From September 19 to October 5, 2025, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey "Omnibus", to which, on its own initiative, added a monitoring question about the perception the policy of Europe and the USA regarding Ukraine. By the method oftelephone interviews (computer-assistedtelephoneinterviews, CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting) in all regions of Ukraine (the territory controlled by the Government of Ukraine), 1,008 respondents were surveyed. The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived in the territory of Ukraine controlled by the Government of Ukraine. The sample did not include residents of territories temporarily not controlled by the Ukrainian authorities (at the same time, some of the respondents are IDPs who moved from the occupied territories), and the survey was not conducted with citizens who left abroad after February 24, 2022.

Formally, under normal circumstances, the statistical error of a sample of 1008 respondents (with a probability of 0.95 and taking into account the design effect of 1.3) does not exceed 4.1%. In order to avoid the effect of the order of questions, we asked half of the respondents questions about Europe, and half of the respondents about the USA. Thus, 487 respondents answered the question about European politics, and 521 respondents answered the question about USA politics, which gives an error (with a probability of 0.95 and taking into account the design effect of 1.3) of no more than 5.8%.

Under conditions of war, in addition to the specified formal error, a certain systematic deviation is added. Factors that may affect the quality of results in "wartime" conditions were previously cited by KIIS.

In general, we believe that the obtained results are still highly representative and allow for a fairly reliable analysis of the public moods of the population.
