This study aims to provide evidence concerning the effects of experiencing multiple forms of victimization (poly-victimization) on self-esteem and post-traumatic stress symptoms in Spanish adolescents. A total of 722 adolescents were recruited from seven secondary schools in Catalonia, Spain. The Rosenberg Self-Esteem Scale, the Youth Self Report and the Juvenile Victimization Questionnaire were employed to assess self-esteem, post-traumatic stress symptoms and victimization, respectively. Participants were divided into three groups (non-victim, victim and poly-victim groups) according to the total number of different kinds of victimization experienced. Results showed that 88.4 % of adolescents had been exposed to at least one kind of victimization. Poly-victimization was associated with a higher number of post-traumatic stress symptoms in both boys and girls. Also, self-liking was significantly lower in the poly-victim group, whereas self-competence was equivalent across the three victimization groups. Girls were approximately twice as likely to report child maltreatment (OR = 1.92) and sexual victimization (OR = 2.41) as boys. In conclusion, the present study adds evidence on the importance of taking account of the full burden of victimizations suffered when studying victimization correlates. Also, it highlights the importance of prevention policies to focus particularly on preserving adolescents' sense of social worth.

This study aims to provide data regarding the association between reported degree of victimization and suicidal phenomena, with special emphasis on gender differences. There were 923 adolescents recruited from eight secondary schools in Catalonia, Spain. The Youth Self-Report (YSR) and the Juvenile Victimization Questionnaire (JVQ) were used to assess suicidal phenomena and victimization, respectively. Participants were divided into three groups (nonvictim, victim, and polyvictim groups) according to the total number of different kinds of victimization reported. Results showed that the polyvictim group reported significantly more suicidal phenomena than did the victim and nonvictim groups in both boys and girls. Furthermore, although no gender differences in reported suicidal phenomena were found in the nonvictim group, girls reported significantly more suicidal phenomena in both the victim and the polyvictim groups. In conclusion, the results suggest that victimization may play an important role in generating gender differences with respect to reported suicidal phenomena. In addition, this study highlights the importance of taking into account the whole range of victimizations suffered by adolescents when seeking to design suicide prevention and intervention policies.

BackgroundThe representation of low- and middle-income countries (LMIC) in traumatic stress research is important to establish a global evidence base, build research capacity, and reduce the burden of unmet mental health needs around the world. Reviews of the traumatic stress literature up to 2002 showed trends toward globalization although LMIC were only marginally represented compared to high-income countries (HIC).ObjectiveTo examine the global nature of current traumatic stress research. In particular, we were interested in the extent to which traumatic stress research is: (1) conducted in LMIC, (2) conducted by LMIC researchers, and (3) accessible to them.MethodUsing the databases PubMed, PsychInfo, and PILOTS, we systematically searched for peer-reviewed articles on traumatic stress published in any language in the year 2012. Out of the 3,123 unique papers identified, we coded a random sample (N=1,000) for study, author, article, and journal characteristics.ResultsAlthough our sample involved research in 56 different countries, most papers (87%) involved research in HIC, with 51% of all papers describing studies in the United States. In 88% of the papers, the author team was affiliated with HIC only. Less than 5% of all author teams involved collaborations between HIC and LMIC researchers. Moreover, 45% of the articles on LMIC studies published by a HIC corresponding author did not involve any LMIC co-authors. LMIC researchers appeared to publish empirical studies in lower impact journals. Of the 1,000 articles in our sample, 32% were open access and 10% were made available via different means; over half of the papers were not accessible without subscription.ConclusionsTraumatic stress research is increasingly global but still strongly dominated by HIC. Important opportunities to build capacity in LMIC appear to be missed. Implications toward more international traumatic stress research are discussed.

The current study examines the relationship between the total kinds of victimization (TKV) experienced, self-esteem, and internalizing symptoms (IS) and externalizing symptoms (ES). It also explores the mediator and/or moderator role of two self-esteem facets: self-liking (SL) and self-competence (SC). The sample comprised 736 adolescents recruited from eight secondary schools in Catalonia, Spain. The Rosenberg Self-Esteem Scale, the Youth Self Report, and the Juvenile Victimization Questionnaire were used to assess self-esteem facets (SL and SC), psychological distress (IS and ES), and the TKV suffered. This article has several innovative features. On one hand, it considers that self-esteem is comprised of two different but related factors: SL and SC. On the other hand, it is the first study to provide evidence for the mediator/moderator role of SL and SC between victimization and psychological symptoms, taking account of the TKV experienced. Results suggest that SL is more relevant to mental health than SC. A low sense of being a worthy social being (SL) is more closely related to both victimization and poor mental health than a low sense of personal efficacy (SC). Moreover, SL seems to partially mediate the relationship between TKV and both IS and ES, whereas SC only acts as a partial mediator for the TKV-IS relationship in girls. At the same time, SL acts as a partial moderator of the TKV-IS relationship in boys. These findings support the importance of self-esteem in buffering the impact of victimization on mental health and may indicate that proper prevention and treatment policies should focus on adolescents' sense of being a good person, according to their own criteria of worth.

The main objective of this paper is to study the relationship between different areas of victimization (e.g., sexual victimization) and psychological symptoms taking into account the full range of victimizations adolescents suffer. The final aim is to contribute further evidence regarding the bias that those studies which focus on just one area of victimization may be introducing into our psychological knowledge. A total of 923 adolescents (62.4% girls) between 14 and 18 years old were recruited from seven secondary schools in Catalonia, Spain. The Youth Self-report and the Juvenile Victimization Questionnaire were employed to assess psychological problems (internalizing and externalizing symptoms) and victimization, respectively. The large majority of adolescents reported having experienced more than one area of victimization. However, Conventional Crime area was the one that was more reported in isolation. Overall, the explicative power of a particular area of victimization was greatly reduced or even lost its significance when the other areas were taken into account. However, some areas remained significant and were different by gender. Clinicians and researchers should take into account the whole range of victimizations adolescents suffer when intending to understand the psychological aftermaths of victimization. Some areas of victimization appear to be more important at explaining particular psychological symptoms, those being Peer and Sibling Victimization in the case of boys, and both Conventional Crime and Internet Victimization in the case of girls.
