Longitudinal Predictors of Mother-reported Survivor Quality of
Life
A hierarchical regression model examined baseline predictors of
mother-report of survivor quality of life at 5-year follow-up. The first
step examined mother’s age and the sociodemographic score. This model
was significant, F (2,77) = 8.38, p < .001, and
explained 18% of the variance in QOL. The sociodemographic score was
the sole significant predictor (β = -0.39, p <
.001). The second step added mother-report of survivor’s cancer-specific
stress and mother’s general stress, which contributed an additional 38%
of explained variance in QOL, ΔF (2,75)=32.41,p <.001. Both mother-report of survivor’s
cancer-specific stress (β = -0.39, p < .001) and
mother’s general stress (β = -0.46, p < .001)
were significant predictors of QOL, but the sociodemographic score was
no longer a significant predictor. Finally, mother–adolescent
communication was added in the third step of the model and contributed
an additional 3% of variance in QOL, ΔF (1,74) = 5.26, p =
.03. This final model was significant, F (5,74) = 21.18, p< .001, and explained 59% of the total variance. With the
addition of mother–adolescent communication, survivor’s stress
(β = -0.37, p < .001), mother stress (β =
-0.42, p < .001), and communication (β = 0.19,p = .03) were all significant predictors of quality of life
(Table 3).
