Relationship between exercise intensity and stress levels among U.S. medical students

BACKGROUND

Physical activity may protect the mental health of medical students, yet it is unknown which types and intensities of physical activity have the greatest potential to improve medical student well-being.

OBJECTIVE

We characterize the relationship between exercise intensity and stress levels of U.S. medical students, thereby informing the design of future well-being interventions.

DESIGN

Two cross-sectional validated surveys assessing stress and physical activity were administered one year apart at the David Geffen School of Medicine at UCLA. A total of 1,046 out of 1,392 medical students responded (75%). An ordered logistic regression was used to determine the association between stress and each level of exercise intensity (inactivity, moderate-activity, and health-enhancing physical activity [HEPA]). These exercise intensity groupings were compared to the CDC guidelines for aerobic exercise.

RESULTS

While achieving either moderate-activity or HEPA is compliant with the CDC guidelines for aerobic exercise, the additional intensity of exercise required to achieve HEPA was associated with a 26% increase in the probability of being in the lowest stress quartile and a 22% decrease in the probability of being in the highest stress quartile. Medical student physical activity levels were on-par with the national average per the CDC exercise guidelines (65% vs. 58%), but medical student HEPA levels were significantly lower than the national average (27% vs. 64%; OR 0.21; 95% CI 0.12-0.37).

CONCLUSIONS

There is a large disparity in rates of the highest intensity physical activity (HEPA) between medical students and the age-adjusted national average, which has previously been overlooked by the binary CDC exercise guidelines. The fact that HEPA levels are not optimized and more strongly associated with lower stress levels relative to less intense forms of exercise makes it a promising new target for future well-being interventions among medical trainees.

Religion and Spirituality: Why and How to Address It in Clinical Practice

Religion and spirituality (R/S) have been influential in societies' history, daily life, and identity in the past and in today's society. From a sociological perspective, R/S contributes to family development and organization, influences culture, and often contributes to forming opinions, beliefs, and concepts about oneself, family, society, and the world. In addition, R/S help shape individuals, families, and communities' ethical and moral understanding, thus influencing their behavior. This review article aims to provide the clinician with tools to understand, assess, and provide interventions that consider the patients' and their families' R/S. A recent review of the topic focused on general aspects of the R/S but we are unaware of reviews that integrate attachment, moral foundation theory, and forgiveness. This review will integrate these additional features into our understanding of the role of R/S in the delivery of mental health.

Engaging Latino Adolescent and Young Adult (AYA) Cancer Survivors in Their Care: Piloting a Photonovela Intervention

Latino adolescent and young adult (AYA) cancer survivors represent a growing population given the changing demographics in the USA. They experience significant healthcare disparities and barriers that warrant age-specific and culturally appropriate interventions to improve their clinical and psychosocial outcomes. This single-arm pilot study evaluated a novel intervention - a photonovela - on its ability to educate Latino AYA survivors and their family members and engage them in survivorship care. Ninety-seven participants (Latino AYA survivors and their family members) were recruited for this study. Three surveys assessing survivorship care confidence, cancer stigma, and survivorship care knowledge were administered to families before they received the photonovela, after the intervention, and at a booster phone call session. Mixed effects models were used to evaluate differences in scores at the three time points while accounting for repeated measures and family clustering. Results show that the photonovela was effective in improving survivorship care confidence and knowledge of Latino AYA survivors and their families. This pilot study indicates that the photonovela has potential to be a useful intervention for improving confidence and knowledge regarding the need to seek survivorship care for Latino AYA cancer survivors.

The impact of caregiver post-traumatic stress and depressive symptoms on pediatric transplant outcomes

PTSS as well as symptoms of depression have been reported in children who experience a serious medical adversity as well as their caretakers. The adverse effects of PTSS, when experienced by the patients, on medical outcomes have been clearly documented. However, the impact of those symptoms, if any, when experienced by the caretakers on child outcomes has not been investigated prospectively. We evaluated whether caregiver PTSS and depression symptoms predict adherence to medications and medical outcomes in a prospective multisite study. Four hundred children participated in MALT. Caretaker PTSS were assessed by the IES and depressive symptoms by CES-D. During 2 years of follow-up, the MLVI was used to determine adherence. Centrally read, biopsy-confirmed organ rejection was the primary medical outcome. IES scores were not associated with either adherence or rejection outcomes. In contrast, there were significant correlations between CES-D (depression) scores and lower adherence, r = .13, P < .001, and a trend toward higher scores on the CES-D among those whose children had experienced rejection, 12.4 (SD = 10.9) versus 9.1 (SD = 8.6), P = .077. Caregivers' PTSS were not a risk factor for poor child outcomes in this cohort, whereas depression symptoms were associated with non-adherence and possibly increased rates of rejection. Further study can validate if caregivers' depression as opposed to PTSS confers greater risk and should be a focus during the clinical care of medically ill children.

The use of mobile technology and peer navigation to promote adolescent and young adult (AYA) cancer survivorship care: results of a randomized controlled trial

PURPOSE

Adolescent and young adult (AYA) cancer survivors experience unique barriers that compromise receipt of survivorship care; therefore, development of innovative educational interventions to improve rates of AYA survivorship care is needed. The efficacy of text-messaging and peer navigation interventions was compared to standard-of-care survivorship educational materials to increase AYAs' (1) late effects knowledge and (2) knowledge, attitudes, and self-efficacy towards seeking survivor-focused care.

METHODS

This was a three-armed, prospective, randomized controlled trial with one control group and two intervention groups. The control group received current standard-of-care educational materials. One intervention group participated in a text-messaging program, and the second participated in a peer navigator program. Participants completed pre- and post-intervention questionnaires. Study outcome variables were quantified using Fisher exact tests, two-sample t tests, exact McNemar tests, conditional logistic regression models, and analysis of covariance.

RESULTS

Seventy-one survivors completed the study (control n = 24; text-messaging n = 23; peer navigation n = 24). Late effects knowledge was high at baseline for all groups. The text-messaging group had increased survivorship care knowledge compared to the control group (p < 0.05); the peer navigation group had increased survivorship care self-efficacy compared to the control group; p < 0.05. Both intervention groups showed increased attitudes towards seeking survivor-focused care compared to the control group (text-messaging p < 0.05; peer navigation p < 0.05).

CONCLUSIONS

Each intervention demonstrated significant benefits compared to the control group.

IMPLICATIONS FOR CANCER SURVIVORS

Given the preliminary effectiveness of both interventions, each can potentially be used in the future by AYA cancer survivors to educate and empower them to obtain needed survivorship care.

