Traumatic life events and posttraumatic stress disorder among Mexican adolescents: results from a survey

Community trauma exposure and post-traumatic stress disorder in Chinese children and adolescents

Background

An increasing number of studies have shown the association between traumatic events occurring in childhood and adolescence and post-traumatic stress disorder (PTSD). A gap remains in the literature on the epidemiology and influencing factors of traumatic events and post-traumatic stress disorder in communities in northern China. This study aimed to determine the prevalence of traumatic events and PTSD in communities in northern China, to explore the types of stressful traumatic events and the impact of these traumatic events on children and adolescents, and to investigate the effect of sociodemographic factors on PTSD.

Methods

A cross-sectional survey study was conducted among 6,027 students (7-17 years old) from 6 cities in Liaoning Province, China. The sample consisted of 2,853 males (47.34%) and 3,174 females (52.66%). The Essen Trauma-Inventory for Children and Adolescents (ETI-CA) Scale was used. The ETI-CA has 5 sections, which include type of traumatic events, worst traumatic event, post-traumatic symptoms, onset, duration, burden of PTSD, and present difficulties in different areas of life. PTSD symptoms were assessed with 23 items in Part 3 of the ETI-CA.

Results

We found that 2,068 (34.3%) of 6,027 participants experienced trauma events and 686 (33.2%) of 2,068 reported PTSD. Among trauma-exposed youth (2,068), the sudden death of close relatives (33.9%), serious accidents (20.9%), and parental divorce (15.5%) were reported as the worst traumatic events. Studies have shown that after exposure to stressful life events, more than 30% of people feel nervous or upset (39.8%), scared (33.4%), helpless (32.6%), and about 10% have headaches (15.5%), rapid heartbeat (13.3%), and dizziness (11.8%). Multivariable logistic regression analyses showed that students in middle school [OR = 1.29 (1.016, 1.637)], not a student leader [OR = 0.738 (0.618, 0.881)], and their parents in single marital status significantly predicted higher PTSD prevalence the remarried [OR = 0.474 (0.252, 0.893)], married [OR = 0.42 (0.227, 0.778)].

Conclusion

The present study suggests the government to train psychological counselors in schools and communities to provide emotional and psychological support, as well as the school leaders and parents to elevate adolescents' psychological suzhi. Particularly, counseling and professional support should be given to those students whose parents are single.

Traumatic life-events and suicidality among Mexican adolescents as they grow up: A longitudinal community survey

OBJECTIVE

Limited research exists on the impact of type and number of traumatic events on the incidence of suicide ideation and attempts (suicidality) among adolescents in low/middle income countries where violence is common.

METHOD

We estimated prospective associations of 7 types of events on the new occurrence of suicidality from a follow-up conducted in 2013 (n = 1071; ages 19-26) of the original Mexican Adolescent Mental Health Survey conducted in 2005 (ages 12-17), by using Hazard Ratios (HR) estimates.

RESULTS

For new onset of suicide ideation, those reporting "Ever raped or sexually assaulted" had the highest adjusted HR (3.8), followed by "Ever other traumatic event" (HR = 1.9), "Ever committed or witnessed violence" (HR = 1.7) and "Beaten as a child or witnessed physical fights at home" (HR = 1.5). For suicide attempt, those reporting "Ever beaten up by spouse, partner, someone else, mugged with a weapon, or stalked" (HR = 3.8) and "Ever other traumatic event" (HR = 2.0) had the higher hazards. Compared to those without a traumatic event, increased hazards of ideation and attempt were found for those reporting a greater number of types of events.

CONCLUSIONS

Our sample is representative of the largest metropolitan area in Mexico but does not include other cities or age groups that may differ in risk factors. Traumatic events that happened in the eight years between waves are not considered. Traumatic events increased the risk of suicidality, independent of common mental disorders. Identifying and addressing these events in clinical settings may therefore be important for preventing suicide in this population.

