Acceptance and Commitment Therapy for generalized anxiety disorder in older adults: a preliminary report

Some evidence suggests that acceptance-based approaches such as Acceptance and Commitment Therapy (ACT) may be well-suited to geriatric generalized anxiety disorder (GAD). The primary goal of this project was to determine whether ACT was feasible for this population. Seven older primary-care patients with GAD received 12 individual sessions of ACT; another 9 were treated with cognitive-behavioral therapy. No patients dropped out of ACT, and worry and depression improved. Findings suggest that ACT may warrant a large-scale investigation with anxious older adults.     

The Moderating Effect of Anxiety on Development in Atypically Developing Toddlers

In typically developing children, researchers have found that anxiety disorders are associated with poorer intellectual abilities (Davis et al. Journal of Psychopathology and Behavioral Assessment 30:43–51, 2008). The aim of the current study was to examine the impact anxiety symptoms had on the developmental quotients of toddlers. A total of 170 toddlers ranging in age from 17 to 37 months were selected for inclusion in this study, all of whom were at risk for or had a developmental delay. Two factors indicative of behavioral symptoms of anxiety from the Baby and Infant Screen for Children with aUtIsm Traits-Part2 were utilized as the independent variables and the total developmental quotient from the Battelle Developmental Inventory, 2nd Edition was utilized for the dependent variable. Examination of results revealed that atypically developing toddlers with symptoms of anxiety had significantly lower developmental quotients when compared to toddlers without any anxiety symptoms. A discussion of the implications and limitations of this study are included.     

Modeling the Impact of Control on the Attractiveness of Risk in a Prospect Theory Framework

Many decisions involve a degree of personal control over event outcomes, which is exerted through one's knowledge or skill. In three experiments we investigated differences in decision making between prospects based on a) the outcome of random events and b) the outcome of events characterized by control. In Experiment 1, participants estimated certainty equivalents (CEs) for bets based on either random events or the correctness of their answers to U.S. state population questions across the probability spectrum. In Experiment 2, participants estimated CEs for bets based on random events, answers to U.S. state population questions, or answers to questions about 2007 NCAA football game results. Experiment 3 extended the same procedure as Experiment 1 using a within-subjects design. We modeled data from all experiments in a prospect theory framework to establish psychological mechanisms underlying decision behavior. Participants weighted the probabilities associated with bets characterized by control so as to reflect greater risk attractiveness relative to bets based on random events, as evidenced by more elevated weighting functions under conditions of control. This research elucidates possible cognitive mechanisms behind increased risk taking for decisions characterized by control, and implications for various literatures are discussed.     

Do intrusive memory characteristics predict depression at 6 months?

Two prospective studies have investigated whether the presence, intrusion, and avoidance of negative intrusive memories predict depression, and have reported conflicting findings. We aimed to replicate and extend these investigations by exploring the role of intrusion and avoidance of intrusive memories, as well as memory characteristics, in the prediction of depression prospectively. At Time 1 a mixed sample of community participants (N=85) were interviewed and completed self-report measures of depression, anxiety, and intrusive memory features. At Time 2 (6 months later, N=64) depression and anxiety symptoms were reassessed. Results were partly consistent with hypotheses for the sub-sample of participants who did not receive treatment between the baseline and follow-up assessments. Baseline levels of intrusion and some memory features (uncontrollability, distress, interference, numbness, detachment) predicted follow-up depression, controlling for baseline depression symptoms. Unexpectedly, avoidance of intrusive memories and other features (e.g., here and now quality) did not predict depression. Levels of intrusion and avoidance did not predict anxiety at follow-up. These results provide further evidence that intrusive memories are not simply an epiphenomenon of depression, but predict depression prospectively. Our results suggest that novel, depression-specific theories that emphasise the role of memory disturbances in the maintenance of depression are needed.     

Are community studies of psychological trauma's impact accurate? A study among Jews and Palestinians

We evaluated the accuracy of posttraumatic stress disorder (PTSD) and major depression (MD) diagnoses using brief assessment instruments conducted by phone. PTSD and MD were assessed by telephone interview in a randomly selected sample of Jewish and Palestinian residents of Jerusalem (N = 150) during a period of marked threat of terrorism and war. We utilized the PTSD Symptom Scale Interview Format (Foa, Riggs, Dancu, & Rothbaum, 1993) and the Patient Health Questionnaire-9 (PHQ-9; Kroenke, Spitzer, & Williams, 2001). We then conducted in-depth, in-person interviews within 2 weeks, assessing PTSD and MD using the Composite International Diagnostic Interview (CIDI; Kessler et al., 2004). The prevalence of PTSD and MD diagnosis ascertained by the 2 assessment modalities was similar. Indices of classification accuracy for the phone interview, using the in-person interview as the standard, ranged from modest to high. Brief phone and in-depth in-person measures of PTSD and MD also correlated similarly with other demographic, stress, and coping factors, suggesting convergent validity. Brief phone interviews appear useful for estimating the prevalence of psychological disorders in mass casualty contexts and may have a critical role in both epidemiologic work and guiding public health interventions.     

