Mate Mihanović,1,2 Branka Restek-Petrović,1,2 Anamarija Bogović,1 Ena Ivezić,1 Davor Bodor,1 Ivan Požgain3 1Psychiatric Hospital “Sveti Ivan”, Zagreb, 2Faculty of Medicine Osijek, Josip Juraj Strossmayer University of Osijek, 3Department of Psychiatry, University Hospital Center Osijek, Osijek, Croatia Background: The Sveti Ivan Psychiatric Hospital in Zagreb, Croatia, offers foster home care treatment that includes pharmacotherapy, group psychodynamic psychotherapy, family therapy, and work and occupational therapy. The aim of this study is to compare the health-related quality of life of patients with schizophrenia treated in foster home care with that of patients in standard outpatient treatment. Methods: The sample consisted of 44 patients with schizophrenia who, upon discharge from the hospital, were included in foster home care treatment and a comparative group of 50 patients who returned to their families and continued receiving outpatient treatment. All patients completed the Short Form 36 Health Survey Questionnaire on the day they completed hospital treatment, 6 months later, and 1 year after they participated in the study. The research also included data on the number of hospitalizations for both groups of patients. Results: Though directly upon discharge from the hospital, patients who entered foster home care treatment assessed their health-related quality of life as poorer than patients who returned to their families, their assessments significantly improved over time. After 6 months of treatment, these patients even achieved better results in several dimensions than did patients in the outpatient program, and they also had fewer hospitalizations. These effects remained the same at the follow-up 1 year after the inclusion in the study. Conclusion: Notwithstanding the limitations of this study, it can be concluded that treatment in foster home care is associated with an improvement in the quality of life of patients with schizophrenia, but the same was not observed for the patients in standard outpatient treatment. We hope that these findings will contribute to an improved understanding of the influence of psychosocial factors on the functioning of patients and the development of more effective therapeutic methods aimed at improving the patients’ quality of life.

Introduction: Affective disorders are among the most common mental health problems in women of reproductive age. A life-changing condition, such as pregnancy, may trigger or intensify symptoms of affective disorders, rather than pregnancy being a protective factor for the development of the disorder, as previously thought. Previous research indicates that 18% of women suffer from perinatal depression. One in 7-10 pregnant women and 1 in 5-8 midwives develops a depressive disorder, which is more than half a million women a year. Untreated perinatal depression has significant repercussions for both mother and child. Given that there are no controlled randomized studies during pregnancy, and the results of previous research on the harmfulness of the use of psychotropic drugs are contradictory, we need to nurture an individualized and integrative approach to the use of psychotropic drugs in pregnant women and in the postpartum period. The goal of this lecture is to point out the necessity of treating perinatal depressive disorder with an emphasis on the need to work on dilemmas and selected sources of information by pregnant women themselves, as well as health professionals. In the end, I must emphasize the importance of choosing an adequate psychopharmaceutical in that sensitive period for a woman, nurturing an individual approach as well as the latest knowledge. Objectives: The aim of this research is to examine the attitudes of psychiatrists, GP doctors, gynecologists and pregnant women about prescribing and taking pharmacotherapy during pregnancy. Methods: The research will be conducted at the psychiatry clinic, the gynecology clinic and in health centers through semi-structured questionnaires, which will be filled out by psychiatrists, gynecologists, doctors and pregnant women. Results: Preliminary results (given that the research is still ongoing) indicate that most psychiatrists avoid prescribing drugs during pregnancy, and if they decide to do so, then diazepam is prescribed. The views of gynecologists, family medicine doctors and pregnant women are still pending. Conclusions: This lecture aims to point out the factors contributing to the fear of prescribing psychotropic drugs perinatally, based on our own research, which included psychiatrists, gynecologists, family medicine doctors, and pregnant women.

