Abstract
The aim of the present study was to test the psychometric properties of the Aggression Questionnaire Short Form for adolescents and adults in Turkish. The adaptation study was conducted with 778 adolescents aged between 15-18 and 1067 adults aged between 19 and 44. The construct validity of the questionnaire was tested via Parallel Analysis, Exploratory Factor Analysis and Confirmatory Factor Analysis. Furthermore, item-total correlations, test-retest score correlation, and internal consistency (Cronbach Alpha and McDonald’s Omega) were calculated as reliability analyses. The Measurement Invariance test and Differential Item Functioning in male and female, adolescent and adult samples were also conducted. The results yielded that the Turkish version of the Aggression Questionnaire Short Form is a reliable questionnaire with four-factors, and without sex and age differences, it can be used to measure aggression among Turkish adolescents and adults.
Highlights
Aggression is a multidimensional construct that develops within a complex interaction of biological, psychological, social, and cultural factors (Vitoratou, Ntzoufras, Smyrnis, & Stefanis, 2009) and has received great deal of attention in mental health area (Evren, Çınar, Güleç, Çelik, & Evren, 2011; Hinshaw; 1987; Johnson, Carve, & Joormann, 2013; Podubinski, Lee, Hollander, & Daffern, 2017)
Skewness and Kurtosis values were examined (n = 1067, data set for Parallel Analysis (PA), Exploratory Factor Analysis (EFA), and Confirmatory Factor analysis (CFA))
This study aims to make the adaptation of the Aggression Questionnaire Short Form in Turkish with adolescent and adult samples
Summary
Aggression is a multidimensional construct that develops within a complex interaction of biological, psychological, social, and cultural factors (Vitoratou, Ntzoufras, Smyrnis, & Stefanis, 2009) and has received great deal of attention in mental health area (Evren, Çınar, Güleç, Çelik, & Evren, 2011; Hinshaw; 1987; Johnson, Carve, & Joormann, 2013; Podubinski, Lee, Hollander, & Daffern, 2017). BPAQ is a 5-point Likert scale, consists of 29 items and has four factors These factors are physical aggression, verbal aggression, anger, and hostility. Different from the other instruments developed to measure aggression, BPAQ has validity for both adolescent (Reyna, Sanchez, Ivacevich, & Brussino, 2011) and adult samples (Vitoratou et al 2009). It is used with both clinical (Evren et al 2011) and nonclinical samples (Özdemir, Vazsonyi & Çok, 2017) rather than just with clinical or nonclinical ones (Palmstierna & Wistedt, 1987).
