Optimism and pessimism in children with cancer and healthy children: confirmatory factor analysis of the youth life orientation test and relations with health-related quality of life

Pain Trajectories in Pediatric Inflammatory Bowel Disease: Disease Severity, Optimism, and Pain Self-efficacy

OBJECTIVES

This study aimed to characterize pain intensity (average, worst) and disease severity in youth with inflammatory bowel disease in the 12-month postdiagnosis, and to examine the relation between pain and risk (disease severity) and resilience (optimism, pain self-efficacy) factors over time.

METHODS

Data collection ran from February 2019 to March 2022. Newly diagnosed youth aged 8 to 17 with IBD completed numerical rating scales for average and worst pain intensity, Youth Life Orientation Test for optimism, and Pain Self-Efficacy Scale for pain self-efficacy through REDCap; weighted Pediatric Crohn's Disease Activity Index and the Pediatric Ulcerative Colitis Activity Index were used as indicators of disease severity. Descriptive statistics characterized pain and disease severity. Multilevel modeling explored relations between variables over time, including moderation effects of optimism and pain self-efficacy.

RESULTS

At baseline, 83 youth ( Mage =13.9, SD=2.6; 60.2% Crohn's disease; 39.8% female) were included. Attrition rates at 4 and 12 months were 6.0% and 9.6%, respectively. Across time, at least 52% of participants reported pain. Participants in disease remission increased from 4% to 70% over 12 months. Higher disease severity predicted higher worst pain, regardless of the time since diagnosis. Higher pain self-efficacy (1) predicted lower average and worst pain, especially at later time points and (2) attenuated the association between disease severity and worst pain when included as a moderator. Higher optimism predicted lower worst pain.

DISCUSSION

Pain is prevalent in pediatric inflammatory bowel disease and impacted by disease severity, pain self-efficacy, and optimism. Findings highlight modifiable intervention targets.

Optimism, pessimism, and physical health among youth: a scoping review

OBJECTIVE

High levels of optimism (and low levels of pessimism) are associated with improved physical health in adults. However, relatively less is known about these relations in youth. The present study aimed to review the literature investigating optimism, pessimism, and physical health in children and adolescents from populations with and without health conditions.

METHODS

We conducted a scoping review up until February 2024. Studies were included if they sampled youth (average age ≤18 years) and treated optimism or pessimism as predictors of health behaviors or outcomes. Data on study and sample characteristics, health outcome, optimism construct, and findings were extracted from eligible papers and results were synthesized.

RESULTS

Sixty studies were retained. Most studies were conducted in North America, with adolescents, and used cross-sectional designs and self-reported measures of health. Measures of optimism and pessimism differed across studies. Roughly one-third of studies sampled medical populations. Health categories included substance use, diet and physical activity, sexual health practices, medical adherence, other health behaviors, cardiometabolic health, subjective health/health-related quality of life, pain, sleep, and oral health. Generally, we observed adaptive associations between optimism and health. Higher optimism and lower pessimism were most consistently associated with lower rates of substance use and lower cardiometabolic risk.

CONCLUSIONS

The presence of optimism or the absence of pessimism appears to be associated with various adaptive health outcomes among youth with and without health conditions. Developmental, methodological, and clinical considerations for future research are discussed, such as conducting longitudinal studies with objective measures of health and psychometrically validated instruments.

Evaluation of Patient-Reported Outcome Measures of Positive Psychosocial Constructs in Children and Adolescent/Young Adults with Cancer: A Systematic Review of Measurement Properties

Introduction: Children, adolescents, and young adults with cancer are a vulnerable population in whom improvements in psycho-oncology care would be valuable. We previously published a scoping review exploring what is known about positive psychological constructs in this population. A key finding was that evidence-based patient-reported outcome measures (PROMs) were needed to standardize psycho-oncology research. Methods: We undertook a systematic review of measurement properties focused on PROMs in the pediatric and adolescent/young adults (AYAs) with cancer populations. We searched for PROMs that measured at least 1 of 15 previously identified, key positive constructs. This systematic review followed COSMIN guidelines, considered the gold standard manual for systematic reviews of measurement properties. Results: We identified 20 (22 if proxy reports are counted separately) unique PROMs that met inclusion criteria. Of those, only five were recommended for use given the current evidence. The remainder may be used if no alternative exists. Only eight PROMs had any evidence of content validity, considered the most important psychometric property by COSMIN. Many studies were at risk of bias owing to incomplete or suboptimal methods. Discussion: Five PROMs are considered reliable for the pediatric and AYA with cancer populations. A number of PROMs require additional research to ensure their items and instructions are comprehensive, relevant, and comprehensible to children and AYAs. Given the overall lack of research, this review may be considered a starting point for the future refinement of a core set of PROMs to measure positive psychological constructs.