Background: Understanding causes and consequences of untreated psychosis is important since the duration of psychosis prior to the treatment initiation is a potentially modifiable prognostic factor, and comprehending its impact on outcome may enhance therapeutic strategies., Subjects and Methods: This cross-sectional study was performed on a consecutive sample of 105 participants, 47 first episode participants and 58 with multiple episodes. Primary outcome was the duration of untreated psychosis (DUP). We observed three independent variables: childhood trauma measured by Childhood Trauma Questionnaire, psychotic symptoms measured by Positive and Negative Syndrome Scale (PANSS) and personality dimensions measured by the Inventory of Personality Organization (IPO) (primitive defences, identity diffusion and reality testing). All outcomes were observed among total sample and subgroups of first and multiple episode participants., Results: Median DUP in total sample was 60.0 (IQR 14.5-285) days. In the subgroup of multiple episode participants, an association between multiple childhood trauma and shorter DUP was found, while no association between DUP and the existence of any specific trauma was found in neither subgroup, or in total sample. With regards to personality dimensions, in the first episode subgroup, significant positive correlations between DUP and primitive defences and reality testing subscales were found, while no correlations in total sample, nor in multiple episode subgroup were observed. Positive symptoms and general psychopathology correlated positively with DUP in total sample, and in first episode subgroup, while in multiple episodes subgroup only a positive correlation with positive symptoms was found. Total PANSS score positively correlated with the DUP only in the first episode subgroup., Conclusions: DUP was not associated with specific type of childhood trauma. First episode participants with longer DUP had predominant primitive defences and severely decreased ability to test reality, while there were no correlations between personality dimensions and DUP in multiple episode subgroup.

Aim: The association between various physical illnesses and schizophrenia spectrum disorder (SSD) is well-established. However, the role of gender remains unclear. The present study explored the gender-based differences in the prevalence and early onset of chronic physical multimorbidities (CPM) in patients with SSD and the general population (GEP)., Methods: We recruited 329 SSD patients and 837 GEP controls in this nested cross-sectional study. The primary outcome was the prevalence of the chronic physical multimorbidities, especially in the youngest age group (<35 years)., Results: Women with SSD had more than double the odds for having CPM than men (OR = 2.47; 95% CI 1.35-4.50), while the gender-related burden of chronic diseases in controls was nearly the same (OR = 0.89; 95% CI 0.65-1.22). Furthermore, the prevalence of chronic disease in younger women patients was significantly higher than in controls (P = .002), while younger men did not seem to experience this increased comorbidity burden., Conclusions: This study suggests that women with SSD are at increased physical comorbidity risk compared to men, particularly early in the course of psychiatric illness. Tailored and individualized treatment plans must consider this, aiming to deliver holistic care and effective treatment outcomes., (© 2019 John Wiley & Sons Australia, Ltd.)

Repetitive transcranial magnetic stimulation (rTMS) is an evidence-based treatment option for major depressive disorder (MDD). However, comparisons of efficacy between the two FDA-approved protocols of rTMS modalities are lacking. The aim of this industry-independent, randomized-controlled, single-blind trial was to evaluate clinical outcome of the two FDA-approved rTMS protocols delivered by H1-coil and the figure-8-coil, in MDD patients. A total of 228 MDD patients were randomized to 20 sessions of H1-coil or 8-coil as an adjunct to standard-of-care pharmacotherapy, or standard-of-care pharmacotherapy alone. Baseline MDD symptom severity was almost the same in the three groups. Hamilton depression rating scale (HAM-D17) mean score was 17 (5.3) in H1-coil, 17 (5.4) in 8-coil, and 19 (6.1) in control group. The primary outcome was the proportion of patients achieving remission defined as HAM-D17 score ≤7 at end-of-treatment at week-4. In the intention-to-treat analysis odds ratio for remission was 1.74 (CI95% 0.79-3.83) in H1-coil compared to the 8-coil group. The difference between two rTMS protocols was not significant. Remission rate was significantly greater in both HF-rTMS groups compared to the control: 60% (CI95% 48-71%), 43% (CI95% 31-55%) and 11% (CI95% 5-20%) respectively. The response was significantly better in H1-coil, than in 8-coil group OR = 2.33; CI95% 1.04-5.21 (P = 0.040). The HAM-D17 was lowered by 59% in the H1-coil, 41% in the 8-coil (P = 0.048), and 17% in the control group (P < 0.001 vs H1-coil; P = 0.003 vs 8-coil). Safety, tolerability, and the changes in quality of life were comparable. We confirmed the safety and efficacy of both FDA-approved protocols as adjunctive treatments of MDD. Better response rate and greater reduction of depression severity were observed in the H1-coil group, but without a significant difference in the remission rate between the two rTMS modalities.

