Abstract: o decrease the burden of diabetes in society, early screening of undiagnosed diabetes and prediabetes is needed. Integrating a diabetes risk score into a mobile app would provide a useful platform to enable people to self-assess their risk of diabetes with ease. he objectives of this study were to (1) assess the profile of Diabetes Risk Score mobile app users, (2) determine the optimal cutoff value of the Finnish Diabetes Risk Score to identify undiagnosed diabetes and prediabetes in the Chinese population, (3) estimate users’ chance of developing diabetes within 2 years of using the app, and (4) investigate high-risk app users’ lifestyle behavior changes after ascertaining their risk level from the app. e conducted this 2-phase study among adults via mobile app and online survey from August 2014 to December 2016. Phase 1 adopted a cross-sectional design, with a descriptive analysis of the app users’ profile. We used a Cohen kappa score to show the agreement between the risk level (as shown in the app) and glycated hemoglobin test results. We used sensitivity, specificity, and area under the curve to determine the optimal cutoff value of the diabetes risk score in this population. Phase 2 was a prospective cohort study. We used a logistic regression model to estimate the chance of developing diabetes after using the app. Paired t tests compared high-risk app users’ lifestyle changes. total of 13,289 people used the app in phase 1a. After data cleaning, we considered 4549 of these as valid data. Most users were male, and 1811 (39.81%) had tertiary education or above. Among them, 188 (10.4%) users agreed to attend the health assessment in phase 1b. We recommend the optimal value of the diabetes risk score for identifying persons with undiagnosed diabetes and prediabetes to be 9, with an area under the receiver operating characteristic curve of 0.67 (95% CI 0.60-0.74), sensitivity of 0.70 (95% CI 0.58-0.80), and specificity of 0.57 (95% CI 0.47-0.66). At the 2-year follow-up, people in the high-risk group had a higher chance of developing diabetes (odds ratio 4.59, P=.048) than the low-risk group. The high-risk app users improved their daily intake of vegetables (baseline: mean 0.76, SD 0.43 follow-up: mean 0.93, SD 0.26 t81=–3.77, P .001) and daily exercise (baseline: mean 0.40, SD 0.49 follow-up: mean 0.54, SD 0.50 t81=–2.08, P=.04). he Diabetes Risk Score app has been shown to be a feasible and reliable tool to identify persons with undiagnosed diabetes and prediabetes and to predict diabetes incidence in 2 years. The app can also encourage high-risk people to modify dietary habits and reduce sedentary lifestyle.

Abstract: This study translated the reaction to impairment and disability inventory (RIDI) to Chinese and validated it for use in Hong Kong. We conducted an instrument validation of the Chinese RIDI, with a s le of 244 persons with CID. The research questionnaire collected demographic information, illness-related variables, the Chinese version of RIDI (C-RIDI), and measures of resilience and well-being. We examined the factor structure, internal consistency, convergent validity, and criterion-related validity of the C-RIDI. The C-RIDI has good content validity and no major changes to the translated items were needed for the use in Hong Kong. For factor structure, we replicated the results of Livneh et al. The C-RIDI has two second-order factors of adaptive and nonadaptive scales, which interact with the two denial subscales. Internal consistency of the subscales is satisfactory except for the three-item denial subscales. Correlations of the C-RIDI subscales with illness-related variables, resilience, and mental well-being are consistent with our hypotheses and provide support for the convergent and criterion-related validity of the scale. The C-RIDI has satisfactory psychometric properties. The study results support its internal consistency, convergent validity, criterion-related validity, and factorial validity.IMPLICATIONS FOR REHABILITATIONEmotional adjustment to chronic illness and disability is a key determinant of illness self-management, mental well-being, and quality of life.The study translated the reaction to impairment and disability inventory into Chinese and conducted a psychometric evaluation of the translated instrument.The Chinese RIDI had a similar second-order factor structure as in the validation studies of the English version, and result of this confirmatory factor analysis support the theory underlying the design of the RIDI.The Chinese RIDI had satisfactory convergent and criterion-related validity and internal consistency, and is ready for application in rehabilitation practice and research in the Chinese context.

