Trait anxiety,anxious mood,and threat detection

Abstract

Subjects were required to detect either an angry or a happy target face in a stimulus array of 12 photographs. It was found with neutral distractor faces that those high in trait anxiety detected angry faces faster than did low trait-anxious subjects, but the two groups did not differ in their speed of detection of happy targets. In addition, high trait-anxious subjects detected happy target faces slower than low trait-anxious subjects when the distractor faces were angry. Comparable findings were obtained whether or not there was anxious mood induction. It was concluded that high trait-anxious individuals have facilitated detection and processing of environmental threat relative to low trait-anxious subjects, which enhance performance when the target is threatening, but which impair performance when the distractors are threatening.     

The stability of inhibited/uninhibited temperament from ages 3 to 11 years in mauritian children

Stability of inhibited/uninhibited temperament was assessed using 1,795 Mauritian children tested at ages 3, 8, and 11 years. Children were divided into uninhibited, middle, and inhibited groups at each age based on social behavior. Results indicated that, relative to uninhibited children (1) those inhibited at age 3 obtained larger inhibition scores at age 8 (p< .0001), (2) those inhibited at age 8 obtained larger inhibition scores at age 11 (p< .002), and (3) those remaining inhibited from ages 3 to 8 obtained larger inhibition scores at age 11 (p< .002). Relative to children who changed classification from ages 3 to 8, those remaining inhibited obtained larger inhibition scores (p< .05) and those remaining uninhibited obtained smaller inhibition scores (p< .015) at age 11. Inhibition scores tended to be higher in females by age 11. Results remained regardless of ethnicity. The results provide some support that inhibited/uninhibited temperament remains stable from ages 3 to 8 and may continue to age 11. The results suggest cross-cultural generalizability of these findings with implications regarding the development of anxiety disorders in the Mauritian population. The efforts of Cyril Dalais, Brian Bell, Athenea Chiriaca, and all the local members of the longitudinal study, the Mauritius Joint Child Health Project, are gratefully acknowledged. We are also especially thankful to Drs. Michael E. Dawson, David Walsh, and Bill McClure for their helpful comments and suggestions.The data used in this study were collected while the project was supported by the Medical Research Council (UK), the Wellcome Trust (UK), and the Mauritian government. The data were analyzed and findings written as part of the first author's dissertation work under the support of the NIMH Pre-doctoral Individual National Research Service Award and a USC Dissertation Fellowship Award.     

Personality correlates of self-appraised problem solving abilities

We examined the relations between the components of self-appraised problem solving abilities and personality constructs measured by a popular instrument. Results indicated that the Approach-Avoidance and Problem-Solving Confidence factors of the Problem Solving Inventory (PSI; Heppner, 1988) were significantly associated with the judging, perceiving, and feeling scales of the Myers-Briggs Type Indicator (Myers & McCaulley, 1985) among 112 undergraduates. Our results elucidate the relations between problem-solving appraisal, emotional predispositions, Willfulness, and preferences for structure. Implications for theoretical models of social problem solving and counselling interventions are discussed.     

USE OF TEXTURE FADING IN THE TREATMENT OF FOOD SELECTIVITY

Children with feeding disorders often display severe food selectivity. For many of these children, consuming highly textured foods may be aversive or potentially dangerous because of frequent gagging. The purpose of this study was to demonstrate the efficacy of texture fading in the treatment of food selectivity displayed by 4 children. Treatment involved the gradual addition of higher textures based on the results of periodic probes. In addition, food acceptance and swallowing were reinforced, while food refusal and food expulsion were placed on extinction. Results showed that all participants successfully advanced to consumption of age-appropriate texture and volume. The results suggest that texture fading with intermittent probes at higher textures may be an effective method for the treatment of food selectivity by texture.     

Using a Videogame Intervention to Reduce Anxiety and Externalizing Problems among Youths in Residential Care: an Initial Randomized Controlled Trial

Residential care is among the most intensive forms of treatment in youth care. It serves youths with severe behavioral problems and is primarily focused on targeting externalizing problems. Despite best efforts, effect sizes remain moderate, which may be due to the disregarding of internalizing symptoms – in particular anxiety - and to limitations regarding the delivery model of interventions. This initial randomized controlled trial (n?=?37) aimed to examine the effectiveness of a biofeedback videogame intervention (Dojo) as an addition to treatment as usual for youths with and without intellectual disability (ID) in residential care with clinical levels of anxiety and externalizing problems. Dojo targets both anxiety and externalizing problems, and incorporates the principles of conventional treatment, while addressing its limitations. Youths were randomly assigned to play Dojo (eight 30-min gameplay sessions) or to treatment as usual (TAU). Measurements of anxiety and externalizing problems were conducted at baseline, posttreatment, and 4-months follow-up through youths’ self-report and mentor-report. Completers-only analyses revealed decreases in self-reported anxiety and externalizing problems, and mentor-reported anxiety at posttreatment for participants in the Dojo condition compared to the control condition. Only mentor-reported anxiety was maintained at follow-up. No effect was found for mentor-reported externalizing problems. These findings provided preliminary evidence that Dojo is a promising, innovative intervention that engages high-risk youths. Practical implications are discussed.     

