This study examined the psychometric properties of Retired Spousal Intrusion Scale (SRSI). The calibration study was conducted with a sample of women (n = 687) whose husbands were retired, resulting in a one factor scale consisting of six items. Validation study, discriminant validity and test-retest were conducted in a second sample of women (n = 756) whose husbands were retired. The results of the confirmatory factor analysis revealed that the unidimensional factor model had adequate fit with values chi(2)/df = 4.61, GFI = .98, AGFI = .96, CFI = .96, RMSEA = .06, SRMR = .05. In addition, the correlation of the SRSI with conceptually unrelated measures (dyadic adjustment scale and quality of life) supported the discriminant validity of the SRSI. Finally, analyses showed that SRSI is a valid and reliable measure to assess retired husbands' intrusion on their wives.
