N = 658. Number of bootstrap samples for bias corrected bootstrap confidence intervals: 10,000. Level of confidence for all confidence intervals: 95%. X, ERR; M1, perceived organizational support; M2, psychological capital; Y, insomnia symptoms. Model 1, ERR—perceived organizational support—insomnia symptoms; Model 2, ERR—psychological capital—insomnia; Model 3, ERR—perceived organizational support—psychological capital—insomnia symptoms.
