Influences of parental drug use, personality, and child rearing on the toddler's anger and negativity.

How parental personality and drug use and the parent-child relationship are related to a toddler's anger and negativity was investigated. The sample consisted of 62 female and 53 male 2-year-old children and their parents. The results supported a mediational model. The father's drug use and parental personality attributes were linked to the child's anger and negativity indirectly, through the parent-child relationship. The findings indicated that maternal personality and child-rearing practices had a greater effect on the child than the paternal characteristics or the father-child relationship did. The results also suggested that the effect of one parent on the child was altered by the relationship the child had with the other parent. Implications for prevention and treatment are discussed.
