Contributions to Perinatal Mental Health Science

  1. Virtual care perinatal interventions. A sub-theme of Dr. Dennis’ research program is the use of technology to increase access and “reach” to effective care especially among disadvantaged populations and those living in rural and remote areas. She has conducted numerous prevention and treatment clinical trials to deliver interventions provincially and nationally and is currently evaluating a collaborative virtual care intervention with depressed women across Canada as a new approach to the management of perinatal mental illness.
  2. Cochrane systematic reviews. Dr. Dennis became a member of the Cochrane Collaboration in 2000 and has led the majority of Cochrane systematic reviews and meta-analyses related to perinatal mental health including: (1) Oestrogen and progesterone therapy for preventing and treating postpartum depression; (2) Psychosocial and psychological interventions for preventing postpartum depression; (3) Psychosocial and psychological interventions for treating antenatal depression; (4) Psychological and psychological interventions for treating postpartum depression; (5) Interventions (other than psychosocial, psychological, and pharmacological) for treating antenatal depression; (6) Psychosocial, psychological, and pharmacological interventions for treating antenatal anxiety; (7) Interventions (other than psychosocial, psychological, and pharmacological) for treating postpartum depression; and (8) Interventions (other than psychosocial, psychological, and pharmacological) for preventing postpartum depression.
