The effect of mother–infant skin-to-skin contact on infants’ developing social expectations for maternal behavior was investigated longitudinally over infants’ first 3 months. Infants with and without skin-to-skin contact engaged with their mothers in the Still Face Task at ages 1 week, 1 month, 2 months, and 3 months. Infants with skin-to-skin contact began responding to changes in their mothers’ behavior with their affect at 1 month; infants without skin-to-skin contact did so at 2 months. At 3 months, infants with skin-to-skin contact increased their non-distress vocalizations during the still face phase, suggesting social bidding to their mothers. Skin-to-skin contact accelerated infants’ social expectations for their mothers’ behavior and enhanced infants’ awareness of themselves as active agents in social interactions. 相似文献

Evidence suggests between 1% and 6% of women develop post-traumatic stress disorder (PTSD) after childbirth. 'Hotspots' are moments of extreme distress during traumatising events that are implicated in symptoms of PTSD. This cross-sectional internet survey of hotspots examined (1) the content of intrapartum hotspots and (2) whether particular events, cognitions or emotions during hotspots are related to PTSD. Women (N?=?675) who experienced a difficult or traumatic birth completed a questionnaire composed of a validated measure of PTSD, questions concerning the existence of hotspots, and a newly developed measure of emotions and cognitions during hotspots. The majority of women (67.4%) reported at least one hotspot during birth and 52.9% had re-experiencing symptoms of these hotspots. Women were more likely to have PTSD if hotspots involved fear and lack of control (odds ratio (OR) 1.30, 95% CI 1.17-1.43) or intrapartum dissociation (OR 1.12, 95% CI 1.05-1.19). Risk of PTSD was higher if hotspots concerned interpersonal difficulties (OR 4.34, 95% CI 2.15-8.77) or obstetric complications (OR 3.35, 95% CI 1.64-6.87) compared to complications with the baby. 相似文献

We investigated the adverse impact of résumé screening, taking into account the intersectionality of minority characteristics. A correspondence audit test showed hiring discrimination depended on the strength of applicants' ethnic identification. The odds for rejection were 4–6 times higher for résumés with ethnic minority identifiers (Arab names; Arab affiliations) when compared with ethnic majority identifiers (Dutch names; Dutch affiliations). Sex moderated the ethnicity effect but the particular effect (ethnic prominence; double jeopardy against women or men) depended on the type and degree of ethnic identification, lending support for a within‐category approach to study ethnic prejudice. The four‐fifths rule resulted in similar findings. Theoretical implications regarding the intersectional effects of minority characteristics and practical implications regarding ways to avert adverse impact during résumé screening are discussed. 相似文献

This study aimed to evaluate whether emotional health factors, including anxiety and depression, stress, and social support, are associated with earlier youth initiation of alcohol and illicit substances during middle school (from the sixth to the eighth grade). Data for this study were from the Developmental Pathways Project, a longitudinal study of 521 youth sampled from the Seattle Public Schools. Discrete time survival analyses were used to assess the effects of depression, anxiety, stress, and support on initiation of substance use, measured every 6 months at five time points between sixth and eighth grade. Youth who had initiated prior to sixth grade had significantly higher levels of depressive symptoms. In multivariate survival analyses controlling for child race/ethnicity, gender, and socioeconomic status, and accounting for conduct problems, youth who reported higher levels of separation anxiety/panic symptoms were at decreased risk for early alcohol initiation. Children with higher levels of perceived teacher support had a significantly lower risk of alcohol initiation during early follow-up periods. Recent stressful life events in Grade 6 were associated with significantly greater risk of initiating an illicit substance by Grade 8. The current findings highlight the role of stress in the initiation of illicit substance use and suggest that teacher support is associated with lower risk for very early alcohol use. Future research examining anxiety as a predictor of substance use should distinguish between subtypes of anxiety. 相似文献

Death is inevitable and yet in US culture the discussion of death is somewhat taboo. Marriage and Family therapists are trained in the implications of grief and loss for clients who lose loved ones and yet examination of the impact of therapist mortality on clients is lacking in the clinical literature. This article examines ways that private practice therapists can both protect their client’s confidentiality and mitigate the impact of therapist sudden death on their clients with planning and forethought. In addition, the factors influencing the lack of empirical research on this topic is discussed in the context of social mores on death and how therapists’ own denial of mortality may impact their ability to connect with clients through the pain of grief and loss. Recommendations are made for therapists to evaluate their own attitudes towards mortality and develop a plan for client care in the event of their death. 相似文献

Having a brother or sister with an autism spectrum disorder (ASD) can significantly impact the life of a typically developing sibling. These relationships are generally characterized by less frequent and nurturing interactions than are evident in sibling constellations with neurotypical children or children with other developmental disabilities. One way to address this issue is to teach typically developing siblings skills to participate in a brother or sister's treatment. Including siblings in behavioral interventions is documented to be beneficial to both children, and is associated with generalization of skills for the sibling with ASD. Here we review this body of literature, present case examples from clinical practice, and make treatment recommendations for utilizing sibling-mediated behavioral approaches. 相似文献
