Aim: The aim of this study is to develop a valid and reliable Multidimensional Trauma Scale compatible with DSM-5, which determines trauma and post-traumatic symptoms of individuals; also, to examine the psychometric properties of this scale.
Method: The sample group consists of 1054 individuals (843 females and 211 males) aged 18 years and over. The data were collected by using demographic information form, Childhood Trauma Scale, Post Traumatic Stress Disorder Checklist - Civil Version, Cognitive Emotion Regulation Scale, Coping Style Scale and Multidimensional Trauma Scale. Necessary analyzes regarding the validity and reliability of the scale were applied. Scale development steps were followed studiously and Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were applied, respectively in order to support the construct validity.
Results: As a result of the findings, the Childhood Traumas Scale, the first scale in the Multidimensional Trauma Scale consisting of 31 items and 6 sub-dimensions (emotional neglect/abuse, physical abuse, physical neglect, sexual abuse, secondary trauma and other traumas) and The Post-Traumatic Symptoms Scale, the second scale in the Multidimensional Trauma Scale consisting of 26 items and 6 sub-dimensions (avoidance, re-experience, hyperarousal, cognitive impairment, functional impairment, and dissociation symptoms) have been developed. While the total variance explained for the Childhood Traumas Scale was found as 62,58% and cronbach alpha reliability coefficient was identified as 0,87. The total variance explained for the Post-Traumatic Symptoms Scale was found as 67,19%, and cronbach alpha reliability coefficient was found as 0,94. The reliability values of the sub-dimensions vary between 0,50 and 0,91. The cut-off score was determined separately for each sub-dimension.
Conclusion: The Multidimensional Trauma Scale, consisting of 57 items and 12 sub-dimensions, was designed as a 5-point likert scale and has been presented to the literature.