Alcohol consumption behaviors and neurocognitive dysfunction and emotional distress in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

AIMS

To estimate the level of alcohol consumption behaviors in adult survivors of childhood cancer and to test associations between alcohol consumption behaviors and symptoms of neurocognitive impairment and emotional distress.

DESIGN

Retrospective cohort study with longitudinal follow-up of self-reported health outcomes.

SETTING

Childhood Cancer Survivor Study (CCSS), a 26-center study of ≥ 5-year survivors of childhood cancer diagnosed ≤ 21 years of age between 1970 and 1986 in the United States and Canada.

PARTICIPANTS

A total of 4484 adult survivors of childhood cancer [mean (standard deviation) age at evaluation = 34.8 (6.1) years; time from diagnosis = 24.8 (4.4) years] and 1651 sibling controls who completed surveys reporting on alcohol use, neurocognitive impairment and emotional distress.

MEASUREMENTS

Survivor report of alcohol use included age at drinking initiation and quantity and frequency of alcohol consumption. Neurocognition was assessed using the CCSS Neurocognitive Questionnaire. Emotional distress symptoms were measured using the Brief Symptoms Inventory-18 and the Posttraumatic Stress Diagnostic Scale.

FINDINGS

After adjustment for childhood cancer treatment exposures, including cranial radiation therapy, drinking initiation prior to 18 years of age was associated with 30% increased risk of subsequent memory problems [risk ratio (RR) = 1.3; 95% confidence interval (CI) = 1.1-1.5]. Younger age at drinking initiation was associated with future risk of depression (RR = 1.3; 95% CI = 1.1-1.5), anxiety (RR = 1.6; 95% CI = 1.3-2.1), and somatization (RR = 1.2; 95% CI = 1.1-1.4). Persistent heavy/risky drinking was associated with 80% increased risk of persistent psychological distress (RR = 1.8, 95% CI = 1.4-2.3).

CONCLUSIONS

Drinking initiation during adolescence is associated with modest increased risk for memory impairment and emotional distress in adult survivors of childhood cancer.

Self-Management Measurement and Prediction of Clinical Outcomes in Pediatric Transplant

OBJECTIVE

To further refine a measure of self-management, the Responsibility and Familiarity with Illness Survey (REFILS), and to determine if this score predicts medication adherence and, thus, fewer instances of allograft rejection among pediatric liver transplant recipients.

STUDY DESIGN

Participants were 400 liver transplant recipients and their parents recruited for the Medication Adherence in Children Who Had a Liver Transplant study, from 5 US pediatric transplant centers. The REFILS was administered to participants (ages 9-17 years) and their parents at enrollment (n = 213 completed dyads). The REFILS scores, and a discrepancy score calculated between patient and parent report of the patient's self-management, were used to predict Medication Level Variability Index (MLVI), a measure of medication adherence (higher MLVI = more variability in medication levels) and central pathologist-diagnosed rejection over a 2-year follow-up.

RESULTS

When patients reported greater self-management, their adherence was lower (higher MLVI, r = 0.26, P < .01). Discrepancies between patient and parent report (patients endorsing higher levels than parents) were associated with lower adherence (r = 0.20, P < .01). Greater patient-reported self-management and higher discrepancy scores also predicted rejection.

CONCLUSIONS

We found that when patients endorse more responsibility for their care, clinical outcomes are worse, indicating that indiscriminate promotion of self-management by adolescents may not be advisable. A discrepancy between patient and parent perception of self-management emerged as a novel strategy to gauge the degree of risk involved in transitioning care responsibilities to the child.

Recruiting a representative sample in adherence research-The MALT multisite prospective cohort study experience

Medication adherence is an important determinant of transplant outcomes. Attempts to investigate adherence are frequently undermined by selection bias: It is very hard to recruit and retain non-adherent patients in research efforts. This manuscript presents recruitment strategies and results from the MALT (Medication Adherence in children who had a Liver Transplant) multisite prospective cohort study. MALT sites recruited 400 pediatric liver transplant patients who agreed to be followed for 2 years. The primary purpose was to determine whether a marker of adherence, the Medication Level Variability Index (MLVI), predicts rejection outcomes. The present manuscript describes methods used in MALT to ensure that a representative sample was recruited, and presents detailed recruitment results. MALT sites were able to recruit a nationally representative sample, as determined by a comparison between the MALT cohort and a national sample of transplant recipients. Strategies that helped ensure that the sample was representative included monitoring of the outcome measure in comparison with a national sample, drastically limiting patient burden, and specific recruitment methods. We discuss the importance of a representative sample in adherence research and recommend that future efforts to study adherence pay special attention to sample characteristics.

Medical Student Perceptions of the Learning Environment in Medical School Change as Students Transition to Clinical Training in Undergraduate Medical School

Phenomenon: The learning environment is the physical, social, and psychological context in which a student learns. A supportive learning environment contributes to student well-being and enhances student empathy, professionalism, and academic success, whereas an unsupportive learning environment may lead to burnout, exhaustion, and cynicism. Student perceptions of the medical school learning environment may change over time and be associated with students' year of training and may differ significantly depending on the student's gender or race/ethnicity. Understanding the changes in perceptions of the learning environment related to student characteristics and year of training could inform interventions that facilitate positive experiences in undergraduate medical education.

APPROACH

The Medical School Learning Environment Survey (MSLES) was administered to 4,262 students who matriculated at one of 23 U.S. and Canadian medical schools in 2010 and 2011. Students completed the survey at the end of each year of medical school as part of a battery of surveys in the Learning Environment Study. A mixed-effects longitudinal model, t tests, Cohen's d effect size, and analysis of variance assessed the relationship between MSLES score, year of training, and demographic variables.

FINDINGS

After controlling for gender, race/ethnicity, and school, students reported worsening perceptions toward the medical school learning environment, with the worst perceptions in the 3rd year of medical school as students begin their clinical experiences, and some recovery in the 4th year after Match Day. The drop in MSLES scores associated with the transition to the clinical learning environment (-0.26 point drop in addition to yearly change, effect size = 0.52, p < .0001) is more than 3 times greater than the drop between the 1st and 2nd year (0.07 points, effect size = 0.14, p < .0001). The largest declines were from items related to work-life balance and informal student relationships. There was some, but not complete, recovery in perceptions of the medical school learning environment in the 4th year. Insights: Perceptions of the medical school learning environment worsen as students continue through medical school, with a stronger decline in perception scores as students' transition to the clinical learning environment. Students reported the greatest drop in finding time for outside activities and students helping one another in the 3rd year. Perceptions differed based on gender and race/ethnicity. Future studies should investigate the specific features of medical schools that contribute most significantly to student perceptions of the medical school learning environment, both positive and negative, to pinpoint potential interventions and improvements.

