“…These findings differ from those in other studies. Hoelscher, Day, Kelder and Ward [39] reported that the percentage agreement between the School-Based Nutrition Monitoring questionnaire and the 24 h recall ranged from 38% to 89%, and Asaad, Sadegian, Lau, Xu, Soria-Contreras, Bell and Chan [36] reported that six out of nine items (67%) of the Perceived Dietary Adherence Questionnaire designed for diabetic patients were significantly correlated with the 24 h recall. However, the current study showed no significant correlation between the DAQ and the dietary recall for the items regarding skimmed milk and soft drinks.…”

The availability of practical tools to assess dietary knowledge and adherence is essential to evaluate the effectiveness of dietary interventions. The aims of this paper were to develop reliable dietary knowledge and adherence questionnaires, suitable for Lebanese adolescents and their parents, and to estimate the feasibility of conducting studies involving such participants in the school-based setting. Eight Lebanese high schools participated in this study (involving 220 adolescents aged 15–18 years). Self-administered dietary knowledge and adherence questionnaires (the Dietary Knowledge Questionnaire (DKQ) and the Dietary Adherence Questionnaire (DAQ), respectively) were completed by the high school students and their parents. A 24 h recall was additionally administered for the adolescents by a dietitian and a trained interviewer at school, in order to validate the adolescents’ answers in the DAQ. The cognitive interview method was used to qualitatively evaluate the questionnaires. The resulting Cronbach’s alpha ranged from 0.61 to 0.78 for the adolescent questionnaires and from 0.46 to 0.89 for the parental ones. In addition, 23 items (out of 25) of the adolescent DAQ matched with the administered 24 h recall. A significant negative correlation was found between the knowledge score (DKQ) and the unhealthy items of the adolescent DAQ. There was a significant positive correlation between the DKQ of the parents and the knowledge score of their children. This is the first study of dietary questionnaires involving Lebanese high school students from different regions, while also including their parents.

“…The reliability coefficient of the questionnaire was then calculated by 0.91. As well, scores from 1 to 4 were considered (totally disagree 1, disagree 2, agree 3, totally agree 4) for the questionnaire items based on a 4-point Likert-type scale.The fourth part of the questionnaire was Perceived Dietary Adherence Questionnaire (PDAQ) focused on proper dietary adherence whose validity and reliability had been examined by Asaad et al [27] in the Canadian population in 2015. The given questionnaire included 9 items based on the Canadian Diabetes Association’s Clinical Nutrition Guidelines designed and extracted from Canada’s Food Guide.…”

BackgroundManaging type 2 diabetes (T2D) is assumed to be heavily dependent on patients’ active participation in their own self-care behaviors including prescribed diets.ObjectivesThe purpose of the present study was to investigate the effectiveness of educational intervention based on psychological factors on nutritional behaviors as well as levels of fasting blood sugar (FBS) and glycated hemoglobin (HbA1c) in patients with T2D referring to diabetes clinics and healthcare centers in the city of Izeh, Iran.MethodsA total number of 145 patients were recruited in this clinical trial and then randomly assigned to two groups of intervention (n = 73 individuals) and control (n = 72 individuals). After that, a researcher-made multi-part questionnaire including a demographic characteristics information form, a nutritional perceptions and beliefs questionnaire; a scale measuring fears, concerns, and discomforts associated with diabetic diet, as well as the valid and reliable Perceived Dietary Adherence Questionnaire were used to collect the required data before and 3 months after the completion of the educational intervention. To this end, the patients in the intervention group attended an educational program for eight sessions but the individuals in the control group only received routine services. Data analysis was also conducted using the SPSS Statistics (Version 18) and via descriptive and inferential statistics.ResultsThe findings revealed that the mean scores of the sub-groups of nutritional perceptions and beliefs (but not exaggerated ones) in the patients assigned to the intervention group were significantly higher than those in the control group after 3 months (p = 0.001). As well, the mean scores of the sub-groups of fears, concerns, and discomforts in patients as well as exaggerated beliefs witnessed a significant decrease in the intervention group compared to those in the control group (p = 0.001) 3 months after the educational intervention. Furthermore, the mean scores of adherence to a healthy diet in the intervention group had significantly increased compared to those in the control group. There was correspondingly a significant descending trend in the average levels of fasting blood sugar (FBS) and glycated hemoglobin (HbA1c) in the intervention group compared to those obtained in the control group (p = 0.001).ConclusionThe results of this study shed light on the importance of the effectiveness of psychological factors on achieving health outcomes in patients with type 2 diabetes (T2D). Moreover, a new combination of diet-related psychological factors in patients with diabetes was introduced in the present study.Trial registration IRCT. IRCT20180308039008N1.

“…Diet quality was assessed by calculating the Healthy Eating Index (HEI) adapted to the Canadian population [26]. Participants’ perceptions of their dietary adherence to CDA Nutrition Therapy Guidelines were assessed by the Perceived Dietary Adherence Questionnaire (PDAQ) [27]. Prior to and post-intervention, participants were asked to report all the medications that they used (name of drug, frequency of use and dose) as a potential confounder of intervention outcomes.…”

Type 2 diabetes (T2D) patients often find integrating a new dietary pattern into their lifestyle challenging; therefore, the PANDA (Physical Activity and Nutrition for Diabetes in Alberta) menu plan intervention was developed to help people incorporate the Canadian Diabetes Association (CDA) nutrition therapy guidelines into their daily lives. The menu plan focused on recipes and foods that were accessible, available and acceptable to Albertans. The objective was to evaluate the effectiveness of the intervention on blood glucose control and dietary adherence and quality among patients with T2D. Participants with T2D (n = 73) enrolled in a single-arm incorporating interactive education based on a four-week menu plan that incorporated the recommendations of the CDA nutrition therapy guidelines. Post-intervention follow-up was conducted at three and six months. After three months, there were beneficial changes in A1c (−0.7%), body mass index (BMI, −0.6 kg/m2), diastolic blood pressure (−4 mmHg), total cholesterol (−63 mg/dL), HDL- (+28 mg/dL) and LDL-cholesterol (−89 mg/dL), Healthy Eating Index (+2.1 score) and perceived dietary adherence (+8.5 score) (all p < 0.05). The significant improvements in A1c, BMI and lipids were maintained at six months. The PANDA menu plan intervention was effective in improving glycemic control and diet quality. The results suggest that a dietary intervention incorporating interactive education sessions focused on menu planning with familiar, accessible foods may be effective for diabetes management.
