The Optimism–Pessimism Short Scale–2 (SOP2): a comprehensive validation of the English-language adaptation

Abstract: The Optimism–Pessimism Short Scale–2 (SOP2) 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, the aim of the present study was to assess the psychometric properties (objectivity, reliability, validity) of the English-language adaptation and to investigate measurement invariance across both… Show more

“…The 2-item Optimism–Pessimism Short Scale–2 (SOP2) [ 51 ]/Skala Optimismus–Pessimismus–2 [ 52 ] measures dispositional optimism. SOP2 shows sufficient internal consistency (ω = .68 for the English-language version, ω = .77 for the German-language version) and evidence for factorial and construct validity [ 51 ].…”

“…A total of 16 items, from the previous study, were included in this study. In addition to the speciesism scale, BFI-2-XS personality scale, and items to assess attitudes towards specific wild animal interventions, we now also included the Animal Attitude Scale (Herzog et al, 1991) and the Optimism-Pessimism Short Scale-2 (Nießen et al, 2022). We also included the Oxford Utilitarianism Scale for exploratory purposes (Kahane et al, 2018).…”

“…The Optimism-Pessimism Short Scale-2 (SOP2) [39], measures the psychological disposition of optimism with two items rated on a seven-point Likert scale from not at all optimistic (1) to very optimistic (7) for Item 1 and from not at all pessimistic (1) to very pessimistic (7) for item 2. To obtain an optimism scale score, the negatively worded item is recorded, and the unweighted mean score of the two items is computed (e.g., The next question deals with optimism.…”

“…The primary objective of the present study was to investigate potential correlates of optimism/pessimism in a sample of patients with CKD, including socio-demographics, body appreciation and disordered eating symptoms. As a secondary objective, we proposed to examine the psychometric properties of an Arabic translation of the SOP2 [39]before its use in our sample.…”
