This study examined the effects of micronutrients on children with clinically elevated stress and anxiety 23–36 months after experiencing a natural disaster (a major earthquake). A single-case multiple-baseline design allocated 14 children (7 males, 7 females; aged 8–11 years; 10 with formal anxiety-disorder diagnoses) randomly to 1, 2 or 3 week baselines. Participants then took eight capsules/day of a micronutrient formula (EMPowerplus) during an 8-week open-label trial. Assessment instruments were the Children’s Global Assessment Scale (CGAS), the Screen for Child Anxiety-Related Emotional Disorders (SCARED), the Pediatric Emotional Distress Scale (PEDS), and the Revised Children’s Manifest Anxiety Scale (RCMAS). Symptom severity declined slightly in baseline for some children and declined much more during intervention for all children. Effect sizes at end of treatment were ?1.40 (RCMAS), ?1.92 (SCARED), +1.96 (CGAS), and ?2.13 (PEDS). Modified Brinley plots revealed decreases in anxiety and improvements in overall functioning for 10 out of 11 completing participants. Side effects were mild and transient. The study provided evidence that treatment with a dietary supplement containing micronutrients reduced children’s post-disaster anxiety to a clinically significant degree. Future placebo-controlled randomized-controlled trials and treatment-comparison research is recommended to determine if this is true of anxiety in general.  相似文献

The dominant technological trajectory in vehicle design brings with it similarly dominant driver performance issues in regard to vehicle feedback and driver situational awareness (SA). Three experiments are reported in this paper that describe not only the effects on driver SA of manipulations of vehicle feedback but also illuminate issues concerned with SA measurement methods and contexts. The findings suggest that current trends in vehicle design may contribute little towards a driver’s SA and, in fact, may actually show a generalized trend towards decreasing it. The efficacy of verbal protocol and probe recall SA measurement techniques is noted in terms of observing this effect. On the other hand, a concerning dissociation occurred with findings from a self-report measure of SA. Drivers appear to show a concerning lack of self-awareness of their SA and, indeed, any shortfall in it.  相似文献

Social Anxiety Disorder (SAD) is a heterogeneous and distressing problem for many children and youth. This review focuses on the etiology and maintenance of SAD, and examines research findings in several key areas of investigation: genetic or hereditary factors (twin and family studies), temperament characteristics (behavioural inhibition), and parent–child interactions (attachment, parenting styles). It is concluded that genetic influences, behavioural inhibition, and parent–child interactions play significant and interactive roles in the development and maintenance of SAD. Other influences such as peer relationships, social skills deficits, and traumatic experiences are also acknowledged. Ultimately, an understanding of such pathways should facilitate effective early screening and intervention of children at risk for severe social anxiety.  相似文献

Coping strategies endorsed by adolescents in dealing with a potential threat to their health were assessed in a study which investigated components of protection motivation theory. Year 9 and 10 high school students were presented with information about cardiovascular disease risk and the role of exercise in maintaining cardiorespiratory fitness. Three components specified by the theory were manipulated: response efficacy (effectiveness of exercise in preventing cardiovascular disease), response costs (costs associated with taking up a regular program of exercise) and self-efficacy (belief in ability to carry out a program of exercise) in a 2 × 2 × 2 factorial design with two levels (high vs. low) of each variable. It was hypothesized that such information would affect participants' perceptions of response efficacy, response costs, self-efficacy, and their selection of coping strategies. Six dependent variables were investigated: two adaptive coping strategies (behavioral intention to exercise, rational problem solving) and four maladaptive strategies (avoidance, wishful thinking, hopelessness, arid fatalism). Manipulation checks found significant differences between the high and low conditions of each independent variable. Adaptive strategies were strongly endorsed, whereas endorsement of the maladaptive strategies ranged from minimal to complete disagreement. Participants in the high self-efficacy condition indicated stronger intentions to exercise. Students in the low response efficacy condition demonstrated more endorsement of hopelessness and fatalism than did students in the high response efficacy condition. When exercising status was included as a fourth independent variable, it was found that active adolescents endorsed the adaptive coping strategies more strongly than did inactive adolescents. The cognitive coping strategies adopted by adolescents when dealing with perceived threats to their health may be influenced by information on the efficacy of relevant behavior, by perceptions of their ability to perform such behavior, and by their actual involvement with the behavior of concern.  相似文献

34 male and 34 female hospitalized psychiatric patients were divided into field-independent and field-dependent groups on the basis of rod-and-frame test performance and their MMPI scores were compared. A multiple discriminant analysis followed by a series of 2 X 2 factorial analyses of variance was used to assess the results. As in previous studies, more similarities than differences were found between the two cognitive styles. However, field-independent subjects tended to be more unconventional, aggressive, antisocial, and perhaps defensive than field-dependent subjects. Explanations of results were explored in reference to previous findings.  相似文献

Groups of digits were presented binaurally and dichotically to subjects who were asked to recall them. Different rates and patterns of presentation were used, the design being based on that of Broadbent (1954). Broadbent's findings in this field were confirmed. If subjects are presented with simultaneous pairs of digits at a rate of 2 pairs per second dichotically, they cannot recall them if they are asked to alternate between the ears. If however the presentation is staggered, so that although the rate is constant the signals do not overlap, subjects can recall alternately from the two ears. It is suggested that these findings are better interpreted as an interference effect, not a rate effect. Criticism is offered of similar designs to measure “switching rate”. Criticism is also offered of Broadbent's estimate of “perception time” in such experiments. An analysis of the quantity and type of errors made by subjects is given, which suggests that Broad-bent's theory of a short term store on the peripheral side of a selective filter is in need of revision.  相似文献

Ethnic minority psychologists were found to be prolific mentors of both ethnic minority and European American protégés. Mentoring benefits were not related to ethnic similarity.  相似文献

The Saturday Mothers (Cumartesi Anneleri) are a group that has gathered in Istanbul for a 30-min sit-in every Saturday since 1995 seeking justice for forced disappearances and political murders in Turkey. What started with a group of approximately 30 mainly family and close relatives of those who disappeared has grown to include thousands of participants. The initial protests were composed predominantly of mothers of victims, but over the past 28 years other relatives, including children, have joined the vigils. In many cases, those children then continue to participate and join the social movement. We are particularly interested in the Saturday Mothers' ability to sustain participation in weekly collective action, including the ways in which intergenerational transmission shapes and encourages this action. Semi-structured interviews were conducted with 19 members of the Saturday Mothers. Analysis of participants' narratives and experiences included three main themes: family as a model, shared experiences, and functions of the movement. Findings highlight the complex interplay between familial influences, collective memory, and the formation of the Saturday Mothers' identity.  相似文献