Health-related quality of life in youth with abdominal pain: An examination of optimism and pain self-efficacy

OBJECTIVES

Abdominal pain adversely impacts children with functional gastrointestinal disorders (FGIDs) or organic gastrointestinal disorders (OGIDs); findings are inconsistent regarding diagnosis and health-related quality of life (HRQoL). This study utilizes a positive psychology framework to understand the experience of youth with abdominal pain (i.e., do positive psychological factors, such as optimism and pain self-efficacy, relate to higher HRQoL?). Consistent with a protective factor model of resilience, in which personal assets may serve as buffers between risk factors and negative outcomes, optimism and pain self-efficacy were examined as they relate to HRQoL in youth with abdominal pain. Specifically, exploratory moderational analyses examined a) if optimism and pain self-efficacy moderate the relation between pain and HRQoL, and b) whether diagnostic status moderated the relation between optimism/pain self-efficacy and HRQoL.

METHODS

In a cross-sectional, observational study, youth (n = 98; M_age = 13, SD = 3) experiencing abdominal pain related to FGIDs or OGIDs and one of their parents participated. Measures included pain intensity, optimism, pain self-efficacy, and HRQoL. Analyses controlled for diagnosis, age, and gender.

RESULTS

Higher pain and age related to lower HRQoL. Higher levels of optimism and pain self-efficacy associated with HRQoL beyond demographics. Optimism and pain self-efficacy did not moderate the relation between pain and HRQoL. Diagnostic status did not moderate the relation between optimism or pain self-efficacy and HRQoL.

DISCUSSION

Our results suggest positive relations between positive psychological factors (optimism, pain self-efficacy) and HRQoL in youth with abdominal pain. Such factors could be further examined in intervention studies.

Otimismo e ganho percebido em cuidadores de crianças com câncer

Com o objetivo de analisar as relações entre otimismo e ganho percebido em cuidadores de crianças com câncer, constituiu-se uma amostra de conveniência de 60 cuidadores, com média de idade de 36,5 anos (DP=9,17), 81,7% de mulheres, em um hospital de referência. Utilizaram-se os instrumentos: Teste de Orientação da Vida, Inventário de Desenvolvimento Pós-Traumático, e questionário sociodemográfico e clínico. Após análise estatística descritiva e inferencial, verificou-se correlação positiva entre otimismo e ganho percebido (percepção de recursos e competências pessoais). Otimismo e ganho percebido também se associaram às variáveis clínicas e sociodemográficas: cuidadores casados e com crianças fora de quimioterapia referiram maior ganho percebido; e cuidadores cujos filhos tinham mais tempo de tratamento, se mostraram mais otimistas e com maior ganho percebido. Conclui-se que características individuais e clínicas devem ser consideradas em intervenções com foco na ressignificação da experiência de ter um filho com câncer e o crescimento frente à adversidade.

Identification of Evidence for Key Positive Psychological Constructs in Pediatric and Adolescent/Young Adult Patients with Cancer: A Scoping Review

Introduction: Children and adolescents/young adults (AYAs) with cancer are a vulnerable population susceptible to numerous late effects, such as fatigue and depression, which may diminish their long-term psychological, physical, spiritual, and emotional health. A well-rounded understanding of how positive psychological constructs affect the quality of care and treatment outcomes is therefore warranted. Methods: We conducted a scoping review of 15 positive psychological constructs in children and AYAs with cancer. The primary research questions were (1) what is known about positive psychological constructs in children and AYAs with cancer; (2) what value is ascribed to these constructs by patients? Results: Two hundred seventy-six articles were included after database search and screening. These studies were mostly observational or qualitative and conducted in North America. Constructs were often poorly defined, and measurement tools used to gather data were wide ranging. Numerous factors were correlated with increased or decreased expression of certain constructs, but overall themes were difficult to identify. Similarly, patients often spoke of what increased or decreased expression of a construct, with less emphasis on what they implicitly value. Discussion: This scoping review found ample evidence for what increases or decreases expression of positive psychological constructs, but this evidence was observational and often conflicting. In the future, we recommend the development of a core set of psychological outcomes, with definitions and corresponding measurement tools. We further recommend an emphasis on randomized trials to more rigorously study how expression of constructs can be improved and what effect this has on the quality of life.

