ABSTRACT

BACKGROUND AND OBJECTIVES:

Socio-educational tools aimed at the population with chronic pain can help in the knowledge about trigger mechanisms, beliefs, and attitudes towards pain that may be useful in their control. In addition to developing them, it is necessary to evaluate whether these tools are valid for therapeutic use. The objective of this study was to describe the validation process of an educational booklet for people with chronic pain.

METHODS:

This study was developed in three stages: questionnaires for the evaluation of the booklet by patients and professionals, interview, and content validation. The sample consisted of 60 patients with chronic pain and six professionals specialized in your treatment. For validation, the Content Validity Index per items was used considering a score greater than or equal to 80%.

RESULTS:

All six domains evaluated in the booklet obtained a Content Validity Index per items score greater than 80%. The Content Validity Index per items overall rate of the domains evaluated by the patients was 88% while for the health professionals it was 92%.

CONCLUSION:

The EducaDor booklet showed to be valid for use in the education of patients with chronic pain.

INTRODUCTION

Chronic pain (CP) is defined as "a stressful experience associated with an actual or potential tissue injury with sensory, emotional, cognitive and social components"1 that lasts for more than six months, with daily or almost daily frequency. In Brazil, CP is considered a public health problem with a high incidence and prevalence2. CP impacts more than 40% of the Brazilian population3,4.

The multifactorial nature of CP calls the need for new preventive and therapeutic modalities for its control. Thus, the use of multidimensional approaches involving biological, psychological, and social aspects, as well as health education activities that address these biopsychosocial aspects may result in immediate and late benefits. This effect was superior to those obtained with conventional interventions, such as drugs and physiotherapy5,6.

Making people aware of the meaning of pain, how it behaves, its common causes, risk factors, and how to prevent or treat it effectively may contribute to control the symptoms and optimize the use of health services6-8.

Different methods have been adopted to carry out educational processes in the health area, including the distribution of booklets, personal construction studies, videos, group activities, and lectures6,9-11. However, the literature is scarce on approaches that use written educational materials, such as booklets involving guidelines for the treatment of patients with CP. Through booklets, patients, family and caregivers can get the knowledge about the situations that trigger pain and what to do to help minimize it12,13.

Thinking about this, Mendez et al.14 developed a booklet for education in CP, called EducaDor, which goes beyond the purely biomedical model of their approach. The booklet explains pain from its concept to its processing, simply and objectively, and proposing coping strategies. Aiming at the use of the booklet in an extended way in clinical practice, the objective of this study was to validate a socio-educative booklet on CP by patients and health professionals.

METHODS

This is a study to validate a light technology in health, conducted at the Pain Outpatient Clinic of the University Hospital Professor Edgar Santos (HUPES) of the Federal University of Bahia (UFBA), from June 2015 to November 2016.

Semi-structured questionnaires were elaborated and applied in a voluntary sample of patients with CP and health professionals with experience in assisting this profile of patients to validate the booklet. Among the professional team of the outpatient clinic, six professional who met the eligibility criteria were selected as judges, as suggested by Joventino et al.15. The validation by the target audience was done with 10 patients per health professional, totaling 60 patients.

Patients enrolled in the HUPES/UFBA Pain Outpatient Clinic were included, with a diagnosis of CP, literate, aged between 18 and 60 years. Those who did not understand the evaluation instrument were excluded. We included healthcare professionals with a minimum of 5 years of experience in the care of patients with CP.

This work consisted of three steps: elaboration of the questionnaires for validation of the booklet by the judges, interview, and validation of the content.

Elaboration of the questionnaires

The questionnaires were elaborated based on the evaluation criteria to validate educational material, the Suitability Assessment of Materials (SAM)16. This method consists of evaluating the written content in terms of understanding, described as the relative difficulty in understanding the meaning. For this, the questions applied had as answer option the degree of understanding, and these answers were graded in the Likert scale from "1" to "4", corresponding to "no," "little," "considerable" and "totally, respectively.

Interview

Four members of the research group conducted the interview. Initially, the purpose of the study and a brief introduction about the content of the booklet was presented to the volunteers by agreeing to participate and being in compliance with the inclusion and exclusion criteria, the volunteer signed the Free and Informed Consent Form (FICT) and received a copy of the booklet to read. The reading occurred in a waiting room and the time available to do it was according to the individual need of each judge. The evaluation questionnaire was applied immediately after. The evaluators guaranteed the confidentiality of the answers by not identifying the judges, and the answers were filed for later analysis.

Content validation

The Content Validity Index (CVI) was used to validate the educational pain booklet by items17,18 considering a cut-off point for approval of equal or above 78% when there are seven or more judges and 86% for six judges19. The CVI evaluates the proportion of evaluators who judged certain aspects of the booklet as satisfactory, which were assessed through the structured questionnaire. The items of the questionnaires that had a score of 1 and 2 were classified as unsatisfactory answers, and those with a score of 3 or 4 were classified as satisfactory. The final score was calculated from the number of evaluators who judged each item as satisfactory, divided by the number of evaluators:

CVI=numberofanswers3or4totalnumberofevaluators

This study was approved by the Research Ethics Committee of the Institute of Health Sciences of UFBA of 2015 with number 44318415.7.0000.5662. All the recommendations of Resolution 466/12 of the National Health Council that comply with the Declaration of Helsinki have been expressly complied with.

