Hair cortisol in relation to acute and post-traumatic stress symptoms in children and adolescents

Background: We report on the preliminary results of two independent studies that (1) compare the hair cortisol concentrations (HCC) of healthy controls with patients displaying post-traumatic stress symptoms (PTSS, study 1+2), (2) investigate whether pre-trauma HCC are predictive for the development of acute stress symptoms (ASS) and PTSS (study 1) and (3) determine whether HCC correlate with PTSS in a clinical sample of children (study 2).

Methods: In study 1, the clinical symptoms of 35 minors were examined one (T1) and seven weeks (T2) after surgery following an accident. Hair samples were taken after the accident that reflect cortisol secretion over the past three months before the accident (healthy controls). In study 2, HCC and PTSS symptoms were cross-sectionally assessed in 22 minors who had experienced a psychological trauma.

Results: The HCC of patients with PTSS were lower than the HCC of healthy controls (study 1+2). Secondary analyses showed that HCC were significantly lower in male PTSS patients than in male healthy controls, whereas the HCC in females were comparably low in both groups. Pre-trauma HCC did not predict the total ASS and PTSS scores (study 1) and HCC were not directly related to the total PTSS scores (study 2).     

Evaluating Treatments for Functionally Equivalent Problem Behavior Maintained by Adult Compliance with Mands During Interactive Play

A primary goal of behavioral interventions is to reduce dangerous or inappropriate behavior and to generalize treatment effects across various settings. However, there is a lack of research evaluating generalization of treatment effects while individuals with functionally equivalent problem behavior interact with each other. For the current study, the severe problem behavior of two participants with developmental disabilities was targeted for assessment and treatment. Results of a functional analysis indicated that for both participants, problem behaviors occurred when destructive behavior produced reinforcement of participant mands . The use of a multiple schedule that alternated between differential reinforcement of other behaviors and differential reinforcement of alternative behavior (mands) was sufficient to produce a significant reduction in problem behavior for one participant; the addition of differential reinforcement of alternative behaviors via compliance was necessary for the second participant. Extended treatment sessions, which focused on interaction between the two participants, involved one therapist concurrently implementing each participant’s treatment while they were directed to play with one another (a situation that previously evoked problem behavior). Results show that each participant’s treatment produced low to zero rates of problem behavior even during extended interactions.     

Factor solutions of the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) in a Swedish population

Culturally validated rating scales for social anxiety disorder (SAD) are of significant importance when screening for the disorder, as well as for evaluating treatment efficacy. This study examined construct validity and additional psychometric properties of two commonly used scales, the Social Phobia Scale and the Social Interaction Anxiety Scale, in a clinical SAD population (n?=?180) and in a normal population (n?=?614) in Sweden. Confirmatory factor analyses of previously reported factor solutions were tested but did not reveal acceptable fit. Exploratory factor analyses (EFA) of the joint structure of the scales in the total population yielded a two-factor model (performance anxiety and social interaction anxiety), whereas EFA in the clinical sample revealed a three-factor solution, a social interaction anxiety factor and two performance anxiety factors. The SPS and SIAS showed good to excellent internal consistency, and discriminated well between patients with SAD and a normal population sample. Both scales showed good convergent validity with an established measure of SAD, whereas the discriminant validity of symptoms of social anxiety and depression could not be confirmed. The optimal cut-off score for SPS and SIAS were 18 and 22 points, respectively. It is concluded that the factor structure and the additional psychometric properties of SPS and SIAS support the use of the scales for assessment in a Swedish population.     

Lifespan Development Revisited: African-Centered Spirituality Throughout the Life Cycle

Traditionally in the field of psychology, most theories were developed from the perspective of scholars from Western culture. Because of this, the generality of such theories is usually limited, especially when applying them to people of African descent who have experienced different realities of life as a function of worldwide racial oppression. Especially lacking in the theories is a consideration of the role of spirituality in the development and psychological well-being of people of African descent. The authors discuss the problems of Western theories using Erikson's model of life-span development as an example. They present the definition of spirituality using an African-centered lens, and then propose a synthesis between Western and non-Western developmental theories with the issue of spirituality placed in the center of analysis.     

Cognitive abnormalities and cerebral perfusion defects in a community-dwelling cohort of elderly men with MMSE within the normal range

Objectives: Mini Mental State Examination’s (MMSE’s) sensitivity in its upper level is questioned, hence we investigated cognitive abnormalities and defects in regional cerebral blood flow (rCBF) in elderly with MMSE scores ≥24.

Methods: One hundred and four men at age 81 with MMSE scores ≥24 (mean 28.4 ± 1.7), no dementia or stroke, were examined with neuropsychological test battery, and their rCBF was estimated using ^99mTc-HMPAO SPECT.

