[The modification of the intraspecific behavior of male rats raised in isolation with different variants of interaction with related animals].

It was found that intraspecific behaviour of male rats having been transformed in consequence of breeding under the conditions of social isolation could be modified afterwards by an experience of social contacts. Long-term keeping the isolatedly bred rats with their mates in adulthood decreases the level of intraspecific sociability but does not affect the relatively high level of aggression of the animals under study. On the contrary, the short-term periodic social contacts with the mates in a situation of competition for water decrease only the level of aggression but not that of intraspecific sociability. However, in any case the transformations of the species-typical ritual of aggressive behaviour in consequence of early isolation are steady and are not corrected by later social contacts.

Love, self-esteem, and multiple sclerosis.

Multiple sclerosis (MS) is a progressive chronic disease which generally appears in early adulthood. The debilitating symptoms of MS can have adverse effects on the sufferer's self-esteem, a vital coping resource for sufferers of chronic diseases. This study explores the effects of positive affect and social isolation--conceived broadly together as love--on self-esteem. We found that love was the most powerful predictor of self-esteem, followed by attitude stage, number of years since diagnosis, social class, and physical restriction.

The effects of successful intervention on quality of life in patients with varying degrees of lower-limb ischaemia.

OBJECTIVES: to assess the quality of life after successful intervention among patients with varying degrees of lower-limb ischaemia in comparison with healthy controls and the respondents>> degree of sense of coherence. MATERIALS AND METHODS: one hundred and twelve patients and 102 healthy controls were assessed for quality of life (Nottingham Health Profile) and sense of coherence. MAIN RESULTS: successful angioplasty or surgical intervention led to an improved quality of life at 6 months, in particular with regard to pain, sleep, physical mobility, hobbies and holiday and to a level similar to healthy controls in sleep, social isolation, paid employment and family relationships. It remained at a significantly lower level than that of healthy controls with regard to pain, emotional reactions, physical mobility, energy, housework, hobbies, holidays, sex and social life. Critical ischaemia patients did not reach the same level of quality of life as the claudicants or the healthy controls. CONCLUSION: successful treatment for chronic limb ischaemia improved the quality of life significantly, more so in claudicants than in patients with critical ischaemia. The degree to which the quality of life improved was associated with the patients>> sense of coherence and their ankle pressure.

Disrespect and isolation: elder abuse in Chinese communities.

Based on a qualitative study of home care workers, this paper aims to understand elder abuse of Chinese Canadians. The findings show disrespect is the key form elder abuse takes in the Chinese community. As a culturally specific form of abuse, disrespect remains invisible under categories of elder abuse derived from a Western cultural perspective. Applying a social exclusion framework to understand the dynamic of elder abuse, we argue that as a marginalized racial minority immigrant, an elderly Chinese person's vulnerability to abuse is increased under conditions of social isolation.

Effects of morphine on different aspects of social play in juvenile rats.

To clarify the influence of opioids on social play, the effects of morphine on playful and non-playful social behavior in juvenile rats was investigated under different conditions. Environmental variables employed were different (dim and intense) levels of illumination during testing, familiarity to the test cage, and different periods of social isolation prior to testing. Under dim light conditions, morphine markedly increased playful social behavior, such as pinning, boxing/wrestling and following/chasing, whereas non-playful social behavior such as social exploration and contact behavior was hardly affected. This effect of morphine was independent of duration of previous isolation and dose-dependent, with a maximal effect at 1.0 mg/kg. The mechanism of this effect is interpreted as an action on the rewarding aspects of play. A dose of 0.1 mg/kg of morphine abolished the initial suppression of play induced by unfamiliarity to the test cage, without influencing total levels of play. This may be an effect of morphine on the integration of sensory stimuli. Under intense light conditions, whereas playful behavior was completely suppressed, morphine itself hardly affected such behavior, but decreased some aspects of non-playful social behavior. These results suggest that in juvenile rats playful and non-playful forms of social behavior are differentially regulated. In addition, opioid systems may be involved at different levels in the regulation of social play.

Psychological response of children to isolation in a protected environment.

A behavioral observation study of 14 children with cancer treated in a laminar airflow protected environment (PE) unit was done over a period of 2 years. A total of 3629 observations were completed, and results related to perception, sleep, intellectual functioning, physical discomfort, mood, management problems, activity patterns, social-communicative behavior, and sedation are reported. In general, despite evidence from the literature that sensory deprivation and social isolation can cause severe disturbance of the sensory apparatus, no debilitating or long-term psychological effects related to prolonged PE treatment were noted. The differences between PE and deprivation-isolation contexts are discussed, and the need for psychosocial support of these patients is emphasized.

Rat pup isolation calls are reduced by functional antagonists of the NMDA receptor complex.