RESULTS

For the validation process of the booklet, 60 patients with CP and six health professionals with experience in the care of this population were interviewed. Table 1 shows the level of education and gender of the judges interviewed. Most of the interviewed patients were female (83.3%) with complete elementary school (38.3%) and secondary school (38.3%). As for the health professionals, 83.3% had complete higher education (Table 1), while only 6 (10.0%) patients had this level of education.

Structured questionnaires were prepared for the validation of the educational booklet by the judges. One questionnaire was directed to patients and one to health professionals.

The questionnaire for patients (Figure 1A) had five domains: content, presentation of the literature, illustration, readability, printing, and overall evaluation. The questionnaire for health professionals (Figure 1B) had six domains, the ones already cited plus scientific accuracy. The questionnaires for patients and health professionals had 22 and 24 questions, respectively. After the questions of each domain, there was some space available for comments and suggestions for adjustments by the judges.

DISCUSSION

This study aimed to validate a socio-educational material on CP in the format of a booklet that have been developed in a previous study14, to check if it could be applied as a health education resource, from the perspective of patients and specialized professionals. The final scores of the evaluation reached a level of excellence in the agreement of the judges and indicated that the EducaDor booklet is valid and can be used as a therapeutic resource.

Several factors have been pointed out as predictors of CP, among them, be female and have a low level of schooling20,21. Differences in pain perception between genders are well evidenced in the literature22-25. Experimental studies with animals26,27 and humans28, support the hypothesis that women have higher pain perception because they are more exposed to specific situations such as dysmenorrhea and childbirth. The education level lower than 11 years has been pointed out as the major risk factor for this condition29. The sociodemographic characteristics of the sample of patients interviewed were compatible with the profile cited in these previous studies. Precisely because of this profile, the use of socio-educational materials may be fundamental for health literacy, which may have an impact on pain relief30.

The professionals interviewed attributed 100% scientific accuracy to the material evaluated. This score gives confidence for the immediate adoption of the material by other professionals in clinical practice. Careful professionals have uncertainties in reinforcing erroneous beliefs commonly found in websites and instruction materials not based on science. Due to the multifactorial characteristic of the CP and the information available on the internet, coping with the problem has been a challenge for health professionals9. The knowledge about pain with a scientific basis comes as a supporting strategy for the treatment of people with CP. Pain education programs use approaches that allow providing information on pain etiology, nosology and pain pathophysiology. This type of approach makes it possible to equip patients for greater awareness of the different causal and aggravating factors. The knowledge acts in the social representations and the experiences of the disease, facilitating its recovery31.

Ease of reading and printing were the best-evaluated items, both by professionals and patients. This result shows the importance of careful preparation of the printed material so that it has sufficient durability to be consulted several times and fulfill its purpose8. A systematic review32 pointed out that socio-educational programs have an influence on the improvement of pain and movement, and in minimizing disabilities and reducing the utilization of health services. The recognition of the quality of the "EducaDor" booklet may indicate that this tool can be an aid in the treatment of CP in Brazil, due to the biopsychosocial aspects involved14.

The elaboration of printed educational material is a means of communication between the health professional and the patient that not only requires a clear identification of the target audience but a direct and intuitive way to convey the content addressed. To raise and keep the interest of the reader, one must consider the language, layout, and illustration. However, it is the illustration that will, by far, ensure the readability and the comprehension of a text33. In the "content" domain of the questionnaire, patients and professionals were asked about the clarity of the purpose of the booklet, the comprehension of the text, the order of the texts and the need for information. Approximately 87% of the patients and 92% of the professionals judged the content to be satisfactory. However, the illustration had the lowest score in the patients' view (84%). Although it is a satisfactory level, future editions should consider the possibility of improving the illustrations. Limit the number of illustrations, make them simpler and more representative, emphasizing important points in the text description, listing real-life events are strategies that facilitate the communication of content to the reader. Thus, people with low schooling can benefit from these materials and types of language33.

"EducaDor" tried to explain the concept of pain in a clear and detailed way, addressing acute and chronic pain, their characteristics and differences, processing, coping approaches and misbeliefs that patients and caregivers have concerning pain. So far, there are no validated educational booklets for patients with CP in Brazil. However, several educational materials are available on websites for this population. In addition to addressing concepts, these materials also discuss sleep quality, anxiety, and pharmacological and non-pharmacological treatments. Increasing evidence shows that knowing the neurophysiology of pain helps to reduce the incapacity and catastrophization of patients with CP, improving physical movements and compliance with several therapies34. Although the "EducaDor" does not address the treatments for CP, the themes are explained from the stories, questions, and fears reported by this population. The text presents reports of experiences of people who live with pain, allowing the reader to identify himself with the content exposed.

As a limitation, we can mention that this booklet is validated for only one reference pain center, located in Salvador, Bahia, that has specific sociocultural characteristics. Moreover, the small number of health professionals interviewed may not express what the experts from other regions would consider relevant. It is suggested that the EducaDor booklet is validated in other pain centers in other Brazilian regions and its effect on the intensity and other phenomena related to CP be tested in a randomized clinical trial.

CONCLUSION

Patients suffering from chronic pain and health professionals specialized in its treatment validated the content, the adopted language, the topics covered and the illustrations of the EducaDor booklet.
