The psychopathology of everyday art: a quantitative Study - World ...

(including schizophrenics) against controls (56). Both studies are equally well controlled,
but study 38 used very small numbers and is therefore open to type 2 error, the authors
qualitatively note that schizophrenics' pictures frequently show less balance and
symmetry, although this did not show statistically. This review therefore accepts the
results from study 56. Depression was distinguished from controls on organisation (75),
but not by study 21, which distinguished controls, organics and mania amongst 2 other
patient groups (depression and schizophrenia) (21). The findings of no significance
between schizophrenia and other patients, and mixed patients against controls tends to
support both results (21, 75) by suggesting overlaps between certain groups (especially
depression, schizophrenia and controls) and reduces the chance of the confusion between
a diagnostic and a patient effect. Study 3 noted but did not test less compositional and
general integration in pictures by patients with personality disorder than controls, and
study 36 used a composite variable organisation, encompassing its derivatives listed in
this table, which distinguished patients with Alzheimer's disease from controls.
Summary: The composition category is generally non discriminatory for schizophrenia
although there are indications of lack of balanced work. The most discriminable diagnosis
was Alzheimer's or brain damage on central variables and organisational, particularly
integration for brain damage. Depression also distinguished integration, but there were
indications depressed scores might overlap with schizophrenia.
