Development of a Quality of Sexual Life Questionnaire for Breast Cancer Survivors in Mainland China

Predictors of social intermediate factors associated with sexual quality of life of women: systematic review and meta-analysis

BACKGROUND

Sexual problems and diminished sexual quality of life can adversely affect the physical, psychological, and emotional health of women. The present study was done to determine the social intermediate factors of health associated with sexual quality of life in women of reproductive age.

DESIGN

Systematic review and Meta-analysis.

DATA SOURCES

Embase, Web of Science, PubMed/Medline (NLM), ProQuest, and CENTRAL.

ELIGIBILITY CRITERIA

Observational studies (cross-sectional, case-control, cohort) from 2010 to 2022 with no language constraints were included. The sexual quality of life, as the main variable of the study, has been evaluated using Symonds women's sexual quality of life scale (SQOL-F). The health social determinants intermediate factors based on WHO model were considered as exposure variables.

DATA EXTRACTION AND SYNTHESIS

The data of included studies were extracted by two independent persons through a researcher-made checklist according to the study aims. Quality assessment of studies was done using Newcastle-Ottawa instrument. R software (Version R-4.2.1) were used for meta-analysis. Publication bias was evaluated by Egger & Begg tests. Sensitivity analysis was done through one-out remove approach.

RESULTS

Eventually, 15 studies were eligible to be included in this systematic review and meta-analysis. Variables of depression, quality of marital relation, body image, self-esteem, physical activity, and sexual function were among the health social intermediate factors associated with sexual quality of life. Publication bias had no effect on the obtained results; no study affecting the results was found through sensitivity analysis.

CONCLUSION

Considering the relationship between modifiable factors and sexual quality of life, it seems that identification of these factors can be an important step towards designing interventional studies to help women experience enhanced sexual quality of life.

Quality of sexual life and associated factors: a cross-sectional survey of Chinese breast cancer patients

PURPOSE

This study aimed to explore Chinese breast cancer patients' quality of sexual life (QSL) and factors associated with QSL.

METHODS

The questionnaires in this cross-sectional study include the general information questionnaire, cognition and assessment of sexual health questionnaire, Self-acceptance Questionnaire (SAQ), Medical Coping Modes Questionnaire (MCMQ), and Quality of Sexual Life Questionnaire (QSLQ); 201 breast cancer patients were required to complete the questionnaires assessing characteristic information, cognition and assessment of sexual health, QSL, self-acceptance, and coping style. Finally, hierarchical regression was used to analyze the factors associated with QSL in Chinese breast cancer patients.

RESULTS

The mean age (at the time of the survey) of the breast cancer patients was 48.31±9.15. The mean score of the QSLQ (range 28-140) was 75.14±16.57. Hierarchical regression analysis showed that the associated factors of breast cancer patients' QSL included age (at the time of the survey), education level, type of surgery, cognition and assessment of sexual health, self-acceptance, and avoidance and acceptance-resignation coping styles, that independent variables explained 60.4% of the variance.

CONCLUSION

The QSL among Chinese breast cancer patients needs to be improved. Our findings indicated that breast cancer patients with older age, lower education level, or modified radical mastectomy have poor QSL. Breast cancer patients learn correct information about sexual health, enhance self-acceptance, and reduce acceptance-resignation, and avoidance coping could be intervention strategies to improve their QSL.

Psychological interventions for sexual function and satisfaction of women with breast cancer: A systematic review and meta-analysis

AIMS AND OBJECTIVES

To systematically evaluate the effectiveness of psychological interventions for women with breast cancer on sexual function, sexual satisfaction, sexual relationships, sexual distress and sexual quality of life.

BACKGROUND

Sexual dysfunction is common in women with breast cancer and seriously affects their quality of life and marital harmony. Several studies have explored the effects of psychological interventions related to sexual function of women with breast cancer, but results were inconclusive.

