Anger in adolescence; Locus of control


Educational Psychology


The purpose of this study was to consider whether students who had been identified as having anger management difficulties have a significantly higher degree of External Locus of Control when compared to a random sample of their classmates. The participants included 45 students (18 males and 27 females) from a High School in the Northeast Region of the United States, between the ages of 14 to 19 years old.

The Nowicki-Strickland Internal External Locus of Control Scale for Children was used to assess the Locus of Control orientation in the subjects. The scores from the subject group were then compared to a random sample of their classmates, who formed the control group. The results of the instrument given to the two groups was analyzed using the Independent T Test for Two Independent Samples.

The study's t value did not fall within the rejection region, leading to the rejection of the null hypothesis and the acceptance of the alternate hypothesis that the subject group would have a significantly higher degree of external Locus of Control than the control group.
