A new 15-item version of the positive subscale of Community Assessment of Psychic Experiences (CAPE-P15) has been recently proposed and used to measure psychotic-like experiences. The wide application of this scale is thought to be feasible and cost-effective, due to its manageable length and higher level of internal consistency. However, its psychometric properties have not been well established.
The validity and reliability of the CAPE-P15 were assessed in 1255 college students across two time frames (over a lifetime and in the past month). Confirmatory factor analysis was used to confirm its construct validity and measurement invariance across sex. Pearson's correlation analysis was used to investigate its clinical and concurrent validity. We also calculated the test-retest reliability and internal consistency to verify the reliability of the scale. Finally, telephone interviews were performed to explore the consistency between self-reported and interview-verified CAPE-P15 scores.
The scale has adequate psychometric properties in terms of construct, clinical and concurrent validity; measurement invariance across sex; test-retest reliability; and internal consistency. We also confirmed considerably high consistency between self-reported and interview-verified CAPE-P15 scores.
This study confirms that the CAPE-P15 is a valid and reliable instrument for assessing psychotic-like experiences in college students, both over a lifetime and in the past month. This overall assessment of the CAPE-P15 supports its more widespread use in this population. However, further research is needed to assess its utility in clinical settings, as well as in general population.
最近提出了社区心理体验评估量表（CAPE）正性量表的一个 15 项新的版本（CAPE-P15），用于测量类精神病体验。由于其可管理的长度和更高的内部一致性，该量表的广泛应用被认为是可行且具有成本效益的。然而，其心理测量特性尚未得到很好的确定。
在两个时间框架（一生中及过去一个月），对 1255 名大学生进行了 CAPE-P15 的有效性和可靠性评估。验证性因子分析用于确认其结构效度和性别之间的测量不变性。皮尔逊相关分析用于研究其临床和同期效度。我们还计算了测试-重测信度和内部一致性，以验证量表的可靠性。最后，通过电话访谈探讨了 CAPE-P15 自评得分和访谈验证得分之间的一致性。
该量表在结构、临床和同期效度、性别测量不变性、测试-重测信度和内部一致性方面具有足够的心理测量特性。我们还证实了 CAPE-P15 自评得分和访谈验证得分之间的高度一致性。
本研究证实，CAPE-P15 是评估大学生一生中及过去一个月类精神病体验的有效且可靠的工具。对 CAPE-P15 的总体评估支持其在该人群中的更广泛应用。然而，需要进一步的研究来评估其在临床环境以及一般人群中的实用性。
