Confirmatory factor analysis of the Sexual Adjustment and Body Image Scale in women with gynecologic cancer

Abstract

BACKGROUND: There is evidence that treatment of gynecologic cancer (GC) negatively affects body image and sexuality. The Sexual Adjustment and Body Image Scale (SABIS-G) was developed to assess disturbances after diagnosis of GC. The objective of this study was to confirm the factor structure using a confirmatory factor analysis (CFA). METHODS: Women with a history of GC completed the SABIS-G, a 9-item self-report measure. Ninety randomly selected participants were used for the exploratory factor analysis (EFA). CFA was performed on the remaining participants (n ¼ 204) to confirm the factor structure developed in the EFA against a one-factor model. Test-retest reliability between baseline and follow-up scores was assessed using the intraclass correlation coefficient. RESULTS: A total of 614 eligible patients were approached to participate: 398 (65%) consented to the study and 294 (74%) completed the SABIS-G. The median age was 53 years (range, 27-80 years) and the primary site of disease was: 120 (41%) uterine, 85 (29%) ovary, 82 (28%) cervix, and 7 (2%) other. A 2-factor structure was favored in the EFA, and the CFA fit indices indicated an excellent fit for the 2-factor measurement model (standardized root-mean-square residual ¼ 0.05, non-normed fit index ¼ 0.97, comparative fit index ¼ 0.98). Internal consistency reliability was high for the Body Image (0.88) and Sexual Adjustment (0.91) subscales, as was test-retest reliability (0.89). CONCLUSIONS: These results confirm the 2-factor structure of the SABIS-G and provide evidence that this is a valid and reliable instrument to measure changes in body image and sexuality in women after a diagnosis of GC.

Adaptation of the Sexual Adjustment and Body Image Scale in Turkish Breast Cancer Women

“…Ferguson et al also found that the scale had an RMESA of 0.08. This showed that the adapted version of the scale had a good fit (Ferguson et al, ).…”

“…Ferguson et al. () found in their study on women with gynecological cancers that Cronbach's alpha coefficient was 0.91 for sexual adjustment and 0.88 for body image.…”

“…The number of the items in the scale, administered to patients with gynecological cancers, was reduced to seven, and the factor loadings of the new scale ranged from 0.75 to 0.94 for sexual adjustment and from 0.79 to 0.89 for body image (Ferguson et al., ). To calculate the variance explained by a factor and to determine the number of factors, the Eigen value is used.…”

Prevalence of Physiologic Sexual Dysfunction Is High Following Treatment for Rectal Cancer

“…more recently, the sexual adjustment and Body image scale (saBis) for patients with breast cancer and the saBis-G for patients with gynecologic malignancies have been developed as tools to identify patients who are "significantly distressed" by problems with sexual function and/or sexual well-being. 18,19 these scales have been used to develop internet-based online support and sex therapy for patients in distress and have been shown to be feasible and effective in both female and male patients. 20,21 Ball et al 22 have performed a qualitative study of 13 male patients 6 years following treatment for rectal cancer and have found similar results.…”

Finite element modelling of Chinese male office workers’ necks using 3D body measurements

“…Considering the variation in the structure of necks among Chinese young males, neck classification was first conducted before the 3D model (Alexander, 1994;Brown, Cash, & Mikulka, 1990;Ferguson et al, 2012 andJiang, Zhang, Xia, &Hou, 2008). In this study, a factor analysis with varimax rotation was conducted on the 11 measurement parameters.…”
