About this dataset

The Study Characteristics dataset includes basic information about study design. Data is at the study level. In addition to study class, the dataset includes clinical setting, whether the study looked at PTSD symptom clusters, whether there were any subgroup analyses, type of diagnostic measure used (e.g., diagnostic interview, self-report), whether between-group comparison data is available for other outcomes (in addition to PTSD) and provider credentials. Use this dataset to better understand the variety of RCT designs employed, compare studies by study class or to identify gaps in the literature for potential new RCTs. Values reported as "NA" or not reported "NR" by the study are null values (empty cells).
