Using word clouds to reveal patients' perceptions about their arthritis.

Objective: Patients' perceptions about their illness have the power to influence health outcomes. However, existing illness belief measures can be burdensome. Using word clouds to illustrate patients' experiences is potentially a novel solution, but research is lacking in this area. This study aimed to explore whether word clouds illustrate patients' perceptions about their illness and to determine commonalities and differences in experiences of rheumatic diseases.

Method: A cross-sectional study was conducted with 323 patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, or gout in New Zealand. Participants reported two words describing their inflammatory arthritis experience and completed the Brief Illness Perception Questionnaire. Word clouds were generated from participants' responses, and analysis of variance models were used to explore perceptions between groups.

Results: Eleven themes were identified, with each constituting a percentage of total word occurrence and weighting in word clouds. Symptom/sensation was the most prominent theme across all conditions (35%-61%), followed by affect/emotional experience (16%-25%). Theme prevalence varied across word clouds for each condition. Social impact was more prevalent for gout, and burden/intrusion was more prominent for ankylosing spondylitis. Functioning was less prevalent in the gout word cloud than in other conditions. There was moderate overlap between word cloud themes and illness perception domains. Word clouds uniquely identified themes related to burden/intrusion, functioning, opportunity, and social impact of illness.

Conclusions: This study supports using word clouds as a low-burden method of examining the experiences of patients with inflammatory arthritis and could be tested with other patient groups. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
