Traumatic stress disorder: diagnostic and clinical issues in former prisoners of war

Reported Methods, Distributions, and Frequencies of Torture Globally: A Systematic Review and Meta-Analysis

Importance

Despite its prohibition by the United Nations Convention against Torture and other international treaties, torture has been perpetrated against countless individuals worldwide, and health care practitioners globally are increasingly encountering refugee torture survivors in their clinical practices. The methods, geographic distribution, and frequency of torture globally are not well described, which limits health care practitioners' ability to adequately diagnose and treat the sequelae of torture.

Objective

To rank the commonness of torture methods and identify the regions of the world with which they are associated.

Data Sources

For this systematic review and meta-analysis, Ovid MEDLINE, Ovid Embase, Web of Science, and The Cochrane Library were searched from inception to July 2021.

Study Selection

Included studies were peer-reviewed articles in English, contained an independent sample population of individuals who experienced torture, and outlined the type(s) of torture experienced. Excluded studies were not peer reviewed, lacked an independent sample population, or did not specify torture methods. Articles were chosen for inclusion by 2 independent and blinded reviewers, and a third, independent reviewer resolved discrepancies. Overall, 266 articles-15.3% of the 1739 studies initially identified for full review-met the inclusion criteria.

Data Extraction and Synthesis

Data abstraction and quality assessment followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were extracted by 2 independent and blinded reviewers into predefined templates, and a third, independent reviewer resolved discrepancies. The risk of bias was evaluated using the Downs and Black Checklist.

Main Outcomes and Measures

Torture methods were ranked by their average frequencies, numbers of reporting studies, and numbers of countries wherein the methods occurred.

Results

A total of 9937 titles and abstracts were screened, and 266 studies encompassing 103 604 individuals (13 350 men, 5610 women, and 84 644 unspecified) were analyzed. Torture was reported for 105 countries; 21 methods accounted for 84% of all reported methods and 10 methods accounted for 78% of all physical tortures. The top 3 methods were beating or blunt-force trauma (reported in 208 studies and 59 countries; average frequency, 62.4%; 95% CI, 57.7%-67.1%), electrical torture (reported in 114 studies and 28 countries; average frequency, 17.2%; 95% CI, 15.0%-19.4%), and starvation or dehydration (reported in 65 studies in 26 countries; average frequency, 12.7%; 95% CI, 10.2%-15.2%). According to the Downs and Black appraisal tool, 50 studies were rated as good or excellent and 216 as fair or poor.

Conclusions and Relevance

The findings of this study suggest that torture remains widespread. Although innumerable torture methods exist, a limited number account for the vast majority of reported tortures. So that targeted therapies may be developed, additional investigation is needed to better elucidate the sequelae associated with the most common torture methods, described here.

Trajectories of suicidal ideation and posttraumatic stress symptoms among former prisoners of war: a 17-year longitudinal study

War captivity is one of the most severe human-inflicted traumatic experiences with wide and substantial long-term negative effects. However, only one retrospective study examined suicidal ideation (SI) among ex-prisoners of war (ex-POWs). This study aimed to prospectively assess SI among ex-POWs and its associations with posttraumatic stress disorder (PTSD) symptoms over a 17-year period. Two groups of male Israeli veterans from the 1973 Yom Kippur War were examined: ex-POWs and comparable veterans who were not taken captive. Both groups were assessed via self-report measures of SI and PTSD symptoms at three time points: T1 18 (1991), T2 30 (2003), and T3 35 (2008) years after the war. Latent growth curve modeling (LGM) results showed that ex-POWs reported higher levels of SI at T2 and T3 and a pattern of increase in SI levels trajectory over time, compared to control veterans. Furthermore, among ex-POWs, PTSD symptoms at T1 contributed to the increase in rate of change in SI overtime. In addition, PTSD symptoms affected SI at the same measurement, above and beyond above the trajectories of SI. Clinical implications of these findings for the relations between captivity trauma and suicidality are discussed.

Assaultive Projective Identification and the Plundering of the Victim's Identity

A destructive mode of projective identification is delineated: a predator's catastrophic attack calculated to cause the victim a stress disorder marked by a disarrayed identity. This discomposure enables the perpetrator to aggrandize a manifold inroad upon the victim's identity to imprint, intrude, mingle and/or lodge his representation into it; to ravage, steal from, impoverish, and/or corrupt it; finally to have his representation emerge as an internal regulator of the traumatized prey's functioning. The victim's debased integrity is manifest in the symptoms of his ensuing posttraumatic stress disorder (PTSD).

The long-term consequences of war: the experience of World War II

Seven hundred and thirty-one World War II and Korean War veterans completed a questionnaire about their experiences and their current psychological reactions to the war. Nineteen percent scored above the cut-off points for both the General Health Questionnaire and the (war-related) Impact of Event Scale, demonstrating that, even over 50 years after the event, many veterans still experience problems relating to their war experiences. Psychological distress was in part directly related to particular experiences, but intrusion and avoidance both played an important role as mediating variables. Other factors, such as prisoner of war (POW) status, type of service, rank, and illness were also considered. The findings indicate that the effects of a traumatic experience such as war can persist into later life.

