INTRODUCTION

Education of patients plays an important role in the effective management of diabetes. Formal assessment of diabetes knowledge of patients with diabetes is a prerequisite. Worldwide both the consumer and provider organizations are advocating for improving various methods and strategies for evaluation of the impact of diabetes education in subjects with diabetes [1-3]. However, such efforts for evaluation are hindered mainly because of lack of the formal agreement between the goals and targets [4-9] as well as there is a scarcity of standardized and validated assessment tools [10-12]. To overcome this difficulty, Diabetes Australia has established an Australian national consensus position for the outcomes and indicators to assess the impact of diabetes education in subjects with diabetes [13-14].

As per outcomes and indicators consensus, there are four patient-focused outcomes-knowledge and understanding, self-management, self-determination and psychological adjustment. Diabetes education interventions have the impact on all these four outcomes [13-15]. Eigenmann CA et al. [16] carried out a review to identify and evaluate instruments available for assessing these outcomes and whether these tools are capable and suitable to measure changes in these four main outcomes. Several questionnaires have been developed for assessing knowledge outcome. DKQ was developed in Australia and validated for assessing diabetes knowledge among subjects with diabetes [15]. DKQ [15] is suitable for assessing diabetes knowledge of subjects with type-1 or type-2 diabetes in daily practice, thus it was selected for validation in South Asian context. However, there are continuous changes in standards of diabetes care, guidelines for diabetes care and technologies utilized for diabetes care, thus DKQ requires modification for assuring content accuracy and revalidation is necessary if DKQ is modified [15].

Thus, in order to use DKQ [15] in countries like ours, it needs revision to assure content accuracy for variation in the South Asian region diabetes standards of care, guidelines of care, technologies and cultural context. Adaptation of DKQ [15] prior to utilization of the DKQ for the South Asian context is needed. Thus the objective of this present study was to adapt the diabetes knowledge questionnaire to make it applicable for use in the South Asian region for subjects with type 1 or 2 diabetes for assessing their knowledge outcome following diabetes education intervention.

MATERIALS AND METHODS

Methods

Content validity

Delegates of South Asian Federation of Endocrine Societies summit held on 17th and 18th August 2013, at Hyderabad were invited to participate in the first round Delphi survey [17]. The contents of original DKQ [15] were validated utilizing Delphi survey method [17]. The participants are international expert endocrinologists, diabetologists, physicians, primary care physicians and researchers from five countries: India, Srilanka, Bangladesh, Nepal, and Pakistan. To assess the content validity of the DKQ [15] all the delegates willing to participate were considered. Interested delegates were provided with a request for an appraisal letter to provide ideas about the survey. Data collection form was designed for this present study.

Participants were requested to go through original DKQ [15] and mention their opinion on each of the 15 questions as to whether it should be included in the modified questionnaire on 5 points Likert’s scale [18] (from strongly agree to strongly disagree), whether the question should be included if the phrasing was modified. Participants were also asked to provide their critical comments for changes in each of questions and answer options and their opinion and applicability of DKQ [15] in the South Asian context. The consensus was considered to be reached when at least 67% of participants indicated agree or strongly agree, comments regarding modification, opinion, and applicability of DKQ [15, 17]. All responses were organized, coded, collated and analyzed using descriptive statistical methods with IBM SPSS 19.0 version.

The diabetes knowledge score assessment was set. Scores were calculated for modified DKQ. Points were given to all the right answer selections for each question. However, points were not given for wrong answers. Total scores need to be summed up to obtain diabetes knowledge scores of each subject with diabetes. For assessing their level of knowledge on diabetes these scores can be utilized. Maximum score attainable is 18 and the minimum score is 0. Scores of ≥ 9 considered as satisfactory and scores of<9 considered as unsatisfactory or poor knowledge scores. Greater score demonstrates better diabetes knowledge.

RESULTS

A first round Delphi survey [17] was conducted for assuring the content accuracy of DKQ [15], and for adaptation and modification of DKQ [15] items in the South Asian context. Of the 150 invited delegates, 111 delegates agreed to participate (74 %) in the first round Delphi survey [17]. 39 (26%) did not participate. Reason for non-participation was due to lack of time. The participants’ age range was from 24 to 76 y with a mean age of 43.69 y. They were highly qualified with 48.1% post-graduation and 39.8% post-doctoral qualification (DM) and only 5.6% were graduates from the medical field. Their experience ranged from 0 to 50 y, with mean experience of 13.69 y. Participants practising in the urban location and rural locations are 94.4% and 4.6%, respectively. Participants practising in private and government organization are 62.0% and 30.6%, respectively. Demographic data of participants are presented in table 1.

