The relationships among early stress, maternal social network supports, and mother-infant functioning during later infancy were explored in a group of 52 mothers and their high-risk premature infants. Maternal stress and support data were collected 1 month after infants were released from the hospital, and measures of parenting, mother-infant interaction, infant social and developmental competence, and infant attachment were collected at infant corrected ages of 8 and 12 months. Results indicated that stress and support from various ecological sources, including professionals, were related to parent and infant outcomes at both measurement occasions. Varying sources of support differentially predicted varying parent and infant measures where support had a stress buffering effect only under certain conditions. Professional support was found to account for significant amounts of variance in relation to some parenting factors beyond that attributable to other support sources. The results are discussed within the context of previous support findings and in relation to transactional models of high-risk infant development.  相似文献

The goals of this paper are (1) to introduce a methodology developed to study mother-infant separations that occur in the context of normal family life, including but going beyond separations associated with maternal employment; (2) to present illustrative data that describe the range of separations experienced by one sample of infants; and (3) to demonstrate how a focus on specific underlying dimensions results in a more precise characterization of the separation experience. It is necessary to identify the specific dimensions on which mother-infant separations vary in order to clarify which aspects of separation are relevant to child outcome. Detailed histories of mother-infant separations and concomitant substitute care during the first year of life were obtained by interview from 144 middle-class mothers of first-born infants. Far from being an unusual event, separation from mother was a normal experience during infancy for this sample. Six types of separation were identified, the majority of which have not been studied previously. Analyses indicated that naturally occurring mother-infant separations can be differentiated statistically and compared in terms of amount of separation, stability of care, characteristics of caregivers, and characteristics of the substitute care setting.  相似文献

The Counselling Interview Rating Form (CIRF) was developed to evaluate trainee counsellors' use of microskills and other aspects of the counselling session. The CIRF provides a structured format for evaluation that enhances the teaching and learning of interviewing skills by supervisors and trainee counsellors respectively. Uses of the CIRF in educational and clinical settings are described.  相似文献

OBJECTIVE: We ask whether subjective socioeconomic status (SES) predicts who develops a common cold when exposed to a cold virus. DESIGN: 193 healthy men and women ages 21-55 years were assessed for subjective (perceived rank) and objective SES, cognitive, affective and social dispositions, and health practices. Subsequently, they were exposed by nasal drops to a rhinovirus or influenza virus and monitored in quarantine for objective signs of illness and self-reported symptoms. MAIN OUTCOME MEASURES: Infection, signs and symptoms of the common cold, and clinical illness (infection and significant objective signs of illness). RESULTS: Increased subjective SES was associated with decreased risk for developing a cold for both viruses. This association was independent of objective SES and of cognitive, affective and social disposition that might provide alternative spurious (third factor) explanations for the association. Poorer sleep among those with lesser subjective SES may partly mediate the association between subjective SES and colds. CONCLUSIONS: Increased Subjective SES is associated with less susceptibility to upper respiratory infection, and this association is independent of objective SES, suggesting the importance of perceived relative rank to health.  相似文献

By comparing the overexcitability scores of 27 Venezuelan and 23 American artists, support was found for the hypothesis that creative individuals show a high degree of animistic, intuitive, and emotional thinking. Overexcitability refers to heightened mental functioning in Dabrowski's (1964) theory of emotional development. Along with other special talents and abilities, it represents the developmental potential for intensified personality growth. Scores on 4 of the 5 dimensions of overexcitability were not significantly different for American and Venezuelan artists. This evidence of similar profiles for artists in 2 different societies demonstrates cross-cultural validity for the concept of developmental potential.  相似文献
