Abstract

This study aims to investigate the psychometric properties, stability, and predictive validity of the PG-13-K. Two subsamples were used: the first subsample (N = 153), participated at Time 1 only, and the second subsample (N = 184) participated at both Time 1 and Time 2. At each time point, reliability, test-retest reliability, and validity were adequate, and the hypothesized two-factor model indicated good to excellent fit. Moreover, the PG-13-K was able to predict the correlation between prolonged grief disorder (PGD) and negative psychological factors. The PG-13-K is a useful and valid instrument for measuring PGD symptoms in Korean settings.

摘要

本研究旨在调查 PG-13-K 的心理测量特性、稳定性和预测有效性。使用了两个子样本：第一个子样本（N  = 153），仅参与时间 1，第二个子样本（N  = 184）参与时间 1 和时间 2。在每个时间点，可靠性、重测可靠性、和有效性是足够的，并且假设的双因素模型表明从良好到极好的拟合。此外，PG-13-K 能够预测长期悲伤障碍 (PGD) 与消极心理因素之间的相关性。PG-13-K 是一种有用且有效的仪器，用于在韩国环境中测量 PGD 症状。