Profiles and predictors of resilient functioning in youths with pediatric cancer history

OBJECTIVE

To identify and predict resilient functioning over time among youths with pediatric cancer experience (YPCE).

DESIGN

YPCE aged 8-17 years (N = 231) were followed prospectively for 3 years. Their psychosocial adjustment was assessed using self-report and parent-report at 1 year (T2) and 3 years (T3) post-baseline.

METHODS

Latent profile analysis identified subgroups of YPCE with different patterns of adjustment over time. Self-reported factors from baseline and T2 were examined as predictors of subgroup membership.

FINDINGS

Three subgroups of youths were found. Two exhibited average (52.5% of the sample) to better-than-average (41.3%) functioning. One subgroup (6.2%) exhibited subclinical but at-risk range of adjustment. Low optimism and low connectedness to parents and school predicted membership in this group.

CONCLUSIONS

Most YPCE exhibit resilient functioning across time. However, approximately 6% report persistent maladjustment.

IMPLICATIONS

Most YPCE are well-adjusted, but those with low optimism and poor connection to parents or school may require monitoring for psychosocial difficulties.

Profiles of Adjustment in Pediatric Cancer Survivors and Their Prediction by Earlier Psychosocial Factors

Objective

To examine individual differences in pediatric cancer survivors' psychosocial adjustment and test the psychosocial predictors, assessed 2-3 years earlier, of those differences.

Method

Pediatric cancer survivors (n = 209, aged 8-17 years at baseline) and their parents were followed for 4 years. They provided reports of survivors' psychosocial adjustment at 3 years post-baseline, and latent profile analysis (LPA) was used to identify subgroups of survivors who differed on those reports. Multinomial logistic regression was used to predict group membership from self- and parent-reported psychosocial factors at baseline (child adjustment, disposition, and parental functioning) and at 1 year post-baseline (child social relations).

Results

The LPA revealed a 3-class model as the best fit: a "Resilient" group (65%), characterized by good psychosocial adjustment; a "Self-Reported At-Risk" group (23%), characterized by subclinical elevations in self-reported internalizing and attention problems; and a "Parent-Reported At-Risk" group (12%), characterized by subclinical elevations in parent-reported internalizing, externalizing, and attention problems and in self-reported attention problems. Several psychosocial predictors, including child posttraumatic stress, affectivity, and connectedness to school, as well as parental distress and overprotection, differentiated the Resilient group from the other groups, in expected directions.

Conclusions

The majority of pediatric cancer survivors exhibit enduring resilience. The protective factors identified for them-including positive affectivity and strong connectedness to school-may inform targeted prevention strategies for the minority of survivors who are at risk for maladjustment.

The Effect of Optimism and Connectedness on Psychological Adjustment of Children with Cancer and Comparison Peers

OBJECTIVE

The present study aimed to examine the relationship of optimism and connectedness with psychological adjustment outcomes in children with cancer and determine whether these relations differ for children with cancer and comparison peers.

METHODS

Participants were 155 children with cancer and 143 comparison youth without a history of cancer, aged 8 to 17 years at study entry, who were followed longitudinally over a 3-year period. Participants completed self-report measures at 3 time points: baseline optimism at study entry (T1), connectedness at 1 year after baseline (T2), and emotional symptoms at 3 years after baseline (T3). A series of regression analyses were conducted using conditional process analysis to examine whether connectedness mediated the relationship between optimism and psychological adjustment and whether this was moderated by health status (i.e., history of childhood cancer vs no history of cancer or other serious or chronic illness).

RESULTS

Connectedness to parents, peers, and friends significantly mediated the relationship between optimism and psychological adjustment (b parents = -0.1387, 95% confidence interval [CI] [-0.2341 to -0.0515]; b peers = -0.2021, 95% CI [-0.3575 to -0.0818]; b friends = -0.0703, 95% CI [-0.1640 to -0.0050]). However, this mediation was not significantly moderated by having a history of cancer. Cancer history did moderate the direct relationship between optimism and psychological adjustment and between connectedness to parents and psychological adjustment.

