Collateral Reports and Cross-Informant Agreement about Adult Psychopathology in 14 Societies

To advance international mental health assessment, instruments that have been internationally validated are needed. To this end, we analyzed ratings from 14 societies on the Adult Behavior Checklist (ABCL), a collateral-report form parallel to the Adult Self-Report (ASR; Achenbach and Rescorla 2003) for ages 18 to 59. Both the ABCL and the ASR assess problems, personal strengths, and adaptive functioning. For a sample of 8322 see note below collaterals, we found strong consistency across societies regarding which ABCL problem items tended to obtain relatively low, medium, or high ratings. Most societal effect sizes (ESs) for problem scale scores were small to medium (< 13.9 %), but the ES for the ABCL Personal Strengths scale was 25 %. For most of the same participants (N = 8,302), we analyzed cross-informant agreement between self-reports on the ASR and collateral reports on the ABCL. Cross-informant correlations for problem scale scores averaged .47, with considerable societal variation. Problem score means were higher on the ASR than the ABCL in every society, but the size of the difference varied across societies. Mean item ratings on the ABCL and ASR were highly correlated within every society (mean r = .92), but within-dyad item rating agreement varied widely in every society (mean r = .39). In all societies, non-corroboration of self-reported deviance and of collateral-reported deviance was common. Overall findings indicated considerable similarity but also some important differences in collateral-reported problems and adaptive functioning across 14 societies.     

Pragmatic Narratives of Hysterectomy Among Australian Women

Drawing on a qualitative study based on in-depth interviews with 30 rural and urban Australian women, we analyze their experiences of a hysterectomy for conditions other than cancer. Women were recruited via advertisements in community newspapers and the network sampling technique. The study aimed to identify the personal, social and medical factors that influenced their decision to undergo surgery and on their understandings of self following this procedure. Three common themes emerged: a negative response to a hysterectomy, ambivalence about it and a perceiving it as having a positive impact on the woman’s self. The latter pattern predominated, indicating that contrary to the medical rhetoric, women’s own accounts are different and relevant when counseling women about a hysterectomy.     

Quality of Life,Personality and Use of Pain Medication in Patients with Chronic Back Pain

The aim of the study was to assess whether the functional disability and the quality of life in patients with chronic back pain was associated with some personality traits and whether the use of pain medication in patients with chronic back pain can be predisposed with some personality traits. The study sample comprised 262 older patients with chronic back pain of non-inflammatory origin. The level of disability related to chronic back pain was assessed by Roland-Morris Questionnaire, health-related quality of life was assessed by Short Form 36 and personality traits by Eysenck Personality Questionnaire. Among analyzed personality traits (psychoticism, extraversion, neuroticism, lie tendencies), only neuroticism significantly predicted self-reported disability caused by back pain. Patients on pain medication had significantly worse quality of life and disability caused by back pain, but they did not differ significantly in personality traits compared to patients without pain medication. There were no differences in disability due to back pain and in level of neuroticism between patients who had jobs with higher or lower physical demand. People with higher scores on neuroticism inclined more to report a lower functional disability and the quality of life caused by chronic back pain. Patients on pain medication reported more inferior physical than psychological concept of quality of life. Use of pain medication was not associated with personality traits assessed by Eysenck Personality Questionnaire. In our elderly patients with chronic back pain, lower quality of life was associated with elevated neuroticism score and more frequent use of pain medication.     

External loading and maximum dynamic output in vertical jumping: the role of training history

We examined the effect of training history on the load-power relationship in vertical jumping (VJ) by employing external loads ranging from -30% to +30% body weight (BW). Based on previous findings, we hypothesized that (1) the maximum dynamic output (power production and momentum generation) would be within the tested loading interval, and (2) the load-power and load-momentum relations would depend on the subject's training history. Thirty-one healthy male subjects of different training history (i.e., 9 strength-trained athletes, 12 speed-trained athletes, and 10 sedentary individuals), performed maximum countermovement jumps on a force plate while a pulley system was used to either reduce or increase the subject's BW. An increase in external loading during VJ resulted in a systematic decrease (p<.001) in power production and momentum generation in all 3 studied groups. We also observed significant Group×Load interactions (p<.01) for the load-power and the load-momentum relationships, probably due to the group differences in slopes of the trend lines that describe the loading-associated changes in power and momentum. The results suggest that, from the evolutionary standpoint, the human muscular system of the lower limbs could be designed to produce the maximum power output against the loads that are well below the mass and inertia of the human body.     

