Title: EXPLORING A RELATIONSHIP BETWEEN SOCIAL ANXIETY DISORDER AND BILINGUALISM.
Creator: James, Nicholas, Beidel, Deborah, University of Central Florida
Abstract / Description: This study investigated the possible relationship between bilingualism and social anxiety disorder. Past research has indicated developmental delays in language as increasing risk for other psychological difficulties. With the pressure to learn two languages, possibly in the drastically different environments of home, school, and/or work, individuals may be vulnerable to becoming socially anxious in conjunction with language use.

Show moreThis study investigated the possible relationship between bilingualism and social anxiety disorder. Past research has indicated developmental delays in language as increasing risk for other psychological difficulties. With the pressure to learn two languages, possibly in the drastically different environments of home, school, and/or work, individuals may be vulnerable to becoming socially anxious in conjunction with language use. This study examined a series of factors surrounding linguistic development and reports of social anxiety. Participants were divided into 4 groups: Socially Anxious (SA; n = 43) monolinguals, Non-Socially Anxious (Non-SA; n = 81) monolinguals, SA bilinguals (n = 30), and Non-SA bilinguals (n = 43). Measures of social anxiety, linguistic ability, and demographic information were collected and compared. The results of this study showed no direct link between bilingualism and SAD. However results raised other questions as there was an overrepresentation of SA bilinguals having accents when compared with Non-SA bilingual individuals.

Title: PREDICTORS OF PRESENCE IN VIRTUAL REALITY.
Creator: Sollins, Brandon, Beidel , Deborah, University of Central Florida
Abstract / Description: The subjective experience of presence is considered to be important in the treatment of anxiety disorders using virtual reality. Presence can be defined as a psychological phenomenon through which one's cognitive processes are oriented towards another world. Most of the research on presence has focused on the roles of technological factors influencing presence, while the number of studies focusing on the personality and physiological predictors are far fewer. Thus, the present study examined...
Show moreThe subjective experience of presence is considered to be important in the treatment of anxiety disorders using virtual reality. Presence can be defined as a psychological phenomenon through which one's cognitive processes are oriented towards another world. Most of the research on presence has focused on the roles of technological factors influencing presence, while the number of studies focusing on the personality and physiological predictors are far fewer. Thus, the present study examined the relationship between various personality variables and presence, along with physiological correlates of presence when engaged in a virtual environment. The Presence Questionnaire, to determine their experience of presence, and a small battery of personality-related questionnaires were administered to 70 young adults who participated in 3 different virtual reality scenarios. Participants' physiological responses were recorded in the form of heart rate, galvanic skin levels, and galvanic skin responses were assessed as were urges to drink (craving). Data analysis showed that expectations, levels of craving, and drinking history played a significant role in the experience of presence.

Title: DOES BEHAVIORAL TREATMENT FOR CHILDREN WITH SOCIAL ANXIETY DISORDER CHANGE VOCAL CHARACTERISTICS?.
Creator: Kroytor, Anya, Beidel, Deborah, University of Central Florida
Abstract / Description: Children with Social Anxiety Disorder (SAD) characterized by persistent shyness and anxiety in social or performance situation, exhibit social skills deficits. These deficits include difficulty initiating conversations, maintaining eye contact, and taking turns when speaking, which in turn leads to impairments in their daily interactions and development of peer relationships (Greco, 2005; Miers, 2010). Although there are many subjective assessments for treatment outcomes for children with SAD...
Show moreChildren with Social Anxiety Disorder (SAD) characterized by persistent shyness and anxiety in social or performance situation, exhibit social skills deficits. These deficits include difficulty initiating conversations, maintaining eye contact, and taking turns when speaking, which in turn leads to impairments in their daily interactions and development of peer relationships (Greco, 2005; Miers, 2010). Although there are many subjective assessments for treatment outcomes for children with SAD, in order to become more thorough and effective when assessing treatment outcomes, more objective measures of actual behaviors are needed. This study uses digital vocal analysis to examine vocal parameters associated with anxiety such as pitch and volume in children with SAD pre and post treatment. Measuring vocal parameters during role-play behavioral assessment tasks allowed us to examine whether the software was capable of detecting differences in vocal characteristics that are consistent with the clinical presentation of the disorder. Children with SAD showed differences in vocal characteristics pre to post treatment, in regards to pitch, pitch variability, volume, and volume variability. There were significant changes in volume pre to post treatment, however the changes in pitch, pitch variability, and volume variability were not significant. These results suggest that post SET-C treatment, certain vocal characteristics, (one of the social skills deficits exhibited by children with SAD) improved. Implications of the findings are discussed.

