Cognitive and Social Outcomes in Survivors Treated with XRT
versus PRT
Comparisons of social and cognitive outcomes between survivors treated
with XRT and PRT accounting for time since radiation are presented in
Table 3. Peer relations and social skills were similar across RT groups
(all F s < 1, p s > .8). The average
IQ score of the XRT group fell in the Below Average range of ability and
was significantly lower than that of the PRT group, which was Average
(p <0 .01). Cognitively, the XRT group performed
significantly worse than the PRT group on measures of processing speed
(p = 0.01) and verbal memory (p < 0.01). Effects
for executive functioning (p = 0.06) and verbal learning
(p = 0.07) approached significance. Survivors treated with XRT
and PRT performed similarly on a measure of sustained attention.
