The Pressure-Activation-Stress scale in relation to ADHD and cortisol

Coping strategies and symptoms of Adjustment Disorder among adults with Attention Deficit Hyperactivity Disorder (ADHD) during the Covid-19 pandemic

BACKGROUND

The current study examined whether coping strategies and symptoms of Adjustment Disorder in adults with ADHD differed from what was observed in the general adult population during the Covid-19 pandemic, and compared the extent to which coping strategies and symptom levels of Adjustment Disorder were related to ADHD.

METHOD

This cross-sectional study was based on survey data collected during the spring of 2021 from 231 adult ADHD patients in specialist care and 1148 volunteers without ADHD in Sweden. The survey included questions about sociodemographic and clinical characteristics, along with the Brief-COPE and Adjustment Disorder-New Module 8 questionnaires. Regression models adjusting for sociodemographic and clinical characteristics were used for between-group comparisons of coping strategies and symptoms of Adjustment Disorder.

RESULTS

There were some notable differences in the use of coping strategies between persons with and without ADHD; however, many of these differences were not observed in the adjusted models. The use of behavioral disengagement was more frequently observed among individuals with ADHD, whereas planning was more common among individuals without ADHD. Individuals with ADHD appeared to show higher symptom levels of Adjustment Disorder during the pandemic. Passive coping strategies, such as denial, self-blame, and behavioral disengagement, were associated with higher symptom levels of adjustment disorder in both individuals with and without ADHD.

CONCLUSION

In conclusion, the results highlight that persons with ADHD may need more support to adjust to large societal changes than the general public. Potential targets for intervention towards members of this group include reducing resignation and maladaptive coping strategies.

Attention-Deficit/Hyperactivity Disorder and Unhealthy Lifestyle in Adolescence: Unforeseen Role of Allostatic Overload and Psychological Well-Being

Unhealthy lifestyle behaviors (ULBs) are common in early adolescence and could be worsened by Attention-Deficit/Hyperactivity Disorder (ADHD), as well as by specific psychosocial factors, such as stress and unbalanced (i.e., too high or low scores of) psychological well-being (PWB) dimensions. This multi-center study aimed to evaluate how interactions between ADHD symptoms and psychosocial factors associated with ULBs (i.e., Allostatic Overload and multidimensional Psychological Well-Being), considered as moderators, could affect the adoption of ULBs during adolescence. A total of 440 fourteen-year-old adolescents were recruited from six upper secondary schools in Bologna and Rome (Italy) and completed self-report questionnaires on ULBs, ADHD, and psychosocial factors. Relations between ADHD symptomatology and specific ULBs (i.e., impaired sleep, problematic Internet use) were moderated by variables deemed as "negative" (i.e., Allostatic Overload) or "positive" (i.e., PWB dimensions of Self-Acceptance, Personal Growth, Positive Relations, Purpose in Life, Environmental Mastery): when the "negative" moderator is absent and the levels of the "positive" moderators are higher, ULBs decrease among students with lower ADHD symptomatology but increase among students with more severe ADHD. Based on ADHD severity, interventions should aim at promoting a state of euthymia, which consists in balanced PWB dimensions and reflects the optimal level of well-being to fulfill one's own potential and self-realization.

General lifestyle factors explain young athletes' mental health more than perceived coach autonomy support: a cross-sectional study on basketball players and gymnasts aged 10-22

Objectives

This study described differences in lifestyle factors (sleeping problems/fatigue, pressure/activation), perceived coach autonomy support and indicators of mental health (well-being and poor general mental health) across various age groups (children ≤12 years, youths 13-15 years, junior to senior ≥16 years) and sports (basketball and gymnastics). Second, the relationships between lifestyle factors and mental health indicators were explored, hypothesising that the relationships would be mediated by perceived coach autonomy support.

Methods

A cross-sectional study design was implemented by using an online survey which assessed lifestyle and environmental factors as well as mental health indicators. Participants were recruited through sports clubs in basketball and gymnastics. A total of 209 athletes (77 basketball players and 132 gymnasts) in the age range of 10-22 (median=13) years volunteered to complete the survey.

