This article presents the first systematic review on intimate partner violence (IPV) in self-identified lesbians in same-sex couples. Studies published from January 1990 to December 2013 were analyzed. Of the 687 studies reviewed, 59 were preselected, of which 14 studies were selected that met the inclusion and methodological quality criteria. A summary is presented of the characteristics of the studies, the participants, the prevalence of IPV victimization and perpetration, and its correlates. All the studies were carried out in the United States and used a nonprobabilistic sampling method. The majority of participants were White with a high educational level. The results indicate that all the forms of violence occur, but the most prevalent is emotional/psychological violence. The correlates positively associated with IPV are certain personality characteristics, fusion, previous IPV experience, a family history of violence, and alcohol consumption. This review finds significant limitations in the analyzed literature. Methodological recommendations are made for future studies.

Attribution theory suggests the hypothesis that heterosexuals' attitudes toward homosexual sexual orientation will be more negative when homosexuality is attributed to controllable causes. Our randomized study analyzed (a) whether beliefs about the genetic or environmental etiology of the homosexual sexual orientation can be immediately modified by reading a text and (b) the causal effect of attributions about the controllability (environmental etiology) or noncontrollability (genetic etiology) of homosexual sexual orientation on the rejection of same-sex parenting and their social rights. The sample was composed of 190 Spanish university students with a mean age of 22.07 years (SD = 8.46). The results show that beliefs about the etiology of the sexual orientation could be modified by means of a written text. Furthermore, participants who believed that sexual orientation had a genetic etiology showed greater support for social rights and less rejection of same-sex parenting. However, the effects were detected only when there was a traditional opposition to the family with same-sex parenting. When the opposition was normative, the effect was not statistically significant. Our results can be useful in planning variables for intervention programs designed to foster tolerance toward and normality of sexual diversity.

In this study, we developed a new instrument named Scale Beliefs about Children's Adjustment on Same-Sex Families (SBCASSF). The scale was developed to assess of the adults' beliefs about negative impacts on children who are raised by same-sex parents. An initial pool of 95 items was generated by the authors based on a review of the literature on homophobia and feedback from several focus groups. Research findings, based on a sample of 212 university students (mean age 22 years, SD = 8.28), supported the reliability and validity of the scale. The final versions of the SBCASSF included items reflecting the following two factors: individual opposition (α = .87) and normative opposition (α = .88). Convergent validity of the scale is demonstrated by predictable correlations with beliefs about the cause of same-sex sexual orientation and the support for gay and lesbian rights. Our study reveals a strong positive association between high scores on SBCASSF and beliefs that the origin of same-sex sexual orientation is learned and opposition to gay and lesbian rights.

The empirical research on the COVID-19 epidemic’s consequences suggests a major drop in human mobility and a significant shift in travel patterns across all forms of transportation. We can observe a shift from public transport and an increase in car use, and in some cases also increase of cycling and (less often) walking. Furthermore, it seems that micromobility and, more generally, environmentally friendly and comanaged mobility (including shared services), are gaining ground. In previous research, much attention was paid to the mode choice preferences during lockdown, or early stages of the SARS-CoV-2 situation. The blind spot, and aim of this work, is how long observed changes in mode choice last and when or if we can expect the mode choice to shift back to the situation before the SARS-CoV-2 episodes. The research sample consisted of 636 cases; in total, 10 countries contributed to the sample examined in this study. The data were collected in two phases: the first in the spring of 2020 and the second in the fall of the same year. Results showed that respondents reduced mobility by car, local public transport and walking, but not bicycling during the lockdown, compared to the time before the pandemic started. When the easing came, respondents assessed their own use of the car and walking as almost back to normal. They also reported an increase in the use of public transport, but not reaching the level prior the pandemic by far. It seems that cycling was affected least by the pandemic; use of a bicycle hardly changed at all. As for the implication of our study, it is evident that special attention and actions will be needed to bring citizens back to public transport, as it seems that the impact of the pandemic on public transport use will last much longer than the pandemic itself.

Incorrect interpretations of p values affect professionals’ decisions and jeopardize the quality of psychological interventions and the accumulation of valid scientific knowledge. This study analyzes the errors made by Spanish academic psychologists in interpreting p values. We surveyed academic psychologists about their interpretations of p values. The sample is composed of 418 academic psychologists from Spanish public universities. The mean number of years working as a university professor is 14.16 (SD = 9.39). Our findings suggest that many academic psychologists do not know how to correctly interpret p values. The inverse probability fallacy presents the greatest comprehension problems. Methodology instructors also interpret the significance of the p value erroneously. These results highlight the importance of the statistical re-education of professors.