Complementary Therapies and Childhood Cancer

BACKGROUND

The use of complementary and alternative therapies by children with cancer is common. Up to 84% of children have used complementary therapies along with conventional medical treatment for cancer.

METHODS

We reviewed the PubMed and CINAHL databases for studies published between 1994 and 2004 on the use of complementary and alternative therapies by children with cancer and reports from any publication year through 2004 of clinical trials involving complementary and alternative therapies for children with cancer.

RESULTS

Fourteen studies were retrieved reporting the results of survey or interview data collected from parents on children's use of complementary and alternative therapies during or after childhood cancer. Across studies, the use of such therapies ranged from 31% to 84%. Common reasons for using complementary and alternative therapies were to do everything possible for their child, to help with symptom management, and to boost the immune system. Many parents indicated they also hoped to treat or cure the cancer. In most cases, the child's treating physician had not been informed of the child's use of complementary and alternative therapies.

CONCLUSIONS

Use of complementary therapies by children with cancer is common, although methodological variations limit the ability to compare results across studies. Treating physicians often do not know the child is using complementary therapies in addition to medical treatments. The scientific evidence is limited regarding the effects and mechanisms of action of complementary or alternative therapies, but research is being conducted on these topics.

Assessing the Learning Environment for Medical Students: An Evaluation of a Novel Survey Instrument in Four Medical Schools

OBJECTIVE

A practical, reliable, and valid instrument is needed to measure the impact of the learning environment on medical students' well-being and educational experience and to meet medical school accreditation requirements.

METHODS

From 2012 to 2015, medical students were surveyed at the end of their first, second, and third year of studies at four medical schools. The survey assessed students' perceptions of the following nine dimensions of the school culture: vitality, self-efficacy, institutional support, relationships/inclusion, values alignment, ethical/moral distress, work-life integration, gender equity, and ethnic minority equity. The internal reliability of each of the nine dimensions was measured. Construct validity was evaluated by assessing relationships predicted by our conceptual model and prior research. Assessment was made of whether the measurements were sensitive to differences over time and across institutions.

RESULTS

Six hundred and eighty-six students completed the survey (49 % women; 9 % underrepresented minorities), with a response rate of 89 % (range over the student cohorts 72-100 %). Internal consistency of each dimension was high (Cronbach's α 0.71-0.86). The instrument was able to detect significant differences in the learning environment across institutions and over time. Construct validity was supported by demonstrating several relationships predicted by our conceptual model.

CONCLUSIONS

The C-Change Medical Student Survey is a practical, reliable, and valid instrument for assessing the learning environment of medical students. Because it is sensitive to changes over time and differences across institution, results could potentially be used to facilitate and monitor improvements in the learning environment of medical students.

Implementation of interprofessional education (IPE) in 16 U.S. medical schools: Common practices, barriers and facilitators

BACKGROUND

Enhanced patient outcomes and accreditation criteria have led schools to integrate interprofessional education (IPE). While several studies describe IPE curricula at individual institutions, few examine practices across multiple institutions.

PURPOSE

To examine the IPE integration at different institutions and determine gaps where there is potential for improvement.

METHOD

In this mixed methods study, we obtained survey results from 16 U.S. medical schools, 14 of which reported IPE activities.

RESULTS

The most common collaboration was between medical and nursing schools (93%). The prevalent format was shared curriculum, often including integrated modules (57%). Small group activities represented the majority (64%) of event settings, and simulation-based learning, games and role-play (71%) were the most utilized learning methods. Thirteen schools (81.3%) reported teaching IPE competencies, but significant variation existed. Gaps and barriers in the study include limitations of using a convenience sample, limited qualitative analysis, and survey by self-report.

CONCLUSIONS

Most IPE activities focused on the physician role. Implementation challenges included scheduling, logistics and financial support. A need for effective faculty development as well as measures to examine the link between IPE learning outcomes and patient outcomes were identified.

Medical Student Perceptions of the Learning Environment: Learning Communities Are Associated With a More Positive Learning Environment in a Multi-Institutional Medical School Study

PURPOSE

Many medical schools have implemented learning communities (LCs) to improve the learning environment (LE) for students. The authors conducted this study to determine whether a relationship exists between medical student perceptions of the LE and presence of LCs during the preclerkship years.

METHOD

Students from 24 schools participating in the American Medical Association Learning Environment Study completed the 17-item Medical Student Learning Environment Survey (MSLES) at the end of their first and second years of medical school between 2011 and 2013. Mean total MSLES scores and individual item scores at the end of the first and second years in schools with and without LCs were compared with t tests, and effect sizes were calculated. Mixed-effects longitudinal models were used to control for student demographics and random school and student effects on the relationship between LC status and MSLES score.

RESULTS

A total of 4,980 students (81% of 6,148 matriculants) from 18 schools with LCs and 6 without LCs participated. Mean [SD] MSLES scores were significantly higher in LC schools compared with non-LC schools at the end of year one (3.72 [0.44] versus 3.57 [0.43], P < .001) and year two (3.69 [0.49] versus 3.42 [0.54], P < .001). The effect size increased from 0.35 (small) at the end of year one to 0.53 (medium) at the end of year two.

CONCLUSIONS

This large multi-institutional cohort study found that LCs at medical schools were associated with more positive perceptions of the LE by preclerkship students.

PTSD in solid organ transplant recipients: Current understanding and future implications

PTSS are quite prevalent in transplant recipients, although full-scale PTSD may not be that common. Those symptoms have been linked to poor transplant outcomes, perhaps owing to non-adherence to medications and other recommendations, brought about by the avoidance dimension of the PTSD/PTSS construct (patients may avoid taking their medications because they serve as reminder of the emotionally traumatic event--the transplant). It is possible to treat PTSD via specific psychotherapeutic techniques, and the treatment has been shown to be safe and likely effective in other populations. Therefore, practitioners who treat transplant recipients should be familiar with the presentation and treatment of those symptoms. This manuscript provides a systematic literature review of the PTSD/PTSS presentation in the pediatric transplant setting, a synthesis of available research findings, and suggestions for current care and future research.

