- Mean scores (d), standard deviations (SD), and t and p values. The d values reflect the deviations from the Dutch normative population in standard deviation units, where a positive score indicates that the adolescents with short stature judged themselves to have higher perceived competence, more anxiety, and a higher score on personality scales than the norm group, respectively.
- The d values have the following common effect sizes: a value smaller than 0.2 reflects no deviation from the norm, while values between 0.2 and 0.5, between 0.5 and 0.8, and greater than 0.8 reflect small, moderate, and large deviations, respectively [42]. T-tests examined whether norm deviation scores deviated from zero (the norm).
