Are you in therapy? While therapy is going on, people may feel many ways about their therapist - sometimes happy with their therapist, sometimes mad at their therapist, sometimes other feelings. We are conducting a study to validate two questionnaires aimed at measuring how people feel about their therapists and their relationship with them during their psychotherapy sessions. You may qualify if you are over 18 years old, fluent in English, and under psychotherapy treatment. If you decide to participate in this, you will be asked to rate your feelings related to your last session with your therapist and the week preceding it. By joining this study, you will help us validate two evidence-based questionnaires for assessing how patients feel during a therapy session. In addition, filling out it may be a chance for you to further reflect on both your feelings toward the therapeutic relationship and your psychotherapist. This

The study would also like to enroll a few people that TEST NEGATIVE, but have symptoms of a respiratory illness, in order to determine the reliability of the test.
