Understanding Maternal Sensitivity: Early Adversity, Arginine Vasopressin 1a Receptor Gene and Gene-environment Interplay

Bisceglia, Rossana 29 August 2011 (has links)
The purpose of these studies was to examine mediation and moderation processes for the influence of early adversity and current stressful circumstances on maternal sensitivity. Evidence of mediation was found in Study 1 where maternal depression and mothers’ negative appraisal of their infant mediated the influence of early adversity and low family income on maternal sensitivity. Study 1 also examined the influence of the neighborhood. A moderate-mediation model was tested where the mediating influence afore-stated was hypothesized to vary across levels of neighborhood quality. Partial evidence of moderation was found. In the context of a high quality neighborhood, mothers’ early adversity was not associated with maternal depression. Across levels of neighborhood quality, complex relationships emerged between the variables low family income, maternal depression and mothers’ appraisal of infant temperament. In a context of low neighborhood quality, there was no evidence of a direct association between low family income and maternal sensitivity, rather, low family income operated indirectly through maternal depression. In a context of high neighborhood quality, there was evidence for a direct and indirect association between low family income and maternal sensitivity. Study 2 examined associations between variation in the Arginine Vasopressin 1a receptor gene (AVPR1a) and maternal sensitivity, and whether variation in this gene moderated the influence of mothers’ early adversity on sensitivity. Mothers homozygous for the long alleles of the RS3 microsatellite were significantly less sensitive than mothers heterozygous for the long alleles and those homozygous for the short alleles. Homozygosity for the RS3 long alleles moderated the influence of mothers’ early adversity on their sensitivity; the influence of early adversity on maternal sensitivity was most pronounced for mothers with the RS3 long/long genotype. These results suggest that variation in the AVPR1a gene may be important not only for human maternal behavior, but also for stress reactivity.

Capturing Resilience in Context: Development and Validation of a Situational Judgment Test of Resilience

Teng, Yuejia 03 November 2017 (has links)
The current study developed a 40-item situational judgment test (SJT) to measure resilience in context. Undergraduate samples were used in the study and situational stems of the SJT consisted of both daily stressors and major life crises; each response alternative was designed to reflect one of five resilience-related factors. A crowd-sourcing method was utilized to create scoring keys for the SJT. The Resilience SJT demonstrated good psychometric properties, and showed evidence of construct and criterion-related validity. The SJT scores moderately correlated with scores from two resilience Likert scales, a hardiness scale as well as a negative affect scale. Compared to the two Likert-type resilience scales, the SJT demonstrated less overlap with hardiness, positive affect, and negative affect. Moreover, the SJT showed incremental validity in predicting global adjustment, but not academic achievement or college satisfaction, above and beyond the two other resilience measures. Lastly, the study examined different modes of resilient behavior and captured individuals’ mode choice tendencies for resilient responses to adverse situations. The Resilience SJT appears to be a viable alternative to capture resilience. Implications and limitations were discussed.

Unaccompanied Children in the United States: Mental Health, Adversity and Employment as Markers of Immigrant Integration

Hasson III, Robert G. January 2019 (has links)
Thesis advisor: Thomas M. Crea / Unaccompanied children have arrived at the US border in increasing numbers since 2012, reaching a peak of 59,692 children apprehended at the US border in 2016. This dissertation includes three studies to better understand the characteristics of integration as experienced by unaccompanied children who arrive to the US. The first study examines rates of PTSD in a sample of unaccompanied children receiving post release services. This study also includes a confirmatory factor analysis to examine the theoretical structure of the Child PTSD Symptom Scale (CPSS). The second study examines factors associated with adversity experienced by unaccompanied children who are exiting a long term foster care program. The third study examines factors associated with employment outcomes for unaccompanied children exiting the Unaccompanied Refugee Minor (URM) federal foster care program. Together, the three studies comprise an exploratory dissertation that sheds light on the characteristics of two primary features of immigrant integration, namely mental health and employment. / Thesis (PhD) — Boston College, 2019. / Submitted to: Boston College.

