Understanding therapists' perceived determinants of trauma narrative use.

BACKGROUND: Trauma narratives are a critical, exposure-based component of trauma-focused cognitive-behavioral therapy, yet community therapists rarely use them. Given evidence that intentions to deliver elements of cognitive behavioral therapy vary by component, and that intentions to deliver exposure are the weakest, this study focused specifically on trauma narratives. We drew on a social psychology causal theory (Theory of Planned Behavior (TPB)) and an implementation science framework (the Consolidated Framework for Implementation Research (CFIR)) to glean insight into multilevel influences on trauma narrative use. While the CFIR offers a broad list of factors potentially affecting implementation, the TPB offers causal pathways between individual-level constructs that predict behavior, including the uptake of an evidence-based intervention. The integration of these approaches may provide a more complete understanding of factors affecting therapists' use of TNs. METHODS: Therapists (n=65) trained in trauma-focused cognitive behavioral therapy completed a survey about their use of and beliefs about trauma narratives. Content analysis was used to identify common beliefs about trauma narratives. A subset of participants (n=17) completed follow-up qualitative interviews, which were analyzed using an integrated approach informed by the CFIR. RESULTS: While most participants reported high intentions to use TNs, nearly half reported that they did not use TNs in the last 6 months. Survey data indicate a number of TPB-related determinants related to using trauma narratives. Qualitative interviews identified CFIR-relevant contextual factors that may influence constructs central to TPB. CONCLUSIONS: These results highlight the importance of integrating approaches that address multiple theoretical determinants of therapist behavior, including therapist, organizational, and client factors with causal explanations to explain implementation behavior.

Comparing a Practice-Based Model with a Research-Based Model of social skills interventions for children with autism in schools.

Background: Social impairment is the most challenging core deficit for children with autism spectrum disorder (ASD). Several evidence-based interventions address social impairment in children with ASD; however, adoption, use, and implementation of these interventions in schools is challenging. Method: Ninety-two children with ASD who received one of three intervention models: a) School personnel adapted and implemented evidence-based social skills intervention (Practice-Based Model; n = 14); b) University researcher developed and implemented evidence-based social skills intervention (Research-Based Model; n = 45); or c) standard educational practices model (Inclusion Only Model; n = 33) participated. The average age was 8.4 (SD = 1.6) years; majority was male (88%) and white (52.2%). Typically developing classmates completed sociometric ratings to determine children's social network inclusion, and independent raters observed children on the playground using a time-interval behavior coding system to record solitary engagement and frequency of initiations. Results: Separate linear regression models were conducted. Children in the Research-Based Model had significantly higher social network inclusion than children in the other two settings (p = .05). Children in the Practice-Based Model had significantly lower solitary engagement (p = .04) and more initiations on the playground than children in the University Developed Model (p = .04). Conclusions: The results suggest that researchers: 1) may learn from public school stakeholders who have lived experiences to better understand the context in which implementation occurs; and 2) should partner with schools to learn about their processes of adaptation and adoption in order to facilitate successful implementation of evidence-based practices for children with ASD. Interventions designed with implementation in mind may be more feasible and increase the chances of use in schools.

Pebbles, rocks, and boulders: The implementation of a school-based social engagement intervention for children with autism.

Few evidence-based practices, defined as the use of empirically supported research and clinical expertise for children with autism, have been successfully implemented and sustained in schools. This study examined the perspectives of school personnel ( n = 39) on implementing a social engagement intervention for children with autism. Semi-structured interviews, informed by the Domitrovich et al. (2008) framework, were conducted. Participants were asked about (1) school factors that affect the general implementation of evidence-based practices, (2) their specific experiences implementing the social engagement intervention, and (3) barriers to and facilitators of implementing the social engagement intervention. Data were analyzed using an integrated approach. General (e.g. implementation process, leadership, support, and staff) and intervention-specific (e.g. staff, barriers, and facilitators) implementation themes were identified. These findings suggest that a variety of factors should be considered when implementing evidence-based practices in schools and that implementing social engagement interventions for children with autism may require additional specific support for implementation.

The Effect of Parenting Style on Social Smiling in Infants at High and Low Risk for ASD.

This study examined how parenting style at 9 months predicts growth in infant social engagement (i.e., social smiling) between 9 and 18 months during a free-play interaction in infants at high (HR-infants) and low (LR-infants) familial risk for autism spectrum disorder (ASD). Results indicated that across all infants, higher levels of maternal responsiveness were concurrently associated with higher levels of social smiling, while higher levels of maternal directiveness predicted slower growth in social smiling. When accounting for maternal directiveness, which was higher in mothers of HR-infants, HR-infants exhibited greater growth in social smiling than LR-infants. Overall, each parenting style appears to make a unique contribution to the development of social engagement in infants at high- and low-risk for ASD.

Correlation of cognitive and social outcomes among children with autism spectrum disorder in a randomized trial of behavioral intervention.

