Show moreObjectives: To compare the quality of life (QoL) of children with hearing loss (HL) and children with normal hearing (NH) and to examine how the QoL of children with HL changes over time, considering language skills, type of hearing device, degree of HL, and type of education.Methods and materials: This longitudinal study included 62 children with HL and their parents. Developmental outcome data were collected at two time points, when the mean ages of the children were 4 and 11 years. The Pediatric Quality of Life (PedsQL (TM)) questionnaire, which includes assessments of Physical, Emotional, Social, and School functioning, was completed by parents at both time points and by the children with HL at the second time point. Receptive and expressive language skills at 4 years were assessed by the Reynell Developmental Language Scale. Results were compared with a Dutch normative sample.Results: The QoL of children with HL was similar to that of children with NH at both time points on two of the four QoL scales, Emotional and Physical functioning. On the other two scales, Social and School functioning, children with HL who attended special education and children who switched to mainstream education showed lower scores than children with HL who were consistently in mainstream education and lower scores than children with NH. The School QoL of children with HL decreased over time, as did the School QoL of children with NH. Social QoL of children with cochlear implants decreased over time, but this was not the case in children with hearing aids. Language skills and the degree of HL did not clinically improve the QoL over time of preschool children with HL.Conclusions: The QoL of children with HL in mainstream education and the Physical and Emotional QoL of all children with HL were satisfactory. It is essential to develop specific guidance regarding school activities for children with HL in special education and for children with HL who switch to mainstream education in order to increase their social QoL.

Show moreThe aim of this thesis was to study the link between hearing loss, language skills, and social functioning in deaf and hard of hearing (DHH) children. Sufficient language skills are an essential prerequisite to develop appropriate communication skills, in order to join in conversations with others. Both their hearing loss and their diminished communication skills prevent DHH children from learning by observing their surroundings (incidental learning). As a result, DHH children showed more difficulty in understanding others’ thoughts and wishes (Theory of Mind or ToM). DHH teenagers reported to have difficulties with understanding others’ emotions and showed lower levels of prosocial behavior. Higher communication skills, but not language skills, were related to better ToM development and higher empathic abilities. Second, the role of early identification and intervention of hearing loss on the social-emotional development of DHH children was studied. This was illustrated in a longitudinal study showing that early cochlear implantation resulted in higher language and communication skills. In turn, these improved skills prevented the development of early signs of psychopathology. To conclude, this thesis shows that in order to stimulate the social-emotional development of DHH children, their opportunities for incidental learning have to be increased. Show less
