Understanding suicide risk in Premenstrual Dysphoric Disorder (PMDD) - Expanding the integrated motivational-volitional (IMV) model of suicidal behaviour

Disclaimer: Our study is ongoing. Full methods and findings will be published soon. This poster highlights our interim findings. Background: Premenstrual Dysphoric Disorder (PMDD) is a severe hormone based mood disorder, characterised by emotional dysregulaton, suicidal ideation and high rates of self-harm. One in twenty women and people who menstruate have PMDD. One in three people with PMDD attempt suicide. Aim: Our study aims to adapt the Integrated Motivational-Volitional (IMV) model of suicidal behaviour (O'Connor et al) for use within the PMDD population. Methods: Our five phase study includes: (1) thematic analysis of focus group and interviews with people living with PMDD; (2) qualitative insight from four focus groups with professional stakeholders; (3) an online survey and online stakeholder workshop; (4) identification of IMV-model as an adaptable tool for suicide prevention in people with PMDD; and (5) a systematic review of risk and protective factors and their association with PMDD. Interim findings: Our interim analysis has resulted in a draft adapated IMV-model for PMDD. All white sections of the visual model represent elements of the original IMV-model constructs. All teal coloured sections represent PMDD-specific factors to be considered in the support of people with PMDD. These PMDD-specific factors fluctuate across the phases of the menstrual cycle, with the luteal phase (approximately days 14-28 of the cycle) being high risk for suicidality. Next steps: On completion of our analysis, the adapted model will be evaluated by health professionals involved in the care of those with PMDD. We will explore which factors of the adapted model help identify increased risk of suicadilty for individuals with PMDD. We will also gather insight from stakeholders on potential use of the model in practice settings. 🔗 To see our other PMDD studies please visit www.pmddresearch.com
