    A hand exercise mobile app for people with rheumatoid arthritis in Turkey: design, development and usability study
    (SPRINGER HEIDELBERG, 2021) TONGA, EDA; Tonga, Eda; Williamson, Esther; Srikesavan, Cynthia; Ozen, Tugce; Saritas, Fatih; Lamb, Sarah E.
    To design and develop a smartphone application for a structured hand exercise programme for patients with rheumatoid arthritis (RA) in Turkey and to test its usability. We followed a two-stage process: (1) Design and Development and (2) Usability testing. In stage 1, we used a qualitative user-centered design approach. We conducted a focus group (8 therapists and people with RA) to discuss the content, features and design to produce a prototype of the application. In a second focus group session, the participants tested the prototype, provided feedback and further revisions were made. In stage 2, 17 participants with RA used the app for 4 to 6 weeks. The System Usability Scale and the adapted Usability, Satisfaction and Ease to Use Questionnaires were used to measure usability, ease of use. Semi-structured interviews were conducted to explore user experiences with the application with 17 participants. In stage 1, the following themes were identified from the focus groups (a) login techniques (b) self-monitoring (c) exercises, (d) exercise diary, (e) information, (f) behavioral change and encouragement (g) exercise adherence. In stage 2, 3 themes were determined from interviews: (a) learning and accuracy, (b) ease of use, (c) motivation and adherence. USE and SUS scores indicated that users reported a high level of usability, satisfaction and ease of use. A mobile app for hand exercise for people with RA was developed using a mixed-method and iterative design. Participants perceived the mobile app as easy to use with high levels of satisfaction.

    Development and reliability of a Turkish version of the Short Form-Joint Protection Behavior Assessment (JPBA-S)
    (HANLEY & BELFUS-ELSEVIER INC, 2016) TONGA, EDA; Tonga, Eda; Uysal, Songul Atasavun; Karayazgan, Sedef; Hayran, Mutlu; Duger, Tulin
    Study design: Clinical measurement. Purpose: To adapt the original JPBA-S to a Turkish version (TUR-JPBA-S) and to investigate its reliability in assessing patients with rheumatoid arthritis (RA). Methods: Twenty-two participants with RA and 21 healthy people were videotaped while performing tasks listed in the TUR-JPBA-S. Two raters scored the video recordings for to evaluate inter-rater reliability. One rater re-analyzed the recordings at a different time point for intra-rater reliability. Participants with RA were asked to perform the same tasks after three to four weeks which was also recorded to evaluate test-retest reliability. Results: Internal consistency (Cronbach's alpha value) was found to be high (0.89) for participants with RA. Our results demonstrate excellent intra-rater (ICC: 0.99, SEM 1.2) inter-rater (ICC: 0.99, SEM 1.7) reliability, apart from excellent test-retest reliability (ICC: 0.96). Conclusion: The TUR-JPBA-S is a valid and reliable instrument for assessing JP behavior in patients with RA in Turkey. (C) 2016 Hanley & Belfus, an imprint of Elsevier Inc. All rights reserved.
