Effortful control (EC) is a form of self‐regulation characterized by inhibition of dominant responses in favour of more adaptive subdominant responses. In the present study, temperamental antecedents in infancy were examined in relationship to toddler EC. Parents reported on infant temperament at 6, 8, 10, and 12 months, using the regulatory capacity/orienting (RCO) factor of the Infant Behavior Questionnaire‐Revised. Laboratory indicators of this temperamental construct were also collected at each time point via the Temperament Laboratory Assessment. Relations between changes in temperament across the first year of life and toddler EC (mean age = 22 months) were examined using multilevel modelling. Parent‐reported RCO and the component subscale of cuddliness more specifically were the only temperamental variables that prospectively predicted toddler EC.

Complicated grief (CG) is one of the central themes in bereavement research and advanced clinical practice today. Using a mixed-methods approach, we wanted to learn (a) what tools Canadian practitioners used to identify or diagnose CG and (b) what interventions or strategies they used to address CG. Sixty-three professionals responded to our survey. There were no straightforward answers to these questions: the state-of-the art of CG in Canada is, in fact, complicated. Practitioners used a wide assortment of tools and strategies with no consensus on any one approach or tool. Building a Canadian CG community of practice was recommended.  相似文献

This article examines the identity horizons of postsecondary students in Finland—a country in which social welfare provisions buffer education-to-work transitions—comparing their identity horizons to those previously reported for U.S. and Japanese students. Confirmatory factor analyses revealed scalar invariance of the Finnish version of the Identity Horizons Scales with the English and Japanese versions. Latent mean comparisons found that Finnish students had the broadest educational and work horizons, and the lowest education-to-work identity anxiety. Finnish men reported lower levels of educational horizons and higher levels of identity anxiety than Finnish women, replicating previous findings. Social class differences were also detected, with higher levels of identity anxiety and narrower educational horizons among those whose parents had no postsecondary education. Based on the apparent impacts on identity development of the different educational policies in the three countries, results are discussed in terms of policy implications supporting more effective education-to-work transitions.  相似文献

Although effective treatments for obsessive–compulsive disorder (OCD) exist, there are significant barriers to receiving evidence-based care. Mobile health applications (Apps) offer a promising way of overcoming these barriers by increasing access to treatment. The current study investigated the feasibility, acceptability, and preliminary efficacy of LiveOCDFree, an App designed to help OCD patients conduct exposure and response prevention (ERP). Twenty-one participants with mild to moderate symptoms of OCD were enrolled in a 12-week open trial of App-guided self-help ERP. Self-report assessments of OCD, depression, anxiety, and quality of life were completed at baseline, mid-treatment, and post-treatment. App-guided ERP was a feasible and acceptable self-help intervention for individuals with OCD, with high rates of retention and satisfaction. Participants reported significant improvement in OCD and anxiety symptoms pre- to post-treatment. Findings suggest that LiveOCDFree is a feasible and acceptable self-help intervention for OCD. Preliminary efficacy results are encouraging and point to the potential utility of mobile Apps in expanding the reach of existing empirically supported treatments.  相似文献

Objective: The aim of this study was to examine the effects of experiential avoidance (EA) on the indirect relationship of chronic pain patients’ illness representations to pain interference, through pain catastrophising

Design and main outcome measure: The sample consisted of 162 patients diagnosed with an arthritis-related or a musculoskeletal disorder. The effects of EA on the pathway between illness representations, pain catastrophising and pain interference were examined with PROCESS, a computational tool for SPSS

Results: After controlling for patient and illness-related variables and pain severity, the ‘illness representations–pain catastrophising–pain interference’ pathway was interrupted at the higher levels of EA. The reason was that, at the high levels of EA, either the relation of illness representations to pain catastrophising or the relation of pain catastrophising to pain interference was not statistically significant.

Conclusion: The findings indicate that EA is not a generalised negative response to highly aversive conditions, at least as far as the factors examined in this study are concerned. EA may rather reflect a coping reaction, the impact of which depends on its specific interactions with the other aspects of the self-regulation mechanism. At least in chronic pain, EA should become the focus of potential intervention only when its interaction with the illness-related self-regulation mechanism results in negative outcomes.  相似文献

Purpose

The purpose of this study was to investigate the relationship between work engagement and multiple dimensions of employee performance, as mediated by open-mindedness.

Design/Methodology/Approach

Survey data were obtained from 186 employees of a food processing plant and the findings were cross-validated in an independent convenience sample (N = 308).

Findings

SEM analyses revealed that the more engaged the employees were, the more they displayed extra-role and in-role performance. As expected, these associations were partially mediated by open-mindedness. Results were ambiguous for counterproductive performance showing a direct negative relation between engagement and counter productivity, and an indirect, positive relation through open-mindedness.

