The primary aim was to explore the factor structure of the Illness Behaviour Questionnaire (IBQ) and the generalisability of the derived dimensions to both general community members and four chronic illness groups. A questionnaire was administered to 675 participants, comprising 344 from the community, 80 with asthma, 95 with diabetes, 79 with chronic pain and 77 with chronic fatigue syndrome (CFS). Illness severity was calculated for all chronic illness participants (self-rated health for community members). Three IBQ scales were derived following an exploratory factor analysis for the whole sample: Affirmation of Illness (α = 0.71 (CFS)-0.79 (asthma, diabetes)), Concern for Health (α = 0.71 (asthma)-0.78 (pain)) and General Affective State (α = 0.70 (CFS)-0.80 (asthma)). Patterns of response across the five samples, and intercorrelations among the new scales and the original seven scales, were largely in accord with expectation. Long-standing criticisms of the IBQ were addressed by using systematic statistical principles to identify meaningful and psychometrically sound IBQ dimensions. The derived structure offers a more parsimonious account of possible illness responses, with the availability of a more concise yet informative index of abnormal illness behaviour having practical utility for researchers and clinicians alike.
主要目的是探索疾病行为问卷（IBQ）的因素结构，以及所得到的维度在普通社区成员和四种慢性疾病群体中的可推广性。向 675 名参与者发放了问卷，其中包括 344 名社区成员、80 名哮喘患者、95 名糖尿病患者、79 名慢性疼痛患者和 77 名慢性疲劳综合征（CFS）患者。所有慢性疾病参与者（社区成员的自我评估健康状况）的疾病严重程度都进行了计算。对整个样本进行探索性因素分析后得出了三个 IBQ 量表：疾病肯定（α = 0.71（CFS）-0.79（哮喘、糖尿病））、健康关注（α = 0.71（哮喘）-0.78（疼痛））和一般情感状态（α = 0.70（CFS）-0.80（哮喘））。五个样本中的反应模式，以及新量表与原始七个量表之间的相互关系，在很大程度上符合预期。通过使用系统的统计原则来识别有意义且具有心理测量学意义的 IBQ 维度，解决了 IBQ 长期存在的批评。所得到的结构提供了一种更简洁的可能疾病反应解释，具有异常疾病行为的更简洁但信息丰富的指数，对研究人员和临床医生都具有实际应用价值。
