Overparenting has been considered to contribute to offspring internalizing mental disorders from theoretical perspectives, which some empirical evidence has supported. However, existing findings are inconsistent. To facilitate the understanding of the association between overparenting and depression, anxiety, and internalizing symptoms, an examination of effect sizes is required. By employing the PRISMA method, a meta-analysis was conducted. Fifty-two articles were identified, with 38 studies examining depression, 30 studies examining anxiety, and 21 studies examining internalizing symptoms. The results show that overparenting is associated with offspring depression (mean age 19.94 years) (k = 133, r = .15, p < .001), anxiety (mean age 19.57 years) (k = 101, r = .14, p < .001), and internalizing symptoms (mean age 19.76 years) (k = 58, r = .19, p < .001). Moderator analyses show that the effect sizes are largely equal across SES groups, cultures, the age of offspring, child gender, and study design but may vary depending on the parental gender and report informants. Implications for interventions and future directions are discussed.

A high level of parental involvement is widely considered to be essential for optimal child and adolescent development and wellbeing, including academic success. However, recent consideration has been given to the idea that extremely high levels of parental involvement (often called ‘overparenting’ or ‘helicopter parenting’) might not be beneficial. This study used a newly created overparenting measure, the Locke Parenting Scale (LPS), to investigate the association of overparenting and children's homework. Eight hundred and sixty-six parents completed online questionnaires about their parenting beliefs and intentions, and their attitudes associated with their child's homework. Parents with higher LPS scores tended to take more personal responsibility for the completion of their child's homework than did other parents, and ascribed greater responsibility for homework completion to their child's teacher. However, increased perceived responsibility by parents and teachers was not accompanied by a commensurate reduction in what they perceived was the child's responsibility. Future research should examine whether extreme parental attitudes and reported behaviours translate to validated changes in actual homework support.

Is there a point where parental effort can be too much? While the link between parenting effort and the wellbeing of children has been firmly established, contemporary discussion has proposed that extreme levels of parental protection of and responsiveness to children could be counterproductive. Research has not yet addressed this phenomenon to ascertain if overparenting is a genuinely different type of parenting approach. The purpose of the present study was to gain insight into the parenting actions considered by parenting professionals (psychologists and school guidance counsellors) to be overparenting. One hundred and twenty-eight professionals responded to an online survey about their observations of overparenting, with eighty-six respondents providing lists of the types of actions they believed were behavioural examples of the term. The survey data revealed that certain types of actions were considered to be indicative of overparenting, and that particular beliefs and outcomes may be involved in this parenting approach. Implications for parenting advice and education programs, and further research are discussed.
