RESUMO
AIM: The aim of this qualitative analysis was to establish the content validity of two new patient-reported outcome (PRO) measures: Sexual Arousal, Interest, and Drive Scale (SAID) and Hypogonadism Energy Diary (HED). METHODS: Four separate qualitative studies were conducted with 125 men with hypogonadism (mean age: 53 years, 85% adult onset). Study 1 used focus groups/interviews to identify important and relevant concepts related to the experience of hypogonadism and its treatment in men primarily with adult-onset hypogonadism. Study 2 tested items generated for assessments of low sex drive and low energy. Study 3 used interviews to confirm in men with early-onset hypogonadism that low sex drive and low energy were also important and relevant symptoms. Study 4 tested final versions of the two PROs and determined equivalency of paper-based and electronic versions of the two PROs. RESULTS: Of the concepts emerging in Studies 1 and 3, low sex drive and low energy were the symptoms most often spontaneously mentioned. Coding of transcripts from Studies 1 and 3 led to the generation of items for the SAID and HED. After item testing (Studies 2 and 4), the final SAID included five items pertaining to arousal, interest in sex and sex drive with a 7-day recall period and the final HED included two items (energy, tired/exhausted) to be administered three times per day. CONCLUSION: The SAID and HED have content validity established according to regulatory guidance and, therefore, the potential to provide the patient perspective of treatments for hypogonadism.