Chaplain rounds: a chance for medical students to reflect on spirituality in patient-centered care

OBJECTIVE

This study assesses the perceived impact of a required half-day with a hospital chaplain for first-year medical students, using a qualitative analysis of their written reflections.

METHODS

Students shadowed chaplains at the UCLA hospital with the stated goal of increasing their awareness and understanding of the spiritual aspects of health care and the role of the chaplain in patient care. Participation in the rounds and a short written reflection on their experience with the chaplain were required as part of the first-year Doctoring course.

RESULTS

The qualitative analysis of reflections from 166 students using grounded theory yielded four themes: (1) the importance of spiritual care, (2) the chaplain's role in the clinical setting, (3) personal introspection, and (4) doctors and compassion.

CONCLUSIONS

Going on hospital rounds with a chaplain helps medical students understand the importance of spirituality in medicine and positively influences student perceptions of chaplains and their work.

Relations between posttraumatic stress and posttraumatic growth in long-term survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

OBJECTIVE

Contemporary models of trauma suggest that posttraumatic stress and growth should be related and that symptoms of stress resulting from a perceived trauma (e.g., childhood cancer) are prerequisite for posttraumatic growth (PTG) to occur. However, empirical data regarding the relationship of posttraumatic stress and growth have been equivocal. The purpose of this study is to examine the relationship between posttraumatic stress symptoms (PTSS) and PTG among adult survivors of childhood cancer.

METHODS

Survey methods were used to collect data from 6,162 survivors participating in the Childhood Cancer Survivor Study (CCSS). Nonparametric correlation was examined pairwise between PTG and PTSS using Spearman's correlation coefficient with 95% confidence intervals, with nonlinear canonical correlation analysis being conducted to examine relationships between subscales. A multivariable partial proportional odds model was also fit for PTG total quartiles focusing on associations with PTSS total quartiles while adjusting for sociodemographic and medical variables.

RESULTS

Examination of unadjusted PTSS and PTG total scores revealed a Spearman correlation of 0.11 (p < .001), with coefficients ranging from 0.03 to 0.17 between total and subscale scores. The nonlinear canonical correlation analyses resulted in two dimensions with eigenvalues of 0.15 and 0.14, resulting in a fit value of 0.30 and evidence that little variability in the data (15%) was explained by the weighted combinations of the variables.

CONCLUSIONS

Although statistically significant, these results do not indicate a robust relationship between PTSS and PTG among adult survivors of childhood cancer. Theories suggesting that PTSS is a prerequisite for PTG should be reconsidered.

Relationship between medical student perceptions of mistreatment and mistreatment sensitivity

BACKGROUND

National statistics reveal that efforts to reduce medical student mistreatment have been largely ineffective. Some hypothesize that as supervisors gain skills in professionalism, medical students become more sensitive.

AIMS

The purpose of this study was to determine if medical student perceptions of mistreatment are correlated with mistreatment sensitivity.

METHOD

At the end of their third year, 175 medical students completed an Abuse Sensitivity Questionnaire, focused on student assessment of hypothetical scenarios which might be perceived as abusive, and the annual Well-Being Survey, which includes measurement of incident rates of mistreatment. It was hypothesized that those students who identified the scenarios as abusive would also be more likely to perceive that they had been mistreated.

RESULTS

Student perceptions of mistreatment were not statistically correlated with individual's responses to the scenarios or to a statistically derived abuse sensitivity variable. There were no differences in abuse sensitivity by student age or ethnicity. Women were more likely than men to consider it "harsh" to be called incompetent during rounds (p < 0.0005).

CONCLUSION

This study provides preliminary evidence that challenges the hypothesis that medical students who perceive mistreatment by their superiors are simply more sensitive.

Improving child and adolescent psychiatry education for medical students: an inter-organizational collaborative action plan

OBJECTIVE

A new Child and Adolescent Psychiatry in Medical Education (CAPME) Task Force, sponsored by the Association for Directors of Medical Student Education in Psychiatry (ADMSEP), has created an inter-organizational partnership between child and adolescent psychiatry (CAP) educators and medical student educators in psychiatry. This paper outlines the task force design and strategic plan to address the long-standing dearth of CAP training for medical students.

METHOD

The CAPME ADMSEP Task Force, formed in 2010, identified common challenges to teaching CAP among ADMSEP's CAPME Task Force members, utilizing focus-group discussions and a needs-assessment survey. The Task Force was organized into five major sections, with inter-organizational action plans to address identified areas of need, such as portable modules and development of benchmark CAP competencies.

RESULTS/CONCLUSION

The authors predict that all new physicians, regardless of specialty, will be better trained in CAP. Increased exposure may also improve recruitment into this underserved area.

Perceived positive impact of cancer among long-term survivors of childhood cancer: a report from the childhood cancer survivor study

OBJECTIVE

Investigations examining psychosocial adjustment among childhood cancer survivors have focused primarily on negative effects and psychopathology. Emergent literature suggests the existence of positive impact or adjustment experienced after cancer, as well. The purpose of this study is to examine the distribution of Perceived Positive Impact (PPI) and its correlates in young adult survivors of childhood cancer.

METHODS

6425 survivors and 360 siblings completed a comprehensive health survey, inclusive of a modified version of the Post-traumatic Growth Inventory (PTGI) as a measure of PPI. Linear regression models were used to examine demographic, disease and treatment characteristics associated with PPI.

RESULTS

Survivors were significantly more likely than siblings to report PPI. Endorsement of PPI was significantly greater among female and non-white survivors, and among survivors exposed to at least one intense therapy, a second malignancy or cancer recurrence. Survivors diagnosed at older ages and fewer years since diagnosis were more likely to report PPI. Income, education and marital/relationship status appeared to have varied relationships to PPI depending upon the subscale being evaluated.

CONCLUSIONS

The existence and variability of PPI in survivors in this study suggest that individual characteristics, inclusive of race, gender, cancer type, intensity of treatment, age at diagnosis and time since diagnosis, have unique and specific associations with different aspects of perceived positive outcomes of childhood cancer.

Psychiatric issues in pediatric organ transplantation

Solid organ transplantation has become the first line of treatment for a growing number of life-threatening pediatric illnesses. With improved survival, research into the long-term outcome of transplant recipients has become important to clinicians. Adherence to medical instructions remains a challenge, particularly in the adolescent population. New immunosuppressant approaches promise to expand organ transplantation in additional directions. Extension of transplantation into replacement of organs such as faces and hands raises complex ethical issues.

Defining medical posttraumatic stress among young adult survivors in the Childhood Cancer Survivor Study

OBJECTIVE

To examine the implications of use of differential thresholds for studying medical Posttraumatic Stress Disorder (PTSD).

