This pilot study evaluated the effectiveness of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) training programs augmented with a systematic “PRACTICE What You Preach” (PWYP) self-care focus, which has trainees personally utilize the coping skills they teach their clients. Participants were 115 clinicians/supervisors who completed a PWYP TF-CBT training program. Pre- to post-training analyses documented significant increases in participants’ competency and fidelity in implementing TF-CBT (ps < .001), significantly more frequent use of coping skills including instrumental social support (p < .01), active coping (p < .001), humor (p < .01), and restraint (p < .01), and significant decreases in secondary traumatic stress (STS; p < .001). Children’s symptoms of PTSD (ps < .001) and behavior problems (p < .05) also decreased significantly. This preliminary evidence suggests that training augmented with PWYP may enhance clinicians’/supervisors’ personal coping and reduce their levels of STS without compromising treatment implementation efforts and client outcomes.

A large hemi-anechoic "sound-absorbing walls and acoustically hard floor… noise control enclosure was erected around a complex of test stands at the NASA Lewis Research Center in Cleveland, Ohio. This new state-of-the-art Aeroacoustic Propulsion Laboratory provides an all-weather, semisecure test environment while minimizing noise levels in surrounding residential neighborhoods. The 39.6-m-diam "130-ft-diam… geodesic dome houses the new nozzle aeroacoustic test rig, an ejector-powered Mach 0.3 free-jet facility for acoustical testing of supersonic aircraft exhaust nozzles and turbomachinery. A multiaxis, force-measuring powered lift facility stand for testing short-takeoff vertical-landing vehicles is also located in the dome. The design of the Aeroacoustic Propulsion Laboratory efficiently accommodates the research functions of the two separate rigs, while providing a specialized environment for measuring far-field sound-pressure levels from the nozzle aeroacoustic test rig. Sound-absorbing fiberglass wedges on the interior surface of the dome provide a hemi-anechoic environment. The Aeroacoustic Propulsion Laboratory is the first known geodesic dome structure to incorporate transmission-loss properties as well as interior absorption in a free-standing community-compatible, hemi-anechoic test facility.

Clinicians working with youth exposed to trauma may be at increased risk for experiencing elevated levels of stress and symptoms of secondary traumatic stress, which can negatively impact clinician wellbeing and ultimately contribute to reduced access to quality care for clients. An innovative Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) training incorporating self-care practices (i.e., Practice What You Preach; PWYP) was developed to help facilitate the implementation of TF-CBT and to enhance clinicians’ coping and decrease stress. The primary purpose of this study was to determine whether the PWYP-augmented training met three Objectives: (1) increase clinicians’ feelings of TF-CBT competency; (2) improve clinicians’ coping abilities/reduce clinicians’ stress; and (3) increase clinicians’ insight into the benefits and/or challenges clients may experience in treatment. An exploratory aim was also developed to identify additional facilitators and barriers of TF-CBT implementation. The written reflections of 86 community-based clinicians who participated in the PWYP-augmented TF-CBT training were examined using qualitative methods. The majority of clinicians indicated increased feelings of competency and improved coping abilities and/or stress levels; almost half mentioned increased insight into clients’ experiences. The most frequently mentioned additional facilitators were related to elements of the TF-CBT treatment model. Anxiety/self-doubt was the barrier most frequently mentioned, though all clinicians who mentioned this barrier indicated it lessened or resolved over the course of the training. Incorporating self-care strategies into trainings may serve as a facilitator for TF-CBT implementation by enhancing the competency and well-being of clinicians. The additional insights into barriers and facilitators can be used to further improve the PWYP initiative and future training and implementation efforts.

At the NASA Glenn Research Center, science experiment payloads developed for the International Space Station are designed to meet noise emission criteria that promote hearing conservation and speech intelligibility goals. A key component in the successful design of low-noise hardware is the frequent use of acoustical testing as a diagnostic and design verification tool. NASA has designed and constructed a convertible hemi/anechoic acoustical testing laboratory that provides convenient access to accurate and repeatable sound pressure level measurements as well as state-of-the art capabilities for sound power level testing per ANSI S12.35 using a multichannel PC-based data acquisition system. The laboratory consists of a 100-Hz hemianechoic chamber, vibration-isolated to 3 Hz, with 21′×17′×17′(h) interior working dimensions and removable floor wedges. A separate, sound-isolated control room doubles as a test support equipment enclosure when testing flight hardware that requires remote connections to high-noise support equipment and utilities. Movable modular furnishings facilitate reconfiguration of the enclosure, and data acquisition and test control functions are easily relocated to an adjacent quiet area. The Glenn Research Center Acoustical Testing Laboratory also offers a full range of noise control services to assist payload developers with meeting the ISS noise emission criteria.
