在精神病前驱症状中，阈下阳性症状通常先于阴性症状。表现出这些减弱的症状的个体主要是处于发展为精神障碍的临床高风险（HAD）的青少年和年轻成年人。在精神分裂症状态下，阴性症状高度预示着向可诊断疾病的转变，因此对这些症状的评估非常重要。现有的量表用于评估这一关键人群的阴性症状是信息丰富的，但有概念和心理测量的局限性和/或没有根据2005年NIMH阴性症状共识会议中描述的现代概念设计。目前的研究报告了阴性症状前驱访谈（PINS）的发展-根据共识会议建议设计的下一代量表。关于PINS的心理测量特性的初步数据被报告为正在进行的量表开发的一部分，该量表开发将使用数据驱动的迭代过程来生成最终量表。对53例患者（其中30例在12个月时进行了重新评估）的数据分析表明，PINS的beta版本具有良好的内部一致性、评分者间信度、收敛效度和判别效度。这些初步研究结果为修订这一措施提供了方向，从而产生了PINS-2，这是一种有前途的新措施，可用于评估非传染性疾病人群的阴性症状。这份手稿提出了初始规模和由此产生的未经测试的仪器，以及一系列的计划和建议，为未来的发展。
In the psychosis prodrome, sub-threshold positive symptoms are often preceded by negative symptoms. Individuals exhibiting these attenuated symptoms are primarily adolescents and young adults at clinical high-risk (CHR) for developing a psychotic disorder. In the CHR state, negative symptoms are highly predictive of the transition to diagnosable illness, making the assessment of these symptoms very important. Existing scales used to evaluate negative symptoms in this critical population are informative but have conceptual and psychometric limitations and/or were not designed according to modern conceptions delineated in the 2005 NIMH Negative Symptom Consensus Conference. The current study reports the development of the Prodromal Interview of Negative Symptoms (PINS) – a next-generation scale designed in accordance with the consensus conference recommendations. Preliminary data on the psychometric properties of the PINS is reported as part of ongoing scale development that will use a data-driven, iterative process to generate a final scale. Analysis of data from 53 CHR cases, 30 of whom were re-evaluated at 12-months, indicated that the beta version of the PINS demonstrated good internal consistency, inter-rater reliability, convergent validity, and discriminant validity. These preliminary findings provide direction for a revision of this measure, which resulted in the PINS-2, a promising new measure for the assessment of negative symptoms in CHR populations. This manuscript presents both the initial scale and resulting untested instrument, as well as a series of plans and recommendations for future development.
