Project description:ObjectivePatient knowledge of their medicines is closely associated to a better rational use of drugs, thus achieving better health outcomes from their use. The objective of this study is to design and validate a questionnaire to assess the level of knowledge patients have about their medicines.Design(A) Questionnaire: Literature review, some qualitative techniques (expert panel, brainstorming, Delphi method) and some pilot studies. (B) Questionnaire validation.SettingA community pharmacy in the city of Malaga.ParticipantsPatients attending the selected pharmacy, asking for at least one medicine.Main measurementsThe discriminant capacity of the items was assessed. Content and construct validity were analysed using the Spearman's Rho coefficient and Factor Analysis method. Reliability was assessed by measuring internal consistency, equivalence (inter-observer concordance) and test-retest reliability.ResultsThe final questionnaire, with 11 items explaining the different dimensions of knowledge found, was completed by 102 patients (a response rate of 95.3%) with a mean age of 46.6 years (SD 16.70). Mean time to complete it was 4.9 min (SD 2.2). Factor analysis showed a probable structure of 4 factors explaining the 67% of the total variance. The Spearman-Brown Rho coefficient was 0.30 (p<0.05). Cronbach alpha was 0.677, Kappa's coefficient=0.99 and intra-class correlation coefficient=0.745 (95% CI: 0.49-0.87).ConclusionsThe designed questionnaire is dynamic, valid and reliable, being able to measure the level of patient knowledge on the medicines they use.

Project description:ObjectiveFew studies have examined associations between patient knowledge of direct oral anticoagulants (DOAC) and clinical outcomes, mostly because of the lack of validated questionnaires for assessing knowledge. The aim of this study was to develop and validate a questionnaire to self-assess knowledge of DOAC.MethodsTwelve anticoagulation experts participated in the questionnaire development process to ensure content validity. The Knowledge Of Direct Oral Anticoagulants (KODOA)-test was submitted to patients on DOAC and to pharmacists to assess construct validity. Responsiveness was evaluated after educational counseling. Test-retest reliability was assessed to ensure stability over time, and Cronbach's α was calculated for internal reliability. Index of difficulty and item discrimination (D-value) were calculated to assess the performance of single items.ResultsThe KODOA-test contains 15 items with multiple-choice answers. Each correct answer scores 1 point (max. score of 15). The KODOA-test was administered to 32 patients on DOAC and 28 pharmacists. Pharmacists scored significantly higher than patients at baseline (median score 13.3 vs 10.0; p<0.001), supporting construct validity. Patient scores increased significantly after educational counseling (median score 11 [interquartile range 2] vs 14 [interquartile range 3]; p<0.001). Test-retest and Cronbach's α were acceptable with a Pearson's correlation of 0.8 and an α of 0.67. The index of difficulty for most items was satisfactory (0.38-0.72) and the mean D-value was 42.5%.ConclusionThe KODOA-test is a brief, valid, and reliable knowledge self-assessment questionnaire that may be used in clinical trials to investigate associations between knowledge increase and patient-related outcomes.

Project description:BACKGROUND:Prescription and administration of oxygen in emergencies by healthcare providers are reported to be inappropriate in most settings. There is a huge gap in the knowledge of health care providers on various aspects of oxygen therapy, and this may be a barrier to optimal oxygen administration. Hence, it is essential to ascertain providers' knowledge of acute oxygen therapy so that appropriate educational interventions are instituted for better delivery. There is no available validated instrument to assess knowledge of acute oxygen therapy. The study aimed to develop, validate and evaluate the test-retest reliability of a questionnaire to determine the doctors and nurses understanding of acute oxygen therapy. METHODS:This study involved the development of the questionnaire contents by a literature review, assessment of face validity (n = 5), content validity, using a panel of experts (n = 10), item analysis and test-retest reliability among a sample (n = 121) of doctors and nurses. RESULTS:Face validity indicated that the questionnaire was quick to complete (10-15 min), most items were easy to follow and comprehensible. The global content validity index (S-CVI) was 0.85. The test-retest reliability statistics showed a kappa coefficient of 0.546-0.897 (all P<0.001) and percentage agreement of 80-98.3% indicating high temporal stability in the target population. In total, 90% of the items fulfilled the reliability acceptance criteria. Item discrimination analysis showed that most questions were at an acceptable level. The final questionnaire included 37 item questions and eight sections. CONCLUSION:The designed questionnaire is a reliable and valid tool for assessing knowledge of acute oxygen therapy among doctors and nurses.

