The 'Teens Thetas became even more involved in campus affairs, participating in May Day celebrations, variety shows, and more sports such as swimming, track, basketball, fencing, and tennis. Chapters voted to support the honor systems being implemented on many campuses, and scholarship became a focus. Thetas became involved in World War I as nurses, doctors, canteen workers, librarians, and social workers in the Red Cross, YMCA, YWCA, medical corps, and governmental departments. Thetas knitted sweaters for troops, funded base hospitals, and supported war orphans and overseas reconstruction work. Questions of appropriate behavior were subjects for chapter discussion. Some chapters voted not to participate in "objectionable" dances like the Tango or the Rag. Fashions during the decade included long-waisted, wide-hipped shapeless dresses, and middies with ties and long pleated skirts. Rag time music was the rage, and coeds danced the Two-Step and the Cake Walk to records turning round and round on Victorolas. New Theta chapters were established at North Dakota, South Dakota, Washington State, Cincinnati, Washburn, Sophie Newcomb, Purdue, Lawrence, Pittsburgh, Randolph-Macon Women's College, Colorado State, Arizona, Oregon State, Oklahoma State, and Pennsylvania.
