The main aim of the study was to assess the factorial structure of the Illness Attitude Scales (IAS). The study population comprised 199 patients referred to cardiological out-patient investigation because of chest pain. The factor analysis revealed three factors of the IAS. Accordingly, we found three subscales, interpreted as health anxiety (HA), illness behavior (IB), and health habits (HH). The internal consistency of the subscales, measured by Cronbach's alpha coefficient, were 0.92, 0.80, and 0.49, respectively. The HA and IB scores were significantly intercorrelated (r = 0.39, p < 0.001), but HH was not significantly correlated with either HA or IB. The HA and IB subscales discriminated between patients with and without panic disorder. The results support previous findings, namely that the IAS comprise two subscales with psychometrically sound properties. Correlational analysis indicated validity of the two subscales. Further studies are needed to confirm the validity.
该研究的主要目的是评估疾病态度量表（IAS）的因子结构。研究对象包括199名因胸痛前来心脏科门诊接受检查的患者。因子分析揭示了IAS的三个因子。据此，我们发现了三个分量表，分别解释为健康焦虑（HA）、疾病行为（IB）和健康习惯（HH）。通过克朗巴哈α系数测量，各分量表的内部一致性分别为0.92、0.80和0.49。HA和IB得分显著相互关联（r = 0.39，p < 0.001），但HH与HA或IB均无显著相关性。HA和IB分量表能够区分有无惊恐障碍的患者。研究结果支持了先前的发现，即IAS包含两个具有良好心理测量学特性的分量表。相关分析表明这两个分量表具有有效性。需要进一步研究来证实其有效性。
