This study assessed secondborn adolescents' perceptions of changes in the allocation of family resources following their firstborn siblings' departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns' academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase in multiple types of resources in the year following their older sibling's departure. Consistent with resource dilution theory, perceptions of increases in fathers' companionship, fathers' attention, and mothers' companionship were related to improvements over time in secondborns' academic functioning.  相似文献

Hagopian, Rooker, and Zarcone (2015) evaluated a model for subtyping automatically reinforced self‐injurious behavior (SIB) based on its sensitivity to changes in functional analysis conditions and the presence of self‐restraint. The current study tested the generality of the model by applying it to all datasets of automatically reinforced SIB published from 1982 to 2015. We identified 49 datasets that included sufficient data to permit subtyping. Similar to the original study, Subtype‐1 SIB was generally amenable to treatment using reinforcement alone, whereas Subtype‐2 SIB was not. Conclusions could not be drawn about Subtype‐3 SIB due to the small number of datasets. Nevertheless, the findings support the generality of the model and suggest that sensitivity of SIB to disruption by alternative reinforcement is an important dimension of automatically reinforced SIB. Findings also suggest that automatically reinforced SIB should no longer be considered a single category and that additional research is needed to better understand and treat Subtype‐2 SIB.  相似文献

This paper explores some of the ways in which sexuality can intrude into the psychotherapeutic relationship and present both opportunities and risks to our work with adolescents. It highlights some of the complexities of this area of the clinical encounter, exploring the particular difficulties encountered by both patient and therapist when sexuality emerges in the transference and countertransference. While we are well aware of the centrality of sexual development during adolescence, far less has been written about the way in which sexuality and the erotic transference emerges and impacts on both patient and therapist. Given the profoundly unsettling nature of this area of work and its capacity to disrupt our thinking and psychic equilibrium, it is easy to underestimate how much we are drawn to avoid, negate and defend ourselves against registering such experiences. Through the discussion of clinical material with two adolescent patients, this paper explores some of these dynamics, addressing some of the technical dilemmas that frequently challenge us in this area of work. These include questions about whether and when it is therapeutically important and effective to take up and interpret the emergence of sexuality more directly in the transference and some of the risks to our patients when we ‘play safe’ and fail to do so. Most importantly, this paper aims to facilitate further thinking and discussion about an important but uncomfortable and easily neglected area of our work.  相似文献

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.  相似文献

This study analyzes temperamental and social correlates of 18-month-olds’ (N = 58) instrumental helping (i.e., handing over out-of-reach objects) and comforting (i.e., alleviating experimenter’s distress). While out-of-reach helping as a basic type of prosocial behavior was not associated with any of the social and temperamental variables, comforting was associated with maternal responsible parenting, day care attendance, and temperamental fear, accounting for 34% of the total variance in a corresponding regression model. The data of the present study suggest that, while simple instrumental helping seems to be a robust developmental phenomenon, comforting is associated with specific social experiences and child temperament that constitute interindividual differences and thereby help to explain the domain-specific development of prosociality.  相似文献

Maternal depression can significantly impact mothers’ sensitivity to their infants’ needs as well as infants’ social and emotional development. The still-face paradigm (SFP) is widely used to assess infants’ understanding of the contingency between their own behavior and that of their caregivers, as well as infants’ ability to self-regulate arousal levels during sudden changes in maternal responsiveness. Infants of clinically depressed mothers display blunted levels of negative affect compared to infants of non-depressed mothers during the still-face (SF) phase. However, little is known about whether individual differences in elevated, non-clinical levels of maternal depression similarly affect mother-infant interactions. The current study examines the longitudinal effects of non-clinical maternal depression on infant and maternal behaviors during the SFP. Infants (N = 63) were assessed at 5 and 9 months and maternal depression was assessed at 5 months using the Beck Depression Inventory (BDI). Infants of mothers with elevated levels of depression displayed less negative engagement during the SF phase compared to infants of mothers with lower levels of depression. This effect was present at 5 months, but not at 9 months. Findings demonstrate that non-clinical levels of maternal depressive symptomatology can have a significant impact on infants’ affective regulation during the first half of the first year of life, but this does not necessarily have a long-lasting influence later in infancy. Interventions may want to target mothers with non-clinical depression to promote healthy infant social and emotional development.  相似文献

In this pilot study, the effectiveness and feasibility of Parent-Child Interaction Therapy (PCIT) for decreasing disruptive behavior was evaluated in 17 young children with Autism Spectrum Disorder (ASD). PCIT is a behaviorally based play therapy which targets the parent-child relationship through live coaching of play interactions and the implementation of consistent discipline techniques. Following an average of 19 sessions, disruptive behavior as measured by multiple indices significantly decreased. Congruently, parents increased positive parental following skills and decreased negative parental leading skills across the course of treatment. In addition, parents reported increased levels of child functional communication and prosocial behavior. High levels of parent acceptability of the intervention were also noted. Effect sizes were medium to large across measured dependent variables, including parent report and behavioral observations. Implications for the clinical use of PCIT within an ASD population and future research with controlled outcome studies are discussed.  相似文献

Mothers’ attributions about children’s misbehavior were experimentally manipulated to examine causal relationships among attributions, mood, and behavior and assess whether suggestion can change mothers’ general perceptions. Forty mothers of children aged 33 to 71 months were primed with dysfunctional child-referent (child responsible) or environment-referent (situation caused) attributions before a parent-child interaction. Mothers in the dysfunctional child-referent condition placed greater responsibility on children, reported less positive mood and endorsed more overly reactive discipline, and their children displayed more negative mood and misbehavior. The experimental manipulation also affected mothers’ general child attributions. Understanding how attributions form and change has implications for parenting interventions.  相似文献
