Building a Theoretical Model for Supporting Teens’ Autonomy Daily (STAND): A Network Analysis of Family-Perceived Changes

Little is known about processes through which behavior therapy (BT) for adolescent ADHD improves outcomes. The purpose of this study was to build a theoretical model for the processes through which a BT for adolescent ADHD (Supporting Teens’ Autonomy Daily; STAND) impacts functioning. Seventy-eight audio recordings from a standard therapeutic task in the final STAND session were analyzed as parents and adolescents (ages 11–16) reflected upon what changed during STAND and why. Qualitative coding sorted parent and teen statements into orthogonal categories of perceived changes. Network analysis examined inter-relations between categories. Results indicated twenty-one categories of perceived change areas. Parent use of behavioral strategies, adolescent motivation, and adolescent organization skills were central nodes in the network of perceived changes, with strong relations to academic and parent-teen relationship outcomes. A model is proposed in which skills training in STAND increases parent behavioral strategy use and teen organization skills, while Motivational Interviewing (MI) in STAND increase parent behavioral strategy use and initial adolescent motivation. In turn, parent behavioral strategy use is proposed to further reinforce teen motivation through contingency management, thereby increasing teen application of organization skills to daily life. As a result of improved teen motivation and organization skills, the model proposes that ADHD symptoms, academic problems, and parent-teen conflict abate. We discuss secondary mechanisms and outcomes in this model, the possibility of person-specific processes, implications for community-based adaptation of STAND, and plans to validate this conceptual model using sophisticated mediational models.     

Pain and Bodily Care: Whose Body Matters?

Pain is unpleasant. It is something that one avoids as much as possible. One might then claim that one wants to avoid pain because one cares about one's body. On this view, individuals who do not experience pain as unpleasant and to be avoided, like patients with pain asymbolia, do not care about their body. This conception of pain has been recently defended by Bain [2014 Bain, D. 2014. Pains That Don't Hurt, Australasian Journal of Philosophy 92/2: 305–20.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]] and Klein [forthcoming Klein, C. forthcoming. What Pain Asymbolia Really Shows, Mind. [Google Scholar]]. In their view, one needs to care about one's body for pain to have motivational force. But does one need to care about one's body qua one's own? Or does one merely need to care about the body that happens to be one's own? In this paper, I will consider various interpretations of the notion of bodily care, in light of a series of pathological cases in which patients report pain in a body part that they do not experience as their own. These cases are problematic if one adopts a first-personal interpretation of bodily care, according to which pain requires one to care about what is represented as one's own body. The objection can run as follows. If the patients experience the body part as alien, then they should not care about it. Therefore, they should be similar to patients with pain asymbolia. But they are not. Hence, bodily care is not necessary to pain. To resist this conclusion, one can try to revise the interpretation of the notion of bodily care and to offer alternative interpretations that are not first-personal. However, I will show that that those alternatives also fail to account for these borderline cases of pain.     

On the distinction between open and closed economies.

Open and closed economies have been assumed to produce opposite relations between responding and the programmed density of reward (the amount of reward divided by its cost). Experimental procedures that are treated as open economies typically dissociate responding and total reward by providing supplemental income outside the experimental session; procedures construed as closed economies do not. In an open economy responding is assumed to be directly related to reward density, whereas in a closed economy responding is assumed to be inversely related to reward density. In contrast to this predicted correlation between response-reward relations and type of economy, behavior regulation theory predicts both direct and inverse relations in both open and closed economies. Specifically, responding should be a bitonic function of reward density regardless of the type of economy and is dependent only on the ratio of the schedule terms rather than on their absolute size. These predictions were tested by four experiments in which pigeons' key pecking produced food on fixed-ratio and variable-interval schedules over a range of reward magnitudes and under several open- and closed-economy procedures. The results better supported the behavior regulation view by showing a general bitonic function between key pecking and food density in all conditions. In most cases, the absolute size of the schedule requirement and the magnitude of reward had no effect; equal ratios of these terms produced approximately equal responding.     

Some properties of the correlation matrix of dichotomous guttman items

Both the elements and the eigenvalues of the Pearson correlation matrix of dichotomous Guttman-scalable items can be expressed as simple functions of the number of items if the score distribution is uniform and there is an equal number of items at each difficulty level. Even when these special conditions do not hold, the correlations can often be expressed in a simple form by assuming a particular score distribution.The author thanks Neil Dorans, Bob Mislevy, Ledyard R Tucker, and Howard Wainer for their comments.

尿沉渣法、干化学法及传统镜检测定尿液中有形成分的对比研究

以传统镜检法结果作为标准,分别采用AX4280全自动尿液干化学法分析仪（干化学法）和IQ200尿沉渣分析仪（尿沉渣法）及两种方法的并联和串联检测新疆石河子地区532例患者的清洁中段尿,并评价两种方法的检测效果。结果显示,与传统镜检法比较,干化学法和尿沉渣法串联对尿液中红、白细胞检出率的阳性预测值高,具有临床意义;尿沉渣法对红、白细胞检测误诊率较高,需用镜检进行确认。尿沉渣法和干化学法可对临床提供一定的依据,但不能完全代替传统镜检,几种方法可作为互补,提高检测准确性。
