Objective: The aim of this study was to investigate the reliability and validity of the "Shortened Level of Expressed Emotion Scale", which measures expressed emotion in adolescents, to assess its applicability in the Turkish population. Material and Methods: The study was carried out with 1010 students registered in public schools from three different socioeconomic statuses. Of the study population, 57.4% were girls, 42.5% were boys and the mean age was 14.08 ±1.49 years. Scale reliability was examined with Cronbach alpha reliability coefficient and test-retest method. The scale was examined in terms of criterion and construct validity. To examine criterion validity, "Children Depression Inventory" was also given in addition to the scale to be investigated. To investigate the construct validity, confirmatory factor analysis was run and statistical comparisons were done to examine the ability of the scale to determine different constructs. Results: When the scale reliability was examined Cronbach alpha coefficient was 0.90 and test-retest reliability was 0.81 (p<0.001). Confirmatory factor analysis revealed that three factor models were appropriate for the "Shortened Level of Expressed Emotion Scale". Lack of emotional support sub-scale and total scale in terms of socioeconomic status, and lack of emotional support, irritability, and intrusiveness subscales in terms of gender were successful to determine the different constructs (p<0.05). Criterion validity analysis revealed a significant correlation between the scale tested and the "Children Depression Inventory" (r=0.50; p<0.001). Conclusion: Reliability and validity analyses revealed that the "Shortened Level of Expressed Emotion Scale", which was proposed by Nelis et al. was applicable in Turkish adolescents. © 2013 by Türkiye Klinikleri.
