Abstract Background The Teacher Stress Inventory (TSI) is an instrument used for assessing occupational stress among teachers but has not been adapted or validated for use in Nigeria. Objective This study aimed to modify and adapt the TSI for use in Nigeria and also assess its reliability and validity. An expert panel was constituted to modify the original version of the TSI. Thereafter, both the original and the modified versions were applied to 471 teachers from 15 schools in Oyo State, Nigeria. Result Of all the respondents, 227 (48.2 %) were men and 244 (51.8 %) were women. Mean age was 36.55 ± 8.80 years. Cronbach α for all items of the modified version was .943, and item mean score was 2.60 (1.86–3.56). Concurrent validity of the modified TSI demonstrated significant correlations p< 0.001 with the corresponding items of the original version. Test-retest reliability of the modified version was .988. There were significant inter-item correlations for all the items of the modified version of the TSI. Conclusion The modified version of the TSI is a valid and reliable instrument in the Nigerian population to assess teachers’ stress.
