The true intra‐individual change model is generalized by defining individual method effects. This allows the analysis of non‐congeneric test–retest variables assumed to measure a common, possibly (temporally) transient, attribute. Temporal change in the attribute between different times of measurement is modelled by the true‐change variable. Individual causal method effects, due to heterogeneity of the measurement methods, account for the imperfect correlation of the true‐score variables at each time of measurement. The reliability of the composite scores, at each time of measurement, and the reliability of the difference composite score may be estimated with appropriate coefficients derived from the model. Measurements of daily life tension in adult females serve to illustrate how the model can be used empirically. 相似文献

In two experiments, we used response signals (RSs) to control processing time and trace out speed--accuracy trade-off(SAT) functions in a difficult perceptual discrimination task. Each experiment compared performance in blocks of trials with constant and, hence, temporally predictable RS lags against performance in blocks with variable, unpredictable RS lags. In both experiments, essentially equivalent SAT functions were observed with constant and variable RS lags. We conclude that there is little effect of advance preparation for a given processing time, suggesting that the discrimination mechanisms underlying SAT functions are driven solely by bottom-up information processing in perceptual discrimination tasks. 相似文献

The study compared patient experiences with psychiatric treatment provided by private practitioners and public outpatient clinics. Questionnaires were completed by 642 outpatients in private practice and 6,677 outpatients in public clinics. The questionnaire included a measure of patient experiences comprising six items: treatment outcome, enough time for contact and dialogue with clinician, clinicians' understanding of patient's situation, suitability of therapy and treatment, clinician follow-up of planned actions, and influence on treatment. Patients in private practice had generally better experiences than patients in public outpatient treatment. The difference between private and public patients was largest for patients with poor self-evaluated mental health or those who had just one consultation in the previous three months. Private practitioners appear to have an important role in mental health services delivery, and patients have relatively good experiences with services. Further studies that assess the patient - clinician interaction in different mental health services may give further insights into potential service improvements. 相似文献

Trajectories of Delinquency and Parenting Styles 总被引:3,自引:2,他引:1

We investigated trajectories of adolescent delinquent development using data from the Pittsburgh Youth Study and examined the extent to which these different trajectories are differentially predicted by childhood parenting styles. Based on self-reported and official delinquency seriousness, covering ages 10-19, we identified five distinct delinquency trajectories differing in both level and change in seriousness over time: a nondelinquent, minor persisting, moderate desisting, serious persisting, and serious desisting trajectory. More serious delinquents tended to more frequently engage in delinquency, and to report a higher proportion of theft. Proportionally, serious persistent delinquents were the most violent of all trajectory groups. Using cluster analysis we identified three parenting styles: authoritative, authoritarian (moderately supportive), and neglectful (punishing). Controlling for demographic characteristics and childhood delinquency, neglectful parenting was more frequent in moderate desisters, serious persisters, and serious desisters, suggesting that parenting styles differentiate non- or minor delinquents from more serious delinquents. 相似文献

Relatively little is known about the factor structure of disruptive behavior among preadolescent girls. The present study
reports on exploratory and confirmatory factor analyses of disruptive girl behavior over four successive data waves as rated
by parents and teachers in a large, representative community sample of girls (N = 2,451). Five factors were identified from parent ratings (oppositional behavior/conduct problems, inattention, hyperactivity/impulsivity,
relational aggression, and callous-unemotional behaviors), and four factors were identified derived from teacher ratings (oppositional
behavior/conduct problems/callous-unemotional behaviors, inattention, hyperactivityimpulsivity, and relational aggression).
There was a high degree of consistency of items loading on equivalent factors across parent and teacher ratings. Year-to-year
stability of factors between ages five and 12 was high for parent ratings (ICC = 0.70 to 0.88), and slightly lower for teacher
ratings (ICC = 0.56 to 0.83). These findings are discussed in terms of possible adjustment to the criteria for children's
disruptive behavior disorders found in the Diagnostic and Statistical Manual for Mental Disorders.

In this very private account about my psychoanalytic career I draw some consequences concerning the long and widely discussed questions of the setting. Especially, I refer to my many years of experience I was able to gain in the framework of focal conferences. 相似文献

We examined sequential effects in the variable foreperiod (FP) paradigm, which refer to the finding that responses to an imperative signal (IS) are fast when a short FP trial is repeated but slow when it is preceded by a long FP trial. The effect has been attributed to a trace-conditioning mechanism in which individuals learn the temporal relationship between a warning signal (WS) and the IS in a trial-by-trial manner. An important assumption is that the WS in a current trial (i.e., trial FPn) acts as a conditioned stimulus, such that it automatically triggers the conditioned response at the exact critical moment that was imperative in the previous trial (i.e., trial FPn−1). According to this assumption, a shift from one WS modality in trial FPn−1 to another modality in trial FPn is expected to eliminate or at least reduce the sequential FP effect. This prediction was tested in three experiments that included a random variation of WS modality and FP length within blocks of trials. In agreement with the prediction, a shift in WS modality attenuated the asymmetry of the sequential FP effect. 相似文献

Argumentation in the sense of a process of logical reasoning is a very intuitive and general methodology of establishing conclusions from defeasible premises. The core of any argumentative process is the systematical elaboration, exhibition, and weighting of possible arguments and counter-arguments. This paper presents the formal theory of probabilistic argumentation, which is conceived to deal with uncertain premises for which respective probabilities are known. With respect to possible arguments and counter-arguments of a hypothesis, this leads to probabilistic weights in the first place, and finally to an overall probabilistic judgment of the uncertain proposition in question. The resulting probabilistic measure is called degree of support and possesses the desired properties of non-monotonicity and non-additivity. Reasoning according to the proposed formalism is an simple and natural generalization of the two classical forms of probabilistic and logical reasoning, in which the two traditional questions of the probability and the logical deducibility of a hypothesis are replaced by the more general question of the probability of a hypothesis being logically deducible from the available knowledge base. From this perspective, probabilistic argumentation also contributes to the emerging area of probabilistic logics. 相似文献

We developed the German Adaptation of the Personality Assessment Inventory (PAI; Morey, 1991) under careful consideration of current adaptation literature and guidelines. The adaptation process included the translation of the 344 items into German, a back translation into English as well as the testing of the language equivalence using a bilingual sample. We then standardized the final German version of the PAI for the German population. We compared the American and German norm and reliability data. The observed differences in PAI scale means did not exceed 5 T scores. Internal consistency reliability showed a similar pattern in both language versions, although the German alpha coefficients were on average slightly lower than the American ones. Factor structure was similar in both versions. We discuss expectations about the German PAI and possible problems for its practical usefulness for the German-speaking population. 相似文献
