基于直线临摹的ADHD儿童眼手协调能力研究

ADHD儿童在精细动作方面通常伴随眼手协调运动障碍。以往采用的研究方法多为定性研究,且未在ADHD儿童的运动协调性与同龄正常儿童的差异上得出统一结论。本研究针对精细动作中眼手协调能力进行定量分析。实验要求被试在计算机触摸屏上分别临摹水平线、垂直线和斜线,通过记录临摹直线与呈现直线的偏差程度和拐点数,以分析ADHD儿童眼手协调能力与正常儿童之间的差异。结果表明,ADHD儿童在眼手协调和空间知觉能力上与正常儿童存在显著性差异。此外,本研究表明,改进的定量方法具有良好的可行性。     

早期乳腺癌患者术后心理状况研究

早期乳腺癌的检出率越来越高,关注治愈率同时,人们越来越关心患者术后的心理状态及生活质量.本文对保乳术及根治术后5年患者进行心理调查.保乳组患者术后心理障碍发生率明显低于根治组.保乳组患者术后心理状况影响因素主要为术后美容效果,而根治组患者心理障碍发生率与年龄、职业、家庭收入相关.两种手术方式对患者5年生存率及无病生存率的影响无明显差异,所以对于早期乳腺癌患者,在符合保乳原则的前提下,保乳手术是一种既安全又能提高生活质量的手术方式.     

An effectiveness trial of a new enhanced dissonance eating disorder prevention program among female college students

Objective

Efficacy trials indicate that a dissonance-based prevention program in which female high school and college students with body image concerns critique the thin-ideal reduced risk factors, eating disorder symptoms, and future eating disorder onset, but weaker effects emerged from an effectiveness trial wherein high school clinicians recruited students and delivered the program under real-world conditions. The present effectiveness trial tested whether a new enhanced dissonance version of this program produced larger effects when college clinicians recruited students and delivered the intervention using improved procedures to select, train, and supervise clinicians.

Method

Young women recruited from seven universities across the US (N = 408, M age = 21.6, SD = 5.64) were randomized to the dissonance intervention or an educational brochure control condition.

Results

Dissonance participants showed significantly greater decreases in risk factors (thin-ideal internalization, body dissatisfaction, dieting, negative affect) and eating disorder symptoms versus controls at posttest and 1-year follow-up, resulting in medium average effect size (d = .60). Dissonance participants also reported significant improvements in psychosocial functioning, but not reduced health care utilization or unhealthy weight gain.

Conclusions

This novel multisite effectiveness trial with college clinicians found that the enhanced dissonance version of this program and the improved facilitator selection/training procedures produced average effects that were 83% larger than effects observed in the high school effectiveness trial.     

Exposure Therapy for Posttraumatic Stress Disorder: A Meta-Analysis

This meta-analysis compares the findings of empirical studies that employ either a traditional form of cognitive–behavioral-based exposure therapy or virtual reality exposure therapy (VRET) for the treatment of posttraumatic stress disorder (PTSD) to determine which is more viable and effective. Statistical analyses were performed on 26 studies to determine pre- to posttreatment effect sizes and interactions. Results demonstrated a trend toward significance in favor of traditional exposure therapy showing lower posttreatment PTSD. Limitations included a restricted number of relevant studies; future research on VRET for PTSD should orient more to experimental designs, larger samples, and increased use of control groups.     

Associations Between Time Since Event and Posttraumatic Growth Among Military Veterans

Despite efforts to understand the antecedents, correlates, and consequences of posttraumatic growth (PTG), the role of time since a traumatic event (time since event) vis-à-vis PTG is not well understood. Part of a larger project exploring experiences following emotionally distressing events among military veterans (N = 197) using Amazon’s Mechanical Turk (Mturk), in the current study, we sought to clarify associations between the time since event and PTG. We used cluster-analytic techniques and analyses of variance to (a) determine the number of clusters, and (b) assess differences in core constructs of PTG and participant characteristics across clusters. Results revealed 4 significantly different groups (i.e., clusters) characterized by differential associations between PTG and time since event. These groups also differed significantly in challenge to core beliefs, level of PTSD symptoms, intrusive and deliberate rumination, and age. The immediate moderate-growth group (Cluster 1) experienced moderate levels of PTG over shorter periods of time, severe PTSD symptoms, and was significantly younger. The low-growth group (Cluster 2) was characterized by minimal PTG, regardless of time, the least challenge to core beliefs, and low amounts of intrusive and deliberate rumination. The long-term small-growth group (Cluster 3) was primarily characterized by small amounts of PTG over longer periods of time. The high-growth group (Cluster 4) was characterized by high PTG, regardless of time, greater challenge to core beliefs, the highest amount of deliberate rumination, and the highest number of PTSD symptoms. Findings underscore heterogeneity within military veterans’ experiences of PTG over time.     

