Serotonin transporter gene,childhood emotional abuse and cognitive vulnerability to depression

Meta‐analyses evaluating the association between the serotonin transporter polymorphism (5‐HTTLPR) with neuroticism and depression diagnosis as phenotypes have been inconclusive. We examined a gene–environment interaction on a cognitive vulnerability marker of depression, cognitive reactivity (CR) to sad mood. A total of 250 university students of European ancestry were genotyped for the 5‐HTTLPR, including SNP rs25531, a polymorphism of the long allele. Association analysis was performed for neuroticism, CR and depression diagnosis (using a self‐report measure). As an environmental pathogen, self‐reported history of childhood emotional abuse was measured because of its strong relationship with depression. Participants with the homozygous low expressing genotype had high CR if they had experienced childhood emotional maltreatment but low CR if they did not have such experience. This interaction was strongest on the Rumination subscale of the CR measure. The interaction was not significant with neuroticism or depression diagnosis as outcome measures. Our results show that 5‐HTTLPR is related to cognitive vulnerability to depression. Our findings provide evidence for a differential susceptibility genotype rather than a vulnerability genotype, possibly because of the relatively low levels of abuse in our sample. The selection of phenotype and environmental contributor is pivotal in investigating gene–environment interactions in psychiatric disorders.     

Predictors for self‐directed aggression in Italian prisoners include externalizing behaviors,childhood trauma and the serotonin transporter gene polymorphism 5‐HTTLPR

Suicidal behavior and self‐mutilation can be regarded as the expression of self‐directed aggression and both are common in prison populations. We investigated the influence of externalizing behaviors, depressive symptoms, childhood trauma, 5‐HTTLPR variants on self‐directed aggression (N = 145) in a group of 702 male Italian prisoners. Participants were comprehensively evaluated, including for psychiatric disorders, impulsive traits, lifetime aggressive behavior [Brown‐Goodwin Lifetime History of Aggression (BGHA)], hostility, violent behavior during incarceration, depressive symptomatology [Hamilton Depression Rating Scale (HDRS)], childhood trauma [Childhood Trauma Questionnaire (CTQ)]. Logistic regression analysis showed false discovery rate corrected independent main effects of externalizing behaviors: BGHA (P = 0.001), violent behavior in jail (P = 0.007), extraversion (P = 0.015); HDRS (P = 0.0004), Axis I disorders (P = 0.015), CTQ (P = 0.004) and 5‐HTTLPR genotype (P = 0.02). Carriers of 5‐HTTLPR high (L_AL_A), intermediate (L_AL_G, SL_A) activity variants were more likely to have exhibited self‐directed aggression relative to the low activity (L_GL_G, SL_G, SS) variant: high/low: odds ratio (OR) = 2.3, 95% confidence interval (CI) 1.27–4.68, P = 0.007; intermediate/low: OR = 1.96, 95% CI 1.09–3.68, P = 0.025. The CTQ main effect was driven by physical abuse. There was no interactive effect of 5‐HTTLPR and CTQ. Secondary logistic regression analyses in (1) all suicide attempters (N = 88) and (2) all self‐mutilators (N = 104), compared with controls showed that in both groups, childhood trauma (P = 0.008–0.01), depression (P = 0.0004–0.001) were strong predictors. BGHA, violent behavior in jail predicted self‐mutilation (P = 0.002) but not suicide attempts (P = 0.1). This study was able to distinguish differing influences on self‐directed aggression between groups of closely related predictor variables within the externalizing behavioral domain. 5‐HTTLPR had an independent, variant dosage effect.     

Rapid modulation of TRH and TRH-like peptide release in rat brain and peripheral tissues by prazosin

Hyperresponsiveness to norepinephrine contributes to post-traumatic stress disorder (PTSD). Prazosin, a brain-active blocker of α₁-adrenoceptors, originally used for the treatment of hypertension, has been reported to alleviate trauma nightmares, sleep disturbance and improve global clinical status in war veterans with PTSD. Thyrotropin-releasing hormone (TRH, pGlu-His-Pro-NH₂) may play a role in the pathophysiology and treatment of neuropsychiatric disorders such as major depression, and PTSD (an anxiety disorder). To investigate whether TRH or TRH-like peptides (pGlu-X-Pro-NH₂, where “X” can be any amino acid residue) participate in the therapeutic effects of prazosin, male rats were injected with prazosin and these peptides then measured in brain and endocrine tissues. Prazosin stimulated TRH and TRH-like peptide release in those tissues with high α₁-adrenoceptor levels suggesting that these peptides may play a role in the therapeutic effects of prazosin.     

