Suicidality Among Chronically Homeless People with Alcohol Problems Attenuates Following Exposure to Housing First 下载免费PDF全文

This study is the first to document suicidality among chronically homeless people with alcohol problems (N = 134) and examine its trajectory following exposure to immediate, permanent, low‐barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2‐year follow‐up. Baseline suicidal ideation was over four times higher than in the general population. Two‐year, within‐subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow‐up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2‐year follow‐up. 相似文献

Operant conditioning techniques were applied to the verbal behavior of three speech deficient children. Subjects A and B having no intelligible speech and Subject C having very little. Using candy and a puppet with a 13-yr-old boy (A), it was possible to condition vocalization rate. Using social reinforcement with a 6-yr-old boy (B), it was possible to extinguish animal-like sounds, to condition vocalization rate, and to shape a small vocabulary of syllables, but not to gain discriminative control over word emission. Using varied reinforcers, e.g., candy, praise, repetitions other own responses, and hand clapping with a 13-yr-old girl (C), it was possible to condition rate of verbalization, to establish appropriate mimicking, and to establish naming of five pictures. The results were consistent with the findings of Salzinger et al. (1965) and with those of Kerr et al. (1965). 相似文献

The present study suggests a method with which to assess the interrelations between different types of pretend play. In contrast to standard methods in this area, the various types of pretend play were measured within an interactive play scenario. The pretend play tasks were included in a semi‐structured play sequence and presented to young children between 24 and 30 months of age (N=30). Self‐ and doll‐directed pretence, object substitution, pretence with realistic objects, and self‐initiated pretend play, as well as the understanding that an object had been given two identities was tested. The capacity for dual representation was assessed by asking for the real and pretend identity of an object. Age differences were found in the overall score for elicited pretence but not for all items separately. Individual items also differed in difficulty and thus are of potential use for assessing intraindividual differences in pretend play. Findings are discussed in the context of current theories and methods concerning the development and assessment of pretend play. 相似文献

Research suggests that an overgeneral autobiographical memory style (i.e., retrieval of general memories when instructed to retrieve a specific episodic memory) represents a vulnerability marker for depression. Although adolescence is a period of high risk for the emergence of depression, little research has investigated the associations among overgeneral memory, psychopathology, and risk factors longitudinally in a community sample in this age group. We, therefore, investigated overgeneral memory, psychopathology (depression and anxiety), and rumination (an established risk factor for psychopathology) longitudinally in 269 typically-developing youth (125 females, 144 males) across 3 annual assessment points. We sought to determine whether 1) overgeneral memory would predict psychopathology across the entire sample, and 2) whether associations would vary as a function of longitudinal rumination growth. Across the entire sample, overgeneral memory did not predict psychopathology. For youth who reported elevated, and increasing, patterns of rumination over time, transient relationships between overgeneral memory and subsequent increases in anxiety were found. We conclude that overgeneral memory may represent a vulnerability marker for adverse psychological outcomes only for youth at risk for psychopathology. 相似文献

Stress regulation during pregnancy is considered to be connected to the timing of labour initiation. Although increasing knowledge is emerging on the regulation of parturition, there is currently no way to predict the start of spontaneous labour in women. The main aim of this study was to assess pain threshold and the sympathetic nervous system response to cold pain in relation to the onset of labour in healthy pregnant women. Ninety-three pregnant women were recruited and assessed for skin conductance (SC) activity during a cold pressor test in gestational week 38. Pain threshold and cold endurance were also measured and the results were compared with data obtained from hospital records. Seventy-four women had a spontaneous labour onset and a valid SC measurement. SC activity during the cold pressor test decreased significantly with the number of days left to spontaneous parturition. This may indicate a gradual decrease in sympathetic autonomic nervous system reactivity even during the last weeks of pregnancy. Measuring SC activity during mild stress provocation is a rapid and non-invasive means to study variation in sympathetic reactivity during pregnancy, and may be useful in research on stress regulation in pregnancy and its relation to labour initiation. 相似文献

BDNF regulates components of cognitive processes and has been implicated in psychiatric disorders. Here we report that genetic overexpression of the BDNF mature isoform (BDNF-tg) in female mice impaired working memory functions while sparing components of fear conditioning. BDNF-tg mice also displayed reduced breeding efficiency, higher anxiety-like scores, high self-grooming, impaired prepulse inhibition, and higher susceptibility to seizures when placed in a new empty cage, as compared with wild-type (WT) littermate controls. Control measures of general health, locomotor activity, motor coordination, depression-related behaviors, and sociability did not differ between genotypes. The present findings, indicating detrimental effects of life-long increased BDNF in mice, may inform human studies evaluating the role of BDNF functional genetic variations on cognitive abilities and vulnerability to psychiatric disorders. 相似文献

A favorable product country of origin (e.g., an automobile made in Germany) is often considered an asset by marketers. Yet a challenge in today's competitive environment is how marketers of products from less favorably regarded countries can counter negative country of origin perceptions. Three studies investigate how mental imagery can be used to reduce the effects of negative country of origin stereotypes. Study 1 reveals that participants exposed to country of origin information exhibit automatic stereotype activation. Study 2 shows that self‐focused counterstereotypical mental imagery (relative to other‐focused mental imagery) significantly inhibits the automatic activation of negative country of origin stereotypes. Study 3 shows that this lessening of automatic negative associations persists when measured one day later. The results offer important implications for marketing theory and practice.

Male-male competition can shape some behavioral or morphological traits of males. Here we investigate if this competition could play a role in the persistence of the polymorphism of handedness in human populations. A negative frequency-dependent selection mechanism has been hypothesized, based on the fact that left-handed men may benefit from a "surprise" advantage during fighting interactions because they are rare in human populations. This advantage may thereby enhance the probability of survival of left- handed men and/or their reproductive success through an increase in social status. In this study, we first explored the association between hand preference and lifetime fighting behavior in a population of 1,161 French men. No effect of hand preference on the probability of fighting was detected, suggesting that the innate propensity to fight does not differ between left- and right-handers. However, among men who had been involved in at least one fight during their lifetime, left-handers reported significantly more fights than right-handers. To explore the biological basis of this behavior, we also investigated the testosterone concentration in saliva samples from 64 French university students. Consistent with frequencies of fights, we found a significantly higher average testosterone concentration in left-handers than in right-handers. We suggest that these behavioral and hormonal differences may be acquired throughout life due to previous experiences in a social context and may favor the persistence of left-handers in humans. 相似文献