The consensus was reached for comments for modification for one domain: Modify ideal blood glucose level answer option by conversion of units from mmol to mg/dl and levels accordingly.

Table 3: The consensus was not reached on inclusion of following DKQ [15] questions and comments

The comment on the inclusion of 1 additional question:

1. The importance of adopting a healthier lifestyle.

The inclusion of 1 DKQ [15] question:

1. Diabetes service scheme. Participants (51%) also provided the opinion to modify the diabetes service scheme to suit the South Asian context.

For modification of following comments:

  • 15 questions and its options in diabetes knowledge questionnaire (except for conversion of units from mmol to mg/dl),

  • Delete ethnic-specific term melanoma,

  • Diet items and exercise should be relevant to South Asian context guidelines,

  • Modify to simple terminology and language to suit the South Asian context literacy,

  • Modify answer options for sick day management, hypoglycemia, foot problems and diabetes medication,

  • Modify questions related to HbA1c, ideal blood glucose, diet, sick day management, and foot problem,

  • Add more targets answer options for HbA1c.

The consensus was reached on the inclusion of domains for HbA1c levels, exercise benefits, physical activity, diabetes management, eye, nerve and kidney examination, self-monitoring of blood glucose, hypoglycemia, sick day management, monitoring of treatment and targets for control except for the diabetes service scheme. The consensus was not reached on the comments for modification except for conversion of units from mmol/l to mg/dl. The consensus was reached on the opinion and applicability of DKQ [15] but with some of the changes. Results of summarized comments from the first round Delphi survey [17] are illustrated in table 2 to table 4.

Table 4: Summary of comments for opinion and applicability of DKQ [15]

  • Participants also reached consensus on the usefulness and applicability of diabetes knowledge questionnaire, but it needs to be modified.

Though it is important few comments ranged from 1% to 5% related to following:

  • The questionnaire is valuable, practical instrument and very useful for doctors, chiropodist, pharmacist, and nutritionist.

  • The questionnaire is useful for the doctor to plan management and helpful in conducting the surveys of the population at large in general practices, all (general) clinics, primary health care centers, outpatient departments. Assistance by pharmacist, diabetes educator and counsellor to doctors was considered as valid in this regard.

  • The questionnaire is useful for diabetics, pre-diabetics, patient, family, caretaker, attendant, and the public, society population of all age groups and of any gender.

  • The questionnaire needs translation and re-validation after modification for widespread use for the patient, caretaker, family, society, public education.

Adaptation and modification of the DKQ

Though consensus was not reached few respondents commented in this present study that original DKQ developed by CA Eigenmann et al. [15] is good to assess the level of awareness and knowledge of subjects regarding their disease, only for subjects with good educational status hence can be used for the limited group. And further respondents irrespective of their age, experience, geographic location commented that questionnaire needs to be simplified according to the South Asian subject’s nutrition, lifestyle, literacy, knowledge, socioeconomic status in less technical terms. It should also include questions to make the patient and caretaker aware of our socioeconomic condition and cost-effectiveness of patient education and treatment. The questionnaire should be made more widely available as it is informative and explorative and includes patient for self-management (in their care) through patient education.

