A one-way within-subjects ANOVA is the most appropriate statistical design for this study because it involves measuring the same variable (depression scores) in the same participants across four different conditions (seasons). This design allows the researcher to compare the means of the four conditions while controlling for individual differences between participants, and it also increases the statistical power of the analysis. The other options (A, B, and D) do not fit the study design as well.
