The Illness Perception Questionnaire-Revised (IPQ-R) has been used extensively across many health conditions to measure patient illness and treatment perceptions. The constructs have an association with treatment adaptation and adherence which, in turn, are considered core factors involved in bariatric surgery outcome. This study examines the factorial validity and internal reliability of a modified (IPQ-R) in bariatric surgery candidates. After wording modifications, participants (N = 310) completed the IPQ-R as part of standard pre-surgery assessments. After removal of two items, confirmatory factor analysis (CFA) supported the original 7-factor solution of the Beliefs scale, with good to marginal subscale internal consistency. Exploratory factor analysis (EFA), with two items removed only partially supported the original 5-factor Causal Attributions scale. Internal consistency was unacceptably low for two subscales. Further research is needed to generate new items which better fit the IPQ-R to this population before research can explore the relevance of illness perceptions.
《疾病感知问卷修订版（IPQ-R）》已广泛应用于多种健康状况，用于测量患者对疾病和治疗的感知。这些结构与治疗适应和依从性有关，而治疗适应和依从性又被认为是肥胖症手术结果的核心因素。本研究检验了肥胖症手术候选者中经过修改的（IPQ-R）的因子有效性和内部可靠性。经过措辞修改后，参与者（N=310）完成了肥胖症手术前评估标准的 IPQ-R。在删除两项后，验证性因子分析（CFA）支持信念量表的原始 7 因素结构，各分量表的内部一致性较好至中等。探索性因子分析（EFA），在删除仅两项后，部分支持原始的 5 因素因果归因量表。两个分量表的内部一致性不可接受地低。在研究探讨疾病认知的相关性之前，需要进一步研究以生成更适合该人群的 IPQ-R 的新项目。
