OPTIMIZING GHANAIAN POSTGRADUATE STUDENTS’ JOB PERFORMANCE:

THE IMPACT OF POLYCHRONICITY, WORK-SCHOOL FACILITATION, AND

ORGANISATIONAL SUPPORT

Dear Authors,

I have the opportunity to review this interesting article. Apart from its many advantages, several things need to be enriched and added to make it more perfect as a scientific work, among others:

Introduction

Add research gaps between variables.

Literature Review

• Add sufficient narrative or explanation of the conceptual framework.

• According to the conceptual framework, add a hypothesis about the relationship between Work School Facilitation and job performance.

Methodology

Add references and test for common method bias (CMB) adequately. As a guidances/references, see the link: https://doi.org/10.3390/educsci14040384; https://doi.org/10.3390/jintelligence10030044.

Results

• Add a Results section with the order of presentation: Description and Correlation Analysis (Mean, Standard Deviation, and Correlation Coefficient of Variables); Measurement Model; Structural model; Fit Model; and Slope Analysis.

• Hypothesis test results should be interpreted adequately, including the addition of new hypotheses (Work School Facilitation with Job Performance).

Discussion of Hypotheses

• This section should be changed to just “Discussion.”

• Add an analysis of the relationship between Work School Facilitation and job performance.

• The discussion for each hypothesis should be sharpened and analyzed more critically, compared with previous research and research gaps.

Suggestions for future studies

In this section, change it to "Limitation and Future Research." Add limitations to this study and relate them to Future Research.

Conclusion

Add a conclusion section containing the main research findings. Show originality as a novelty. Complete the theoretical contribution and novelty of the findings.

Additional Editor Comments:

Several key issues impact the validity, reliability, and results of this study. The use of convenience sampling introduces bias, which may limit the generalizability of the findings and affecting external validity. Please justify the use of convenience sampling and highlight practical constraints. Additionally, the sample size of 341 is based on Krejcie and Morgan’s formula, but the lack of a clear justification for its appropriateness raises concerns about reliability. Please justify the appropriateness of the sample size by explaining why the use of Krejcie and Morgan's formula is suitable for this particular study. The Harman’s single-factor test reveals common method bias with a variance of 44.13%, which is below the recommended threshold, potentially distorting relationships between variables and affecting internal validity. What measures did you use to reduce such bias. Finally, retaining weak indicators with factor loadings below 0.4 compromises construct validity and reliability. Please explain why specific indicators (e.g., OS6) were kept despite lower factor loadings.

ORGANISATIONAL SUPPORT

Dear Authors,

I really appreciate your hard work in fulfilling my comments. Many thanks for it. However, several parts of the article still need improvement. Some of them which are quite crucial are:

The description of CMB is in the Methodology and Results Section—merge them into one. The citation source regarding CMB that you added does not explain CMB at all, so it would be better if you use the article references with the following links: https://doi.org/10.3390/educsci14040384; https://doi.org/10.3390/jintelligence10030044. In addition, it would also be better if you added a description of what CMB is, its urgency, and how to overcome it. Both articles can be used as references.

In Table 7, sort H1 – H5. Hypothesis test results should be interpreted adequately. What do these results mean? All path coefficient values are positive; what does that mean? Also, explain which result is the largest and what its consequences are. Then, it also shows the smallest result along with its consequences.

Additional Editor Comments:

This manuscript requires extensive editing to improve the clarity, accuracy, and consistency of English language usage, grammar, and academic style. Additionally, the research gap and significance of the study are not clearly articulated, making it difficult to understand how this work advances existing knowledge. The discussion section also needs substantial revision to present a balanced and critical debate, integrating the study's findings with both supporting and contradictory evidence from the current literature. At present, the discussion lacks depth, critical reflection, and fails to provide meaningful insights into the implications of the results.

Reviewer #4: Dear author,

Thank you for the opportunity to review this manuscript. Below are the comments on my review:

1. The subject matter of the article is relevant to be published in the journal.

2. The title clearly reflects the subject matter of the article.

3. The abstract and keywords do not provide good information about the article. It is not clear what the main objective of the research is.

4. Check whether all authors cited in the article are in the manuscript's references, and vice versa.

5. The article has problems with clarity and coherence in its language, which need to be reviewed. The Introduction does not make it clear what the objective of the research is, and what the research question (or questions) to be answered in the study are.

6. There is articulation between the theme and the theoretical basis. There is a good dialogue with the scientific literature in the field of knowledge.

7. There is analysis of the data and coherence in the argument. The data were categorized, organized, and analyzed in light of the theory that underpinned the research.

8. The bibliography used in the article is adequate and up-to-date.

This is an interesting study. However, I hope that these comments will help improve your manuscript.

Reviewer #5: Corrections given by the referees for the research were made. However, there are some things that need to be done in order to provide a more solid foundation for the research.

1. For reliability, McDonald Omega can be given in addition to Cronbach Alpha.

2.Tolerance and CI can be given for the multicollinearity problem.

3. It would be nice if a few more values such as RMSEA, CFI are given as model fit indexes.

4. Calculating the effect size of the study would be good for understanding the results reached in the findings.

6. Limitations related to the sampling method should be mentioned.

Reviewer #6: The authors are commended for the significant improvements made to the manuscript, particularly in response to previous feedback concerning the introduction, conceptual framework narrative, methodological details (sample justification, measurement specifics, CMB analysis), and the robustness of the results presentation and discussion. The inclusion and testing of new hypotheses (H4 and H5) have notably enriched the study's scope.

This study investigates the impact of polychronicity, work-school facilitation, and organizational support on the job performance of Ghanaian postgraduate students, grounded in the Conservation of Resources (COR) theory. The quantitative, explanatory design, employing a three-wave survey with 341 distance education postgraduate students to minimize common method bias, and the use of Structural Equation Modeling (SEM) with SMART PLS, are appropriate methodological choices.

The manuscript presents original research supported by a technically sound research design. The sample size justification, based on Krejcie and Morgan (1970), the use of validated scales (with clearly stated sources and item counts), and the application of PLS-SEM are all appropriate. The data analysis, encompassing common method bias (CMB) checks via time-lagged data collection, Harman's single-factor test, and correlation matrix (all strengthened in Rev 3), measurement model validation (factor loadings, Cronbach's Alpha, CR, rho_A, AVE, HTMT – detailed in Tables 3 & 4), and structural model assessment (VIF, R-squared, path coefficients, T-statistics, P-values, F-squared, model fit indices – presented in Tables 5-8), has been conducted rigorously and is well-reported. The conclusions drawn are generally supported by the presented data, which is made available according to PLOS ONE policy.

The manuscript is well-organized and presented intelligibly in standard English. While generally clear, a final light proofread to address minor grammatical points or awkward phrasing would further enhance its readability prior to publication.

In conclusion, this manuscript describes a technically sound piece of research with relevant findings. Provided the authors can definitively address and clarify the ethics statement to meet PLOS ONE's requirements, the manuscript will be very close to being acceptable for publication.
