Adapting and Piloting Acceptance and Commitment Therapy (ACT) for Severe Premenstrual Mood Symptoms

In the weeks prior to menstruation, many individuals experience mood and physical symptoms that negatively impact their quality of life and functioning. Approximately 5% of women and menstruating individuals have such severe symptoms that they meet criteria for Premenstrual Dysphoric Disorder (PMDD). Further, of those with underlying mood disorders (i.e., depression, bipolar disorder) about 60% have cyclical worsening of symptoms classified as premenstrual exacerbation (PME). Both PMDD and PME are associated with significant impairment, yet limited effective options exist to treat these conditions. In this project, the investigators will adapt and evaluate an Acceptance and Commitment Therapy (ACT) group for PMDD and PME, entitled ACT-Premenstrual (ACT-PM), delivered virtually to maximize accessibility. The investigators will examine whether ACT-PM is feasible to deliver and whether it is acceptable to group participants and those facilitating the group. The study will lay the groundwork for future research to determine if the group is effective. If effective, the intervention could be scaled up to improve quality of life and outcomes for individuals suffering from PMDD and PME.

Emotion Regulation-based Internet-delivered Cognitive Behavioural Therapy for Premenstrual Dysphoric Disorder

Premenstrual dysphoric disorder (PMDD) is a debilitating cyclic mental disorder affecting about 2-5% of women of reproductive age. PMDD is characterised by recurring emotional, behavioural, cognitive, and somatic symptoms that arise during the luteal (premenstrual) phase of the menstrual cycle and remit shortly after the onset of menses. Although pharmacological interventions are available, many women experience residual symptoms, discontinue treatment or refrain from them because of side effects. Therefore, non-pharmacological treatment options are needed. Preliminary evidence suggests that internet-delivered cognitive behavioural therapy (ICBT) is a promising candidate, but further research is warranted. Also, there is room for treatment improvement. Specifically, it has been suggested that components targeting emotional and interpersonal dysregulation should be incorporated into CBT for PMDD. The current study aims to assess the effects of an ICBT intervention for PMDD incorporating skills training in emotion regulation and interpersonal effectiveness in a randomised controlled trial (RCT).

Pilot Study of the 'Thriving With PMDs' Program

This study is testing a self-help mental health program that was designed to help people cope with the challenges of living with a premenstrual disorder. Individuals with a premenstrual disorder - either premenstrual dysphoric disorder or premenstrual exacerbation of depression - will track their daily symptoms for two menstrual cycles before they complete the program, throughout the two-cycle program, and for an additional two cycles after accessing the program. This will allow the research team to compare their symptoms before and after accessing the program.
