The UCLA Loneliness Scale (ULS-20) and its short version (ULS-8) are widely used to measure loneliness. However, the question remains whether or not previous studies using the scale to measure loneliness are measuring the construct equally across countries. The present study examined the measurement invariance (MI) of both scales in Germany, Indonesia, and the United States ( N = 2350). The one-, two-, and three-factor structure of the ULS-20 did not meet the model fit cut-off criteria in the total sample. The ULS-8 met the model fit cut-off criteria and has configural, but not metric invariance because two items unrelated to social isolation were not MI. The final six items (ULS-6) exclusively related to social isolation had complete MI. Participants from the United States scored highest in the ULS-6, followed by participants from Germany and then Indonesia. We conclude that the ULS-6 is an appropriate measure for cross-cultural studies on loneliness.

Pandemik COVID-19 memiliki berdampak pada kesehatan, sosial, ekonomi, hingga psikologis. Salah satu dampak dari COVID-19 adalah panic buying. Artikel ini bertujuan mengulas panic buying melalui perspektif psikologi. Kami melakukan telaah literatur panic buying pada riset-riset terkini baik pada kasus pandemik COVID-19 hingga pandemik serupa yang terjadi pada puluhan tahun silam. Pada bagian awal, artikel ini membandingkan definisi panic buying dengan istilah serupa, seperti buying frenzies, impulsive buying, dan compulsive buying. Kemudian, kami mengulas penjelasan psikologis di balik panic buying  melalui perilaku konsumen, ketakutan dan kecemasan, stres, ketidakpastian, dan paparan media. Pada bagian terakhir, kami mengajukan beberapa solusi yang dapat dijadikan panduan kebijakan untuk mengatasi panic buying saat wabah pandemik terjadi.
