The complexity of homeless service users’ characteristics and the contextual challenges faced by services can make the experience of working with people in homelessness stressful and can put providers’ well‐being at risk. In the current study, we investigated the association between service characteristics (i.e., the availability of training and supervision and the capability‐fostering approach) and social service providers’ work engagement and burnout. The study involved 497 social service providers working in homeless services in eight different European countries (62% women; mean age = 40.73, SD = 10.45) and was part of the Horizon 2020 European study “Homelessness as Unfairness (HOME_EU).” Using hierarchical linear modeling (HLM), findings showed that the availability of training and supervision were positively associated with providers’ work engagement and negatively associated with burnout. However, results varied based on the perceived usefulness of the training and supervision provided within the service and the specific outcome considered. The most consistent finding was the association between the degree to which a service promotes users’ capabilities and all the aspects of providers’ well‐being analyzed. Results are discussed in relation to their implications for how configuration of homeless services can promote social service providers’ well‐being and high‐quality care.  相似文献

Understanding public opinion about the causes of pedophilia and/or child sex offending is vital, as the views of the public influence how governments respond to sexual offenders. However, little research has been undertaken on this topic. This study addresses this gap by examining the causes that members of the public ascribe to pedophilia and/or child sexual abuse using qualitative data from online forums. The etiological accounts that the public gave provide important information for those developing public prevention policies and/or education campaigns about child sexual abuse. Key implications of these etiological explanations are analyzed in this regard.  相似文献

Goal pursuits are strongly influenced by romantic partners, and a partner's instrumentality to goals may be particularly important for goal pursuit. This study examined the effects of partner instrumentality on goal‐related effort, goal progress, goal commitment, and relationship satisfaction over time. It also examined whether relationship satisfaction moderated the effects of partner instrumentality on goal pursuit processes. Newly dating romantic partners (N = 59 couples) reported on their goals and relationship satisfaction at two assessments 3 months apart. Multilevel models indicated that partner instrumentality predicted increases in progress over time but only for those high in relationship satisfaction. Partner instrumentality also predicted increases in one's own relationship satisfaction but was unrelated to changes in the partner's satisfaction. These findings suggest that partner instrumentality benefits increased goal progress, particularly for those with satisfying relationships, and further increases relationship satisfaction.  相似文献

Extreme levels of certain temperament traits can be early markers of different developmental pathways of attention-deficit/hyperactivity disorder (ADHD). However, the long-term utility of using these traits as predictors of ADHD is not fully known. This study includes 64 male adolescents (M age = 13.5), who have been followed since birth as part of a longitudinal study. The primary aim was to test effortful control (EC), activity level, and anger, measured in early childhood – both with mother’s reports and laboratory assessments –as predictors of ADHD symptoms in adolescence. Further, we investigated the specificity of this prediction to the different ADHD symptom domains. The results demonstrated that early temperament dimensions of EC and activity level were predictive of ADHD symptoms about 10 years later, when the participants reached adolescence. Moreover, activity level showed specificity only to hyperactivity-impulsivity symptoms whereas EC was a predictor of the two symptom domains. Anger had a predictive correlation with ADHD symptoms; however, it did not have a unique predictive contribution. These results emphasize the relevance of EC and activity level in the developmental course of ADHD. Identification of early risk factors can lead to more efficient design and implementation of intervention programs.  相似文献

Parent–child relationships play an important role in successful academic outcomes. Previous research suggests that the association between parent–child relationships and offspring’s academic achievement may be mediated by offspring’s self-efficacy levels, although these relationships are not fully understood. Furthermore, the association between family support and academic outcomes is well-documented among European Americans, but not across cultures. Therefore, the present study examined how parent–child relationship quality relates to young adults’ academic achievement and self-efficacy among European Americans and Asian Americans. Participants were 258 undergraduate students (85 male, 173 female) who completed a survey. Overall, both parent–child relationships and self-efficacy were significantly associated with the offspring’s academic performance, and self-efficacy mediated the relationship between parent–child relationships and school outcomes. Ethnicity moderated these relationships: among European American students, quality of parent–child relationships was not associated with self-efficacy level whereas for Asian Americans, parent–child relationships were associated with self-efficacy. These findings suggest that European American college students’ self-efficacy levels are less dependent on parent–child relationship quality, but for Asian Americans college students it may be important for educators to facilitate communication and family support so students may continue to use family as a resource for self-efficacy levels.  相似文献

In this longitudinal study, we examined whether children differ in their susceptibility to harsh and responsive parenting as reflected in their externalizing and prosocial behaviour two years later. We focused on three potential susceptibility markers assessed during middle childhood: Negative emotionality, impulsivity, and effortful control. Participants were 120 Dutch children (6–11 years old; 54% girls). Parenting was assessed using both observations and self‐report questionnaires. Parental responsiveness predicted decreased externalizing behaviour two years later among children high on impulsivity (in case of observed responsiveness) or low on effortful control (in case of observed and self‐reported responsiveness) but not among children low on impulsivity or high on effortful control. Observed harsh parenting predicted decreased prosocial behaviour, especially among children with average or high negative emotionality. The findings support a diathesis–stress model more than they do a differential susceptibility model. High impulsivity seemed to be a vulnerability factor, predicting increased externalizing behaviour when parents lacked responsiveness. Also, high negative emotionality served as a vulnerability factor, predicting decreased prosocial behaviour when parents were harsh, while low negative emotionality served as a protective factor, buffering against decreased prosocial behaviour. Finally, low effortful control might operate as a vantage‐sensitivity factor, predicting decreased externalizing behaviour when parents were responsive.
