Resumen:
Objective: The objective of this work was to design and validate a questionnaire on Male Sexual Function (MSF) in the Spanish language, following the criteria contemplated in the Diagnostic and Statistical Manual of Mental Disorders, DSM-5, for the diagnosis of sexual dysfunctions.
Material and methods: A cross-sectional and multicentre study was conducted on 163 men (18-70 years) who self-completed a test (MSF questionnaire). They then answered questions on the Structured History of Male Sexual Function (AMSF). Four weeks later they completed a re-test, which was the same, but including a supplementary question about the possible influence of recent events.
Results: Internal consistency: Cronbach's alpha test 0.840, AMSF 0.835, retest 0.855. Test-retest reliability: mean test scores 33.13 +/- 6.566, retest 33.11 +/- 6.791; Student t 0.122, not significant (P = .903); correlation total test-retest scores (intraclass correlation coefficient) 0.979, significant correlation (P <.01); total correlations test-AMSF scores (intraclass correlation coefficient) 0.966, significant correlation (P <.01). Concordance: between questions of the AMSF test (Kappa index) minimum 0.749, maximum 0.934; between test-retest questions: 0.724, 0.844. Content validity using expert consensus. Criteria validity: specificity > 90% for all items / domains, sensitivity > 80% except item 4 (76%). Content validity: using factor analysis, grouping of items into 4 components (explain 75% variance); high correlation between "sexual desire" and "confidence in erection''.
Conclusions: The MSF questionnaire is reliable, stable and valid, with high specificity and sensitivity. It evaluates the sexual response of the male, describing aspects of interest: anticipatory anxiety, initiative, confidence to communicate preferences, events that may influence. Can detect sexual dysfunction in the couple. (c) 2020 Sociedad Espanola de Medicos de Atencion Primaria (SEMERGEN). Published by Elsevier Espana, S.L.U. All rights reserved.
