Reviewer 2 Report
The sentence "In 1981, Matthias Jerusalem and Ralf Schwarzer established the General Self-Efficacy (GSE) scale and validated in many countries with different patient groups." requires quoting a source from References.
What do you mean with the sentence "In addition, Korean immigrants in the United States age faster than other ethnic 65 groups"?
Revise the sentences to avoid repetition "Each item contains four possible responses. There are four possible responses:"
The sentence "This study was guided by Orem's nursing theory on self-care deficits (SCDNT)." requires quoting a source from References.
The sentence "The SCDNT of Orem has been used extensively to provide clinical guidelines for effective self-care." requires quoting some sources for the use of the SCDNT in clinical practice.
In Table 2, Cronbach's alpha for the factor Confidence (α = .54) was too loo to be used this factor. The sentence "The Cronbach's alpha for the General Self-Efficacy scale as a whole is .81, while the coping and confidence subscales have alphas of .83 and .54, respectively" also requires additional information why you have chosen to use a scale with so low internal consistence coefficient. In Table 5, you report some correlational coefficients between confidence and other variables, but the scale Confidence should not be used because of its low internal consistency. You state correctly in Discussion part "The Cronbach’s alpha of confidence is lower than .70, so it is recommended to use the entire GSE scale-Korean version or to use only the subscale coping." Why then later in Discussion you state about confidence that "However, the correlation highlights that the positive relationship between years in the US and the two subscales of confidence and coping may be meaningful."?
Why do you report the internal consistency coefficient of the total score on self-efficacy scale in your sample in the Discussion part, not in the Results part?
You state in Discussion part "The results indicate that the GSE is structurally valid and reliable for diabetic Korean immigrants." However, the internal consistency coefficient of the sub-scale Confidence is too low.
Why do you repeat in the text the same information as in Table 4? ("Through conducting the CFA, it was discovered that Model A, a one-factor model 194 did not demonstrate satisfactory goodness-of-fit based on the data (χ2 (35) = 389.98, p < 195 .01), χ2/df ratio = 11.14, AGFI = 0.64, GFI = 0.77, ECVI = 2.53, CFI = 0.68, IFI = 0.69, and 196 RMSEA = 0.244. On the other hand, the two-factor model, Model B, showed better good-197 ness-of-fit to the data (χ2 (34) = 77.57, p < .01), χ2/df ratio = 2.28, AGFI = 0.88, GFI = 0.93, 198 ECVI = 0.70, CFI = 0.91, IFI = 0.91, and RMSEA = 0.087. See Table 4.") Then, this Table 4 is redundant. Avoid repeating the same information twice! You may keep Table 4 and just comment it without repeating in text the information from this table.
Please, explain what it means when you state "According to the correlation matrix, the older aged participants are ... lower coping (r = -.168, p < .05; see Table 5)" What does lower coping mean? Unsuccessful coping? Non-effective coping? Anything else?
Introduction does not report any previous results regarding self-efficacy in people with diabetes. See, for example
