- Treatment Satisfaction Questionnaire for Medication (TSQM) [ Time Frame: 6 weeks ]The TSMQ is a brief questionnaire asking patients about how satisfied they were with the ease, timing, etc. of the study medication giving a good indication of adherence
- Childhood Trauma Questionnaire (CTQ) [ Time Frame: 6 weeks ]The CTQ is a validated measure of adverse early experiences characterized on a measure of Anxiety Sensitivity Index and retrospective childhood maltreatment. A 5-point frequency of occurrence scale is utilized: (1) never true, (2) rarely true, (3) sometimes true, (4) often true, and (5) very often true. Each sub-scale score ranges from 5 (no history of abuse or neglect) to 25 (very extreme history of abuse and neglect).
- Experience Close Relationships (ECR) [ Time Frame: 6 weeks ]The ECR is a self-rated questionnaire designed to assess individual differences with respect to attachment-related anxiety (i.e., the extent to which people are insecure vs. secure about the extent to which their partner's availability and responsiveness) and attachment-related avoidance (i.e., the extent to which people are uncomfortable being close to others vs. secure depending on others) .
