The objectives of this survey research were to study child rearing pattern according to Basic Minimum Needs and Services for Children in children aged 6-24 months old and factors affecting child rearing pattern. The samples were 226 mothers whose child was 6-24 months old from 18 villages in Nongphok district, Roi-et province. The data was collected by interviewing mothers during the 1st to the 30th January 1994, with questionnaire constructed by researcher and parents relationship questionnaire taken from Pissawat Peerapakorns study . Statistics used for data analysis were percentage, mean, standard deviation, t-test, Analysis of Variance (ANOVA), Analysis of Covariance (ANCOVA) and Multiple Classification Analysis (MCA). The results showed that 82.7 percent of mothers practiced child rearing pattern at the middle level in part of physical care and 73 percent of mother had high level in part of developmental promotion The factors significantly associated with both part of child rearing pattern at p-value <0.05 were mothers education, fathers education, familys income, mothers work status, mothers knowledge about child care and child rearing and the accessibity for health services The parents relationship was significantly associated only with child rearing in part of physical care. The factors which were not significantly associated with both part of child rearing were mothers age, number of children and sex of the child. From Analysis of Covarince and Multiple Classification Analysis ,by using mothers education, parents relationship ,the accessibility for health services and mothers work status as independent variables the results showed that these four factors could describe the variation of child rearing in part of physical care significantly at p-value <0.05 (R(2) = 0.370 ). By using familys income, parents relationship, mothers knowledge and the accessibility for health services as independent variables these four factors could describe the variation of child rearing in part of physical care significantly at p-value <0.05 (R(2) = 0.371). By using mothers education, mothers work status, mothers knowledge and the accessibility for health services as independent variables these four factors could describe the variation of child rearing in part of developmental promotion significantly at p-value < 0.05 (R(2) = 0.158).