Project description:UnlabelledTreatment of polycystic liver disease (PLD) focuses on symptom improvement. Generic questionnaires lack sensitivity to capture PLD-related symptoms, a prerequisite to determine effectiveness of therapy. We developed and validated a disease-specific questionnaire that assesses symptoms in PLD (PLD-Q). We identified 16 PLD-related symptoms (total score 0-100 points) by literature review and interviews with patients and clinicians. The developed PLD-Q was validated in Dutch (n = 200) and United States (US; n = 203) PLD patients. We assessed the correlation of PLD-Q total score with European Organization for Research and Treatment of Cancer (EORTC) symptom scale, global health visual analogue scale (VAS) of EQ-5D, and liver volume. To test discriminative validity, we compared PLD-Q total scores of patients with different PLD severity stages (Gigot classification) and PLD-Q total scores of PLD patients with general controls and polycystic kidney disease patients without PLD. Reproducibility was tested by comparing original test scores with 2-week retest scores. In total, 167 Dutch and 124 US patients returned the questionnaire. Correlation between PLD-Q total score and EORTC symptom scale (The Netherlands [NL], r = 0.788; US, r = 0.811) and global health VAS (NL, r = -0.517; US, r = -0.593) was good. There was no correlation of PLD-Q total score with liver volume (NL, r = 0.138; P = 0.236; US, r = 0.254; P = 0.052). Gigot type III individuals scored numerically higher than type II patients (NL, 46 vs. 40; P = 0.089; US, 48 vs. 36; P = 0.055). PLD patients scored higher on the PLD-Q total score than general controls (NL, 42 vs. 17; US, 40 vs. 13 points) and polycystic kidney disease patients without PLD (22 points). Reproducibility of PLD-Q was excellent (NL, r = 0.94; US, 0.96).ConclusionPLD-Q is a valid, reproducible, and sensitive disease-specific questionnaire that can be used to assess PLD-related symptoms in clinical care and future research.

Project description:BackgroundChronic Kidney Disease (CKD) is a complex condition leading to loss of kidney function. The objective of this study was to develop and validate a Knowledge, Attitude, and Practice questionnaire on CKD (CKD-KAP) among practicing physicians in Pakistan since no validated tool was available for the said purpose.MethodsThe study consisted of four phases with phase-I focusing on literature review, phase II was the actual questionnaire development phase, face and content validity was determined in phase III, and finally pilot testing was performed in phase IV to determine validity and reliability. The development phase encompassed a thorough review of literature, focus-group discussion, expert review, and evaluation. The validation phase consisted of content validity, face validity, construct validity, convergent validity, and reliability. The pilot testing was performed by studying the KAP of 100 practicing physicians in tertiary care hospitals in Pakistan. The knowledge section of the validation phase utilized Item Response Theory (IRT) analysis. The attitude and practices sections utilized Exploratory Factor Analysis (EFA) theory. The reliability analysis utilized Cronbach's alpha and correlations.ResultsThe CKD-KAP questionnaire had three main sections: knowledge, attitude, and practice. During the validation, IRT analysis was performed on knowledge, which focused on the measure of the coefficient of discrimination and difficulty of the items; 40 out of 41 knowledge items have both discrimination and difficulty coefficients within an acceptable range. The EFA model was also fitted in the attitude and practices section, and scree plot and Eigenvalues suggested three and four dimensions within the attitude and practices section. The factor loading of all items was found to be acceptable except for one item in attitude which was deleted. The convergent validity demonstrated a significant association between all three sections except knowledge and practices. The reliability (internal consistency) analysis demonstrated Cronbach's alpha values above 0.7 and significant inter-item correlation. The final model of CKD-KAP had 40 knowledge, 13 attitude, and 10 practice items with a combination of both positive as well as negative questions and statements.ConclusionsThe CKD-KAP was found to be psychometrically valid and reliable, hence can be used to determine the knowledge, attitude, and practices of physicians toward chronic kidney disease.

Project description:OBJECTIVE The American Diabetes Association advocates insulin regimens for youth with type 1 diabetes that involve adjusting insulin dose based on carbohydrate intake and blood glucose level. Implementing these regimens requires knowledge about carbohydrate content of foods and subsequent calculations of insulin dose, skills that may be difficult to gauge in practice. Therefore, we sought to develop and validate a questionnaire, the PedCarbQuiz (PCQ), to assess carbohydrate and insulin-dosing knowledge in youth with type 1 diabetes. RESEARCH DESIGN AND METHODS After development by an expert panel, the PCQ was administered to 75 youth with type 1 diabetes or their parents. Reliability was assessed by Cronbach alpha and split-half testing. To assess validity, scores were correlated with A1C, expert assessments, parent educational level, and complexity of insulin regimen. RESULTS PCQ mean score was 87 +/- 9.7% (range 42-98%). Cronbach alpha was 0.88, and correlation of split halves was 0.59 (P < 0.0001). Higher PCQ scores correlated significantly with lower A1C (r = -0.29, P = 0.01) and expert assessments (r = 0.56, P < 0.001). Scores were significantly higher in parents with college degrees than in those without (P = 0.01) and in participants with more complex insulin regimens (P = 0.003). CONCLUSIONS The PCQ is a novel, easily administered instrument to assess knowledge about carbohydrates and insulin dosing calculations. Initial analyses support the reliability and validity of the PCQ.