Results

Separate two-way analyses of variance showed significant main effects for age group on sleeping problems/fatigue, sleep quantity, pressure/activation, well-being and poor general mental health, with higher scores reported for older age groups of athletes. Path analysis displayed sleeping problems/fatigue and pressure/activation to significantly affect decreased well-being and poor general mental health; however, the relationships were not mediated by perceived coach autonomy support.

Conclusion

Lifestyle factors play a prominent role in mental health outcomes. Researchers studying athlete mental health should consider both general lifestyle and sports-related factors, considering developmental phases in the young athlete's sporting context and overall life.

Genetically engineered mouse models of FK506-binding protein 5

FK506 binding protein 51 (FKBP51) is a molecular chaperone that influences stress response. In addition to having an integral role in the regulation of steroid hormone receptors, including glucocorticoid receptor, FKBP51 has been linked with several biological processes including metabolism and neuronal health. Genetic and epigenetic alterations in the gene that encodes FKBP51, FKBP5, are associated with increased susceptibility to multiple neuropsychiatric disorders, which has fueled much of the research on this protein. Because of the complexity of these processes, animal models have been important in understanding the role of FKBP51. This review examines each of the current mouse models of FKBP5, which include whole animal knockout, conditional knockout, overexpression, and humanized mouse models. The generation of each model and observational details are discussed, including behavioral phenotypes, molecular changes, and electrophysiological alterations basally and following various challenges. While much has been learned through these models, there are still many aspects of FKBP51 biology that remain opaque and future studies are needed to help illuminate these current gaps in knowledge. Overall, FKBP5 continues to be an exciting potential target for stress-related disorders.

Learning a Healthy Rhythm: An Intervention to Increase Children's Resources for Stress Management

This article describes a pilot test of a community engaged, culturally relevant, arts-based intervention. The purpose was to increase children's personal protective buffering resources. Protective buffering resources help children cope with stressful stimuli, reduce activation of their systemic stress response, mitigate allostatic load, and promote optimal health. The "Learning a Healthy Rhythm" intervention included a stress management component and an ongoing Afro-Latino percussion program for 18 children ages 9-11. The stress management component included educational content about stress, self-assessment of stress symptoms, and stress management techniques. A mixed-method intervention evaluation design was used. Qualitative data, quantitative data, and biometrics including hair cortisol were collected. Six intervention parameters were evaluated: effectiveness, fidelity, feasibility, acceptability, necessity, and safety. Positive results were obtained for all parameters. Reduction in physiological and subjective measures of stress was evident. This stress management intervention was well-received and supported by participants.

ADHD Diagnostic Trends: Increased Recognition or Overdiagnosis?

The prevalence of Attention Deficit Hyperactivity Disorder (ADHD) has seen a consistent rise in recent years. These numbers spark a debate over the reason for the observed trends, with some concerned about over diagnosis and over prescription of stimulant medications, and others raising the issue of diagnostic disparities, particularly in underrepresented populations. In this paper we look at both sides, starting with the history of ADHD and its diagnostic criteria changes, from early concepts of alterations in attention and hyperactivity in the 19th and 20th century, to its introduction in the Diagnostical and Statistical Manual of Mental Disorders (DSM), and its evolution into how it is defined today. The general broadening of ADHD diagnostically over time plays a role in the increased prevalence over the years, but it is not the only reason. Increased awareness of physicians and the public is also believed to play a big role, particularly in underrepresented minorities and women. However, there continues to be disparities in detection of ADHD in these groups. There are significant consequences to a patient's social, interpersonal, and professional life when ADHD is left unrecognized and untreated. Thoughtful evaluation, accurate diagnosis, and adequate treatment can make a big difference.

The Role of Comorbid Symptoms in Perceived Stress and Sleep Problems in Adolescent ADHD

We examined perceived stress and sleep problems in adolescent ADHD and whether this varies as a function of ADHD presentation and sex. Further, we mapped structural associations between ADHD symptoms, comorbid symptoms, perceived stress, and sleep problems. Participants were 306 adolescents aged 13-19 years (66.8% females, 193 had an ADHD diagnosis, 113 were controls). Parents rated ADHD symptoms, all other constructs were self-rated. Adolescents with ADHD had elevated levels of perceived stress and sleep problems. Girls with ADHD reported the highest levels of perceived stress. Emotional symptoms mediated the effect of inattention whereas conduct problems mediated the effect of hyperactivity/impulsivity on stress and sleep. Perceived stress and sleep problems should be considered when mapping ADHD-related problems. Comorbid symptoms are potential intervention targets that may increase treatment response.

