Abstract Introduction Hearing impairment is a common disease worldwide, with a comprehensive impact, and cochlear implantation (CI) is an intervention for profound hearing impairment. Objective To study the outcome one and three years after unilateral CI on hearing, health-related quality of life and level of depression and anxiety, and the correlation between the outcomes. Second, to study whether age, gender, etiology, operated side, residual hearing or cognitive performance can predict the outcome. Methods A prospective longitudinal study including adults with profound postlingual hearing impairment, with respect to hearing (speech recognition), health-related quality of life (Health Utilities Index 3) and level of depression and anxiety (Hospital Anxiety and Depression scale), pre-CI, and one and three years post-CI. The total sample was composed of 40 participants (40% of men), with a mean age of 71 years. Results Speech recognition and the overall health-related quality of life improved one year post-CI (p= 0.000), without correlation (ρ= 0.27), and with no difference three years post-CI. The hearing attribute (in the health-related quality of life instrument) improved one and three years post-CI (p= 0.000). The level of anxiety did not change one and three years post-CI. The level of depression improved one year post-CI (p= 0.036), and deteriorated three years post-CI (p= 0.031). Age, etiology, operated side, residual hearing and cognitive performance did not predict the outcome, but the female gender did significantly improve speech recognition compared with men (p= 0.009). Conclusion The CI significantly improved speech recognition, health-related quality of life and level of depression one year post-CI without mutual correlation, and women performed significantly better than men. There were no further improvements three years post-CI, apart from the hearing attribute.

Este artigo discute o desenvolvimento de uma abordagem com métodos mistos para o estudo da mobilidade diária das crianças. O estudo aqui apresentado combinou pesquisa etnográfica com a tecnologia de GPS (Global Positioning System) e um questionário interativo que as crianças completaram via telefone celular. Esta metodologia permitiu produzir uma compreensão mais ampla dos movimentos cotidianos das crianças por meio de um rico conjunto de dados, documentando as experiências subjetivas das crianças, as observações sistemáticas, o mapeamento e levantamento de dados. Conclui-se que o sucesso de uma pesquisa usando métodos mistos requer uma estreita cooperação através do diálogo interdisciplinar e engajamento mútuo e coordenação de atividades e perspectivas.

This article discusses the development of a mixed methods approach to the study of children's everyday mobility. The study presented here combined ethnographic fieldwork with GPS (Global Positioning System) technology and an interactive questionnaire that the children completed via mobile phone. This methodology permitted the researchers to generate a fuller understanding of children's everyday movements through the rich dataset documenting children's subjective experiences, systematic observations, mapping and survey data. We conclude that the success of mixed methods research requires close cooperation through interdisciplinary dialogue and mutual engagement in and coordination of activities and perspectives.

Cet article aborde l'élaboration d'une approche de méthodes mixtes pour l'étude de la mobilité quotidienne des enfants. L'étude présentée ici associe le terrain ethnographique avec la technologie du GPS (Global Positioning System) et un questionnaire interactif que les enfants ont rempli via téléphone portable. Cette méthodologie a permis de produire une compréhension plus complète des mouvements de la vie quotidienne des enfants à travers un riche ensemble de données qui a documenté les expériences subjectives des enfants, des observations systématiques, de la cartographie et des données de survey. On a conclu que le succès de la recherche sur les méthodes mixtes nécessite d'une coopération étroite entre le dialogue interdisciplinaire et l'engagement mutuel et la coordination des activités et les perspectives.
