IT WAS HYPOTHESIZED THAT FOUR PRIMARY FACTORS SIGNIFICANTLY INTERACT TO AFFECT THE PERSONALITY DEVELOPMENT OF CHILDREN. THESE FACTORS WERE (1) FAMILY BACKGROUND VARIABLES, (2) PARENTAL CHILD-REARING PRACTICE AND ATTITUDE VARIABLES, (3) CHILD PERSONALITY AND SELF-CONCEPT VARIABLES, AND (4) CHILD-PEER RELATIONSHIP VARIABLES. THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE PRESENCE OF THE INTERRELATIONSHIPS BETWEEN THE FOUR CATEGORIES OF VARIABLES. STUDENTS OF THE CASTLEBERRY SCHOOL DISTRICT NEAR FORT WORTH, TEXAS HAD PARTICIPATED FOR FOUR YEARS IN THE DISTRICT'S PEER RELATIONS PROGRAM. SOCIOMETRIC RATING SCORES WERE THUS AVAILABLE FOR A LARGE GROUP OF STUDENTS. THESE SCORES REPRESENTED A CHILD'S RATING ACCORDING TO HIS PEERS AND TEACHERS. BOYS AND GIRLS IN GRADES SIX, SEVEN, AND EIGHT WHO PLACED HIGH OR LOW ON THE SOCIOMETRIC RATING SCORE WERE THE SAMPLE POOL. THE PARENTS OF THESE CHILDREN WERE SOLICITED FOR PARTICIPATION IN THE STUDY AND WHEN 100 FAMILIES AGREED TO PARTICIPATE, THE SAMPLE WAS CLOSED. THE PARENTS AND CHILDREN WERE SUBSEQUENTLY ADMINISTERED A BATTERY OF INTERVIEWS, QUESTIONNAIRES, TESTS, AND RATING FORMS CONCERNING VARIABLE-CATEGORIES (1), (2), AND (3). THE RESULTS OF THESE DATA, PLUS THE SOCIOMETRIC RATING DATA USED IN SELECTING THE SAMPLE, WERE ANALYZED TO OBTAIN THE EXISTENCE OF THE INTERRELATIONSHIPS, IF ANY. SIGNIFICANT INTERRELATIONSHIPS BETWEEN THE FOUR GROUPS OF VARIABLES WERE FOUND TO EXIST. FAMILY BACKGROUND FACTORS WERE ASSOCIATED WITH VARIABLES AT EACH OF THE OTHER THREE LEVELS. FAMILY TENSION, A VARIABLE UNDER CATEGORY (2), HAD A DISRUPTING INFLUENCE ON CHILD-REARING PRACTICES, THE CHILD'S PERSONALITY DEVELOPMENT, AND SOCIAL ACCEPTANCE OF THE CHILD BY PEERS. ANOTHER CATEGORY (2) VARIABLE, PARENTAL LOVE OR REJECTION, ALSO INFLUENCED THE CHILD'S CHARACTER AND SOCIAL ACCEPTANCE. (WD)
