Summary

Using a randomized controlled trial, we are going to examine whether a training program that incorporates both auditory training and working memory training (AT-WMT) would generate significantly better results in communication and cognition than an auditory training program and a mindfulness training program (active-control). Participants are 120 older adults (40 per group) with untreated mild-to-moderate sensorineural hearing impairment .

Detailed description

There will be three training groups: the Auditory training (AT) group, the Auditory-working memory training (AT-WMT) group, and the control group (mindfulness training). All training programs are home-delivered, non-clinician-administered, and computer-based. That is, training will be self-paced and administered by the participants themselves at home using a computer. A software program (see Figure 2) has been created to facilitate the administration of the AT and AT-WMT. All training groups will spend one hour per day and five days per week for 4 weeks. Before the training, two baseline test sessions (T1 and T2, a maximum of one week apart) will be used to account for the test-retest effects. The same measurements will be administered again one day (T3) and three months (T4) after completion of the training.

Interventions

Type	Name	Description
BEHAVIORAL	Auditory-working memory training program	The AT-WMT program is comprised of 1,200 daily used sentences either created or selected from newspapers, books, TV programs and magazines by the research assistants. The sentences are political-, cultural-, and religious-neutral sentences. Each of them contains 10 words. Noise was recorded from the upper and lower decks of a bus, in a café, a Chinese restaurant, an MTR (the Mass Transit Railway) carriage, and from a street. During the training, the following two adaptive tasks will be administered simultaneously: repeating the sentences masked by noise (i.e., AT component) and recalling the first or the final two words of all sentences in a given sentence set (i.e., WMT component).
BEHAVIORAL	Auditory training program	During the training, an adaptive speech-in-noise perception task will be administered. Specifically, the sentences in a sentence set will be presented binaurally using a headphone at a level the listeners felt is comfortable. The trainees are expected to immediately repeat each noise-masked sentence after hearing it. If they cannot repeat the sentence, then the sound intensity of the noise will be automatically decreased (step size = 2 dB) until the sentence can be correctly repeated. If the sentence can be repeated at the first attempt, then the intensity of the noise will be automatically increased by 2 dB in the next sentence. To provide feedback, the targeted sentence will be replaced by an asterisk and only shown after clicking the sentence.
BEHAVIORAL	Mindfulness training program	Participants in this group will participate in a mindfulness training program using newlife.330 (Psychiatric Rehabilitation Association, 2018) which is a Cantonese online platform for self-guided mindfulness training.
