The clinical assessment of the high risk suicidal person continues to be a major challenge for diagnosticians. Based on the parameter of time as a major differentiating variable, a semiprojective psychological technique–the Time Questionnaire(TQ)–has been developed. The present study reports findings elaborating & extending a pilot study using the TQ. The TQ consistently & significantly differentiates suicidal high risk patients from such clinical comparison groups as low risk & nonsuicidal.
