Efficacy of self-administered treatments for pathological academic worry: A randomized controlled trial

Research on treatments for reducing pathological worry is limited. In particular, academic worry is a common theme in generalized anxiety disorder (GAD) samples as well as non-clinical student samples. Given the high cost of anxiety disorders to society, research is needed to examine the efficacy of self-administered treatments designed to reduce pathological worry. The primary goal of this study was to investigate the benefits of three self-administered interventions for reducing academic worry. College students (N = 113) experiencing clinically significant academic worry were randomized to either: (a) worry exposure (WE); (b) expressive writing (EW); (c) relaxation consisting of pulsed audio-photic stimulation (APS); or (d) waitlist control (WLC). Participants were instructed to practice their interventions three times per week for one month and completed home practice logs online to track treatment adherence. Academic worry, general anxiety, and perceived stress were assessed at baseline and post-treatment. Academic worry and general anxiety were also assessed at a three-month follow-up. Those assigned to the WE and APS conditions showed significant improvement relative to EW and WLC at post-treatment. All treatment conditions showed continued improvement by follow-up, with no between-group differences. Treatment and public health implications are discussed.     

Comorbidity in youth with specific phobias: Impact of comorbidity on treatment outcome and the impact of treatment on comorbid disorders

The purpose of the present study was twofold. In an analysis of data from an existing randomized control trial of brief cognitive behavioral treatment on specific phobias (One-Session Treatment, OST; Ollendick et al., 2009), we examined 1) the effect of comorbid specific phobias and other anxiety disorders on treatment outcomes, and 2) the effect of treatment of the specific phobia on these co-occurring disorders. These relations were explored in 100 youth presenting with animal, natural environment, situational, and “other” types of phobia. Youth were reliably diagnosed with the Anxiety Disorders Interview Schedule for DSM-IV: Child and Parent versions (Silverman & Albano, 1996). Clinician severity ratings at post-treatment and 6-month follow-up were examined as were parent and child treatment outcome satisfaction measures. Results indicated that the presence of comorbid phobias or anxiety disorders did not affect treatment outcomes; moreover, treatment of the targeted specific phobias led to significant reductions in the clinical severity of other co-occurring specific phobias and related anxiety disorders. These findings speak to the generalization of the effects of this time-limited treatment approach. Implications for treatment of principal and comorbid disorders are discussed, and possible mechanisms for these effects are commented upon.     

Narrative exposure therapy for posttraumatic stress disorder in tortured refugees: A preliminary uncontrolled trial

Halvorsen, J.Ø. & Stenmark, H. (2010). Narrative exposure therapy for posttraumatic stress disorder in tortured refugees: A preliminary uncontrolled trial. Scandinavian Journal of Psychology 51, 495–502. Torture has severe mental health effects, especially in terms of posttraumatic stress disorder (PTSD) and depression. However, there is still a lack of empirical treatment studies. The present paper presents data on 16 torture survivors receiving 10 sessions of narrative exposure therapy (NET). Symptoms of PTSD and depression, assessed by Clinician‐Administered PTSD Scale (CAPS) and Hamilton Rating Scale for Depression (HRSD), decreased significantly from pre‐treatment to 6‐month follow‐up, with Cohen’s d effect sizes of 1.16 and 0.84, respectively. Although treatment gains were moderate, further research on evidence‐based treatments for PTSD and depression in refugee torture survivors is warranted.     

Chronic passive exposure to aggression escalates aggressiveness of rat observers

Previous studies have documented that exposure to aggression increases aggressiveness of human witnesses. However, the question of whether passive exposure to aggression can exclusively cause a risk of aggressive inclination for observers through a learning process, rather than mimicry effect, has not been readily addressed in the clinical literature. This study aimed to investigate this question by using a simple animal model to test the behavioral effect of chronic passive exposure to aggression. Our results indicate that observer rats that had been passively exposed to aggression for 10 min per day for 23 consecutive days exhibited more aggressive behavior than controls or those groups undergoing a single exposure to passive aggression. Furthermore, aggression levels in the group of 23‐day chronic exposure to aggression lasted 16 days after the recovery from exposure to aggression. These data suggest that the development of aggression in this model occurred through a learning process because only chronic exposure to aggression resulted in this behavioral outcome in the long run.

A cross-modal weapon focus effect: The influence of a weapon's presence on memory for auditory information

To examine whether a weapon's presence impairs witnesses' memory for auditory information (as it impairs memory for visual information), we conducted two experiments in which undergraduates watched one version of a videotape depicting a male target who held either a weapon or a neutral object and conversed with a female character. The semantic content of his remarks was either easy or difficult to comprehend. The weapon's presence did not affect voice identification accuracy or memory for the target's vocal characteristics (e.g., pitch, loudness, speech rate) but did worsen memory for semantic content in the Difficult Comprehension condition. Our results can be explained by multiple resource models of attention, which propose separate resource “pools” for different sensory modalities.     

