Perinatal Grief Scale (PGS) |
Portuguese adaptation of Perinatal Grief Scale- PGS (Rocha, 2004) assesses changes pre and post-intervention, in three subscales that involve perinatal grief symptomatology like active grief, difficulty coping and despair. This scale comprises 33 items divided into three subscales that assess active grief, difficulty coping, and despair. Minimum score of 33 and a maximum 165- higher scores represent more severe grief symptoms. |
Pre-intervention (1 week before the beginning of the intervention) and Post-intervention (4 to 5 weeks after the beginning of the intervention) |

Posttraumatic Stress Disorder Checklist (PCL-5) |
The Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) adapted to the Portuguese population, will be used to evaluate post-intervention changes in post-traumatic stress symptoms. This is a 20-item self-report instrument that assesses the 20 DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) symptoms of PTSD rated from 0 to 4. A minimum score of 0 and a maximum of 80- higher scores represent more severe post-traumatic stress symptoms. |
Pre-intervention (1 week before the beginning of the intervention) and Post-intervention (4 to 5 weeks after the beginning of the intervention) |

Primary |
Hospital Anxiety and Depression Scale (HADS) |
HADS is a 14-question instrument that measures anxiety and depression with seven questions for each; each question is scored between zero (no impairment) and three (severe impairment), with a maximum score of 21 for anxiety or depression. |

System Usability Scale (SUS) |
For assessing the overall usability of the prototype, the System Usability Scale (SUS) is a widely used scale that provides a global view of subjective assessments of usability. Scoring varies from 0 to 100, and the bigger the value better the usability assessment. |
Post-Intervention (4-5 weeks after the beginning of the intervention) |

Sense of Presence Inventory (ITC) |
To assess the VR user experience, the ITC - Sense of Presence Inventory adapted to the Portuguese population by Raposo-Vasconcelos et al. will be used. This scale has two parts, the first addressing the user's feelings after the experience, and the second related to the characterization of the experience during the simulation. This inventory includes 44 items organized into four factors: Sense of physical space, Engagement, Ecological validity, and Negative effects. The mean score for each factor can vary from 1 to 5. |
Post-Intervention (4-5 weeks after the beginning of the intervention) |

Secondary |
User Experience questionnaire |
A customized questionnaire with open questions where participants can freely elaborate on any issues related to the VR prototype. Only qualitative data will be analysed with this questionnaire. |
