s as a mediator and each PSI-SF subscale as dependent variables.  Regarding the Parental Distress subscale, the results (see Table [0](#T0){ref-type="table"}) indicated that the total effect (*c path*) of PTS symptoms on this dimension of parenting stress (Coeff. = 0.00; *p* \< 0.000) was significant. The results also illustrated that sleep disturbances were significantly associated with the mediator sleep difficulties (Coeff. = 0.00; *p* \< 0.000; *a path*). The mediator's effect on PD was significant (Coeff. = 0.00; *p* \< 0.000; *b path*). The direct effect of sleep disturbances on PD was also significant (Coeff. = 0.00; *p* \< 0.000; *c*′ *path*).