The impact of preschool child and maternal attention-deficit/hyperactivity disorder (ADHD) symptoms on mothers' perceived chronic stress and hair cortisol

Providing care for a child with attention-deficit/hyperactivity disorder (ADHD) is associated with parenting stress. Moreover, adults with elevated ADHD symptoms report increased perceived stress. Despite this, it has rarely been examined whether and how child and maternal ADHD symptoms may affect maternal perceived stress and the stress-sensitive hypothalamic–pituitary–adrenal axis. This study therefore investigated the possible impact of child and maternal ADHD symptoms on mothers' perceived chronic stress and hair cortisol concentration (HCC), while simultaneously considering the effects of child oppositional defiant/conduct disorder (ODD/CD) and maternal depressive symptomatology. In total, 124 mothers (35.96 ± 5.21 years) of preschool children were included. Maternal perceived stress, ADHD and depressive symptoms were assessed using self-report measures. Child ADHD symptoms were assessed using an interview and questionnaires completed by mothers and teachers. Additionally, mothers provided information about their children’s ODD/CD symptoms. Hair samples were taken from mothers to assess HCC. Child and maternal ADHD, child ODD/CD, and maternal depressive symptoms accounted for 50% of the variance in perceived chronic stress (F(4, 119) = 30.24; p < 0.01), with only maternal ADHD (β = 0.52, p < 0.01) and depressive symptoms (β = 0.49, p < 0.01) being uniquely significant. Maternal ADHD symptoms did not moderate the relationship between child ADHD symptoms and maternal perceived chronic stress (b = − 0.01; SE b = 0.17; t(5, 118) = − 0.05; p = 0.96). Mother’s age became the only significant predictor of maternal HCC (β = 0.29; p < 0.01). Based on these findings, practitioners are advised to be aware of and take into account possible maternal ADHD and depressive symptomatology and perceived chronic stress when treating children diagnosed with ADHD.

The role of stress coping strategies for life impairments in ADHD

Attention-deficit/hyperactivity disorder (ADHD) is commonly accompanied by functional impairments within personal, professional, and social context as well as further psychological distress. The role of perceived stress has been examined in this regard, although little is known about the influence of stress coping strategies. We examined the dynamics between ADHD symptomatology, stress coping strategies, and life impairments in a sample of 230 clinical and non-clinical adult individuals. ADHD was associated with low probability of choosing adaptive but high probability of implementing maladaptive stress coping strategies as well as with increased life impairments. Adaptive stress coping showed little effects beyond the associations between ADHD and life impairments, whereas some maladaptive coping strategies increased current life impairments over and above the effects of ADHD and further psychological distress. The present findings emphasize the need of professional support in adults with ADHD and the necessity to include stress coping strategies in respective treatment approaches aimed at reducing life impairments.

The stress-Wnt-signaling axis: a hypothesis for attention-deficit hyperactivity disorder and therapy approaches

Attention-deficit hyperactivity disorder (ADHD) is one of the most common psychiatric neurodevelopmental disorders in children and adolescents. Although ADHD has been studied for nearly a century, the cause and pathophysiology of ADHD is yet largely unknown. However, findings from previous studies have resulted in the formation of a new hypothesis: Apart from the well-known multifactorial etiology of ADHD, recent evidence suggests that the interaction between genetic and environmental factors and especially Wnt- and mTOR-signaling pathways might have an important role in the pathophysiology of ADHD. The Wnt-signaling pathway is known to orchestrate cellular proliferation, polarity, and differentiation, and the mTOR pathway is involved in several significant processes of neurodevelopment and synaptic plasticity. As a result, dysregulations of these pathways in a time-dependent manner could lead to neurodevelopmental delays, resulting in ADHD phenotype. This review presents further evidence supporting our hypothesis by combining results from studies on ADHD and Wnt- or mTOR-signaling and the influence of genetics, methylphenidate treatment, Omega-3 supplementation, and stress.