METHODS

Self-report data from 6,542 young adult survivors of childhood cancer and 374 of their siblings were used to create clearly differentially defined groups to compare prevalence, correlations and predictors of posttraumatic stress.

RESULTS

Prevalence of posttraumatic stress in survivors compared to siblings differed by definition used, ranging from an odds ratio of 4.21 (95% CI 2.11-8.38) when posttraumatic stress was defined as meeting full symptoms plus functional impairment to 1.42 (95% CI 0.79-2.56) for partial symptoms with functional impairment. Re-experiencing symptoms did not substantially contribute to the ability to identify functional impairment and emotional distress. Although most of the variables associated with posttraumatic stress symptoms and impairment were consistent across definitions of PTSD, marital status and employment demonstrated nonproportional relationships.

CONCLUSIONS

Choice of the definition used in studying posttraumatic stress after serious illness alters not only epidemiological findings, but also associations with correlates and predictors. This is important in the current debate about the criteria for PTSD in the upcoming DSMV. Further study is needed to determine if these findings are applicable to people exposed to other types of traumatic events.

Prevalence and predictors of posttraumatic stress disorder in adult survivors of childhood cancer

OBJECTIVE

This study compared the prevalence of symptoms of posttraumatic stress disorder (PTSD), with functional impairment and/or clinical distress, among very long-term survivors of childhood cancer and a group of healthy siblings.

METHODS

A total of 6542 childhood cancer survivors >18 years of age who received diagnoses between 1970 and 1986 and 368 siblings of cancer survivors completed a comprehensive demographic and health survey.

RESULTS

A total of 589 survivors (9%) and 8 siblings (2%) reported functional impairment and/or clinical distress in addition to the set of symptoms consistent with a full diagnosis of PTSD. Survivors had more than fourfold greater risk of PTSD, compared with siblings (odds ratio [OR]: 4.14 [95% confidence interval [CI]: 2.08-8.25]). With controlling for demographic and treatment variables, increased risk of PTSD was associated with educational level of high school or less (OR: 1.51 [95% CI: 1.16-1.98]), being unmarried (OR: 1.99 [95% CI: 1.58-2.50]), having annual income below $20,000 (OR: 1.63 [95% CI: 1.21-2.20]), and being unemployed (OR: 2.01 [95% CI: 1.62-2.51]). Intensive treatment also was associated with increased risk of full PTSD (OR: 1.36 [95% CI: 1.06-1.74]).

CONCLUSIONS

PTSD was reported significantly more often by survivors of childhood cancer than by sibling control subjects. Although most survivors apparently are faring well, a subset reported significant impairment that may warrant targeted intervention.

Integrating case topics in medical school curriculum to enhance multiple skill learning: using fetal alcohol spectrum disorders as an exemplary case

OBJECTIVES

This article describes the use of fetal alcohol spectrum disorders (FASDs) as a theme to connect the learning of basic neurosciences with clinical applications across the age span within a systems-based, integrated curricular structure that emphasizes problem-based learning.

METHODS

In collaboration with the Centers for Disease Control and Prevention (CDC) and the National Organization on Fetal Alcohol Syndrome, the Western Regional Training Center for Fetal Alcohol Exposure at UCLA developed and integrated educational materials on FASDs into the curriculum for first-year medical students.

RESULTS

Quantitative and qualitative evaluations suggested materials were effective in enhancing student knowledge and skills related to FASDs, as well as embryology, brain development, substance abuse, developmental psychopathology, and medical ethics.

CONCLUSION

The use of a unifying theme integrating basic science and clinical information and skills is effective for medical student training in the prevention and treatment of common medical problems.

Evaluating non-adherence to immunosuppressant medications in pediatric liver transplant recipients

Non-adherence with recommended immunosuppressant medications is common post-pediatric liver transplant and is the most important reason for organ rejection in long-term survivors. However, there is currently no validated, standard method to measure adherence, with a well-defined threshold, making it extremely difficult to evaluate interventions to improve adherence. Previous studies have suggested that the degree of fluctuation of medication blood levels over time can provide an idea about how regularly the medication is being taken. The present study, conducted at UCLA medical center, sought to identify a specific threshold value of the s.d. of individual tacrolimus blood levels in pediatric liver transplant recipients which would be associated with rejection episodes in these patients. A threshold of 3.0 has been identified in other studies, and was supported by the analysis of retrospective data from 96 subjects. However, further analysis found that a s.d. of 2.5 appeared to have a better fit with the data. These findings suggest the utility of monitoring the s.d. of routine tacrolimus blood levels in pediatric liver transplant recipients for detecting non-adherence to immunosuppressant medication prior to clinical rejection, allowing earlier interventions.

Ethics education

This article briefly describes the background and status of medical education in the areas of ethics and professionalism. Methods of teaching and assessment are described for medical students, residents, and practitioners within the core competency framework of medical education. Key areas of content for child and adolescent psychiatrists are described.

Post-traumatic stress response to life-threatening illnesses in children and their parents

Symptoms of PTSD have been reported in response to a variety of life-threatening medical illnesses and injuries in adults and children. Emerging data suggest that children often experience medical treatment and hospitalization as traumatic, putting caregivers and medical personnel in the role of the unintended accomplice. Adequate pain control by pharmacologic and behavioral means; child and family psychological support using evidence-based CBT, dynamic psychotherapy, and other techniques; and meticulous attention to communication via a team-based approach are the cornerstones of pediatric palliative care in general and PTSD prevention and treatment in particular. Emerging evidence suggests that PTSD in life-limiting pediatric illness can be ameliorated, if not prevented, and treated when it occurs, contributing materially to the quality of life of a child and family. A landmark finding of PTSD research with medically ill children and their families is that parents are at least as symptomatic, or more, as their children, underlining the importance of a family-directed approach addressing every family mem-ber. Pediatric caregivers increasingly recognize their therapeutic role when curative therapy is no longer possible is as pivotal as in the setting of acute illness.

The medical traumatic stress toolkit

Children and their parents who are exposed to medical life-threat due to illness or injury are at risk for developing symptoms of posttraumatic stress. However, the prevention, detection, and treatment needed are often not available in the acute care settings of the hospital. The National Child Traumatic Stress Network and the Substance Abuse and Mental Health Services Administration have created a set of materials for use by hospital health providers and families that is available for download free from the National Child Traumatic Stress Network website, www.nctsn.org.

