There remains considerable debate about a theoretically interpretable subscale structure for the Inventory of Interpersonal Problems (IIP). In this paper items are extracted from the IIP to form a 40-item shortened version (the IIP-40) comprising eight subscales, each of five items, which conform to the eight octant positions within Birtchnell's interpersonal octagon: a version of interpersonal theory. The inter-item reliability of the subscale structure is found to be acceptable when tested against a sample of 150 pre-assessment for psychotherapy IIP completions within the Centre for the Study of Psychotherapy (CSP), University of Kent. The face validity is established through acceptable inter-rater reliability scores in an experiment using blind raters. Subscale scores are shown for patients within CSP and are found to be significantly different between genders in the octant positions of Upper Close and Neutral Distant. High scores in the octant position of Upper Distant is found to be a significant predictor of therapeutic drop-out. The results for gender and therapeutic engagement are consistent with other published work in the interpersonal theory field.
关于人际问题量表（IIP）理论上可解释的子量表结构，仍存在大量争议。本文从IIP中提取项目，形成一个包含八个子量表、共40个项目的简版（IIP - 40），每个子量表有五个项目，它们对应于Birtchnell人际八角形内的八个卦限位置：一种人际理论版本。在肯特大学心理治疗研究中心（CSP）对150名接受心理治疗前完成IIP评估的样本进行测试时，发现子量表结构的项目间信度是可接受的。通过在一项使用盲评者的实验中获得可接受的评分者间信度分数，确立了表面效度。给出了CSP患者的子量表分数，发现在“上亲近”和“中性疏远”卦限位置上，不同性别之间存在显著差异。发现在“上疏远”卦限位置上的高分是治疗退出的一个显著预测指标。性别与治疗参与度的结果与人际理论领域其他已发表的研究一致。
