“…The deletion of item 4 in the assessment of item characteristics and reliability yielded an increase in the SDSCA-G sum scale’s alpha coefficient. Similar results were found in other studies, which also evaluated the psychometric properties of a translated version of the SDSCA [ 29 - 32 ]. Even if our reliability coefficient of the SDSCA-G sum score was comparable to findings reported by other colleagues [ 7 , 19 , 29 , 32 , 33 ], it only just reached an acceptable value.…”

BackgroundOne of the most widely used self-reporting tools assessing diabetes self-management in English is the Summary of Diabetes Self-Care Activities (SDSCA) measure. To date there is no psychometric validated instrument in German to assess self-management in patients with diabetes mellitus. Therefore, this study aimed to translate the SDSCA into German and examine its psychometric properties.MethodsThe English version of the SDSCA was translated into German following the guidelines for cultural adaptation. The German version of the SDSCA (SDSCA-G) was administered to a random sample of 315 patients with diabetes mellitus type 2. Reliability was analyzed using Cronbach’s alpha coefficient and item characteristics were assessed. Exploratory and confirmatory factor analysis (EFA and CFA) were carried out to explore the construct validity. A multivariable linear regression model was used to identify the influence of predictor variables on the SDSCA-G sum score.ResultsThe Cronbach’s alpha for the SDSCA-G (all items) was α = 0.618 and an acceptable correlation between the SDSCA-G and Self-management Diabetes Mellitus-Questionnaire (SDQ) (ρ = 0.664) was identified. The EFA suggested a four factor construct as did the postulated model. The CFA showed the goodness of fit of the SDSCA-G. However, item 4 was found to be problematic regarding the analysis of psychometric properties. The omission of item 4 yielded an increase in Cronbach’s alpha (α = 0.631) and improvements of the factor structure and model fit. No statistically significant influences of predictor variables on the SDSCA-G sum score were observed.ConclusionThe revised German version of the SDSCA (SDSCA-G) is a reliable and valid tool assessing self-management in adults with type 2 diabetes in Germany.Electronic supplementary materialThe online version of this article (doi:10.1186/s12955-014-0185-1) contains supplementary material, which is available to authorized users.

“…Higher scores on the SDSCA referred to better self-care behaviors. Cronbach's alpha was .68 in a Chinese study (Yin, Savage, Toobert, Wei, & Whitmer, 2008) and .69 in a Korean study (Choi et al, 2011). In the current study, the Cronbach's alpha was .42, and the item-total correlation was between .3 and .9.…”

“…Correlations with other measures of diet and exercise generally supported the validity of the SDSCA subscales (mean = 0.23) [18,19]. Many translations of the SDSCA have been validated such as Spanish [4], German [20], Arabic [21], Turkish [22], Korean [23] including Malay [24]. The validated SDSCA in malay version by Bujang et al (2016), reported that the cronbach's alpha for the main domains based on the fieldwork were between 0.651 and 0.905 [24].…”

Background: This study was initiated to examine the psychometric components of the Diabetes Empowerment Scale (DES) by translating and validating the scale into the Malay language (DES-M) which is the main language spoken in Malaysia. This study can determine the level of empowerment among diabetic patients towards diabetes management. In addition, the reliability and validity of the DES-M was also demonstrated. Methods: A total of 151 patients with type 2 diabetes mellitus were recruited (between June 2016 and October 2016) to complete sets of questionnaires, which were DES-M, the Malay versions of the Diabetes Quality of Life (DQOL) for Adults and Summary of Diabetes Self Care Activities Questionnaire (SDSCA). Confirmatory and Exploratory factor analysis (CFA and EFA) were carried out to determine the factor structures of the DES-M. Results: There were 100 males and 51 females with ages ranging from 19 to 81 years old (55 ± 13) included in this study. The instrument displayed good internal consistency (Cronbach's α =0.920) and the respective coefficients ranged from 0.65-0.84. Discriminant validity showed adequate correlations ranged from 0.257-0.744. Concurrent validity with SDSCA (Pearson's correlation = 0.313, p = 0.012). Predictive validity with DQOL (B = 0.27, p = 0.016). CFA indicated that four factor model of the DES-M has good fit to the data. Conclusion: This study indicates that the DES-M has a good internal consistency and validity. Therefore, it is a valid and reliable instrument for assessing empowerment score among patients with diabetes in Malaysia. Trial registration: NMRR-16-805-30503 (IIR).