Maternal childhood adversity and child temperament: An association moderated by child 5‐HTTLPR genotype

We examined transgenerational effects of maternal childhood adversity on child temperament and a functional promoter polymorphism, 5‐HTTLPR, in the serotonin‐transporter gene (SLC6A4) as potential moderators of such maternal influences in 154 mother–child dyads, recruited into a longitudinal birth cohort study. We examined the interactive effects of maternal childhood experience using an integrated measure derived from Childhood Trauma Questionnaire (CTQ) and Parental Bonding Index (PBI). Triallelic genotyping of 5‐HTTLPR was performed. A measure of ‘negative emotionality/behavioural dysregulation’ was derived from the Early Childhood Behaviour Questionnaire at 18 and 36 months. Negative emotionality/behavioural dysregulation was highly stable between 18 and 36 months and predicted psychosocial problems at 60 months. After controlling multiple demographics as well as both previous and concurrent maternal depression there was a significant interaction effect of maternal childhood adversity and offspring 5‐HTTLPR genotype on child negative emotionality/behavioural dysregulation (β = 1.03, t_11,115 = 2.71, P < .01). The results suggest a transgenerational effect of maternal developmental history on emotional function in the offspring, describing a pathway that likely contributes to the familial transmission of vulnerability for psychopathology.     

A high risk twin study of combat-related PTSD comorbidity.

Combat-related posttraumatic stress disorder (PTSD) is highly comorbid with other mental disorders. However, the nature of the relationship between PTSD and other mental disorders remains unclear. A discordant high-risk twin design was used on data from a sub-sample of the male-male twin pair members of the Vietnam Era Twin Registry to examine whether patterns of comorbidity are consistent with a psychopathological response to combat exposure or reflect familial vulnerability to psychopathology. Mental disorders were assessed via the Mental Health Diagnostic Interview Schedule Version III - Revised. Discordant monozygotic within-pair comparisons revealed that PTSD probands had higher symptom counts and diagnostic prevalences of mood and anxiety disorders than their non-combat exposed co-twins. Monozygotic co-twins of PTSD probands had significantly more mood disorder symptoms than monozygotic co-twins of combat controls or dizygotic co-twins of veterans with PTSD. These findings suggest that a) major depression, generalized anxiety disorder and panic disorder are part of a post-combat response syndrome; b) a shared familial vulnerability also contributes to the association between PTSD and major depression, PTSD and dysthymia, and c) this shared vulnerability is mediated by genetic factors.     

Correlation of sleep disturbances, anxiety and depression in Croatian war veterans with posttraumatic stress disorder

The aim of the study was to examine the relationships between global sleep quality and its specific components and Posttraumatic Stress Disorder (PTSD) symptom severity questionnaire. We also researched whether sleep quality and sleep disturbances differed among groups of PTSD based on symptom severity categories. This study was conducted on the sample of 120 Croatian war veterans with PTSD. The following self-report instruments were used: Pittsburgh Sleep Quality Index, the Pittsburgh Sleep Quality Index Addendum for PTSD, the Mississippi Scale for Combat-Related PTSD, the Spielberger State and Trait Anxiety Inventory and the Beck Depression Inventory. There were statistically significant differences between the three PTSD severity groups on general nervousness (PSQI-A variable), where patients with extremely severe PTSD have more symptoms of general nervousness than groups with severe or moderate PTSD. Differences were found between PTSD severity groups in episodes of terror and acting-out dreams, where patients with extremely severe PTSD have more symptoms of episodes of terror and acting-out dreams than groups with severe or moderate PTSD. Sleep quality was significantly correlated with state anxiety, trait anxiety, and depression, indicating that with decrease of anxiety and depression, sleep quality improves. Sleep latency was positively correlated with both state and trait anxiety. There wasn't any significant correlation between sleep latency and depression. Study suggests that sleep disturbances are equally severe across groups of veterans based on PTSD severity and that the severity of sleep disturbances is significantly related to severity of anxiety and depression symptoms.

