Examined the predictive validity of the Zung Index of Potential Suicide. Subjects hospitalized for a suicide attempt were followed up 6 months later. In agreement with earlier studies, the IPS clinical scale was related to suicidal ideation and prior attempting at the time of admission. However, it was not related to further suicidal behavior or ideation at the 6-month followup. It is concluded that the scale lacks predictive validity and its use for assigning suicidal risk is not justified.
研究了自杀潜在性的zung指数的预测效度。对因自杀未遂住院的患者在6个月后进行了随访。与早期研究一致，入院时IPS临床量表与自杀意念和既往自杀未遂有关。然而，在6个月的随访中，它与进一步的自杀行为或意念无关。得出的结论是，该量表缺乏预测效度，将其用于评估自杀风险是不合理的。
