A total of two hundred sixty three (263) secondary students of Davao City National High School from different grade levels and programs were chosen as respondents to answer the questionnaire on gangsterism. The total number of respondents satisfied the requirement of 10 is to 1 subject-item ratio of Nunnally (1978).

Measures of Sampling Adequacy and Sphericity
KMO and Bartlett's Test
Kaiser-Meyer-Olkin Measure of Sampling Adequacy. .756
Bartlett's Test of Sphericity Approx. Chi-Square 1191.498 df 190 Sig. .000

Based from the result, A KMO of .756 which is near 1 signifies a pattern for correlations that are relatively compact which provide reliable factors. In general, a KMO coefficient must be greater than 0.50. Literatures indicate that KMO values between 0.5 to 0.7 were mediocre; values between 0.7 to 0.8 were considered good; and values between 0.8 to 0.9 were great; while values above 0.93 were deemed superb, with the latter suggestive of strong confidence that factor analysis fit for the data (Tamayo, 2012). Moreover, Bartletts Test of Sphericity of 1191.498 is significant with a p-value of .000, which confirms that statements presented have patterned relationships. This means that the respondents understand the question the same with others.
