The Impact

The goal of the present report is to validate the Impact of Event Scale for use as a measure of the enduring nature of reactions to combat stress by 60 American Vietnam veterans. Validity was supported through significant correlations with measures of abusive violence and combat exposure. From factor analysis a single factor (general level of distress) supported the validity of the scale and thereby further use with Vietnam veterans.

The Impact

Background. The Impact of Event Scale-Revised (IES-R) is often used as a  self-report instrument for symptoms of post-traumatic stress (PTS). The objective of this study was to explore the reliability and validity of the Lithuanian IES-R in a sample of employees with exposure to workplace bullying in different occupations. Materials and methods. The  original IES-R was translated into Lithuanian, and the  comparability of content was verified through back-translation procedures. 294 employees with exposure to workplace bullying (52 teachers from the secondary schools of Kaunas, 56 family physicians, 101 nurses of internal medicine departments, 40 waiters, and 45 seafarers) were administered the  Lithuanian IES-R and the  General Health Questionnaire  –  12 (GHQ-12) in order to verify some aspects of convergent validity. The  exploratory factor analysis was used to verify the construct validity of the IES-R. Results. The reliability of the Lithuanian version of the IES-R was verified. Cronbach’s α of the total scale was 0.95. Exploratory factor analysis showed a clear factor structure with three independent dimensions: intrusion, avoidance and hyperarousal. Cronbach’s α for subscales of intrusion, avoidance and hyperarousal were 0.89, 0.85, and 0.88, respectively. The convergent validity was supported by positive correlations between the subscales (intrusion, avoidance, hyperarousal) and the GHQ-12. Conclusions. The results suggest that the self-reported Lithuanian IES-R is a valid instrument for assessing the dimensions of post-traumatic stress, has good psychometric properties, and may be applied in prolonged trauma-exposed populations.

Traumatic Symptoms

AbstractThis study explored possible identification of Perpetration-induced Traumatic Stress (PITS) in workers whose occupations required euthanizing nonhuman animals and determining whether event or person-related factors influenced symptoms. The sample included 148 animal workers: veterinarians, veterinary nurses, and research and animal shelter staff. The Impact of Event Scale-Revised (IES-R) assessed traumatic stress. Experimenters constructed additional scales measuring satisfaction with social support, participation in various types of training, and concern over animal death. More than 70% of participants reported affinity toward animals had strongly influenced their occupation selection. Half the sample perceived animal death—particularly euthanasia—as one of the least desirable jobs. Of the sample, 11% reported experiencing moderate levels of traumatic symptoms. The study found lower levels of euthanasia-related stress were associated with increased satisfaction with social support and length of time working with animals. Those who reported high levels of concern about animal death reported higher levels of euthanasia-related stress. The study found occupational context was not associated with different levels of euthanasia-related stress symptoms—even though reasons for administering euthanasia differed significantly between occupations.

The Impact

Construct validity established for the Impact of Event Scale does not include evidence that the scale can distinguish genuine responses from simulated ones, an important requirement for cognitively “transparent” measures subject to systematic distortion by demand characteristics of the test situation. Comparison scores from 35 students coping with recent parental death and 30 randomly selected students instructed to respond as though they recently had a parent die indicated that, as predicted for this measure, simulated responses involved uniformly high endorsement of all items, while genuine responses were lower in magnitude and varied more from item to item. The scale appears to be adequately sensitive to differences between genuine and simulated responses.