CONCLUSION

Findings suggest that patients with cancer are doing remarkably well with regard to adjustment. Connectedness with parents and peers mediates the relationship between optimism and psychological adjustment. As such, children with cancer who are identified as experiencing poor adjustment may benefit from interventions to foster connectedness.

Optimism as a Candidate Health Asset: Exploring Its Links With Adolescent Quality of Life in Sweden

This study aims to understand the role that optimism could play in the context of a health asset approach to promote adolescent health-related quality of life (HRQOL). Adolescents (n = 948), between 11 and 16 years old from a medium-sized rural town in Sweden, answered questionnaires measuring optimism, pessimism, and HRQOL. The findings indicate a significant decrease in optimism and a significant increase in pessimism between early and midadolescence. The study has allowed us to present associational evidence of the links between optimism and HRQOL. This infers the potential of an optimistic orientation about the future to function as a health asset during adolescence and by implication may provide additional intervention tool in the planning of health promotion strategies.

Psychosocial Late Effects in Pediatric Cancer Survivors: A Report From the Children's Oncology Group

BACKGROUND

This review was conducted to update the Children's Oncology Group (COG) Long-Term Follow-Up Guidelines (COG-LTFU Guidelines, version 4.0) regarding screening for psychosocial late effects of pediatric cancer.

PROCEDURE

Articles published between August 2009 and January 2011 that addressed psychosocial late effects of long-term survivors of pediatric cancer (n = 35) were reviewed by a multidisciplinary team of COG late effect experts.

RESULTS

The majority of studies in this time period indicate that survivors experience few psychosocial problems in long-term survivorship. A critical subset, however, is at increased risk for psychosocial late effects secondary to the treatment. Highlighted findings from this review include increased rates of suicidal ideation (SI), and health beliefs as robust predictors of SI, anxiety, and global distress. Survivors' health beliefs were associated with their perceptions of physical limitations, overall late effects, and cancer-related pain. While many survivorship studies continue to specify risk factors for anxiety and posttraumatic stress symptoms/posttraumatic stress disorder, others outcomes (e.g., developmental, interpersonal, and familial factors) appear to be emerging in importance.

CONCLUSIONS

Although the majority of childhood cancer survivors do not experience psychosocial problems, a subset will. The recent research findings have been included in the new COG-LTFU Guidelines that will assist in the targeted assessment and the treatment of survivors' psychosocial health.

Profiles of Dispositional Expectancies and Affectivity Predict Later Psychosocial Functioning in Children and Adolescents With Cancer

OBJECTIVE

Examined how individual differences in disposition among pediatric cancer patients predict their later psychosocial functioning.

METHODS

Patients aged 8-17 years (N = 223) reported on their disposition at baseline. One and three years later, self-reports and parent reports of patient psychosocial functioning were obtained. Latent profile analysis was used to identify subgroups that differed on baseline disposition and to compare them on later outcomes.

ESULTS

Three groups were identified: The "Positive" group (59%) had high optimism and positive affectivity and low pessimism and negative affectivity; the "Moderate" group (39%) had a similar profile, with less exaggerated scores; a small, "Negative" group (2%) had the opposite profile (low optimism/positive affectivity; high pessimism/negative affectivity). These groups differed in psychosocial functioning at follow-up, generally in expected directions.

CONCLUSIONS

Most patients have a disposition that may be protective. A small minority at high risk for maladjustment is distinguished by their disposition.

The effects of the Make a Wish intervention on psychiatric symptoms and health-related quality of life of children with cancer: a randomised controlled trial

OBJECTIVE

Children with life-threatening medical conditions frequently undergo invasive medical procedures that may elicit anxiety and distress. However, there are few empirically validated interventions that reduce mental health symptoms and increase the resilience of children during the acute stages of illness. This study aimed to evaluate the efficacy of the Make a Wish intervention for children with life-threatening cancer.

