A multiple choice sentence completion test, consisting of 100 items, was constructed as an indicator of differences in adjustment in comparisons of Schizophrenic, Neurotic and Control groups. Hie test was administered to veterans in three Veterans Administration neuropsychiatrie hospitals, one mental hygiene clinic and to a control group consisting of members of a service organization. Total responses for each group were converted into percentages and significance of differences determined within seven different areas of adjustment. Consistent trends in test results suggest that the Schizophrenic group differed most markedly from the Control group in the area of family and social adjustment. Responses of the Neurotic group resembled the pattern of the Control group more nearly than that of the Schizophrenic group, but tended to approxi mate the latter group in the psycho sexual area. The least deviation in a comparison of all groups occurred in the area of health adjust ment. Further studies are indicated using more rigid control of additional variables. A test of this type appears promising as a screening or diagnostic tool if subjected to further refinement and standardisât ion.

If one could observe a number of individuals during the period in which they are in the process of developing their behavioral symptoms, one might be able to discover which factors in their experience were contributing to their present behavior and to what degree. Unfortunately in clinical practice today, this is hardly feasible. When the patient has reached the point where he requires assistance in solving his problems, his Symptoms have usually developed to such an advanced stage that the clinician is obliged to judge from certain inferences he can make concerning his present behavior as to just what the salient factors are in the etiology of his disturbance. The assumption underlying the general research program, of which the present study is a part, is that the information concerning cfor- namics can be clarified by making comparative observations under standard testing conditions of patients classified into different