Abstract: To test whether health literacy is associated with sunlight exposure behavior, we interviewed 648 Chinese adults aged 65 years or older. Using the information-motivation-behavioral skills model and structural equation modeling, we tested whether health literacy was associated with the complex relationships among knowledge about vitamin D, attitudes toward sunlight exposure, doctor recommendations regarding sunlight exposure, and sunlight exposure behavior. Health literacy was directly associated with sunlight exposure (β=.20, p<.01). Indirect relationships also existed between knowledge and sunlight exposure through health literacy (β=.46, p<.001) and between attitudes and sunlight exposure through health literacy (β=-.12, p<.05). The model had good fit (χ(2)/df=2.79 RMSEA=.053, p=.346 CFI=.95 TLI=.92). Health literacy should be considered when educating older adults about vitamin D supplements and sunlight exposure. Providing relevant knowledge or making doctor recommendations might not be effective. Training should focus on in iduals with low health literacy who may be less likely to receive sunlight exposure.

Abstract: This study identified the profiles of subgroups of type 2 diabetic (T2DM) patients of the Patient Empowerment Programme (PEP) by different levels of benefits gained in diabetic self-management behaviors, self-efficacy, and health literacy. This study adopted a non-experimental repeated-measures design on T2DM patients who joined PEP, using structured questionnaires. Latent profile analysis (LPA) was used to identify patterns of participants' change on the outcome measures. Findings of LPA revealed that participants who were older, unemployed, weaker in diabetic self-management, and having a higher self-perception in personal disease risk were more likely to join the empowerment sessions and gained more benefits from the program. Participants with lower impairment in energy function and lower autonomy in personal health care showed more improvement in the outcomes. The study identified significant factors associated with patients' participation on and benefits gained from a service delivery model integrating health education and patient empowerment in a primary care setting. Findings from this study shed light on strategies to improve the PEP design in order to meet the needs of in iduals with different health-related profiles.

Abstract: The mechanisms underlying the relations among health literacy, perceived capacity for communication, diabetes knowledge, and diabetes self-care are unclear. This study tested this relation using structural equation modeling with a s le of 137 Chinese patients 65 years of age or older with type 2 diabetes. The model showed that health literacy, knowledge, communication capacity, and diabetes self-care formed complex relations. After adjusting for age, education, and Chinese cultural influence, health literacy affected diabetes self-care indirectly through perceived capacity for communication (standardized estimate coefficient=.641, p<.001) but not diabetes knowledge. To enhance self-care, interventions should be tailored to increase patient health literacy and perceived capacity for communication with health care providers. Training should be provided to patients to enhance their communication abilities.

Abstract: To develop and to test the psychometric properties of the Chinese Health Literacy Scale for Diabetes. Patients with diabetes encounter many challenges when making health decisions in their daily lives, as they have access to many different kinds of health information. Health literacy issues are new topics in Chinese society. Without a valid and reliable instrument in Chinese, it is difficult to measure the level of health literacy and promote the concept of health literacy in Chinese societies. A methodological study with a s le of 137 patients with type 2 diabetes aged 65 years or older. Chinese Health Literacy Scale for Diabetes was developed with reference to the revised Bloom's taxonomy model. Psychometric tests (content validity, item analysis, construct validity, discriminative ability and test-retest reliability) were conducted. Correlations between Chinese Health Literacy Scale for Diabetes and four relevant measures were tested. Cronbach's alpha and alpha if item deleted were calculated to assess internal consistency. Cronbach's alpha for Chinese Health Literacy Scale for Diabetes and its four subscales (remembering, understanding, applying and analysing) were 0·884, 0·885, 0·667, 0·654 and 0·717, respectively. The Chinese Health Literacy Scale for Diabetes was significantly correlated with the Diabetic Knowledge Scale (r = 0·398, p < 0·001), the Diabetic Management Self-Efficacy Scale (r = 0·257, p < 0·001), the Preschool and Primary Chinese Literacy Scale (r = 0·822, p < 0·001) and the Chinese Value of Learning Scale (r = 0·303, p < 0·001). It took an average of seven minutes to complete this 34-item instrument. The findings of this study support the Chinese Health Literacy Scale for Diabetes as a reliable and valid instrument for measuring the health literacy of Chinese patients with diabetes. We recommend that clinicians use this tool to assess patients' health literacy before conducting any kind of health promotion.