Based on constructive suggestions of respondents in the first round Delphi survey [17], a number of questions and answer options of original DKQ [15] were rephrased and modified so as to adapt simpler, short and appropriate language and terms and units for modified DKQ. Responses from the first round Delphi survey [17] were coded; analysis was carried out and collated into modified DKQ. Because of lack of time and complexity of the topic, we could not develop a more structured questionnaire with object-specific questions for the first round Delphi survey [17]. Researcher (KND) adapted and modified DKQ, based on domains answered as ‘strongly agree and agree’ by ≥ 67% participants and comments provided by ≥ 67% participants of the first round Delphi survey [17] and incorporated an appropriate alternative plan for certain a criterion where less than 67% consensus was noticed. However, 1 question on national diabetes service scheme was deleted as the consensus was not reached for the inclusion of this question. And 3 additional questions were incorporated in modified DKQ regarding lifestyle habits, and self-care required to be taken by subjects with diabetes in case of adverse drug reactions or drug-drug interactions and travelling. Endocrinologist (RS) approved the contents of modified DKQ. Final resultant modified DKQ comprises 18 questions on knowledge of diabetes, including its complications and required self-care: 13 multiple choice questions common in subjects with type-1/type-2 diabetes, 4 multiple choice questions for subjects taking oral medication and/or insulin only, and 1 multiple choice question for subjects with type 1 diabetes only. Out of 11 demographic questions, 7 demographic questions of original DKQ [15] were not modified and included in modified DKQ unchanged. Additional demographic questions on educational status, socioeconomic status, sources of medication and language most comfortable to speak, read and understand status are included in modified DKQ. Summary of domains of modified DKQ is presented in table 5.

Table 5: Modified diabetes knowledge questionnaire comprises 18 questions on following domains

13 multiple choice questions common in subjects with type-1 and type-2 diabetes:

1. Diet recommendations,

DISCUSSION

The purpose of this study was to adapt DKQ [15] and make it applicable for use in the South Asian context for assessing diabetes knowledge as an outcome following diabetes education intervention. Acquiring knowledge may not lead to immediate change in behaviour; however, several studies discussed the necessity of assessing knowledge as an outcome of diabetes education intervention because it plays a prominent role in making informed health decision [19-23]. Adequate knowledge of the individual person with diabetes is considered to be a cornerstone to become competent in self-management and in turn prevent further health complications [24]. According to outcomes and indicators, consensus position identified that diabetes education has an impact on diabetes knowledge of subjects with diabetes and it is an outcome of diabetes education. Diabetes knowledge outcome assessment needs to be carried out with appropriate validated instruments [13-16].

Modified DKQ is simple to read and understand, unique with 18-items knowledge questionnaire and seven additional demographic questions and one question each for educational status, socioeconomic status, and the sources of medication, the language most comfortable to speak, read and understand.

The study was conducted utilizing this resultant modified DKQ to assess the impact of diabetes education provided by the pharmacist along with an endocrinologist, in subjects with type 2 diabetes. However, the majority of subjects included in this study were illiterate or with the low level of education, thus modified DKQ was orally administered by conducting face to face interview of subjects with type 2 diabetes. Due to the shortage of resources, the interview could not be recorded [25-26]. An interim analysis was carried out to assess the diabetes knowledge among subjects with type 2 diabetes. Results indicated that diabetes knowledge of subjects with type 2 diabetes was poor. All the questions and answer options of modified DKQ can be easily understood and answered by educated as well as illiterate subjects with diabetes [25]. The study subjects were followed up longitudinally and the final analysis of the results indicated positive impact of diabetes education and counselling intervention on the humanistic outcome, i.e. diabetes knowledge of subjects with type 2 diabetes [26]. Renuga E. et al. conducted the study and assessed knowledge, attitudes, and practices as well as adherence to medication among patients suffering from diabetes. Impact of pharmacist-provided diabetes education on these parameters in these diabetic patients was also assessed. The author concluded that there was an improvement in knowledge, attitudes, and practices of these patients and in turn, it led to improvement in adherence to medication and clinical outcome. The author further concluded that impact of patient education needs to be assessed on a regular basis to achieve improvement in health outcomes [27].

CONCLUSION

Healthcare professionals can utilize this modified DKQ in clinics, outpatient departments, primary health care centres in a busy clinical setting in everyday practice as a research tool for planning, management, in evaluating the impact of diabetes education intervention in subjects with diabetes population of South Asian Countries. Modified DKQ can be utilized for conducting a survey of the population at large, pre-diabetics, patient, family, caretaker, attendant, and the public, society population of all age groups and of any gender in the South Asian Countries context. Diabetes educator, pharmacist, the counsellor can be valid persons to assist doctors in this regard.

LIMITATION

However, rigorous re-validation of the English version of modified DKQ will be carried out.

The text of the modified diabetes knowledge questionnaire and the scoring pattern has been shown in Appendices 1 and 2, respectively.