Unseen and Stressed? Gender Differences in Parent and Teacher Ratings of ADHD Symptoms and Associations With Perceived Stress in Children With ADHD

Objective: In this study, we investigate the differences between parent and teacher ADHD ratings, and how these ratings relate to perceived stress in children with ADHD. Method: Ratings by parents and teachers with the Swanson, Nolan and Pelham ADHD symptom rating scale (SNAP-IV) were collected from children with a clinical diagnosis of ADHD (n = 137). Also, information on medication was collected. Children (≥11 years of age; n = 64) were invited to complete the Pressure-Activation-Stress scale. Results: Among girls, but not boys, teacher ratings were significantly lower than parental ratings on all symptom scales. Lower teacher ratings on hyperactivity symptoms were associated with higher levels of perceived stress. Conclusion: The findings suggest a potential gender bias in ratings among teachers. Underrated, and hence underidentified, ADHD problems in the school setting seem to increase the perception of stress in the sense of pressure for both girls and boys.

How do adolescents with ADHD perceive and experience stress? An interview study

Background: Attention-deficit/hyperactivity disorder (ADHD) is linked to high levels of perceived stress in adult populations. Thus, it is not surprising that stress managing techniques are being included in treatment protocols for adults with ADHD. There is, however, a paucity of studies on perceived stress in adolescents with ADHD.Aims: This study aims to explore how adolescents with ADHD perceive and experience stress (and stressors) using a qualitative approach.Methods: Explorative interviews were conducted with 20 adolescents (Mean age: 16.30) diagnosed with ADHD in conjunction with group treatment therapy. Data were analysed using qualitative content analysis.Results: Stress and ADHD, as well as stress, anxiety and ill-health, were described as closely intertwined. The result is presented in four categories: stress is often present, triggers of stress, stress affects daily life, and stress can be handled and prevented. A relation was found between stress and feelings of helplessness, ill-health and anxiety. Stress was viewed as being out of proportion with reality and was driven by such factors as ADHD symptoms, school demands, unpredictable situations and relational problems. Several negative consequences of stress were reported, including postponing schoolwork and the tendency to give up. Some participants also reported performing better when stressed. Accepting help from others, practising acceptance, settling down and controlling oneself, and planning in advance were seen as helpful stress managing techniques.Conclusions: Stress should be considered among other problems related to ADHD. Psychoeducation about stress, stress managing techniques and coaching should be included in the treatment of adolescents with ADHD.

Psychosocial functioning and the cortisol awakening response: Meta-analysis, P-curve analysis, and evaluation of the evidential value in existing studies

Cortisol levels rise immediately after awakening and peak approximately 30-45min thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and meta-analysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw responses. Based on these effect sizes, cross-sectional studies assessing CAR would need a minimum sample size of 617-783 to detect true effects with 80% power. Depression was linked to higher AUCw and posttraumatic stress to lower AUCw, whereas inconclusive results were obtained for predictor-specific effects on CARi. Suggestions for future CAR research are discussed.

Perceived stress, recurrent pain, and aggregate salivary cortisol measures in mid-adolescent girls and boys

Measures of perceived stress have been criticized for theoretical inconsistency. However, the validated pressure activation stress scale has been suggested as a theoretically sound alternative. But it is unclear how pressure and activation stress relate to objective and subjective measures including commonly used aggregate cortisol measures and health complaints respectively. Specifically, this study aimed at investigating how pressure and activation stress were related to aggregate salivary cortisol measures and recurrent pain in mid-adolescent girls and boys. Mid-adolescents (119 girls and 56 boys) provided self-reports in questionnaires on activation and pressure stress and recurrent pain (headache, stomach ache, neck/shoulder and back pain). Additionally, adolescents sampled saliva during an ordinary school day: (1) immediately at awakening; (2) 30 minutes after waking up; (3) 60 minutes after waking up, and (4) at 8 p.m. These samples were analyzed for cortisol. Hierarchical regressions showed no statistically significant associations between activation and pressure stress and cortisol, neither for girls nor for boys. However, activation and pressure stress were significantly associated with recurrent pain but only for girls. The findings may relate to subjective and objective measures reflecting distinct aspects of stress-related functioning. However, the study participants included mid-adolescents whose bodily systems are flexible and still relatively unaffected by the strain of their daily stress perceptions. To conclude, the non-significant relationships between activation and pressure stress and commonly used aggregate measures of cortisol adds to the understanding of how perceived stress may relate to physiological functioning in the daily life of adolescents when using such aggregate measures.

