Abstract
Multiple sclerosis progression and disability can be rated differently by healthcare professionals. Therefore, how physicians perceive the disease can impact treatment decisions. There are no previous studies on this matter. To translate and transculturally validate the Revised Illness Perception Questionnaire for Healthcare Professionals (IPQ-R HP), for use in Brazilian Portuguese. The process used to validate the IPQ-R HP was based on the steps presented in the guide proposed by Dorcas Beaton. The final version of the IPQ-R HP had 38 questions, divided into seven different dimensions to assess the patient's disease. Also, two clinical cases that were representative of real-life patients with multiple sclerosis (MS) were assembled to consider the two main profiles of the disease. We applied the questionnaire to neurologists at the Federal University of São Paulo (UNIFESP) to assess their perception of MS. These doctors also answered a brief survey to establish the profile of the interviewees. For statistical analysis, we used Bayesian CFA models and kappa statistics. The kappa statistics showed a general agreement of 0.4. For the Bayesian CFAs with seven-factor correlation solution, we had a poor fit for case 1 with a 95% confidence interval ranging from -52.893 to 273.797 and a PPP of 0.107. Regarding case 2, the model did not converge even after 50,000 iterations, which indicated that the specified model (i.e. seven-factor correlation solution) for case 2 was inadmissible. Thus, the IPQ-R HP questionnaire in Brazilian Portuguese has not been validated.
Highlights
Multiple sclerosis (MS) is a demyelinating, progressive, degenerative autoimmune disease of the central nervous system (CNS), with prevalence ranging from about 15 to 20/100,000 inhabitants, in Brazil[1]
Validation of the questionnaire The IPQ-R HP questionnaire developed by Arat et al consists of 38 questions in a Likert-scale format, through which participants explain their level of agreement with the topics addressed in terms of five possibilities, ranging from “totally disagree” to “totally agree”
The questions are distributed in seven different dimensions of the disease, called domains of the questionnaire: 1) the consequences of the disease for the patient; 2) the perception of time concerning the duration of the disease, whether it has a prognosis of rapid improvement or not; 3) the patient’s ability to control his/her illness; 4) the effectiveness of some type of treatment that is carried out in the context of controlling the disease; 5) the individual’s understanding of his/her illness; 6) the perception of a possible cyclical nature for the disease, when analyzed over a longer period; and 7) the emotional experience that the patient has regarding his/her illness[6]
Summary
Multiple sclerosis (MS) is a demyelinating, progressive, degenerative autoimmune disease of the central nervous system (CNS), with prevalence ranging from about 15 to 20/100,000 inhabitants, in Brazil[1]. Arat et al demonstrated that doctors who treat patients with systemic lupus erythematosus (SLE) have quite different perceptions of the disease[4,5]. Those authors developed the Illness Perception Questionnaire-Revised for Healthcare Professionals (IPQ-R HP) to highlight differences in perception of SLE. Objective: To translate and transculturally validate the Revised Illness Perception Questionnaire for Healthcare Professionals (IPQ-R HP), for use in Brazilian Portuguese. We applied the questionnaire to neurologists at the Federal University of São Paulo (UNIFESP) to assess their perception of MS These doctors answered a brief survey to establish the profile of the interviewees.
