    Association Between Unaided Speech Perception in Noise and Hearing Aid Use Mediated by Perceived Benefit
    (2025) Marcotti, Anthony; Silva Letelier, Catherine Paola; Galaz-Mella, Javier; Ianiszewski, Alejandro; Vargas, Nicole B.; Fuentes López, Eduardo
    Background/Objectives: The conventional strategy for addressing age-related hearing loss is hearing aid (HA) use, yet many individuals underutilize their devices. Despite the positive effects of HA use, adherence remains low, highlighting the importance of studying associated variables. We hypothesize that better unaided speech perception in noise (SPiN) would be associated with greater perceived benefit from HAs, which, in turn, would be linked to increased HA use. Methods: A cross-sectional study design was used, including 114 older adults (≥65 years) who were HA users. HA use and perceived benefit were assessed using questions 1 and 2 of the International Outcome Inventory for Hearing Aids (IOI-HAs), while unaided SPiN performance was measured monaurally with a speech-in-noise test. In the mediation analysis, SPiN performance was the predictor, perceived benefit the mediator, and HA use the outcome. Direct and indirect effects were evaluated using generalized structural equation modeling. Results: No significant total effect was found for the right ear. For the left ear, there was a significant indirect effect of SPiN performance on HA use through perceived benefit (OR = 1.26, 95% CI 1.06–1.57, p = 0.019) but no direct effect (p = 0.563). In addition, a significant total effect of left ear SPiN performance on HA use was observed (p = 0.041). Conclusions: The findings suggest that unaided SPiN performance—particularly in the left ear—may be indirectly associated with HA use through its effect on perceived benefit. These results underscore the potential value of including SPiN assessments in the HA fitting process and counseling strategies for older adults.

    Cross-Cultural Adaptation and Validation of a Generic Acceptability Questionnaire to Spanish
    (2025) Rivera, Sebastián; Silva Letelier, Catherine Paola; Retamal Walter, Felipe; Fuentes López, Eduardo; Contreras, Jimena; Marcotti, Anthony; Alzate Pamplona, Fraidy Alonso
    To adapt and validate the generic TFA acceptability questionnaire to Spanish. Methods. In the initial phase of this two-phase observational study, a translation and adaptation of the original instrument was performed. The second phase con-sisted of applying this version to 194 older adults after a pilot hearing screening and a standard preventive medical examination. Construct validity was assessed by Exploratory Factor Analysis, and internal consistency with McDonald’s omega (ω). Results. Both procedures yielded the same two-factor solution. The first factor comprised items related to “affective attitude”, “perceived effectiveness”, “inter-vention coherence”, and “self-efficacy”; the second factor included items on “ethi-cality” and “opportunity costs”. The item ‘burden’ was removed due to its lack of significant factor loadings. The first factor accounted for 18.96% of the variance of the hearing screening and 26.28% of the preventive medical examination; the second accounted for 14.97% and 20.44%, respectively. Regarding reliability, the instrument demonstrated an ω = 0.61 for the hearing screening and ω = 0.73 for the preventive medical examination. Conclusion. The final instrument comprises six items evaluating specific acceptability constructs and one item addressing overall acceptability. It features a two-factor underlying structure, demonstrating high external reliability and acceptable internal consistency.

    Effectiveness of active communication education to improve hearing aid usage among Chilean older adults: a randomised clinical trial
    (2025) Marcotti, Anthony; Rivera, Sebastián; Silva Letelier, Catherine Paola; Martinez-Amezcua, Pablo; Fuentes López, Eduardo
    Objective: To assess the effectiveness of the Active Communication Education (ACE) program in improving usage, perceived benefit, and success with hearing aids (HAs).Design: A multicentre, double-blind, randomised parallel design clinical trial with masked outcome assessments was conducted at primary healthcare centres. Participants were randomised into either an intervention group (ACE) or a control group (social intervention). The primary outcome was HAs usage (question 1 of IOI-HA) and secondary outcomes were perceived benefit (question 2 of IOI-HA) and success with HAs (usage for at least 1 hour/day as per question 1 of IOI-HA and at least moderate perceived benefit as per question 2 of IOI-HA). Data collection occurred before, right after, and at 6 and 12 months following the intervention.Study sample: 114 older adults who use HAs.Results: The intervention group significantly increased HAs usage compared to baseline right after the intervention, as well as at 6- and 12-month follow-ups, in comparison to the control group. Secondary outcomes also showed improvements at all follow-up measurements, although these were less consistent.Conclusions: The ACE program is an effective strategy for enhancing HAs usage among older adults, with improvements that are sustainable over time.

