Attitude toward Sexual Consent and Sext Dissemination Perpetration: The Mediating Role of the Empathy
No full textOur aims were to examine the relationship between the attitude toward sexual consent and sext dissemination perpetration (that is the act of sharing received sexting messages with audiences other than their original recipient) and explore the role of empathy as possible mediator variables of this relationships. We conducted cross-sectional research employing an online survey. Our convenience sample consisted of 940 young adults (79.4% females, 20.6% males, 98.0% Italian, 69.5% heterosexual) with mean age of 24.29 years (SD = 2.89). Our findings indicated a relationship between sext dissemination perpetration and both (a lack of) perceived behavioral control (r =.068) and a positive attitude toward establishing consent (r = −.105). In addition, the relationship between a positive attitude toward establishing consent and sext dissemination perpetration was found to be mediated by empathy, specifically the subdimension of emotional contagion. These findings highlight the complexity of interplay between attitudinal and emotional factors in dissemination of sex, which should be taken into account when designing interventions as well as further research. The implications of these findings for both practice and research are discussed
Bullying in Students with Attention Deficit/Hyperactivity Disorder (ADHD): Analyzing Students’ Social Status and Student–Teacher Relationship Quality
Full text linkThe present study investigated how the quality of teacher–student relationships and students’ social status among peers relate to bullying experiences in children with Attention Deficit/Hyperactivity Disorder (ADHD) and those with typical development (TD). A sample of 135 students (27 with ADHD and 108 with TD; M = 11.37, SD = 1.25) participated. Using a structural equation model, we examined whether ADHD predicted students’ relationships with teachers and peers and whether these variables, in turn, predicted bullying victimization and perpetration. The model showed a good fit. Children with ADHD reported more conflictual relationships with teachers, lower peer preference, and higher social impact compared to their typically developing peers. These relationship characteristics were differentially associated with bullying outcomes, with teacher–student conflict and peer visibility emerging as social risk factors. Although preliminary, the results suggest that the relational context—particularly teacher attention and peer dynamics—may play a critical role in shaping the social experiences of students with ADHD and could have unintended consequences within peer groups
Virtual reality as a medium to elicit empathy: A meta-analysis.
No full textThe current meta-analysis aims to investigate and clarify existing research on virtual reality (VR) as a medium
to elicit empathy. An exhaustive literature search (updated to February 29, 2020) enabled us to locate seven
published articles, yielding a total of nine independent samples. The results reveal statistically significant
positive changes in perspective-taking outcomes after VR exposure (d+ = 0.51 [95 percent CI: 0.15–0.88]) but
they did not note in empathy (d+ = 0.21 [95 percent confidence interval, CI: -0.37–0.79]). A potential limitation
of this work is the low number of studies included. Implications and directions for theoretical development and
empirical research are also discussed
The Generic Conspiracist Beliefs Scale-5: further psychometric evaluation using a United Kingdom-based sample
Full text linkThe 5-item Generic Conspiracist Beliefs Scale (GCB-5) is an abridged version of the 15-item GCBS. It was developed as a global measure of the tendency to engage in non-event-based, conspiracy-related ideation. The GCB-5 is appealing to researchers because of its brevity, which facilitates the measurement of belief in conspiracies alongside multiple constructs and/or in situations where resources are limited (time, etc.). Noting that several studies failed to find an adequate unidimensional fit in the parent GCBS measures across different contexts, the present study further assessed the psychometric properties of the GCB-5. This was necessary since the GCB-5 was validated using North American samples. Thus, to ensure that the GCB-5 was satisfactory for use with samples in the United Kingdom (UK), GCBS/GCB-5 items were administered to a large, representative UK-based sample (N = 1,331), alongside a range of validated conspiracy scales. Confirmatory factor analysis found that a one-factor GCB-5 model produced a good model fit. This specified that the GCB-5 was underpinned by a single dimension. Furthermore, the performance of the GCB-5 was equivalent to the longer GCBS. Both instruments produced similar mean item scores and standard deviations and were comparably positively correlated with concurrent measures. Although the GCB-5 internal reliability was lower than the GCBS, it was good. The GCB-5 also demonstrated configural, metric, and scalar invariance (among gender and age subgroups). This indicated that the GCB-5 was interpreted similarly by men and women and different age groups. Overall, results supported the assertion that the GCB-5 is a psychometrically satisfactory global measure of non-event-based, conspiratorial ideation

No full textEvidence-Based Practice (EBP) is defined as “the integration of the best available research with clinical expertise in the context of patient characteristics, culture, and preferences” (APA, Presidential Task Force on Evidence Based Practice, 2006, p. 273). By definition, EBPP relies on the utilization of scientific research in decision making in an effort to produce the best possible services in clinical practice (Babione, 2010; Sánchez-Meca & Botella, 2010). Consequently, EBP requires to professionals new skills as the ability to critically evaluate and rank the quality of evidence or psychological research to provide the best possible service to patients by incorporating the best evidence into experience or professional judgment and opinions of patients (Sackett et al., 2000).
