Although their clinical problems are amenable for the clinical diagnosis, their Introduction day-to-day problems for having to live with the disease are mostly unexplored. This study Retinitis pigmentosa is a group of inherited aims to explore and understand the issues retinal disorders that affects the photoreceptors and impact of people with RP on quality of and the retinal pigmentary epithelium.1 In some life (QoL). disorders the rods are affected first and the cones Methods A qualitative research later (termed rod-cone dystrophy) or the reverse methodology to facilitate the understanding (cone–rod dystrophy).

Even though these problems are identified key threads. These key threads were then re-assessed by clinically, limited research has been conducted to the authors to come to a decision whether they qualify to understand the impact on day-to-day life of people with form a theme. Any discrepancies between the authors RP from their perspectives. A well-conducted qualitative were resolved by discussion. New or improved themes study is essential to understand the patient’s experience of that emerged from later transcripts were incorporated living with RP. Hence, the aim of this study was to into the coding hierarchy, and earlier transcripts were explore the issues and impact of people with RP on QoL. updated to reflect the modification. The computer program QSR NVivo 10 (QSR International Pty Ltd) was Materials and methods used to code the transcripts systematically. Twenty-three participants with RP were recruited through a nonprobability, convenience sampling Rigor techniques. Participants were recruited from the Royal Several identified strategies were used to enhance the Society for the Blind (Adelaide) and Retina Australia trustworthiness of this study including credibility, Society (Queensland, Western Australia, Victoria, New transferability, dependability, and confirmability. fl South Wales, and Canberra) through emails and yers. Credibility was achieved through adoption of systematic, Participants who responded to the email request and the in-depth field work and triangulation of time and space fl yers were sent out a research pack consisting of an (various times of the day, week, and year were used in the invitation letter, participant information sheet, consent collection of the data and use of multi-sites for participant form and demographic form in the post. Upon receiving recruitments). Transferability was achieved through the consent form, participants were contacted through description of the clinical context of the study and telephone to organise a date and time for an interview. description of the demographics of the participants. A semi-structured interview guide was developed from Dependability was achieved through in-depth description existing literature and expert consultation and it was of the methodology and confirmability was achieved validated by a panel of experts. The interviews were through the recognition of shortcomings in study’s carried out over the telephone. All the interviews method and their potential effects. occurred between August 2014 and June 2015. All interviews were audio recorded and transcribed. Interviews were carried out till thematic saturation (no Results additional new information arising) was obtained. A total of 23 interviews were conducted (mean age = 55.6 An ethical approval was obtained from the Southern years (SD = 14.3); range = 28 to 81 years; females, 14). Adelaide Clinical Human Research Ethics Committee and Two-thirds of the participants were above the age of 50 the corresponding ethics committees at health care facilities and the study adheres to the Tenets of years and all the participants had bilateral disease Declaration of Helsinki. (Table 1). The mean age of onset of the disease was 18.8 years (SD = 11.8) and the mean duration of the disease was 38.9 years (SD = 14.7). We identified five major QoL Data analysis themes: (1) struggle to perform important day-to-day We used an inductive approach where the content of the tasks (activity limitation); (2) concerns about disease data directed the coding and the theme development progression disease outcome and personal safety (health (data-driven).16 Nodes (words or phrases) to code text concerns); (3) facing a lot of emotional and psychological segments were generated after scan reading individual challenges (emotional well-being); (4) experiencing a transcripts.