Compounds that reduce ion flux through N-methyl-D-aspartate (NMDA) coupled cation channels were evaluated for their effects on rat pup ultrasonic vocalizations (USV). Previous studies have demonstrated that rat pups emit ultrasonic calls during social isolation and that several classes of anxiolytics decrease, while putative anxiogenics increase, the number of these calls. The competitive NMDA antagonists 2-amino-7-phosphonoheptanoic acid (AP-7) and (+/-)-3-(2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid [+/-)-CPP) as well as a partial agonist at the strychnine-insensitive glycine receptor, 1-aminocyclopropanecarboxylic acid (ACPC), reduced USV at doses that did not affect either motor activity or core temperature. A dose of glycine sufficient to elevate hippocampal glycine concentrations by 85% antagonized the effects of ACPC, but not AP-7. Glycine alone did not alter USV, but NMDA when given by itself increased USV by almost 50% at subconvulsant doses. Moreover, a dose of NMDA that did not affect USV antagonized the effects of AP-7 but not ACPC. Taken together, these findings are consistent with previous studies using conflict procedures which indicate that agents which reduce activity at NMDA receptor coupled cation channels may constitute a new class of anxiolytic agents.

Bosnian refugees and the stressors of exile: a narrative study.

The authors used semistructured interviews to examine exile-related stressors affecting a sample of 28 adult Bosnian refugees in Chicago. The interviews covered 3 areas: life in prewar Bosnia, the journey of exile, and, most centrally, life in Chicago. Primary sources of exile-related distress included social isolation and the loss of community, separation from family members, the loss of important life projects, a lack of environmental mastery, poverty and related stressors such as inadequate housing, and the loss of valued social roles. The implications of these findings for mental health interventions with refugees are considered, and the value of narrative methods in research with refugee communities is discussed.

The Peer Preference Test as a measure of reward value: item analysis, cross-validation, concurrent validation, and replication.

Thirty-six preschoolers were administered and retested on a 15-item Peer Preference Test designed to measure the reward value of peers for each child. Test-retest reliability was .88, and after item analyses, 12 items were maintained in the test. The revised test was then administered to 29 other preschoolers. Test-retest reliability was .77, and item analyses indicated that each item made a significant contribution to the overall test. Concurrent validation of the test was demonstrated using both a picture sociometric and a behavioral measure. In addition, the Evers-Pasquale and Sherman (1975) study was replicated, using 10 preschool social isolates.

Separation and distress--sickness absence and health screening in newly divorced middle-aged Swedish men.

The present study aimed at a description of the sickness absence pattern during 1982-1989 in 32 men who divorced in 1984. Another purpose was to carry through a health screening of the men within six months after the marital disruption focusing on risk factors concerning cardio-vascular disease (smoking, overweight, hypertension) and high alcohol consumption (elevated GGT). The year of divorce and the successive three years (1984-1987) were characterized by high sickness rates (average 21,7 days/year, variation 19,4-26,6) compared to a reference group (average 16,6, variation 14,9-18,1). In the remaining four years (1982-1983 and 1988-1989) the sickness absence was lower in the divorced group (average 12,2, variation 8,7-18,0, reference group: average 17,3, variation 14,8-20,0). The increase was mainly due to short absence periods (self-certifications). The health screening (health examination and record analysis) (n = 29) revealed high frequency of daily smoking and alcohol overconsumption. Overweight and hypertension were not overrepresented. The findings are discussed in relation to a supposed male reaction style to separation. The impact of social isolation is stressed.

Isolation-stress-induced facilitation of passive avoidance memory in the day-old chick.

This study showed that facilitation of recall of a weak version of the 1-trial passive avoidance learning task could be achieved by behavioral "stressing" of day-old chicks after training. Recall, usually retained for less than 9 hr, was extended by socially isolating the chicks for 1 hr immediately after training. There was a brief 3-fold increase in plasma corticosterone levels 10 min after isolation. Facilitated recall was not evident when chicks were isolated 2 hr after training, and it was blocked by intracerebral administration of 2-ng RU 38486, a specific glucocorticoid receptor antagonist, per chick. Male chicks responded more to isolation than did female chicks, presumably a consequence of the additional stress of the injection procedure.

Canine scavenging of human remains in an indoor setting.

This case study documents the nearly complete consumption of adult human remains by two domestic dogs (Canis familiaris) inside a residence. While scavenging behavior has been observed for coyotes, wolves, hyenas and other canines in natural outdoor environments, little information is available concerning canine scavenging of human remains in an indoor setting. In this case, the dogs were confined with the body inside a residence for approximately 1 month. The impact of intrinsic and extrinsic factors on canine scavenging behavior and the postmortem interval are examined, such as clothing on the body, perimortem trauma, drug ingestion and the availability of alternative food sources. While cases of canine scavenging of their owners are scant in the literature, this phenomenon is probably not uncommon, particularly among the elderly and indigent who live alone with pets and are socially isolated.

Facial disfigurement in patients with head and neck cancer: the role of social self-efficacy.

This study investigated the moderating role of social self-efficacy (i.e., the belief that one is capable of exercising control over the reactions and openness of other people) with respect to the link between facial disfigurement and psychological and n = 76) as well as their physicians. In line with the hypotheses, the results revealed that the degree of facial disfigurement, as judged by patients as well as their physicians, was positively related to psychological distress and distress in reaction to unpleasant behavior of others, but only when patients did not feel self-efficacious in social encounters. Furthermore, social self-efficacy mitigated the positive link between facial disfigurement as judged by patients and social isolation.

