Clinical Validation of the Swedish Version of the Quality of Life Inventory in Crime Victims with Posttraumatic Stress Disorder and a Nonclinical Sample

The Swedish version of the Quality of Life Inventory (QOLI) was cross-culturally validated with a crime victim sample (N = 53) with posttraumatic stress disorder (PTSD) and a nonclinical group (N = 100) with no lifetime and current psychiatric disorder from the general population in the Stockholm county of Sweden. The QOLI showed excellent internal consistencies in the clinical and the nonclinical sample. In addition, PTSD participants displayed a significantly lower self-perceived quality of life in 13 out of 16 domains of life than the nonclinical individuals. Furthermore, the QOLI was inversely correlated with interview and self-report measures of PTSD symptoms, depression, and anxiety. Overall, the results support the utility of the Swedish QOLI version as a potentially useful measure of self-perceived quality of life in Swedish clinical and nonclinical samples. The results are discussed in relation to the Swedish cross-cultural validation of the QOLI, methodological limitations and future directions.     

Cross‐cultural validation of factor structure in the Japanese Counselor Burnout Inventory

This article describes the cross‐cultural validation of the Counselor Burnout Inventory (CBI; Lee, Baker, Cho, Heckathorn, Holland, Newgent, Ogle, Powell, Quinn, Wallace & Yu, 2007 ) on a sample of professional counselors and psychotherapists in Japan. Confirmatory factor analysis was performed to examine the validity of the CBI with three models: a one‐factor model, a five‐factor model, and a second‐order model. The results showed that the five‐factor model was a better fit and more parsimonious than both the one‐factor model and the second‐order factor model. Additionally, the internal consistency reliability for the CBI subscale scores proved equivalent to that found for other populations (e.g. American and Korean). The results suggest that counselor burnout is not a unidimensional construct but a multidimensional construct. Implications and recommendations for future research are provided.     

Squeezing, striking, and vocalizing: Is number representation fundamentally spatial?

Numbers are fundamental entities in mathematics, but their cognitive bases are unclear. Abundant research points to linear space as a natural grounding for number representation. But, is number representation fundamentally spatial? We disentangle number representation from standard number-to-line reporting methods, and compare numerical estimations in educated participants using line-reporting with three nonspatial reporting conditions (squeezing, bell-striking, and vocalizing). All three cases of nonspatial-reporting consistently reproduced well-established results obtained with number-line methods. Furthermore, unlike line-reporting—and congruent with the psychophysical Weber–Fechner law—nonspatial reporting systematically produced logarithmic mappings for all nonsymbolic stimuli. Strikingly, linear mappings were obtained exclusively in conditions with culturally mediated elements (e.g., words). These results suggest that number representation is not fundamentally spatial, but builds on a deeper magnitude sense that manifests spatially and nonspatially mediated by magnitude, stimulus modality, and reporting condition. Number-to-space mappings—although ubiquitous in the modern world—do not seem to be rooted directly in brain evolution but have been culturally privileged and enhanced.     

Is Originality in the Eye of the Beholder? Comparison of Scoring Techniques in the Assessment of Divergent Thinking

Divergent thinking (DT) tests are among the most popular techniques for measuring creativity. However, the validity evidence for DT tests, as applied in educational settings, is inconsistent partly due to different scoring methods. This study explored the reliability and validity issues of various techniques for administering and scoring two DT tests. Results show distinct differences among several methods for scoring these DT tests and suggest that the percentage scoring method (i.e., dividing originality scores by fluency scores) may be the most appropriate scoring strategy. The potential impact on educational research and practice is discussed in detail.     

Young Children as Protagonists and the Role of Participatory, Visual Methods in Engaging Multiple Perspectives

How can the perspectives, insights and interests of young children, under 6 years‐old, be given status in processes of change? This paper will examine the contribution participatory and visual methods can make to enabling young children to document their experiences and to facilitate exchange with adults. Examples will be drawn from three research studies in educational settings which have developed a specific research method, the Mosaic approach (Clark and Moss 2001 ; Clark 2004 ; Clark 2005 ) which brings together visual and verbal research tools. This paper will discuss how researching with young children rather than on young children can redraw the boundaries between adults’ and children's roles in the research process including the relationship with the research audience.     

疼痛条件下时间目标对时距估计的影响

本研究采用冷压任务引发疼痛,以健康大学生为被试,试图探讨在疼痛条件下时间目标对时距估计的影响。结果发现：疼痛条件下的时距估计值小于非疼痛条件下时距估计值,疼痛条件下具体时间目标的时距估计值显著大于无目标时距估计值。临床上给患者提供具体的时间目标或许有助于他们应对疼痛。     

计划缺失设计——通过有意缺失让研究更高效

缺失值是社会科学研究中非常普遍的现象。全息极大似然估计和多重插补是目前处理缺失值最有效的方法。计划缺失设计利用特殊的实验设计有意产生缺失值, 再用现代的缺失值处理方法来完成统计分析, 获得无偏的统计结果。计划缺失设计可用于横断面调查减少(或增加)问卷长度和纵向调查减少测量次数, 也可用于提高测量有效性。常用的计划缺失设计有三式设计和两种方法测量。     

Development and validation of the Achievement Goal Scale for Youth Sports

ObjectiveThe objective was to develop and validate an achievement goal scale for young athletes that was aligned with the 2 (mastery/ego)×2 (approach/avoidance) achievement goal framework.MethodA total of 1675 male and female athletes ranging in age from 9 to 14 years participated in the AGSYS scale development and validation phases. Items having a readability level of grade 4 (age 9) or below were written and evaluated in a series of studies to assess the reliability, factorial validity, and construct validity of the Mastery and Ego scales.DesignBoth correlational and experimental methods were used to assess reliability and validity.ResultsExploratory and confirmatory factor analyses demonstrated factorial validity in samples of 9–10-, 11–12-, and 13–14-year-old athletes, and the subscales correlated in a predicted fashion with one another, with other sport and academic goal orientation measures and with several other theoretically relevant variables, including coach-initiated motivational climate, competitive trait anxiety, sport enjoyment, motivation, and self-esteem. Scores also changed significantly in response to a motivational climate coach intervention.ConclusionThe Achievement Goal Scale for Youth Sports (AGSYS) appears to be a reliable and valid measure of achievement goal approach orientations in children between the ages of 9 and 14 years. We were not successful in developing corresponding avoidance goal orientation scales that were not highly correlated, raising the possibility that children do not cognitively differentiate between mastery-avoidance and ego-avoidance orientations.
