"Children aged 13-14 from single-parent families (mother-headed and father-headed households) and intact families are compared.... The main hypothesis states that slight differences may be expected on the happiness scale.... Similarities and dissimilarities of children's psycho-social image in both settings (mother-headed and father-headed households) as well as differences between intact-family children and single-parent children are discussed [in light of] recent findings about gender socialization, self-identity and single-parent family dynamics." The geographical scope is worldwide. (SUMMARY IN ENG)