Project description:BackgroundDelirium is a neuropsychiatric syndrome that can have serious consequences and is often overlooked by healthcare professionals. The level of knowledge about delirium is often insufficient among nursing and medical staff. At the current time there is no suitable questionnaire to record the level of knowledge in German-speaking countries.AimDevelopment of a questionnaire and evaluation of content validity.MethodsFollowing a literature search to identify current best practice, several questionnaires were identified. An already published questionnaire with the dimensions of basic knowledge of delirium and risk factors has been translated, adapted and extended by the dimension of nonpharmacological delirium prevention. Delirium experts assessed the relevance of the questionnaire items in two rounds of reviews. Content validity was calculated using the Content Validity Index (CVI) at item (I-CVI) and scale (S-CVI) level. Additionally, the modified Kappa (k*) was calculated using a lower 95% confidence interval (CI).ResultsThe original 30-item questionnaire was expanded to include 18 delirium prevention items. After the first round of scoring 30 out of 48 items showed good to excellent I‑CVI scores. Considering the comments, 6 items were discarded and 12 were adapted in terms of language and content. In the final version of the questionnaire 41 items with excellent scores remained. The total scale score increased from 0.88 in the first version to 1.0 in the final version. Nurses were identified as the target group, potentially also therapists and medical personnel.ConclusionThe delirium knowledge questionnaire is content-valid.

Project description:ObjectivesThe prevalence of root caries is increasing globally, especially in the elderly population, and even though the number of patients with root caries lesions is augmenting, there are still many discrepancies in how dentists manage this condition. The present study aimed to develop and validate a questionnaire to evaluate how dentists diagnose, record and manage root caries lesions, and to verify the validity and reliability of this questionnaire.Materials and methodsAn expert panel developed a self-administered questionnaire survey with three domains: (1) dentists' knowledge on diagnosis, recording, and managing root caries; (2) information about their current general clinical routines; (3) their demographics. The original English [E] version was translated into three different languages (French [F], German [G], Italian [I]), and subsequently back-translated into English by independent dentists. For the validation, 82 dentists (20-22 for each of the translated versions) accepted to answer the questionnaire at two different time-points (with 1-week interval). The data was quality checked. Construct validity, internal reliability, and intra-class correlation (ICC) were assessed.ResultsSeventy-seven dentists completed the questionnaire twice [E: 17; F: 19; G: 19; I: 22]. The mean ICC (standard deviation) was 0.98(0.03) for E, 0.90(0.12) for F, 0.98 (0.04) for G, and 0.98 (0.01) for I. Overall, the test-retest reliability was excellent (mean ICC (SD): 0.96 (0.08)). Furthermore, the questionnaire demonstrated good internal reliability (inter-observer reliability; Fleiss kappa: overall:0.27(fair); E:0.30 (fair); F: 0.33(fair); G: 0.33(fair); I: 0.89 (almost perfect)).ConclusionThe questionnaire was validated and is suitable to be used in the four languages to assess the knowledge of dentists on diagnosing, recording and managing root caries.Clinical significanceThe present questionnaire was validated and seems to be a good tool to evaluate how dentists diagnose, record, and manage root caries lesions both in its original (English) and its translated (French, German, and Italian) versions.

Project description:A good understanding of a disease facilitates patient-centered management. We aimed to develop and validate a questionnaire to assess inflammatory bowel disease (IBD)-related knowledge and analyze the factors affecting patients' knowledge of IBD. We invited 15 experts to develop and modify an IBD knowledge questionnaires and 709 patients to test the reliability and validity of the questionnaires as well as analyze the factors related to the disease knowledge of patients with IBD. In internal consistency, Cronbach's α coefficients for the common items, ulcerative colitis (UC), and Crohn's disease (CD) knowledge questionnaires were 0.886, 0.89, and 0.886, respectively. In cross-item consistency, Spearman-Brown split coefficients of the common items, UC, and CD knowledge questionnaires were 0.843, 0.812, and 0.812, respectively. In time consistency, the test-retest reliability ICC was 0.862 (P < 0.001). The correlation between researcher scores, IBD-KNOW scores, and the original questionnaire scores was greater than 0.7 (P < 0.001). Multiple linear regression demonstrated that the factors, including disease type, age, body mass index, education level, income, treatment cost, duration of disease, and frequency of visits, affected the IBD patients' knowledge of the disease (P < 0.05). The IBD knowledge questionnaires had good reliability and validity and, therefore, can be used to assess patient knowledge of the disease.

Project description:Low adherence to cystic fibrosis (CF) treatment is associated with poor health outcomes, while knowledge of the disease and medication regimen can positively influence adherence. This study's purpose was to develop and validate a questionnaire to help determine CF medication knowledge of pediatric patients and caregivers. Our questionnaire had 37 items: 22 selected-response and 15 open-response questions. We used validation processes from the Standards for Educational and Psychological Testing. CF experts analyzed validity evidence based on content. Then, the questionnaire was field tested with 17 pediatric patients and 18 caregivers. The correlation between age and medication knowledge was medium (r = .33), but was not significant (P = .189). Cronbach's α for the overall test was .84. Participants thought the questionnaire was important and suitable, with a few minor suggestions to improve wording. Strong validity evidence indicates the questionnaire could be used to assess medication knowledge and allow more personalized education to improve adherence.
