Despite an increasing number of studies examining the impact of parental incarceration on children’s well-being, there are few comprehensive reviews that collect this information, and even fewer from a developmental perspective. This study aims to clarify the effects of parental incarceration on children’s well-being and development, as well as the moderating and mediating factors from a developmental perspective. A systematic review was conducted according to PRISMA guidelines, selecting 61 studies of children from early childhood to adolescence. The results show differences in the current evidence regarding the effects of parental incarceration on children depending on the developmental stage, with the most evidence in the 7–11-year-old stage. Being male appears as a risk moderator factor while the mental health of the caregiver and their relationship with the child appears as a mediating variable, especially from 7 to 18 years old. These results reveal the impact of parental incarceration based on children’s age, providing a basis for developing protective and intervention measures.

The main goal of this study was to investigate direct and indirect effects of attachment to parents on the formation of friendships, satisfaction with friends, and loneliness over the transition to college. Social anxiety and gender were tested as a possible mediator and moderator respectively. A total of 210 college freshmen at a large university in Spain participated in at a baseline assessment and a six-month follow-up assessment. Results demonstrated indirect effects of attachment to parents on ease forming friendships, satisfaction with friends, and loneliness through social anxiety, and a direct effect of attachment to loneliness. Gender did not play a moderating role. Taken together, these results suggest that programs to support the development of healthy social relationships across the college transition may be particularly beneficial for youth with challenges in familial relationships, and that screening for social anxiety may identify those students who would particularly benefit from support.
