Validity and reliability of the Persian version of the Suboptimal Health Status Questionnaire among university staff in Iran

Abstract

Background Suboptimal Health Status Questionnaire-25 (SHSQ-25) is an established tool for measuring a precision health state between health and illness. The present study aims to assess the validity and reliability of a Persian version of SHSQ-25 (P-SHSQ-25) in a university staff Iranian population. Methods A sample of 316 academic and supporting staff (163 males, age range from 23 to 64 years old) from Hamadan University of Medical Sciences, Hamadan, Iran was recruited in this population-based cross-sectional study with a questionnaire validation from Apri1 to October 2022. Forward-backward translation method was performed for the SHSQ-25 translation from English to Persian. Internal reliability, content, convergence, discriminative and construct validity of the P-SHSQ-25 were examined. The factorial structure of the P-SHSQ-25 across groups was examined using measurement invariant test. ResultsIn the translation process, the conceptual equivalence of the P-SHSQ-25 with the English version was confirmed. The item-content validity index and content validity ratio of all P-SHSQ-25 items were higher than the cut-off values of 0.70 and 0.62, respectively. Cronbach's α was higher than 0.70 for all P-SHSQ-25 domains. The confirmatory factor analysis (CFA) showed the fitness of five factors on the data set (comparative fit index = 0.88, and root mean square error of approximation = 0.07). The CFA model fit did not change substantially across sex, age, occupation, economic status, and body mass index (Δ comparative fit index (CFI)<0.01). ConclusionsThe P-SHSQ-25 can be used as a reliable and valid tool to measure health status for screening pre-chronic disease conditions in a primary care setting among Iranian population.

Assessing suboptimal health status in the Saudi population: Translation and validation of the SHSQ-25 questionnaire

“…This study's results demonstrate the consistency of the items in the five domains with the SHSQ-25 English version [10]. The present findings are consistent with earlier investigations that compared the factor structure of SHSQ-25 in Urban Chinese [10], Korea [16], Ghana [18], and, more recently, Iran [14]. This study suggests that the ASHSQ-25 is a valid and reliable instrument for discovering SHS among Arabic-speaking people.…”

“…Although SHS is not an illness condition, it mainly shows the period antedating the occurrence of clinical symptoms of diseases [1,2]. The SHSQ-25 instrument has earned worldwide recognition for the early detection of chronic diseases in many countries, such as China, Australia, Canada, Ghana, and Russia [10][11][12][13][14][15][16][17][18][19]. This instrument is a reliable five domains scale, validated in ethnic groups such as Asian [10,14], Caucasian [17], and African [18].…”

This instrument is a reliable five domains scale, validated in ethnic groups such as Asian [10,14], Caucasian [17], and African [18]. As an instituted instrument from the view of precision health care, the SHSQ-25 can be applied to discover a person experiencing illness without a diagnosable tool in the health care and community sectors.…”

“…These five domains include fatigue, cardiovascular system, digestive tract, immune system, and mental status. SHSQ-25 has gained increased popularity in the past few years and has been used by researchers to measure sub-health status in various studies [12][13][14][15]. However, at present, it has been assessed for its psychometric properties in limited regions of the world, translated into a few languages [5].…”