Show moreChildren with Asperger's Disorder are considered to have impairments in social interaction, but to date few studies have empirically addressed this issue. This study examined the existence of social skills deficits in children with Asperger's Disorder, children with social phobia, and children with no psychological disorder. Using direct observation of social skills during role-play tasks, blinded observers rated an overall impression of social effectiveness and three specific categories of social skill: pragmatic behavior (e.g., effort to maintain conversation, latency to respond), speech and prosodic behavior (e.g., vocal inflection, voice volume), and paralinguistic conversational behaviors (e.g., facial orientation, motor movement). Children with Asperger's Disorder did not display predicted social skills deficits when compared to typically developing children. When compared to children with social phobia, children with Asperger's Disorder were rated as significantly more socially effective and were rated as more skilled on the molecular conversational behaviors that create an overall impression of social effectiveness. These results suggest that children with Asperger's Disorder display adequate social skill during brief social interactions. Furthermore, the social skills deficits present in children with social phobia are not the same deficits found in children with Asperger's Disorder. Implications of the findings are discussed.

Show moreRecognizing emotion from facial expressions is an essential skill for effective social functioning and establishing interpersonal relationships. AspergerÃ‚Â's Disorder (AD) and Social Phobia (SP) are two clinical populations showing impairment in social skill and perhaps emotion recognition. Objectives: The primary objectives were to determine the uniqueness of facial emotion recognition abilities between children with AD and SP relative to typically developing children (TD) and to examine the role of expression intensity in determining recognition of facial affect. Method: Fifty-seven children (19 AD, 17 SP, and 21 TD) aged 7-13 years participated in the study. Reaction times and accuracy were measured as children identified neutral faces and faces displaying anger, disgust, fear, happiness, and sadness at two different intensity levels. Results: Mixed model ANOVAs with group and emotion type revealed that all children responded faster and more accurately to expressions of happiness, but there were no other group differences. Additional analyses indicated that intensity of the displayed emotion influenced facial affect detection ability for several basic emotions (happiness, fear, and anger). Across groups, there was no pattern of specific misidentification of emotion (e.g., children did not consistently misidentify one emotion, such as disgust, for a different emotion, such as anger.) Finally, facial affect recognition abilities were not associated with behavioral ratings of overall anxiety or social skills effectiveness in structured role play interactions. Conclusions: Distinct facial affect recognition deficits in the clinical groups emerge when the intensity of the emotion expression is considered. Implications for using behavioral assessments to delineate the relationship between facial affect recognition abilities and social functioning among clinical populations are discussed.

Show moreOVERVIEW: Social anxiety disorder is the third most prevalent psychiatric disorder in the United States. Dissociation can arise during acute daily social stressors in individuals with social anxiety. This study examined the relationship between social anxiety and functional outcomes (i.e., alcohol-related consequences and relationship satisfaction) as moderated by levels of dissociation (i.e., depersonalization/derealization). It was hypothesized that dissociation would moderate the relationships between social anxiety and alcohol-related consequences and between social anxiety and relationship satisfaction. METHOD: College students who endorsed alcohol use within the past 30 days (n = 320) and college students who reported having been in a romantic relationship lasting 30 or more days (n = 364) were recruited through the Psychology Department's Sona system. All participants completed measures of social anxiety, dissociation, alcohol use motives, alcohol-related consequences, and relationship satisfaction as part of an online questionnaire. RESULTS: Findings indicated no moderation effect in either model; both social anxiety and dissociation predicted alcohol-related consequences via coping-motivated alcohol use. Additionally, there was a negative association between dissociation and relationship satisfaction. CONCLUSIONS: Future research should include longitudinal research designs or ecological momentary assessment designs and should examine these relationships in clinical samples.

