Degrees of freedom for Step 1, F(3, 148); for Step 2, F(5, 146); for Step 3, F(8, 143); and for Step 4, F(11, 140). * p < 0.05. ** p < 0.01. *** p < 0.001. PB = perceived burdensomeness; TB = thwarted belongingness; SD = self-disclosure; PGS = prolonged grief symptoms as measured by the PG-13-R scale. ¹ no. months.