Post‐traumatic stress disorder and beyond: an overview of rodent stress models

Post‐traumatic stress disorder (PTSD) is a psychiatric disorder of high prevalence and major socioeconomic impact. Patients suffering from PTSD typically present intrusion and avoidance symptoms and alterations in arousal, mood and cognition that last for more than 1 month. Animal models are an indispensable tool to investigate underlying pathophysiological pathways and, in particular, the complex interplay of neuroendocrine, genetic and environmental factors that may be responsible for PTSD induction. Since the 1960s, numerous stress paradigms in rodents have been developed, based largely on Seligman's seminal formulation of ‘learned helplessness’ in canines. Rodent stress models make use of physiological or psychological stressors such as foot shock, underwater trauma, social defeat, early life stress or predator‐based stress. Apart from the brief exposure to an acute stressor, chronic stress models combining a succession of different stressors for a period of several weeks have also been developed. Chronic stress models in rats and mice may elicit characteristic PTSD‐like symptoms alongside, more broadly, depressive‐like behaviours. In this review, the major existing rodent models of PTSD are reviewed in terms of validity, advantages and limitations; moreover, significant results and implications for future research—such as the role of FKBP5, a mediator of the glucocorticoid stress response and promising target for therapeutic interventions—are discussed.     

Use of a Portable Biofeedback Device to Improve Insomnia in a Combat Zone,a Case Report

Insomnia is a common problem in situations of stress. Some forms of stress, however, may contraindicate the use of traditional, pharmacological interventions. Working in a combat zone is such a situation. Alternative means of improving sleep are clearly needed for Service Members. We report a case involving a medical provider who was serving in a military, emergency-services facility in Iraq, and who presented with anxiety, depressed mood, and insomnia. Symptoms were sub-threshold for major depressive disorder or acute stress disorder. Mood and anxiety symptoms responded to traditional therapy techniques, but problems with insomnia remained. The patient was given a portable biofeedback device that employs an infrared sensor photoplethysmograph to measure heart rate variability (HRV) from peripheral finger pulse. One week later, sleep was significantly improved. Symptom improvement lasted to at least 6 weeks while in theater. One year later, a check-in with the patient revealed that after returning home, he had been diagnosed with post traumatic stress disorder (PTSD). PTSD symptoms had resolved after 6 months of psychopharmacology and cognitive behavioral therapy. These results indicate that biofeedback may be a useful means of improving sleep in a combat zone, but that such improvements may not necessarily prevent the development of more serious symptoms later. No clear causality can be inferred from a single case, and further study is needed to determine if this finding have wider applicability.     

Effects of lifestyle, personality, symptoms of anxiety and depression, and genetic predisposition on subjective sleep disturbance and sleep pattern.

The effects on sleep pattern ('short-sleep' versus 'long-sleep') and subjective sleep disturbance of genotype, personality, symptoms of anxiety and depression, and lifestyle, were examined using survey data on a clinically unselected sample of adult Australian twin pairs, aged 17-88 years. When the effects of genotype, personality and symptoms were ignored, lifestyle variables appeared to account for roughly 4% of the variance in sleep disturbance, and 9% of the variance in sleep pattern. Significant genetic effects on sleep disturbance and sleep pattern were found, which were only partly explained by the effects of personality and symptoms of anxiety and depression. Much of the association between sleep disturbance and lifestyle appeared to be explained by separate effects of personality and symptoms of anxiety and depression on sleep and lifestyle ('genotype-risk-factor correlation'). There was little evidence for genetically determined differences in sensitivity to the lifestyle variables ('genotype x risk-factor interaction').     

Oleuropein reduces anxiety-like responses by activating of serotonergic and neuropeptide Y (NPY)-ergic systems in a rat model of post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a stress-related mental disorder caused by traumatic experiences. This psychopathological response to traumatic stressors induces anxiety in rats. Oleuropein (OLE), a major compound in olive leaves, reportedly possesses several pharmacological properties, including anti-cancer, anti-diabetic, and anti-atherosclerotic and neuropsychiatric activities. However, the anxiolytic-like effects of OLE and its mechanism of action in PTSD are unclear. The present study used several behavioral tests to examine the effects of OLE on symptoms of anxiety in rats after a single prolonged stress (SPS) exposure by inhibiting the hypothalamic-pituitary-adrenal axis. Male Sprague Dawley rats received OLE (10, 50 and 70?mg/kg, i.p., once daily) for 14 days after SPS exposure. Daily OLE (70?mg/kg) administration significantly increased the number and duration of open arm visits in the elevated plus maze (EPM) test, reduced the anxiety index and grooming behavior in the EPM test, and increased the time spent and number of central zone crossings in the open field test. OLE also blocked the SPS-induced decrease in hippocampal serotonin and neuropeptide Y expression in hippocampus. These findings suggest that OLE has anxiolytic-like effects on behavioral and biochemical symptoms similar to those observed in patients with PTSD.     