Although social impairments are considered the hallmark deficit of autism, many behavioral intervention studies rely on cognitive functioning as a primary outcome. Fewer studies have examined whether changes in cognition are associated with changes in social functioning. This study examined whether cognitive gains among 192 students from 47 kindergarten-through-second-grade autism support classrooms participating in a year-long behavioral intervention study were associated with gains in social functioning. Children's gains in cognitive ability were modestly associated with independent assessors' and teachers' evaluations of social functioning but were not associated with changes in parent ratings. Observed social gains were not commensurate with gains in cognition, suggesting the need both for interventions that directly target social functioning and relevant field measures of social functioning.

Computed tomography without oral contrast solution for blunt diaphragmatic injuries in abdominal trauma.

OBJECTIVE: The aim of this study was to estimate the sensitivity, specificity, and positive predictive value (PPV) of computed tomography (CT) without oral contrast for diaphragm injuries (DIs) in blunt abdominal trauma. METHODS: We prospectively enrolled 500 consecutive "trauma-one" patients who received CT imaging and interpretation (CT-Read1) of the abdomen within 45 minutes of their arrival from July 2000 to December 2001. All patients were imaged without oral contrast but with intravenous contrast. Computed tomographic images were reviewed within 24 hours of admission by research radiologists (CT-Read2) blinded to CT-Read1. True DIs were determined hierarchically by either laparotomy or autopsy. RESULTS: There were 9 patients with laparotomy or autopsy-proven blunt DIs; 8 of these injuries involved the left hemidiaphragm. The CT-Read1 correctly detected only 6 of 9 blunt DIs, thus missing 3 DIs. One of these involved the right hemidiaphragm, whereas the other 2 were left sided. There were no false-positive findings with CT-Read1 for blunt DI. The sensitivity and specificity of CT imaging with respect to DI were 66.7% (95% CI, 29.9%-92.5%) and 100% (95% CI, 99.2%-100%), respectively. The PPV for the test was 1.00 (95% CI, 0.65-1.00). CONCLUSION: Although the low number of blunt DIs in this study limits its general applicability, CT imaging of the diaphragm without oral contrast appears to perform within the range of reported imaging techniques using oral contrast. Still, CT scanning appears to have an unsatisfactorily low sensitivity to be reliably used in eliminating the diagnosis of blunt DI.

Retrievable vena cava filters in trauma patients for high-risk prophylaxis and prevention of pulmonary embolism.

BACKGROUND: Venous thromboembolic (VTE) disease remains a significant cause of morbidity for trauma patients because many patients have injuries that may preclude effective VTE prevention and treatment. Retrievable vena cava filters may prove beneficial in this subset of trauma patients. METHODS: Trauma patients at risk for VTE were identified and managed by institutional protocol. Patients who required a vena cava filter were managed with a device that could be retrieved or left in situ. A retrospective review of medical records was used to identify the use, indications, and complications associated with a retrievable filter. RESULTS: Fifty-three retrievable filters were placed in 51 patients. Two of these patients received a second filter, and 1 received a filter in the superior vena cava. Thirty-two filters were placed prophylactically, whereas 21 were placed for demonstrated venous thromboembolism (VTE). Retrieval was successful in 24 of 25 attempts. Twenty-nine filters became permanent: 10 for continued contraindications to anticoagulation without known VTE, 12 for known VTE and continued contraindications to anticoagulation, 1 for technical reasons, and 6 because of patient death. There were no complications of bleeding, device migration or thrombosis, infection, or pulmonary embolism. CONCLUSIONS: A retrievable vena cava filter appears safe and effective for the prevention of pulmonary embolism in the high-risk trauma patient who cannot receive anticoagulation.

Computed tomographic scanning without oral contrast solution for blunt bowel and mesenteric injuries in abdominal trauma.

BACKGROUND: Computed tomographic (CT) scanning using intravenous and oral contrast material has traditionally been advocated for the evaluation of intra-abdominal injury, including blunt bowel and mesenteric injuries (BBMIs). The necessity of oral contrast in detecting these injuries has recently been called into question. The purpose of this study was to determine the sensitivity and specificity of CT scanning without oral contrast for BBMIs. METHODS: We prospectively enrolled 500 consecutive blunt trauma patients who received CT imaging and interpretation (CT-Read1) of the abdomen from July 2000 to November 2001. All patients were imaged without oral contrast, but with intravenous contrast. CT images were reviewed within 24 hours of admission by a research radiologist (CT-Read2) blinded to CT-Read1. For study purposes, true BBMI was determined to be present if either laparotomy or autopsy identified bowel or mesenteric injury, or both CT-Read2 and the hospital discharge summary described bowel or mesenteric injury. Three-month telephone follow-up was also completed. RESULTS: CT-Read1 detected 19 of 20 bowel and mesenteric injuries. CT-Read1 missed one duodenal perforation. There were two patients with false-positive interpretations of CT-Read1 for bowel injury. The sensitivity and specificity of CT imaging for the detection of BBMIs were 95.0% and 99.6%, respectively. CONCLUSION: CT imaging of the abdomen without oral contrast for detection of BBMIs compares favorably with CT imaging using oral contrast.