Within this process of critical evaluation of evidence it is crucial knowing and understanding the process of the Null Hypothesis Significance Testing (NHST) as tool to data analysis, given that this procedure enjoys considerable diffusion in Psychology (Cumming et al., 2007). For example, these authors found that 97% of the articles published in Psychology journals use the NHST. Consequently, knowing how to interpret p values of probability is a core competence of the professionals in Psychology and any discipline where statistical inference is applied.
The p-value linked to the results of a statistical test is the probability of witnessing the observed result or a more extreme value if the null hypothesis was true (Kline, 2013). The definition is clear and precise, however, the misconceptions of the p-value continue to be numerous and repetitive (Badenes-Ribera, Frías-Navarro, & Pascual-Soler, 2015; Falk & Greenbaum, 1995; Haller & Krauss, 2002; Kühberger et al., 2015; Oakes, 1986; Wasserstein & Lazar, 2016).
The most common misconceptions of the p-value are the “inverse probability fallacy”, the “replication fallacy”, the “effect size fallacy” and the “clinical or practical significance fallacy” (Carver, 1978; Cohen, 1994; Harrison et al., 2009; Kline, 2013, Nickerson, 2000; Wasserstein & Lazar, 2016).
The “inverse probability fallacy” is the false belief that the p-value indicates the probability that the null hypothesis (H0) is true, given certain data (Pr(H0| Data)). It means confusing the probability of the result, assuming that the null hypothesis is true, with the probability of the null hypothesis, given certain data (Kline, 2013; Wasserstein & Lazar, 2016).
The “replication fallacy” links p-value to the degree of replicability of the result. Consequently, it is the false belief that the p-value indicate the degree of replicability of the result and its complement, 1-p, is often interpreted as an indication of the exact probability of replication (Carver, 1978; Nickerson, 2000).
The “effect size fallacy” relates statistical significance to the size of the detected effect. Specifically, it involves the false belief that the p-value provides direct information about the effect size (Carver, 1978). That is, supposing that the smaller is the p value are larger the effect sizes. However, the p-value does not report on the magnitude of an effect. The effect size can only be determined by directly estimating its value with the appropriate statistic and its confidence interval (Cumming, 2012; Cumming et al., 2012; Kline, 2013; Wasserstein & Lazar, 2016).
The “clinical or practical significance fallacy” is the false belief that the p-value indicates the importance of the findings (Nickerson, 2000; Wasserstein & Lazar, 2016). In this way, a statistically significant effect is interpreted as an important effect. Nevertheless, a statistically significant result does not indicate that the result is important, in the same way that a non-statistically significant result might still be important.
Given the misconceptions of the p-value and other critics about the use and abuse of NHST (e.g., Monterde-i-Bort et al., 2010; Wasserstein & Lazar, 2016), the American Psychological Association (APA, 2001, 2010a) strongly recommended the reporting of effect sizes (ES) and their confidence intervals (CIs), which, taken together, clearly convey the importance of the research findings (Ferguson, 2009).