Posttraumatic stress disorder in medically ill patients: what is known, what needs to be determined, and why is it important?

Can a medical illness or its treatment qualify as an emotionally traumatic event and can it cause posttraumatic stress disorder symptoms? If so, can the view of a medical illness as a traumatic experience enhance our ability to understand patients' adjustment to illness and their emotional reactions to it? Is it important to identify posttraumatic symptoms and try to address them in medically ill patients? These questions form the backbone for this review. Because many questions remain unanswered (or the answers are not definitive yet), we concisely summarize the issues and present our own view of the most pressing questions for further research.

Assessment of depression in medically ill children presenting to pediatric specialty clinics

OBJECTIVE

Self-report measures of depression may be inaccurate when applied to medically ill children because of the overlap between medical and psychiatric symptoms. The American Academy of Pediatrics endorses the use of self-reports as diagnostic aids (used in patients who are suspected of having an emotional problem by their pediatricians). This approach has not been validated. We evaluated the diagnostic accuracy of the Children's Depression Inventory (CDI) in medically ill children who were referred for evaluation by their pediatricians.

METHOD

The evaluation included the CDI and a best estimate diagnostic procedure that incorporated results from semistructured and other interviews. Evaluators were not aware of the CDI scores when making a diagnostic determination.

RESULTS

One hundred twenty-five patients, 8-19 years old, were referred between September 2000 and May 2003. Eighty-one completed the diagnostic procedure. The CDI summary score performed well in identifying best estimate depressive disorder determinations in this cohort. A cutoff of 11 and above correctly identified 80% of cases, with a specificity of 70%.

DISCUSSION

A self-report measure of depression (CDI) could be used as a diagnostic aid in medically ill children who are suspected of having an emotional problem by their pediatricians. This finding supports the "two-tier" depression screening approach endorsed by the American Academy of Pediatrics for use in pediatricians' offices.

Traumatic stress symptoms in adolescent organ transplant recipients

OBJECTIVE

Symptoms of posttraumatic stress disorder (PTSD) after life-threatening medical illness have been found to predict poor outcome in preliminary studies of adults and children. However, these symptoms are rarely recognized in general medical or pediatric settings. Here we report on the first large investigation to assess prevalence and correlates of self-reported symptoms of posttraumatic stress in a nonreferred sample of adolescent liver, heart, and kidney transplant recipients.

METHODS

One hundred four adolescents, ages 12 to 20 years (mean: 15.7; SD: 2.1), completed and returned the University of California, Los Angeles, PTSD Index for the Diagnostic and Statistical Manual of Mental Disorders. All participants were at least 1 year post-initial transplant and were fluent speakers of English and/or Spanish.

RESULTS

More than 16% of the adolescents met all symptom criteria for PTSD, and an additional 14.4% met 2 of 3 symptom-cluster criteria. Regression analysis indicated no effect of gender, ethnicity, age at interview, organ type, time since transplant, or age at transplant.

CONCLUSIONS

As has been found with other life-threatening pediatric conditions, solid organ transplantation can precipitate symptoms of posttraumatic stress. Symptoms are not predicted by what would be considered objective factors increasing life threat, suggesting a greater salience of subjective appraisal of threat, as has been seen in studies of childhood cancer survivors.

Preliminary evidence for lymphocyte distribution differences at rest and after acute psychological stress in PTSD-symptomatic women

This study investigated circulating natural killer (NK), CD4+ and CD8+ cells in response to acute psychological challenge among mothers of child cancer survivors with and without posttraumatic stress symptoms (PTSS). Control mothers of healthy children (n=9) were compared to 17 cancer mothers with (PTSS: n=9) and without PTSS (No PTSS: n=7) under conditions of rest, after a generic stressor (MAT: mental arithmetic task) and a personalized stressor (script-driven trauma imagery), and after recovery from each stressor. Results indicate the PTSS group had higher percentage CD4+ and lower CD8+ levels than non-symptomatic women and blunted NK reactivity to generic challenge. Multiple regression analyses indicated PTSS effects were independent of self-reported distress. Contrary to expectations, cancer mothers without PTSS were not significantly different from controls on tonic or phasic immune outcomes. Also unlike predictions, reactivity to challenge was greatest to the non-social MAT stressor compared to the personalized challenge for all groups. Conclusions are constrained by study limitations (e.g., small sample size and potential phase order effects). Nonetheless, results are consistent with an emerging literature on PTSS-associated immune differences and further suggest these effects may be distinct from that associated with subjective distress more generally.

Medication adherence in pediatric and adolescent liver transplant recipients

OBJECTIVE

Nonadherence to medications is a leading cause of morbidity in children and adolescents who have had a transplant, yet there are no published data about the use of different methods for detecting whether these children are taking their medications. There are also no published data about the age of transition at which a child assumes responsibility over taking the medications. This information is important if interventions to improve adherence are contemplated.

METHODS

We present an analysis of data obtained in the first year of the implementation of an adherence assessment protocol at a pediatric liver transplant clinic in a tertiary medical care center. Data were obtained for children and adolescents who had a liver transplant at least 1 year before the assessments took place. We used 5 adherence detection methods. The 4 subjective methods were self-reported, scaled questionnaires answered by nurses, physicians, caregivers, and patients. For the objective method, a standard deviation (SD) was calculated for tacrolimus blood levels obtained from each patient over time. A higher SD suggests increased variation among patients' blood levels and hence more erratic medication taking. We also asked the patients and caregivers who is responsible for taking the medications and what are the reasons for not taking them. The medical outcome measures were biopsy-proven rejection episodes, number of biopsies regardless of the results, number of hospital admissions, and number of in-patient days.

RESULTS

An analysis of 81 cases (258 assessments) revealed that the only method that predicted the medical outcome variables (biopsy-proven rejection and number of biopsies) was the SD of medication blood levels. Patients', clinicians', and caregivers' reports were not predictive. Clinicians' ratings of adherence were not correlated with patients' or caregivers'. The transition of responsibility for medication taking occurred approximately at the age of 12 years. Forgetfulness was cited as the most common reason for nonadherence by patients and caregivers; medication side effects were not frequently cited.

CONCLUSIONS

Our results indicate that clinical impression is not sufficient to determine whether children and adolescents are taking their medications after they have had a liver transplant. An objective assessment method should be used. Interventions targeting adherence should address the child's increasing role beginning in early adolescence. A clinical protocol incorporating objective assessments of adherence could potentially be implemented in other settings. It could form the basis for the evaluation of efficacy of interventions seeking to improve adherence to medications.

