Psychache has been proposed to cause suicide when it becomes unbearable. However, existing measures of psychache do not directly target unbearable psychache. Thus, the purpose of the current study was to provide initial validation for a brief measure of unbearable psychache.
Three items were selected to create the Unbearable Psychache Scale (UP3). Psychometric properties were assessed in two populations: (1) an online sample composed of 1,006 adults (53% male) from various locations in the United States and (2) a sample of 190 psychiatric inpatient adults (47% male) from a hospital in Western Canada.
In both samples, the UP3 demonstrated excellent internal reliability, and strong convergent and predictive validity. Additionally, the UP3 predicted significant variance in suicidal ideation over and above documented correlates of suicidal ideation including general psychache, hopelessness, perceived burdensomeness, and low belongingness.
The UP3 is a brief, psychometrically sound measure of unbearable psychache that may be well-suited for use in research protocols and clinical assessments.
当精神痛苦变得无法忍受时，精神痛苦被认为会导致自杀。然而，现有的精神痛苦测量方法并没有直接针对无法忍受的精神痛苦。因此，本研究的目的是为一种简短的无法忍受的精神痛苦测量方法提供初步验证。
选择了三个项目来创建无法忍受的精神痛苦量表（UP3）。在两个群体中评估了心理测量特性：（1）来自美国各地的 1006 名成年人（53%为男性）的在线样本；（2）来自加拿大西部一家医院的 190 名住院精神病患者的样本（47%为男性）。
在两个样本中，UP3 都表现出了极好的内部可靠性，以及强大的收敛和预测有效性。此外，UP3 预测了自杀意念的显著差异，超过了自杀意念的已知相关因素，包括一般精神痛苦、绝望感、感知负担和归属感低。
UP3 是一种简短、心理测量可靠的无法忍受的精神痛苦测量方法，可能非常适合用于研究方案和临床评估。
