Prenatal smoke exposure (PSE) is a risk factor for adverse outcomes in the offspring, including those affecting psychological development. However, it is uncertain whether these associations are the direct result of PSE or other confounding factors. The aim of this study was to examine the possible relationship between PSE and behavioral development in children at 7.5 years of age, considering several prenatal, neonatal and postnatal covariates. A cohort of 266 mother-child pairs was followed from the first trimester of pregnancy until the children reached 7.5 years of age. PSE was assessed using a questionnaire from prenatal clinical records and corroborated by plasma cotinine determinations in the first and second trimesters and in the cord. Mother-child pairs were classified into one of four groups: unexposed, exposed to passive smoking, first trimester active smoking only and active smoking throughout pregnancy. Child behavior was assessed using the Child Behavior Checklist for ages 6–18 and the Childhood Autism Spectrum Test. In multiple linear regression models, smoking during pregnancy was associated with higher scores in affective problems (β?=?0.298; p?=?0.004). No significant associations were found between smoking during pregnancy and externalizing problems. Findings indicate that PSE is negatively associated with behavioral development in childhood.

This systematic review aimed to examine sleep associations in a) typically developing children and their parents, and b) children with neurodevelopmental disorders and their parents. Literature search was conducted on PubMed, PsycINFO, EMBASE and Scopus databases for articles examining sleep associations between parents and children. Thirty studies were included in the final review. Based on the first aim, sleep associations between parents and typically developing children were observed for sleep quality, sleep duration and sleep efficiency. However, evidence for associations between sleepiness levels in parents and children and sleep schedules related to bedtime or waketime was limited. Based on the second aim, children with neurodevelopmental disorders and their parents reported greater sleep disturbances in comparison to typically developing children and their parents. The review concluded that sleep in parents and children is interrelated across a number of sleep parameters. It also revealed some preliminary evidence on bidirectionality in parent-child sleep, which warrants further examination. The review highlights the need to examine the mediating role of environmental factors on the interactions between parent-child sleep. Rigorous, longitudinal designs should be employed to explore the pathways through which parents may impact their children’s sleep and functioning and vice-versa.

Apathy is common in HIV, separable from depression, and has been associated with non-adherence to antiretroviral therapy (ART). We examined the associations between apathy and critical psychological determinants of ART adherence, as per the information-motivation-behavioral model, in 85 persons living with HIV. Apathy was measured using a composite of the apathy subscale of the Frontal Systems Behavioral Scale and the vigor-activation scale of the Profile of Mood States. Independent of major depressive disorder, apathy was related at small-to-medium effect sizes with motivation to adhere and self-efficacy for health-related decision-making and medication management, but not with HIV knowledge or medication management skills. These findings suggest that apathy plays a unique role in several critical health adherence determinants and support the importance of assessment and management of apathy to maximize health outcomes among individuals with HIV disease.

The purpose of this paper is to examine the relationship between attending arts and cultural activities and individual happiness. We classify arts and cultural activities into four categories according to their characteristics: visual arts, performing arts, movies, and sporting events. Our results show that arts and cultural activities have a positive relationship with individual happiness. More specifically, the coefficient for attending performing arts is the highest, and the fall in marginal utility of participation is the lowest for movies. In addition, the benefit from arts and cultural activities is greater in the low-income group than in the high-income group; however, visual arts activities are statistically significant in the high-income group. Through the interaction between household types and cultural activities, we find that the utility increments for performing arts and movies occur in the high-income group. Our results can provide insight for government organizations involved in the promotion of the arts and cultural activities.

Within the framework of modern evolutionary theory, arguments are reviewed that the nonlegal equivalent of aggressive criminal behavior may have evolved by natural selection among mammals, particularly primates, as part of their overall approach to reproduction. If so, the commission of aggressive crimes (or their nonlegal equivalent) by humans, and even efforts to prevent fellow social group members from being victimized by aggressive crimes, may also be partially explainable in natural selection terms. The plausibility of this deduction was explored, first, by specifying the three elements that a human act must have to be regarded as an aggressive crime. Summarily, these were that (1) injury to a victim must be a likely result of the act, (2) the act must be intended, and (3) the act must elicit negative responses from those witnessing it. The primate behavior literature was examined for evidence that some behavior of nonhumans met all three conditions. Affirmative results were obtained. Therefore, while further research is in order, human aggressive criminal behavior, as well as human efforts to control it, seem to have close parallels in other primates. This would be consistent with the notion that aggressive criminal behavior (along with its condemnation by fellow group members) is part of a social system produced and sustained by natural selection.  相似文献

The use of memory wallets to prompt factual information during conversations with day-care center volunteers was evaluated for four subjects with dementia. Memory wallets contained 15–20 pictures and sentences about familiar persons, places, and events that each subject had difficulty remembering. All subjects used the memory wallets to improve their conversations by increasing factual statements and decreasing ambiguous, unintelligible, and perseverative utterances. Volunteers decreased their use of questions and prompts during conversations in which subjects used their memory wallets. These results demonstrate the effectiveness of using volunteers to develop memory wallets and to encourage their use during conversations with day-care clients.  相似文献

Research evidence has shown that in childhood, a secure attachment to a reliable caregiver is important for future mental health and well-being. The theoretical and research basis for attachment theory continues to grow. As attachment theory has become more widely adopted there are challenges and opportunities both theoretically and in terms of its clinical use. Disordered attachment has been linked to psychopathology including internalising and externalising disorders. However, there are ongoing implications for researchers and clinicians as only the most extreme forms of attachment disorders are included in the current diagnostic systems. A wide range of reliable and validated observational assessments to classify attachment are available. Owing to the growing popularity of attachment-based interventions there is a need to develop assessments which are practical for use in clinical settings. The use of attachment-based parenting interventions in clinical settings is increasing as they have been found to be effective and relevant. This growth presents opportunities to further refine these interventions, so they are easy to deliver in clinical practice and tailored to different populations. Attachment-based interventions are being widely used in Australia, and this has led to a need to understand and adapt the theory, assessments, and interventions to this context. Attachment-based interventions demonstrate the importance of relationships and provide an important tool to support children and families. For psychologists here in Australia there are many opportunities to develop measures and interventions based on attachment theory that fit into the Australia context.  相似文献

This study used longitudinal survey data of Filipino American and Korean American youth to examine ways in which universal factors (e.g., peer antisocial behaviors and parent–child conflict) and Asian American (AA) family process variables (e.g., gendered norms) independently and collectively predict grade point average (GPA), externalizing, and internalizing problems. We aimed to explain the “Asian American youth paradox” in which low externalizing problems and high GPA coexist with high internalizing problems. We found that universal factors were extensively predictive of youth problems and remained robust when AA family process was accounted for. AA family process also independently explained youth development and, in part, the AA youth paradox. For example, gendered norms increased mental distress. Academic controls did the opposite of what it is intended, that is, had a negative impact on GPA as well as other developmental domains. Family obligation, assessed by family-centered activities and helping out, was beneficial to both externalizing and internalizing youth outcomes. Parental implicit affection, one of the distinct traits of AA parenting, was beneficial, particularly for GPA. This study provided important empirical evidence that can guide cross-cultural parenting and meaningfully inform intervention programs for AA youth.  相似文献
