Introduction: Sexualdysfunctions are a frequent condition that affects women’s qualityof life. Their estimated prevalence goes from 25% to 60%, dependingon the measuring instrument and the studied population. Their impacton the quality of life, and especially on female sexuality, is notusually considered as a measuring instrument, and there is noreliable instrument for evaluating it in Chile. “Sexual Quality ofLife Questionnaire - Female” (SQOL-F) is an instrument that hasbeen validated in England, the United States of America, and Iran,and evaluates the relation between sexual dysfunctions and quality oflife.
Objective: To analyze the structure and reliabilityof the tool for measuring sexual quality of life, “SQOL-F”, inwomen from the Province of Concepción, Chile.
Methods: Thequestionnaire was translated following the model proposed by theWorld Health Organization (WHO). 486 students from two universities(one public, the other private) in the city of Concepción, Chile,filled in a sociodemographic questionnaire and the SQOL-F. 344 ofthem met the requirements: being healthy, older than 18 years old,and having had sexual activity recently. The latter is defined as anysexual activity done in the three months previous to taking thequestionnaire. An exploratory factor analysis (EFA) was done,evaluating pertinence, number of factors, and factorial structure.Factor reliability was evaluated, too, with Cronbach’s α. Stata SE11 was used to process the data. This study was approved by the localEthics Committee.
Results: Average age was 21 years old(18-36). 91.8% was single, 5.81% had children, and 93.3% identifiedas heterosexual. A first exploratory factor analysis was done,showing that item 7 was not necessary. Then, the analysis wasrepeated with the remaining 17 items. Cattell, Kaiser-Guttman, andHorn criteria coincided in two factors, which, according to theconfiguration matrix, were classified as sex life satisfaction andsexual self-esteem. These factors showed an excellent reliability,according to the classification by George and Mallery (Cronbach’sα: 0.83 and 0.77, respectively), and had a very high itemdiscrimination ability.
Conclusions: The construct validityand reliability of the questionnaire show evidence to consider it asadequate for measuring sexual satisfaction in adult Chilean women.Nonetheless, further testing of its validity with a confirmatoryfactor analysis and other types of reliability, such as its temporalstability, would be preferable, as it is done for all psychometricstudies.
