In order to assess the validity of the SHAPE scale’s structure, we conducted a Confirmatory Factor Analysis
(CFA). This statistical procedure allowed us to confirm the dimensionality of our proposed factor model. The
solution had two factors, see again Table 2. The results of the model fit assessment indicated a sub-optimal fit, as
evidenced by the Root Mean Square Error of Approximation (RMSEA) value of greater than 0.1, a Comparative
Fit Index (CFI) of 0.93, and a Standardized Root Mean Square Residual (SRMR) of 0.08. Detailed examination of
the data revealed high correlations between two items in the Agency factor (items I12 and I13). Also, item I13 was
identified as dissimilar due to its wording and was removed to improve the coherence of the SHAPE construct.
We conducted another CFA using the reduced set of items. The confirmatory factor analysis revealed an
RMSEA of 0.08, which falls within the acceptable range. Additionally, the CFI was calculated to be 0.97 and the