The School Adjustment of Rural Adolescents with and Without Disabilities: Variable and Person-Centered Approaches

This study examined the school adjustment of adolescents with disabilities and their nondisabled peers in a national sample of rural high school students. The total sample consisted of 7,376 students: 6,704 nondisabled students, 70 students with emotional and behavioral disorders (EBD), 512 students with learning disabilities (LD), and 90 students identified as English language learners (ELL). Teacher ratings on the Interpersonal Competence Scale-Teacher (ICS-T) were used to assess students’ adjustment on seven factors: academic, affiliative, aggressive, internalizing, popular, Olympian, and shy. Cluster analyses were used to identify distinct configurations of competence and risk separately for boys and girls. Differences between educational classifications were identified for the ICS-T factors and for the interpersonal competence configurations. Students with EBD were overrepresented in Multi-risk configurations (aggressive high-risk profiles), students with LD were overrepresented in both the Multi-risk and Disengaged (non-aggressive high-risk profiles) configurations, and students identified as ELL were overrepresented in Disengaged configurations.     

Anterior thalamic lesions alter both hippocampal-dependent behavior and hippocampal acetylcholine release in the rat

The anterior thalamic nuclei (ATN) are important for learning and memory as damage to this region produces a persistent amnestic syndrome. Dense connections between the ATN and the hippocampus exist, and importantly, damage to the ATN can impair hippocampal functioning. Acetylcholine (ACh) is a key neurotransmitter in the hippocampus, and in vivo measures of ACh are correlated to learning and memory performance. In the present study, complete lesions of the ATN impaired performance on two measures of hippocampal-dependent learning and memory (spontaneous alternation and delayed alternation) and severely disrupted behaviorally evoked ACh efflux within the hippocampus of adult male rats. In contrast, incomplete ATN lesions did not impair spontaneous alternation performance but did impair delayed alternation performance while blunting hippocampal ACh efflux. Interestingly, ATN lesions of any size did not affect basal concentrations of ACh in the hippocampus. These results demonstrate that the ATN have the capacity to modulate behaviorally relevant neuronal transmission within the hippocampus.     

The evolving vocabulary of the social sciences: the case of "socialization"

While the term "socialization" stands as a common and clearly understood term regularly used in social science and lay conversations alike, its history is complex. In the 19th century, socialization was introduced to refer to societal activities or projects, and only in the early 20th century did it gain usage as a term describing psychological processes transpiring within the individual. The architecture of the newer meaning harbored ambitions and problems of modern social science, including ideals of interdisciplinary theory and theoretic resolution of the individual/society dualism. Nevertheless, socialization became a central object of social scientific inquiry after World War II. This significant social scientific object was repeatedly altered: initially representing a vision of conforming citizens who were free from certain troubling characteristics depicted in psychoanalysis and well-suited to democracy, it later was engaged to create a vision of autonomous, resilient, and cognitively active actors able to negotiate a complex social world.     

The utility of the spatial span in a clinical geriatric population

Spatial Span subtest of the Wechsler Memory Scale has been viewed as an indicator of working memory and visuospatial processing. The current study examined the impact of cognitive impairment and its severity on Spatial Span performance. A neuropsychological battery including Spatial Span was administered to 538 individuals (65-89) who were grouped by consensus into Alzheimer's disease, Vascular Dementia, Amnestic Mild Cognitive Impairment, Non-Amnestic Mild Cognitive Impairment and cognitively normal. Increase in level of impairment resulted in a decrease in Spatial Span Total Score. A weak relationship between age and Spatial Span Total Score was found. Spatial Span Forward remains relatively stable regardless of level of impairment. Spatial Span Backward was more sensitive to severity. No significant differences were found between individuals diagnosed with Alzheimer's disease and those with Vascular Dementia suggesting similar deficit patterns in the cognitive abilities measured by the Spatial Span. Mild Cognitive Impairment groups and normals did not differ suggesting visuospatial processes are not affected early in the dementing process.     

The use of a mental imagery intervention to enhance integrated regulation for exercise among women commencing an exercise program

The purpose of this study was to examine the effects of a mental imagery intervention designed to enhance integrated regulation for exercise among women commencing an exercise program. Healthy women who previously did not exercise regularly (N?=?102; M _age ?=?29.54, SD?=?8.34) participated in an 8-week cardiovascular exercise program in which they exercised 3 times each week at a moderate intensity. The intervention group (n?=?51) received weekly guided imagery sessions which were administered in person via audio recording. A comparison group (i.e., attention control; n?=?51) received health information delivered in the same manner. Despite substantial dropout of participants from both groups, the analysis revealed that participants in the imagery group experienced greater changes in integration than participants in the comparison group. These findings support the utility of imagery interventions for influencing exercise-related cognitions, and more specifically integrated regulation.
