“…An extensive body of work makes it clear that the more family structure transitions children face, the lower their level of well‐being on average (for recent reviews, see Cavanagh & Fomby, ; Hadfield, Amos, Ungar, Gosselin, & Ganong, ). This pattern holds across multiple domains of well‐being, including problem behavior (e.g., Cooper, Osborne, Beck, & McLanahan, ; Fomby & Mollborn, ; Fomby & Sennott, ; Mitchell et al, ), health (Bzostek & Beck, ; Smith, Crosnoe, & Cavanagh, ), and emotional well‐being (e.g., Bzostek & Berger, ; Lee & McLanahan, ), as well as socioeconomic attainment and relationship stability in adulthood (e.g., Amato & Patterson, ; Bloome, ; Fomby, ; Fomby & Bosick, ). A range of explanations have been offered for the association between family instability and reduced offspring well‐being—generally focusing on changes in economic resources, parenting, and emotional stress—but empirical support for such mechanisms remains surprisingly modest (Cavanagh & Fomby, ).…”
