previous studies examining the prevalence and underlying mechanisms of DPTSD have yielded inconclusive findings. This study examined the role of social resources and warzone exposure in DPTSD. Six hundred and seventy-five Israeli veterans from the 1982...

This study prospectively examines the longitudinal course of loneliness, social support, and posttraumatic symptoms (PTS) among Israeli war veterans. Two groups of veterans with and without antecedent combat stress reaction (CSR) were assessed at three points of time during a 20-year period. Veterans with CSR reported higher levels of loneliness co...

Attachment orientations are mostly considered to be stable interpersonal patterns. Still, a growing body of literature shows changes in attachment orientations following stressful and traumatic events. This study examined the implications of stressful life events (SLEs) throughout the life cycle in insecure attachment orientations (anxious attachme...

Delayed-onset PTSD has been under medico-legal debate for years. Previous studies examining the prevalence and clinical characteristics of delayed-onset PTSD have yielded inconclusive findings. This study prospectively examines the prevalence and clinical picture of late-onset PTSD among Israeli war veterans. It also evaluates whether or not late-o...

Background: The bi-directional relationships between combat-induced posttraumatic symptoms and family relations are yet to be understood. The present study assesses the longitudinal interrelationship of posttraumatic intrusion and avoidance and family cohesion among 208 Israeli combat veterans from the 1982 Lebanon War. Methods: Two groups of ve...

Although war captivity is a potent pathogen for psychiatric illness, little is known about the long-term trajectories of post-traumatic stress disorder (PTSD) among ex-prisoners of wars (ex-POWs). This study aimed to assess the long-term trajectories of PTSD and their predictors following war captivity. One hundred and sixty four Israeli ex-POWs an...

The underlying mechanisms of delayed-onset PTSD are yet to be understood. This study examines the role of stressful life events throughout the life cycle in delayed-onset PTSD following combat. 675 Israeli veterans from the 1982 Lebanon War, 369 with antecedent combat stress reaction (CSR) and 306 without CSR were assessed prospectively, 1, 2 and 2...

The current study aimed to examine the implications of posttraumatic stress disorder symptoms and emotional sharing in marital adjustment and parental functioning among Israeli veterans of the 1982 Lebanon War. The sample consisted of combat stress reaction (CSR) veterans (n = 264) and non-CSR veterans (n = 209). Results show that traumatized veter...

The aim of this study was to examine the long-term trajectories and interrelationships of posttraumatic stress disorder (PTSD) symptom clusters (intrusion, avoidance, and hyperarousal) in clinical and nonclinical groups of war veterans. Six hundred seventy-five Israeli veterans from the 1982 Lebanon War were assessed. The clinical group consisted o...

War captivity is a highly traumatic experience which sometimes has deleterious effects on both ex-POWs and their wives. This study examined the relationships between posttraumatic stress disorder (PTSD) symptoms and differentiation among male ex-prisoners of war (ex-POWs; n = 103), their wives (n = 82), and comparable controls. Results show that ex...

This study examines the contribution of prewar life events, war exposure, and postwar life events to combat-induced psychopathology among 425 Israeli War veterans from the Lebanon War. Data was collected at two time points (1983 and 2002). The sample included veterans with and without combat stress reaction (CSR). Battle intensity and subjective ex...

This study assesses differences in PTSD rates according to different sets of diagnostic criteria. Two samples have been studied: one comprised of 286 combat stress reaction (CSR) casualties and 218 non-CSR veterans from the Lebanon war (Study 1); the other of 95 ex-POWs and 101 non-POWs from the Yom Kipur war (Study 2). Participants were administer...
