Over a decade of advocacy and policy reforms have attempted to increase the uptake of transparent research practices in the field of psychology; however, their collective impact is unclear. We estimated the prevalence of transparent research practices in (a) all psychology journals (i.e., field-wide); and (b) prominent psychology journals, by manually examining two random samples of 200 empirical articles (N = 400) published in 2022. Most articles had an open access version (field-wide: 74%, 95% confidence intervals 67%-79%; prominent: 71% 64%-77%) and included a funding statement (field-wide: 76% 70%-82%; prominent: 76% 70%-82%); or conflict of interest statement (field-wide: 76% 70%-82%; prominent: 73% 67%-79%). Relatively few articles had a preregistration (field-wide: 7% 2.5%-12%; prominent: 14% 8.5%-19%); materials (field-wide: 16% 9%-24%; prominent: 19% 12%-27%); raw/primary data (field-wide: 14% 7%-21%; prominent: 16% 9.5%-24%); or analysis scripts (field-wide: 8.5% 4.5%-13%; prominent: 14% 9.5%-19%) that were immediately accessible without contacting authors or third parties. In conjunction with prior research (Hardwicke et al., 2022), our results suggest transparency increased moderately from 2017 to 2022. Overall, despite considerable infrastructure improvements, bottom-up advocacy, and top-down policy initiatives, research transparency continues to be widely neglected in psychology.
