 - Documented or self-reported current pregnancy, current breast-feeding, or recently pregnant girls within 1 year of delivery. Because pregnancy is a state in which weight gain is expected and appropriate, pregnant individuals would not be suitable for this study. Sexually active females must be using an effective form of birth control. These methods include total abstinence no sex, oral contraceptives the pill, an intrauterine device IUD, levonogestrol implants Norplant, or medroxyprogesterone acetate injections Depo-provera shots. If one of these cannot be used, contraceptive foam with a condom is recommended. Should a participant in the IPT-WG group become pregnant during the 12 weeks of the group program, she will be excluded from the group sessions. The study team will closely assist in obtaining an appropriate referral to a community mental healthcare provider, as indicated, and will request a release of information so that they may facilitate a smooth transition for the girl.
