Suicidal ideation in psoriasis

Int J Dermatol. 1993 Mar;32(3):188-90. doi: 10.1111/j.1365-4362.1993.tb02790.x.


Background: Psoriasis has been associated with depressive disease and case reports of completed suicide.

Methods: 217 consenting psoriasis patients completed the Carroll Rating Scale for Depression (CRSD), a 52-item self-rated scale, with four of the items directly addressing wishes to be dead and suicidal ideation. The patients also self-rated the severity of their psoriasis.

Results: 9.7% of patients reported a wish to be dead, and 5.5% reported active suicidal ideation at the time of the study. The death wish and suicidal ideation were associated with higher depression scores (P < 0.0001) and higher patient self-ratings of psoriasis severity (P < 0.05). Patient self-reports of psoriasis severity correlated directly with the overall depression scores (r = 0.39), P < 0.0001).

Conclusions: The comorbidity between depressive symptoms, suicidal ideation, and psoriasis severity is in contrast with reports that severe depression and suicidal ideation are mainly a feature of life-threatening medical disorders such as malignancies. Our finding may have important implications in the management of psoriasis.
