Indian kids more affected by their fathers' behaviour

Indian children, whose fathers display negative parenting traits such as detachment, intrusiveness,lax enforcement of discipline and controlling behavior, are likely to have lower self esteem,suggest a new research. This is because  children's self worth is linked to the behavior of dominant parent and in Indian culture, fathers generally play the central role-both within and outside the household.

"Mothers and fathers play different roles in different cultures--these findings highlight the importance of these distinct gender-based power structures on a child's self-worth," 

In contrast, in Western cultures, although still somewhat patriarchal, mothers have more central roles than fathers within the home and are often responsible for routine care and discipline.

Study found that English children,whose mothers displayed more negative parenting traits,reported lower self-esteem.But for Indian kids, the father behavior had more impact.

In India,traditionally the father is considered to be the Head of the family,in terms of power and their role as disciplinarian.These difference often remain even after families migrate to other countries.

"Parenting literature is still dominated by mothering, reflecting Western norms.
