This study spanned six waves with a six-month interval between each wave. Data from the last four waves were used because self-compassion or non-suicidal self-injury was not measured in the first two waves. The cross-lagged panel models were used to examine the longitudinal dynamic relationships between sleep disturbances, self-compassion, and non-suicidal self-injury.Results: The results showed that all the auto-regressive paths were significant. For the cross-lagged paths, there was a reciprocal relation between sleep disturbances and self-compassion. Importantly, self-compassion played a longitudinal mediating role in the prediction from sleep disturbances to non-suicidal self-injury (indirect effect = 0.007 to 0.009, all p values < 0.001).Conclusion: Psychological interventions targeting improved sleep quality and self-compassion may hold great promise for reducing the incidence of non-suicidal self-injury.Keywords: sleep disturbances, self-compassion, NSSI, longitudinal design
