AB - %3Cp%3EThe Optimism%26ndash%3BPessimism Short Scale%26ndash%3B2 %28SOP2%29 described in this article measures the psychological disposition of optimism with two items. SOP2 is the English-language adaptation of an originally for the German language developed scale. Because an empirical validation of this English-language SOP2 was hitherto lacking%2C the aim of the present study was to assess the psychometric properties %28objectivity%2C reliability%2C validity%29 of the English-language adaptation and to investigate measurement invariance across both language versions using heterogeneous quota samples from the UK and Germany. Our results show that the English-language adaptation has satisfactory reliability coefficients and is correlated with 10 external variables in the study %28e.g.%2C self-esteem%2C Emotional Stability%2C life satisfaction%29. Moreover%2C scalar measurement invariance of the scale holds when comparing the UK and Germany%2C implying the comparability of latent %28co%29variances and latent means across the two nations. As an ultra-short scale with a completion time of %26lt%3B%26nbsp%3B20 s%2C SOP2 lends itself particularly to the assessment of dispositional optimism in survey contexts in which assessment time or questionnaire space are limited. It can be applied in a variety of research disciplines%2C such as psychology%2C sociology%2C or economics.%3C%2Fp%3E
