Nolen-Hoeksema
and Morrow (1991) had the good fortune to have measured depression among college
students 2 weeks before the Loma Prieta earthquake in California in 1989. Nolen-Hoeksema
and Morrow collected repeat data to track the students’ adjustments to the
earthquake. Measurements were taken every 3 weeks starting 2 weeks before the
earthquake to 10 weeks after. The data were recreated by Howell (1999) based on
the Nolen-Hoeksema and Morrow findings. Each row gives the depression scores for
one student.
