The study’s reliance on self-report questionnaires introduces potential bias, and the absence of objective assessments undermines the validity of its conclusions. The small sample size (n=60) appears inadequate for the complexity of the statistical analyses (MANCOVA, SEM, HLM), raising concerns about overinterpretation. A more rigorous methodological approach is needed to enhance credibility. Addressing these issues would strengthen the study’s robustness and improve the clarity and reliability of its findings.
The concerns about self-report bias and sample size make sense. Relying only on self-reports can introduce subjectivity, so adding objective measures in future studies would strengthen the findings. Also, with a sample of just 60 participants, running complex analyses like MANCOVA, SEM, and HLM does raise questions about statistical power. Were any post-hoc power tests done to check if the sample size was actually sufficient for these methods?