The dose-effect relationships between torture and psychiatric symptoms in Vietnamese ex-political detainees and a comparison group

The purpose of this study was to determine in Vietnamese ex-political detainees newly arrived into the United States a) the prevalence of torture and psychiatric symptoms and b) the dose-effect relationships between cumulative torture experience and the psychiatric symptoms of posttraumatic stress disorder (PTSD) and major depression. The study population included Vietnamese ex-political detainees (N = 51) and a comparison group (N = 22). All respondents received culturally validated instruments with known psychometric properties including Vietnamese versions of the Hopkins Symptom Checklist-25 and the Harvard Trauma Questionnaire. The ex-political detainees, in contrast to the comparison group, had experienced more torture events (12.2 SD = 4.2 vs. 2.6 SD = 3.1) and had higher rates of PTSD (90% vs. 79%) and depression (49% vs. 15%). Dose-effect relationships between cumulative torture experience and psychiatric symptoms were positive with the PTSD subcategory of "increased arousal" revealing the strongest association. These findings provide evidence that torture is associated with psychiatric morbidity in Vietnamese refugees. The demonstration of significant dose-effect responses supports the hypothesis that torture is a major risk factor in the etiology of major depression and PTSD. The generalizability of these results to other torture survivor groups is unknown. The interaction between torture and other pre- and post-migration risk factors over time in different cultural settings still needs to be examined.

Suicidal behavior after severe trauma. Part 1: PTSD diagnoses, psychiatric comorbidity, and assessments of suicidal behavior

The study comprises 149 refugees from various countries, reporting exposure to severe traumata, who were referred for psychiatric diagnosis and assessment of suicide risk. The stressors reported comprised both personal experience of and/or forced witnessing of combat atrocities (including explosions or missile impacts in urban areas), imprisonment (including isolation), torture and inflicted pain, sexual violence, witnessing others' suicide, and of summary and/or mock executions. Posttraumatic stress disorder (PTSD) was diagnosed in 79% of all cases, other psychiatric illness in 16% and no mental pathology in 5%. The prevalence of suicidal behavior was significantly greater among refugees with principal PTSD diagnoses than among the remainder. PTSD patients with depression comorbidity reported higher frequency of suicidal thoughts; PTSD nondepressive patients manifested increased frequency of suicide attempts.

The Sonda Project: prevention, prediction, and psychological disorder

The Sonda Project began in Italy in 1985 and was created by Semeion Research Center of Sciences of Communication. It has been operating in approximately 30 Italian cities, ranging from large to small, since 1986. The aim of the Sonda Project is to undertake primary prevention measures at the level of personality organization disorder. Cognitive and communication disorders are, in the context of the Sonda Project, the common ground for many expressions of cultural disorders labeled drug addiction, alcoholism, violence, etc. From the point of view of the Sonda Project, measures aimed at combating drug-addiction and alcoholism are no more than superficial strategies incapable of dealing with the causes of self and hetero-destruction (of others). Such abuses are the most evident political symptoms. The methodological aim of the Sonda Project, therefore, consists in understanding, predicting, and acting upon the incubation disorder of human beings; a disorder which subsequently transforms itself into more or less recognizable symptoms. In order to attain its aim, the Sonda Project has made use of two instruments: 1) a series of Intelligent Computerized Observatories, able to predict, in each community, the typology of people who are more likely to exhibit forms of destructive suffering; 2) a local team able to use such advanced technology and able to utilize territorial activation techniques. These are designed to reinsert into the arena of the social game those people who are more "at risk" in terms of self and heterodestruction, and who are most exposed to psychological and sociological levels of relational "fatigue."

Post-traumatic stress disorder in prisoners of war and combat veterans of the Dieppe Raid: a 50-year follow-up

OBJECTIVE

This paper presents the first 50-year study of the differential effects of incarceration and combat on the development and persistence of post-traumatic stress disorder (PTSD) in Canadian veterans and prisoners of war (POWs) from the Dieppe Raid.

METHOD

A large sample of Dieppe POWs and nonPOWs completed a questionnaire diagnosing PTSD and other psychological and health problems of the veterans in 1946 and in 1992.

RESULTS

The POWs showed a higher incidence of PTSD and other psychological symptoms than veterans with the same combat exposure. The POWs' experiences of malnutrition, maltreatment and torture, and mental suffering showed strong links to PTSD.

CONCLUSIONS

For many veterans, PTSD has lasted 50 years. Failure to be eligible for psychological disability pensions demonstrates that PTSD and other psychological disorders in these veterans have been greatly unrecognized by the Canadian Department of Veteran's Affairs.

Validation of PTSD measures for older combat veterans

This study evaluated three nosologically similar older groups (Older PTSD, POW, and Older Psychiatric) and a group of Younger PTSD veterans from Vietnam. Group membership was derived from index admission diagnoses and clinical validation of status. Groups were compared on the MMPI, PTSD measures, background variables, health measures and an outcome measure. Results showed that the Older PTSD group is closer to the Younger PTSD group than to the other groups on the MMPI and PTSD measures and also that members of this group remain in the hospital longer than do members of the other older groups. Parameters of effective test classification showed the PTSD measures to be helpful in correct identification of this disorder for the older groups.
