Common misconceptions of p-values are based on certain beliefs and attributions about the significance of the results. Thus, they affect the professionals' decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italian, 30 Chilean) questioned on this topic. Our findings are consistent with previous research and suggest that some participants do not know how to correctly interpret p-values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy. These results highlight the importance of the statistical re-education of researchers. Recommendations for improving statistical cognition are proposed.
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.
ResumenEn este trabajo, me aproximo a algunos marcos teóricos y epistemológicos utilizados en la investigación en distintos ámbitos, desde una perspectiva de género, considerando las implicaciones que tienen en la transformación de la realidad social y en la construcción del conocimiento diversas formas de mirar las diferencias, desigualdades y relaciones entre sexos, y mostrando la relevancia que ha tenido en todo ello la crítica feminista a la ciencia, a través de distintos planteamientos.