Effects of stress management and relaxation training on the relationship between diabetes symptoms and affect among Latinos

Objective: Stress management and relaxation (SMR) interventions can reduce symptoms of chronic disease and associated distress. However, there is little evidence that such interventions disrupt associations between symptoms and affect. This study examined whether SMR dampened the link between symptoms of hyperglycemia and proximal levels of affect. We predicted that during periods of increased hyperglycemia, individuals receiving SMR training, relative to controls, would demonstrate smaller increases in negative affect.

Design: Fifty-five adult Latinos with type 2 diabetes were randomised to either one group session of diabetes education (DE-only; N = 23) or diabetes education plus eight group sessions of SMR (DE + SMR; N = 32). After treatment, participants reported five diabetes symptoms and four affective states twice daily for seven days using a bilingual telephonic system.

Results: Mean age = 57.8 years, mean A1c = 8.4%, and ¾ was female with less than a high school education. Individuals receiving DE + SMR, compared to DE-only, showed a weaker positive within-person association between daily diabetes symptoms and nervous affect. Groups also differed on the association between symptoms and enthusiasm. Age moderated these associations in most models with older individuals showing less affect reactivity to symptoms.

Conclusions: Findings provide partial support for theorised mechanisms of SMR.     

Differences in Unit Cohesion and Combat-Related Mental Health Problems Based on Attachment Styles in US Military Veterans

This study explored the differences in perceived unit cohesion, trauma symptoms, depression symptoms, and anxiety symptoms controlling for childhood trauma, based on attachment style in US military veterans. Previous studies have reported that higher levels of military unit cohesion, bonding through the social relationships between service members and their larger units, and secure attachment, are negatively associated with trauma symptoms, depression symptoms, and anxiety symptoms in veterans. This study examined mental health distress symptoms as well as military unit cohesion across attachment styles. Results suggest mean differences in trauma symptoms, depression symptoms, and anxiety symptoms across attachment styles. However, there was no difference in perceived unit cohesion across the four attachment styles. Those using fearful-avoidant attachment styles reported the highest mean trauma, depression, and anxiety symptoms followed by those using a dismissing-avoidant attachment style. Those using a secure attachment style reported the least mean trauma, depression, and anxiety symptoms. Implications for assessing and treating avoidant type attachment styles are discussed.     

Autoregressive Generalized Linear Mixed Effect Models with Crossed Random Effects: An Application to Intensive Binary Time Series Eye-Tracking Data

As a method to ascertain person and item effects in psycholinguistics, a generalized linear mixed effect model (GLMM) with crossed random effects has met limitations in handing serial dependence across persons and items. This paper presents an autoregressive GLMM with crossed random effects that accounts for variability in lag effects across persons and items. The model is shown to be applicable to intensive binary time series eye-tracking data when researchers are interested in detecting experimental condition effects while controlling for previous responses. In addition, a simulation study shows that ignoring lag effects can lead to biased estimates and underestimated standard errors for the experimental condition effects.     

A Feasibility Trial of Mental Health First Aid First Nations: Acceptability,Cultural Adaptation,and Preliminary Outcomes

The Mental Health First Aid First Nations course was adapted from Mental Health First Aid Basic to create a community‐based, culturally safe and relevant approach to promoting mental health literacy in First Nations contexts. Over 2.5 days, the course aims to build community capacity by teaching individuals to recognize and respond to mental health crises. This feasibility trial utilized mixed methods to evaluate the acceptability, cultural adaptation, and preliminary effectiveness of MHFAFN. Our approach was grounded in community‐based participatory research principles, emphasizing relationship‐driven procedures to collecting data and choice for how participants shared their voices. Data included participant interviews (n = 89), and surveys (n = 91) from 10 groups in four provinces. Surveys contained open‐ended questions, retrospective pre‐post ratings, and a scenario. We utilized data from nine facilitator interviews and 24 facilitator implementation surveys. The different lines of evidence converged to highlight strong acceptability, mixed reactions to the cultural adaptation, and gains in participants’ knowledge, mental health first aid skill application, awareness, and self‐efficacy, and reductions in stigma beliefs. Beyond promoting individual gains, the course served as a community‐wide prevention approach by situating mental health in a colonial context and highlighting local resources and cultural strengths for promoting mental well‐being.     

Assessment of Current Genetic Counselor Practices in Post-Visit Written Communications to Patients

Providing patients with post-visit written communication (PVWC) is a long-standing component of genetic counseling. However the depiction of this practice in today’s clinical landscape is limited. To better describe this practice, we surveyed practicing clinical genetic counselors to ask if they send post-visit communications to patients and if so, what are the types, the average length, and the average time spent writing. They were also asked the perceived purpose of providing PVWC, if/how the practice has changed over time, and factors influencing the practice. Eighty three percent (233/280) of participants reported sending patients PVWC. Of those, 93% sent at least one communication written in patient-friendly language. The type of communication varied by specialty. Prenatal genetic counselors were less likely to send patient-specific letters and hybrid letters (defined as letters with content intended for both a physician and a patient) than those in cancer genetics (p = 0.010, p = 0.001, respectively) or pediatric genetics (p = 0.001, p = 0.004, respectively). Prenatal genetic counselors spent less time on average writing post-visit communications (19.0 min) relative to those in cancer and pediatric genetics (30.6 min, p = 0.027 and 37.7 min, p = 0.001, respectively). The most commonly cited purpose for sending PVWC was to provide patients a formal account of what happened during the appointment. These data suggest PWVC are still regularly sent to patients but the practice is variable and is influenced by numerous factors including specialty, years of experience, and time constraints.
