中国大学生网络成瘾倾向问卷的初步研究

网络成瘾是一种对互联网络的心理依赖,包括网络关系成瘾、网络娱乐成瘾、信息搜集成瘾三种类型。被试为中国重庆三所高校的大学生675人。对其中随机抽取的390份数据进行探索性因素分析,得出初步的因素结构为：网络关系成瘾倾向包括了问题、依附、认知偏差和失控四种倾向;网络娱乐成瘾倾向和信息搜集成瘾倾向包括问题、依附和失控倾向。得到较好的问卷内部一致性系数、分半信度、内容效度和结构效度。对余下285份数据进行验证性因素分析,得到较好的模型拟合指数。相关关系检验发现三类网络成瘾倾向与使用频率都有显著相关．与使用时间都无显著相关。T检验发现女生在网络关系成瘾倾向的依附倾向得分显著高于男生,男生在网络娱乐成瘾倾向和信息搜集成瘾倾向的问题倾向得分显著高于女生。

自我韧性量表与Connor-Davidson韧性量表的应用比较

目的:考察自我韧性量表中文版的心理测量学指标,探讨其与Connor-Davidson韧性量表的关系,比较两者在中国人群中的应用效果。方法:在社区人群中施测自我韧性量表和Connor-Davidson韧性量表的中文版,以及自尊量表、生活满意度指数A问卷、大五人格问卷。结果:自我韧性量表中文版的内部一致性系数为0.77,略低于Connor-Davidson韧性量表。自我韧性量表与Connor-Davidson韧性量表的相关系数为0.61。在以自尊、生活满意度、大五人格为效标时,偏相关分析表明控制了Connor-Davidson韧性量表得分后,自我韧性量表与效标的相关未达到显著水平(除大五人格的外向性维度外);但控制了自我韧性量表得分后,Connor-Davidson量表与效标的相关仍达到显著水平(除开放性维度外)。结论:在我国人群的应用中,Connor-Davidson韧性量表优于自我韧性量表,是值得推广的韧性测量工具。     

Rhyming words and onset-rime constituents: an inquiry into structural breaking points and emergent boundaries in the syllable

Geudens and Sandra, in their 2003 study, investigated the special role of onsets and rimes in Dutch-speaking children's explicit phonological awareness. In the current study, we tapped implicit phonological knowledge using forced-choice similarity judgment (Experiment 1) and recall of syllable lists (Experiment 2). In Experiment 1, Dutch-speaking prereaders judged rime-sharing pseudowords (/fas/-/mas/) to sound more similar than pseudowords sharing an equally sized nonrime unit (/fas/-/fak/). However, in a syllable recall task (/tepsilonf/, /ris/, /nal/), Dutch-speaking prereaders were as likely to produce recombination errors that broke up the rime (/tepsilons/) as to produce errors that retained the rime (/repsilonf/). Thus, a rime effect was obtained in a task that highlighted the phonological similarity between items sharing their rimes, but this effect disappeared in tasks without repetition of rime units. We conclude that children's sensitivity to rimes depends on similarity relations and might not reflect a fixed perceived structure of spoken syllables.     

Subject-Verb Agreement in Children and Adults: Serial or Hierarchical Processing?

Two processes, serial and hierarchical, are generally opposed to account for grammatical encoding in language production. In a developmental perspective, the question addressed here is whether the subject-verb agreement during writing is computed serially, once the words are linearly ordered in the sentence, or hierarchically, as soon as the number features are determined in a hierarchical frame. Adults and children from 3rd to 5th grades were requested to listen to sentences with built-in prepositional phrases or relative clauses and to transcribe them as quickly as possible. A serial hypothesis assumes that subject-verb agreement errors should be equally frequent with both preambles because each has the same length separating the subject head noun and the main verb. Conversely, according to a hierarchical view, errors should be more frequent with a prepositional phrase because the syntactic distance between the subject and the verb is greater than with a relative clause. The results revealed a main effect of the preamble manipulated in 5th graders and adults, but not in 3rd graders. These data were in favor of a hierarchical processing in older writers and a serial one in younger children. However, in 3rd grade, we assumed that the potential serial account was a result of the resource constraint on writing more than of a real serial processing of the agreement.     

