Neural effects of controllability as a key dimension of stress exposure / Emily M. COHODES in Development and Psychopathology, 35-1 (February 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-1 (February 2023) . - p.218-227 Titre : Neural effects of controllability as a key dimension of stress exposure Type de document : Texte imprimé et/ou numérique Auteurs : Emily M.

GEE, Auteur Article en page(s) : p.218-227 Langues : Anglais (eng) Mots-clés : control  frontolimbic circuitry  stress reactivity  stress  stressor controllability Index. décimale : PER Périodiques Résumé : Cross-species evidence suggests that the ability to exert control over a stressor is a key dimension of stress exposure that may sensitize frontostriatal-amygdala circuitry to promote more adaptive responses to subsequent stressors. The present study examined neural correlates of stressor controllability in young adults. Participants (N = 56; M age = 23.74, range = 18-30 years) completed either the controllable or uncontrollable stress condition of the first of two novel stressor controllability tasks during functional magnetic resonance imaging (fMRI) acquisition. Participants in the uncontrollable stress condition were yoked to age- and sex-matched participants in the controllable stress condition. All participants were subsequently exposed to uncontrollable stress in the second task, which is the focus of fMRI analyses reported here. A whole-brain searchlight classification analysis revealed that patterns of activity in the right dorsal anterior insula (dAI) during subsequent exposure to uncontrollable stress could be used to classify participants' initial exposure to either controllable or uncontrollable stress with a peak of 73% accuracy. Previous experience of exerting control over a stressor may change the computations performed within the right dAI during subsequent stress exposure, shedding further light on the neural underpinnings of stressor controllability.

Stress and diurnal cortisol among Latino/a college students: A multi-risk model approach / Leah D. DOANE ; Jinni SU ; Kevin J. GRIMM in Development and Psychopathology, 36-2 (May 2024)  

Public ISBD [article]  inDevelopment and Psychopathology > 36-2 (May 2024) . - p.719-735 Titre : Stress and diurnal cortisol among Latino/a college students: A multi-risk model approach Type de document : Texte imprimé et/ou numérique Auteurs : Leah D. DOANE, Auteur ; Jinni SU, Auteur ; Kevin J. GRIMM, Auteur Article en page(s) : p.719-735 Langues : Anglais (eng) Mots-clés : HPA axis  Latino/a  college students  cortisol  stress Index. décimale : PER Périodiques Résumé : The transition to college is a time of increased opportunity and stress spanning multiple domains. Adolescents who encounter significant stress during this transition may be vulnerable to adverse outcomes due to a "wear and tear" of the hypothalamic pituitary adrenal (HPA) axis. Latino/a students may be particularly at-risk for heightened stress exposure due to experiences of both minority-specific and general life stress. Despite this, little is known regarding the cumulative impact of multiple stressors on Latino/a students' HPA axis functioning. The present study employed a "multi-risk model" approach to examine additive, common, and cumulative effects of multiple stress forms (general, academic, social, financial, bicultural, ethnic/racial discrimination) on diurnal cortisol in a sample of first-year Latino/a college students (N = 196; 64.4% female; Mage = 18.95). Results indicated that no stress forms were additively associated with the cortisol awakening response (CAR), but general stress was associated with a flatter diurnal cortisol slope (DCS) and bicultural stress was linked with a steeper DCS. A college stress latent factor was associated with a lower CAR, whereas a latent factor of discrimination was not associated with diurnal cortisol. Cumulative risk was linked with a lower CAR. Findings highlight the physiological correlates of various stressors experienced by Latino/a college students.

Stress and Family Quality of Life in Parents of Children with Autism Spectrum Disorder: Parent Gender and the Double ABCX Model / Rebecca L. MCSTAY in Journal of Autism and Developmental Disorders, 44-12 (December 2014)

What remains unclear is the impact of family-related variables on outcomes in both mothers and fathers within the same family. We explored the potential predictors of maternal and paternal stress and family quality of life in an Australian sample of 196 parents of children with ASD aged 3–16 years. Using a cross-sectional design, parents completed questionnaires assessing factors within the Double ABCX model attributed to family adaptation. Findings provide further evidence of the negative impact of child externalising behaviours and highlight the importance of family sense of coherence on positive parental outcomes.

Stress and Personal Resource as Predictors of the Adjustment of Parents to Autistic Children: A Multivariate Model / Ayelet SIMAN-TOV in Journal of Autism and Developmental Disorders, 41-7 (July 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-7 (July 2011) . - p.879-890 Titre : Stress and Personal Resource as Predictors of the Adjustment of Parents to Autistic Children: A Multivariate Model Type de document : Texte imprimé et/ou numérique Auteurs : Ayelet SIMAN-TOV, Auteur ; Shlomo KANIEL, Auteur Année de publication : 2011 Article en page(s) : p.879-890 Langues : Anglais (eng) Mots-clés : Stress  Adjustment  Resources  Autism  Parents  Coherence Index. décimale : PER Périodiques Résumé : The research validates a multivariate model that predicts parental adjustment to coping successfully with an autistic child. The model comprises four elements: parental stress, parental resources, parental adjustment and the child’s autism symptoms. 176 parents of children aged between 6 to 16 diagnosed with PDD answered several questionnaires measuring parental stress, personal resources (sense of coherence, locus of control, social support) adjustment (mental health and marriage quality) and the child’s autism symptoms. Path analysis showed that sense of coherence, internal locus of control, social support and quality of marriage increase the ability to cope with the stress of parenting an autistic child. Directions for further research are suggested.

Stress in mothers of children with autism: Trait mindfulness as a protective factor / Caitlin M. CONNER in Research in Autism Spectrum Disorders, 8-6 (June 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-6 (June 2014) . - p.617-624 Titre : Stress in mothers of children with autism: Trait mindfulness as a protective factor Type de document : Texte imprimé et/ou numérique Auteurs : Caitlin M. CONNER, Auteur ; Susan W. WHITE, Auteur Article en page(s) : p.617-624 Langues : Anglais (eng) Mots-clés : Autism  Mindfulness  Parenting  Stress Index. décimale : PER Périodiques Résumé : Mindfulness-based interventions may reduce parents’ stress and improve parent–child relationships. Given the chronic nature of autism spectrum disorder (ASD) and its influence on parents’ stress, interventions to promote mindfulness may be especially helpful for parents of children with ASD. Prior to undertaking intervention development, it is first necessary to establish the relationship between mindfulness and stress, as other factors like child behavioral difficulties may overshadow the mother's regulation strategies. In a sample of mothers of children with ASD (n = 67) and a comparison sample of mothers without ASD (n = 87), mindfulness was significantly associated with the level of maternal stress above and beyond child behavior problems (non-ASD: ? = ?.232; F(1, 64) = 15.749, p .000; ASD: ? = ?.206; F(1, 84) = 15.576, p .000). Results suggest that interventions to promote mindfulness may be helpful in reducing parenting stress among mothers of children with ASD, as well as mothers of typically developing children. Due to the chronic nature of ASD, such interventions may be particularly applicable.
