Effectiveness of Cognitive Behavior Therapy for Severe Mood Disorders in an Acute Psychiatric Naturalistic Setting: A Benchmarking Study

The current study examined the effectiveness of brief cognitive behavior therapy (CBT) for severe mood disorders in an acute naturalistic setting. The sample included 951 individuals with either major depressive disorder (n = 857) or bipolar disorder with depressed mood (n = 94). Participants completed a battery of self-report measures assessing depression, overall well-being, and a range of secondary outcomes both before and after treatment. We found significant reductions in depressive symptoms, worry, self-harm, emotional lability, and substance abuse, as well as significant improvements in well-being and interpersonal relationships, post-treatment. Comparable to outpatient studies, 30% of the sample evidenced recovery from depression. Comparison of findings to benchmark studies indicated that, although the current sample started treatment with severe depressive symptoms and were in treatment for average of only 10 days, the overall magnitude of symptom improvement was similar to that of randomized controlled trials. Limitations of the study include a lack of control group, a limitation of most naturalistic studies. These findings indicate that interventions developed in controlled research settings on the efficacy of CBT can be transported to naturalistic, “real world” settings, and that brief CBT delivered in a partial hospital program is effective for many patients with severe depressive symptoms.     

Contextual Interference in Movements of the Same Class: Differential Effects on Program and Parameter Learning

Contextual interference effects in motor learning usually were not found when the tasks to be learned presumably required the same generalized motor program (GMP) and differed only with regard to the movement parameters (see Lee, Wulf, & Schmidt, 1992; Magill & Hall, 1990). Thus, tasks requiring different motor programs (e.g., different relative timings) seemed to be a prerequisite for random practice to be more effective than blocked practice. However, the previous studies (that did not find random/blocked differences) used global error measures that confounded errors in relative timing and errors in absolute timing. In the present study, subjects practiced three movement patterns that had the same relative timing (requiring the same GMP) but different overall durations (requiring different parameters). Errors in relative timing and in absolute timing were assessed separately. The results indicate that random practice is more effective for the learning of relative timing (GMP learning) and less effective for the learning of absolute timing (parameter learning) than blocked practice. Preliminary ideas as to the reasons for this effect are discussed.     

Immediate and Latent Interlimb Transfer of Gait Stability Adaptation Following Repeated Exposure to Slips

The authors trained 21 participants by using blocked-and-mixed exposure to right-side slips and then caused them to slip unexpectedly on the untrained left side. Authors retested participants with a right slip and a left slip at 1 week, 2 weeks, 1 month, and 4 months. The authors found that preslip stability on the first untrained left slip improved and was significantly greater than that on the first right slip, which probably contributed to the reduction in incidence of falls from ~30% to ~10%. Postslip stability and base of support (BOS) slip velocity were similar to those on the first right slip and much lower than those on the last right slip. Increases in pre- and postslip stabilities and BOS slip velocity during the left slip led to reductions in backward balance loss (BLOB) from ~95% on initial left slip to ~60% and to ~25% on the 1st and 3rd retest sessions, respectively. In contrast, BLOB remained at a constant ~40% level on the right slip of the same retest sessions. The results indicate a partial immediate transfer and a possible latent transfer.     

Visually guided catching and tracking skills in pigeons: A preliminary analysis

Research on reaching, tracking, and catching in the pigeon has been hampered by limitations of technology. A new system was developed in which the target was a small rectangle presented on a video display terminal and the pecking response was detected with touch technology. The target moved up and down vertically with sinusoidal velocity. A coincidence between the location of the pigeon's beak and the cursor produced reinforcement. The pigeon pecked ahead and behind the target, but most pecks occurred behind the target so the dominant tracking strategy was lagging. The pigeon was adept at “catching” the target at many locations throughout the trajectory. Transfer of motor learning was tested on probe trials during which the trajectory changed from vertical to horizontal. On transfer trials the pigeons' dominant pattern of pecking immediately shifted from vertical to horizontal. The motor skill displayed by the pigeons was flexible and adaptive, suggesting that the pigeons had learned to track the cursor.     

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.     

A Sensemaking Approach to Ethics Training for Scientists: Preliminary Evidence of Training Effectiveness

In recent years, we have seen a new concern with ethics training for research and development professionals. Although ethics training has become more common, the effectiveness of the training being provided is open to question. In the present effort, a new ethics training course was developed that stresses the importance of the strategies people apply to make sense of ethical problems. The effectiveness of this training was assessed in a sample of 59 doctoral students working in the biological and social sciences using a pre–post design with follow-up and a series of ethical decision-making measures serving as the outcome variable. Results showed not only that this training led to sizable gains in ethical decision making but also that these gains were maintained over time. The implications of these findings for ethics training in the sciences are discussed.     

