“…In fact, major depression is the leading cause of disability in 15-44-year-old women (Murray & Lopez, 1996), and the likelihood of experiencing a recurrence of depression increases with each episode (Kovacs, 1997). The sex difference in depression appears to emerge around the time of adolescence (Angold & Rutter, 1992;Ge et al, 1994;Hankin et al, 1998;Petersen, Sarigiani, & Kennedy, 1991), is found within different ethnic groups (e.g., Grant et al, 1999) and with different sampling methods such as community-based (Lewinsohn, Hops, Roberts, Seeley, & Andrews, 1993;Offord et al, 1987;Spence, Najman, Bor, O'Callaghan, & Williams, 2002;Wichstrom, 1999) and high risk samples (Goodyer, Ashby, Altham, Vize, & Cooper, 1993;Grant & Compas, 1995). Initial episodes of depression are also more severe and longer in duration for girls than for boys (McCauley et al, 1993), and girls who experience depression for the first time in childhood or adolescence, compared to women with onsets later in life, have a prolonged period of risk for future episodes (Kovacs, 1997).…”
