teenagers. The interaction effect, of ethnicity x age was significant (F2, 1488)= 3.9 P < .04, age x gender
interaction was significant (F1,1488) = 5.03 p<.04.Ethnicity x age x gender interaction also significant (F2,
1488)=4.03p<.04 Scheffe test of comparison showed that Ogoni teenagers scored highest in the social adjustment
