ANICAMA GOMEZ, José et al. Psychometric evidence of the state-Trait anxiety inventory: IDARE In University Students from Lima in times of Covid-19. Psychol. av. discip. [online]. 2021, vol.15, n.2, pp.49-62.  Epub June 16, 2022. ISSN 1900-2386.  https://doi.org/10.21500/19002386.5911.

420 university students of Psychology and Law were evaluated in order to update the psychometric evidence of the State Anxiety Inventory - trait: STAI in times of the COVID-19 pandemic. The sample consisted of men and women, the group of women being the largest, with an age range between 18 to 57 years old. The validation tests with expert judges allow obtaining an Aiken “V” greater than 0.80 and the values of the binomial test were significant with a p <.05. The item-test discriminative analysis tests obtained scores for the entire Inventory ranging from 0.334 to 0.679, with item 34 eliminated for not meeting the expected criteria. For convergent validity, its correlation with the CASE A30 questionnaire obtained for A-E an “r” of .320 and for A-R of .522, both with a p <.05. The construct validity was evaluated by means of the exploratory and confirmatory factor analysis, finding 4 independent scales: state anxiety, state well-being, trait anxiety and trait well-being. Reliability was obtained by calculating Cronbach's Alpha coefficient = 0.86 and McDonald's Omega coefficient = 0.89. Likewise, in the reliability by Guttman halves, values between 0.76 and 0.89 were found. Scales were established by sex and by age for the total population. The prevalence of anxiety in university students in Lima was 29.4 %, which is close to the data from China and Colombia, but it is higher than in England all in the time of COVID-19.
