Reviewer #1: Kalayou K Berhe et al. performed a systemic review and meta-analysis to evaluate the effectiveness of motivational interviewing intervention on glycemic control and on depressive symptoms for patients with diabetes. This study encompasses an interesting topic, but it has some critical problems.

1. The aim of study is to reveal the effect of motivational interviewing intervention on depressive symptoms for patients with diabetes. However, author’s assessment for them are unclear. In the result section, they claimed depressive symptoms was improved by motivational interviewing intervention. Cobversely, they concluded that motivational interviewing intervention is not effective for depressive symptoms.

2. The manuscript needs to be edited.

Minor comments

1. Hgb. A1C is unusual abbreviation. Motivation interviewing should be expressed as full spelling.

2. What is the difference for NIDD and NIDDM?

3. I feel difficulty to see Table 1. Please reconsider to the structure of table1.

4. Fig2, 3; Font type should be changed as the same as the others.

5. Table 6; The font type for “Huang” is different for the others.

6. Ref 34 seems to include Chinese characteristics.

7.

Comments to the Editor

Revision 1

1. The aim of study is to reveal the effect of motivational interviewing (MI) intervention on depressive symptoms for patients with diabetes. However, author’s assessment for them is unclear (miss match between result and conclusion).

• The finding of four studies in systematic review and pooled result of meta-analysis (fixed effect model analysis) identified that there was statistically significant improvement of depressive symptoms

• But the pooled result of meta-analysis in fixed effect model analysis had heterogeneity then further subgroup analysis using random effect model was required then to get the true effect subgroup analysis according to MI session time and follow-up period was done.

•There for pooled result of subgroup analysis showed that MI intervention is not effective for depressive symptoms (means do not have significant difference in the reduction of depressive symptoms among intervention and control group)

• Then to avoid confusion results of systematic review and pooled result in fixed effect model analysis for depressive symptoms were removed.

• The pooled results of subgroup analysis rephrased in line to conclusion and in such away readers could understand as per your comment.

• Then Rephrased as “ Effect of MI intervention on depressive symptoms was identified through subgroup analysis according to intervention session time (30 or 60-80 minutes) and Follow-up period (3 or 24 months) then result showed that there was no significant difference in the reduction of depressive symptoms between the intervention and control groups. The output results were (WMD, -1.58; 95% CI, -5.05 to -0.188; p = 0.37; I2=48%), (WMD, -4.30; 95% CI, -9.32 to -0.73; p = 0.09; I2=95%) , (WMD, -4.45; 95% CI, -10.58 to 1.69; p= 0.16; I2=96%) and (WMD, -2.12; 95% CI, -5.54 to 1.30; p = 0.22; I2=83%) respectively”. page 2 and 3 (Abstract ) and page 25

2. HgbA1C is unusual abbreviation. Motivation interviewing should be expressed as full spelling.

• HgbA1C is written in usual way or expanded form as glycosylated hemoglobin A1C (HgbA1C) throughout the manuscript as per your comment and MI is also written in the expanded form as Motivation interviewing (MI) throughout the manuscript as per your comment

3. What is the difference for NIDD and NIDDM ( Search strategy section: on page 7 and 8 )

• Both are the same used to describe type 2 diabetes mellitus as none insulin dependent diabetes or diabetes mellitus and there is no difference. Those are key words or mesh terms we used to search articles for review because authors may use either of them interchangeably in their article as key word.

4. I feel difficulty to see Table 1. Please reconsider to the structure of table1.

• Table 3 (page 15& 16) font size increased or corrected to make it visible and Table 1 (Page 9) “Evaluation of the methodological quality of the reviewed studies (RCT) (6 in number) based on JBI appraisal checklist. Its column is reviewed articles name of first author (with reference number: 39,16,32,33, 34 and 43) and its raw is evaluation criteria (yes/No). Font size increased to make it visible

5. Fig2, 3; Font type should be changed as the same as the others.

• Because of the figures are analyses outputs of the software in the form of picture then copied and directly pest directly because of this could not change or modify the font style except increase its size. Therefore as the size of the picture or figure increase then font size also increased so that legible to the reader. Additionally the main important pooled result were written properly as (WMD, -0.27; 95% CI, -0.46 to -0.09; p= 0.004) and (WMD, -2.63; 95% CI, -3.45 to -1.80; p< 0.00001) respectively (Page 19 & 20). Moreover, as requirement of the journal figures are uploaded separately & individually in the form of TIFF

6.Table 6; the font type for “Huang” is different for the others.

• The font type for “Huang” which is differ for the others or made bold then corrected or made similar font type like others or avoid from making bold the word Huang (page 20 & 22).

7.Ref 34 seems to include Chinese characteristics: The Chinese character is removed (Reference section)
