This study investigates the differences between Romanian mothers and daughters (61 dyads) regarding sexual dysfunctional beliefs (SDF) and their associations with religion, religiosity and residence (rural, urban). Each individual (mother, daughter) filled in the Sexual Dysfunctional Beliefs Questionnaire (Nobre, Gouveia & Gomes, 2003), as well as demographic questions. Mothers significantly endorsed almost all SDF more than did daughters. The SDF endorsement was associated with religiosity and rural residence, but not with religion orientation. In addition, mothers and daughters differed in the correlations between the SDBQ subscales and religiosity. Together, these results provide preliminary support for the development of more efficient sexual education tools, i.e. sexuality programs for adult population. Further research is needed to better understand the role mother-daughter relationship and the attachment style have on SDB and the way the latter impact marital satisfaction. Our results hold some practical relevance in the area of sexual education in Romania, as well as in the area of family interventions.