There are dozens of effect size measures available (Henson, 2006; Kline, 2013). Nevertheless, they can be classified into two broad groups: measures of mean differences and measures of strength of relations (Frías-Navarro, 2011b; Kline, 2013; Rosnow & Rosenthal, 2009). The former is based on the standardized group mean difference (e. g. Cohen’s d, Glass’s g, Hedges’ g, Cohen’s f); the latter is based on the proportion of variance accounted for or correlation between two variables (e. g., R2/r2, η2, w2).
The most frequently reported ES measures are the unadjusted R2, Cohen’s d, and η2 (e.g., Peng & Chen, 2014). These statistics have been criticized for bias (i.e., they tend to be positively biased), lack of robustness to outliers, and instability under violations of statistical assumptions (Grissom & Kim, 2012; Kline, 2013; Wang & Thompson, 2007).
Finally, within this context of change and methodological advances, systematic, meta-analytic reviews of studies have gained considerable relevance and prevalence in the most prestigious journals (APA, 2010a; Borenstein et al., 2009). Meta-analytic studies offer several advantages over narrative reviews: meta-analysis involves a scientifically-based research process that depends on the rigor and transparence of each of the decisions made during its elaboration, and it can provide a definitive answer about the nature of an effect when there are contradictory results (Borenstein et al., 2009). Meta-analyses facilitate more precise ES estimations, they make it possible to rate the stability of the effects, and they help researchers to contextualize the ES values obtained in their study (Cumming et al., 2012). Nevertheless, meta-analytic studies are not free of bias, such as the publication bias, which is one the greatest threats to the validity of meta-analytic reviews. For example, Ferguson & Branninck (2011) analyzed 91 meta-analytic studies published in American Psychological Association and Association for Psychological Science journal and they found that of the 91 studies analyzed, 26 (41%) reported evidence of publication bias. The consequence of publication bias is an overestimation of effect size (Borenstein et al., 2009; Sánchez-Meca & Marín-Martínez, 2010). Therefore, researchers and readers of meta-analytic studies (such as, practitioner psychologists) should know methods for detecting this bias. In this way, funnel plot is a graphical that is used frequently as publication bias detection method in the health sciences (Sterne et al., 2005).
Therefore, it is needed to carry out research on the degree of methodological knowledge that academic psychologists and practitioner psychologists have about methodological quality of evidence (or psychological research) for proper implementation of EBP approach. This kind of research may bring light about these issues and lead to develop training programs.
Objectives
The first purpose of these works was to detect the statistical reasoning errors that Spanish academic psychologists and Spanish practitioner psychologists make when presented with the results of a statistical inference test. To this end, two questions have been analyzed. The first was the extension of the most common misconceptions of the p value and the second was the extent to which p values are correctly interpreted.
The second purpose was to analyze what Spanish academic psychologists and Spanish practitioner psychologists know about ES, their CIs, and meta-analyses, given that this is one of the main recommendations proposed by the APA (2010) to improve statistical practice and favor the accumulation of knowledge and the replication of findings.
Finally, to check whether the results of the research on misconception of the p-value and the level of knowledge of effect sizes, confidence intervals and meta-analysis conducted in Spanish academic psychologists are reliable, it has been carried out a replication study with a sample of Chilean and Italian academic psychologists.
Method
Procedure
Several cross-sectional studies were carried out through on-line survey. For this purpose, the e-mail addresses of Spanish, Chilean and Italian academic psychologists were found by consulting the webs of the universities at these countries. Potential participants were invited to complete a survey through the use of a CAWI (Computer Assisted Web Interviewing) system. A follow-up message was sent two weeks later to non-respondents. The data collection was performed during the 2013-2014 academic year for Spanish sample and from March to May 2015 for Chilean and Italian sample.
Regarding Spanish practitioner psychologists sample, it was send an e-mail to Spanish Psychological Associations inviting them to participate in the on-line survey on professional practice in Psychology. Potential participants were invited to complete a survey through the use of a CAWI system. A follow-up message it was sent three weeks later. The data collection was performed from May to September 2015.