DESIGN

A systematic review and meta-analysis based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

METHOD

A search of PubMed, EMBASE, PsycINFO, Web of Science, the Cochrane Library, Scopus, CINAHL, ProQuest Dissertations and Theses Global, ClinicalTrials.gov. and Open Grey was conducted from inception to 9 May 2021. Two reviewers independently screened studies, extracted data and conducted a quality appraisal of included studies using the Joanna Briggs Institute critical appraisal checklists.

RESULTS

Fifteen studies involving 1307 participants were included. The current study showed that psychological interventions made statistically significant improvements in sexual function (SMD = 0.82; 95% CI = [0.43, 1.20]; p < .001), sexual satisfaction (SMD = 0.95; 95% CI = [0.19, 1.72]; p = .01), sexual relationships (SMD = 0.37; 95% CI = [0.15, 0.60]; p = .001) and sexual distress (MD = -5.05; 95% CI = [-7.88, -2.22]; p = .0005) of women with breast cancer. A subgroup analysis regarding the types of psychological interventions indicated that cognitive behavioural therapy and psychoeducational therapy were beneficial to sexual function and satisfaction, and psychosexual counselling could also improve sexual function.

CONCLUSION

Psychological interventions, especially psychoeducational therapy and cognitive behavioural therapy, are effective for improving the sexual health of women with breast cancer.

RELEVANCE TO CLINICAL PRACTICE

This current study provides evidence for the application of psychosexual interventions in women with breast cancer.

The Female Sexual Function Index (FSFI)-A Systematic Review of Measurement Properties

INTRODUCTION

The Female Sexual Function Index (FSFI) is a patient-reported outcome measure measuring female sexual dysfunction. The FSFI-19 was developed with 6 theoretical subscales in 2000. In 2010, a shortened version became available (FSFI-6).

AIM

To investigate the measurement properties of the FSFI-19 and FSFI-6.

METHODS

A systematic search was performed of Embase, Medline, and Web of Science for studies that investigated measurement properties of the FSFI-19 or FSFI-6 up to April 2018. Data were extracted and analyzed according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. Evidence was categorized into sufficient, insufficient, inconsistent, or indeterminate, and quality of evidence as very high, high, moderate, or low.

MAIN OUTCOME MEASURES

The Main Outcome Measure is the evidence of a measurement property, and the quality of evidence based on the COSMIN guidelines.

RESULTS

83 studies were included. Concerning the FSFI-19, the evidence for internal consistency was sufficient and of moderate quality. The evidence for reliability was sufficient but of low quality. The evidence for criterion validity was sufficient and of high quality. The evidence for structural validity was inconsistent of low quality. The evidence for construct validity was inconsistent of moderate quality. Concerning the FSFI-6, the evidence for criterion validity was sufficient of moderate quality. The evidence for internal consistency was rated as indeterminate. The evidence for reliability was inconsistent of low quality. The evidence for construct validity was inconsistent of very low quality. No information was available on structural validity of the FSFI-6, and measurement error, responsiveness, and cross-cultural validity of both FSFI-6 and FSFI-19.

CLINICAL IMPLICATIONS

Conflicting and lack of evidence for some of the measurement properties of the FSFI-19 and FSFI-6 indicates the importance of further research on the validity of these patient-reported outcome measures. We advise researchers who use the FSFI-19 to perform confirmatory factor analyses and report the factor structure found in their sample. Regardless of these concerns, the FSFI-19 and FSFI-6 have strong criterion validity. Pragmatically, they are good screening tools for the current definition of female sexual dysfunction.

STRENGTH & LIMITATION

A strong point of the review is the use of predefined guidelines. A limitation is the use of a precise rather than a sensitive search filter.

CONCLUSIONS

The FSFI requires more research on structural validity (FSFI-19 and FSFI-6), reliability (FSFI-6), construct validity (FSFI-19), measurement error (FSFI-19 and FSFI-6), and responsiveness (FSFI-19 and FSFI-6). Further corroboration of measurement invariance (both across cultures and across subpopulations) in the factor structure of the FSFI-19 is necessary, as well as tests for the unidimensionality of the FSFI-6.
