<p>A great deal of research in psychology employs either university student or online crowdsourced convenience samples (Chandler &amp; Shapiro, 2016; Strickland &amp; Stoops, 2019) and there is evidence that these groups differ in meaningful ways (Behrend et al., 2011). This could result in the presence of unaccounted-for measurement differences across convenience sample sources, which may bias results when these groups are compared, or the resulting data are pooled. In this registered report, we used the openly available data from the Many Labs replication projects to test for measurement equivalence across different convenience sample sources. We examined 9 measures that showed acceptable baseline model fit and tested them for non-equivalence across convenience samples from different sources, including university participant pools, MTurk, and Project Implicit. We then examined whether replication results are robust to non-equivalence by fitting partial invariance models and sensitivity analyses of replication results.

No need for them to be recommenders of PCI Registered Reports. Please do not suggest reviewers for whom there might be a conflict of interest. Reviewers are not allowed to review preprints written by close colleagues (with whom they have published in the last four years, with whom they have received joint funding in the last four years, or with whom they are currently writing a manuscript, or submitting a grant proposal), or by family members, friends, or anyone for whom bias might affect the nature of the review - see the code of conduct
