Prevalence of socioemotional problems in deaf and hard of hearing children in Germany.

The German version of the Strengths and Difficulties Questionnaire (SDQ) was used in a study to examine its usefulness in diagnosing socioemotional problems of deaf and hard of hearing children. The SDQ parent version was completed by 213 mothers and 213 fathers. The factor structure and reliability were tested, and the prevalence rate of socioemotional problems determined and compared to the German standardization sample. The statistical data were uniformly satisfactory; thus, the SDQ can serve as a valid yet economical screening procedure to identify endangered children at an early age, and to refer them to more exact diagnosis and subsequent advice and therapy. This is very important, as the prevalence of socioemotional problems in the sample of deaf and hard of hearing children was clearly greater for almost all scores, a result that is nearly identical with findings from many other recent studies.