Show moreBackground: Exposure therapy (EXP) is a first-line intervention for combat-related PTSD. EXP works by repeatedly exposing the patient to the feared stimuli, situation, or physical sensations in the absence of actual danger until the stimuli no longer evoke maladaptive responses. Over the past decade, multiple technologies have been introduced to augment the EXP process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase patients' sense of presence. Exploratory research has only broadly examined the effect of odorants on the patient's sense of presence during simulated exposure tasks. This study hypothesized that those with autobiographical memories similar to the virtual environment (VE) and those who received odorants would report experiencing more presence than experimental controls. Methods: 61 veterans and civilian subjects were randomized and asked to participate in a virtual environment simulating a routine OIF/OEF/OND convoy. The effects of odorants and autobiographical memory on presence were assessed via electrodermal activity, respiration, heart rate variability, and self-report measures. Results: Odorants did not significantly influence presence. A relationship between military experience and presence, HRV, and realism was observed. Conclusion: Odorants did not have a statistically significant effect on presence while engaged in a simulated exposure task, which was inconsistent with previous research. The rationale for these findings and recommendations for future research are made.

Title: How Much is Enough? Trauma Recall and the Exposure Therapy Process.
Creator: Morrison, Krystal, Beidel, Deborah, Bowers, Clint, Bohil, Corey, University of Central Florida
Abstract / Description: Prevailing theoretical models of posttraumatic stress disorder (PTSD) as well as exposure therapy (EXP) methodology suggest that recall of a trauma is crucial to altering the conditioned fear response associated with PTSD (Benito (&) Walther, 2015; Craske et al., 2008; Foa (&) Kozak, 1986).

Show morePrevailing theoretical models of posttraumatic stress disorder (PTSD) as well as exposure therapy (EXP) methodology suggest that recall of a trauma is crucial to altering the conditioned fear response associated with PTSD (Benito (&) Walther, 2015; Craske et al., 2008; Foa (&) Kozak, 1986). However, it is unclear whether limited recall of the event impacts the EXP process and treatment outcomes. This study examined whether incomplete trauma recall affected pre-treatment PTSD severity, Initial Fear Activation (IFA), Overall Fear Activation (OFA), Within-Session Habituation (WSH), Between-Session Habituation (BSH; overall extinction), average length of EXP sessions, number of EXP sessions, and post-treatment PTSD severity, in 166 veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn, who completed EXP treatment. Contrary to predicted outcomes, the extent of recall did not attenuate veterans' participation in EXP as measured by IFA, OFA, WSH and BSH. Furthermore, less recall did not result in more severe pre-treatment PTSD, longer EXP sessions, more EXP sessions, or attenuated treatment response, as measured by the Clinician-Administered PTSD Scale for DSM-IV (CAPS; Weathers, Ruscio, (&) Keane, 1999) and PTSD Checklist Military Version (PCL-M; Weathers, Huska, (&) Keane, 1991) at pre- and post-treatment. This suggests that veterans who are unable to recall aspects of their traumatic experience can engage successfully and benefit equally from EXP akin to veterans who experience less difficulty recalling trauma details. This research is the first to examine trauma recall in the context of the EXP process and contributes to the current body of literature that aims to address the question: For whom do treatments work?

