Design and validation of a questionnaire to measure the attitudes of hospital staff concerning pandemic influenza

“…We recommend that this questionnaire be assessed in a multi-center study with a larger sample size to increase the reliability of the results and to establish a score model for the questionnaire. Furthermore, an investigation of other confounding factors using qualitative methods, such as soft system methodology (SSM) [9], could potentially improve this questionnaire.…”

“…The first method involves comparing the result with a highly valid measure, such as the work attendance of the participants, to exclude the effect of confounding factors. The second method uses the level of correlation between the dependent and independent variables [9]. The first method was not possible because of the anonymous nature of the study; thus, we applied the second method.…”

“…The last step involved checking the reliability of the questionnaire. There are two methods to measure reliability: test-retest and internal consistency [9]. Because of the anonymous nature of the study, it was impossible to utilize the test-retest method; therefore, the internal consistency of the questionnaire was calculated.…”

Development and preliminary testing of a brief clinical tool to enable daily monitoring of chemotherapy toxicity: The Daily Chemotherapy Toxicity self-Assessment Questionnaire

“…Test-retest reliability of DCTAQ dichotomous responses (yes/no on symptom prevalence) was assessed with % of absolute agreement that indicated the proportion of cases where symptom prevalence was reported the same on the test and retest DCTAQ. Cohen's kappa coefficients (κ value) were also calculated as they produce chance-corrected agreements (Dunn, 2009;Friedman & Wyatt, 2006). In addition, κ values were calculated separately by the type of cancer, gender (colorectal cancer group only) and age (<55 vs. ≥55 years based on a median-split approach) to further examine whether DCTAQ stability remained unaffected by these demographic variables.…”

Bring-your-own-device in medical schools and healthcare facilities: A review of the literature (Preprint)

“…Such a comprehensive policy should at least be inclusive of critical elements such as device management, data management, medical app management, IT capacity, and education and curricular readiness and inclusiveness. Even though the immediate cost benefits of implementing BYOD could initially be negative, the long-term cost benefits might prove to be positive as the systems continue to evolve [74,75].…”
