[GRIPP2: Spanish Adaptation of the Guidelines to Improve Reporting of Patient and Public Involvement in Research].

Patient and public involvement in research contributes to improving the relevance of studies, although its reporting in the literature is inconsistent and lacks clarity. To enhance the transparency and quality of this involvement, the GRIPP2 (Guidance for Reporting Involvement of Patients and the Public) guidelines were developed, providing specific guidance for systematic and transparent reporting. This methodological note describes the adaptation and translation of these guidelines into Spanish, with the aim of promoting quality, consistency, and transparency in the evidence on patient and public involvement in research. Two versions are presented: GRIPP2 long form, with 34 items aimed at studies where patient and public involvement is the primary focus, and GRIPP2 short form, with 5 items for studies where involvement is a secondary component. The guidelines are primarily intended for researchers and authors wishing to incorporate patient and public involvement in their research, as well as for reviewers and journal editors. Additionally, they may be of interest to research policy makers, funding agencies, health technology assessment bodies, and, of course, patients and the public.