Background: The Day hospital for early intervention is a time-limited structured therapeutic program based on different psychotherapy and socio-therapy techniques. The aim of this study was to examine the outcomes of the Day hospital treatment for early intervention on self-esteem, and quality of life, and to determine which patients benefit the most from the program., Subjects and Methods: The study was conducted on 124 patients with an early phase of psychosis who were treated at the Day hospital. They filled out Rosenberg Self-Esteem Scale, and WHOQOL-BREF upon the admission and again after three months of the treatment. Interaction effects were examined between their sociodemographic characteristics (gender, age, employment status), clinical features (first episode of psychosis or longer duration of illness), and results on applied questionnaires., Results: After three months of the treatment, patients evaluated their self-esteem, overall quality of life and satisfaction with different QoL domains (physical and psychological health, environment) as significantly improved. Younger patients had greater increase in estimated self-esteem compared to older patients. No other significant interactions were found., Conclusion: Notwithstanding the limitations of this study, we may conclude that the findings are encouraging and may assist with development of more effective therapeutic approaches.

Background: Hyperprolactinemia is associated with side effect of antipsychotics in people suffering from psychotic disorders. However, increased prolactin levels (mlU/L) were found in patients suffering from the first psychotic episode who were not receiving antipsychotic therapy. The assumption of this study is that the abnormality in the level of prolactin is associated with the effect and influence of the disease, not the therapy that is carried out., Subjects and Methods: Study involved 54 female patients hospitalized in Psychiatric hospital "Sveti Ivan", whose average age was 33.9 years. All patients had been diagnosed with a psychotic disorder (according to MKB-10, F20-F29). 18 patients had their first psychotic episode, while 36 patients had relapses of psychotic disorder. The methods used were: PANSS scale and measurement of prolactin concentration (Immunoanalyzer ACCESS 2, CLIA method). Arithmetic mean, standard deviations, correlation coefficient, Mann Whitney U test and the chi-squared test were used., Results: 75.5% of patients had prolactin values above the reference values (min 121, max 4192 ml/L). In a sample of patients with first psychotic episode, 77.8% had elevated prolactin levels, while among re-hospitalized patients, elevated levels had 74.2%. Statistically significant results were obtained: patients with higher pronounced symptoms had higher prolactin values, especially particles on PANSS: P1 (delusions), N4 (Apathy), G15 (preoccupation) and G16 (active avoidance)., Conclusion: Elevated prolactin in patients has been demonstrated regardless of antipsychotic therapy, therefore the question of etiology of hyperprolactinemia in psychotic disorders is questionable. The association of hyperprolactinemia with the severity of the clinical picture has also been demonstrated, higher prolactin values indicating a stronger clinical picture, which calls into question the protective role of prolactin in psychotic disorders.

Background: Growing body of evidence has opened new opportunities to enhance treatment outcomes during early-phase psychosis (EPP). The objective of this study was to evaluate the effect of the Centre for integrative psychiatry (CIP) multimodal Early Intervention Services (EIS) on time to relapse in the patients with early-phase psychosis (EPP) during 12 and 24 month period., Subjects and Methods: We performed a retrospective cohort study on the sample of 454 EPP patients (duration of the diagnosed disorder ≤5 years) admitted to Psychiatric Hospital "Sveti Ivan", Zagreb Croatia, from January 2, 2015, to December 5, 2018, for the acute treatment of EPP. The end of follow up was March 5, 2019. The primary outcome was the time to rehospitalization because of relapse during the 12 months from the hospital discharge. Independent variable was the EIS., Results: We analyzed 454 EPP patients, 260 in EIS group and 194 in no EIS group. After the adjustment for twenty possible confounding factors using the Cox proportional hazard regression, patients who received EIS had significantly and clinically relevantly lower hazard for rehospitalization because of relapse during the first 12 months (HR=0.39; CI 95% 0.21-0.61; p<0.001), and during the first 24 months from the hospital discharge (HR=0.56; CI 95% 0.39-0.80; p=0.003; sequential Holm-Bonferroni corrected p corr =0.004)., Conclusions: Our study indicated efficacy of the CIP multimodal EIS in patients with EPP demonstrated through the time to the hospital readmission because of relapse during the 12 and 24 months from the hospital discharge. These results strongly support the need for implementation of multimodal EIS in all patients with EPP.

