Study Instruments. The original study team developed two separate interviewer guides for the MSM- LWH and the subsample of their HIV-discordant partners. The beginning of the interviewer guide included a close-ended quantitative portion that asked for demographic, SES, and household information. These items were asked for both MSM-LWH and HIV- discordant partner samples. The open-ended interview guide included questions about HIV diagnosis and testing history, social support, experience with treatment, and perceived barriers to HIV care and treatment adherence. This method of using a semi- structured interview guide allowed study participants to provide detailed responses and discuss other concerns. Two questionnaires were also developed to ensure that the open- ended items were pertinent to issues specific to MSM-LWH and HIV-discordant partner participants and to inform the development of culturally appropriate, tailored interventions for MSM-LWH from various socioeconomic categories and geographic locations to reduce barriers related with engagement and retention in HIV care and treatment. Survey Measures. All study participants also completed brief sociodemographic questionnaires at the beginning of the study visit. The questionnaire was incorporated into the interview guide for subsequent quantitative analyses. The questionnaires consisted of items related to demographics, including household living arrangements, employment, and insurance status among other standard demographic questions (e.g., age and racial/ethnic status).
Study Instruments. Semi-structured interview guides were developed for in-depth interviews with operated and unoperated women and for focus group discussions with heads of households (Appendices IV- VI). Questions were categorized into four main themes: 1) definition of a quality life; 2) how trichiasis did or did not affect this ideal; 3) how surgery affected pre-surgical quality of life and perceptions of trichiasis surgery; and 4) the decision-making process, including factors influencing health-seeking behaviors and presenting for trichiasis surgery. Interview guides were developed in French, discussed by the study team and translated into Hausa, before being back-translated by an independent person to ensure quality translation. Study instruments were pre-tested in a non-study village during the training phase. Interviewers were asked to follow the interview guides and ask follow-up questions and probes based on participant responses. For the in-depth interviews, interviewers were instructed to direct questions to the woman with operated or unoperated trichiasis and ask her friend/confidante to confirm or add to statements made by the trichiasis patient.
Study Instruments. The structured questionnaire (annex3) was developed to record patient data from the electronic file. The main items of this questionnaire were included: • Demographic and personal data. • Medical histories such as patient complains and family history of the disease. • The number of consultations before the diagnosis. • Diagnostic data and diagnostic process. • Potential complication during MRI screening such as allergy reactions. • Examination and result duration. • The differential variables accuracy of diagnosis was obtained from MRI and histopathology reports records and measure the agreement between them. • The collected data was used as data entry for the proposed statistical model.
