Brief Summary
Premenstrual Dysphoric Disorder (PMDD) is a cyclical mood disorder characterized by emotional, cognitive, physical, and sleep-related symptoms that occur in the days leading up to menstruation and improve shortly after menstruation begins. Although medications are commonly used to treat PMDD, many individuals experience side effects, do not benefit from medication, or prefer non-medication-based approaches. Sleep difficulties are very common in individuals with PMDD and may contribute to mood symptoms, emotional regulation difficulties, and functional impairment. Psychological interventions that focus on sleep, such as sleep psychoeducation and cognitive-behavioural strategies for insomnia, are effective in other mood and anxiety disorders but have not been well studied in PMDD. This study aims to evaluate the feasibility, acceptability, and preliminary effects of a brief, sleep-focused psychoeducation workshop tailored for individuals with PMDD or severe premenstrual symptoms. Information collected in this study may help inform future research and may improve care for individuals with PMDD.

Outcome Measures
Primary Outcomes (2)
Insomnia Severity Index (ISI)
Description: The ISI is a 7-item self-report questionnaire that assesses the nature, severity, and impact of insomnia. Items are scored on a 5-point Likert scale ranging from 0 ('no problem') to 4 ('very severe problem') with higher scores reflecting greater insomnia severity. Total scores between 0-7 indicate an absence of insomnia; scores between 8-14 suggest sub-threshold insomnia; scores between 15-21 indicate moderate insomnia; and scores between 22-28 suggest severe insomnia. The ISI has demonstrated good psychometric properties.
Throughout the duration of the study (60 days), change will be assessed weekly.
Actigraphy watches
Actigraphy watches are wrist-worn and battery-operated activity monitors that look similar to a small wristwatch. These devices are equipped with an accelerometer, measuring activity patterns and estimating sleep. They can be employed as an adjunctive measure in the diagnosis and treatment of insomnia to improve the reliability of self-report estimates of sleep.
Actigraphy watches will be worn daily for 60 days for all participants.

Study Arms (2)
Treatment Group
EXPERIMENTALIf you are assigned to the treatment group, you will complete 30 days of daily monitoring before attending one 90-minute virtual sleep-focused psychoeducation workshop led by a trained graduate student under the supervision of a senior licensed clinical psychologist, Dr. Sheryl M. Green. The workshop will include education about PMDD, sleep physiology, sleep hygiene, and cognitive- behavioural strategies for improving sleep. After the workshop, you will continue daily monitoring for an additional 30 days.
Waitlist
NO INTERVENTIONIf you are assigned to the waitlist group, you will complete the same 60 days of daily monitoring but will not receive the workshop during the study period. You will be offered the opportunity to participate in the workshop after completing the study, if you are interested.
Interventions
The workshop will include education about PMDD, sleep physiology, sleep hygiene, and cognitive- behavioural strategies for improving sleep.

- reported regular menstrual cycle (average length of 25-35 days)
- not taking psychoactive medication or oral contraceptives or a) participants must be on a stable in dose and type for at least 8 weeks prior to the start of the study and b) medications remain stable throughout the study
