She gathered two groups of men: one group would be exclusively homosexual, the other exclusively heterosexual. She contacted the Mattachine Society to find a large portion of homosexual men. The Mattachine Society was an organization whose purpose was to integrate homosexuals into society. She had greater difficulty finding heterosexual men for the study. She gathered a sample of 30 heterosexual men and 30 homosexual men and paired them based on equivalent IQ, age, and education. For the interest of the study, it was required that none of the men from either group have previously been seen for psychological help, in disciplinary barracks in the armed services, in prison, showed evidence of considerable disturbance, or who were in therapy. She also had to use her home to conduct the interviews to protect the participants' anonymity.
