Data Abstraction Half (seven) of the eligible studies were randomly selected and independently coded by two researchers. First, the parenting style reflected in each of these studies was reviewed and categorized into one of the two dimensions (warmth and control)and placed on the appropriate end of the dimension continuum (Parker et al., 1979). The general study characteristics, characteristics of the subjects, and methodological characteristics were identified on a standardized coding form. Each parenting behavior was labeled (Table 1). Data abstraction interrater agreement was 93%, and discrepancies between the labels of the researchers were discussed and resolved. After establishing the Validity and reliability of data abstraction, the remaining studies were coded by one researcher. The parenting behavior data were extracted using either the means (SD) or t value (p).
