Diverging perceptions between individual patients with somatic diseases and their healthcare professionals might cause problems in communication and decision-making. To date, no measurement tool is available to compare the illness perceptions between these two groups. The Revised Illness Perception Questionnaire (IPQ-R) is a validated, widely used instrument in many patient populations with somatic conditions. The aim of this study was to adapt the IPQ-R to a healthcare professional's version (IPQ-R HP) and to perform a preliminary evaluation of its validity and reliability.
After adaptation of the IPQ-R HP, 17 doctors from 3 general hospitals and 9 head nurses from a university hospital evaluated the face and content validity of the IPQ-R HP. The results were quantified using the content validity index (CVI) and a modified kappa index (k*). For the reliability measurements a group of nurses from 4 nursing wards participated at 2 time points with an interval of 4 weeks. Internal consistency and test-retest reliability were calculated.
Twenty-eight of the 38 items demonstrated excellent content validity and four items showed good content validity. Four items had a sufficient k* and two items had a low CVI. The average CVI of the 7 dimensions ranged from 0.66 to 0.89. The Cronbach's alpha scores for the seven dimensions, intraclass coefficients and effect size estimates were acceptable.
This preliminary evaluation of the IPQ-R HP shows an acceptable to good validity and reliability. Further exploration of the psychometric properties of this questionnaire in a large cohort of healthcare professionals is warranted.
患有躯体疾病的个体患者与其医护人员之间存在的不同认知可能会导致沟通和决策方面的问题。迄今为止，尚无测量工具可用于比较这两组人群的疾病认知。修订后的疾病认知问卷（IPQ-R）是一种经过验证的、在许多患有躯体疾病的患者群体中广泛使用的工具。本研究的目的是将IPQ-R改编为医护人员版本（IPQ-R HP），并对其有效性和可靠性进行初步评估。
改编IPQ-R HP后，来自3家综合医院的17名医生和1家大学医院的9名护士长对IPQ-R HP的表面效度和内容效度进行了评估。使用内容效度指数（CVI）和修正的kappa指数（k*）对结果进行量化。为了进行可靠性测量，来自4个护理病房的一组护士在间隔4周的两个时间点参与。计算内部一致性和重测信度。
38个条目中的28个显示出优秀的内容效度，4个条目显示出良好的内容效度。4个条目具有足够的k*，2个条目具有较低的CVI。7个维度的平均CVI范围为0.66至0.89。七个维度的Cronbach's alpha分数、组内系数和效应大小估计值均可接受。
对IPQ-R HP的这一初步评估显示出可接受至良好的有效性和可靠性。有必要在大量医护人员队列中进一步探索该问卷的心理测量特性。