    Effectiveness of the active communication education program in improving the general quality of life of older adults who use hearing aids: a randomized clinical trial
    (2024-10-12) Marcotti, Anthony; Rivera, Sebastián; Silva Letelier, Catherine; Galaz Mella, Javier; Fuentes López, Eduardo
    Abstract Background Hearing loss in older adults affects general, generic health-related and disease-specific quality of life (QoL). The conventional strategy to address it is through hearing aids, which have been shown to improve disease-specific QoL. However, the long-term results regarding general quality of life are unknown, and communication problems and stigma associated with hearing loss may persist. An effective intervention strategy to address these problems is group communication programs, most notably Active Communication Education (ACE). This program has been shown to increase communication strategies and reduce communication activity limitations and participation restrictions. These precedents allow us to hypothesize that this program could improve general QoL. Methods A randomized clinical trial was conducted on 114 older adult hearing aid users. Fifty-four subjects composed the intervention group that received the ACE program, while 60 subjects composed the control group that received an informational-lectures type intervention. The WHOQOL-BREF questionnaire was used to measure general QoL. Measurements were taken before and right after the intervention, with follow-ups at 6 and 12 months. Multilevel linear mixed models were estimated, considering the WHOQOL-BREF dimension scores and total score as the outcomes, and an interaction term between time since intervention and group as the predictor. Within- and between-group comparisons were made. Results Compared to the baseline time-point, the ACE group showed significant improvements right after the intervention, and at the 6-month and 12-month follow-ups for the dimensions of psychological health, social relationships, environment, and total score. Compared to the control group, the ACE group exhibited significantly greater improvements in the social dimension at all postintervention assessments, as well as in the environment dimension and total score at the 12-month follow-up. Conclusions The ACE program improved general QoL in terms of social relationships and environment dimensions, which lasted up to 12 months after the intervention. Therefore, ACE is positioned as an effective complement for HA users, enhancing and delivering new benefits related to broader aspects of QoL not necessarily tied to health. Trial registration ISRCTN54021189 (retrospectively registered on 18/07/2023).

    Interaction effect of self-efficacy and joint problems on hearing aid abandonment among older adults
    (2024) Fuentes-Lopez, Eduardo; Luna-Monsalve, Manuel; Silva-Letelier, Catherine; Marcotti, Anthony
    ObjectiveWe assessed the interaction between self-efficacy and joint problems and self-efficacy and visual problems on the risk of hearing aid abandonment in older adults. DesignA retrospective cohort study comprising older adults who received hearing aids in Chile was conducted. Hearing aid self-efficacy was measured using the S-MARS-HA questionnaire, while joint and visual problems were assessed through self-reported questions. Survival regression models were conducted to investigate the interaction between self-efficacy and joint problems, as well as self-efficacy and visual problems. Study sampleThe study included 355 older adults who received hearing aids through the Chilean public health sector. ResultsA significant interaction effect indicated that the relationship between self-efficacy and the risk abandonment was influenced by joint problems (p < 0.05). In the subpopulation with joint problems, self-efficacy was associated with a reduced risk of hearing aid abandonment (HR = 0.81), whereas in the subpopulation without joint problems, the protective effect was more pronounced (HR = 0.52). The interaction between self-efficacy and visual problems was not significant. ConclusionsThe interaction between self-efficacy and joint problems was associated with the risk of abandonment. Addressing limitations associated with joint problems and individuals' confidence in using their hearing aids could reduce the abandonment.