Spatial affect learning restricted in major depression relative to anxiety disorders and healthy controls

Detecting and learning the location of unpleasant or pleasant scenarios, or spatial affect learning, is an essential skill that safeguards well-being (Crawford & Cacioppo, 2002). Potentially altered by psychiatric illness, this skill has yet to be measured in adults with and without major depressive disorder (MDD) and anxiety disorders (AD). This study enrolled 199 adults diagnosed with MDD and AD (n=53), MDD (n=47), AD (n=54), and no disorders (n=45). Measures included clinical interviews, self-reports, and a validated spatial affect task using affective pictures (IAPS; Lang, Bradley, & Cuthbert, 2005). Participants with MDD showed impaired spatial affect learning of negative stimuli and irrelevant learning of pleasant pictures compared with non-depressed adults. Adults with MDD may use a “GOOD is UP” heuristic reflected by their impaired learning of the opposite correlation (i.e., “BAD is UP”) and performance in the pleasant version of the task.     

Differential response patterns to disgust-related pictures

ABSTRACT

In the present study, attentional bias was investigated as a potential predisposing mechanism for the contamination-related subtype of obsessive-compulsive disorder (C-OC disorder). Fifty healthy participants with varying degrees of subclinical C-OC symptoms performed a visual search task to measure differential attentional biases elicited by neutral, disgust-, and fear-specific pictorial material. Participants had to find a target picture within five neutral distractor pictures randomly presented on different locations in an array. The task was to decide whether the array contained an unpleasant target picture or not. In randomly-selected emotional trials, participants were further asked about the content of the picture and the confidence of their answer. The results show that the reaction times significantly differed between the emotional and neutral pictures. Participants were significantly more confident in answering questions referring to fear compared to disgust pictures. This effect was marginally amplified in participants with higher C-OC symptoms. We discuss the results within the framework of the cost and benefit hypothesis, which postulates that disgust evolutionarily elicits stronger uncertainty compared to fear, owing to the ambiguous nature of the stimuli. Increased uncertainty might be an important but underestimated factor for pathological disgust experience, such as in obsessive-compulsive disorder.     

Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder

Lambek, R., Trillingsgaard, A., Kadesjö, B., Damm, D. & Thomsen, P. H. (2010). Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder. Scandinavian Journal of Psychology 51, 540–447. The aim of the present study was to examine gender differences in children with inattention, hyperactivity, and impulsivity on the Five to Fifteen (FTF) parent questionnaire. First, non‐referred girls (n = 43) and boys (n = 51) with problems of attention and hyperactivity‐impulsivity and then clinic‐referred girls (n = 35) and boys (n = 66) with hyperkinetic disorder (HKD) were compared on the FTF. Results suggested that non‐referred boys were more hyperactive‐impulsive than non‐referred girls, whereas clinic‐referred boys and girl with HKD were more similar than dissimilar on the FTF questionnaire. Secondly, it was examined whether the application of gender mixed norms versus gender specific norms would result in varying proportions of clinic‐referred children with HKD being identified as impaired on the subdomains of the FTF questionnaire. Based on results it was concluded that the use of a gender mixed normative sample may lead to overestimation of impairment in boys with HKD, but the type of sample applied to define impairment on the FTF should depend on the purpose for applying the questionnaire.     

Effects of focus of attention on physiological,behavioural, and reported state anxiety in repressors,low-anxious,high-anxious,and defensive high-anxious individuals

Abstract

Discrepancies between physiological activity, behavioural anxiety, and self-reported anxiety were examined when focus of attention was manipulated in a public speech task for four groups of individuals: repressors, low-anxious, high-anxious, and the defensive high-anxious. They were exposed to self-focus (when their behaviour was socially evaluated) and other-focus (when their behaviour was not socially evaluated) conditions. Repressors had consistently the lowest level of self-reported anxiety, but had consistently greater physiological activity in all conditions and greater behavioural anxiety in the self-focus condition. The high-anxious showed the opposite pattern, i.e. their self-reported anxiety was greater than their physiological and behavioural anxiety, and this finding was significant in the self-focus condition. No significant pattern of discrepancy was found for the low-anxious or defensive high-anxious groups. The findings are discussed and interpreted within the framework of recent cognitive models of anxiety.
