Background The Australian/Canadian Osteoarthritis Hand Index (AUSCAN), the Patient-Rated Wrist/Hand Evaluation (PRWHE) and the Thumb Disability Exam (TDX) are patient-reported outcome measures (PROM) designed to assess pain and hand function in patients with hand arthritis, hand pain and disability, or thumb pathology respectively. This study evaluated the content validity of AUSCAN, PRWHE and TDX in people with hand arthritis. Methods This study enrolled participants with hand arthritis to rate the items of all 3 PROM in terms of relevance and clarity. The Content Validity Index (CVI) was computed for each item in each scale (I-CVI) as well as for the overall scale (S-CVI). Kappa was used to determine the inter-rater agreement among the raters. Results Overall, 64 individuals with hand arthritis (27% with OA, 67% with rheumatoid arthritis and 6% with psoriatic arthritis) participated in the study. The I-CVI for all items and all scales were very high (I-CVI > 0.76) and the modified Kappa agreement among the raters demonstrated excellent agreement (k > 0.76). The S-CVI for all PROMs was very high for relevance (AUSCAN = 0.92, 95% CI 0.90 to 0.94; PRWHE = 0.85, 95% CI 0.82 to 0.88 and TDX = 0.87, 95% CI 0.85 to 0.89) and for clarity (AUSCAN = 0.99, 95% CI 0.98 to 1.00; PRWHE = 0.95, 95% CI 0.93 to 0.97 and TDX = 0.91, 95% CI 0.89 to 0.94), respectively. Conclusions This study demonstrated very high content validity indices for the AUSCAN, PRWHE and TDX; with strong consensus across raters. This augments prior studies demonstrating appropriate statistical measurement properties, to provide confidence that all three measures assess important patient concepts of pain and disability.
INTRODUCTIONIn the ongoing coronavirus disease 2019 (COVID-19) pandemic, even though vaccines have been rolled out and the vaccination campaigns in some countries have already been followed by a decline in number and severity of cases, non-pharmaceutical interventions (NPI) are still playing an important role on COVID-19 management (e.g. social distancing) that are imposed by the authorities and require the public's adherence and behavioral adjustment. This study aims to identify factors that affect the general public's attitudes towards the importance of NPI in Greece. METHODS This prevalence study, enrolled 657 adults from the general Greek population in order to assess their beliefs and identify possible factors that influence their perceptions of NPI. All associations were assessed through multivariate logistic regression. RESULTS Overall, Greeks considered NPI important for health protection. The participants who were less likely to consider NPI important were men compared to women (OR=1.64; 95% CI: 1.15-2.36, p=0.007), people aged <40 years compared to those ≥40 years (OR=0.48; 95% CI: 0.34-0.68, p<0.001), and people who did not choose the Hellenic National Public Health Organization (NPHO) to get informed about COVID-19 compared to other sources (OR=0.65; 95% CI: 0.46-0.92, p=0.014). CONCLUSIONS This study profiled Greek people who do and do not consider NPI important, primarily on their demographic characteristics. Focused communicational strategies in certain population subgroups are recommended.
Background: In the early stages of coronavirus disease 2019 (COVID-19) pandemic, while effective pharmaceutical approaches are pending, COVID-19 management relies primarily on non-pharmaceutical interventions (NPIs), such as social distancing,which requirepublic's engagement and behavioral adjustment. This study aims to evaluate public's perceived importance of the NPIs imposed for COVID-19 control in personal and public health protection in Greece. Methods: This cross-sectional online study, enrolled 657 adult participants from the general Greek population in order to assess their beliefs and evaluate possible factors that influence their perceptions as regards NPI importance in personal and public health protection. Results: Overall, Greeks considered NPIs important for health protection. The participants who were less likely to consider NPIs important were men (OR versus females=1.64, 95% CI:1.15 to 2.36, p=0.007), people younger than 40 years old (OR between ages over 40 versus ages below 40=0.48, 95% CI:0.34 to 0.68, p<0.001), and people who did not chose the Hellenic National Public Health Organization (EODY) to get informed about COVID-19 (OR of EODY versus other sources of information = 0.65, 95% CI:0.46-0.92, p= 0.014). Conclusions: This study profiled Greek people who do and do not consider NPIs important, mainly as of their demographic features. Focused communicational strategies in certain population subgroups are recommended.
