contentvalidR: Tools for Substantive and Content Validity Pretesting

Provides quantitative tools for substantive and content-oriented scale pretesting. Implements item-sort indices from Anderson and Gerbing (1991) <doi:10.1037/0021-9010.76.5.732>, exact item-sort inference following Howard and Melloy (2016) <doi:10.1007/s10869-015-9404-y>, empirical interpretation benchmarks from Colquitt et al. (2019) <doi:10.1037/apl0000406>, and the construct-rating procedure of Hinkin and Tracey (1999) <doi:10.1177/109442819922004> with HTC/HTD indices and repeated-measures item screening. The expert-panel workflow combines Aiken's V with score confidence intervals, Lawshe content validity ratios with exact inference, content validity indices with modified kappa and score intervals, item-objective congruence, and panel-level agreement using Krippendorff's alpha as described by Hayes and Krippendorff (2007) <doi:10.1080/19312450709336664>. Also provides judge and rater heterogeneity analysis following the generalizability-theory treatment of content-validity ratings in Crocker, Llabre and Miller (1988) <doi:10.1111/j.1745-3984.1988.tb00309.x>, content-domain coverage and expert-perceived content structure following Sireci and Geisinger (1992) <doi:10.1177/014662169201600102>, consensus and stability across Delphi rounds with between-round weighted kappa following Holey et al. (2007) <doi:10.1186/1471-2288-7-52>, comparison across successive pretest rounds, and exact expert-panel planning. Where published methods compete, users choose among them through arguments with evidence-based defaults. User-facing workflows emphasize interpretable summaries and transparent review recommendations rather than isolated coefficients.
