NCT06362213 | Not Yet Recruiting DMC

• 1 other identifier: NL76924.029.22
• Study Type: observational
• Target: 300
• Locations: 1 country
• Sites: 1

Brief Summary

The goal of this observational study is to explore difficulties in information access, mobility, communication and fatigue in people with combined vision and hearing impairments. The main question it aims to answer is: • What influence do varying severities of vision and hearing loss have on information access, mobility, communication and fatigue. Participants will fill out questionnaires and the researchers will measure their vision and hearing functions.

Conditions

Dual Sensory Impairment of Vision and Hearing

Keywords

information access; mobility; communication; fatigue; visual acuity; contrast sensitivity; visual field; hearing threshold; speech understanding in noise; speech understanding in silence; directional hearing

Outcome Measures

Primary Outcomes (4)

• information access

  Access to information will be measured with the Dutch ICF Activity Inventory (subscales 'Watching TV', 'Using a computer' and 'Using a telephone'). These subscales consist of 11, 13 and 5 items, respectively (29 items in total). All items are scored on a 5-point likert scale.

• mobility

  Mobility will be measured with the Dutch ICF Activity Inventory (subscales 'Mobility outdoors (walking)' and 'Using public transportation'). These subscales consist of 16 and 15 items, respectively (31 items in total). All items are scored on a 5-point likert scale. Secondly, the Spatial Localization Questionnaire20 will be used, consisting of 35 items, describing common scenarios. The following question structure is provided under each of the scenarios: Can you complete this task solely with your current vision? If yes, how difficult is it? (rated on a 5-point likert scale) Can you complete this task solely with your current hearing? If yes, how difficult is it? (rated on a 5-point likert scale) Would you primarily rely on your vision or hearing for this task? Do you use the other sense for this task at all?

• communication

  Communication will be measured with the Speech, Spatial and Qualities of Hearing Scale (speech subscale). This subscale consists of 14 items and is scored on an 11-point visual analog scale.

  1 day

• fatigue

  Fatigue will be measured with the Dutch ICF Activity Inventory (feeling fit subscale). This subscale consists of 9 items, scored on a 5-point likert scale. Secondly, the Fatigue Assessment Scale will be used, consisting of 10 items, scored on a 5-point likert scale.
