Development of a context-specific trauma scale among a Palestinian adult population living amidst military violence.

The current study aimed to develop a context-specific trauma scale in the Palestinian context. The sample of our study consisted of 490 Palestinian adults - 230 males and 260 females. Our scale ended up with 32 items to measure traumatic symptoms in the Palestinian context. Results of exploratory factor analysis and confirmatory factor analysis revealed a stable construct of a five-factor structure of the Palestinian specific-context trauma: (1) re-experiencing trauma, (2) avoidance and numbing, (3) hyperarousal, (4) somatic symptoms and (5) psychological symptoms. Reliability of the scale was further established by assessing the test-retest and internal consistency of all subscales. Convergent validity for the context-specific trauma scale was conducted by testing the association between the scale and two existing measures - the WHOQOL-BREF and the Impact of the Event Scale (IES-R). We recommend using our scale in empirical studies incorporating spoken or written disclosure about traumatic experiences. The scale should also be considered when working with clinical and non-clinical groups who have experienced politics-related trauma.