Show moreA comprehensive sleep assessment of 45 firefighters was conducted over 9- days in an effort to determine the impact of their 24 hour work and 48 hour off work schedule on their sleep duration, sleep quality, processing speed, sustained attention, vigilance, and mental health. Chronic patterns of poor sleep are associated with an increased likelihood of performing poorly on tasks that require processing speed and sustained attention/vigilance which could lead to firefighters' suboptimal work performance or an increased risk of injury. Firefighters completed sleep actigraphy, self- report measures, as well as neuropsychological sub-tests at their beginning of their shift and immediately at the end of their work shift. As measured by actigraphy, firefighters in this sample slept an average of 5 hours and 20.99 minutes at work, which was significantly less than was found in a large sample of U.S. working adults. Firefighters endorsed poor sleep efficiency and poor sleep quality as assessed by self-report and objective actigraphy. One limitation is that only 12 of the 45 firefighters endorsed responding to a nighttime call during the work night that occurred between the two neuropsychological assessments. Comparing changes in neuropsychological performance between firefighters who had disrupted sleep compared to firefighters who did not, significant performances decrements were evident only for the psychomotor vigilance test (PVT) reaction time. If confirmed with a larger sample, the results suggest that reaction time may be a sensitive indicator of decreasing cognitive performance because of sleep loss. Limitations, future study directions, and recommendations are discussed.

Show moreFunctional near-infrared spectroscopy (fNIRS) is a neurophysiological procedure that offers immense clinical utility due to its cost effectiveness, ease of use, and mobile application. Using fNIRS to measure neurological reactions to personalized trauma-related cues might strengthen diagnostic screening, tailor treatment planning, and improve detection of remission among individuals with posttraumatic stress disorder (PTSD). Odors elicit strong emotional responses but remain underutilized in clinical research. This fNIRS study examined whether personalizing combat-related odors and sounds to have a higher or lower match to distressing combat experiences increased the observed neurological effect among combat veterans with and without combat-related PTSD. This study gathered data from 58 male, right-handed combat veterans of Iraq or Afghanistan, ages 26 to 68, recruited from the community. The results indicated a significant increase in activation at the left ventral lateral prefrontal cortex (VLPFC) following an interaction between higher PTSD severity and higher match ratings for the combat-related odors (R2 = .20, p = .003; f2 = .25). Furthermore, the left VLPFC showed a significant increase in activation following an interaction between having a PTSD diagnosis and higher match ratings for the combat-related odors (R2 = .25, p = .005; f2 = .33). The findings for the combat-related sounds were less clear. The left VLPFC is associated with facilitating regulation of memory and emotional processes. Overall, the presentation of odors with higher similarity to distressing combat experiences altered the neurological response of the prefrontal cortex and may contribute to better understanding of the neurophysiological mechanisms of combat-related PTSD.

Show moreThe current DSM-5 criteria for Posttraumatic Stress Disorder (PTSD) affords heterogeneous symptom presentations; however, current treatment fails to consider differences in trauma frequency and trauma type. These different symptom profiles that exist within the PTSD framework lead to questions about the generalizability of treatment outcomes from one group to another group. One group of interest is those that experience multiple traumatic events and report multiple index traumas (trauma frequency). The second group of interest is those with a PTSD diagnosis from occupational exposure to traumatic events (trauma type). Appreciation of the reinforcement schedule may be particularly crucial for understanding treatment response. The current study aims to investigate habituation responses during exposure therapy to inform treatment modifications and decisions. Exposure therapy process variables, session variables, and PTSD severity were examined for a sample of 128 participants that sought treatment for combat-related PTSD or occupation-related PTSD, some of whom endorsed multiple index traumas, and some of whom endorsed a single index trauma. Results revealed no significant differences based on trauma frequency or trauma type for within-session and between-session habituation. This suggests that the effectiveness of a flooding approach to extinguish avoidance behavior may overcome the impact of reinforcement schedule on fear habituation. The results of the present study contribute to the growing body of literature that suggests the exclusion of patients based on the pre-treatment characteristics of trauma frequency and trauma type is unfounded.

