The Family System Functioning (FSF) scale is a new instrument for measuring dimensions of the intrafamilial environment thought to be important in recovery from major psychiatric illness. Modest statistical correlations were obtained when FSF ratings of laboratory-based family interactions were compared with researcher-guided therapist ratings of FSF based upon the family's behavior in family therapy sessions during the subsequent month. The data from these two settings provide support for the validity of some of the scales. Because of the modest size of the correlations, however, behavior in the laboratory setting may not always be an accurate indicator of how the family will behave in the early weeks of family therapy. 相似文献

This article is the first of three that will present data from the Timberlawn Psychiatric Research Foundation Young Family Project, a study of the development over time of competent family systems. The Project is briefly described and findings are presented from the initial data collection period. The operational definitions of marital competence and the Continuum of Marital Competence are presented, and the data are interpreted to suggest that the spouses' levels of individual psychological health, their agreement on values, and their socioeconomic status are related to the level of marital competence. The level of prenatal marital competence at Time 1 is used as an independent variable with which to predict both changes in marital structure and incorporation of the child into the family system at 3 months and 1 year postpartum. The results of these analyses will be presented in two subsequent articles. 相似文献

In recent years in research on intergroup relationships, the assumption has increasingly been made that discrimination dominates decisions when individuals allocate resources between (members of) own and other group. Conversely, in empirical studies of interpersonal decision-making, including an extensive literature on the development of children's allocation rules within dyadic relationships, it has been repeatedly observed that in dyadic relationships choices though responsive to various changes in the environment, are more strongly governed by fairness rules. The present research extends the interpersonal fairness paradigm to the intergroup case, and examines the effects of some of those variables, namely, children's age, input and attitudes toward other, that have been observed to influence choice behaviour within interpersonal relationships. The findings indicate that as children are socialized, fairness rules also play an increasing dominant role in intergroup allocation decisions, and that both relative input and the language of the outgroup influence such decisions. At the same time, there is some preliminary evidence to indicate that the relative strength of self-interest may be somewhat stronger in intergroup than in interpersonal relationships. Finally, a number of the issues that must be confronted in comparing the two more important forms of human social choices, interpersonal and intergroup decision-making, are considered. 相似文献

ABSTRACT In his book Sexual Desire , Roger Scruton wrongly maintains that human sexual experience is essentially intentional. His thesis depends on his highly revisionary definitions of 'sexual arousal' and 'sexual desire', the artificial nature of which I expose and criticise.
He admits that homosexual desire is capable of the same kind of intentionality as heterosexual desire, and is therefore not intrinsically obscene or perverted, but he advances reasons why homosexuality is morally different from heterosexuality and is therefore an object of disapproval. His arguments presuppose 'an impassable moral divide' between the sexes and are, on his own admission, not very cogent.
Since he allows that homosexual desire is a natural and spontaneous phenomenon and also proposes that moral education should guide us towards a state in which our sexuality is entirely integrated within a life of personal affection and responsibility, consistency requires that he adopt a sexual ideology which does not discriminate against homosexuality. For homosexuals are unlikely to achieve the 'sexual integrity' which Scruton advocates (and which I endorse) if they are constantly encouraged to disparage their own sexual nature and if social institutions make no positive provision for them. 相似文献

The relationship between anxiety and depression was examined in a sample of 106 children and adolescents referred to an outpatient anxiety disorder clinic for children. Twenty-eight percent of patients with DSM-III diagnoses of anxiety disorders displayed a concurrent major depression. Children with anxiety disorders plus major depression were found (1) to be older, (2) to demonstrate more severe anxiety symptomatology, and (3) to be diagnosed with different rates of certain anxiety-disorder subtypes, when compared to anxious patients without major depression. Nondepressed anxious children and adolescents did not differ from a psychopathological control group in severity of either anxiety or depression symptoms. 相似文献

Differences between a clinical sample of younger (ages 5 to 11) and older (ages 12 to 19) children meeting DSM-III criteria for overanxious disorder (OAD) were examined. Younger and older children were compared in terms of (1) the rates of OAD diagnoses occurring in the two age groups, (2) sociodemographic characteristics, (3) symptom expression, (4) association with other forms of maladjustment, and (5) self-reported anxiety and depression. The prevalence of OAD diagnoses and sociodemographic characteristics did not differ. Although younger and older OAD children showed similar rates of most specific DSM-III OAD symptoms, older children presented with a higher total number of overanxious symptoms than younger children. Older children more frequently exhibited a concurrent major depression or simple phobia, whereas younger OAD children more commonly had coexisting separation anxiety or attention deficit disorders. Older OAD children reported significantly higher levels of anxiety and depression on self-report measures. Findings indicated that the expression of OAD varies by developmental level. 相似文献
