Our goal in this investigation was to evaluate the reliability of scores from the Balanced Inventory of Desirable Responding (BIDR) more comprehensively than in prior research using a generalizability-theory framework based on both dichotomous and polytomous scoring of items. Generalizability coefficients accounting for specific-factor, transient, and random-response error ranged from .64 to .75 for the BIDR's Self-Deception Enhancement (SDE) and Impression Management (IM) subscale scores, and these values were systematically lower than corresponding alpha (.66 to .83) and 1-week test-retest (.78 to .86) coefficients. Polytomous scoring provided higher reliability than dichotomous scoring on nearly all indexes reported. Random-response (8%-17%) and specific factor error (11%-17%) exceeded transient error (3%-6%) for both subscales and scoring methods. Doubling the number of items on a single occasion provided greater improvements in generalizability (.76-.83) than aggregating scores across 2 administrations (.72-.81). Both scoring methods provided reasonably high indexes of consistency (φ coefficients≥.91) at cut scores on the IM scale for detecting faked responses when all sources of error were taken into account. Implications of these results for common uses of the BIDR are discussed.
我们这项研究的目的是使用基于项目二分和多分评分的概化理论框架，比之前的研究更全面地评估平衡意愿反应量表（BIDR）的评分可靠性。涵盖特殊因素、暂态和随机反应误差的概化系数，在 BIDR 的自我欺骗增强（SDE）和印象管理（IM）分量表分数上，从.64 到.75 不等，这些值比相应的α值（.66 到.83）和 1 周重测（.78 到.86）系数系统地低。多分评分在报告的几乎所有指标上都比二分评分提供更高的可靠性。对于两个分量表和评分方法，随机反应（8%-17%）和特殊因素误差（11%-17%）超过暂态误差（3%-6%）。在单个场合上加倍项目数量，比在两次管理中汇总分数（.72-.81），提供更大的概化改进（.76-.83）。在考虑所有误差源的情况下，两种评分方法在 IM 量表的伪造反应检测的分界分数上，都提供了合理高的一致性指数（φ系数≥.91）。讨论了这些结果对 BIDR 的常见使用的影响。