Participants
The sample of Spanish academic psychologists consisted of 472 participants. The mean number of years of the professors at the University was 13.56 years (SD = 9.27). Men represented 45.8% (n = 216) and women 54.2% (n =256).
The sample of Chilean and Italian academic psychologists was comprised of 194 participants. Of these 194 participants, 159 were Italian and 35 were Chilean. Of the 159 Italians participants, 45.91% were men and 54.09% were women, with a mean age of 47.65 years (SD = 10.47). The mean number of years that the professors had spent in academia was 12.90 years (SD = 10.21). Of the 35 Chilean academic psychologists, men represented 45.71% of the sample and women54.29%. In addition, the mean age of the participants was 43.60 years (SD = 9.17). The mean number of years that the professors had spent in academia was 15 years (SD = 8.61).
Finally, the sample of Spanish practitioner psychologists consisted of 77 participants (68.8% women and 31.2% men, average age of 41.44 years, SD = 9.42).
Instrument
The instrument applied consisted of a survey divided in two sections. The first one included items related to information about sex, age and years of experience as academic psychologist, Psychology knowledge area, kind of university (public/private). In addition, for Spanish practitioner psychologists the first section included items related to years of experience as practitioner psychologist, clinical setting (public or private), and degree of familiarity with EBP movement.
The second section included items related to the knowledge on methodological issues associated with EBP, such as misconceptions of the p-value, level of knowledge about effect size statistics, confidence intervals, meta-analysis studies, and checklists of methodological quality of the studies.
Data analysis
All of the studies included descriptive statistics for the variables under evaluation such as frequencies and percentage. In addition, they included confidence interval for percentages (CIs). To calculate the CIs for percentages we used score methods based on the works of Newcombe (2012).
All analyses were performed with the statistical program IBM SPSS v. 20 for Windows.
Results and conclusions
The findings indicate that the comprehension of many statistical concepts continues to be problematic among Spanish academic and practitioner psychologists, and among Chilean and Italian academic psychologists. The methodological errors and the poor methodological knowledge have been and continue to be a source of direct threat to properly implement the EBP in professional practice and getting valid scientific knowledge.
Regarding misconceptions of the p-value, the “inverse probability fallacy” was the most frequently observed misinterpretation among Spanish, Italian and Chilean academic psychologists. This means that some academic psychologists confuse the probability of obtaining a result or a more extreme result if the null hypothesis was true (Pr(Data|H0) with the probability that the null hypothesis is true given some data (Pr(H0|Data).
In addition, Spanish, Italian and Chilean academic psychologists from the area of Methodology were not immune to erroneous interpretations of the p-value, and this can hinder the statistical training of students and facilitate the transmission of these false beliefs, as well as their perpetuation (Haller & Krauss, 2002; Kirk, 2001; Kline, 2013; Krishnan & Idris, 2014). These findings are consistent with previous studies (Haller & Krauss, 2002; Lecoutre et al., 2003; Monterde-i-Bort et al., 2010).
On the other hand, “clinical or practical significance fallacy” was the most frequently observed misinterpretation among Spanish practitioner psychologists. Nevertheless, a statistically significant result does not indicate that the result is important, in the same way that a non-statistically significant result might still be important (Nickerson, 2000; Wasserstein & Lazar, 2016). Clinical significance refers to the practical or applied value or importance of the effect of an intervention. That is, whether it makes any real (e.g., genuine, palpable, practical, noticeable) difference to the clients or to others with whom they interact in everyday life (Kazdin, 1999, 2008).
Statistical significance tests have a purpose and respond to some problems and not to others. A statistical significance test does not speak about result importance, replicability, or even the probability that a result was due to chance (Carver, 1978). P-value informs us whether an effect exists, but the p-value does not reveal the size of the effect, and neither the clinical/practical significance of the effect (Ferguson, 2009; Sullivan & Feinn, 2012). The effect size can only be determined by directly estimating its value with the appropriate statistic and its confidence interval (Cohen, 1994; Cumming, 2012; Kline, 2013; Wasserstein & Lazar, 2016).