Impact of Childhood Adversity on Executive Functioning and the Relationship Between Hypervigilance and Heuristics Among College Students

Van Newhouse, Tamara S 01 January 2023 (has links) (PDF)
The topic of exposure to childhood adversity has comprehensively been explored, and the effects of childhood trauma can undoubtedly impact a person on a lifelong continuum, still, investigation is unceasingly conducted. Much research has yet to be done when considering early adversity's outcomes on various stages throughout life and just how reoccurring consequences from early trauma may impair regulatory abilities and executive functioning beyond childhood. Research objective is to discover how early adversity influences later executive functions in conjunction to heuristics and the effects of hypervigilance in a college student populace. This study aims to examine the several variable differences from internal beliefs to external actions when considering the discrepancies between those with adversity to those without, and what factors may play a key role in harboring resilience through a quantitative experimental study. The importance of creating awareness for those impacted by early adversity is vital for building advocacy within society. The proposed study can potentially provide knowledge towards issues related to the influence of early adversity in Adulthood. Parallel to analyzing how early adversity impacts later life, examining student populations can provide findings that help depict in what ways the related factors influence trajectory both in academia and personal development and what role education may play.

Cool story, bro: : Storytelling towards external stakeholders

Nilsson, Isac, Nordgärd, Axel, Zetterberg, Martin January 2016 (has links)
Corporate storytelling is a recognized marketing strategy, however the usage of it is regarded to be unclear from a theoretical perspective. Further, the internal usage of storytelling among organizations is more common than the external use. Hence, this research was aimed towards storytelling for external stakeholders.

ADHD and stress : Diurnal cortisol levels, early psychosocial adversity and perceived stress

Isaksson, Johan January 2014 (has links)
The Hypothalamus-Pituitary-Adrenal axis (HPA-axis) with its end product cortisol mediates the physiological response to stress thereby promoting mobilization of energy. The cortisol levels follow a diurnal rhythm with a distinct awakening response. Regulation of the HPA-axis differs among persons with certain psychiatric disorders when compared with controls. Some reports concern Attention-Deficit/Hyperactivity Disorder (ADHD) but findings are inconclusive. The main aim of the present thesis was to investigate diurnal levels of saliva cortisol in school aged children with ADHD and age matched non-affected comparisons, also taking early adversity, perceived stress and ADHD-medication into consideration. Children with ADHD had lower cortisol levels at awakening, 30 minutes later and before going to bed than comparisons. When the study group was split into three different age groups similar results were found only for children above 10 years of age. Within the ADHD group, subtype of ADHD or co-occurring symptoms did not affect the cortisol levels. Furthermore, children in the ADHD group had to a higher degree been exposed to foetal and childhood psychosocial adversity than comparisons. Since exposure to early adversity has been associated with both ADHD and HPA-axis functioning, such exposures could theoretically explain the low cortisol levels in ADHD via early programming of the HPA-axis. However, no relation was found between exposures to psychosocial adversity and diurnal cortisol levels. Neither did continuous medication with stimulants or atomoxetine explain the low cortisol levels. Possibly, medication may rather increase the levels. Finally, children with ADHD scored higher on perceived stress, measured by the Pressure-Activation-Stress (PAS) scale, than the comparison group. Female sex was also associated with higher stress in both groups, as well as increasing age in the comparison group. As with psychosocial adversity, no association was found between the higher PAS-scores and the lower cortisol levels, indicating the complexity of the stress regulating system. The results indicate a down-regulated or displaced HPA-axis with lower cortisol levels in children with ADHD. Stress related fragility – with more exposure to early stressors, higher perceived stress and lower diurnal cortisol levels – seem to accompany ADHD during childhood.

När handeln flyttar från stadskärnan till annan arena : En kvalitativ studie om entreprenörernas sätt att attrahera kunder till city / When trading moves from city center to other arenas : A qualitative essay of entrepreneurs way to attract customers to the city

