Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The proposed research is looking to improve hearing aid usage by using a self-affirmation intervention which lowers the threat of participants' ageing anxiety. The target of lowering participants' ageing anxiety to improve hearing aid use is because there is a stigma of hearing aids making people seem old and this stigma can make individuals resistant to wearing their hearing aids as they do not want to be seen in this light.
The current proposed research is an extension of a pilot study that was conducted in 2016 which found that a self-affirmation intervention may be useful in improving individuals' hearing aid usage. They randomly allocated 50 first-time hearing aid users either to a group that undertook a self-affirming exercise (e.g., "If I feel threatened or anxious, then I will think about the things I value about myself") or to a no-intervention control group. Consistent with the idea that self-affirmation helps people deal with threat, first-time hearing aid users reported significantly lower anxieties about ageing after self-affirming. Moreover, according to the data usage downloaded from their hearing aids (data-logging), the self-affirming group were found to have worn their hearing aids an average of two hours per day longer than the control group. Due to the limited number of participants, the effects of the intervention were not statistically significant. Nevertheless, the low cost and high potential public health "reach" alongside the effect size of d = 0.43 indicates that the intervention shows promise.
The main aim of this research is to re-test the self-affirmation intervention from the previous pilot study with a sufficiently large enough sample to answer the following "Does a self-affirmation intervention improve participant's hearing aid usage when compared to participants in the control group?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All prospective participants will be required to give written consent before being assigned to the study and those unable to do this will not be included. After consent is given participants will be allocated to either the intervention group or the control group. Procedure of the proposed study is as follows:
1. Each participant will be randomly assigned to either the control group or the intervention group. Blinding of both the participant and the researcher with regards to which group the participant has been assigned to will be achieved by all questionnaires being placed in opaque envelopes which will have a number printed on the front of the envelope. The numbers from the envelope will be placed in a computerised list generator and an order list of how they are to be administered will be produced. Alternatively participants can go online and the platform will randomly assign them to either the intervention or the control questionnaire.
2. Participants in both groups fill in a questionnaire which contain the following Scales: The Anxiety toward Ageing Scale (AAS), The Attitudes Toward Loss of Hearing Questionnaire (ATLH) and The Glasgow Benefit Hearing Aid Scale (GBHA) as well as a self-report question on their daily hearing aid use. The intervention group also undertake a self-affirmation exercise which is placed at the end of the questionnaire. This is expected to take 20-30 minutes.
3. Participants return 10 weeks later (post) and have their hearing aid usage downloaded (hours per day the aids were worn) from their hearing aids by an audiologist before subsequently filling in another questionnaire which again contains the AAS, ATLH, GBHA and a self- report question on their daily hearing aid use. This is expected to take 30-40 minutes.
3A: If it is not possible for the participant to come back for a follow up appointment the second questionnaire will be sent out postal to the participants address or an email with a hyperlink to the follow up questionnaire online will be sent to participants who previously completed the first questionnaire online.
4: Six months later participants are contacted via email ( hyperlink) or post to fill in an optional questionnaire containing the AAS, ATLH, GBHA and a self-report question on their daily hearing aid use which they send back to the researcher. This should take 20-30 minutes. If participants receive the follow up questionnaire through the post the shopping voucher will also be enclosed. Online participants will also receive their shopping voucher through the post.
5: A debrief form will be sent out via e-mail or post by the principal researcher 3 weeks after the follow up questionnaire was returned or alternatively if they decide to not to complete the follow up questionnaire the debrief will be sent 4 weeks after the initial questionnaire request was sent.
A G-power analysis was conducted to detect a small-moderate effect size (Cohen's D of 0.35) with 80% power at the 5% significance level which indicated that a sample of 260 participants (130 per group) would be required. This study will attempt to recruit 400 based on a similar pilot study having a 34% attrition rate. The data collection phase will continue until 260 participants have completed the 10 week follow up.
The study design is a mixed Design: Between-participants factor is condition (control vs intervention). Within-participants factor is time (pre-intervention vs post intervention (10-week) vs exit (6 month after post ). We will use a series of 2 (Intervention, control) x 3 ( pre-intervention, post intervention and exit) repeated ANOVA to assess to assess the outcome measures. If a small-moderate effect size (Cohen's d = 0.35) is found on any of the principle and secondary measures, then the Hayes PROCESS macro will be used to examine the possible mediating effects of the intervention on participants' hearing aid usage. If data is missing at the 10-week follow up the participant concerned will be excluded from the analysis at this point. The present study also has a longitudinal element and attrition at 6 months is expected. Any missing data will be addressed by using the "last observation carried forward technique".
All data such as contact details and ethnicity will be pseudonymised and kept in a separate, password protected file, in a restricted access folder on a secure University server. All paper copies of contact details and questionnaire data will be secured in Manchester University in a locked filing cabinet. Only the study team and regulatory monitoring and auditing authorities from the University of Manchester will have access to this data.
All the questionnaire data will be anonymised and kept in a separate, password protected file, in a restricted access folder on a secure University server. Only the study team and regulatory monitoring and auditing authorities from the University of Manchester will have access to this data.
The physical personal data copies will be kept until completion of the study then will be destroyed in accordance with University of Manchester regulations. All consent forms and questionnaire data are deemed as essential and this will be kept for 5 years to comply with University of Manchester regulations.
The current study will go through ethics approval with the National Health Service, Health Research Authority in the UK before it will be allowed to proceed. The study has already been through a preliminary ethics review at the University of Manchester.