Background: The prevalence of ABO alleles is different in different populations, and many studies have shown a correlation between the occurrences of some diseases and different genotypes of ABO blood groups. The aim of this study was to determine whether there is a significant association between psychiatric syndromes and ABO blood groups., Materials and Methods: This case-control study involved 156 psychiatric patients and 303 healthy, unrelated, voluntary blood donors. Genomic DNA was isolated from blood on a QIAcube device using a QIAamp DNA Blood mini QIAcube kit. ABO genotyping on five basic ABO alleles was performed using allele-specific polymerase chain reaction analysis., Results: Compared with healthy subjects, a significantly higher proportion of psychiatric patients had AB blood group (χ 2 =9.359, df=3, p=0.025) and, accordingly, a significantly higher incidence of A1B genotype (χ 2 =8.226, df=3, p=0.042). The odds ratio showed that psychiatric disorders occur almost three times more frequently in carriers of AB group compared to other blood groups. However, no statistically significant difference was found in the distribution of ABO blood groups among patients with different psychiatric diagnoses. Likewise, no correlations were found between ABO blood groups and other characteristics of the psychiatric patients (sex, psychiatric heredity, somatic comorbidity, suicidality)., Conclusions: The results of this study support the hypothesis of an association between psychiatric disorders and ABO blood groups. The probability is that psychiatric disorders will occur almost three times more frequently in carriers of AB group compared to other ABO blood groups in the Croatian population.

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique with few side effects that has been reported to be effective in the treatment of major depressive disorder (MDD). At present, no randomized controlled trials (RCT) have compared the efficacy and safety of rTMS delivered by the figure-8-coil and the H1-coil. We describe an industry-independent, randomized, controlled, single-blinded, single-center study protocol assessing the differences in efficacy and safety of rTMS for patients diagnosed with MDD with the H1-coil and figure-8-coil as an add-on to stable pharmacotherapy or pharmacotherapy alone. Stimulation protocols follow those that led to the FDA clearance of these treatments for MDD. The sample of 76 patents in each of the three groups will be enrolled and assessed with clinical and neuropsychological tests. The primary outcome is remission rate defined as Hamilton depression rating scale (HAM-D17) score ≤7 at the end of week-4. This clinical trial will address the efficacy and safety of rTMS modalities for MDD. The evaluation of biological markers will also help to elucidate the pathophysiology of MDD and the mechanisms of action of rTMS.

Background: Psychiatric hospital "Sveti Ivan" in Zagreb, Croatia, offers an outpatient Early intervention programme for patients with psychotic disorders (RIPEPP), consisting of psychoeducational workshops and group psychodynamic psychotherapy. The aim of this study was to describe sociodemographic and baseline characteristics of the participants, in order to provide better understanding of this population, and to assist with the development of more effective therapeutic approaches., Subjects and Methods: Since 2008, a total of 245 patients with first episodes of psychosis and their family members participated in the programme. They filled out several questionnaires within the framework of the programme evaluation, but for the purposes of this study, only data collected on sociodemographic questionnaire and the Health of the Nation Outcome Scales (HoNOS) are presented., Results: Majority of the participants were male (66%), at the average age of 28 (SD=6.6), living with their parents (73.5%). Most of them finished secondary school (45.7%) but almost a quarter of the sample (23.7%) is currently studying at university. The average duration of untreated period was 101.60 days, with a median of 30 days. According to results of HONOS questionnaire, upon entry into the programme, the patients most often listed cognitive functioning (attention, concentration, memory) and professional issues (performance of work tasks and activities tied to work) as the most problematic areas., Conclusion: The findings of this study provide more detailed description of the beneficiaries of the RIPEPP programme, which can contribute to forming future programmes for the prevention of psychotic disorders.

Background: The aim of this study was to examine the day hospital treatment outcome on severity of clinical manifestations, general neuroticism and coping mechanisms in patients suffering from chronic combat-related PTSD., Subjects and Methods: The sample consisted of 38 consecutive patients admitted to the Day Hospital treatment of PTSD during one year observation period. The average age of the sample was 46.03 years. The patients completed 3 self-report measures upon admission to the hospital and upon discharge: The Mississippi scale for combat-related PTSD (M-PTSD), The Crown-Crisp experiential index (CCEI), and The COPE inventory., Results: There was no significant change in the severity of clinical manifestations of PTSD, general neuroticism and coping mechanisms among the whole sample. However, compared to married participants and participants with children, single participants and those without children reported higher levels of anxiety when admitted to the hospital, but lower levels at discharge. In addition, patients without children reduced their avoidance behavior during the treatment., Conclusion: This preliminary study showed that single patients and those without children may benefit more from the day hospital treatment program. Our findings emphasize the importance of social support in the recovery process of severely traumatized persons, and may assist with the development of more effective therapeutic approaches.

