Description
The Post-Traumatic Stress Disorder Questionnaire – PTSDQ Checklist-17 is a brief self-report instrument designed to assess symptoms associated with post-traumatic stress following exposure to a traumatic or highly stressful event.
The questionnaire consists of 17 items that reflect core manifestations of post-traumatic stress symptomatology, including intrusive recollections, avoidance of trauma-related stimuli, emotional numbing, and heightened physiological arousal.
Purpose
The primary purpose of the PTSDQ Checklist-17 is to provide a structured assessment of the severity and frequency of symptoms related to Post-Traumatic Stress Disorder (PTSD).
The instrument may be used to identify individuals with elevated levels of post-traumatic stress symptoms, monitor symptom changes over time, and evaluate possible improvement following psychological or therapeutic intervention.
Main Symptom Dimensions
The 17 items are generally organized around three major symptom domains:
Re-experiencing the Traumatic Event: includes intrusive memories, distressing dreams, intense psychological distress, or the feeling that the traumatic event is happening again.
Avoidance and Emotional Numbing: refers to attempts to avoid thoughts, feelings, conversations, people, or situations associated with the trauma, as well as reduced interest, emotional detachment, and restricted emotional responsiveness.
Hyperarousal: includes sleep difficulties, irritability, concentration problems, hypervigilance, and an exaggerated startle response.
Scoring
Respondents are asked to indicate the degree to which they have been bothered by each symptom during a specified period of time.
A total score is typically calculated by summing the responses to the individual items. Higher scores indicate more severe post-traumatic stress symptomatology.
Depending on the specific version of the instrument and the population being assessed, different cut-off scores may be used to indicate an increased likelihood of PTSD. Therefore, results should be interpreted according to the scoring guidelines of the specific version being administered.
Clinical and Research Applications
The PTSDQ Checklist-17 can be used in clinical, research, and community settings to assess post-traumatic reactions following accidents, natural disasters, violent incidents, serious threats, combat experiences, or other potentially traumatic events.
Its brief format makes it suitable for screening procedures, epidemiological research, and studies involving large samples.
Interpretation
The PTSDQ Checklist-17 should not be used as a stand-alone diagnostic instrument. An elevated score indicates the presence of clinically relevant post-traumatic symptoms but does not by itself establish a diagnosis of Post-Traumatic Stress Disorder.
Interpretation is most appropriate when combined with clinical interviews, personal history, and other validated psychological assessment tools.
