Development of a brief, reliable and valid diet assessment tool for impaired glucose tolerance and diabetes: the UK Diabetes and Diet Questionnaire.

ABSTRACT: OBJECTIVE:Dietary advice is fundamental in the prevention and management of type 2 diabetes (T2DM). Advice is improved by individual assessment but existing methods are time-consuming and require expertise. We developed a twenty-five-item questionnaire, the UK Diabetes and Diet Questionnaire (UKDDQ), for quick assessment of an individual's diet. The present study examined the UKDDQ's repeatability and relative validity compared with 4 d food diaries. DESIGN:The UKDDQ was completed twice with a median 3 d gap (interquartile range=1-7 d) between tests. A 4 d food diary was completed after the second UKDDQ. Diaries were analysed and food groups were mapped on to the UKDDQ. Absolute agreement between total scores was examined using intra-class correlation (ICC). Agreement for individual items was tested with Cohen's weighted kappa (? w). SETTING:South West of England. SUBJECTS:Adults (n 177, 50·3 % women) with, or at high risk for, T2DM; mean age 55·8 (sd 8·6) years, mean BMI 34·4 (sd 7·3) kg/m2; participants were 91 % White British. RESULTS:The UKDDQ showed excellent repeatability (ICC=0·90 (0·82, 0·94)). For individual items, ? w ranged from 0·43 ('savoury pastries') to 0·87 ('vegetables'). Total scores from the UKDDQ and food diaries compared well (ICC=0·54 (0·27, 0·70)). Agreement for individual items varied and was good for 'alcohol' (? w=0·71) and 'breakfast cereals' (? w=0·70), with no agreement for 'vegetables' (? w=0·08) or 'savoury pastries' (? w=0·09). CONCLUSIONS:The UKDDQ is a new British dietary questionnaire with excellent repeatability. Comparisons with food diaries found agreements similar to those for international dietary questionnaires currently in use. It targets foods and habits important in diabetes prevention and management.

Project description:AIMS: Evaluation of the effectiveness of clinical teaching is an important contribution for the quality control of medical teaching. This should be evaluated using a reliable instrument in order to be able to both gauge the status quo and the effects of instruction. In the Stanford Faculty Development Program (SFDP), seven categories have proven to be appropriate: Establishing the Learning Climate, Controlling a Teaching Session, Communication of Goals, Encouraging Understanding and Retention, Evaluation, Feedback and Self-directed Learning. Since 1998, the SFDP26 questionnaire has established itself as an evaluation tool in English speaking countries. To date there is no equivalent German-language questionnaire available which evaluates the overall effectiveness of teaching. QUESTION: Development and theoretical testing of a German-language version of SFDP26 (SFDP26-German),Check the correlation of subscale of SFDPGerman against overall effectiveness of teaching. METHODS: 19 anaesthetists (7 female, 12 male) from the University of Lübeck were evaluated at the end of a teaching seminar on emergency medical care using SFDP-German. The sample consisted of 173 medical students (119 female (68.8%) and 54 male (31.2%), mostly from the fifth semester (6.6%) and sixth semester (80.3%). The mean age of the students was 23±3 years. RESULTS: The discriminatory power of all items ranged between good and excellent (r(it)=0.48-0.75). All subscales displayed good internal consistency (α=0.69-0.92) and significant positive inter-scale correlations (r=0.40-0.70). The subscales and "overall effectiveness of teaching" showed significant correlation, with the highest correlation for the subscale "communication of goals (p< 0.001; r = 0.61). CONCLUSION: The analysis of SFDP26-German confirms high internal consistency. Future research should investigate the effectiveness of the individual categories on the overall effectiveness of teaching and validate according to external criteria.

Project description:IntroductionAssessing patient expectations in orthopaedic surgery has gained significant importance over time. However, there have been only a few studies on how to measure such expectations in hand surgery. Against the backdrop, the study was designed to develop a valid and reliable expectations survey for patients undergoing hand surgery and to identify the correlations between preoperative expectations and postoperative satisfaction.Materials and methodsThis is a three-phase prospective cohort study. In the first phase of the study (146 patients), patient expectations were assessed while developing a draft questionnaire based on frequency and clinical relevance. In the second phase (154 patients newly included), test-retest reliability was measured to ensure test consistency. The Intraclass Correlation Coefficient (ICC) served as a basis for developing the final survey questionnaire. In the third phase, we followed up with patients, who completed the preoperative expectations survey, 3 months after surgery to assess the fulfillment of their expectations. The Pearson correlation method was used to measure the association between preoperative expectations and postoperative satisfaction.ResultsIn the first phase, 146 patients shared 406 different expectations, which were grouped into nine categories. Then, in the second phase, the final survey was populated by questionnaire items under respective category that have revealed strong test-retest reliability (ICC of 0.91). A significant positive correlation between patient expectations and satisfaction was observed (R = 0.181, p = 0.034).ConclusionThe survey was designed to offer a valid and reliable approach for the comprehensive assessment of patient expectations in hand surgery. The survey results show that patients with high expectations tend to be more satisfied with surgical outcomes. It is strongly believed that this approach would serve as a useful tool at a time when patient perspective is taken into account increasingly more in the clinical practice.