METHODS

The design was a wait-list-controlled trial with two parallel groups. Sixty-six children aged 5-12 with an initial diagnosis of life-threatening cancer were identified and randomly assigned to the Make a Wish intervention (n = 32) or a wait-list control group (n = 34). Children completed measures of psychiatric and health-related symptoms, positive and negative affect, hope, and optimism pre-intervention and post-intervention. After baseline data collection, children were interviewed and made an authentic wish that they wanted to come true. These wishes were made possible 5-6 months after baseline data collection, to fuel anticipation and excitement over the wish-fulfillment event. The post-intervention assessment point was 5 weeks after wish fulfillment (approximately 7 months after baseline data collection).

RESULTS

Children in the intervention group exhibited a significant reduction in general distress (d = 0.54), depression (d = 0.70), and anxiety symptoms (d = 0.41), improved health-related quality of life (d = 0.59), hope (d = 0.71), and positive affect (d = 0.80) compared to decrease in positive affect and no significant changes in the other measures in the control group.

CONCLUSIONS

These findings emphasize the role of hope and positive emotions in fostering the well-being of children who suffer from serious illnesses.

Risk and Resilience in Pediatric Chronic Pain: Exploring the Protective Role of Optimism

OBJECTIVE

Fear of pain and pain catastrophizing are prominent risk factors for pediatric chronic pain-related maladjustment. Although resilience has largely been ignored in the pediatric pain literature, prior research suggests that optimism might benefit youth and can be learned. We applied an adult chronic pain risk-resilience model to examine the interplay of risk factors and optimism on functioning outcomes in youth with chronic pain.

METHOD

Participants included 58 children and adolescents (8-17 years) attending a chronic pain clinic and their parents. Participants completed measures of fear of pain, pain catastrophizing, optimism, disability, and quality of life.

RESULTS

Consistent with the literature, pain intensity, fear of pain, and catastrophizing predicted functioning. Optimism was a unique predictor of quality of life, and optimism contributed to better functioning by minimizing pain-related fear and catastrophizing.

CONCLUSIONS

Optimism might be protective and offset the negative influence of fear of pain and catastrophizing on pain-related functioning.

The psychosocial experience of adolescents with haematological malignancies in Jordan: an interpretive phenomenological analysis study

The qualitative research method of interpretive phenomenological analysis was used to explore the lived experience of 14 Jordanian adolescents with haematological malignancies. They were admitted to two hospitals in Jordan and were interviewed for this study twice during the first six months after receiving their diagnosis. The results of this study revealed three themes: (1) Being in hospital, (2) The changing self, and (3) Fearing the unknown. When the participants were hospitalised due to their illness they were removed from their families and friends and prevented from engaging in their normal daily routine. Participants also reported receiving limited emotional and psychological support from health team members during hospitalisation. From the onset of cancer treatments, the bio-psychosocial side effects of the chemotherapy became one of the most distressing factors for participants affecting all aspects of their life and generated uncertainty about their future. The findings add to existing understanding of the lived experiences of cancer patients and in particular Jordanian adolescents. They provide a valuable insight for clinicians into improvements in service delivery to this group of patients.

Considering quality of life for children with cancer: a systematic review of patient-reported outcome measures and the development of a conceptual model

OBJECTIVES

An appraisal of pediatric cancer-specific quality-of-life (QOL) instruments revealed a lack of clarity about what constitutes QOL in this population. This study addresses this concern by identifying the concepts that underpin the construct of QOL as determined by a content analysis of all patient-reported outcome (PRO) instruments used in childhood cancer research.

METHODS

A systematic review was performed of key databases (i.e., MEDLINE, CINAHL, PsychINFO) to identify studies of QOL in children with cancer. A content analysis process was used to code and categorize all items from generic and cancer-specified PRO instruments. Our objective was to provide clarification regarding the conceptual underpinnings of these instruments, as well as to help inform the development of theory and contribute to building a conceptual framework of QOL for children with cancer.

RESULTS

A total of 6,013 English language articles were screened, identifying 148 studies. Ten generic and ten cancer-specific PRO instruments provided 957 items. Content analysis led to the identification of four major domains of QOL (physical, psychological, social, and general health), with 11 subdomains covering 98 different concepts. While all instruments reflected items relating to the broader domains of QOL, there was substantial heterogeneity in terms of the content and variability in the distribution of items.

CONCLUSIONS

This systematic review and the proposed model represent a useful starting point in the critical appraisal of the conceptual underpinnings of PRO instruments used in pediatric oncology and contribute to the need to place such tools under a critical, yet reflective and analytical lens.