Social Surrogacy and Adjustment: Exploring the Correlates of Having a “Social Helper” for Shy and Non-Shy Young Adolescents

A social surrogate is an individual who offers help and comfort in social situations or makes social events more exciting. In this study of 157 young adolescents (55% female; M_age = 13.84 years, SD = 0.75 years), the authors examined whether the linear and curvilinear associations between self-reported social surrogate use and adjustment outcomes (social problems, loneliness, anxiety symptoms, depressive symptoms) varied as a function of shyness and gender, after accounting for the effects of positive friendship quality. Regression analyses revealed that low and high levels of social surrogate use were related to greater social problems for all adolescents. In addition, shyness emerged as a moderator for several curvilinear effects. Specifically, results indicated that (a) high levels of social surrogate use were associated with greater anxiety for adolescents high in shyness; and (b) low levels of social surrogate use were associated with greater depressive symptoms for adolescents low in shyness. Findings highlight the developmental importance of specific types of relationship experiences during early adolescence and point to different implications of social surrogate use for shy and non-shy young adolescents.     

Shy children’s coping with a social conflict: The role of personality self-theories

Shy children’s risk for psychosocial difficulties may result partly from ineffective coping with social stressors. Little is known about which shy children are most susceptible to maladaptive coping styles. Personality self-theories may be one source of individual differences in shy children’s coping with social stressors. The purpose of this study was to examine whether the links between shyness and coping were moderated by personality self-theories. Participants were 175 children (M_age = 10.11 years), who completed self-report assessments of shyness, personality self-theories, and coping strategies. Self-theories moderated links between shyness and coping, sometimes differentially for boys and girls. For example, shyness was most strongly related to internalizing coping among entity-oriented children. However, shyness was most strongly negatively related to approach coping (social support, problem-solving) among incrementally-oriented boys and entity-oriented girls.     

Hippocampal Mek/Erk signaling mediates extinction of contextual freezing behavior

Fear memories elicit multiple behavioral responses, encompassing avoidance, or behavioral inhibition in response to threatening contexts. Context-specific freezing, reflecting fear-induced behavioral inhibition, has been proposed as one of the main risks factors for the development of anxiety disorders. We attempted to define the key hippocampal mediators of extinction in a mouse model of context-dependent freezing. Nine-week-old male C57BL/6J mice were trained and tested for contextual fear conditioning and extinction. Freezing behavior scored by unbiased sampling, was used as an index of fear. Proteomic, immunoblot, and immunohistochemical approaches were employed to identify, verify, and analyze the alterations of the hippocampal extracellular signal-regulated kinases 1 and 2 (Erk-1/2). Targeted pharmacological inhibition of the Erk-1/2 activating kinase, the mitogen activated and extracellular signal-regulated kinase (Mek), served to establish the role of Mek/Erk signaling in extinction. When compared to acquisition, extinction of contextual freezing triggered a rapid activation of Erk-1/2 showing a distinctive time-course, nuclear localization, and subcellular isoform distribution. These differences suggested that the upstream regulation and downstream effects of this pathway might be specific for each process. Dorsohippocampal injections of the Mek inhibitors U0126 (0.5 microg/site) and PD98059 (1.5 microg/site) immediately after the nonreinforced trials prevented Erk-1/2 activation and significantly impaired extinction. This effect was dissociable from potential actions on memory retrieval or reconsolidation. On the basis of these findings, we propose that hippocampal Mek/Erk signaling might serve as one of the key mediators of contextual fear extinction.     

Life event stress and the association with spontaneous abortion in gravid women at an urban emergency department.

In this study, the authors hypothesized that life event stress is associated with an increased risk of spontaneous abortion. Using a nested case-control design in an emergency department (N = 970), stress was measured using a life event inventory and a sample drawn from R. B. Ness et al.'s (1999) Early Pregnancy Study. Gestational age at time of fetal loss served as a marker of chromosomal status. Women experiencing more than one life event used more alcohol and public assistance. Spontaneous abortion at 11 weeks or greater was associated with more life event stress (adjusted odds ratio 2.9, 95% confidence interval 1.4-6.2), whereas spontaneous abortion at any gestational age was not, implying that life event stress increases the risk of chromosomally normal spontaneous abortion. An analysis of confounders showed tobacco use was associated with an increased risk of spontaneous abortion, whereas prenatal care was only associated with fetal loss at 11 weeks or greater.