Gender-specific differences in hypothalamus-pituitary-adrenal axis activity during childhood: a systematic review and meta-analysis

BACKGROUND

Gender-specific differences in hypothalamus-pituitary-adrenal (HPA) axis activity have been postulated to emerge during puberty. We conducted a systematic review and meta-analysis to test the hypothesis that gender-specific differences in HPA axis activity are already present in childhood.

METHODS

From inception to January 2016, PubMed and EMBASE.com were searched for studies that assessed non-stimulated cortisol in serum or saliva or cortisol in 24-h urine in healthy males and females aged ≤18 years. Studies that conform with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement were reported. Standardized mean differences (95% CIs) were calculated and analyzed using fixed-effect meta-analysis stratified for age: <8 years (prepubertal) and 8-18 years (peri-/postpubertal). For comparison, we ran the same analyses using random-effects models.

RESULTS

Two independent assessors selected 413 out of 6158 records (7%) for full-text screening, of which 79 articles were included. Of these, 58 (with data on 16,551 subjects) were included in the meta-analysis. Gender differences in cortisol metabolism differed per age group. Boys aged <8 years had 0.18 (0.06; 0.30) nmol/L higher serum and 0.21 (0.05; 0.37) nmol/L higher salivary cortisol levels, while between 8 and 18 years, boys had 0.34 (0.28; 0.40) nmol/L lower serum and 0.42 (0.38; 0.47) nmol/L lower salivary cortisol levels. In 24-h urine, cortisol was consistently higher in boys, being 0.34 (0.05; 0.64) and 0.32 (0.17; 0.47) μg/24 h higher in the <8- and 8-18-year groups, respectively. However, gender-differences in serum cortisol <8 years and between 8 and 18 years were absent when using random-effects models.

CONCLUSIONS

Gender differences in cortisol metabolism are already present in childhood, with higher salivary cortisol in boys aged <8 years compared to girls. This pattern was reversed after the age of 8 years. In contrast, the gender-specific difference in cortisol production as assessed through 24-h urine did not change with age. Although differences were small, and analyses of gender differences in serum cortisol were inconclusive, they might contribute to gender-specific origins of health and disease.

Polymorphisms in the FK506 binding protein 5 gene are associated with attention deficit hyperactivity disorder and diurnal cortisol levels

AIM

Previous studies have shown an association between childhood attention deficit hyperactivity disorder (ADHD) and a down-regulated hypothalamus-pituitary-adrenal axis (HPA axis) with low diurnal cortisol levels. Given the role of the FK506 binding protein 5 (FKBP5) as an important regulator of the negative feedback system of the HPA axis, we set out to investigate possible associations between single nucleotide polymorphisms (SNPs) in FKBP5 in relation to ADHD and diurnal cortisol levels.

METHODS

Children with ADHD (n = 81) and healthy comparisons (n = 88) collected saliva four times during a regular school day for radioimmunoassay analysis of cortisol and for genotyping of five SNPs in FKBP5 (rs9296158, rs1360780, rs9470080, rs7748266 and rs9394309).

RESULTS

We found associations between SNP genotypes and ADHD as well as between genotypes and diurnal cortisol levels. One of these SNPs, rs9470080, was significantly associated with both ADHD and lower cortisol levels.

CONCLUSION

This study contributes to previous findings on a down-regulated HPA axis in children with ADHD by demonstrating an association between ADHD, lower cortisol levels and SNPs of the FKBP5-gene. The relevance of these findings for the development and shaping of ADHD symptoms needs to be approached in larger samples, preferably also taking stress reactivity into consideration.
