Objective:
To evaluate an online version of the 25-item Hearing Handicap Inventory (HHI) in terms of reliability and potential effects of item order.
Design:
Participants completed a Danish translation of the HHI online. Two different item orders were compared: (1) the conventional order and (2) an experimental order where items were presented in blocks starting with the 10-item Hearing Handicap Inventory Screener (HHI-S). Internal consistency and test-retest reliability were also examined. Bland-Altman limits of agreement were calculated for different degrees of hearing-related well-being ("auditory wellness").
Study Sample:
Participants aged 50 and above with a wide range of hearing abilities (N = 194).
Results:
No effects of item order were found. The HHI and HHI-S both showed excellent internal consistency and good test-retest reliability. Bland-Altman limits of agreement broadened as auditory wellness worsened.
Conclusion:
HHI scores appear unaffected by the item order. The HHI-S can be extracted from the full HHI without changing the results. The test-retest reliability of the HHI varies with auditory wellness.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
