Schriescheim et al (1989) wrote an an article where they conducted three studies exploring the effect of two questionnaire formats (grouping versus randomized items) on internal consistency and test-retest reliability, convergent and discriminant validity, and accuracy in respondent-provided descriptions.

Conclusion: They found that neither format (group/random) is superior to the other on any of the examined psychometric properties, although a weak trend showed that the grouped item format produced slightly superior measurement properties, but did not support the usefulness of grouping.
