Two-sided t-tests for independent samples: OPD-2-LSIA, Levels of Structural Integration Axis of the Operationalized Psychodynamic Diagnosis System; F20, schizophrenia; F25, schizoaffective disorder; N, number; M, mean; SD, standard deviation.

bold = significance maintained after Bonferroni-Holm method.

OPD-2-LSIA values: 1 – High level of structural integration, 1.5 – High to moderate level of structural integration, 2 – Moderate level of structural integration, 2.5 – Moderate to low level of structural integration, 3 – Low level of structural integration, 3.5 – Low to disintegrated level of structure, 4 – Disintegrated level of structure.
