Intergenerational transmission of sexual victimization vulnerability as mediated via parenting

Objectives

Previous research suggests that women's early sexual victimization experiences may influence their parenting behaviors and increase the vulnerability of their children to being sexually victimized. The current study considered whether mother's sexual victimization experiences, in childhood and after age 14, were associated with the sexual victimization experiences reported by their adolescent daughters, and if so, whether these effects were mediated via parenting behaviors.

Methods

The proposed model was examined using a community sample of 913 mothers and their college-bound daughters, recruited by telephone at the time of the daughter's high school graduation. Daughters reported on their experiences of adolescent sexual victimization and perceptions of mothers’ parenting in four domains: connectedness, communication effectiveness, monitoring, and approval of sex. Mothers provided self-reports of their lifetime experiences of sexual victimization.

Results

Consistent with hypotheses, mothers’ victimization was positively associated with their daughters’ victimization. The effect of mothers’ childhood sexual abuse was direct, whereas the effect of mothers’ victimization after age 14 was mediated via daughters’ perceptions of mothers’ monitoring and greater approval of adolescent sexual activity. Comparison of the prevalence of specific victimization experiences indicated that mothers were more likely to report forcible rape over their lifetimes; however, daughters were more likely to report unwanted contact and incapacitated rape.

Conclusions

Findings suggest that even in a highly functional community sample, mothers’ sexual victimization experiences are significantly associated with aspects of their parenting behavior and with their daughters’ own experiences of adolescent sexual victimization.     

Comparisons among Small Sample Equating Methods in a Common-Item Design

Score equating based on small samples of examinees is often inaccurate for the examinee populations. We conducted a series of resampling studies to investigate the accuracy of five methods of equating in a common-item design. The methods were chained equipercentile equating of smoothed distributions, chained linear equating, chained mean equating, the symmetric circle-arc method, and the simplified circle-arc method. Four operational test forms, each containing at least 110 items, were used for the equating, with new-form samples of 100, 50, 25, and 10 examinees and reference-form samples three times as large. Accuracy was described in terms of the root-mean-squared difference (over 1,000 replications) of the sample equatings from the criterion equating. Overall, chained mean equating produced the most accurate results for low scores, but the two circle-arc methods produced the most accurate results, particularly in the upper half of the score distribution. The difference in equating accuracy between the two circle-arc methods was negligible.
