Subclaims¶

q3 i2 In adult CI users, the number of items answered correctly on the 48-item RPM significantly correlated with sentence recognition measures (r = .35 to .47). → Mattingly Jameson K MD 2018

Bivariate Pearson correlation analysis in 39 post-lingually deafened adults with CIs, reported in Results (Table 3). RPM items correct correlated with Harvard Standard sentences (% words correct r = .35; whole sentences r = .46) and PRESTO sentences (% words r = .41; whole sentences r = .47), i.e., "positively correlated with speech recognition measures."

"In both groups of participants, RPM scores (items correct) were positively correlated with speech recognition measures."

Discussion¶

Related Claims¶

• An abbreviated 12-item RPM subset predicts sentence recognition in CI users with comparable validity to the full 48-item test — a narrower finding that bears on this claim
• CI users answered fewer RPM items correctly than normal-hearing controls, though both groups attempted similar numbers of items — related
• Demographic and audiologic factors (age, duration of hearing loss, age at onset, residual hearing) were not significantly correlated with speech recognition in CI users — related
• Nonverbal reasoning scores also correlate with degraded (noise-vocoded) sentence recognition in age-matched normal-hearing listeners — related
• The 12-item RPM subset similarly predicts degraded sentence recognition in normal-hearing controls, replicating the CI finding — related