Learning to like it: Aesthetic perception of bodies,movements and choreographic structure

Appreciating human movement can be a powerful aesthetic experience. We have used apparent biological motion to investigate the aesthetic effects of three levels of movement representation: body postures, movement transitions and choreographic structure. Symmetrical (ABCDCBA) and asymmetrical (ABCDBCA) sequences of apparent movement were created from static postures, and were presented in an artificial grammar learning paradigm. Additionally, “good” continuation of apparent movements was manipulated by changing the number of movement path reversals within a sequence. In an initial exposure phase, one group of participants saw only symmetrical sequences, while another group saw only asymmetrical sequences. In a subsequent test phase, both groups rated all sequences on an aesthetic evaluation scale. We found that posture, movement, and choreographic structure all influenced aesthetic ratings. Separate ratings for the static body postures presented individually showed that both groups preferred a posture that maximized spatial symmetry. Ratings for the experimental sequences showed that both groups gave higher ratings to symmetrical sequences with “good” continuation and lower ratings to sequences with many path reversals. Further, participants who had been initially familiarized with asymmetrical sequences showed increased liking for asymmetrical sequences, suggesting a structural mere exposure effect. Aesthetic preferences thus depend on body postures, apparent movement continuation and choreographic structure. We propose a hierarchical model of aesthetic perception of human movement with distinct processing levels for body postures, movements and choreographic structure.     

Evaluating the effect of educational media exposure on aggression in early childhood

Preschool-aged children (M = 42.44 months-old, SD = 8.02) participated in a short-term longitudinal study investigating the effect of educational media exposure on social development (i.e., aggression and prosocial behavior) using multiple informants and methods. As predicted, educational media exposure significantly predicted increases in both observed and teacher reported relational aggression across time. Follow-up analyses showed that educational media exposure also significantly predicted increases in parent reported relational aggression across more than a two year period. Results replicate and extend prior research that has demonstrated links between educational media exposure and relational aggression, but not physical aggression, during early childhood.     

Psychological consequences of collective violence in childhood: the case of Monterrey,Mexico / Consecuencias psicológicas de la violencia colectiva en la niñez: el caso de Monterrey,México

Abstract

During the last years, different types of violence have severely damaged Mexico. In this paper we examine the consequences that violence could have in children, one of the most vulnerable segments of society. In short, we predict that exposure to any type of violence will lead to higher depression and that this could be explained through the effects of violence on childhood well-being. Our hypothesis was supported in two studies, showing that exposure to street violence (Study 1, N = 607) and exposure to collective violence (Study 2, N = 172) can increase childhood depression. Moreover, in both studies, this effect was explained by the decrease of childhood well-being caused by violence exposure. The implications of these results are discussed.     

Direct and indirect effects of family violence on child-to-parent violence / Efectos directos e indirectos de la violencia familiar sobre la violencia filio-parental

Abstract

This study analyses the impact of family violence on adolescent maladjustment and child-to-parent violence in a community sample. It also explores a possible mediating effect of adolescent behavioural and/or emotional problems in the relationship between family violence and child-to-parent violence. The sample included 485 adolescents of both sexes, with an age range of 12 to 18 years. Two structural equation models are presented in the data analysis. The results support previous findings indicating that all forms of family violence appear to contribute to adolescent maladjustment. Moreover, indirect effects of family violence on child-to-parent violence through behavioural and emotional problems were found. The implications of these results are discussed.     

Treating PTSD in active duty service members using cognitive processing therapy or prolonged exposure therapy: Examining everyday practice at a military outpatient clinic

The Institute of Medicine has stressed the need for evaluations of evidence-based treatments (EBTs) for posttraumatic stress disorder (PTSD) among active duty service members (AD) using a variety of evaluation approaches (Institute of Medicine, 2012). The current study examined the clinical files of 134 service members who completed treatment for PTSD using either prolonged exposure (PE) or cognitive processing therapy at an outpatient clinic. At the completion of each session, therapists made a clinical rating as to whether or not the session was protocol adherent. The total number of treatment sessions and the proportion of sessions rated as being protocol adherent were calculated. Multi-level models estimated the change in patient PTSD and other psychological symptoms over time as a function of clinician-rated protocol adherence and total number of sessions. Approximately 65% of clinic encounters were rated by therapists as being protocol adherent. Significant reductions in PTSD and psychological symptoms were associated with protocol adherence, and this was particularly true for patients who began treatment above clinical thresholds for both PTSD and other psychological symptoms. However, as the number of sessions increased, the impact of protocol adherence was attenuated. Patient characteristics, including gender, ethnicity, and co-morbidity for other psychiatric disorders were not related to symptom change trajectories over time. These findings suggest that protocol adherence and efficiency in delivery of EBTs for the treatment of PTSD with AD is critical.
