Examining the Relation Between Technical and Global Competence in Two Treatments for Youth Anxiety

Although technical (quality of delivering techniques from a specific treatment) and global (general clinical expertise) competence are believed to be important ingredients of successful psychosocial treatment with youth, there have been few empirical efforts to measure both dimensions. Efforts to understand the role that each competence dimension plays in the process and outcome of youth treatment starts with determining whether the dimensions can be measured separately. This study examined whether scores from measures designed to assess technical and global competence were distinct. Treatment sessions (N = 603) from 38 youths (M age = 9.84 years, SD = 1.65; 60.5% White; 52.6% male) treated for primary anxiety problems within a randomized effectiveness trial were coded. Four coders used observational measures designed to assess technical competence, global competence, protocol adherence, and the alliance. Mean item interrater reliability was .70 (SD = .09) for technical competence and .66 (SD = .05) for global competence. While most components of global competence were distinct from technical competence scores, two components showed redundancy (r > .70). Scores on both competence measures were empirically distinct (r < .70) from scores on measures of protocol adherence and the alliance. Although the measures did not fully distinguish between technical and global competence, our findings do indicate that some components of technical and global competence may provide unique information about competence.     

在什么情况下员工会汇报差错?基于秘密分享视角

差错在工作场所中并不鲜见, 然而有关差错诊断的研究相对匮乏。基于此, 以员工主动差错汇报为切入点, 分析影响员工差错汇报的因素。结合秘密分享框架, 提出差错特点(差错严重性与可见性)对员工的焦虑感、反刍和汇报责任感产生正向影响; 而焦虑感、反刍和汇报责任感会促使员工采取差错汇报行为, 由此上述个体感知中介差错特点与差错汇报之间的关系; 此外, 个体责任心、领导容错性以及团队心理安全会作为边界条件进一步影响上述员工犯错后的感知, 并最终影响其差错汇报行为。     

Monothematic delusion: A case of innocence from experience

Empiricists about monothematic delusion formation agree that anomalous experience is a factor in the formation of these attitudes, but disagree markedly on which further factors (if any) need to be specified. I argue that epistemic innocence may be a unifying feature of monothematic delusions, insofar as a judgment of epistemic innocence to this class of attitudes is one that opposing empiricist accounts can make. The notion of epistemic innocence allows us to tell a richer story when investigating the epistemic status of monothematic delusions, one which resists the trade-off view of pragmatic benefits and epistemic costs. Though monothematic delusions are often characterized by appeal to their epistemic costs, they can play a positive epistemic role, and this is a surprising conclusion on which, so I argue, all empiricists can agree. Thus, I show that all empiricists have the notion of epistemic innocence at their disposal.     

Bilateral Transfer in Tapping Skill in the Absence of Peripheral Information

Bilateral transfer in a fast tapping task was investigated under normal (+FB) and reduced (-FB) feedback conditions, in the -FB experiment 36 Ss were assigned to 3 groups: preferred (PH) to non-preferred (NPH) shift; NPH to PH; and alternating trials of PH and NPH. With + FB 2 further groups of 12 Ss transferred PH to NPH or NPH to PH. 8 preshift and 8 postshift trials were given. The alternating group had 8 PH and 8 NPH trials. In preshift performance increment was found in ail groups except in +FB with NPH. With +FB some facilitation in transfer was obtained for the NPH; under -FB marked positive transfer was found for the PH. Alternating PH and NPH performance conformed to preshift levels. Results were discussed in terms of differential central control processes for the two hands.     

Coalitional Capacities and Environmental Strategies to Prevent Underage Drinking

Coalitions are the most common platform for implementing community-level environmental strategies (ES), such as media, policy, or enforcement for substance use prevention. The current study examines the associations between two types of coalition capacity (general and innovation-specific) and ES implementation efforts and outputs within 14 intervention communities over a three-year period. Efforts refer to the amount of energy exerted to implement an ES while outputs refer to the materials produced through these efforts. Quantitative measures of capacity were provided by coalition key informants and expert-raters. Additionally, Training and Technical Assistance (TTA) provided proactively to improve the implementation of ES was also examined. Greater general capacity, as rated by a coalition informant, was associated with more ES policy effort. Both expert-rated general and innovation-specific capacity, however, were associated with greater ES outputs. Study results also found that community coalitions that endorsed weaker mobilization, structure and task leadership, (measures of general capacity), utilized more TTA compared to those who perceived their coalition as having greater capacity. Moreover, communities that utilized more TTA resources reported a greater number of successful policy changes. The study supports the need to consider both general and innovation-specific capacity for ES implementation and offers promising preliminary findings regarding the role of TTA for improving coalitions’ capacity to facilitate policy change.     

Statistical Significance Levels of Nonparametric Tests Biased by Heterogeneous Variances of Treatment Groups

The statistical significance levels of the Wilcoxon-Mann-Whitney test and the Kruskal-Wallis test are substantially biased by heterogeneous variances of treatment groups—even when sample sizes are equal. Under these conditions, the Type I error probabilities of the nonparametric tests, performed at the .01, .05, and .10 significance levels, increase by as much as 40%-50% in many cases and sometimes as much as 300%. The bias increases systematically as the ratio of standard deviations of treatment groups increases and remains fairly constant for various sample sizes. There is no indication that Type I error probabilities approach the significance level asymptotically as sample size increases.     

How Do Propensity Score Methods Measure Up in the Presence of Measurement Error? A Monte Carlo Study

Considering that the absence of measurement error in research is a rare phenomenon and its effects can be dramatic, we examine the impact of measurement error on propensity score (PS) analysis used to minimize selection bias in behavioral and social observational studies. A Monte Carlo study was conducted to explore the effects of measurement error on the treatment effect and balance estimates in PS analysis across seven different PS conditioning methods. In general, the results indicate that even low levels of measurement error in the covariates lead to substantial bias in estimates of treatment effects and concomitant reduction in confidence interval coverage across all methods of conditioning on the PS.     

The impact of error frequency on errorless and errorful learning of object locations using a novel paradigm

ABSTRACT

Errorless learning (EL) is an approach in which errors are eliminated or reduced as much as possible while learning of new information or skills. In contrast, during trial-and-error???or errorful???learning (TEL) errors are not reduced and are often even promoted. There is a complex and conflicting pattern of evidence whether EL or TEL may result in better memory performance. One major confound in the extant literature is that most EL studies have not controlled for the number of errors made during TEL, resulting in a large variability in the amount of errors committed. This variability likely explains why studies on the cognitive underpinnings of EL and TEL have produced mixed findings. In this study, a novel object-location learning task was employed to examine EL and TEL in 30 healthy young adults. The number of errors was systematically manipulated, allowing us to investigate the impact of frequency of errors on learning outcome. The results showed that recall from memory was significantly better during EL. However, the number of errors made during TEL did not influence the performance in young adults. Altogether, our novel paradigm is promising for measuring EL and TEL, allowing for more accurate analyses to understand the impact of error frequency on a person’s learning ability and style.