Show moreOVERVIEW: Psychopathy has been an area of growing interest in psychology for the last half century. Currently, the most common conceptualization of psychopathy breaks it down into two factors: primary and secondary psychopathy. More recently, psychopathy has been viewed through a more nuanced model, the Triarchic Model of Psychopathy. The present study examines the relationship between the three facets of the Triarchic Model and alcohol pathology via aspects of impulsivity and Protective Behavioral Strategies (PBS). METHOD: A college student sample of n = 967 individuals who endorsed consuming alcohol completed surveys regarding the Triarchic Model, impulsivity, PBS use, and alcohol pathology. RESULTS: Our findings indicate that boldness and disinhibition are significant predictors of alcohol pathology. Boldness was partially mediated by conscientiousness, while disinhibition was partially mediated by both conscientiousness and PBS use. Meanness was not associated with higher levels of alcohol pathology. CONCLUSIONS: It seems that aspects of psychopathy related to disinhibition and boldness are predictive of alcohol pathology, while meanness, though similar to primary psychopathy, does not relate to alcohol pathology as hypothesized. This thesis not only adds to the literature between psychopathy and alcohol pathology but allows for a more exact insight regarding aspects of psychopathy and their relation to alcohol pathology.

Show moreThe (")research-to-practice(") gap is a problem that the field of medicine faces regarding disseminating findings from research into the field of practice. The traditional methods of disseminating best practices, using workshops and manuals, has been found to be ineffective. Several more active learning strategies, such as the use of behavioral models and behavioral rehearsals have been suggested as possible alternatives that may increase transfer of knowledge after a training. Additionally, web-based trainings have been suggested as another possible avenue for increasing dissemination of evidence-based practices. This is particularly important for evidence-based treatments such as Exposure Therapy for PTSD which suffers a (")public relations problem(") in the field of mental health.This study examined the utility of using a video model to disseminate the skill of fear hierarchy construction for patients with PTSD. Analyses were conducted using a moderated mediation model looking at how video modeling or script condition moderate the relationship between condition and change in self-efficacy, and if this change mediates the relationship between condition and change in fear hierarchy skill. Self-efficacy and positive attitudes toward exposure therapy were increased, however, there was no connection between treatment condition and change in skill. The study's findings suggest that short online trainings may be effective at reducing negative attitudes toward EBTs, and at increasing self-efficacy for a related skill of fear hierarchy construction.

Show moreStress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration. Specifically, this study assessed the effects of Immersion (Non-immersive, Semi-immersive, Fully-immersive) and Exploration (Passive vs Active) on stress reduction and cognitive restoration. Additionally, restoration from the most effective virtual nature environment was compared to that of taking an active coloring break. Eighty-three university students with normal color vision, depth perception and good visual acuity participated in this study. The overall findings of the study suggest that virtual nature is able to reduce stress and anxiety, generally the more immersive and interactive the better. Moreover, though both the those in the passive VR nature condition and those in the coloring condition reported a reduction in stress, only those in the passive VR nature condition exhibited the physiological changes indicative of stress reduction.

Show moreImpulsivity is a hallmark of two of the three DSM-IV ADHD subtypes and is associated with myriad adverse outcomes. Limited research, however, is available concerning the mechanisms and processes that contribute to impulsive responding by children with ADHD. The current study tested predictions from two competing models of ADHD (-) working memory (WM) and behavioral inhibition (BI) (-) to examine the extent to which ADHD-related impulsive responding was attributable to model-specific mechanisms and processes. Children with ADHD (n = 21) and typically developing children (n = 20) completed laboratory tasks that provided WM (domain-general central executive [CE], phonological/visuospatial storage/rehearsal) and BI indices (stop-signal reaction time [SSRT], stop-signal delay, mean reaction time). These indices were examined as potential mediators of ADHD-related impulsive responding on two diverse laboratory tasks used commonly to assess impulsive responding (CPT: continuous performance test; VMTS: visual match-to-sample). Bias-corrected, bootstrapped mediation analyses revealed that CE processes significantly attenuated between-group impulsivity differences, such that the initial large-magnitude impulsivity differences were no longer significant on either task after accounting for ADHD-related CE deficits. In contrast, SSRT partially mediated ADHD-related impulsive responding on the CPT but not VMTS. This partial attenuation was no longer significant after accounting for shared variance between CE and SSRT; CE continued to attenuate the ADHD-impulsivity relationship after accounting for SSRT. These findings add to the growing literature implicating CE deficits in core ADHD behavioral and functional impairments, and suggest that cognitive interventions targeting CE rather than storage/rehearsal or BI processes may hold greater promise for alleviating ADHD-related impairments.

