Some children experience persistent night-time fears that interfere wi
th their daily functioning. Initially, we present developmental consid
erations necessary to an understanding of sever night-time fears. We p
ostulate that severe night-time fears are probably due to a complex in
teraction of biological, environmental, and cognitive-mediational proc
esses. Several assessment procedures are outlines: behavioral intervie
ws, diagnostic interviews, fear survey schedules for children, home mo
nitoring on the part of parents, and darkness toleration tests. Tradit
ional behavioral interventions, and more recent cognitive-behavioral i
nterventions, are evaluated in terms of their research foundations. Co
gnitive-behavioral strategies appear to have the more empirical suppor
t, although we draw attention to several methodological limitations. (