Early stress and adult emotional reactivity in rhesus monkeys.

This chapter examines the relationship between early social experiences and behavioural and emotional reactivity in adolescence and adulthood that has been established through extensive research with rhesus monkeys. Classic studies carried out in the 1960s first demonstrated that rearing under conditions of social isolation resulted in severe behavioural abnormalities that carried over into adulthood. In the 1970s techniques for reversing such isolation-induced deficits were developed. More recent studies have examined the long-term consequences of more subtle variation in early rearing environments. Monkeys reared from birth without mothers but with extensive peer contact develop relatively normal social behavioural repertoires and function well in familiar and stable social settings. However, peer-reared monkeys display extreme behavioural and physiological reactions to environmental challenges, such as brief social separation, later in life. In contrast, monkeys reared by unusually nurturant foster mothers appear to develop effective strategies for coping with subsequent environmental challenges. Some general principles that have emerged from these studies with rhesus monkeys will be outlined and their implications regarding possible relationships between early social experiences and responses to challenge later in life in humans will be discussed.

Patterns of change in hostility from college to midlife in the UNC Alumni Heart Study predict high-risk status.

OBJECTIVE: To examine hostility measured in college and patterns of change in hostility from college to midlife as predictors of high health-related risk later in midlife. METHODS: Logistic regression models were used to test hostility/risk associations. RESULTS: College hostility predicted being a current smoker, consuming more than two drinks of alcohol, low social support, achieving less than expected in career and in relationships, risk for depression, and appraisal of life changing for the worse in terms of family events at midlife. Change in hostility did not predict smoking and drinking; however, it did significantly predict social isolation, lower income (only for women), obesity, avoidance of exercise, high-fat diet, and negative changes in economic life, work life, and physical health events-all risk indicators measured during the next decade. Appraisals of social support, lowered expectations, risk for depression, and reports of family life changing for the worse were predicted at both time periods. When change in hostility was modeled with college hostility, all risk indicators were significantly predicted by college hostility. CONCLUSIONS: High hostility in college and change in hostility from college to midlife predicts a full range of health risk indicators. When compared with the average population decline in hostility, gains in hostility at midlife are related to increased risk while declines in hostility are related to reduced risk. Higher midlife hostility is associated with increased odds of being in the higher risk group. Future research should focus on developing interventions to reduce hostility.

Medical and social factors associated with psychological distress in a sample of community aged.

Two hundred persons over 80 in two urban communities were interviewed. Of those interviewed, 21% evidenced psychological impairment as defined by the presence of at least one of the following self-report symptoms: 1) depression; 2) periods of inability to function; 3) suicidal ideation; 4) alcohol problems and 5) use of psychotropic medication. A profile of the psychologically impaired group compared to the psychologically healthy showed that accidents (mostly falls), eye problems and few social contacts were significantly associated with impairment. Approximately 75% had some restrictions on activity due to physical health problems. Social isolation was marked: 54% either had no children or saw them less than once a month; 38% visited with close friends or relatives less than once a month; 19% were rated as having very little or no social support; and 23% socialized beyond the household less than once a week. Social interaction was the strongest predictor of psychological wellbeing (Affect Balance Scale) in a multiple regression analysis that included physical health and socioeconomic variables. Questions about service needs and utilization indicated unmet needs in the areas of transportation, house maintenance, medical services, and a regular visiting service.

Abnormal behavior patterns in rhesus monkeys: symptoms of mental disease.

This paper describes the morphology of abnormal behavior of rhesus monkeys which had experienced a certain degree of social isolation. Analysis of the morphology of the behavior starts from the hypothesis that abnormal activities should preferably be interpreted as distortions of normal behavior. The results indicate that all abnormal activities seemed to be symptoms of one social deprivation syndrome, because all activities could tentatively be interpreted as more or less idiosyncratically distorted, often self-directed forms of normally social behavior. The results also illustrate that abnormal behavior patterns can be considered at different levels of integration which should be clearly distinguished in comparative studies. Similarities to the behavior of human mental patients suggest that social deprivation is a prominent factor in a wide variety of mental diseases.

Age differences in sensory and cognitive function in elderly Nepalese.

This paper describes age differences in sensory and cognitive function in a cross-sectional sample of 117 Nepalese men aged 50 to 88 years living in a traditional agrarian society. The prevalence of impairment of vision, hearing, vibration sensitivity, and cognitive function is progressively higher in successively older age categories in this society as it is in Western industrial societies. This has practical consequences for everyday life. Men with vision impairment are less likely to retain the esteemed social role of head of an extended household. Men with visual and hearing impairment leave their household compounds less frequently, have less frequent social contacts outside their households, and remain inactive a greater proportion of the time. In this technologically simple society without modern medical remedies, vision and hearing impairments are associated with social roles and daily activity patterns that foster economic and political dependence and social isolation.