The Effect of Load on Torques in Point-to-Point Arm Movements: A 3D Model

A dynamic, 3-dimensional model was developed to simulate slightly restricted (pronation-supination was not allowed) point-to-point movements of the upper limb under different external loads, which were modeled using 3 objects of distinct masses held in the hand. The model considered structural and biomechanical properties of the arm and measured coordinates of joint positions. The model predicted muscle torques generated by muscles and needed to produce the measured rotations in the shoulder and elbow joints. The effect of different object masses on torque profiles, magnitudes, and directions were studied. Correlation analysis has shown that torque profiles in the shoulder and elbow joints are load invariant. The shape of the torque magnitude-time curve is load invariant but it is scaled with the mass of the load. Objects with larger masses are associated with a lower deflection of the elbow torque with respect to the sagittal plane. Torque direction–time curve is load invariant scaled with the mass of the load. The authors propose that the load invariance of the torque magnitude–time curve and torque direction–time curve holds for object transporting arm movements not restricted to a plane.

Structuring of Early Reaching Movements: A Longitudinal Study

Reaches, performed by 5 infants, recorded at 19 weeks of age and every third week thereafter until 31 weeks of age, were studied quantitatively. Earlier findings about action units were confirmed. At all ages studied, movements were structured into phases of acceleration and deceleration. Reaching trajectories were found to be relatively straight within these units and to change direction between them. It was also found that at all ages, there was generally one dominating transport unit in each reach. The structuring of reaching movements changed in four important ways during the period studied. First, the sequential structuring became more systematic with age, with the dominating transport unit beginning the movement. Second, the duration of the transport unit became longer and covered a larger proportion of the approach. Third, the number of action units decreased with age, approaching the two-phase structure of adult reaching. Finally, reaching trajectories became straighter with age.

From Resistance to Buy-In: Experiences of Clinicians in Training Using Feedback-Informed Treatment

In this qualitative research study, the authors use grounded theory analysis to examine the experiences of clinicians in training and use client feedback to inform treatment. Twenty-six marriage and family therapy graduate students in their first or second semester of clinical practicum participated in this study. Participants were trained in eliciting and responding to client feedback at the end of every therapy session. At the end of the semester, participants reflected on their learning experience. Participant experiences reflected a developmental learning process beginning with significant challenges followed by positive clinical changes and positive clinician changes, culminating in overall buy-in regarding the importance of client feedback for nearly all clinicians. The results support the literature that client feedback directly informs the therapeutic process while suggesting important recommendations for training new clinicians in learning to use client feedback.     

A Family Systems Approach to Behavioral Training with Parents of Autistic Children

This paper reviews briefly the use of behavioral procedures and parent training techniques with parents of autistic children. Potential hazards that may arise when the clinician fails to be sensitive to the family context are examined. Behavioral clinicians are urged to undertake behavioral parent training from a family systems context and thereby enhance the likelihood of more enduring changes for the autistic child and the family as a whole. Case illustrations are provided.

Skills Training for Spouses of Patients with Alzheimer's Disease: Outcomes of an Intervention Study

The effects of a 12-week intervention on a patient-focused skills training group and a caregiver-focused skills training group were compared with those on a control group that received comparable attention, but no training. Intervention effects were monitored at the completion of the treatment phase and at 3- and 6-months postintervention. Treatment implementation was documented in a comprehensive fashion to ensure replicability. Both training groups acquired skills that enabled them to improve targeted behaviors (patient problem behaviors and caregiver mood, respectively). Weaker effects were found for more distal outcomes, such as depression, perceived stress, caregiver strain, and self-efficacy.     

Updating the Textbook: A Novel Approach to Training Graduate Students in Evidence-Based Youth Practices

Despite the ever-improving base of evidence-based practices (EBPs) for the treatment of childhood disorders, a gap between EBP research and their use in community settings continues to exist. An exciting opportunity to close this gap exists in the form of graduate student training; however, at present, several roadblocks exist. In this paper, we review the current state of graduate training in delivering EBPs and obstacles involved in training future community clinicians (i.e., graduate students) in EBPs. Next, we describe in detail our initiative to develop a curriculum that addresses these challenges. This innovative course empowered graduate students to receive training in the delivery of youth EBPs in community settings through reviews of the research literature, active learning techniques (e.g., discussions of case conceptualizations, role-playing case studies), and a written, publication-quality review of EBPs. Finally, we offer recommendations for other educators of mental health professionals (e.g., psychologists, social workers, counselors) to improve upon this curriculum in their training of graduate students in the theory and application of EBPs for treating childhood disorders.     

Reduced-Frequency Concurrent and Terminal Feedback: A Test of the Guidance Hypothesis

In 2 experiments, the authors manipulated the frequency of concurrent feedback to discern the effects on learning. In each experiment, participants (N = 48, Experiment 1; N = 36, Experiment 2) attempted to reproduce a criterion force-production waveform (5 s in duration) presented on the computer monitor. Consistent with the guidance hypothesis, the results of Experiment 1 indicated very strong guiding effects of concurrent feedback and strong dependence on the feedback, as indicated by participants' extremely poor performance upon feedback withdrawal in retention. As predicted by the guidance hypothesis, dependence on the feedback was reduced as a result of reducing the frequency of the concurrent feedback. The results of Experiment 2 indicated that one can enhance learning by providing concurrent and terminal feedback on 1 trial, with no feedback on the subsequent trial. In that way, the strong guiding effects of concurrent feedback could be realized and the beneficial effects of terminal feedback could also be achieved.