Results: MMSE was very sparsely correlated with rCBF. Instead, visuo-spatial tests were correlated with rCBF in parietal and occipital lobe, verbal tests with rCBF in frontal and temporal-parietal lobes, and most of all between Digit Symbol and all rCBF regions, especially in subcortical gray and white matter. In a cluster of low achievers, test of Synonyms, followed by Digit Symbol and Benton test, had highest discriminatory importance. Low achievers had generalized rCBF changes especially in subcortical areas. Only lower scores on two MMSE items, figure drawing and calculation, could discriminate the clusters.

Conclusion: A substantial number of octogenarian men with MMSE ≥ 24p have widespread rCBF changes corresponding to a decreased speeded performance and verbal capacity.     

Insight in frontotemporal dementia: conceptual analysis and empirical evaluation of the consensus criterion "loss of insight" in frontotemporal dementia

The objective of this study was to suggest a new formulation of the core research diagnostic consensus criterion "loss of insight" in frontotemporal dementia (FTD). Eight patients with FTD (diagnoses made by interviews, medical and neuropsychological examination, CT scan, and regional cerebral glucose metabolism measured by positron emission tomography (PET) participated in the study). The results indicated that insight was present in three out of eight patients, and that insight appears to be a heterogeneous concept. Two types of insight emerged: Emotional insight associated with frontotemporal functions, and cognitive insight, related to posterior cognitive functions. These results suggest that loss of insight should not serve as a core criterion on FTD, but serves well as a supportive criterion of the disease.     

Body images of patients with anorexia nervosa, bulimia nervosa and female control subjects: a comparison with male ideals of female attractiveness

Body images of female patients with anorexia nervosa and bulimia nervosa were assessed against females without eating disorders and compared with male ideals of female attractiveness. A computer program was applied to examine body images of 62 patients with anorexia nervosa, 45 patients with bulimia nervosa, and 40 female and 39 male control subjects. Body size overestimation was most distinct in the two patient groups. Self-ideal discrepancy was highest in bulimia nervosa. Estimation of the society's ideal female body in all three female groups did not differ from men's perception of the most attractive female body. Congruence of ideals of female attractiveness in patients, female, and male control subjects and described differences between patients and female controls support the theory that body image disturbance is a problem of processing self-referential information regarding body image rather than a problem of processing body image related information per se.     

Mary Wollstonecraft's Feminist Critique of Property: On Becoming a Thief from Principle

The scholarship on Mary Wollstonecraft (1759–1797) is divided concerning her views on women's role in public life, property rights, and distribution of wealth. Her critique of inequality of wealth is undisputed, but is it a complaint only of inequality or does it strike more forcefully at the institution of property? The argument in this article is that Wollstonecraft's feminism is partly defined by a radical critique of property, intertwined with her conception of rights. Dissociating herself from the conceptualization of rights in terms of self‐ownership, she casts economic independence—a necessary political criterion for personal freedom—in terms of fair reward for work, not ownership. Her critique of property moves beyond issues of redistribution to a feminist appraisal of a property structure that turns people into either owners or owned, rights‐holders or things acquired. The main characters in Wollstonecraft's last novel—Maria, who is rich but has nothing, and Jemima, who steals as a matter of principle—illustrate the commodification of women in a society where even rights are regarded as possessions.     

Does the experience of presence restore self-control?

A wide range of research suggests that the exertion of self-control is a limited resource or constrained by a motivational shift. Less attention, however, has been given to the question how self-control capacity can be restored. This study examined whether this restoration can be achieved by “presence,” the perceptual illusion of non-mediation. We suggest that the adoption of the mediated reference systems creates a “holiday from self” and restores self-control capacity. Depleted participants who saw an immersive video clip performed better in a subsequent self-control task than participants who saw a non-immersive video clip or were in a waiting group. But the concrete mechanism remains open: Self reported presence did not serve as a mediator.     

Identity status measurement across contexts: variations in measurement structure and mean levels among White American, Hispanic American, and Swedish emerging adults

We conducted this study to examine measurement equivalence and mean differences in identity status across 3 ethnic/cultural contexts: White American, Hispanic American, and Swedish. We used the Extended Objective Measure of Ego Identity Status II (EOM-EIS-II; Bennion & Adams, 1986), a commonly used instrument in the identity status literature. We conducted analyses to ascertain the extent to which the EOM-EIS-II functioned equivalently in 3 ethnically/culturally different samples. The internal structure of the measure was consistent across contexts. When we statistically controlled effects of age and gender, mean differences tended to be largely cross-cultural at the observed level of analysis but to be both cross-ethnic and cross-cultural at the latent level of analysis. This divergence in findings was found despite the limited age range represented in each of the samples. We therefore concluded that measurement error may have played a role in these differences and that data gathered using the EOM-EIS-II should be analyzed using latent variable methods. We discuss results in terms of using the EOM-EIS-II with diverse populations.
