ItemPsychologically Informed Practice in Hearing Healthcare: Perspectives and Needs of Clients and Audiologists( 2022)For many people, the sense of hearing provides a connection with others and the world around them. Losing one’s hearing can have a deleterious impact on many psychological and social aspects of life. Hearing loss can compromise psychological wellbeing, resulting in an increase in loneliness or reduced self-esteem, and it can also increase the odds of experiencing psychological symptoms, such as depression and anxiety. Given this association, audiologists are likely to encounter clients with psychological concerns on a regular basis. Understanding how these clients experience audiological rehabilitation may be an important way for audiologists to provide relevant and optimal services. Psychological factors, including mental health and illness, can also significantly influence the initiation, adherence, and success of audiological rehabilitation. Despite this, psychological factors are not adequately considered within hearing healthcare, so the recommended approach of person-centred care may need to be further extended to better address these factors. Psychologically informed practice (PIP) may provide a suitable framework that can be used to extend upon person-centred care, especially for clients with comorbid psychological symptoms. A PIP framework recognises the role of psychological factors in chronic health conditions and addresses these using psychological theories and frameworks. PIP has shown success in other rehabilitation settings and may therefore provide benefits within hearing healthcare. The aim of this thesis was therefore to explore the nature of mental illness, mental health, and psychological symptoms within audiological rehabilitation, from the perspective of clients and audiologists, and to provide a foundation of support for the implementation of PIP into hearing healthcare. Four studies were conducted to achieve the aims of this thesis. The first study included in-depth, semi-structured qualitative interviews to understand the experience of hearing loss and audiological rehabilitation for older adults with comorbid psychological symptoms. A novel theme found in this study was the bi-directional and cumulative relationship between hearing loss and psychological symptoms. Given the relationship between hearing loss and psychological symptoms, the second study included a systematic review and meta-analysis to determine the effect of interventions targeted at hearing loss on psychological symptom outcomes in adult clients. The meta-analysis showed that hearing aids, cochlear implants, and communication and education programs resulted in a small decrease in depression and anxiety symptoms. A mixed-method survey of audiologists working in adult audiological rehabilitation in Australia was then conducted to understand the nature of client-audiologist discussions about client mental health within audiological rehabilitation. This study found that audiologists occasionally discuss mental health, and clients are more likely than clinicians to initiate these conversations. The final study aimed to determine the barriers and facilitators to audiologists discussing and addressing client mental health, and to determine audiologists’ preparedness and willingness to implement aspects of PIP in audiological rehabilitation. Audiologists were generally motivated to incorporate PIP into audiological rehabilitation; however, a lack of knowledge about mental health and organisational barriers, such as time and resources, would need to be overcome. Overall, the studies in this thesis provide an understanding of how psychological symptoms are experienced, recognised, discussed, and addressed within audiological rehabilitation and suggested that the current way of delivering audiological rehabilitation is insufficient to achieve optimal outcomes for clients with psychological symptoms. These studies form an evidence-based foundation and rationale for the implementation of PIP within hearing healthcare.
