Construction and standardization of multidimensional anger scale in high school students

Different ways to express anger and its consequences is allocated to a special place in fundamental and applied psychological research. Constructing and validating a useful scale to measure anger is also another important point.

The aim of this research was to make and to find norms of multidimensional anger scale (anger arousal, hostile outlook, external and internal angers and anger-eliciting situations) among high school students.

The theoretical principles of the previous studies were studied first. Then, the researchers designed a questionnaire based on the framework resulted from studying the achieved resources. After studying the form and content of the raised questions in relation to each of the sub-tests and removing the inappropriate ones, 29 questions were performed for the final performance on a group composed of 400 students (212 males and 188 females) who were slected by the relative classification and random testing method.

The result of factor analysis by cycle method of Varimex of five factors equaling to 0/88, variance expression paralleling to theoretical principles of the structure were indicated. The sustainability of the questionnaire through Kranbuch alfa 0/87 and testing method-retest 0/81 and correlational results between the first and second performances in the five factors are 0/79 (Anger arousal), 0/81(Anger out), 0/77 (Hostile outlook) 0/86(Anger In), 0/83 (Anger-Eliciting Situation) respectively. The division method was used to get sure of the sustainability for the two halves 0/85 and 0/82 respectively. The total sustainability of the assumed test was 0/77. After analyzing the data, finding the norms, cut point and interference rate were calculated. The cut point for this test, in proportion with the average and standard deviation was 88/01. According to this cut point, the percent of interference rate 7/2 in the whole sample was 3/8 for the male and 11/2 for the female.

it can be suggested the multidimensional anger scale is a valid instrument to measure student's anger.