Background: The aim of this study was to determine the size of personal space among war veterans with PTSD, compared to healthy individuals, and to examine its associations with some sociodemographic and clinical characteristics., Subjects and Methods: Participants were 83 male war veterans with chronic PTSD and 85 healthy male employees of the medical institutions. Preferred interpersonal distances were assessed by using a stop-distance technique, where male and female research assistants approached the participants from four directions (front, behind, left, right). The patients filled out The Mississippi Scale for Combat-Related Posttraumatic Stress Disorder (M-PTSD)., Results: War veterans with PTSD preferred significantly larger interpersonal distances compared to healthy participants. Larger personal space size was preferred by those who had children, and the largest preferred distances were observed for the approaches from behind. Both samples preferred larger distances when approached by a male person., Conclusion: The findings of this study contribute to increased understanding of the personal space in patients with PTSD, and may be implemented into prevention of aggressive behavior during psychiatric treatment, and into development of more effective therapeutic strategies.

This study aimed to investigate the development of the group process through group climate parameter dynamics during long-term psychodynamic group psychotherapy for 30 outpatients with psychosis. The group process in four groups was monitored using MacKenzie's Group Climate Questionnaire-Short Form (GCQ-S) that was completed by the therapist after each session over the two-year period. The trends of engagement, avoidance and conflict parameters differed between groups, and no clear indicators of the development phases were found. The results suggested that these groups remained in the first developmental phase during the observation period, and highlighted the characteristics of resistance and difficulties in establishing social relations in patients with psychosis.

Background: This study aimed to examine the relationship between some personality characteristics of patients diagnosed with psychotic disorders and the quality of their engagement in psychodynamic group psychotherapy. Given that previous research has shown that self-stigma is significantly negatively associated with the engagement of patients, the measure of self-stigma was used as a correlate of patients' motivation to participate in group psychotherapy., Subjects and Methods: A total of 48 outpatients (52.1% women; mean age 35.30 years) attending group psychodynamic psychotherapy completed The Inventory of Personality Organization, The Pathological Narcissism Inventory, The Measure of Parental Style, The Relationship Questionnaire, and The Internalized Stigma of Mental Illness scale., Results: The findings showed that patients with higher levels of self-stigma have unhealthy attachments styles, perceived their mothers' parental style as indifferent and achieved greater scores on narcissistic vulnerability scale. They are also are prone to primitive psychological defences, have poorly integrated identity, and achieved lower scores on reality testing dimension., Conclusion: Taking into account the limitations of this study, these findings may contribute to improved understanding of the quality of participation and engagement of psychotic patients in group psychotherapy, and may help to develop more effective therapeutic approaches.

Background: The "Sveti Ivan" psychiatric hospital in Zagreb, Croatia, offers an outpatient Early Intervention Program for psychotic patients. This program consists of psycho-educational workshops and group psychodynamic psychotherapy. Two important objectives of the program are improving and maintaining adequate cognitive functioning., Aims: The current study examined changes in aspects of cognitive functioning in young patients with schizophrenia after 18 months and after 3 years of psychodynamic group psychotherapy., Methods: The study included 28 patients who attended the Early Intervention Program for young patients with psychotic disorders; 10 patients had completed only the psycho-educational part of the program (comparative group), and 18 patients continued with group psychodynamic psychotherapy (experimental group). All patients completed the Revised Beta Examination., Results: We observed a trend in the experimental group to achieve higher scores than the comparative group. The results for both groups tended to increase with time, and this increase was greater in the experimental group., Conclusions: While acknowledging the limitations of this preliminary study, we conclude that participating in psychodynamic group psychotherapy is related to increases in the cognitive functioning of patients with schizophrenia, and our results provide a sound basis for future research.

Background: In recent years, social functioning of patients has increasingly been used as a criterion for assessing therapeutic efficacy of the group psychotherapy. The purpose of this preliminary study was to examine whether social functioning of patients with diagnosed psychotic disorders changes during their participation in psychodynamic group psychotherapy., Subject and Methods: The sample consisted of 30 patients involved in the psychodynamic group psychotherapy (PGP), and a comparative group of 30 patients treated only with antipsychotic medication therapy (treatment as usual; TAU). After two years of therapy, the instruments designed for this study (self-assessment and therapist-assessment questionnaire) were applied to examine changes in patient communication in their interpersonal relations, romantic and working functioning, and overall social functioning. The research also included data as to whom patients turned to for help, and the number of hospitalisations in the observed period., Results: The majority of patients from both groups assessed their social functioning as improved, with significant differences found only in the area of romantic relations: more patients in the TAU group assessed their functioning as worsened. Nevertheless, a significantly higher number of patients in the PGP group were assessed by their therapists to have improved social functioning in all dimensions, except in the area of romantic relations, where there was no statistically significant difference between the groups. In comparison with the TAU group, twice as many patients in the PGP group turned to their psychiatrist for help and had four times fewer hospitalisations., Conclusion: Considering the limitations of this preliminary study, it can be concluded that the findings are promising, although further research is required to determine whether a psychodynamic approach to group psychotherapy truly leads to improved social functioning of patients with psychotic disorders.

