TL;DR

The study evaluated the retest stability of the Communication Profile for the Hearing Impaired by administering pretests to 101 active‑duty military personnel and retesting them 6 to 40 weeks later, then using retest‑test difference distributions to set criteria for significant score changes. Results showed only modest declines in five of 25 CPHI scales (±0.20), with retest correlations ranging from 0.58 to 0.78 for communication environment, strategies, and personal adjustment, while communication performance and importance were less stable (0.28–0.54) and correlations varied by rank but were similar across short and long intervals.

Abstract

Retest stability of the Communication Profile for the Hearing Impaired (CPHI) was assessed in a sample of 101 active-duty military personnel who attended the Aural Rehabilitation Program at Walter Reed Army Medical Center. Pretests were administered by referring audiologists; retests were administered from 6 to 40 weeks later, at the beginning of the rehabilitation program. Mean scores on 5 of the 25 scales of the CPHI decreased significantly (p < 0.01) over time, but the changes were small in magnitude (± - 0.20). Distributions of retest-test differences were used to establish criteria for inferring significant improvement in scores over time. Retest correlations for scales in the communication environment, communication strategies, and personal adjustment areas ranged from 0.58 to 0.78. Communication performance and communication importance were less stable (± = 0.28 to 0.54). Retest correlations were comparable for short versus long retest intervals, but varied as a function of military rank. Implications of the results for clinical use of the CPHI are discussed.