Belief in luck and luckiness: Conceptual clarification and new measure validation

Research on the dimensionality and measurement of luck beliefs has yet to produce a clear conceptual and metrical consensus. This research theorizes a bidimensional model of luck beliefs that is tested through a series of studies (total n = 1205) validating the new Belief in Luck and Luckiness Scale. Unlike existing conceptualizations and measures, this new model is applicable to both believers and non-believers in luck, and reveals belief in luck and personal luckiness to be discrete, uncorrelated, and respectively unidimensional constructs.     

The physical activity and sport anxiety scale (PASAS): Scale development and psychometric analysis

Research suggests that social anxiety may be elicited in athletic or sporting situations, resulting in decreased physical activity due to avoidance behavior. Given the myriad physical and psychological health consequences of a non-active lifestyle, valid assessment of social anxiety and avoidance in this domain is warranted. However, none of the common measures of social anxiety appear to assess social anxiety in physical activity or sporting domains. Therefore, the purpose of this study was to develop and evaluate a brief measure of social anxiety in physical activities and sports. A 16-item self-report questionnaire, the Physical Activity and Sport Anxiety Scale (PASAS), was extracted from a larger pool on empirical and theoretical grounds. The PASAS demonstrated excellent internal consistency across a number of samples, and excellent temporal stability. The PASAS also demonstrated good convergent and divergent validity, and is related to self-perceived performance biases as postulated by cognitive-behavioral models of social anxiety.     

Development and initial validation of the Brief Adolescent Life Event Scale (BALES)

We report initial validity analyses of the Brief Adolescent Life Event Scale (BALES). This instrument addresses negative and positive events pertinent to the well being of adolescent boys and girls, and is designed for use in studies utilizing an extended research protocol. Selection of items was guided by emerging perspectives on positive psychology , action theory , and personality vulnerability , as well as by new developments in statistical modeling theory. The 36 items of the scale tap negative and positive events, each of which addresses interpersonal and achievement life domains. Using a large sample of early-adolescents ( N = 895), we confirmed the hypothesized structure that includes four domain-level latent factors (i.e., negative interpersonal events, negative achievement events, positive interpersonal events, positive achievement events), and two overarching factors (negative events and positive events). Indices of positive and negative events predicted adolescent depressive symptoms in expected ways, and positive events buffered the effect of negative events on depressive symptoms. These findings encourage an informed use of the BALES and highlight considerations involved in the development of brief measures of stress and coping processes.     

Associations between miscellaneous symptoms and symptom dimensions in adults with obsessive-compulsive disorder

Abstract

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric condition with a heterogeneous array of obsessions and compulsions. Although factor analytic studies have identified symptom dimensions comprising the clinical presentation of OCD, many frequently reported miscellaneous symptoms are not considered in factor analytic studies because they do not fit conceptually within a particular symptom category, despite being functionally related. In the present study, we examined the associations between miscellaneous symptoms and OCD symptom dimensions in a sample of 111 adults with OCD. Overall, most miscellaneous symptoms were associated with one or more symptom dimensions in previously identified four- (14 of the 22 symptoms) and five-factor models (12 of the 22 symptoms). In both models, Contamination/Cleaning was the only dimension not related to any miscellaneous symptom. The present results provide information about which miscellaneous symptoms may be related to particular symptom dimensions, which will assist in clinical evaluations and help planning behavioral psychotherapy (e.g., hierarchy development).     

Stereotype threat can reduce older adults' memory errors

Stereotype threat often incurs the cost of reducing the amount of information that older adults accurately recall. In the current research, we tested whether stereotype threat can also benefit memory. According to the regulatory focus account of stereotype threat, threat induces a prevention focus in which people become concerned with avoiding errors of commission and are sensitive to the presence or absence of losses within their environment. Because of this, we predicted that stereotype threat might reduce older adults' memory errors. Results were consistent with this prediction. Older adults under stereotype threat had lower intrusion rates during free-recall tests (Experiments 1 and 2). They also reduced their false alarms and adopted more conservative response criteria during a recognition test (Experiment 2). Thus, stereotype threat can decrease older adults' false memories, albeit at the cost of fewer veridical memories, as well.