Nevertheless, interpreting a statistically significant result as important or useful, confusing the alpha’s significance level with the probability that the null hypothesis is true, relating p-value to magnitude effect, and believing that the probability of replicating a result is 1-p are erroneous interpretations or false beliefs that continue to exist among academic psychologists and practitioner psychologists, like the results of the studies conducted show.
These misconceptions are interpretation problems and they are not a problem of NHST itself (Leek, 2014). Behind these erroneous interpretations are some beliefs and attributions about the significance of the results. Therefore, it is necessary to improve the statistical education and training of psychologists and the content of statistics textbooks in order to guarantee high quality training of future professionals (Babione, 2010; Cumming, 2012; Kline, 2013; Haller & Krauss, 2002).
Problems in understanding the p value influence the conclusions that professionals draw from their data (Hoekstra et al., 2014), jeopardizing the quality of the results of psychological research (Frías-Navarro, 2011a). The value of the evidence depends on the quality of the statistical analyses and their interpretation (Faulkner et al., 2008).
On the other hand, most of the participants reported using meta-analytic studies in their professional practice and having adequate knowledge about them, including effect size statistics. Nevertheless, they acknowledged having a poor knowledge of graphical displays for meta-analyses, such as, forest plot and funnel plot, which may become in a misinterpretation of results and, therefore, lead to bad practice, taking into account that most of the participants said that they used meta-analytic studies in their professional practice. As several authors point out, the graphical presentation of results is an important part of a meta-analysis and it has become the primary tool for presenting the results of multiple studies on the same research question (Anzures-Cabrera & Higgins, 2010; Borenstein, et al., 2009, Botella & Sánchez-Meca, 2015). In this way, forest plot and funnel plot are graphics used in meta-analytic studies to present pooled effect size estimates and publication bias, respectively.
Publication bias is an important threat to the validity of meta-analytic studies, since meta-analytically derived estimates could be inaccurate, typically overestimated. The funnel plot is used as a publication bias detection method in the health sciences (Sterne et al., 2005). Therefore, researchers, academics, and practitioners must adequately know funnel plots, which is a basic tool of meta-analytic studies to detect bias publication and heterogeneity of effect sizes.
With regard to type of effect size statistic they know, the participants mentioned to a greater degree the effect size statistics from the family of standardized differences in means and η2 (parametric effect size statistics). Nevertheless, these effect size statistics have been criticized for lack of robustness against outliers or departure from normality, and instability under violations of statistical assumptions (Algina et al., 2005; Grissom & Kim, 2012; Kline, 2013, Peng & Chen, 2014; Wang & Thompson, 2007). There are theoretical reasons and empirical evidence that outliers and violations of statistical assumptions are common in practice (Erceg-Hurn & Mirosevich, 2008; Grissom & Kim, 2001). The findings suggest that the most of the Spanish academic psychologists, Spanish practitioner psychologists and Italian and Chilean academic psychologists do not know the alternatives for parametric effect size statistics such as, non-parametric statistics (e.g., Spearman correlation), the robust standardized mean difference (trimmed means and winsorized variances), the probability of superiority (PS), the number needed to treat (NNT), or the area under the ROC Curve (AUC) (Erceg-Hurn & Mirosevich, 2008; Ferguson, 2009; Grissom & Kim, 2012; Keselman et al., 2008; Kraemer & Kupfer, 2006; Peng & Chen, 2014; Wilcox, 2010; Wilcox & Keselman, 2003). As Erceg-Hurn and Mirosevich (2008) pointed out this might be due to lack of exposure to these methods. In this way, “the psychology statistics curriculum, journal articles, popular textbooks, and software are dominated by statistics developed before the 1960s” (op. cit., p.593).
Concerning the methodological quality checklists, again most of the participants said not having knowledge about them. Nevertheless, this is an expanding field and currently there are checklists for primary studies (e.g., CONSORT), for meta-analytic studies (e.g., AMSTAR) and for network meta-analytic studies (e.g., PRISMA-NMA).
