Abstract

The Trauma Inventory for Partners of Sex Addicts (TIPSA) represents a pioneering attempt to measure trauma in the partners of sex addicts. In this study, we utilized a large sample of TIPSA responses to examine the impact of rescoring empirically disordered response options on error variance and scale reliability. Results suggested that rescoring by collapsing categories in response to empirical response option disordering has a mixed and marginal impact on error variance and scale reliability, and may not be beneficial from a practical standpoint in terms of reducing nuisance variation. Importantly, results also support the conclusion that measurement and diagnosis are distinct endeavors that serve two separate purposes.

摘要

性上瘾者性伴侣的创伤量表（TIPSA）是衡量性上瘾者性伴侣的创伤的开创性尝试。在这项研究中，我们利用大量的TIPSA响应样本来检验记录经验上无序响应选项对误差方差和量表可靠性的影响。结果表明，根据经验响应选项混乱对类别进行折叠进行计分会对误差方差和量表可靠性产生混合性和边际性影响，从实际的角度来看，可能在减少干扰变化方面无益。重要的是，结果还支持以下结论：测量和诊断是为两个不同目的服务的独特方法。
