Validation of a parent outcome questionnaire from pediatric cochlear implantation.
This paper analyzes the reliability and validity of a questionnaire designed by Archbold, Lutman, Gregory, O'Neil, and Nikolpoulos (2002) for the assessment of pediatric cochlear implantation. Parents of 61 youngsters (age range 5 to 16 years), who had the implant for at least 3 years, responded to the questionnaire and to an interview. The alpha reliability of the 11 questionnaire scales varied between .41 and .74. Content validity was assessed by comparison with parents' responses to an interview. In general, there was agreement between parents' concerns and views expressed in the interview and as assessed by the questionnaire. However, extra issues were identified in the interview, which suggest the need for increasing the breadth of the questionnaire. Criterion validity was assessed by identifying contrasting cases, with very low or very high scores in each scale, and analyzing the descriptions obtained in the interviews. For nine scales this analysis provided support for the validity of the questionnaire; two scales did not produce positive results. Correlations with interview scores were calculated for only four scales: two were positive and significant whereas two were not significant. A factor analysis of the questionnaire scales identified four components, interpreted as the child's functioning in social situations, attitudes to the process of implantation, support required in the long term, and effective use of the implant. Suggestions for further research and descriptive comments provided by parents are included.