Hypodensity of platelet serotonin uptake sites in posttraumatic stress disorder: Associated clinical features

We have previously reported that binding to blood platelets of paroxetine, a selective serotonin (5-HT) reuptake inhibitor which binds to 5-HT uptake sites, is decreased in patients with posttraumatic stress disorder (PTSD). Specifically, we found a lower number of platelet ³H-paroxetine binding sites (B_max) and a lower dissociation constant (K_d) for ³H-paroxetine binding in combat veterans with PTSD compared to normal control subjects. In the current study we assessed the relationship of platelet ³H-paroxetine binding to clinical features in 41 Vietnam combat veterans with SCID-diagnosed PTSD. The results indicated that B_max of platelet ³H-paroxetine binding was negatively correlated with both state and trait anxiety, as well as with depressive and overall PTSD symptoms. However, there was no evidence that platelet ³H-paroxetine binding differed as a function of comorbid psychiatric diagnoses including major depression, other anxiety disorders and substance abuse in these patients.     

Personal experiences of the psoriasis and its relation to the stressful life events

Psoriasis is a disease with a profound impact on the psychological and social aspects of the patient, particularly because of its visibility. Quality of life is impaired and different mental health disorders like depression, anxiety, alcoholism, posttraumatic stress disorder (PTSD) are found among persons suffering from psoriasis. Studies have shown the influence of stressful life events on onset, exacerbation and relapse of psoriasis. Rare studies explored prevalence of psoriasis during war times and relations between psoriasis and war provoked PTSD. Psoriasis is a disease with multiple possible causes and additional caution is necessary among medical professional to recognize all contributing factors. This report describes a case of a person whose first episode of psoriasis appeared six months after engaging in combat activities. He is diagnosed with psoriasis vulgaris, psoriatic arthritis and permanent personality changes after the traumatic experiences caused by war participation. His occupational history is burdened with additional causational factors; work with heavy metals and metal dusts. Cumulative effects of different aetiological factors can contribute to psoriasis with intensive trauma induced stressors serving as a trigger. His medical history indicates cognitive difficulties typical for early dementia which makes this case even more interesting. Research results suggesting common aetiology of psoriasis, autoimmune diseases and neurodegenerative diseases, indicate a need, as in the case of our patient, for multidisciplinary approach to studying aetiology of psoriasis.     

Outcomes and moderators of a preventive school-based mental health intervention for children affected by war in Sri Lanka: a cluster randomized trial

We aimed to examine outcomes, moderators and mediators of a preventive school-based mental health intervention implemented by paraprofessionals in a war-affected setting in northern Sri Lanka. A cluster randomized trial was employed. Subsequent to screening 1,370 children in randomly selected schools, 399 children were assigned to an intervention (n=199) or waitlist control condition (n=200). The intervention consisted of 15 manualized sessions over 5 weeks of cognitive behavioral techniques and creative expressive elements. Assessments took place before, 1 week after, and 3 months after the intervention. Primary outcomes included post-traumatic stress disorder (PTSD), depressive, and anxiety symptoms. No main effects on primary outcomes were identified. A main effect in favor of intervention for conduct problems was observed. This effect was stronger for younger children. Furthermore, we found intervention benefits for specific subgroups. Stronger effects were found for boys with regard to PTSD and anxiety symptoms, and for younger children on pro-social behavior. Moreover, we found stronger intervention effects on PTSD, anxiety, and function impairment for children experiencing lower levels of current war-related stressors. Girls in the intervention condition showed smaller reductions on PTSD symptoms than waitlisted girls. We conclude that preventive school-based psychosocial interventions in volatile areas characterized by ongoing war-related stressors may effectively improve indicators of psychological wellbeing and posttraumatic stress-related symptoms in some children. However, they may undermine natural recovery for others. Further research is necessary to examine how gender, age and current war-related experiences contribute to differential intervention effects.     