Creator: Middleton, Melissa, Renk, Kimberly, Beidel, Deborah, Sims, Valerie, University of Central Florida
Abstract / Description: To examine the relationships among the match between parent and child temperament, parenting behaviors, parenting stress, and young children's behavior problems, the current study investigated the responses of mothers who are raising children between the ages of 3- and 5-years. Mothers completed the Dimensions of Temperament Scale-Revised for Children (Windle (&) Learner, 1986), the Dimensions of Temperament Scale-Revised for Adults (Windle (&) Learner, 1986), the Alabama Parenting...
Show moreTo examine the relationships among the match between parent and child temperament, parenting behaviors, parenting stress, and young children's behavior problems, the current study investigated the responses of mothers who are raising children between the ages of 3- and 5-years. Mothers completed the Dimensions of Temperament Scale-Revised for Children (Windle (&) Learner, 1986), the Dimensions of Temperament Scale-Revised for Adults (Windle (&) Learner, 1986), the Alabama Parenting Questionnaire-Preschool Revision (Clerkin, Marks, Policaro, (&) Halperin, 2007), the Maternal Emotional Styles Questionnaire (Lagac(&)#233;-S(&)#233;guin (&) Coplan, 2005), the Parenting Stress Index-Short Form (Abidin, 1995), and the Child Behavior Checklist (Achenbach (&) Rescorla, 2000, 2001). Using cluster analyses, results of this study revealed two temperament clusters (i.e., Difficult Temperament and Easy Temperament) between mothers and their young children. Results revealed that mothers in the difficult temperament cluster report using less positive parenting, less emotion-coaching parenting, and more negative/inconsistent parenting. They also report a higher level of parenting stress. Additionally, results indicated that, when all variables were examined together, only mothers' ratings of parenting stress contribute significantly to their young children's internalizing behavior problems and only mothers' ratings of parenting stress and punitive parenting behavior contribute to their young children's externalizing behavior problems. Further, results also revealed that parenting stress fully mediates the relationship between the mother-child temperament match and young children's behavior problems. Such findings suggested that interventions would benefit from targeting parents' own temperamental characteristics and how these characteristics fit with the characteristics of their young children as well as from addressing the role that this match plays in predicting parenting stress and young children's emotional and behavioral problems.

Title: Accuracy of the Peer Informant: What Characteristics Are Related to the Ability to Detect Behavior Problems in Peers?.
Creator: Lauer, Brea-anne, Renk, Kimberly, Beidel, Deborah, Sims, Valerie, University of Central Florida

Show moreVictimization and rejection by peers leads to and exacerbates behavior problems in children and adolescents. Given the implications of problematic peer relations for adolescents who experience behavior problems, the present study examined factors that may be related to how adolescents perceive peers who exhibit such problems. Specifically, the present study examined the relationship of adolescent peer informants' socioeconomic status, their prior exposure to psychopathology, their own social competence, and their own behavior problems to their perceptions of peer internalizing and externalizing behavior problems, their liking of individuals who exhibit such problems, and their attributions for the etiology of such problems when portrayed by fictitious adolescents of the same age. In particular, adolescents were asked to rate a set of vignettes that portray internalizing and externalizing behavior problems that are seen commonly in peers and to complete a set of brief questionnaires. Results revealed that adolescents are able to accurately detect the presence of both internalizing and externalizing behavior problems in vignette characters. Additionally, vignette characters who display behavior problems received significantly lower liking ratings. Finally, although adolescents endorsed both internal and external etiological factors, ratings were related to the gender of the depicted vignette character and the nature of the portrayed behavior problems. Participants' own externalizing problems, social competence, and previous exposure to behavior problems in others related uniquely to adolescents' perceptions of the vignette characters. Overall, this study provided additional evidence that, although peers can serve as valuable informants, they also tended to reject adolescents who display behavior problems.

