Infant mental health practice requires the performance of intense emotional labor. Professionals comprising the infant mental health (IMH) field are largely women at seminal points in adult life‐span development. The purpose of this article is to explore the day‐to‐day challenges faced by clinical infant mental health professionals and their perspectives on the supports available for effective job performance. We review reflective supervision as a long‐cherished professional support in the IMH field designed to hold the practitioner's fears, worries, and ambivalence, so that she may return to the work fortified to remain in therapeutic alliance with families despite unsolvable problems and an unknowable future (Weatherston, D., 2009). Yet, we propose that reflective supervision alone may not be an adequate protective measure for a workforce performing intensive emotional labor for extended periods and therefore at potentially increased risk for burnout and high turnover (Hochschild, A.R. 1983 ; C. Maslach, 1982 , C.M. Brotheridge & A.A. Grandey, 2009; A.S. Wharton, 2009 ). We suggest that structural factors concerning organizational culture, flexibility in scheduling, and professional growth and versatility bear deeper examination for their merits in supporting the IMH workforce. Finally, we contend that the overrepresentation of women in practitioner positions in IMH leaves an empirical gap where little is known about the experience of male IMH practitioners and the ramifications of their performance of emotional labor.  相似文献

Despite widespread belief in the early childhood field of the benefits of reflective supervision, there has been limited empirical evidence to support the effectiveness of reflective supervision for home visitors and the children and families they serve. The present study examined the psychometric properties of four adapted self‐report measures assessing supervisors’ reflective supervision capacities; the study also investigated whether these measures captured change in reflective capacity over time as supervisors participated in professional development activities focused on reflective supervision. Results from 33 participants (home visiting supervisors and program managers) suggested that three of the four measures demonstrated acceptable internal consistency, and these three measures were correlated with each other. Two of these measures also captured significant change over time. Finally, there was some evidence that those with less education demonstrated more substantial improvement in their reflective supervision capacities than did those with an advanced degree. Findings provide initial evidence for reliable, efficient, and cost‐effective supervisor self‐report measures that could be used in research and program evaluation to assess change in supervisor reflective capacity over time.  相似文献

Home‐visiting programs have gained increasing importance in family‐centered prevention and intervention. However, few studies have examined the mechanisms underlying early intervention treatment effects. The goal of this study is to analyze the mediating role of maternal sensitivity in enhancing language development with the home‐visiting program Parents as Teachers (PAT). Data were collected and analyzed within the ongoing, long‐term ZEPPELIN study, a randomized controlled trial with 251 participating at‐risk families. Via longitudinal mediation analysis, we examined whether effects of the PAT on receptive and expressive language outcomes at 24 and 36 months were mediated by maternal sensitivity at 12 months. Within a moderated mediation framework, we investigated whether the level of family psychosocial stress affects this mediation. Results showed that intervention effects on language outcomes are mediated by maternal sensitivity—weakly and through specific pathways. Moderation and moderated mediation analyses indicated that effects of the PAT and also specific mediation effects increase with the level of psychosocial stress. Implications of the results for practice are discussed.  相似文献

肠促胰素对2型糖尿病胰岛功能的影响   总被引:1,自引:1,他引:0  
胰岛β细胞功能障碍是2型糖尿病的重要发病机制之一,而现有治疗手段保护β细胞功能作用有限。最新的研究发现,肠促胰素不仅能够改善口细胞功能,而且能够避免低血糖、体重增加等不良反应,是治疗2型糖尿病的新途径。本文通过回顾公开发表的临床研究,对2型糖尿病口细胞功能、传统治疗及肠促胰素对β细胞功能的保护及延缓疾病进展作用进行了综...  相似文献

T1G3膀胱癌有高复发和进展倾向,选择恰当的治疗方法成为难题。使用BCG治疗可促肿瘤进展和转移,但可保留膀胱。膀胱切除也许提供了最好的治疗方案,但膀胱切除仍会复发且具有手术风险,且被认为是过度治疗。此文从哲学角度来探讨T1G3膀胱癌的治疗方法,以便为临床实践和进一步的研究提供思路。  相似文献

Mood in humans is a complex phenomenon that integrates emotion (e.g. happiness and sadness), cognition, perception, ideation, and action in a coherent manner. In bipolar disorder extremes of mood (up or down) occur outside the normal range, in which all the above functions are coherently affected. Mood is controlled by a series of separate but interactive brain circuits that involve much of the brain, but particularly the limbic system. The question addressed in this paper is whether the coordination of all these separate systems into one coherent functional mood is mediated by non-linear dynamics acting between these systems as equal participants; or whether it is affected by a single master regulator controlling the others. The possible roles, as master regulators, of non-linear dynamically linked populations of neurons, and of the C1–C3 adrenergic nuclei in the medulla is discussed.  相似文献

When two targets are presented in rapid succession, identification of the first is nearly perfect, while identification of the second is impaired when it follows the first by less than about 700 ms. According to bottleneck models, this attentional blink (AB) occurs because the second target is unable to gain access to capacity-limited working memory processes already occupied by the first target. Evidence for this hypothesis, however, has been mixed, with recent reports suggesting that increasing working memory load does not affect the AB. The present paper explores possible reasons for failures to find a link between memory load and the AB and shows that a reliable effect of load can be obtained when the item directly after T1 (Target 1) is omitted. This finding provides initial evidence that working memory load can influence the AB and additional evidence for a link between T1 processing time and the AB predicted by bottleneck models.  相似文献
