title: Test-retest reliability of a shortened version of the hearing aid performance inventory.
abstract: Sixty-four elderly hearing aid users completed a shortened version of the Hearing Aid Performance Inventory (HAPI) on two occasions, separated by 1 to 2 months. The test-retest correlation was .80 for the overall scale and ranged from .70 to .85 for the four factor ratings. The mean overall rating and the mean ratings on each of the four factors demonstrated nonsignificant shifts from test to retest. The 95 percent confidence intervals for the overall scale and for each factor are presented for interpretation of differences in HAPI ratings between aided conditions.
