title: Functional and dysfunctional impulsivity, depression, and suicidal ideation in a prison population.
abstract: D. Lester (1993) was not able to show any association between dysfunctional impulsivity and suicidal ideation, but he did find a negative correlation between suicidal ideation and functional impulsivity. The correlation was weak and was not significant when depression was controlled for. Given the fact that college students were the participants in that study, the low correlations may have resulted from insufficient variance in the data. In the current study, data were collected from prisoners (half of whom had recently attempted suicide); correlations among the variables were stronger (but still quite low) than the correlations found in Lester's study. As expected, the association between dysfunctional impulsivity and suicidal ideation was stronger than that between functional impulsivity and suicidal ideation. However, consistent with Lester's study, these correlations were not significant when depression was controlled for. Results indicate that a direct association between impulsivity and suicidal ideation is unlikely.