    Intervenciones parentales para el desarrollo lingüístico-comunicativo en preescolares con Trastornos del Neurodesarrollo: una revisión sistemática
    (2023) Vargas, Nicole B.; Godoy, María José; Jeraldo, Isidora; Orellana, Estefanía; Poblete, Ingeborg; Riveros, Sofía; Silva, Katherine; Marcotti, Anthony
    En el actual escenario sociosanitario enfrentado a raíz de la pandemia por SARS-CoV-2, múltiples actividades se han visto mermadas, e incluso, suspendidas por los largos periodos de aislamiento social y las medidas de cuidado para evitar contagios. En este sentido, muchas personas han dejado de recibir con la misma regularidad, o bajo las mismas circunstancias, sus tratamientos, incluyendo a niños con Trastornos del Neurodesarrollo (TND). Es así como surgen las intervenciones Parentales. Estas son programas donde los padres o cuidadores primarios son entrenados para llevar a cabo acciones terapéuticas con el niño y cuyo objetivo puede estar orientado a promover múltiples habilidades. El objetivo de la presente revisión sistemática fue determinar el efecto de estas intervenciones para promover el lenguaje y la comunicación en niños con diagnóstico de TND de entre 2 y 5 años. Se realizó una búsqueda sistemática en las bases de datos ERIC, MEDLINE y PubMed, considerando publicaciones de entre enero del 2010 y marzo de 2022. De las 9885 referencias iniciales, y posterior a las etapas de tamizaje y elegibilidad, 5 fuentes primarias cumplieron con los criterios de selección. Los resultados indican que las intervenciones parentales para habilidades de comunicación serían efectivas e incluso se mantendrían los efectos en medidas de seguimiento. En cuanto a las habilidades de lenguaje, los resultados a través de los estudios son contradictorios. Por otra parte, ninguno de los estudios reporta efectos adversos para los niños. En cuanto a efectos beneficios o adversos para padres o cuidadores primarios, ninguno de los estudios incluidos reporta medidas asociadas.

    Normalization of Rowland Universal Dementia Assessment Scale (RUDAS) in Chilean older people
    (2023) Sepúlveda Ibarra, Consuelo; Henríquez Chaparro, Fernando; Marcotti, Anthony; Soto, Guillermo; Slachevsky, Andrea
    Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive screening that evaluates older people with low educational levels. In Chile, there are no normative data to assess this population. Objective: To obtain normative data on RUDAS in older Chilean people with up to 12 years of schooling, and to determine whether age and schooling years influence a person’s performance on RUDAS and on the items that constitute it. Methods: A group of cognitively healthy people 60 years old or over, with up to 12 schooling years was evaluated (n=135). Multiple regression models were applied to obtain normative data on RUDAS, according to age and schooling years, and to measure the effects of schooling on different items. Results: Regression analysis showed that none of the items had schooling as a significant predictor, except for the visuoconstruction item. The variables age and schooling explained 12.6% (R^2=0.126) of the RUDAS total score variance. The item visuoconstruction was the most associated with the educational level (OR=1,147). Conclusion: This study showed that RUDAS is a recommended instrument for evaluating older people with low educational levels. However, more studies are needed to prove the validity of the RUDAS on Chilean older people.

    Usefulness of low-cost infrared goggles for the assessment of spontaneous nystagmus
    (2024) Waissbluth Abarca, Sofía; Aracena Carmona, Karina Andrea; Gallardo Cares, Macarena Omaira; García-Huidobro N., Francisco; Oyarzún Aguirre, Ignacio Javier; Marcotti, Anthony
    Introduction: Due to its precision and simplicity, videonystagmography is the most used technique for evaluating eye movements in patients with vestibular complaints. However, its high cost limits its widespread use. In response, the development of lowcost goggles emerged as an alternative to traditional videonystagmography equipment. Objetives: This study aimed to compare the performance between low-cost goggles and videonystagmography in assessing spontaneous nystagmus. Materials and Methods: We conducted a cross-sectional study at the Department of Otolaryngology at the Red UC Christus. Patients referred for vestibular evaluation were assessed using both videonystagmography and a prototype of low-cost goggles. Two blinded clinicianswith varying levels of expertise reviewed recordings from both tests to identify spontaneous nystagmus. Results: Of 104 participants, 56.7% exhibited spontaneous nystagmus detected by videonystagmography. The low-cost goggles demonstrated a concordance of κ = 0.60 for nystagmus detection and κ = 0.47 for classification when used by the less experienced clinician. The more experienced clinician achieved a concordance of κ = 0.82 for detection and κ = 0.73 for classification.