Spirituality in children confronting death

This article uses a developmental framework to consider common spiritual issues raised by children and adolescents who are confronting death. The literature exploring the role of children's spirituality in addressing death is used to illustrate specific areas of concern and topics deserving further research. Clinical examples are offered to illustrate the types of situations encountered by mental health professionals dealing with seriously ill children and their families. Recommendations are offered for concrete approaches for mental health professionals dealing with families confronting the death of a child.

Spirituality in children and adolescents: research findings and implications for clinicians and researchers

Spirituality is a powerful force in the lives of children. Although spirituality has only recently begun to be a focus for psychiatric research, initial qualitative data suggest that children experience themselves as spiritual beings and that understanding and connecting with them around their spiritual lives can be an important adjunct to treatment. Clinicians should feel free to ask about a child's spiritual life and to work with the family using their spiritual resources if they are perceived to be beneficial in helping the child and family cope with their current situation. Because the work with children's spirituality is in its preliminary stages, qualitative methodology is still the recommended research method for investigating questions in this research area.

Symptoms of posttraumatic stress disorder in parents of transplant recipients: incidence, severity, and related factors

OBJECTIVE

To examine the incidence, severity, and factors related to posttraumatic stress disorder (PTSD) symptoms in parents of pediatric solid organ transplant recipients.

METHOD

A total of 170 caregivers of pediatric transplant recipients completed self-report measures of psychological functioning between 10 and 38 months after their child's most recent transplant. Demographic data, child health variables, and ratings of medical attitudes and social functioning were also collected to help explain individual differences in psychological functioning.

RESULTS

Although caregivers of pediatric transplant recipients did not report elevated levels of depression or anxiety, they did report elevated levels of PTSD symptoms. Multiple regression analyses revealed that PTSD symptoms were most strongly associated with parent reports of child health, family impact of the transplant, and attitudes toward medical caregivers.

CONCLUSIONS

PTSD seems to be relatively common in parents of pediatric transplant recipients and may be largely the result of how parents perceive and interpret the transplant experience.

Posttraumatic stress responses in children with life-threatening illnesses

Posttraumatic stress symptoms have been reported in response to various serious medical illnesses in adults and children. Not surprisingly, posttraumatic stress is probably more common in response to acute, life-threatening, events that are related to the illness. Emerging data suggest that children often experience life-saving medical procedures as traumatic, which puts caretakers and medical personnel in the role of perpetrators for the children. Trauma symptoms are also reported as common and severe in caregivers. Both of these issues have been previously poorly understood and should be addressed in assessment and treatment. As with other traumatic events, developmental considerations, the nature and severity of the event itself, social supports, and premorbid exposure to negative life events are also important issues to consider in developing appropriate interventions. The importance of developing prevention and treatment for PTSD in medically ill children and adults includes increased morbidity and mortality (e.g., nonadherence to medications) and psychiatric sequelae and decreased quality of life. Obstacles to systematic study of a psychiatric intervention for this group include difficulties assessing multidrug regimens and cognitive treatment effects in this group. The relative stability of social supports and the potential use of preventive measures make this an attractive population for intervention. Clinicians and researchers are encouraged to work together to develop and use uniform screening and assessment methods that will help to identify cases and facilitate the multicenter trials that are vital to increasing knowledge in this patient population.

Posttraumatic stress, quality of life, and psychological distress in young adult survivors of childhood cancer

PURPOSE/OBJECTIVES

To explore the relationship between posttraumatic stress disorder (PTSD) and quality of life (QOL)/psychological outcome in young adult survivors of childhood cancer.

DESIGN

Cross-sectional, descriptive study.

SETTING

A large comprehensive pediatric cancer center on the West Coast.

SAMPLE

Fifty-one young adult survivors of childhood cancer, 18-37 years of age, disease free, and off treatment for an average of 11 years (range 2.8-26.7 years).

METHODS

A structured clinical interview was used to establish a PTSD diagnosis. Self-report instruments were used to assess QOL (RAND SF-36) and psychological distress (Brief Symptom Inventory (BSI)). Survivors with and without PTSD were compared on the BSI and RAND SF-36.

MAIN RESEARCH VARIABLES

PTSD status, QOL and psychological distress.

FINDINGS

Eleven subjects (20%) met full criteria for PTSD. Significant group differences were found for 17 of the 18 outcome variables. Survivors with PTSD reported clinically significant levels of psychological distress, whereas symptom levels for those without PTSD fell well within population norms. On all domains, QOL scores were significantly lower for the PTSD group compared to the non-PTSD group.

CONCLUSIONS

PTSD in survivors of childhood cancer is related to long-term outcome. PTSD is associated with a poorer QOL (physical and mental) and an increase in psychological distress. Data suggest that survivors with PTSD have significant functional limitations and psychological comorbidity.

IMPLICATIONS FOR NURSING PRACTICE

Screening cancer survivors for PTSD will identify high-risk patients who need further evaluation and intervention.

A pilot study of posttraumatic stress and nonadherence in pediatric liver transplant recipients

BACKGROUND

Symptoms of posttraumatic stress disorder (PTSD) were described in survivors of life-threatening diseases, the trauma being the experiences associated with the disease or its treatment. Their prevalence in liver transplant recipients is unknown. Based on clinical observations, we hypothesize that a significant proportion of pediatric liver transplant recipients suffers from PTSD symptoms. We further hypothesize that nonadherence (noncompliance) to medical management may, in some cases, be associated with these symptoms. Traumatized patients, according to this hypothesis, will avoid taking their medications, because these serve as painful reminders of the disease.

OBJECTIVES

To determine the prevalence of PTSD symptoms in a sample of pediatric liver transplant recipients. To determine whether symptoms of PTSD are associated with nonadherence in these patients. To describe the clinical presentation of PTSD and the management of severe nonadherence in patients who suffer from this disorder.

METHODS

Nineteen pediatric liver transplant recipients and their caretakers were interviewed, using the UCLA Post Traumatic Stress Disorder Reaction Index (PTSRI). Data were obtained on a few demographic parameters and perception of disease threat. Adherence was evaluated by 2 methods: 1) a clinician panel (taking into account the clinical sequelae of severe nonadherence); and 2) computation of the standard deviations (SDs) of consecutive determinations of blood levels of Tacrolimus (a higher SD means higher variability between individual measures and is therefore an indicator of nonadherence). As an illustration of the general phenomenon, we describe 3 cases of liver transplant recipients who were nonadherent and who suffered from PTSD.

