Büyüsel düşünce ölçeğinin psikometrik özelliklerinin liseye devam eden ergenlerde incelenmesi

Abstract

Objective: The validity and reliability studies of the Magical Ideation Scale (MIS) have already been conducted among university students. The purpose of this study was to define the psychometric properties of the MIS among adolescents attending high school. Method: Four hundred twenty two high school students attending an Anatolian High School and classical high schools within Kocaeli city center during the education year 2011-2012 participated in this research. Among the participants 222 (52.6%) were female and 200 (47.4%) were male. The average age of the students was 15.68±0.67. The participants were administered MIS and Irrational Belief Scale Adolescent Form (IBS-A). For the confirmatory factor analysis and reliability analysis, Cronbach alpha coefficient 27% sub-upper group method was used for the validation of the MIS. For the discriminant validity transaction of the scale, the correlation value was calculated with the IBS-A. Findings: After the confirmatory factor analysis transaction, Root Mean Square Error of Approximation (RMSEA) was found as 0.039; Non-normed Fit Index (NNFI) was calculated as 0.90; Comparative Fit Index (CFI) was calculated as 0.91; Incremental Fit Index (IFI) was found as 0.91; and Goodness of Fit Index (GFI) was found as 0.90. Besides, the internal consistency coefficient was found as ?=0.80 for female students and ?=0.76 for male students. In the discriminant validity study, the level of relation between the irrational beliefs and magical ideation was calculated as r=0.11. Conclusion: The validity and reliability analysis findings obtained from the study revealed that the MIS was a valid and reliable scale in measuring the magical ideation. Based on those findings, it may be stated that this scale would be sufficient in the studies to be conducted on the adolescents.
