OBJECTIVES

This study aimed to evaluate the psychometric properties of the Tagalog version of the PsAQoL to assess its reliability and consistency.

METHODS

This is a prospective validation study involving 47 patients with PsA from June to August 2023. The
psychometric properties tested were internal consistency (Cronbach’s alpha coefficients), test-retest reliability, convergent validity (Spearman’s rank correlation), and known group validity (Mann-Whitney U Test or Kruskal- Wallis One-Way Analysis of Variance).

RESULTS

The PsAQoL on both week 0 and week 2 had Cronbach’s alpha coefficients of 0.926 indicating high
internal consistency. Test-retest reliability was 0.929, which demonstrates excellent reliability and low level of random measurement error. The PsAQoL scores highly correlated with the Health Assessment Questionnaire-Disability Index (r=0.754, pCONCLUSION

The Tagalog version of the PsAQoL demonstrates excellent psychometric properties and is recommended for monitoring of Tagalog-speaking patients with psoriatic arthritis in healthcare settings.

BACKGROUND: Keloid, a fibroproliferative skin disorder, requires accurate scar assessment. Comprehensive evaluation using a standardized instrument from both patient and observer perspectives is essential to capture its multidimensional impact. This study aimed to translate, culturally adapt, and validate the generic patient and observer scar assessment scale (POSAS) 3.0 into Indonesian for keloid assessment. METHODS: A cross-sectional design was adopted following the translation and cultural adaptation guidelines. The instrument was translated into Indonesian by certified translators and administered to 68 keloid patients and 62 dermatologists especially recruited from Pekanbaru and the surrounding areas. Content validity was assessed using the scale-level content validity index average (S-CVI/Ave), construct validity through exploratory factor analysis (EFA), internal consistency with Cronbach’s alpha, test-retest reliability using the intraclass correlation coefficient (ICC), and external validity by correlating the observer scar assessment scale (OSAS) with the modified Vancouver scar scale (mVSS). RESULTS : The Indonesian version of the generic POSAS 3.0 demonstrated strong psychometric properties. The S-CVI/Ave was 0.97. The EFA revealed 3 factors for the patient scar assessment scale and two for the OSAS, explaining 71.25% and 73.1% of the variance, respectively. Cronbach’s alpha was 0.79–0.90 and ICC was ≥0.83. External validity was confirmed by a strong correlation with the mVSS (Spearman’s rho = 0.82, p<0.001). CONCLUSIONS The Indonesian adaptation of the POSAS 3.0 is a valid and reliable tool for comprehensive keloid scar assessment. Future research should explore the responsiveness to therapeutic interventions.

BACKGROUND

Hand grip strength (HGS) is a tool to measure muscle strength, which is an important component in sarcopenia and frailty. Grip strength (GS) in midlife can predict physical disability in senior years and help evaluate a patient's overall health.

OBJECTIVES

The general purpose of this study is to validate the HGS using an aneroid sphygmomanometer and Jamar dynamometer as a diagnostic tool for sarcpenia. The specific aims of this study are (a) to determine the concurrent criterion validity, (b) to determine the reliability, and (c) to measure the inter-rater agreement of the aneroid sphygmomanometer against the Jamar dynamometer in measuring HGS.

METHODS

This prospective validation study measures HGS using an aneroid sphygmomanometer and Jamar dynamometer obtained from seventy participants 50 years old and above. Statistical methods used in data analysis include Spearman Rho, univariate linear regression analyses, intra-class correlation, inter-rater reliability, intra-rater reliability, Bland-Altman plots, and Lin’s concordance.

RESULTS

There was a significant correlation of HGS with the Jamar dynamometer and aneroid sphygmomanometer regardless of the rater [Spearman Rho (rs=0.762 to 0.778, p=0.001)]. Jamar GS is comparable to GS using a sphygmomanometer with the formula of [Jamar = 0.54 x sphygmomanometer (mmHg) - 45.12].

CONCLUSION

Aneroid sphygmomanometer can be used as an option to measure GS and has a valid value to predict the Jamar GS value. Hence, it can be an alternate tool for diagnosing sarcopenia.

Objective: Musculoskeletal ultrasound has gained recognition in early identification of crystal deposits in the joints and soft tissues. This study aims to validate the sonographic features of 1st metatarsophalangeal joints (MTPJs) in gout and asymptomatic hyperuricemia (AH). Methods Patients with gout (n=20) and AH (n=16) underwent a gray-scale ultrasound assessment of both 1st MTPJs on 3 positions (dorsal, medial, plantar) in longitudinal view. The static images were read by 2 blinded trained sonologists for the presence of double contour sign (DCS), erosions, and tophi.

Background: In 2009, the World Health Organization revised the Dengue Fever guidelines to more accurately identify patients at risk of developing severe dengue. Despite these guidelines, early diagnosis of severe dengue remains challenging for clinicians. Several scoring systems have been developed to identify patients at highest risk for severe dengue however; these studies have a study population limited to children and did not include adult patients. Objective: The purpose of this study is to validate the Simple Clinical Risk Score in predicting who will develop severe Dengue among adult patients with Dengue fever. Methods: This is a prospective cohort, single-center, observational study conducted at Silliman University Medical Center from August 2019 to August 2020. A total of 481 laboratory confirmed dengue patients were included and categorized into two models based on the day of illness. Each model used a clinical risk score of 1 point as a cut-off for predicting severe Dengue. Validation was done using the risk-odds ratio and substantiated by the odds ratio, signifying that there is more likely greater association between dengue patients to develop severe dengue. Results: In model 1, a total of 339 patients were analyzed with 6 patients who achieved a score of 1 developed severe Dengue. In model 2, a total of 142 patients were analyzed and 3 patients who achieved a score of 1 developed severe dengue. Conclusion The simple clinical risk score can assist clinicians in deciding and stratifying dengue patients who need hospitalization not only in resource-limited areas but also during this height of the pandemic. While the findings had a lesser number of participants, it still remained context-specific and is able to demonstrate a predictive ability for severe disease, thereby optimizing informed decisions for hospital admissions in settings with limited laboratory resources.

Objective: This study aims to determine the convergent and discriminant validity and internal consistent reliability of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Tagalog among adult Filipinos with differentiated thyroid cancer (DTC). Methodology: 104 adult Filipinos with DTC at various disease stages self-administered the EORTC QLQ-C30 version 3 Tagalog and Short Form-36 (SF-36) version 2 Tagalog. Concurrent validity between conceptually-related scales from both tools was determined. Convergent and discriminant validity of multi-item scales of the EORTC QLQ-C30 Tagalog were assessed by Spearman’s correlation. Cronbach's α was computed. Results: The EORTC QLQ-C30 Tagalog showed moderate correlation with similar scales in the SF-36 Tagalog particulary for physical, role and social functioning, pain, and global health (r=0.42-0.48, p<0.001). It showed satisfactory item-domain convergent and discriminant validity for all scales except pain, fatigue, physical and cognitive functioning. Internal consistent reliability was good with cronbachs α ranging from 0.77 to 0.88 for global health, emotional and role functioning and symptom scale of nausea/vomiting. Conclusion The EORTC QLQ-C30 Tagalog had acceptable convergent and discriminant validity and internal consistent reliability for the scales of global health, role, social and emotional functioning and nausea/vomiting when applied among adult Filipinos with DTC.
