The Revised Illness Perception Questionnaire (IPQ-R) has been used extensively in the study of illness perceptions across different populations. Only few confirmatory factor analytic (CFA) studies of the questionnaire are available. This study examines the construct and discriminant validity of the Turkish IPQ-R in patients with diabetes and cardiovascular disease focusing on the hypothesized seven dimensions of personal controllability, treatment controllability, timeline acute/chronic, timeline cyclical, coherence, consequences and emotional representations.
Methods
302 patients (60.6% women) with a medically confirmed diagnosis of diabetes or cardiovascular disease and a mean age of 53.9âÂÂyears were recruited from out-patient clinics in Turkey and surveyed by means of standardized interviews. Direct maximum likelihood confirmatory factor analysis was conducted.
Results
Several areas of ill-fit were identified in the original measurement model of the IPQ-R. Four items (items 17, 19, 20, and 31) were deleted because of poor factor loadings. Also, two error covariances (between items 33 and 34 and between items 7 and 8) were added and item 6 respecified to obtain a good model fit. The modified 34-item model showed good reliability and discriminant validity.
Conclusion
In accordance with studies on other language adaptations of the questionnaire, we identified certain items of the IPQ-R as potential sources of poor model fit. Their inclusion should be reconsidered in future applications of the questionnaire and researchers should examine whether our reduced set of items is stable across different populations. Our modified 34-item model showed a good reliability and discriminant validity and hence could be a valuable instrument in the assessment of illness perceptions in the Turkish health care setting, provided that the model is confirmed in subsequent research
Evaluation of the physical and emotional effects of the COVID-19 pandemic on patients with fibromyalgia and chronic low back pain: A multicenter cross-sectional controlled study
No full textObjectives: This study aimed to investigate the physical and emotional effects of the coronavirus disease 2019 pandemic in patients with fibromyalgia syndrome (FMS) and chronic low back pain (CLBP) patients.
Patients and methods: The cross-sectional controlled study was performed with 1,360 participants (332 males, 1,028 females; mean age: 42.3±12.5 years; range, 18 to 65 years) between September 2020 and February 2021. The participants were evaluated in three groups: the FMS group (n=465), the CLBP group (n=455), and the healthy control group (n=440). Physical activity, pain levels, and general health status before and during the pandemic were evaluated in all participants. Stress levels were analyzed with the perceived stress scale (PSS) in all groups, and disease activity was analyzed with the fibromyalgia impact questionnaire (FIQ) in patients with FMS.
Results: Patients with FMS had worsened general health status and pain levels during the pandemic compared to the other groups (p< 0.01). The FMS group showed significantly higher PSS scores than those in other groups (p< 01). There was a weak-positive correlation between FIQ and PSS parameters in patients with FMS (p< 0.05, r=0.385).
Conclusion: The general health status, pain, and stress levels of the patients with FMS and CLBP tended to worsen during the pandemic. This high-stress level appeared to affect disease activity in patients with FMS
