RESUMO
Background: Depression has a high prevalence among European countries. Several instruments have been designed to assess its symptoms in different populations. The Hopkins Symptom Checklist 25 (HSCL-25) scale has been identified as valid, reproducible, effective, and easy to use. There are short versions of this scale that could be useful in Primary Care (PC) settings, but their psychometric properties are unknown. Aim: To assess in PC patients the psychometric properties and diagnostic accuracy of the Spanish version of the HSCL-10 and the HSCL-5 consisting of 10 and 5 items, respectively. Methods: A multicenter, cross-sectional study was carried out at six PC centers in Spain. The HSCL-25 was administered to outpatients aged 45-75 who also participated in the structured Composite International Diagnostic Interview (CIDI). HSCL-10 and HSCL-5 were assessed and compared to HSCL-25 regarding total score correlation, internal consistency, and criterion validity against the gold-standard CIDI. This is a methodological study from a secondary data analysis and the primary data has been previously published. Results: Out of 790 patients, 767 completed the HSCL-25 and 736 the CIDI interview (96.0%). Cronbach's Alpha was 0.84 for HSCL-10 and 0.77 for HSCL-5. The known-group method and confirmatory factor analysis were acceptable for the establishment of construct validity. Sensitivity was 79.7% (CI95%, 67.7-88.0%) for HSCL-10, and 78.0% (CI95%, 65.9-86.6%) for HSCL-5, whereas specificity was 83% (CI95%, 80.0-85.7%) for HSCL-10, and 72.8% (CI95%, 69.3-76.0%) for HSCL-5. Area under the curve against CIDI was 0.88 (CI95%, 0.84-0.92%) for HSCL-10, and 0.85 (CI95%, 0.81-0.89%) for HSCL-5. Optimum cutoff point calculated with Youden Index was 1.90 for the HSCL-10 and 1.80 for the HSCL-5. Conclusion: HSCL-10 and HSCL-5 are reliable and valid tools to detect depression symptoms and can be used in PC settings.
RESUMO
Depression constitutes a major public health problem due to its high prevalence and difficulty in diagnosis. The Hopkins Symptom Checklist-25 (HSCL-25) scale has been identified as valid, reproducible, effective, and easy to use in primary care (PC). The purpose of the study was to assess the psychometric properties of the HSCL-25 and validate its Spanish version. A multicenter cross-sectional study was carried out at six PC centers in Spain. Validity and reliability were assessed against the structured Composite International Diagnostic Interview (CIDI). Out of the 790 patients, 769 completed the HSCL-25; 738 answered all the items. Global Cronbach's alpha was 0.92 (0.88 as calculated for the depression dimension and 0.83 for the anxiety one). Confirmatory factor analysis (CFA) showed one global factor and two correlated factors with a correlation of 0.84. Area under the curve (AUC) was 0.89 (CI 95%, 0.86-0.93%). For a 1.75 cutoff point, sensibility was 88.1% (CI 95%, 77.1-95.1%) and specificity was 76.7% (CI 95%, 73.3-79.8%). The Spanish version of the HSCL-25 has a high response percentage, validity, and reliability and is well-accepted by PC patients.