Incidence and recurrence of depression from adolescence to early adulthood: A longitudinal follow-up of the Mexican Adolescent Mental Health Survey

BACKGROUND

Depression is a leading cause of disease burden around the globe, often develops during adolescence and is recurrent. Thus, disentangling risk factors for incidence from those of recurrence during adolescence is relevant and might suggest different strategies for prevention of onset than for relapse. The aim was to evaluate the relative risk of socio-demographic and clinical factors and traumatic events associated to incidence and recurrence of depression in youth from Mexico City.

METHODS

This is a prospective longitudinal general population survey in which 1071 respondents from the Mexican Adolescent Mental Health Survey were interviewed between the ages of 12 and 17 and again eight years later when they were between 19 and 26 years of age. The World Mental Health Composite International Diagnostic Interview evaluated incidence and persistence of major depression and risk factors.

RESULTS

Eight-year incidence was 12.9% while recurrence was 46.1%. Risk factors for incidence (female sex, any incident trauma, and specifically sexual abuse and an other/private event) differed from the risk factors for recurrence (childhood onset and domestic violence) with the exception of having a parent with depression, which was associated to increased risk for both.

LIMITATIONS

The follow-up response rate was limited by inability to locate participants at wave II. Statistical power was limited for persistence due to low rate of depression at wave I.

CONCLUSIONS

Intervening with both depressed and non-depressed children of parents with depression may have beneficial effects on both the development of depression as well as recurrence.

Victimización directa e indirecta y síntomas de estrés postraumático en estudiantes universitarios del Noreste de México

En México, sobre todo en los estados del noreste del país, en los últimos años la violencia se ha exacerbado y, a su vez, ha incrementado sus implicaciones en la salud mental de los jóvenes, principalmente con el desarrollo de síntomas del trastorno por estrés postraumático (TEPT). Teniendo esto en cuenta, en el presente estudio se tuvo como objetivo identificar los tipos de victimización (directa o indirecta) que viven los jóvenes universitarios ante la violencia comunitaria, así como determinar los síntomas de estrés postraumático que presentaban, e identificar la relación entre los tipos de victimización y los síntomas del TEPT. En total, participaron 500 jóvenes universitarios de un estado del noreste del país, a quienes se les aplicó la Escala de Victimización y la Escala Breve del Desorden del Estrés Postraumático. Como resultados, los participantes reportaron un promedio de siete sucesos de victimización tanto directa como indirecta, siendo más frecuente la indirecta. Aunque se observa una relación directa e indirecta entre la victimización y la presencia de síntomas del TEPT, solo la victimización indirecta resultó ser una variable predictora de síntomas del TEPT. Se propone que, junto a las políticas de prevención y reducción del delito, deben crearse políticas de reducción del miedo al crimen en la población.

Adolescent Predictors of Incidence and Persistence of Suicide-Related Outcomes in Young Adulthood: A Longitudinal Study of Mexican Youth

In recent years, Mexico has seen one of the largest increases in suicide rates worldwide, especially among adolescents and young adults. This study uses data from the 1,071 respondents who participated in a two-wave longitudinal study when they were between 12 and 17 years of age, and again when they were between 19 and 26 years of age. The World Mental Health Composite International Diagnostic Interview assessed suicidal behavior and DSM-IV mental disorders. We used Cox regressions to evaluate which sociodemographic and psychiatric factors and life events predicted the incidence and remission of suicide ideation, plan, and attempt throughout the 8-year span. The 8-year incidence of suicide ideation, plan, and attempt was 13.3%, 4.8%, and 5.9%, respectively. We found that the number of traumatic life events during childhood, no longer being in school, and tobacco use predicted which adolescents developed suicide behaviors as they transitioned into young adulthood. Psychiatric disorders, particularly anxiety disorders, played a larger role in the persistence of those who already had suicidal behaviors, while behavioral disorders played a role in the transition from ideation to attempt. This distinction may be useful for clinicians to assess the risk of suicide.

[Potentially traumatic events and post-traumatic symptomatology in high school students]

OBJECTIVE

Describe the occurrence of potentially traumatic events (PTE) in high-school students, measure subthreshold post-traumatic symptomatology in those who still experience PTE repercussions and associate the symptomatology with sociodemographic and PTE characteristics.

