Development, validation and application of computer-linked knowledge questionnaires in diabetes education.

Multiple choice questionnaires (MCQs) capable of being marked manually or by a newly developed optical mark reader, or by use of an inexpensive inter-active microcomputer system have been developed for the separate assessment of insulin-dependent and non-insulin-dependent patient knowledge. Forty-six insulin-related and non-insulin-related multiple choice questions covering six main areas of knowledge were constructed for inclusion into draft questionnaires. From the responses of a total of 180 completed questionnaires, piloted in 18 randomly selected clinics in 14 Regional Health Authorities in England, psychometric analysis was performed to determine reliability, discrimination coefficients, and facility indices. Seventy-three per cent of insulin-dependent diabetic patients (IDDM) and 92% of non-insulin-dependent diabetic patients (NIDDM) MCQ correct options had facility indices within the acceptable range of 30 to 90%. 82% IDDM and 93% NIDDM correct options had discrimination coefficients exceeding 0.2. Questionnaire reliability (internal consistency) using the Kudor-Richardson (KR20) formula was IDDM 0.87 and NIDDM 0.82. Evidence in support of the IDDM questionnaire's criterion validity was based on significant differences (p less than 0.05) identified between a number of knowledge area scores stratified according to HbA1 levels. Prescriptive correction for screen display and automatic hard copy feedback was designed for both incorrect and omitted question options, providing both educational (patient) and analytical (clinic) documentation. Both technical and psychometric properties of these knowledge assessment instruments should be acceptable for diabetic knowledge evaluation and instruction.

Compliant behaviour: relationship to attitudes and control in diabetic patients.

A study was conducted to examine patient performance of certain safety measures in relation to 'attitude' and glycaemic control. One hundred and thirty consecutive routinely attending insulin-dependent diabetic patients (IDDM) were asked to show a source of sugar and diabetes identification (ID). An attitude scale, developed and psychometrically evaluated with intent to examine 'general attitude to diabetes', was used to study attitudes. Fifty-eight per cent of the IDDM patient sample carried both sugar and ID. The mean HbA1c of these patients (8.4%) was 2% lower (p less than 0.01) compared with patients carrying either ID only (24% of sample: mean HbA1c 10.4%), sugar only (6% of sample: mean HbA1c 10.3%) or neither item (12% of sample: mean HbA1c 10.7%). The general attitude score in these patients was significantly higher if sugar was carried (p less than 0.02) but there was no relationship with HbA1c (p greater than 0.1). A seven-item subcluster representing attitudes to diabetic management was more strongly related to sugar carriage (p less than 0.001) and was inversely correlated with HBA1c (r = 0.252: p less than 0.02). These findings indicate that attitudes to diabetes management may influence specific behavioural elements (i.e. compliance with advice always to carry sugar and ID). However, there was also a significant trend to higher carriage rates for sugar with a higher frequency of perceived hypoglycaemia (p less than 0.05) but no relationship between perceived hypoglycaemia and HbA1c. Absence of sugar of ID appears to represent a useful indicator of poor diabetic control and may assist in the definition of relevant attitudinal differences.

Knowledge profile and control in diabetic patients.

Knowledge about diabetes was assessed using a previously described interactive computer-based questionnaire in 79 patients with insulin-dependent (IDDM) and 72 with non-insulin-dependent (NIDDM) diabetes mellitus routinely attending a single diabetic clinic. Simple linear correlation of total knowledge score with glycosylated haemoglobin (HbA1c) showed no significant relationship for either IDDM (r = 0.12: p = 0.18) or NIDDM (r = 0.15: p = 0.1). However, quintile grouping of knowledge scores showed the mean HbA1c to be significantly higher in the lowest scoring NIDDM quintile (10.6 +/- 0.5: +/- SE) with respect to the pooled mean of all the higher scoring quintiles (9.0 +/- 0.3) (p = 0.027). Mean HbA1c (9.6 +/- 0.5) was also higher in the least knowledgeable IDDM quintile than any other quintile group (range 8.8-9.0) but this was not significant with respect to the pooled mean of higher scoring patients (p greater than 0.1). The mean age of the lowest scoring IDDM quintile group (60.5 +/- 13.9 years) was significantly higher (p less than 0.01) than higher scoring IDDM groups (mean age range 36.5-43.3 years) but age was not significantly related to HbA1c in IDDM subjects. IDDM showed greater knowledge of diabetes than NIDDM but ignorance in key areas was unacceptably high in both diabetic subtypes, indicating that regular knowledge assessment and educational reinforcement may be essential for good diabetic control as well as patient safety, particularly in older IDDM patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Attitudes, knowledge and blood glucose control.

