The De Jong Gierveld Loneliness Scale (DJGLS) has been widely used to measure two types of loneliness: social and emotional loneliness. However, no Japanese translation has been developed. Furthermore, the characteristics of social and emotional loneliness in the Japanese population remain unclear. This study examined the psychometric properties of a Japanese translation of the DJGLS.
A total of 1,000 participants (500 young and older adults each) completed online questionnaires, which included items on loneliness, depression, and social isolation.
Confirmatory factor analyses revealed a two-correlated factor structure for the Japanese translation of the DJGLS in both young and older adults. McDonald's omega coefficient was high for both social and emotional loneliness. The emotional loneliness subscale was moderately correlated with general loneliness and depression. Furthermore, the social loneliness subscale was moderately correlated with general loneliness and social isolation. Depression was more strongly correlated with emotional loneliness than with social loneliness. Item response theory demonstrated the characteristics of each item in the Japanese translation of the DJGLS.
These results support the validity and reliability of the DJGLS among young and older Japanese adults.
德容-吉尔维尔德孤独量表（DJGLS）已被广泛用于测量两种类型的孤独：社交孤独和情感孤独。然而，尚未有该量表的日语翻译版本。此外，日本人群中社交孤独和情感孤独的特征仍不明确。本研究检验了DJGLS日语翻译版本的心理测量特性。
共有1000名参与者（年龄较大和较小的成年人各500名）完成了在线问卷，问卷内容包括孤独感、抑郁和社会隔离等项目。
验证性因素分析显示，DJGLS日语翻译版本在年轻和年长成年人中均呈现出双相关因素结构。社交孤独和情感孤独的麦克唐纳ω系数均较高。情感孤独分量表与总体孤独感和抑郁呈中度相关。此外，社交孤独分量表与总体孤独感和社会隔离呈中度相关。抑郁与情感孤独的相关性强于与社交孤独的相关性。项目反应理论揭示了DJGLS日语翻译版本中各项目的特征。
这些结果支持DJGLS在日本年轻和年长成年人中的有效性和可靠性。
