• Psychological Burden in Relapsing-Remitting Multiple Sclerosis: Sociodemographic and Clinical Determinants of Persistent Anxiety and Depression over a Six-Month Follow-Up (2026) · Nursing Reports · cited 1× · doi

  The sample size was limited to 35 participants due to logistical and time constraints. The study utilized a convenience sampling method, which may not be representative of the entire population. The study was conducted over a relatively short period of six months, which may not capture long-term effects. The study did not include a control group for comparison.

  The study faced logistical and time constraints, resulting in a limited sample size of 35 participants. The operational limitations of the healthcare service during the pilot phase affected the study. The small sample size and distribution of variables required the use of non-parametric and parametric tests.

  The investigation has a limited sample size, with only 90 subjects selected. The subjects were selected from a specific geographic area, which may limit the generalizability of the results. The investigation only considered adolescent subjects, which may limit the applicability of the results to other age groups.

  Therefore, results should be interpreted with caution, and future studies should consider employing rigorous sample size estimation techniques to enhance the robustness of the findings. The limitations of this study include being a secondary data analysis and its cross- sectional design, which restrict causal inference and generalizability.
