Means and Discrepancies of Each Domain of the SPPC/PRS Within Statuses Defined using LTA across Three Time Points
| Status | Low Competence/ Social PIB | Variable Competence/Low PIB | High Competence/Low PIB | Variable Competence/Social PIB |
|---|---|---|---|---|
| SPPC Subscales | ||||
| Scholastic | 2.34 | 2.27 | 2.99 | 3.16 |
| Social | 2.28 | 3.18 | 3.41 | 2.57 |
| Behavioral | 2.72 | 2.41 | 3.31 | 3.14 |
| PRS Subscales | ||||
| Scholastic | 2.10 | 2.27 | 2.99 | 3.25 |
| Social | 2.14 | 3.42 | 3.47 | 1.97 |
| Behavioral | 2.51 | 2.50 | 3.37 | 3.16 |
| Discrepancy (SPPC – PRS) | ||||
| Scholastic | 0.24 | 0 | 0 | −0.09 |
| Social | 0.54 | −0.24 | −0.06 | 0.6 |
| Behavioral | 0.21 | −0.09 | −0.06 | −0.02 |
Note. LTA = latent transition analysis; PIB = positive illusory bias; PRS = Parent Rating Scale; SPPC = Self-Perception Profile for Children. Discrepancies were calculated by subtracting mean parent score from mean adolescent score within each domain on the SPPC/PRS. Positive discrepancies indicate youth overestimation, whereas negative discrepancies indicate youth underestimation relative to parents. Means and discrepancies are identical across all three time points as item-response probabilities were constrained to be equal in the LTA.
