“…This study demonstrated that the DEQS-Th questionnaire has a criterion (concurrent) validity with the OSDI, consistent with a related study by Inomata et al that demonstrated a strong correlation between the DEQS and the Japanese version of OSDI (J-OSDI) scores. They found that the J-OSDI scores tended to be higher than the DEQS (31.6 vs. 27.6) which was in accordance with our study [ 34 ].…”

Dry eye disease (DED) is a common and growing eye problem worldwide. Chronic DED symptoms can, subsequently, affect the patients’ quality of life (QOL). This prospective cross-sectional study aimed to assess the reliability, validity, and responsiveness of the Thai version of the Dry Eye-Related Quality-of-Life Score (DEQS-Th) questionnaire and to evaluate its accuracy in DED screening. Psychometric validation was conducted on DED participants. All participants completed the DEQS-Th and other measurements including the Ocular Surface Disease Index (OSDI) and the 5-level EQ-5D (EQ-5D-5L). Internal consistency, concurrent validity, convergent, and discriminant validity were evaluated. The standardized response mean (SRM) was used to evaluate the responsiveness of the DEQS-Th. The optimal cut-off score of DEQS-Th for DED screening was assessed. Among 100 participants with a mean age of 50.9 ± 14.4 years, and 89.0% female, the internal consistency of the DEQS-Th was excellent (Cronbach’s alpha: 0.80–0.92). The test-retest intraclass correlation was 0.82–0.92. It showed concurrent validity with the OSDI (r = 0.694, p < .001) and EQ-5D-5L index scores (r = -0.578, p < .001). DED is suspected if the DEQS-Th score ≥ 18.33 (AUC = 0.897, sensitivity 90.0%, specificity 76.7%) or its Short Form score ≥ 3 (AUC 0.857, sensitivity 93.0%, specificity 63.3%). The SRM of the symptom subscale of DEQS-Th was 0.82, indicating relatively large responsiveness, whereas the impact on daily life subscale and the summary score was small. In conclusion, the DEQS-Th is valid and reliable for evaluating the multifaceted effects of DED on a patient’s QOL. It can be useful for primary assessment and monitoring of DED in routine clinical practice.

“…However, the DEQS may be cumbersome for respondants because it requires responding to up to 30 questions, compared with the 12 questions in the OSDI. Nevertheless, a recent study showed that the OSDI and the DEQS are significantly correlated, with negligible score differences [ 22 ]. This evidence affirms the use of the DEQS-Th as a valid method to assess subjective dry eye symptoms.…”

Background This study aimed to develop a Thai version of the Dry Eye–Related Quality-of-Life Score (DEQS-Th) questionnaire and evaluate its validity, reliability, and feasibility among Thai participants. Methods The DEQS-Th, a 15-item self-report measuring dry eye and its impact on quality of life (QOL) was developed based on the DEQS. The questionnaire was divided into two subscales: Bothersome Ocular Symptoms (six questions), and Impact on Daily Life (nine questions). It employed a 5-point Likert scale, addressing on both the frequency and the degree of symptoms. Backward and forward and cultural adaptation process translation methods were employed. Thirty healthy participants were enrolled to evaluate the feasibility of the DEQS-Th in terms of difficulty and convenience. Reliability was assessed using internal consistency determined by Cronbach’s alpha, with values > 0.7 considered acceptable. Convergent validity was determined by the correlation between DEQS-Th and overall health status. Confirmatory factor analysis was conducted for its factor structure. Results The participants’ mean age was 38.6 ± 12.9 years, and 23 (76.7%) were females. The mean time to complete the questionnaire was 9.3 ± 2.7 min. The Cronbach’s alpha of the ocular symptoms subscale, impact on QOL subscale, and summary score on frequency and degree were 0.80 and 0.70, 0.89 and 0.89, and 0.90 and 0.89, respectively. The overall health status significantly correlated with the summary score (r = 0.564, p = .001), subscale ocular symptoms (r = 0.594, p = .001), and impact on QOL scores (r = 0.626, p < .001) of the DEQS-Th, respectively. A one-factor model fitted the data the best for both the ocular symptoms subscale (CFI = 1.000, TLI = 1.000, RMSEA = 0.000) and the impact on QOL subscale (CFI = 0.998, TLI = 0.997, RMSEA = 0.053). Conclusion When tested among normal participants, the DEQS-Th is a valid and reliable measurement for dry eye symptoms and impact on QOL.

“…The internal consistency of the app-based JACQLQ was assessed using Cronbach alpha coefficient, with an alpha score of >.70 considered acceptable [ 20 ]. Concurrent validity was assessed by calculating the correlations (Pearson coefficient) and mean differences (Bland-Altman analysis) [ 15 , 21 ].…”

Background Hay fever is a highly prevalent, heterogenous, and multifactorial disease. Patients may benefit from longitudinal assessments using mobile health (mHealth) principles. We have previously attempted to establish an effective mHealth platform for patients with hay fever through AllerSearch, our in-house smartphone app that assesses electronic patient-reported outcomes through a questionnaire on hay fever and provides evidence-based advice. To be used by the public, an investigation on its reliability and validity is necessary. Objective The aim of this paper is to assess the reliability and validity of subjective symptom data on hay fever collected through our app, AllerSearch. Methods This study used a prospective observational design. The participants were patients aged ≥20 years recruited from a single university hospital between June 2, 2021, and January 26, 2022. We excluded patients who could not use smartphones as well as those with incomplete data records and outlier data. All participants answered the Japanese Allergic Conjunctival Disease Standard Quality of Life Questionnaire (JACQLQ), first in the paper-and-pencil format and subsequently on AllerSearch on the same day. The JACQLQ comprises the following three domains: Domain I, with 9 items on ocular or nasal symptoms; Domain II, with 17 items on daily activity and psychological well-being; and Domain III, with 3 items on overall condition by face score. The concordance rate of each domain between the 2 platforms was calculated. The internal consistency of Domains I and II of the 2 platforms was assessed using Cronbach alpha coefficients, the concurrent validity of Domains I and II was assessed by calculating Pearson correlation coefficients, and the mean differences between the 2 platforms were assessed using Bland-Altman analysis. Results In total, 22 participants were recruited; the data of 20 (91%) participants were analyzed. The average age was 65.4 (SD 12.8) years, and 80% (16/20) of the participants were women. The concordance rate of Domains I, II, and III between the paper-based and app-based JACQLQ was 0.78, 0.85, and 0.90, respectively. The internal consistency of Domains I and II between the 2 platforms was satisfactory (Cronbach alpha of .964 and .919, respectively). Pearson correlation analysis yielded a significant positive correlation between Domains I and II across the 2 platforms (r=0.920 and r=0.968, respectively). The mean difference in Domains I and II between the 2 platforms was 3.35 units (95% limits of agreement: –6.51 to 13.2). Conclusions Our findings indicate that AllerSearch is a valid and reliable tool for the collection of electronic patient-reported outcomes to assess hay fever, contributing to the advantages of the mHealth platform.