Quality of life in families of Croatian veterans 15 years after the war

Exposure to war trauma with its consequences such as post traumatic stress disorder (PTSD) and disability due to combat injuries poses a significant problem for modern Croatian society. However, this is also a public health problem requiring continuous study of effective treatment strategies to achieve an increase in quality of life of most war-affected groups. Aim of this study was to examine the quality of life of population most affected by war - families of Croatian veterans. Present study included 126 female participants, who agreed to complete physical and psychiatric examination organized by the Ministry of Family, War Veterans and Intergenerational Solidarity. Included were participants with status of either wife of war veteran suffering from PTSD, wife who lost her husband in war circumstances or wife of war veteran with physical disabilities resulting from war activities. All three groups were asked to fill out the World Health Organization Quality of Life Questionnaire - short form (WHOQOL-BREF). Results indicate that assumed intensity of secondary trauma is not associated with quality of life. Namely, the highest level of satisfaction was found in wives of the most seriously affected invalids of war (M=3.77; sd=0.741), folowed by the wives of deceased soldiers (M=3.5; sd= 0.697), while the lowest quality of life results were found in wives of veterans suffering from PTSD (M=3.12; sd=0.608). Our results confirm that, nearly 15 years after the war, wives of disabled or killed Croatian soldiers have a (comparatively) satisfactory quality of their everyday lives, compared to the wives of veterans suffering from PTSD.     

Role of maternal 5‐HT1A receptor in programming offspring emotional and physical development

Serotonin_1A receptor (5‐HT_1AR) deficiency has been associated with anxiety and depression and mice with genetic receptor inactivation exhibit heightened anxiety. We have reported that 5‐HT_1AR is not only a genetic but also a maternal ‘environmental’ factor in the development of anxiety in Swiss‐Webster mice. Here, we tested whether the emergence of maternal genotype‐dependent adult anxiety is preceded by early behavioral abnormalities or whether it is manifested following a normal emotional development. Pups born to null or heterozygote mothers had significantly reduced ultrasonic vocalization (USV) between postnatal day (P) 4 and 12, indicating an influence of the maternal genotype. The offspring's own genotype had an effect limited to P4. Furthermore, we observed reduced weight gain in the null offspring of null but not heterozygote mothers, indicating that a complete maternal receptor deficiency compromises physical development of the offspring. Except a short perinatal deficit during the dark period, heterozygote females displayed normal maternal behavior, which, with the early appearance of USV deficit, suggests a role for 5‐HT_1AR during pre‐/perinatal development. Consistent with this notion, adult anxiety in the offspring is determined during the pre‐/perinatal period. In contrast to heterozygote females, null mothers exhibited impaired pup retrieval and nest building that may explain the reduced weight gain of their offspring. Taken together, our data indicate an important role for the maternal 5‐HT_1AR in regulating emotional and physical development of their offspring. Because reduced receptor binding has been reported in depression, including postpartum depression, reduced 5‐HT_1AR function in mothers may influence the emotional development of their offspring.     

An international multicenter association study of the serotonin transporter gene in persistent ADHD

Attention deficit hyperactivity disorder (ADHD) is a common behavioral disorder affecting children and adults. It has been suggested that gene variants related to serotonin neurotransmission are associated with ADHD. We tested the functional promoter polymorphism 5‐HTTLPR and seven single nucleotide polymorphisms in SLC6A4 for association with ADHD in 448 adult ADHD patients and 580 controls from Norway. Replication attempts were performed in a sample of 1454 Caucasian adult ADHD patients and 1302 controls from Germany, Spain, the Netherlands and USA, and a meta‐analysis was performed also including a previously published adult ADHD study. We found an association between ADHD and rs140700 [odds ratio (OR ) = 0.67; P = 0.01] and the short (S) allele of the 5‐HTTLPR (OR = 1.19; P = 0.06) in the Norwegian sample. Analysis of a possible gender effect suggested that the association might be restricted to females (rs140700: OR = 0.45; P = 0.00084). However, the meta‐analysis of 1894 cases and 1878 controls could not confirm the association for rs140700 [OR = 0.85, 95% confidence interval (CI) = 0.67–1.09; P = 0.20]. For 5‐HTTLPR, five of six samples showed a slight overrepresentation of the S allele in patients, but meta‐analysis refuted a strong effect (OR = 1.10, 95% CI = 1.00–1.21; P = 0.06). Neither marker showed any evidence of differential effects for ADHD subtype, gender or symptoms of depression/anxiety. In conclusion, our results do not support a major role for SLC6A4 common variants in persistent ADHD, although a modest effect of the 5‐HTTLPR and a role for rare variants cannot be excluded.     