MATERIALS AND METHODS

Analytic transversal study carried out in a convenience sample of one thousand students from three high schools in the State of Mexico. The Scale for Post Traumatic Stress in University Students was applied. The presence of symptoms, their frequency and their association with explanatory variables was assessed by means of logistic and quantile logistic regression models, respectively.

RESULTS

80% reported PTE. Of this, 79% still experienced current repercussions and almost a half presented symptomatology. Gender, number of events, and PTE characteristics (perceived and grave symptoms) were associated.

CONCLUSIONS

Results suggest to intervene early to reduce the risk of developing a disorder.

The association of nursing care perception with coping skills and posttraumatic growth in mental disorders

WHAT IS KNOWN ON THE SUBJECT?: Although it is well known that coping with mental disorder is a traumatic experience, studies of the relationships between posttraumatic growth and the variables that can affect it are rarely found in the literature. The studies that do exist usually focus on posttraumatic growth after posttraumatic stress disorder has developed as a result of traumatic life events such as earthquakes, wars, accidents or physical disease. In the literature, there exist few studies of patients diagnosed with psychosis. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This study shows that posttraumatic growth can be seen in patients after the diagnosis of mental disorders. Patients who use effective coping methods show more posttraumatic growth. In addition, patients who are satisfied with the nursing care received in the clinic show more posttraumatic growth. This indicates that care delivered by psychiatric nurses contributes to the posttraumatic growth of the patients. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Psychiatric nurses who recognize that suffering a mental disorder is a traumatic experience and that patients can grow from this experience can contribute to the posttraumatic growth of those in their care. When they see signs of posttraumatic growth, nurses can teach patients how to cope with that stress effectively and how to share their feelings, thoughts and experiences related to the situation. In addition, psychosocial interventions such as trauma-focused cognitive behavioural therapy and eye movement desensitization can be used to aid posttraumatic growth.

ABSTRACT

Introduction Although it is recognized that suffering a mental illness is a traumatic experience, the fact that this can lead to posttraumatic growth and the variables that may affect the situation are rarely discussed in the literature. Aim This study was conducted to determine the effects of coping styles and nursing care perceptions on posttraumatic growth in mental disorders. Method The descriptive study was conducted at a psychiatric clinic with a personal information form and three-scale test. Results In the study, completed with 122 psychiatric inpatients, it was found that patients were using effective methods to cope with stress, were satisfied with nursing care and had high posttraumatic growth. Moreover, it was found that effective coping styles and satisfaction with nursing care positively affected the posttraumatic growth level of patients. Discussion The results support the proposition that using effective coping styles and seeking professional support after traumatic life events influence posttraumatic growth levels. Implications for practice Psychiatric nurses should be aware of the fact that developing a mental disorder is a traumatic life event after which posttraumatic growth can occur. They should encourage posttraumatic growth by teaching effective coping methods, providing psychiatric care and using psychosocial interventions such as trauma-focused cognitive behavioural therapy and eye movement desensitization.

Sexual trauma is more strongly associated with tonic immobility than other types of trauma - A population based study

BACKGROUND

Tonic immobility is an involuntary motor and vocal inhibition reaction, considered the last-ditch response of the defensive cascade model. It is elicited in context of inescapable threat and perception of entrapment. Our aim was to investigate the association between different traumatic events and peritraumatic tonic immobility (PTI) in a representative sample of the general population.

METHODS

This is a cross-sectional study of general population from Rio de Janeiro and São Paulo with 3231 victims of traumatic events aged 15-75 years who completed the Tonic Immobility Scale (TIS). We calculated the frequency of the different traumatic events and estimated the mean scores with 95% confidence intervals for each traumatic event, controlling for the potential confounders using multiple linear regression models. Finally, we calculated the proportion of individual scoring zero in TIS for the 16 traumatic events.

RESULTS

PTI scores in child sexual abuse and adult sexual violence were almost twice as high as in other types of traumatic events, even when controlled for gender and educational level. Torture and war also showed high PTI scores, but these were based on very small number of cases and need to be interpreted with caution. Furthermore, victims of sexual trauma had the lowest proportion of individuals with total absence of PTI symptoms.

