Psychometric evaluation of the Chinese version of the revised illness perception questionnaire for breast cancer-related lymphedema

Abstract

The aim of this study was to modify and test the Chinese version of the Revised Illness Perception Questionnaire to measure the illness perception of breast cancer-related lymphedema among breast cancer survivors. Before the investigation, identity and causal subscales were modified and the wording of the remaining scales was also adjusted. The psychometric properties of this instrument was evaluated using the technique of explore and confirmatory factor analysis. Data from 203 breast cancer survivors was entered into factor analysis. Five causal factors were extracted after removing one item, accounting for 68.02% of the variance in total. An acceptable fit with the data for the proposed seven-factor model was obtained after eliminating three items and resetting seven error covariances. The Cronbach's α values and composite reliability coefficients were acceptable. This measurement is reliable and valid for measuring illness perceptions of breast cancer-related lymphedema in Chinese breast cancer survivors. It could be helpful for further studies that examine the effect of illness perceptions on health-related behaviours, such as lymphedema risk-reduction behaviours in the Chinese cultural context.

Self-Compassion and Symptoms of Depression and Anxiety in Chinese Cancer Patients: the Mediating Role of Illness Perceptions

“…Illness Perception Illness perception was measured by the Illness Perception Questionnaire Revised (IPQ-R) (Hale et al 2007;Moss-Morris et al 2002). The IPQ-R has been validated in Chinese population (Huang et al 2019). Four subscales of the IPQ-R were used: personal control (four items, e.g., the course of my illness depends on me), treatment control (five items, e.g., my treatment can control my illness), timeline cyclical (four items, e.g., my illness is unpredictable), and consequences (six items, e.g., my illness has major consequences on my life).…”

Effect of Illness Perception on Predicting Breast Cancer-related Lymphedema Risk Management Behaviors Among Breast Cancer Patients: a Comparison Between Dimensions and Profiles

“…Illness perception regarding BCRL IP regarding BCRL was measured by a BCRL-speci c Chinese version of the Illness Perception Questionnaire-Revised [CIPQ-R(BCRL)] [11]. It consists of 9 dimensions.…”

“…IP is the main concept of the Common Sense Model (CSM) [9,10] and refers to individuals' views on symptoms, risk factors, time frame (development and duration), consequences, controllability, self-understanding and emotional representations of disease [11,12]. Numerous studies have demonstrated the signi cant impact of IP on patients' health behaviors [12][13][14].…”

Patient Toward Physician Occupational Stigma Scale: Development of the Chinese Version

“… 20 , 21 Moreover, patients’ perception, cognition, and interpretation of the causes, timeline, consequences, and control of illness could affect their medical advice seeking and treatment compliance. 22 For patients, the more perception of illness, the more serious perceived illness, and the more negative attitude toward physicians. 23 Therefore, we hypothesized that the PPOSS was negatively correlated with the WFOTS, and positively correlated with the IUS-12 and the BIPQ.…”
