Means for the PHABavds outcome measure for each of the six subgroups evaluated in the 3 × 2 factorial analysis. Unaided (black bars) and aided (red bars) PHAPavds scores are provided, as well as the difference between these two scores, PHABavds (green bars). Data are for N = 154, with 53 audiology best practices (AB), 51 consumer decides/over-the-counter (CD), and 50 placebo device (P) participants included. Purchase-price subgroups are “red” (reduced; $600) and “typ” (typical; $3,600). Error bar = +1 standard error; PHABavds = difference between aided and unaided scores of PHAPavds (Profile of Hearing Aid Performance, average of Aversiveness of Sound and Distorted Sound subscales).
