Psychosocial histories, social environment, and HIV risk behaviors of injection and noninjection drug using homeless youths.

Injection drug use is a common risk behavior for HIV infection among homeless, runaway and street youths. However, the psychosocial histories and current social environment of these youths are not well understood. The authors recruited 186 homeless, runaway and street youths using systematic street-based sampling methods, and assessed psychosocial histories, current daily activities, and sexual and drug-related risk behaviors using qualitative and quantitative techniques. Youths reported high lifetime rates of injection drug use (45%), recent drug and alcohol use (100%), and current homelessness (84%). Injection drug using youths were more likely than noninjection drug using youths to report traumatic psychosocial histories, including parental substance use and forced institutionalization, use of alcohol and other noninjection drugs, a history of survival sex, and the use of squats or abandoned buildings as shelter. These findings underscore the need for multifaceted service and prevention programs to address the varied needs of these high-risk youths.

Effect of the social environment on alcohol involvement and subjective well-being prior to alcoholism treatment.

This article describes a conceptual model developed to explain abusive use of alcohol and reports results of an initial test of that conceptualization. General social support is hypothesized to affect the level of subjective well-being, while alcohol-relevant social support affects the degree of alcohol involvement. A cross-sectional test of two models derived from this formulation was made using data from 148 alcoholic clients entering treatment at a private non-profit psychiatric facility. Results indicate that a model in which no direct relationship between alcohol involvement and subjective well-being is specified provides a more parsimonious explanation of interrelationships at the time of treatment entry. Alcohol involvement is explained by alcohol-relevant affiliative and instrumental support (albeit weakly), and subjective well-being is explained by general affiliative and instrumental social support. There is virtually no interrelationship between alcohol involvement and subjective well-being once the support variables are taken into account. The findings indicate that treatment should more often incorporate others from a client's social network, using significant others first to provide general social support and later alcohol-relevant support as well. Further analyses involving samples with more heterogeneity in levels of social investment and exploring the utility of these variables for treatment matching categorization decisions are warranted.

Psychosis, migration and social environment: an age--and--gender controlled study.

PURPOSE: Adverse social experiences are frequently invoked to explain the higher rate of psychosis among migrant groups. The aim of the present study was to establish the socio-environmental factors distinguishing migrant psychotic patients from autochthonous patients. SUBJECTS AND METHOD: We conducted a cross-sectional survey involving 341 migrant psychotic patients matched for age and gender with 341 autochthonous psychotic patients. RESULTS: Migrant patients lived more often with their parental family, were less often enrolled with a referral psychiatrist, presented a lower rate of employment, a lower percentage of alcohol misuse and of suicide attempts. DISCUSSION: Our findings add to the growing body of results showing that more attention needs to be focused on socio-environmental variables in psychosis research. However, several limitations have to be taken into account, particularly with regard to selection biases and age of onset of the psychotic illness. CONCLUSION: Our results are compatible with the hypothesis that unemployment is a contributing factor in the risk for psychosis among migrant groups. Migrants' families are an important keystone in the mental health care process of their sick relatives. Our service models need to be adapted with the aim to make the treatment easier for migrant patients.

[Social environment and morpho-physiological status of young males in the fall groups of great gerbil (Rhombomys opimus Licht). Effect of adults' presence].

The dependence of stress and sex hormone levels, size of mid-ventral skin gland, and body mass of young males on the presence in social groups of adult gerbils (>1 year old) were studied during the fall of 1999 in the non-breeding high density population of the great gerbil (Rhombomys opimus Licht; Bukhara region, Uzbekistan). Contents of corticosterone and testosterone in fecal samples collected from young males in the field were analyzed by non-invasive radioimmunoassay. The fall gerbil groups with adults were of larger size than those without adults. The total number of individuals in a group is positively correlated with concentration of corticosterone in feces of young males. Presence of adult male and especially of adult female suppresses maturation of juvenile males indicated by size of the androgene-dependent mid-ventral gland, but accelerates their total growth. Thus, the social environment influences morpho-physiological characters of young males, effecting rate of their maturation directly or indirectly through the density dependent stress.

Influence of photoperiod and social environment on sexual maturation in female deer mice (Peromyscus maniculatus bairdii).

Female deer mice (Peromyscus maniculatus) were reared on either a long photoperiod (15:9 hr light/dark) or on short days (8:16 hr light/dark) from birth. Beginning at weaning, females were housed with an adult male, with an adult female, or in social isolation. In the first experiment, vaginas opened more slowly in females on short days than in those on long days. Vaginal introitus was also retarded in females reared with an adult female in comparison with females reared in isolation. When examined at 37 days of age, females reared with an adult male had larger uteri than those reared alone; uteri were also larger in long-day than in short-day females. In Experiment 2, females were killed at 30 days of age; again, uterine growth was stimulated by exposure of young females to either long days or an adult male. As was previously demonstrated for male deer mice, sexual maturation in females is regulated by photoperiod and social cues. Heterospecific social stimuli accelerate maturation in individuals that otherwise would be inhibited by having been reared on a short photoperiod.