On the other hand, the analysis of the researcher’s behavior associated with its methodological practices point out that Spanish, Chilean and Italian academic psychologists who could give a name of effect size statistics presented a profile more close to good statistical practices and design research. Nevertheless, three issues alert on the knowledge that both groups of academics have about effect size and validity of statistical conclusion in general: they associate wrongly effect size with the importance of a finding (clinical or practical significance fallacy), they continue to use in a high proportion p-value expressions that revolve around the oracle of the value of alpha, and they don’t know the purpose of planning a priori statistical power in a study.
Finally, two events that have allowed the science debate on statistical procedures, progress towards a statistical reform and greater transparency and quality of studies, such as the open debate on the uses and abuses of statistical significance tests (which started almost since the beginning of its use) and the development of check tools such checklists (CONSORT, STROBE, PRISMA…), continue to be unknown in a high proportion by Spanish academic psychologists, Spanish practitioner psychologists and Italian and Chilean academic psychologists.
Therefore, the present work provides evidence of the need for statistical training, given the problems related to adequately interpreting the results obtained with the NHST procedure and the poor knowledge of effect size statistical terms, meta-analytic studies and methodological quality checklists that Spanish academic psychologists, Spanish practitioner psychologists and Italian and Chilean academic psychologist have.
The EBP requires having adequate knowledge about the fundamentals of research methodology in order to be able to critically evaluate the tests or evidence that studies include in their reports. The problems in understanding the p-value of probability, effect size statistics and meta-analytic studies influence the conclusions that professionals draw from the data, which jeopardizes the quality of the results of psychological research and a proper implementation of EBP in professional practice. As Faulkner et al. (2008) point out, the value of the evidence depends on the quality of the statistical analyses and their interpretation. Therefore, the interpretation of the findings is a quality filter that cannot be subjected to erroneous beliefs or poor interpretations of the statistical procedure.
Nevertheless, it must be acknowledged several limitations in this series of studies. For instance, the low response rate might affect the representativity of the sample and, therefore, the generalizability of the findings among academic and practitioner psychologists. Nevertheless, it is possible that the participants w
Factores asociados al rol de los cuidadores informales de personas con diversidad funcional y su relación con otras variables
Full text linkLa comprensión de los factores asociados al rol de los cuidadores informales de personas con diversidad funcional es fundamental para mejorar su calidad de vida y bienestar emocional. Esta Tesis Doctoral tiene como objetivo analizar las propiedades psicométricas de instrumentos de medida clave para la evaluación de la carga y la calidad de vida de los cuidadores informales, tales como el CarerQol y el Zarit Burden Interview (ZBI), así como explorar factores protectores y de riesgo relacionados con la experiencia del cuidado. Para alcanzar este propósito general, se han desarrollado cinco estudios específicos que abordan diversas dimensiones del cuidado informal, estructurados en formato de artículos científicos que conforman el compendio de esta Tesis.
El primer estudio consistió en una revisión sistemática de la literatura científica para identificar variables psicosociales e individuales asociadas al rol del cuidador informal. Se examinaron factores protectores, como el apoyo social y la resiliencia, y factores de riesgo, como la ansiedad y el estrés. El segundo, tercer y cuarto estudio se centraron en el análisis de las propiedades psicométricas de los instrumentos de medida CarerQol y ZBI, respectivamente. Se llevaron a cabo análisis de sensibilidad, especificidad y valor predictivo de la versión corta de las puntuaciones de la entrevista Zarit Burden-7. El CarerQol evalúa la calidad de vida y la carga asociadas al cuidado informal, mientras que el ZBI se centra en la medición de la carga percibida por los cuidadores. Para ello, se realizaron metaanálisis de generalización de la fiabilidad y se evaluaron diversas formas de evidencia de validez (convergente, clínica y discriminante) de ambos instrumentos, siguiendo las directrices de la guía COSMIN.
