Psychological Predictors of Pediatric Cochlear Implant Use and Benefit

Outcomes and Achievement of Students Who Grew Up with Access to Cochlear Implants

“…Eleven percent of this cohort became nonusers within the first 3 years after implantation, whereas 88% remained consistent users up until their teen years. Knutson et al 15 reported that identified unreliable use within the first years after implantation was not attributable to limited audiologic benefit. In the current study, however, the group of individuals who became inconsistent users after 7 years of consistent use demonstrated significantly lower perceptual testing results.…”

Behavioral Assessment of Prelingually Deaf Children Before Cochlear Implantation

“…However, three limitations make their results somewhat difficult to interpret. First, Knutson et al 8 did not report descriptive findings from the individual psychological measures obtained from children in their study. We do not know, for instance, how many children showed evidence of behavioral problems, nor do we know how performance on these measures compared with normative data.…”

“…Knutson et al 8 reported audiological results from a study of 69 PLD children with cochlear implants who received preimplant psychological testing. Standardized caregiver behavioral reports and nonverbal intelligence tests were administered before CI surgery, and scores were correlated with a range of audiological outcome measures obtained at 1‐year intervals after implantation.…”

Exploration of the cognitive and behavioural consequences of paediatric cochlear implantation

“…The most significant work identified is that by Knutson et al (2000b) who reported that children who were regular implant users had significantly fewer externalizing behaviour problems than 'unreliable' and non-users. The authors found strong negative correlations between externalizing behaviour problems (for example temper tantrums, demanding attention, uncooperative behaviour) and speech perception scores after 36 months of implant use.…”
