We discuss the statistical testing of three relevant hypotheses involving Cronbach's alpha: one where alpha equals a particular criterion; a second testing the equality of two alpha coefficients for independent samples; and a third testing the equality of two alpha coefficients for dependent samples. For each of these hypotheses, various statistical tests have been proposed. Over the years, these tests have depended on progressively fewer assumptions. We propose a new approach to testing the three hypotheses that relies on even fewer assumptions, is especially suited for discrete item scores, and can be applied easily to tests containing large numbers of items. The new approach uses marginal modelling. We compared the Type I error rate and the power of the marginal modelling approach to several of the available tests in a simulation study using realistic conditions. We found that the marginal modelling approach had the most accurate Type I error rates, whereas the power was similar across the statistical tests. 相似文献

Although parents experience growing concerns about their children’s excessive internet use, little is known about the role
parents can play to prevent their children from developing Compulsive Internet Use (CIU). The present study addresses associations
between internet-specific parenting practices and CIU among adolescents, as well as the bidirectionality of these associations.
Two studies were conducted: a cross-sectional study using a representative sample of 4,483 Dutch students and a longitudinal
study using a self-selected sample of 510 Dutch adolescents. Results suggest that qualitatively good communication regarding
internet use is a promising tool for parents to prevent their teenage children from developing CIU. Besides, parental reactions
to excessive internet use and parental rules regarding the content of internet use may help prevent CIU. Strict rules about
time of internet use, however, may promote compulsive tendencies. Finally, one opposite link was found whereby CIU predicted
a decrease in frequency of parental communication regarding internet use. 相似文献

The development of three aspects of selective attention was studied in 451 Dutch schoolchildren attending second to sixth grade. Selective attention was measured with the d2 Test of attention. The largest age differences were found for processing speed that continued to improve until the sixth grade. Impulsivity, as measured by the percentage of errors of commission, decreased until the fourth grade. Inattention, measured by the percentage of errors of omission, was stable in all grades. Processing speed and impulsivity were correlated with the score on the Attention Problems subscale of the Child Behavior Checklist. These results imply that selective attention continues to develop, at least, until the end of elementary school. The findings are support for a step-wise model of cognitive development (P. Anderson, 2002). 相似文献

The present study investigated the relationships between adolescents' online communication and compulsive Internet use, depression, and loneliness. The study had a 2-wave longitudinal design with an interval of 6 months. The sample consisted of 663 students, 318 male and 345 female, ages 12 to 15 years. Questionnaires were administered in a classroom setting. The results showed that instant messenger use and chatting in chat rooms were positively related to compulsive Internet use 6 months later. Moreover, in agreement with the well-known HomeNet study (R. Kraut et al., 1998), instant messenger use was positively associated with depression 6 months later. Finally, loneliness was negatively related to instant messenger use 6 months later. 相似文献

Earlier studies provided preliminary support for the role of classical conditioning as a pathway of disgust learning, yet this evidence has been limited to self-report. This study included facial electromyographical (EMG) measurements (corrugator and levator muscles) and a behavioural approach task to assess participants’ motivation-to-eat the actual food items (conditioned stimuli, CS). Food items served as CS and film excerpts of a woman vomiting served as unconditioned stimuli (US). Following acquisition the CS+ (neutral CS paired with US disgust) was rated as more disgusting and less positive. Notably, the conditioned response was transferred to the actual food items as evidenced by participants’ reported lowered willingness-to-eat. Participants also showed heightened EMG activity in response to the CS+ which seemed driven by the corrugator indexing a global negative affect. These findings suggest that classical conditioning as a pathway of disgust learning can be reliably observed in subjective but not in disgust-specific physiological responding. 相似文献

Evaluation of the 113Online Suicide Prevention Crisis Chat Service: Outcomes,Helper Behaviors and Comparison to Telephone Hotlines 下载免费PDF全文
Jan K. Mokkenstorm MD Merijn Eikelenboom LLM Annemiek Huisman PhD Jasper Wiebenga MSc Renske Gilissen PhD Ad J. F. M. Kerkhof PhD Johannes H. Smit PhD 《Suicide & life-threatening behavior》2017,47(3):282-296
Recognizing the importance of digital communication, major suicide prevention helplines have started offering crisis intervention by chat. To date there is little evidence supporting the effectiveness of crisis chat services. To evaluate the reach and outcomes of the 113Online volunteer‐operated crisis chat service, 526 crisis chat logs were studied, replicating the use of measures that were developed to study telephone crisis calls. Reaching a relatively young population of predominantly females with severe suicidality and (mental) health problems, chat outcomes for this group were found to be comparable to those found for crisis calls to U.S. Lifeline Centers in 2003–2004, with similar but not identical associations with specific helpers' styles and attitudes. Our findings support a positive effect of the 113Online chat service, to be enhanced by practice standards addressing an apparent lack of focus on the central issue of suicidality during chats, as well as by the development of best practices specific for online crisis intervention. 相似文献

The transition to adolescence marks a time of sharply increased vulnerability to the development of depression, particularly
among girls. Past research has examined isolated risk factors from individual theoretical models (e.g., biological, interpersonal,
and cognitive) of depression, but few have examined integrative models. This study investigated the conjoint effects of early
pubertal timing and popularity in the longitudinal prediction of depressive symptoms. A total of 319 girls and 294 boys (ages
11–14) provided information on their pubertal status, depressive symptoms, and the social status (i.e., popularity) of their
peers. Adolescents completed a second measure of depressive symptoms 11 months after the initial time point. Findings supported
an integrated biological-interpersonal model in explaining the development of depressive symptoms during adolescence. Early
pubertal development was associated with increase in depressive symptoms only when accompanied by low levels of popularity.
High levels of popularity buffered the association between early pubertal development and later depressive symptoms. Unexpectedly,
these results were significant both for girls and boys. Results are discussed in terms of dynamic systems theories. 相似文献

This study examines inter-individual differences in how presentation modality affects verbal learning performance. Children aged 5 to 16 performed a verbal learning test within one of three presentation modalities: pictorial, auditory, or textual. The results indicated that a beneficial effect of pictures exists over auditory and textual presentation modalities and that this effect increases with age. However, this effect is only found if the information to be learned is presented once (or at most twice) and only in children above the age of 7. The results may be explained in terms of single or dual coding of information in which the phonological loop is involved. Development of the (sub)vocal rehearsal system in the phonological loop is believed to be a gradual process that begins developing around the age of 7. The developmental trajectories are similar for boys and girls. Additionally, auditory information and textual information both seemed to be processed in a similar manner, namely without labeling or recoding, leading to single coding. In contrast, pictures are assumed to be processed by the dual coding of both the visual information and a (verbal) labeling of the pictures. 相似文献

In general, attitudes towards nations have a fair amount of reciprocity: nations either like each other, are relatively indifferent to each other, or dislike each other. Sometimes, however, international attitudes are asymmetrical. In this study, we use social identity theory in order to explain asymmetrical attitudes. Parting from social identity theory, asymmetrical attitudes can be predicted to occur most likely between countries that are linguistically either similar or closely related, but differ in size. Europe, more than any other continent, offers a rich variety of nations which represent natural conditions for our study, such as size and degree of linguistic similarity. In order to test hypotheses derived from social identity theory, we asked respondents (N = 405) from (Dutch‐ and French‐speaking) Belgium, France, Germany, and The Netherlands to fill out a questionnaire on three large nations (Germany, Great Britain, France) and three smaller ones (The Netherlands, Belgium, and Denmark). Results strongly supported hypotheses and confirm that a social identity approach may help to better understand international attitudes. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献