Self-reported psychosocial wellbeing of adolescent childhood cancer survivors

PURPOSE

To describe self-reported psychosocial wellbeing of adolescent childhood cancer survivors (CCS) compared with a control group of their peers.

METHODS

In this case-control study, 170 CCS aged 12-18 years completed an internet survey. The survey was a modified version of the Youth'07 Health and Wellbeing Survey of Secondary School Students in New Zealand. The control group (historical comparison) were the 9107 Youth'07 survey participants. Psychosocial wellbeing was assessed by measures of a) wellbeing (WHO-5), b) anxiety (MASC-10), c) depression (RADS2-SF) and d) emotional and behavioural difficulties (SDQ).

RESULTS

The majority of CCS scored within the normal range across all four measures: wellbeing (89%), anxiety (93%), depression (94%) and emotional and behavioural difficulties (82%), leaving a small but important minority of CCS reporting significant clinical issues. Compared to their peers, adolescent CCS were no more likely to have an abnormal score for any of the psychosocial measures, and less likely to report abnormal psychosocial wellbeing (OR = 0.44, p = 0.0003) and prosocial behaviour problems (OR = 0.53, p = 0.009). Survivors of central nervous system tumours, older age, older age at diagnosis, and lower socioeconomic status were associated with some psychosocial difficulty.

CONCLUSIONS

Following a diagnosis of childhood cancer, intensive therapy, and the subsequent risk of adverse health outcomes, one might expect CCS to be doing less well than their peers in terms of psychosocial wellbeing. The findings of this study, however, show that CCS are doing as well, and in some respects better, than their peers.

Developing a conceptual model of teenage and young adult experiences of cancer through meta-synthesis

OBJECTIVES

To systematically identify and analyse published research exploring teenage and young adult experience of cancer to inform the development of a patient-reported outcome survey intended to explore if a correlation exists between specialist cancer care and quality of life for young people with cancer.

DESIGN

Systematic review and meta-synthesis.

DATA SOURCES

Medline, CINAHL Plus and PsycInfo were searched for literature published between 1987 and 2011.

REVIEW METHODS

Search terms included those for: population (e.g. teen, young adult); intervention (e.g. cancer); outcome (e.g. experience); and study type (e.g. qualitative).

INCLUSION CRITERIA

adolescents and young adults were both represented; diagnosis of cancer; published in English; and used qualitative methods to report an aspect of the cancer experience. Studies were excluded if they were reporting: palliative care experience; secondary data; or proxy views, i.e. parent or health professional perspective. Methodological quality was assessed using Cesario criteria and meta-synthesis involved deconstruction and decontextualising findings to identify common themes.

RESULTS

Three hundred and fifteen studies were identified, 17 fulfilled the inclusion criteria. Of these, most (59%), were assessed as being high quality, none were rated poor. Nine common themes were identified: psychosocial function, importance of peers, experience of healthcare, importance of support, impact of symptoms, striving for normality, impact of diagnosis, positive experiences, and financial consequences.

CONCLUSIONS

The conceptual model developed from the meta-synthesis depicts the mediators and consequences of cancer care that impact on young people's quality of life after a cancer diagnosis. The model highlights areas that require further exploration.

Cortisol-a Key Factor to the Understanding of the Adjustment to Childhood Cancer

BACKGROUND

Malignancy and its treatments could cause disturbance in homeostasisof body such as cortisol secretion. The present study has investigated the effects of cortisol level imbalance in behavioral and emotional adjustments.

METHODS

Seventy-eight children with Acute Lymphoblastic Leukemia (ALL) have involved in this study. Their salivary cortisol level, which were sensitive to pain and disruptive behaviors, have measured.

RESULTS

CORTISOL LEVEL EFFECT IN DIFFERENT PERIODS: within duration of reaction to pain, sensitivity to pain and disruptive behaviors have evaluated. In addition abnormal regulation of cortisol levels have shown a very strong relationship between sensitivity to pain and the disruptive behaviors. Cortisol suppression was responsible for adjustment by the participants to stressful conditions.

CONCLUSION

Previous investigations have shown that there is a low reaction to stressor which decreases the vitality as well as impairing a negative memory in low cortisol levels. The findings of the present study demonstrated a nonlinear relation between cortisol level and sensitivity to pain as well as disruptive behaviors. Therefore, regulation of cortisol- up and down- is predisposed to maladjustment.