The hypothesis that management-related diabetes knowledge and attitudes may be more directly related to diabetic control than general knowledge of or general attitude towards diabetes is examined. Sixty Type 1 diabetic patients were studied using an itemized knowledge questionnaire and an attitude scale measuring a general attitude to diabetes but containing a previously defined subgroup of items concerned with attitudes to management. A significant linear correlation was found between management-related knowledge (r = -0.39; p less than 0.01) and HbA1c. However, knowledge of insulin, diet, footcare, and glucose monitoring were not significantly correlated with HbA1c, poor control being associated with both very low and very high knowledge status. A significant linear correlation was found between management-related attitudes (but not general attitude) and HbA1c (r = -0.47; p less than 0.01). The multiple regression correlation between HbA1c and both management knowledge and attitudes was -0.51. Most (63%) of the association between knowledge and HbA1c was attributable to attitude. This study provides support for education strategies based upon achieving improved patient attitudes and motivation rather than comprehensive knowledge as the most effective way of improving patient diabetic control.

Knowledge of diabetes in Asians and Europeans with and without diabetes: the Coventry Diabetes Study.

Knowledge about the nature, symptoms, complications, and treatment of diabetes was assessed among United Kingdom Europeans and Asians with and without diabetes during the Coventry Diabetes Study. An open questionnaire was validated for use among Asians and Europeans and a 'Knowledge Index' constructed. The questions were answered by 3814 (87%) of 4395 Asians and 3783 (69%) of 5508 Europeans. Among those with known diabetes, 216 (96%) of 223 Asians and 98 (94%) of 104 Europeans answered the questions. The nature of diabetes was unknown in 30% of Europeans and 44% of Asians with diabetes, and 42% and 67%, respectively, could not name a single complication. Most of those without diabetes were unable to name either a complication (Europeans 66%, Asians 89%) or a single symptom (66% and 83%, respectively). The Knowledge Index was highest in Europeans, increased with increasing educational achievement, and was lowest in non-diabetic subjects without a family history of diabetes. Even those with diabetes had a low Knowledge Index.

Effect of computer-based learning on diabetes knowledge and control.

Two interactive computer-based systems have been evaluated: a teaching program with text and animated graphics and a multiple-choice knowledge-assessment program (KAP) with optional prescriptive feedback. One hundred seventy-four routine-attending insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) patients were allocated to active and control groups to determine the effect of these programs on knowledge and control after a 4- to 6-mo follow-up period. Interactive computer teaching (ICT) resulted in a significant knowledge increment in both IDDM and NIDDM patients (P less than .05), together with a mean fall of 0.8 and 0.7%, respectively, in HbA1c (P less than .05 and P greater than .1), but no changes were observed in respective control groups. The KAP with feedback also produced a significant knowledge increment in both IDDM and NIDDM patients (P less than .05), of similar magnitude to the ICT program, and a mean fall in HbA1c of 1.2 and 1.3%, respectively (P less than .05), with no changes in the corresponding control groups. Even when KAP was used without prescriptive feedback, smaller but significant mean falls in HbA1c of 0.7 and 0.8% (P less than .05) were seen in IDDM and NIDDM patients, respectively, suggesting a motivational effect resulting from program participation.(ABSTRACT TRUNCATED AT 250 WORDS)
