In a similar vein, research shows a link between self-identification with "darkness" and depression, however a causal link in this relationship has not be supported.
More specifically, Bowes et al. (2015) found that teens that identified as "goth" were more likely to self-report depression, as compared to teens who did not identify with this sub-culture. While findings suggest that identification with goth culture is associated with depression, a causal link can not be implied. Data was obtained from the Avon Longitudinal Study of Parents and Children (Bowes et al., 2015). Sample participants were approximately 15 years old at the first time point, and 18 years old at the second.
