Mental health problems in deaf and severely hard of hearing children and adolescents : findings on prevalence, pathogenesis and clinical complexities, and implications for prevention, diagnosis and intervention

The aim of this thesis is to expand the knowledge of mental health problems with deaf and severely hard of hearing children and adolescents in the following domains: 1. The prevalence of mental health problems; 2. Specific intra- and interpersonal aspects of pathogenesis; 3. characteristics of the hearing impaired population with severe mental health problems. The rate of mental health problems, especially of emotional problems, was increased in deaf adolescents of normal intelligence compared with the general population. However, findings from the studies described in this thesis support the view that it is not deafness in itself which contributes to mental health problems but rather deafness in conjunction with physical health problems, communication problems, and adverse living conditions. For example, stress-inducing deafness-related characteristics such as an acquired cause of deafness moderated the associati on between low self-esteem and emotional disorder in deaf adolescents. Comparing hearing and hearing impaired children referred to a mental health service over a period of 15 years, more disabling physical health conditions, more intellectual impairment and more environmental distress were found with hearing impaired children. The findings argue for the importance of early detection of problems and a multi-informant approach to the assessment of disorder
