The interrater reliabilities of the 12 scales of the Psychotic Inpatient Profile (PIP) were assessed in three independent samples. These reliabilities were found to be consistently low for the three samples. Several possible sources of low reliability were investigated, and evidence to support the hypothesis that consistent rater biases might have contributed to this low reliability was found. The authors make several suggestions of ways to improve PIP's reliability.
在三个独立样本中评估了精神病住院患者概况（PIP）12个量表的评分者间信度。发现这三个样本的这些信度一直很低。研究了几个可能导致信度低的原因，并找到了支持一致的评分者偏差可能导致这种低信度这一假设的证据。作者提出了几种提高PIP信度的方法建议。