Objective: The aim of this study was to examine the relationships between pathological narcissism (narcissistic grandiosity and narcissistic vulnerability), dysfunctional attitudes (perfectionism and dependency on other people), and depressive symptoms in psychiatric outpatients., Method: A sample of 234 adult psychiatric outpatients (57.3% male; mean age 44.39 years) completed the Pathological Narcissism Inventory, the Dysfunctional Attitudes Scale-Form A, and the Depression, Anxiety, Stress Scales-21., Results: Narcissistic vulnerability exhibited unique positive correlations with depressive symptoms, whereas narcissistic grandiosity showed substantially weaker correlations with depressive symptoms. Perfectionism partially mediated the relationship between narcissistic vulnerability and depressive symptoms. The mediating role of dependency was not confirmed., Conclusions: Among adult psychiatric outpatients, narcissistic vulnerability is more strongly related to depressive symptoms than narcissistic grandiosity, and dysfunctional perfectionism represents one of the underlying mechanisms of this relationship. The implications of these findings are discussed in relation to the Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria and the treatment of pathological narcissism., (© 2013 Wiley Periodicals, Inc.)

The aim of this study was to examine the factorial and diagnostic validity of the Beck Depression Inventory-Second Edition (BDI-II) in Croatian primary health care. Data were collected using a medical outpatient sample (N = 314). Reliability measured by internal consistency proved to be high. While the Velicer MAP Test showed that extraction of only one factor is satisfactory, confirmatory factor analysis indicated the best fit for a 3-factor structure model consisting of cognitive, affective and somatic dimensions. Receiver operating characteristics (ROC) analysis demonstrated the BDI-II to have a satisfactory diagnostic validity in differentiating between healthy and depressed individuals in this setting. The area under the curve (AUC), sensitivity and specificity were high with an optimal cut-off score of 15/16. The implications of these findings are discussed regarding the use of the BDI-II as a screening instrument in primary health care settings.

Background: A number of studies have shown that although exposure to potentially traumatic events is common, development of PTSD is relatively rare, which is one of the reasons PTSD still remains a controversial psychiatric entity. The aim of this article was to provide an overview of the research on the role of personality traits in the vulnerability, resilience, posttraumatic growth and expressions associated with PTSD. Personality based approach represents a dimensional aspect of the transdisciplinary integrative model of PTSD., Methods: We conducted a systematic search on PubMed, PsycINFO, and Academic Search Complete from 1980 (the year PTSD was first included in the DSM) and 2012 (the year the literature search was performed). Manual examination of secondary sources such as the reference sections of selected articles and book chapters were also conducted., Results: Most of the reviewed studies dealing with personality traits as vulnerability and protective factors for PTSD examined the relationship between basic personality dimensions and severity of symptoms of PTSD. These studies have applied three types of methodological designs: cross-sectional, post-trauma and pre-trauma longitudinal studies, with latter being the least common option., Conclusion: Finding that appears relatively consistent is that PTSD is positively related to negative emotionality, neuroticism, harm avoidance, novelty-seeking and self-transcendence, as well as to trait hostility/anger and trait anxiety. On the other hand, PTSD symptoms are negatively associated with extraversion, conscientiousness, self-directedness, the combination of high positive and low negative emotionality, as well as with hardiness and optimism, while posttraumatic growth shows inverse relation to most of these traits. Furthermore, a number of studies have confirmed the existence of three distinct personality-based subtypes of PTSD: internalizing, externalizing and low pathology PTSD. These findings may help in further uncovering etiological mechanisms and in building new strategies for prevention, identification and reduction of health risks among this trauma population, as well as facilitating potential posttraumatic growth. However, focusing on just a single dimensional perspective will unable us to generate comprehensive knowledge of the etiology, course and treatment of PTSD.
