Here is an excrept from a paper:
Attrition analyses performed using Chi-square tests for independence (with Yates Continuity Correction) revealed that targets of bullying at T1 had a higher probability of dropout at T2 as compared with non-targets, χ2 (1, N = 2249) = 5.43, p = .02, phi = -.05. An independent samples t-test also revealed that participants who only responded at T1 had significantly higher levels of job insecurity at T1 (M = 5.17, SD = 2.98) compared to those who also responded at T2 (M = 4.81, SD = 2.8; t (1236.738) = 2.68, p = .007, twotailed), indicating that job insecurity is associated with higher probability of dropping out from the study during the two-year time lag. No such tendency was found for laissez-faire leadership. Reference: Glambek, M., Skogstad, A., & Einarsen, S. (2018).