En los tres estudios empíricos analizados, se utilizaron modelos de ecuaciones estructurales con una muestra de cuidadores informales españoles (n = 344). En el primer estudio empírico, que tuvo como objetivo analizar cómo la ansiedad y la depresión predicen el estrés en cuidadores informales y cómo este, a su vez, influye en la carga del cuidador, se identificó que la ansiedad (p = 0.006) y la depresión (p = 0.002) predicen significativamente el estrés, el cual a su vez se asocia con una mayor carga del cuidador (p < 0.001). El segundo estudio, que tuvo como objetivo examinar el papel de la resiliencia y el apoyo social como predictores del comportamiento prosocial y su efecto protector frente a la carga del cuidador, demostró que el apoyo social (p < 0.001) y la resiliencia (p = 0.038) predicen la conducta prosocial, la cual se relaciona negativamente con la carga del cuidador (p < 0.001), sugiriendo que actitudes empáticas y altruistas reducen la percepción de sobrecarga. Además, se halló una correlación positiva entre apoyo social y resiliencia (p = 0.002). En el tercer estudio empírico, que tuvo como objetivo investigar cómo la autoestima, el funcionamiento familiar, la satisfacción vital y la felicidad del cuidador se relacionan e impactan en su bienestar general, se observó que la autoestima (p < 0.001) y el funcionamiento familiar (p = 0.042) se identificaron como predictores significativos de la satisfacción con la vida, la cual actúa como un mediador clave del bienestar del cuidador (p < 0.001).
Finalmente, el octavo estudio consistió en una revisión sistemática sobre la efectividad de intervenciones para reducir la carga y el estrés en cuidadores informales de personas mayores con demencia.
En conclusión, esta Tesis Doctoral aporta evidencia sólida sobre la importancia de evaluar y comprender los factores que influyen en la experiencia del cuidador informal. Los hallazgos permiten no solo validar instrumentos de medida relevantes, sino también identificar mecanismos psicosociales que pueden ser objeto de intervención para mejorar el bienestar de los cuidadores. El trabajo plantea desarrollar apoyos psicosociales que refuercen factores protectores y reduzcan los riesgos del cuidado informal.3 - Salut i Benesta
Vulnerability to violence and abuse among people with disabilities
Full text linkDespite increasing reports of violence against people with disabilities, little is known about this phenomenon in the Italian context. The purpose of this study was to document the self-reported prevalence of abuse in adults with disabilities. The Abuse Assessment Screen - Disability was administrated to 237 Italian individuals with disabilities (49.4% men; 50.6% women), with a mean age of 44.1 years (SD = 14.20). The prevalence of any type of abuse (traditional or disability-related) in the last year was 19.4%.The rate of traditional types of abuse (physical or sexual) was 9.7% in the last year, while for physical abuse the comparable rate was 8.0% and for sexual abuse, 1.7%. Meanwhile, the rate for any type of disability-related abuse was 9.7%; the rate of being prevented from using a wheelchair, cane, respirator or assistive devices was 3.0%, the rate of refusal of help with an important personal need was 6.8%. There were no gender differences in the prevalence of abuse reported. The results of the survey suggest that Italian people with disabilities are often victims of violence by multiple perpetrators. Therefore, primary and secondary prevention efforts should be undertaken to target specifically people with disabilitie
Intimate Partner Violence in Same-Sex Relationships and The Role of Sexual Minority Stressors: A Systematic Review of the Past 10 Years
No full textTo clarify the role of sexual minority stressors on intimate partner violence in same-sex relationships, the authors undertook a systematic review of literature on this topic from 2005 to 2015. Our results indicate different forms of intimate partner violence (physical, psychological, sexual) tend to co-occur in same-sex relationships, bidirectional violence might be a common pattern; and internalized homophobia, degree of 'outness,' stigma consciousness, and experiences of discrimination based on sexual orientation are all related to intimate partner violence. However, these associations are not fully supported by all studies. Our findings emphasize the importance of integrating risk factors typical of sexual minorities with the risk factors predictive of intimate partner violence in heterosexual couples. Therefore, intervention and prevention programs must be designed so as to address and reduce the stress typical of sexual minorities
