BackgroundSelf-administered questionnaires provide a better alternative to disclose sensitive information in sexual health research. We describe the factors that determine the positive response initial recruitment to an initial invitation and subsequent completion of study to a postal questionnaire on sexual dysfunction.

MethodsSouth Asians SA and Europids with and without diabetes DM were recruited from GP clinics in UK. Men who returned the properly filled consent form ‘recruited-group’ were sent the questionnaire and those who returned it were considered as the ‘completed-group’. Index of Multiple Deprivation Scores IMDs were generated using UK postcodes. We calculated the recruitment rate and completion rate of the recruited and the study-completed groups respectively.

ResultsTotal approached sample was 9100 DM: 2914 32 %, SA: 4563 50.1 %. Recruitment rate was 8.8 % and was higher in Europids and in patients with DM. Mean IMDs for the recruited group was 20.9 ± 11.9, and it was higher among recruited SA compared to Europids p < 0.001. Mean IMDs was higher in the recruited group compared to non-recruited p < 0.01. All four recruited groups SA-Europid and DM-non-DM had lower IMDs compared to non-recruited. Completion rate was 71.5 % n 544 SA: 62.3 %, Europids: 77.4 %; p < 0.05.

ConclusionRecruitment for postal sexual health surveys is positively influenced by presence of investigated disease, older age, being from lesser deprived areas and Europid ethnicity. Furthermore, Europids were more likely to complete survey than South Asians irrespective of disease status.