LIMITATIONS

This is a cross-sectional study and causal inferences must be drawn with caution.

CONCLUSIONS

Peritraumatic tonic immobility is more strongly associated with sexual trauma, particularly in childhood, than to other types of trauma in the general population.

Posttraumatic stress disorder in a nationally representative mexican community sample

This study describes the public health burden of trauma exposure and posttraumatic stress disorder (PTSD) in relation to the full range of traumatic events to identify the conditional risk of PTSD from each traumatic event experienced in the Mexican population and other risk factors. The representative sample comprised a subsample (N = 2,362) of the urban participants of the Mexican National Comorbidity Survey (2001-2002). We used the World Health Organization's Composite International Diagnostic Interview (CIDI) to assess exposure to trauma and the presence of PTSD according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, ) in each respondents' self-reported worst traumatic event, as well as a randomly selected lifetime trauma. The results showed that traumatic events were extremely common in Mexico (68.8%). The estimate of lifetime PTSD in the whole population was 1.5%; among only those with a traumatic event it was 2.1%. The 12-month prevalence of PTSD in the whole population was 0.6%; among only those with a traumatic event it was 0.8%. Violence-related events were responsible for a large share of PTSD. Sexual violence, in particular, was one of the greatest risks for developing PTSD. These findings support the idea that trauma in Mexico should be considered a public health concern.

Interpersonal Violence and its Association with US Migration Desires and Plans among Youths in Guanajuato, Mexico

This study examined interpersonal physical and sexual violence and its association with desires and plans to migrate to the USA among 500 alternative high school students, aged 14-17 years, from Guanajuato, Mexico. Two thirds of the youths had ever experienced interpersonal violence, the most common form being physical fights. More youths, and more boys relative to girls, reported wanting to migrate than planning to migrate. Although those who had experienced interpersonal violence were not more likely to want to migrate to the USA, their odds of planning to migrate were 44% greater. Gender did not moderate the effect of interpersonal violence.

Some considerations on women's mental health in Latin America and the Caribbean

The mental health status of women in Latin America depends on several social determinants: unequal access to education and work and its benefits, as well as exposure to violence and lack of proper reproductive health impinge on women's psychological well-being. A review of the epidemiological studies on mental health in the region shows a paucity of gender disaggregated data which hinders analyses. However, depression and anxiety are twice as prevalent in women, post traumatic stress disorder is common in the regions that have been exposed to political violence, suicide is an important cause of death in the reproductive years and alcohol and drug use are increasing among younger women. Given the current risks for mental health for girls and women in the region, it is important that research in this area be fostered and it is even more important that gender as it relates to health be included in the curricula of health professionals.

Descriptive epidemiology of chronic childhood adversity in Mexican adolescents

PURPOSE

To estimate the prevalence of adversity (neglect and abuse, parental loss, parental psychopathology, economic adversity, and serious physical illness), the interrelatedness of adversities, and their socio-demographic correlates.

METHODS

This is a multistage probability survey of 3005 adolescents aged 12-17 years residing in Mexico City. Youth were administered the computer-assisted adolescent version of the World Mental Health Composite International Diagnostic Interview in their homes. The childhood and posttraumatic stress disorder sections provided information regarding adversity. Descriptive and logistic regression analyses were performed considering the multistage and weighted sample design.

RESULTS

A total of 68% of adolescents have experienced at least one type of chronic childhood adversity, whereas almost 7% have experienced four of more. The most frequent adversity is economic adversity followed by witnessing domestic violence. Boys experience more neglect than girls, and girls experience more sexual abuse than boys. Family dysfunction adversities tend to clump together such that youth exposed to abuse of any form also report witnessing domestic violence and parental mental pathology. Youth whose parents have divorced are likely to experience economic adversity. Parental death is independent of experiencing other childhood adversities. Older adolescents, school drop-outs, those with young mothers, those with more siblings, and those whose parents have less education are more likely to experience adversity.

CONCLUSIONS

Although most adolescents have experienced some adversity, a small group is exposed to many adversities. Understanding the distribution of adversities may help us to identify at-risk youth and to better interpret the findings from studies on the role of adversity in diverse health outcomes.
