Read the rest of the paper, that was study 1a. They ran multiple sets of experiments with much larger sets, cross-correlated their result sets, ran a solid confirmatory factor analysis, ran sub-assessments (like attachment style) to make sure they weren't rediscovering an already known factor, and reran the same inventory assessments with each group. I mean it is only one paper, but for a Social Psychology paper the math and methods are pretty solid. Given the institutions involved in the paper, I would expect this paper to at least pass the smell test for its own field (even if the results are garbage). I'm normally quite bearish on Social Psych as well, btw.