Title: Is Selective Mutism an Emotion Regulation Strategy for Children with Social Phobia? A Single Case Design Investigation.
Creator: Scott, Samantha, Beidel, Deborah, Rapport, Mark, Cassisi, Jeffrey, Hundley, Gulnora, University of Central Florida
Abstract / Description: To determine whether children with selective mutism (SM) withhold speech to regulate their emotional arousal and decrease automatic distress, the current study examines the behavioral and physiological responses of children with SM in comparison to children with social phobia (SP) and children with no psychiatric disorder (TD) as they participate in two social situations. A single case design strategy is used to compare behavioral and physiological responses both within and across groups....
Show moreTo determine whether children with selective mutism (SM) withhold speech to regulate their emotional arousal and decrease automatic distress, the current study examines the behavioral and physiological responses of children with SM in comparison to children with social phobia (SP) and children with no psychiatric disorder (TD) as they participate in two social situations. A single case design strategy is used to compare behavioral and physiological responses both within and across groups. Examining the temporal sequencing of behaviors and physiology provides a direct test of the utility of emotion regulation theory as it pertains to children with social phobia/selective mutism. The results indicate that children with SM show elevated arousal and emotional reactivity across all interaction segments relative to other children. Unique affective, behavioral and physiological responses occur between and within groups in relation to situational demands. The temporal sequencing of behavioral and physiological responses suggests that behavioral deficits may be related to underutilized and/or deficient physiological response systems and that not speaking represents a primitive avoidance strategy by children with SM to regulate extreme physiological arousal.

Title: Evaluating the utility of a virtual environment for childhood social anxiety disorder.
Creator: Wong, Nina, Beidel, Deborah, Rapport, Mark, Sims, Valerie, University of Central Florida
Abstract / Description: Objective: Two significant challenges for the dissemination of social skills training programs are (a) the need to provide sufficient practice opportunities to assure skill consolidation and (b) the need to assure skill generalization (i.e., use of the skills outside the clinic setting). In the case of social anxiety disorder, virtual environments may provide one strategy to address these issues. This investigation describes the development of an interactive skills-oriented virtual school...
Show moreObjective: Two significant challenges for the dissemination of social skills training programs are (a) the need to provide sufficient practice opportunities to assure skill consolidation and (b) the need to assure skill generalization (i.e., use of the skills outside the clinic setting). In the case of social anxiety disorder, virtual environments may provide one strategy to address these issues. This investigation describes the development of an interactive skills-oriented virtual school environment and evaluated its utility for the treatment of social anxiety disorder in preadolescent children (Study 1). This environment included both in-clinic and at-home solutions. In addition, a pilot replication/extension study further examined preliminary treatment efficacy between children who received a standard multi-component treatment and children who received the modified treatment with social skills practice in a virtual environment (Study 2). Method: Eleven children with a primary diagnosis of social anxiety disorder between 7 to 12 years old participated in the initial feasibility trial (Study 1). Five additional children participated in the replication/extension study (Study 2). To investigate preliminary treatment efficacy, clinical outcome measures for the Study 2 sample were compared to a comparison sample who received the standard treatment. Results: Overall, the virtual environment program was viewed as acceptable, feasible, and credible treatment components to children, parents, and clinicians alike but modifications would likely improve the current version. Additionally, although preliminary, children who received the modified treatment with virtual environment practice demonstrated significant improvement at post-treatment on clinician ratings but not parent or self-reported measures. Conclusion: Virtual environments are feasible, acceptable, and credible treatment components for clinical use. Future investigations will determine if the addition of this dose-controlled and intensive social skills practice results in treatment outcome equivalent to traditional cognitive-behavioral programs.
