Objective: The most effective modality for presbycusis is using hearing aids. However, the rate of adoption and use of hearing aids among the elderly is not in line with the expectations. This review investigates the current evidence to identify factors affecting the adoption and use of hearing aids among the elderly with hearing loss. Design: This is a systematic review whose sample includes English articles published in peer-reviewed journals from January 2015 to October 2020. The search was conducted in PubMed, Web of Science, ProQuest, and Scopus electronic databases. Study selection, data extraction, and quality assessments were performed by two independent reviewers. Results: In the 22 studies included in this review, a number of factors, including demographic status (economic status and level of education), auditory factors (hearing loss severity, presence of tinnitus, and the sound quality of hearing aids), attitudinal and psychosocial factors (self-perceived hearing problems, perceived self-efficacy, perceived benefit, support from significant others, and extrovert and ambivert personality types) were identified as variables potentially impacting the adoption and use of hearing aids. Conclusion: The results show that demographic, attitudinal, and psychosocial factors, as well as auditory factors, play an influential role in the adoption and use rate of hearing aids among older populations suffering from hearing loss. Therefore, it is necessary to consider these factors in order to formulate hearing healthcare policies and adopt targeted and appropriate interventions in the process of prescribing, adjusting, and evaluating hearing aids. PROSPERO registration: The protocol of this systematic review was published in the International prospective register of systematic reviews (PROSPERO) with registration number: CRD42021227684 (https://www.crd.york.ac.uk/prospero/display_ record.php?ID=CRD42021227684)

Background & Aim: Continuous use of hearing aid is an effective way of managing hearing impairment consequences in older adults. The present study seeks to evaluate the factor determining the continuance intention to use hearing aids in older adults. Methods: The present cross-sectional study was carried out in 2021. Technology Post-Acceptance Model (PAM) theoretical framework was used to develop a model for continuance intention to use hearing aids. A total of 300 hearing aid users aged 60 or above in Tehran selected through the randomized stratified method completed the self-assessment questionnaires used in the study. The model was tested using the SEM method (path analysis using the maximum likelihood estimate technique) in AMOS V.24 software. Results: The participants had a mean age of 71.38 (SD=8). 50.7% of the participants were female and 49.3% were male. The mean overall continuance intention to use hearing aids was calculated to be 10.14(2.91), and 63.3% of the participants were revealed to have success in the actual use of their hearing aids. Path analysis results indicated that continuance intention to use hearing aids was positively and significantly influenced by the main variables of the study including actual use of hearing aids, self-perceived benefit, satisfaction, confirmation, self-efficacy in using hearing aids, extroversion personality trait, self-reported hearing handicap, and perceived social support. Moreover, regression analysis revealed that the independent variables explained 60% of the variation in continuance intention to use hearing aids and 69% of actual use of hearing aids. The values of fitness indices were CMIN = 2.52, RMSEA = 0.07, IFI = 0.92 and CFI = 0.92, which suggests that the model proposed in the present study is a good fit. Conclusion: The main results of the present study help hearing care providers develop a better understanding of older users to design effective interventions and strategies and make sure of the patients' continuance intention to use hearing aids.

Objective: The purpose of this study was to investigate the relationship between organizational citizenship behavior, organizational commitment and its dimensions on the Welfare staff in Tehran 2013. Materials & Methods: In this cross - sectional study, one hundred eight staff of Tehran Welfare were selected by random sample, and the sample size of the previous studies. Data were collected using two standard questionnaires OCB, and Organizational Commitment, which includes the three dimensions, affective commitment, normative commitment and continuance commitment and analyzed by statistical methods such as: Pearson correlation coefficient and ANOVA. Results: The finding showed Between OCB and organizational commitment there was significant and positive correlation (P&le0.01, r=0.325). Also the dimensions of organizational commitment: affective commitment and normative commitment have a significant positive relationship with OCB, but not significant relationship OCB with a continuous commitment. ANOVA results showed that the average OCB in age, type of employment and employee experience is different. And Continuous commitment in hiring employees is different and emotional commitment in Background employees is different. Conclusion: Based on the findings we conclude that the enhancement of organizational citizenship behavior, organizational commitment and staff of Tehran can be increased.
