Preset hearing aids, which offer user-selectable pre-developed amplification programs, may support such models, but little is known about their real-world use and alignment with clinical recommendations. Method: This longitudinal study formed part of a feasibility project implementing the World Health Organization\u2019s (WHO\u2019s) hearing aid service delivery approach in three low-income South African communities. Adults (\u226518 years) with confirmed moderate-to-severe bilateral hearing loss were fitted with preset hearing aids by trained CHWs. Devices offered four preset amplification programs. Participant-driven selections were recorded at four distinct time points: fitting and follow-ups at 2 weeks, 2 months, and 6 months post-fitting. Results: In total, 36 participants (mean age = 76 years, SD = 8.9, range 50\u201396) were fitted with devices. Although over half (right: 52.8%, left: 58.3%) presented with high-frequency loss, only 34% initially selected the corresponding program. Most participants (80.6%, n = 29) changed their selections at least once over the six months. Significant associations between hearing loss configuration and selection occurred at some time points only in the left ear, but agreement with clinically recommended programs declined from 42% at baseline to 28% at six months. Conclusions: CHW-facilitated hearing aid delivery supports user autonomy in low-resource settings. However, frequent changes and divergence from clinically recommended programs suggest reliance on user-driven trial-and-error adjustments rather than audiometric fit, which may limit long-term benefit. Ongoing, person-centred guidance is needed for the effective use of preset hearing aids.<\/jats:p>","DOI":"10.3390\/audiolres15050137","type":"journal-article","created":{"date-parts":[[2025,10,13]],"date-time":"2025-10-13T08:10:31Z","timestamp":1760343031000},"page":"137","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Preset Hearing Aid Program Selection in Low-Income Communities: A Longitudinal Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-2640-0228","authenticated-orcid":false,"given":"Ann\u00e9","family":"Croucamp","sequence":"first","affiliation":[{"name":"Department of Speech-Language Pathology and Audiology, University of Pretoria, Pretoria 0028, Gauteng, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9922-2927","authenticated-orcid":false,"given":"Caitlin","family":"Frisby","sequence":"additional","affiliation":[{"name":"Department of Speech-Language Pathology and Audiology, University of Pretoria, Pretoria 0028, Gauteng, South Africa"},{"name":"Virtual Hearing Lab, a Collaborative Initiative Between the University of Colorado and the University of Pretoria, Aurora, CO 80045, USA"},{"name":"hearX Foundation, Pretoria 0081, Gauteng, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1254-8407","authenticated-orcid":false,"given":"Vinaya","family":"Manchaiah","sequence":"additional","affiliation":[{"name":"Department of Speech-Language Pathology and Audiology, University of Pretoria, Pretoria 0028, Gauteng, South Africa"},{"name":"Virtual Hearing Lab, a Collaborative Initiative Between the University of Colorado and the University of Pretoria, Aurora, CO 80045, USA"},{"name":"Department of Otolaryngology-Head and Neck Surgery, University of Colorado School of Medicine, Aurora, CO 80045, USA"},{"name":"UCHealth Hearing and Balance, University of Colorado Hospital, Aurora, CO 80045, USA"},{"name":"Department of Speech and Hearing, School of Allied Health Sciences, Manipal Academy of Higher Education, Manipal 576104, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tersia","family":"de Kock","sequence":"additional","affiliation":[{"name":"Department of Speech-Language Pathology and Audiology, University of Pretoria, Pretoria 0028, Gauteng, South Africa"},{"name":"hearX Foundation, Pretoria 0081, Gauteng, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8313-1636","authenticated-orcid":false,"given":"De Wet","family":"Swanepoel","sequence":"additional","affiliation":[{"name":"Department of Speech-Language Pathology and Audiology, University of Pretoria, Pretoria 0028, Gauteng, South Africa"},{"name":"Virtual Hearing Lab, a Collaborative Initiative Between the University of Colorado and the University of Pretoria, Aurora, CO 80045, USA"},{"name":"Department of Otolaryngology-Head and Neck Surgery, University of Colorado School of Medicine, Aurora, CO 80045, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,11]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2021).
