Examining the initial usability,acceptability and feasibility of a digital mental health intervention for college students in India

Generalised anxiety disorder (GAD) is prevalent among college students in India; however, barriers like stigma, treatment accessibility and cost prevent engagement in treatment. Web- and mobile-based, or digital, mental health interventions have been proposed as a potential solution to increasing treatment access. With the ultimate goal of developing an engaging digital mental health intervention for university students in India, the current study sought to understand students' reactions to a culturally and digitally adapted evidence-based cognitive behavioural therapy (CBT) for GAD intervention. Specifically, through theatre testing and focus groups with a non-clinical sample of 15 college students in India, the present study examined initial usability, acceptability and feasibility of the “Mana Maali Digital Anxiety Program.” Secondary objectives comprised identifying students' perceived barriers to using the program and eliciting recommendations. Results indicated high usability, with the average usability rating ranking in the top 10% of general usability scores. Participants offered actionable changes to improve usability and perceived acceptability among peers struggling with mental health issues. Findings highlight the benefits of offering digital resources that circumvent barriers associated with accessing traditional services. Results build on existing evidence that digital interventions can be a viable means of delivering mental healthcare to large, defined populations.     

Virtual reality goes to war: a brief review of the future of military behavioral healthcare

Numerous reports indicate that the incidence of posttraumatic stress disorder (PTSD) in returning OEF/OIF military personnel is creating a significant healthcare challenge. These findings have served to motivate research on how to better develop and disseminate evidence-based treatments for PTSD. Virtual Reality delivered exposure therapy for PTSD has been previously used with reports of positive outcomes. This article details how virtual reality applications are being designed and implemented across various points in the military deployment cycle to prevent, identify and treat combat-related PTSD in OIF/OEF Service Members and Veterans. The summarized projects in these areas have been developed at the University of Southern California Institute for Creative Technologies, a U.S. Army University Affiliated Research Center, and this paper will detail efforts to use virtual reality to deliver exposure therapy, assess PTSD and cognitive function and provide stress resilience training prior to deployment.     

A Case of Premature Termination in a Treatment for Generalized Anxiety Disorder

In this paper we present a case of failure in an integrative treatment for generalized anxiety disorder (GAD) combining cognitive-behavioral therapy, an empirically supported treatment for GAD, and interpersonal-emotional processing therapy. The client of focus dropped out of treatment after the eighth session. Based on our analysis of this case, we discuss the participant, technical and relationship factors that were likely implicated in this case of premature termination in both of the cognitive-behavioral and interpersonal-emotional processing segments that comprised the treatment. Implications for practice, training and future research are also discussed.     

Context fear learning specifically activates distinct populations of neurons in amygdala and hypothalamus

The identity and distribution of neurons that are involved in any learning or memory event is not known. In previous studies, we identified a discrete population of neurons in the lateral amygdala that show learning-specific activation of a c-fos-regulated transgene following context fear conditioning. Here, we have extended these studies to look throughout the amygdala for learning-specific activation. We identified two further neuronal populations, in the amygdalo-striatal transition area and medial amygdala, that show learning-specific activation. We also identified a population of hypothalamic neurons that show strong learning-specific activation. In addition, we asked whether these neurons are activated following recall of fear-conditioning memory. None of the populations of neurons we identified showed significant memory-recall-related activation. These findings suggest that a series of discrete populations of neurons are involved in fear learning in amygdala and hypothalamus. The lack of reactivation during memory recall suggests that these neurons either do not undergo substantial change following recall, or that c-fos is not involved in any such activation and change.     

The Level of Detail in Infants' Word Learning

ABSTRACT— This article summarizes recent findings on infant word learning and recognition. Infants initially store very detailed representations of words, including details that are not truly necessary for word recognition. As they are exposed to more varied productions of words, they develop more sophisticated knowledge about which details are important, and streamline their representations, allowing them to better recognize words across different contexts, speakers, and environments.     

Peer Experiences of Anxious and Socially Withdrawn Youth: An Integrative Review of the Developmental and Clinical Literature

Prior research indicates that both anxious youth and socially withdrawn youth tend to experience challenges and difficulties in various aspects of their peer relationships and social functioning. While clinical psychology researchers have examined how anxiety relates to peer experiences using normative and clinically anxious samples, developmental psychologists have focused primarily on the peer experiences of shy and withdrawn children. Research from these two fields has progressed on related yet separate paths, producing similar results despite using different terminology and assessment techniques. The purpose of this review is to bring together the developmental and clinical bodies of literature on the peer experiences of anxious and socially withdrawn youth by identifying common themes and unique contributions of each discipline. Studies reviewed focus specifically on the peer constructs of acceptance, friendship, peer victimization, social skills, and social-cognitive processes. Limitations including methodological inconsistencies and insufficient examination of age-, gender-, and ethnicity-related issues are identified. Recommendations for future collaborations between developmental and clinical researchers as well as implications for interventions targeting the peer relations of anxious and withdrawn youth are discussed.     

Memory for noun pairs in the same or different underlying strings

A number of studies have shown that children learn noun pairs faster when they have been presented in a noun-verb-noun context than when they are presented in a noun-conjunction-noun context. Suzuki and Rohwer (1969) hypothesized that the underlying strings of sentences correspond to memory units, making it easier to recall two nouns from the same underlying string than from two different underlying strings. They reported that data from fifth graders supported this hypothesis but that data from college students did not. The experiments reported here were done to determine whether the hypothesis would be supported (a) if the test rate were faster than that used by Suzuki and Rohwer or (b) if sentences longer and more complex than those used by them were employed. The recall data accorded with some predictions derived from the hypothesis. However, data from Ss’ posttraining reports on how they learned the pairs suggest that Ss, particularly adults, often made up their own strings rather than using those provided, and raise the question of the adequacy of Suzuki and Rohwer’s procedure for testing this hypothesis, particularly in adults.     

A Primer Of Closed Head Injury Sequelae In Post-Traumatic Stress Disorder

Abstract

By definition, an individual diagnosed with post-traumatic stress disorder (PTSD) has been exposed to a serious threat of physical harm that engenders concomitant feelings of fear, helplessness, or horror (American Psychiatric Association, 1994). According to the current diagnostic taxonomy, PTSD may develop when the person witnesses harm against someone else or learns of harm occurring to an intimate other. Yet, all too often, PTSD is associated with the direct experience of physical injury through assault, accident, or other violence. As such, individuals with PTSD are at increased risk of having sustained a head injury, particularly during the traumatic events that elicited the PTSD symptoms (Knight, 1996). Consistent with this assertion, there are indications that individuals who sustain a head injury are increasingly likely to develop subsequent PTSD (Bryant & Harvey, 1998; Chemtob et al., 1998), with the prevalence of PTSD in this population estimated to be as high as 30% (Bryant & Harvey, 1996). Moreover, among people with PTSD, those who have sustained head injuries are apt to have more severe symptoms than those who have not (Chemtob et al., 1998).