Implications

With its systematic look at the relation between engagement and multiple indicators of performance, the current study shows why it is important for both employers and employees to invest in engaged employees: there is a relationship with better performance which can partly be explained by the fact that engagement is associated with open-mindedness. This may help to inform organizations under what circumstances engagement leads to positive or negative forms of performance. Vice versa, a decrease in the multiple indicators of performance may signal organizations to look after their employees' mental health, i.e., engagement.

Originality/Value

This is one of the first studies to include multiple dimensions of employee performance in relation to work engagement. Moreover, it is one of the first studies that focus on the underlying psychological process that might explain for this relationship.

Previous research showed that in primary school, children’s intelligence develops continually, but creativity develops more irregularly. In this study, the development of intelligence, measured traditionally, i.e., operating within well-defined problem spaces (Standard Progressive Matrices) was compared with the development of intelligence operating in ill-defined problem spaces (Creative Reasoning Task) and the development of creativity (Test of Creative Thinking-Drawing Production), in primary school children (N = 175) across four grade levels. Results showed that problem space matters: Traditional intelligence test scores increased regularly with grade level, whereas creativity, as well as intelligence operating in an ill-defined problem space, developed irregularly but similarly. This suggests that when creativity is fostered, intelligence’s ability to operate in ill-defined problem space may be fostered, likewise.  相似文献

The three major hereditary cancer syndromes in Latinos (Hereditary Breast and Ovarian Cancer, Familial Adenomatous Polyposis and Lynch Syndrome) have been shown to exhibit geographic disparities by country of origin suggesting admixture-based disparities. A solid infrastructure of clinical genetics geared towards diagnosis and prevention could aid in reducing the mortality of these cancer syndromes in Latinos. Currently, clinical cancer genetic services in Latin America are scarce. Moreover, limited studies have investigated the mutational spectrum of these cancer syndromes in Latinos resulting in gaps in personalized medicine affecting diagnosis, treatment and prevention. The following commentary discusses available genotype and clinical information on hereditary cancer in Latinos and highlights the limited access for cancer genetic services in Latin America including barriers to genetic testing and alternatives for providing better access to genetic services. In this review, we discuss the status of clinical genetic cancer services for both US Latinos and those Latinos living in Latin America.  相似文献

The Child Mental Health Service (CMHS) is an Australian primary care program introduced in July 2010 to provide mental healthcare to children who have, or are at risk of, developing psychological disorders. The Australian Government provided supports (e.g., training for mental health professionals), resources (e.g., funding for positions devoted to fostering inter-agency linkages or partnerships) and various flexibilities in service delivery. This study aimed to explore the processes used in the implementation of the CMHS in order to achieve its objectives of delivering a high quality standard of service, and forging linkages and support networks with other relevant health and non-health agencies. Structured interviews were conducted with 20 program administrators, six referring professionals and eight mental health professionals. Interviews were recorded, transcribed and analysed for themes using NVivo. The CMHS appears to have made good progress towards achieving its objectives by implementing processes that facilitated the delivery of a high quality service (e.g., engaging appropriately qualified, and encouraging additional training and clinical support for, mental health professionals; employing quality assurance mechanisms and clinical governance arrangements) and establishment of inter-agency linkages (e.g., devoting a professional role—Coordination and Liaison—to this purpose). Provider perspectives suggest that the CMHS has had a positive impact on children and their families. Comparable countries implementing primary mental health programs for children may benefit from considering similar additional supports (e.g., training for mental health professionals), resources (e.g., funding positions devoted to fostering service inter-agency linkages) and service delivery flexibilities as those available in the CMHS.  相似文献

Previous studies have found that a stressful observational context challenges the mother-child relationship, thus highlighting negative interactive behavior. However, the impact of observational context has only been investigated in infants and preschoolers without specifically using the Emotional Availability Scales. Nor have they explored whether the association of mother-child interaction with children’s emotional or behavioral problems depends on the observational context. We observed 140 mothers and their five to 12-year-old children in non-stressful free play and in a stressful task context. In general, dyads showed higher emotional availability in the task context compared to the free play. Specifically, mothers showed higher levels of Sensitivity, Structuring and Nonhostility, but lower levels of Nonintrusiveness during the task compared to the free play context; children showed higher levels of Responsiveness during the task than during free play. After controlling for dyadic stress, contextual effects decreased for all dimensions of emotional availability. The association of mother-child interaction with child problem behavior depended on the observational context. Specifically, we found maternal emotional availability during free play to be more strongly associated with child problem behavior than during the stressful task; however, emotional availability of the child was more strongly associated with problem behavior when obtained during the task. We conclude that context impacts on mother-child interactive behavior and also on the association of mother-child-interaction and child behavior. Stress is a relevant contextual factor influencing mother-child interactive behavior.  相似文献
