The work carried out within the REME Research Unit aims at developing, improving and evaluating quantitative methods. We analyse, in particular, aspects of the research design and statistical studies related to Applied Psychology, as well as study and reflect on the key elements that help psychology professionals approach their work from the perspective of evidence-based practice. Our team has developed a programme named ‘Plan de Redacción y Lectura Crítica de la Investigación Científica (PRe)’ (writing and critical reading of scientific research programme). This is directed towards students and scientists, with the main goal of providing fundamental competences of writing and active reading of literature, as well as raising awareness about the issues that currently (and cyclically, throughout the history of science) affect the quality of the evidence found through research. The PRe programme treats topics such as the integrity of scientific staff, Questionable Research Practices (PIC), the benefits of Open Sciences, research culture, publication bias, the study of the risk of bias in primary and secondary studies, or transparency in the writing of reports and articles. In this sense, our Research Unit has also become an Integrity Principles in Science Laboratory (Pi-Science).
