RESUMO

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.

RESUMO

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.

RESUMO

The present study aimed to identify the best structure of the Adolescent Coping Orientation for Problem Experiences when applied to Spanish adolescents. A confirmatory factor analysis of five previous factor structures was conducted. As the data did not fit previous factor models, two exploratory factor analyses (first- and second-order) were carried out to identify the structure for Spanish adolescents and to analyse its criterion validity in relation to mental health, which was assessed by means of the Youth Self-Report. A first-wave sample of 1,152 secondary education pupils (645 boys, 56%; 507 girls, 44%; M age = 14.4 yr., SD = 1.4) was involved in the confirmatory and exploratory factor analyses. A second-wave sample of = 374 secondary education pupils (188 boys, 50.5%; 186 girls, 49.5%; M age = 15.4 yr., SD = 1.1) was used to assess criterion validity. The results yielded eight first-order factors with Cronbach's alpha ranging from .63 to .79, and two second-order factors that replicated the Approach and Avoidance focus of coping. The paper discusses both the content of the extracted factors and mental health issues.

RESUMO

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.

RESUMO

Transient liquid assisted growth (TLAG) is an ultrafast non-equilibrium growth process mainly governed by kinetic parameters, which are only accessible through fast in situ characterizations. In situ synchrotron X-ray diffraction (XRD) analysis and in situ electrical resistivity measurements are used to derive kinetic diagrams of YBa2 Cu3 O7- x (YBCO) superconducting films prepared via TLAG and to reveal the unique peculiarities of the process. In particular, diagrams for the phase evolution and the YBCO growth rates have been built for the two TLAG routes. It is shown that TLAG transient liquids can be obtained upon the melting of two barium cuprate phases (and not just one), differentiated by their copper oxidation state. This knowledge serves as a guide to determine the processing conditions to reach high performance films at high growth rates. With proper control of these kinetic parameters, films with critical current densities of 2-2.6 MA cm-2 at 77 K and growth rates between 100-2000 nm s-1 are reached. These growth rates are 1.5-3 orders of magnitude higher than those of conventional methods.

RESUMO

Monitoring the emergence of new SARS-CoV-2 variants is important to detect potential risks of increased transmission or disease severity. We investigated the identification of SARS-CoV-2 variants from real-time reverse transcriptase polymerase chain reaction (RT-PCR) routine diagnostics data. Cycle threshold (Ct) values of positive samples were collected from April 2021 to January 2022 in the Northern Metropolitan Area of Barcelona (n = 15,254). Viral lineage identification from whole genome sequencing (WGS) was available for 4618 (30.3%) of these samples. Pairwise differences in the Ct values between gene targets (ΔCt) were analyzed for variants of concern or interest circulating in our area. A specific delay in the Ct of the N-gene compared to the RdRp-gene (ΔCtNR) was observed for Alpha, Delta, Eta and Omicron. Temporal differences in ΔCtNR correlated with the dynamics of viral replacement of Alpha by Delta and of Delta by Omicron according to WGS results. Using ΔCtNR, prediction of new variants of concern at early stages of circulation was achieved with high sensitivity and specificity (91.1% and 97.8% for Delta; 98.5% and 90.8% for Omicron). Thus, tracking population-wide trends in ΔCt values obtained from routine diagnostics testing in combination with WGS could be useful for real-time management and response to local epidemics.

RESUMO

This paper proposes a first monetary measure of the private costs of celiac disease, including intangible costs (physical symptoms, logistical constraints, etc.) in Switzerland. This auto-immune disease damages the intestine when patients ingest gluten. The only treatment currently available is a gluten-free diet, which implies great nutritional constraints. To get a monetary equivalent of the costs borne by celiac patients, we used a contingent valuation. The scenario suggested to celiac patients a treatment in form of a daily pill, which would allow them to eat normally and avoid any physical pain from celiac disease. Mean Willingness To Pay (WTP) for the treatment is found to be around CHF 87 (approx. USD 87) per month. WTP is positively influenced by direct and indirect costs of the disease. Oppositely, individuals, who find the gluten-free diet healthier are willing to pay less. Finally, unlike symptoms before diagnostic, the current presence or intensity of physical symptoms are found to be insignificant. The latter result can be explained by the fact that, individuals facing stronger symptoms are more likely to adhere strictly to the GFD and hence to reduce their frequency.

RESUMO

Coping strategies are factors that mediate the relationship between interpersonal victimizations and psychological maladjustment. The objectives are as follows: (a) to establish the coping profile of adolescents according to the number of reported interpersonal victimizations; (b) to identify the most victimized adolescents (poly-victims), detecting those with psychological symptoms (nonresilient poly-victims) and those without psychological symptoms (resilient poly-victims), and then to examine any differences in coping strategies between the two groups; (c) to determine the accumulative effect of victimizations on mental health; and (d) to test the mediating role of both approach and avoidance coping between lifetime interpersonal victimizations and symptoms. Participants were 918 community Spanish adolescents (62.7% girls) aged between 14 and 18 years. Measures used were Youth Self-Report, Juvenile Victimization Questionnaire, and Adolescent Coping Orientation for Problem Experiences. The following results were reported: (a) The most victimized adolescents used to a greater degree avoidance coping strategies than nonvictimized adolescents. (b) Resilient poly-victimized adolescents were more likely to seek family support and tended to use more positive reappraisal than nonresilient poly-victimized adolescents. (c) A clear cumulative effect of victimizations on mental health was observed: 45% of the most victimized adolescents (poly-victims) reached clinical range on Youth Self-Report in front of 2% of nonvictimized adolescents. (d) Avoidance coping and more specifically Escaping and Venting feelings strategies played a mediating role between interpersonal victimizations and psychological symptoms. Approach coping had no mediating role, except for Positive reappraisal in girls. In conclusion, the possibility of identifying the coping profile of victimized adolescents may have clinical implications in terms of both prevention and intervention.

RESUMO

The cumulative effect of lifetime interpersonal victimization experiences (e.g., child maltreatment, sexual victimizations, conventional crime, witnessing indirect victimization, peer and sibling victimizations) on posttraumatic stress (PTS) symptoms is an important topic in the scientific literature. The objectives of the present study were: (a) to analyze the relationship between lifetime interpersonal victimizations and PTS symptoms, (b) to determine the most prevalent specific PTS symptoms among poly-victimized adolescents, and (c) to establish the time-based effect of interpersonal victimization experiences that occurred in the last year versus those that occurred years before on current level of PTS symptoms. Gender differences were taken into account for each of these objectives. Participants were 823 Spanish adolescents (63% girls and 37% boys) between 14 and 18 years of age recruited from May 2010 to November 2011 from schools in Barcelona, Spain. The majority (87.6%) was of Spanish nationality. The results highlighted the cumulative effect of interpersonal victimizations on PTS symptoms. Among poly-victims adolescents, the most prevalent PTS symptom was intrusive thoughts, but some differences were observed according to gender. The time-based effect of interpersonal victimizations showed a different pattern for girls and boys. For girls, the victimizing events occurring in past years had more explanatory power of the current PTS symptoms than those that occurred more recently. In boys, the interpersonal victimizing events occurring in the last year had the greater explanatory power. These results may have clinical and therapeutic value.

RESUMO

BACKGROUND: The 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). OBJECTIVE: To 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. METHOD: Using 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. RESULTS: Although 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. CONCLUSIONS: Traumatic 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.

RESUMO

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.
