The article presents a note on an experimental scoring system for the inside test. The author several years ago, wherein the subject's productions were scored as to interpretation, approach, solution and effect, presented an experimental scoring system for Sargent's Insight Test. Reliabilities as high as being shown, the present study was done in order to investigate validity. Two groups of 30 subjects each were given the test in the usual written form. The experimental group consisted of hospitalized mental patients, with diagnoses in neurotic or psychotic categories; the comparison group, applicants for attendant positions in a different mental hospital. All such applicants were being routinely screened by the hospital with interviews and some projective testing. The obtained results show no differences significant at the 5% level or better.
