Measurement Error-Corrected Estimation of Clinically Significant Change Trajectories for Interventions Targeting Comorbid PTSD and Substance Use Disorders in OEF/OIF Veterans

In randomized control trials (RCTs), a focus on average differences between treatment arms often limits our understanding of whether individuals show clinically significant improvement or deterioration. The present study examined differences in individual-level clinical significance trajectories between Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE) and Relapse Prevention (RP). Eighty-one treatment-seeking veterans with a comorbid PTSD/SUD diagnosis were randomized to COPE or RP; data from an additional n = 48 patients who did not meet criteria for both disorders was used to establish a normative threshold. A newly developed, modernized approach to the Jacobson and Truax (1991) clinically significant change framework, using (a) moderated nonlinear factor analysis (MNLFA) scale scoring and (b) measurement error-corrected multilevel modeling (MEC-MLM) was used; this approach was compared to other approaches using conventional total scores and/or assuming no measurement error. Using a conventional approach to estimating the Reliable Change Index (RCI) yielded no differences between COPE and RP in the percentage of patients achieving statistically significant improvement (SSI; 88.9% for both groups). However, under MNLFA/MEC-MLM, higher percentages of patients receiving COPE (75.0%) achieved SSI compared to RP (40.7%). Findings suggest that, even though COPE and RP appear to reduce the same number of PTSD symptoms, MNLFA scoring of outcome measures gives greater weight to interventions that target and reduce “hallmark” PTSD symptoms.     

中国文化下组织政治技能对个体自身的影响作用

组织政治技能是个体在组织中生存和获得职业发展的重要能力之一,也是组织行为学研究中的重要领域。研究主要从中国文化的视角,探讨组织政治技能对个体自身的影响作用。结果显示,组织政治技能与工作满意度之间存在线性关系,而非曲线关系;组织政治技能中的处世圆通和面子和谐两个维度有利于缓解工作压力,而人际敏锐可能增加个体的工作压力感;自我评价对于组织政治技能与工作压力和工作满意度之间关系的中介效应不显著;工作压力在处世圆通、人际敏锐和面子和谐三个维度与工作满意度之间起完全中介作用。这些结果表明,组织政治技能对于个体来说是非常重要的能力,可以帮助个体缓解工作压力,提高工作满意感,进而促进个体的职业发展。     

The Effect of Psychological Skills Training (PST) on Self-Regulation Behavior,Self-Efficacy,and Psychological Skill Use in Military Pilot-Trainees

From pre- to post-intervention, findings showed that specific self-regulation behavior increased linearly. Likewise, significant increases in self-efficacy and psychological skill use occurred, along with concomitant reductions in anxiety and worry. Changes were generally retained at 2-month follow-up. PST highlights potential in modifying pilot-trainee cognitive and behavioral strategies to underpin learning, improve individual/cohort responsiveness, and importantly, cost effectiveness in training provision.

Training Motor Sequences: Effects of Speed and Accuracy Instructions

Participants practiced a fixed 3- and a fixed 6-key press sequence for 144 times each. In the speed group, they were instructed to execute their sequences fast without bothering much about errors while the accurate group was instructed to be careful and prevent errors. In the test phase, participants executed series of 3 and 6 responses (a) when all element-specific stimuli were displayed in the familiar order, (b) in response to just the familiar first stimulus, and (c) by responding to random stimuli. The speed instruction yielded stronger sequencing skill while the accuracy instruction developed stronger reaction skill.     

Emotion in man as Tested by the Delta Index of the Electroencephalogram: II. Simultaneous Records from Cortex and from a Region Near the Hypothalamus

Five male undergraduates could earn 4¢ for every 200 knob-pulls. In addition, they could avoid or terminate an aversive tone by pressing a button with a force of 1.5 lbs (nonaggressive response) or by hitting a cushion with at least 20 lbs force (aggressive response). Rates of aggression tended to be higher during sessions where money was taken from the Ss at the rate of 1¢ per 12 seconds than during sessions when taking was not in effect. Rates of nonaggressive responses were constant across conditions.     

The Coding of Location

One prediction of the recent target hypothesis for movement control (MacNeilage, 1970; Russell, 1976) holds that location reproduction is not solely dependent upon stored kinesthetic information. Three experiments were performed to test this prediction by requiring the subject to reproduce the location with the limb opposite to the one used for criterion production. This switched-limb procedure was assumed to force the subject to rely upon more abstract information rather than the kinesthetic cues of the criterion movement. With movement direction invariant, switched-limb reproduction was equal to same-limb reproduction. The alteration of movement direction hampered switched-limb reproduction but same-limb reproduction was not greatly affected. These findings gave some support to the target hypothesis but suggested that the context of the movement may affect the potency of the location code. Implications of the switched-limb technique for future research were briefly discussed.     

Acquisition and Automatization of a Complex Task: An Examination of Three-Ball Cascade Juggling

The learning patterns of 3-ball cascade juggling from acquisition until automaticity were examined in 10 participants. On the basis of outcome measures derived from 26 practice sessions and 4 periodic probe sessions, the authors differentiated participants into 3 distinct learning types: a proficient group, an emerging group, and a single late learner. The proficient group was distinguished by how rapidly they learned and automatized performance. Most interesting, an inverse response cost (i.e., performance boost) on the secondary task was found in the majority of proficient group members during the dual-task condition. The present results are discussed in relation to the P. L. Ackerman model (1987, 1988) of complex skill acquisition as is the significance of the inverse response cost finding.     

Visual and Proprioceptive Determinants of Space Perception and Movement

The present study determined the relationship between perception of the upright in 2-dimensional space and movement accuracy. 161 female Ss were administered the Rod and Frame Test, and 30 Ss, whose scores indicated the greatest and least error in perceptual differentiation, were assigned to 2 experimental groups and measured on accuracy of postural pursuit tracking. The effects of direction of movement and visual field conditions on accuracy of performance were determined by a coordinate postural platform and hybrid computer methods. A direct relationship existed between perception of the vertical in space and accuracy of motor responses and that perceptual integration was affected by the direction of movement and the presence of a stable visual field.
