Development and psychometric evaluation of a quality of life questionnaire for infertile women: a mixed method study

Investigating different dimensions of infertile women's quality of life: a descriptive cross-sectional study

BACKGROUND

Infertility is a major challenge in the life of women which affects their quality of life. Infertile women's quality of life is a relatively new field of research that has recently been considered by health researchers. However, there has been no standard tool for measuring different aspects of infertile women's quality of life with female factors, and general and specific tools of infertile couples have been used to assess their quality of life. This study, thus, aimed to analyze different aspects of the quality of life of infertile women.

METHODS

This descriptive cross-sectional study was conducted on 320 infertile women referred to a teaching hospital affiliated with Mazandaran University of Medical Sciences and private infertility treatment centers in Sari, Iran. Demographic and fertility characteristics and the quality of life questionnaire for infertile women questionnaire (a 25-item tool was designed which measured 7 factors of psychological effects, sexual life with infertility family and social effects, infertility-related concerns, physical effects, adaptive approaches and factors preventing infertility adaptation), were recruited for data gathering. Data were analyzed using SPSS version 22. Descriptive statistics (percentage, mean, standard deviation), correlation coefficient, independent sample t-test, and multiple linear regression were used. P-values less than 0.05 were considered statistically significant.

RESULTS

The total mean score of infertile women's quality of life was 65.68 ± 8.91%. Findings were indicative of infertile women's quality of life in the dimensions of adaptive approach (70.48 ± 15.02%), psychological (67.88 ± 12.06%), family and social (64.63 ± 10.76%), physical, 63.42 ± 11.36%), inhibitory factors/ factors preventing adaptation (60.98 ± 8.24%), related concerns (51.52 ± 10.21%) and sexual life (40.12 ± 14.28%). According to the final multiple linear regression model, women's education (B = 2.57, p < 0.001), spouse's education (B = 1.56, p = 0.046), economic status (B = 1.64, p < 0.001), age of women (B = -0.62, p < 0.001), age of spouse (B = -0.65, p < 0.001), duration of infertility (B = -0.36, p = 0.024) and duration of marriage (B = -0.39, p = 0.022) were the final predictors of the quality of life score in infertile women of the study.

CONCLUSION

Given that infertility causes extensive changes in individuals, families, and social dimensions of infertile women, it can affect their quality of life. We can take steps to improve the health of infertile women by promoting various dimensions of their quality of life.

Psychometric properties of modified MOS social support survey 5-item (MSSS-5-item) among Iranian older adults

BACKGROUND

Social support is a key factor in public health. Since the precise evaluation of it is critical, the current study has been developed to evaluate the psychometric properties of the MOS-SSS questionnaire's abbreviated form (MSSS-5-item) among the Iranian older adults.

METHODS

This cross-sectional and methodological study was conducted on 420 community older adults (age ≥ 60) through random multi-stage sampling. The questionnaire was first translated into Persian through the Forward & Backward method based on WHO guidelines. Next, the validity of scales was investigated by calculating face validity, content validity, Known-group validity, explanatory factor analysis, and confirmatory factor analysis indices. The reliability of the questionnaire was calculated by internal consistency, test-retest, and absolute reliability. Moreover, the scalability of the questionnaire was checked through the Mokken scale analysis. The software packages SPSS version 22, AMOS version 22, and R (Mokken package) were employed to analyze the data.

RESULTS

the face validity was conducted using interviews with older adults and gathering the specialists' opinions. Then, the items were grammatically and lexically corrected accordingly. The CVI index of the overall scale was 0.94, and for every single item above 0.89. The results of the independent t-test showed that the current questionnaire well distinguished between the older adults who do and do not feel lonely (p < 0.001). Two components were recognized according to the explanatory factor analysis. They together explained 67.78% of the total variance of the questionnaire. The CFA showed that the two-factor model had acceptable fit indices. The questionnaire had desirable internal consistency (α = 0.78), stability (ICC = 0.98), and absolute reliability (SEM = 0.56, MDC = 1.57). Furthermore, the Mokken scale proved that MSSS-5-item was a strong scale (H = 0.51, se = 0.03).

CONCLUSION

The present study results showed that the MSSS-5-item questionnaire had suitable validity and reliability to be used among Iranian older adults.