Persson, Malin January 2017 (has links)
Bakgrund:Handeln på externa handelsområden ökar stadigt och har ett fortsatt högt tryck, då ny handelsyta om 2 miljoner kvadratmeter planeras byggas i Sverige. Trots det väljer vissa företagare att ha kvar sina verksamheter i stadskärnorna. Syfte: Syftet är att skapa en djupare förståelse för vad entreprenörerna i Växjö city gör för att attrahera kunder tillbaka till stadskärnan efter att gallerian Grand Samarkand öppnat på en extern handelsplats i Växjö. Metod:  En kvalitativ metod med ett induktivt angreppssätt har använts där empirisk data insamlats genom att låta intervjupersonerna berätta sin berättelse inom det valda ämnet. Slutsats: Entreprenörerna väljer att inte bara stå still och låta motgångarna passera, vilket skulle vara ett steg i negativ riktning. De har flera idéer och tankar på hur de ska attrahera kunder till city. Genom att vara serviceminded och erbjuda kunderna webbhandel, egendesignade smycken, workshops, unika produkter och aktiviteter tillsammans med andra företagare och partners försöker de attrahera kunder till city för shopping. Vidare forskning: Ta reda på kundens aspekt av att handeln flyttar till andra arenor och vad som skulle kunna få dem till att shoppa mer i stadskärnan. / Background: Trading on areas outside town centers is steadily increasing and this area have remained high pressure, new retail space of 2 million square meters are planned to be built in Sweden. But some entrepreneurs choose to keep their businesses in city centers. Purpose: The aim is to create a deeper understanding of what entrepreneurs in Växjö city do to attract customers back to the city center after Grand Samarkand opened on an external trading place in Växjö. Methodology: A qualitative method with an inductive approach has been used where the empirical data was collected by allowing respondents to tell their story in the chosen topic. Conclusion: Entrepreneurs choose to not stand still and let the setbacks pass, which would be a step in a negative direction. They have several ideas and thoughts on how to attract customers to the city center. By being service minded and offering customers e-commerce, selfdesigned jewelry, workshops, unique products and activities with other business owners and partners they try to attract customers to the city for shopping. Further research: The customer aspect of the trade moving to other arenas and what might get them to shop in the city centers.

Distal risk factors, interpersonal functioning & family skills training in attempted suicide

Rajalin, Mia January 2017 (has links)
Background Suicidal behavior is an important global health problem affecting also significant others. Both genetic and environmental influences play an important role in the development of suicidal behavior. There is a need of interventions for family and friends after a suicide attempt. The aim of this thesis was to assess the impact of family history of suicide (FHS) and early life adversity (ELA) on severity of suicidal behavior and on level of interpersonal problems in suicide attempters. Furthermore it aimed to evaluate a DBT-based skills training program, Family Connections (FC), for relatives and friends of suicide attempters. Methods Studies I and II included 181 suicide attempters. FHS was assessed with the Karolinska Self-Harm History Interview or in patient records. ELA was assessed with the Karolinska Interpersonal Violence Scale (KIVS) measuring exposure to interpersonal violence in childhood. Suicide intent was measured with the Freeman scale. Interpersonal problems were assessed with the Inventory of Interpersonal Problems (IIP). Study III, a pilot study evaluating the effect of FC for family members of suicide attempters, included 13 participants who completed the program with pre- and post-questionnaires. The experience of burden was assessed with the Burden Assessment Scale (BAS), general wellbeing with Brief Symptom Inventory (BSI) and level of depression was assessed with Beck Depression Inventory (BDI). The Swedish scale Questions About Family Members (QAFM) was used to explore the quality of the participants’ relationship with the patient and the Quality of Life Inventory (QOLI) was used to measure satisfaction with life situation. Study IV included 132 family members, and investigated the feasibility and preliminary efficacy of FC in psychiatric care. Participants were assessed pre- and post-intervention with the following self-report questionnaires: BAS, QAFM and Five Facet Mindfulness Questionnaire. Results Male suicide attempters with FHS made more serious and well planned suicide attempts and had higher suicide risk. FHS and exposure to interpersonal violence as a child were independent predictors of suicide in male suicide attempters. Regarding interpersonal problems, suicide attempters with FHS had significantly more often an intrusive personal style, indicating that they might have an impaired ability to create stable, long-lasting relationships. In the pilot study the participants reported a significant reduction in burden, an improved psychic health and an improvement in the relationship with the patient after completing FC. In the fourth study, FC showed to be feasible and effectively implemented in a psychiatric outpatient services clinic. Regarding burden, results were in line with the pilot study, with a significant reduction in all subscales in BAS. Conclusions High-risk patients call for a consideration of both ELA and FHS in clinical suicide risk assessment. In suicide attempters at biological risk, suicide might be prevented with the early recognition of environmental risks. Further, the interpersonal problems associated with FHS may cause difficulties for suicide attempters to accept or benefit from treatment, and caregivers should take into account the characteristics of the suicide attempter´s interpersonal functioning. The results from the pilot study provide support for the need and importance of an educational program addressed specifically to family members of suicide attempters. Preliminary results support the feasibility and potential value of an implementation of FC in psychiatric open care clinics.