Social environment moderates the association between catastrophizing and pain among persons with a spinal cord injury.

Catastrophizing, or exaggerating the negative consequences of a situation, is associated with higher pain intensity, emotional distress, and functional disability among persons with chronic pain. According to the 'communal coping' model, catastrophizing in persons with pain may function as a social communication directed toward obtaining social proximity, support, or assistance. We tested the hypothesis, based on this model, that social factors would moderate the association between catastrophizing and sensory and affective pain. Seventy-four persons with a spinal cord injury and chronic pain completed measures of catastrophizing, solicitousness, depression, and sensory and affective pain before beginning a randomized controlled medication trial. Catastrophizing was significantly associated with solicitousness and pain reports. The association between catastrophizing and sensory pain scores was stronger for those who lived with a spouse or partner than for those who lived with someone else. In addition, there was a stronger association between catastrophizing and affective pain for those who reported greater solicitousness in their relationship. The results provide partial support for the communal coping model of catastrophizing.

Cognitions, coping and social environment predict adjustment to phantom limb pain.

Biopsychosocial models of chronic pain hypothesize a role for psychological and environmental factors in adjustment to chronic pain. To test the utility of such models for understanding phantom limb pain, 61 persons with recent amputations were administered measures of average phantom limb pain intensity, pain interference, depression, pain coping use, pain cognitions and appraisals, and social environmental variables 1 month post-amputation, and the measures of pain intensity, pain interference, and depression again 5 months later. Multiple regression analyses showed that the psychosocial predictors made a statistically significant contribution to the concurrent prediction of average phantom limb pain, pain interference, and depression at the initial assessment, and a significant contribution to the prediction of subsequent change in pain interference and depression over the course of 5 months. The results support the utility of studying phantom limb pain from a biopsychosocial perspective, and identify specific biopsychosocial factors (e.g., catastrophizing cognitions, social support, solicitous responses from family members, and resting as a coping response) that may play an important role in adjustment to phantom limb pain.

Early social environment interferes with the development of NADPH-diaphorase-reactive neurons in the rodent orbital prefrontal cortex.

The influence of early parental deprivation on the development of NADPH-diaphorase-(NO-synthase) reactive neuron numbers in subregions of the orbital prefrontal cortex (ventrolateral orbital, lateral orbital, and agranular insular cortex) was quantitatively investigated in the precocious lagomorph Octodon degus. Forty-five-day-old degus from three groups were compared: (1) repeated parental separation: degus that were repeatedly separated from their parents during the first three postnatal weeks and thereafter raised in undisturbed social conditions; (2) chronic isolation: degus that were raised under undisturbed social conditions until postnatal day 21, and then were reared in chronic social isolation; and (3) control: degus that were reared undisturbed in their families. Compared to the control animals the ventrolateral orbital prefrontal cortex and agranular insular cortex of the two deprived groups displayed significantly decreased density of NADPH-diaphorase-reactive neurons (down to 62% in the ventrolateral orbital prefrontal cortex of males, 70% in the agranular insular cortex, and in the lateral orbital prefrontal cortex 80% in both genders). These results confirm that early changes of social environment interferes with the development of limbic circuits, which might determine normal or pathological behaviors in later life.

Writing characteristics of suicidal people on the Internet: a psychological investigation of emerging social environments.

Three studies were carried out to investigate the writings of suicidal people on the Internet, hypothesizing consistent findings to equivalent research of offline writing. In Study 1, suicidal persons' (n = 34) attributions as the cause of their condition, as expressed in their free online writing, were compared to those of emotionally distressed, nonsuicidal (n = 16) and to nondistressed (n = 15) individuals. Results showed that suicidal persons have significantly more stable and global attributions than do the other groups. In Study 2, expressions of self-focus in online written messages were compared among suicidal, two levels of nonsuicidal but distressed, and nondistressed individuals (200 messages in each group). With the use of various expressions of self-focus, findings showed that suicidal people were distinctively self-focused in their writing, unlike their counterparts. In Study 3, psychologically relevant themes in the online writing of suicidal (n = 39) and highly distressed, nonsuicidal persons (n = 24) were compared. Results revealed that the former expressed significantly more unbearable psychological pain and cognitive constriction than did the latter. The findings of the three studies are consistent with those found in examinations of offline writing. The research has important implications for the use of online environments for psychological research and means for assessment, as well as for understanding suicidality.
