PTSD Checklist for Diagnostic and Statistical Manual (DSM)-5 (PCL-5)
Time frame · Up to 12 months follow up
The PTSD Checklist for DSM-5 (PCL-5) is a self-report questionnaire designed to assess the severity of PTSD symptoms in alignment with the DSM-5 diagnostic criteria. A total symptom severity score (range - 0-80) will be obtained by summing the scores for each of the 20 items with higher scores indicating greater symptom severity. Data Collected: Group/Sequence A: Baseline, pre-PS, pre-IM/5Meo, pre-MeRT, mid-MeRT, Post-MeRT, 3 MFU, 6 MFU, 12 MFU; - Group/Sequence B: Baseline, pre-PS, pre-MeRT, mid-MeRT (week 3 MeRT), pre-IM/5Meo, post-IM/5Meo, 3 month follow up (MFU), 6MFU, 12MFU.
Medical Outcomes Study Cognitive Functioning Scale (MOS-CF)
Time frame · Up to 12 months follow up
The Medical Outcomes Study - Cognitive Functioning (MOS-CF) self-report scale consists of 6 items that are designed to measure perceived cognitive functioning. Each item is scored on a 6-point scale (1-6), with 1 being 'all of the time' and 6 being 'none of the time.' Higher scores indicate higher cognitive functioning and lower cognitive symptoms. Collected - Group/Sequence 1: Baseline, pre-HRT, pre-MeRT, mid-MeRT (week 3 MeRT), pre-Ibo/5Meo, post-Ibo/5Meo, 3 month follow up (MFU), 6 MFU, 12 MFU; Group/Sequence 2: Baseline, pre-HRT, pre-Ibo/5Meo, pre-MeRT, mid-MeRT, Post-MeRT, 3 MFU, 6 MFU, 12 MFU
Stroop Squared Task
Time frame · Up to 12 months follow-up
In the Stroop Squared Task, participants will select words corresponding to the color of the stimulus word given. For example, participants will name the color of the ink a word is printed in while ignoring the word itself (e.g., the word "BLUE" printed in red ink). The task primarily measures cognitive inhibition. Each participant will receive one score indexing the delay in reaction time caused by the mismatch between word and color.
Data Collected: Group/Sequence A: Baseline, pre-PS, pre-IM/5Meo, pre-MeRT, mid-MeRT, Post-MeRT, 3 MFU, 6 MFU, 12 MFU; - Group/Sequence B: Baseline, pre-PS, pre-MeRT, mid-MeRT (week 3 MeRT), pre-IM/5Meo, post-IM/5Meo, 3MFU, 6MFU, 12MFU.
Externalized Free Recall with Emotional Words Task
Time frame · Up to 15 weeks (Post-MeRT for Group A, Post-IM/5MeO for Group B)
In the Externalized Free Recall with Emotional Words Task, participants will be presented with a series of emotionally positive, negative, and neutral stimuli (e.g., words or images) and asked to recall the stimuli. The task captures how well individuals retain and recall emotional versus neutral content. Dependent variables include:
V1. The proportion of total words correctly recalled of total words administered V1.1. The proportion of recalled negative words of all words recalled V1.2. The proportion of recalled positive words of all words recalled V1.3. The proportion of recalled neutral words of all words recalled V2. The absolute number of total recall intrusions V2.1. The proportion of intruding negative words of all intruding words V2.2. The proportion of intruding positive words of all intruding words V2.3. The proportion of intruding neutral words of all intruding words Data Collected: Group/Sequence A: pre-PS, Post-MeRT; Group/Sequence B: pre-PS, post-IM/5Meo.