Effectiveness and specificity of a classroom-based group intervention in children and adolescents exposed to war in Lebanon

The purpose of this study was to examine the effectiveness and specificity of a classroom-based psychosocial intervention after war. All students (n=2500) of six villages in Southern Lebanon designated as most heavily exposed to war received a classroom-based intervention delivered by teachers, consisting of cognitive-behavioural and stress inoculation training strategies. A random sample of treated students (n=101) and a matched control group (n=93) were assessed one month post-war and one year later. Mental disorders and psychosocial stressors were assessed using the Diagnostic Interview for Children and Adolescents - Revised with children and parents. War exposure was measured using the War Events Questionnaire. The prevalence of major depressive disorder (MDD), separation anxiety disorder (SAD) and post-traumatic stress disorder (PTSD) was examined pre-war, one month post-war (pre-intervention), and one year post-war. Specificity of treatment was determined by rating teachers’ therapy diaries. The rates of disorders peaked one month post-war and decreased over one year. There was no significant effect of the intervention on the rates of MDD, SAD or PTSD. Post-war MDD, SAD and PTSD were associated with pre-war SAD and PTSD, family violence parameters, financial problems and witnessing war events. These findings have significant policy and public health implications, given current practices of delivering universal interventions immediately post-war.     

Effects of Pharmacotherapy on Combat-Related PTSD,Anxiety, and Depression: A Systematic Review and Meta-Regression Analysis

ObjectivesTo estimate the effect of pharmacotherapy on PTSD, anxiety, and depression among combat veterans; to determine whether the effects varied according to patient and intervention characteristics; and to examine differential effects of pharmacotherapy on outcomes.ResultsPharmacotherapy significantly reduced (Δ, 95%CI) PTSD (0.38, 0.23-0.52), anxiety (0.42, 0.30-0.54), and depressive symptoms (0.52, 0.35-0.70). The effects of SSRIs and tricyclic antidepressants on PTSD were greater than other medications independent of treatment duration. The effect of SSRIs and tricyclic antidepressants were greater than other medications up to 5.2 and 13.6 weeks for anxiety and depression, respectively. The magnitude of the effect of pharmacotherapy on concurrently-measured PTSD, anxiety, and depression did not significantly differ.ConclusionsPharmacotherapy reduced PTSD, anxiety, and depressive symptoms in combat veterans. The effects of SSRIs and tricyclic antidepressants were greater for PTSD and occurred quicker for anxiety and depression than other medications.     

Age-developmental stage and severity of trauma related symptoms, anxiety and depressive symptoms in participants who lost their fathers during the war in Croatia

Children of different ages will experience a traumatic event in a different ways. The most important in the generalization of research findings is recognizing that children of different ages think differently, act differently and have different emotional functioning. Experiences that are extremely traumatic to an adult may be perceived by a young child as something that is not so frightening. The fear that the child feels will more frequently be a reflection of that of the adult rather than generated by the child's own perception of the event. So, the individual experience of the trauma is age dependent. Our study focused on children who lost their fathers in conditions of war The aim was to explore the association between age-developmental stages and the severity of trauma related symptoms, anxiety and depressive symptoms in participants who lost their fathers during the war. The study included 103 people who lost their fathers during the war in Croatia, who came to the physical and psychiatric examination organized by the Ministry of Family, War Veterans and Intergenerational Solidarity. The sample was consisted of the participants who were children, or not born yet, at the time when they lost their fathers during the war in Croatia. At the time of interview, the participants were aged between 15 and 35 years old. Data was collected using a structured clinical interview which also included socio-demographic data. Data about former and current psychiatric symptoms were collected using the following instruments: Clinician- Administrated PTSD Scale (CAPS), Hamilton anxiety scale (HAMA), Hamilton depression scale (HAMD). Results showed that there was significant correlation between age and results on used scales. The participants who lost their fathers at a very young age or even before they were born showed less trauma symptoms (r=0.249; p < 0.05) less anxiety (r=0.374; p < 0.01) and depressive (r=0.384; p<0.01) symptoms than participants who lost their fathers at an older age. The study confirmed that the individual experience of the trauma of losing a father in war circumstances is associated with age.
