Abstract
Polycystic Ovary Syndrome (PCOS) is an endocrine condition that has been associated with atypical emotional regulation strategy use as well as elevated levels of depression, anxiety, self-harm and suicidal ideation. Despite the existence of clinical screening guidance for this population, there is still little to no understanding of how non-suicidal self-injury and suicidal ideation and intention manifest in women with PCOS and how this might differ from women without PCOS. Within this cross-sectional investigation, women with and without a diagnosis of PCOS (n = 418) completed validated metrics of emotion dysregulation, rumination and non-suicidal self-injury (NSSI), as well as self-reported indices of previous suicidal ideation and future suicidal intention. Group comparisons indicated that women with, relative to those without, PCOS reported significantly greater metrics across all variables. Moreover, serial mediation analyses were conducted to test the ideation-to-action framework of suicide in women with PCOS, with the positive relationship between a PCOS diagnosis and future suicidal intention being explained through the indirect pathway of increased emotion dysregulation, recent suicidal ideation and NSSI. Our findings call to action the need for international screening for suicide intention and self-harm in women with PCOS.