RESULTS

Six of 19 patients had positive scores on all 3 components of the PTSRI (PTSD patients). Three of these, and none of the others, were considered significantly nonadherent by the panel. Therefore, nonadherence was significantly associated with the existence of symptoms from all 3 domains of PTSD (Fisher's exact test) in our sample. In particular, a high avoidance score on the PTSRI was highly correlated with panel-determined nonadherence. Further, SD of medication levels were significantly higher in PTSD patients, compared with the rest of our sample. No significant differences were found in perception of disease threat or demographic variables between PTSD patients and the rest of our sample. The 3 cases that we describe became adherent to their medications when symptoms of PTSD subsided during the course of therapy.

CONCLUSIONS

Clinically significant nonadherence, determined by 2 different methods, was associated with the full spectrum of PTSD symptoms in this sample. It was especially associated with a high avoidance score, which suggests that avoidance of reminders of the disease (eg, medications) may be a mechanism of nonadherence. Screening for and management of these symptoms, therefore, may improve adherence. This novel concept may be applicable to other patient populations. However, more data are needed before any definite conclusions can be drawn.

Posttraumatic stress disorder: understanding the psychosocial impact of surviving childhood cancer into young adulthood

Little research has been done to explore how the psychological symptoms of child and adolescent cancer survivors change in the decades following successful treatment. This article examines these changes with a focus on the utility of a posttraumatic stress framework for understanding the long-term coping issues that individuals face as they mature and make transitions to young adulthood. First, the literature supporting the use of a posttraumatic stress framework in child and adolescent survivors is reviewed. Developmental contributions to changes and increases in posttraumatic symptomatology during young adulthood are then discussed and posttraumatic symptoms most often seen in this group are presented. Preliminary research with young adult survivors is also reviewed and discussed as support for a posttraumatic stress framework with this population. Ongoing research efforts aimed at elaborating on this framework are described. Finally, clinical implications for health care providers are explored, and guidelines for assessing the impact of posttraumatic stress on young adults' use of health care resources are offered.

Predicting posttraumatic stress symptoms in mothers and fathers of survivors of childhood cancers

OBJECTIVE

To predict posttraumatic stress symptoms in parents of survivors of childhood cancer, using as predictors the following: personality (trait anxiety); current family and individual variables (perceived life threat, perceived treatment intensity, life events, family functioning, and social support); posttreatment variables (time since treatment ended, child anxiety, medical sequelae); and treatment events (age at diagnosis, radiation therapy, intensity of treatment).

METHOD

Mothers and fathers of 6- to 20-year-old survivors of childhood cancer (n = 331 families) completed a questionnaire battery in this two-site study. The outcome variable was the Posttraumatic Stress Disorder Reaction Index. Multiple regressions and path analyses were used to test the model.

RESULTS

For both mothers and fathers, anxiety was the strongest predictor of posttraumatic stress symptoms. The current family and individual variables also contributed significantly, particularly with respect to the individual contributions of perceived life threat, perceived treatment intensity, and social support. Objective medical data did not contribute to posttraumatic stress symptoms.

CONCLUSIONS

Parental anxiety warrants attention throughout the course of treatment for childhood cancer and after treatment ends. Beliefs about past and present life threats associated with cancer treatment and family and social support are other important targets for intervention.

Is posttraumatic stress a viable model for understanding responses to childhood cancer?

The application of a trauma model to understanding the impact of life-threatening illness has been informative. In the case of childhood cancer patients, it appears clear that a full PTSD syndrome is not the normative response either during or after treatment. Some aspects of cancer diagnosis and treatment, however, are experienced as traumatic by a subset of children, some of whom report symptoms of posttraumatic stress. There is some evidence that children may respond to cancer treatment as a repeated trauma, with the result of more subtle changes in affect modulation, world view, and interpersonal relationships. This area requires further investigation. The trauma model is also useful in understanding parental responses to childhood cancer. The epidemiologic data to date regarding posttraumatic stress symptoms in parents of childhood cancer survivors is consistent with the trauma literature regarding responses to moderate-magnitude traumatic exposure. These findings have important implications for clinical interventions for families of childhood cancer patients. More research is needed in the prediction and prevention of the long-term distress reported by so many parents of children who have undergone successful treatment for life-threatening illness.

Predictors of posttraumatic stress symptoms in childhood cancer survivors

OBJECTIVE

The diagnosis and treatment of childhood cancer are extremely stressful experiences, with psychological sequelae which can persist many years after the end of treatment. This study investigated the relative contributions of general anxiety, treatment intensity, medical sequelae of treatment, and the subjective appraisal of life threat and treatment intensity to later posttraumatic stress symptoms, such as intrusive memories, avoidance, and hypervigilance.

METHOD

One hundred eighty-six childhood cancer survivors ages 8 through 20 years, off of treatment for more than 1 year, and their parents completed questionnaires. Medical sequelae of treatment and intensity of treatment were rated by a pediatric oncologist.

RESULTS

Significant, independent predictors of persistent posttraumatic stress symptoms included: 1) the survivor's retrospective subjective appraisal of life threat at the time of treatment, and the degree to which the survivor experienced the treatment as "hard" or "scary"; 2) the child's general level of anxiety; 3) history of other stressful experiences; 4) time since the termination of treatment (negative association); 5) female gender; and 6) family and social support. Mother's perception of treatment and life threat contributed to anxiety and subjective appraisal for the survivor, but did not independently contribute to posttraumatic stress symptoms.

CONCLUSIONS

Symptoms of posttraumatic stress seem to decrease with time, but are persistent in a subset of childhood cancer survivors. Other than time and gender, the predictors of posttraumatic stress symptoms are primarily subjective factors (ie, anxiety and subjective appraisal) rather than objective stressors of treatment and medical sequelae.

Families surviving childhood cancer: a comparison of posttraumatic stress symptoms with families of healthy children

Compared posttraumatic stress symptoms in 309 8- to 20-year-old survivors of childhood cancer and their parents with healthy children and their parents who responded to child-related stressors. The relationship of child demographic, cancer and treatment, and family and social support factors with posttraumatic stress symptoms was analyzed also. Results indicate that mothers and fathers of childhood cancer survivors showed significantly higher levels of posttraumatic stress symptoms than comparison parents. The survivors themselves did not differ from their healthy counterparts. Past perceived life threat and family and social support resources contributed to posttraumatic stress symptoms in survivors and their parents. Survivor mother and child and survivor father and child symptoms were associated. Implications for the long-term functioning of families of survivors and suggestions for preventive interventions are discussed.
