Participants will participate online to the 6 sessions of the program addressing the psychological experience of pregnancy and supporting reflective capacities.

Participants of the comparison group will receive usual prenatal cares (ex. prenatal classes)

The program is offered by two facilitators to groups of three to six women, online in a synchronous mode. The intervention is divided into two phases, each including three sessions. The first 3 sessions aim to explore how the participants feel, to better understand what makes them feel this way, to allow them to exchange with other people who are going through similar experiences, and to support the ability to manage stress and more unpleasant emotions. The following three sessions aim to enable participants to refocus on their experience of pregnancy and motherhood by giving them the opportunity to reflect upon how they wish to be as mothers, upon how their personal history influences their experience of pregnancy and motherhood, upon the moments that, as mothers, might be the most pleasant and those that will require more adaptations, and upon identifying the needs they have or expect to have after childbirth as well as the resources available to them to meet these needs.

Participants are invited to complete a self-report questionnaire (Kessler Distress Scale) assessing psychological distress. Change between baseline and end of pregnancy will be assessed, as well as between baseline and 6-month postpartum.

We developed an instrument assessing one's perception of change (negative change to positive change) across multiple domains of functioning including the quality of the relationship with the partner; the quality of the relationship with significant others, self-esteem; emotion recognition, regulation and expression; social support and parental confidence. These domains will be assessed separately.

Participants are invited to complete a self-report questionnaire of post-traumatic growth (Post-traumatic Growth Inventory) at the end of the third trimester of pregnancy. Scores in participants to the intervention will be compared to scores of matched controls who did not participate to the intervention.

Participants are invited to complete a self-report questionnaire assessing their level of satisfaction after each session and at the end of the program, using a Likert scale. A semi-structured interview is also administered at the end of the program that will provide qualitative information regarding their appreciation of the program.

Participants will complete the Parental Reflective Functioning Questionnaire (PRFQ) at 6 months postpartum. Scores in participants to the intervention will be compared to scores of matched controls who did not participate to the intervention.

Personality dysfunctions are assessed at baseline and will be considered as a moderator of the intervention effectiveness. Personality dysfunctions will be measured using the Self and Interpersonal Functioning Rating Scale, a 24-item self-report questionnaire designed to assess the four core elements of personality pathology (Identity, Self-direction, Empathy, and Intimacy) from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Level of Personality Functioning for personality disorders.
