Human service organizations (HSO) have increasingly recognized the value of employing trauma-informed care (TIC) in a variety of practice settings. Evidence suggests that effectively adopting TIC has shown client improvements. Organizational barriers to TIC implementation, however, exist. To improve TIC practice, the attitudes related to trauma-informed care (ARTIC) scale was developed to measure staff attitudes and beliefs towards TIC. The ARTIC has been widely adopted by researchers without evaluating its psychometric performance in diverse practice settings. The purpose of this study was to independently validate the ARTIC scale drawn from a sample of staff (n = 373) who provide services to substance-using parents. Psychometric tests were conducted to evaluate how the ARTIC performs with our HSO population. Results from a confirmatory factor analysis showed poor fit (X2= 2761.62,df= 2.96; RMSEA = 0.07 [0.07, 0.08]; CFI = 0.72). An exploratory factor analysis was conducted to analyze how the data fit with our specific population, yielding 10 factors. Finally, a qualitative inter-item analysis of these factors was conducted, resulting in nine factors. Our findings suggest that measuring TIC attitudes and beliefs may vary according to field of practice and ethno-racially diverse workers. Further refinement of the ARTIC may be necessary for various services domains.
