Project SIGMA (Socio-sexual Investigations of Gay Men and Aids)

Microfiche of anonymised diaries (only age and occupation were recorded) of sexual behaviour kept by gay and bisexual men in connection with this longitudinal survey 1987-1994, with associated documentation. The diaries were developed as a method within Project SIGMA (which was supported by grants from the Medical Research Council, the Economic and Social Research Council, and the Department of Health) to provide unique and detailed information about gay and bisexual men's sexual activity and the contexts within which it occurred. Diary keepers were asked to keep a diary on a daily basis for the period of a month, referring not only to the partner/s involved but also to the day, time and setting in which the sexual activity occurred. The data give information on the sequence in which things happened, on the roles (solo/active/passive/mutual) taken. If ejaculation occurred, its destination (in/on a partner, into a condom) was also noted. Any use of toys, "poppers", drugs etc. were recorded in the context in which they were used. Because diaries were filled out on a daily basis, recall biases were lessened.
