This study examined the contribution of individual and family variables to depressive symptoms among youths in a family-centered culture. Participants were 262 Mexican adolescents (mean age = 15.9 years). At the individual level, gender (being female) and higher levels of perceived stressfulness of life events and ruminative coping style were correlated with higher frequency of depressive symptoms. At the family level, higher levels of perceived parental warmth and acceptance and parental monitoring were correlated with lower levels of depressed mood, whereas higher levels of parent-adolescent conflict were associated with greater frequency of depressive symptoms. Regression analyses confirmed our prediction that both individual factors (gender, ruminative coping) and family factors (parental warmth and parental monitoring) would make unique contributions to depressive symptoms. The model comprised of individual and family variables accounted for 50% of the variance in depressed mood. Moreover, parental warmth and acceptance attenuated the impact of ruminative coping style on adolescents' depressive symptomatology. Findings are discussed in relation to previous research on adolescents in another family-centered culture (China), and directions for future research are proposed.  相似文献

A critical question about early word learning is whether word learning constraints such as mutual exclusivity exist and foster early language acquisition. It is well established that children will map a novel label to a novel rather than a familiar object. Evidence for the role of mutual exclusivity in such indirect word learning has been questioned because: (1) it comes mostly from 2 and 3-year-olds and (2) the findings might be accounted for, not by children avoiding second labels, but by the novel object which creates a lexical gap children are motivated to fill. Three studies addressed these concerns by having only a familiar object visible. Fifteen to seventeen and 18-20-month-olds were selected to straddle the vocabulary spurt. In Study 1, babies saw a familiar object and an opaque bucket as a location to search. Study 2 handed babies the familiar object to play with. Study 3 eliminated an obvious location to search. On the whole, babies at both ages resisted second labels for objects and, with some qualifications, tended to search for a better referent for the novel label. Thus mutual exclusivity is in place before the onset of the naming explosion. The findings demonstrate that lexical constraints enable babies to learn words even under non-optimal conditions--when speakers are not clear and referents are not visible. The results are discussed in relation to an alternative social-pragmatic account.  相似文献

The authors examined mothers' and fathers' avoidance and attacking conflict-resolution strategies in the marriage and their depressive symptoms as they related to children's externalizing and internalizing behaviors. A nonclinical community sample of 51 families and their children's 1st-grade teachers (N = 41) participated. Both mothers and teachers completed a behavior-problem checklist in order to evaluate the incidence of internalizing and externalizing behaviors in the children. Correlational statistics revealed significant associations between parents' avoidance and attacking strategies and their depressive symptoms. Also, parents' use of avoidance was related to more internalizing behaviors in the children. When hierarchical regression analyses were used to examine the contributions of the parents' attributes to children's externalizing and internalizing behaviors, mothers' avoidance and an interaction between mothers' and fathers' avoidance were identified as significant predictors of children's internalizing behaviors.  相似文献

We examined clinically depressed (CD; n = 16), previously depressed (PD; n = 19) and never depressed (ND; n = 18) individuals on 13 theoretically selected Rorschach (Exner, 1993; Rorschach, 1942) variables and on the Beck Depression Inventory (BDI; Beck, Rush, Shaw, & Emery, 1979). The group assignment was made according to the criteria of Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). We tested 2 contradictory models for depressive vulnerability, Beck's (Clark & Beck, 1999) and Miranda and Persons's (1988; Persons & Miranda, 1992), in a planned comparison design with focused contrasts. The CDs significantly contrasted the combined group of NDs and the PDs in a pathological direction on 8 of the 13 Rorschach variables and on the BDI. However, the combined group of CDs and PDs also significantly contrasted the NDs in a pathological direction on 3 of these Rorschach variables and on the BDI. In addition, logistic regression analyses indicated that Rorschach indexes significantly improved the prediction of major depression above and beyond that achieved by the BDI. The findings show that the Rorschach method was able to identify (a) cognitive and aggressive disturbances that are present in individuals who are actively depressed but not in individuals who have been depressed in the past or never been depressed and (b) affective and coping disturbances that are present in depressed individuals and to some degree in PD individuals but not in individuals who have not experienced depression. We discuss the scanty evidence of psychological disturbances in PD individuals, as measured with the Rorschach, in relation to the mood-state dependent hypothesis of Miranda and Persons (1988; Persons & Miranda, 1992).  相似文献

The Adaptive Counseling and Therapy (ACT: Howard, Nance, & Myers, 1986) model was used to predict who would benefit from computerized career counseling. Specifically, clients who had more stable goals and aspirations and more defensive independence were expected to derive more benefit from computerized career counseling, an intervention that provides low levels of direction and support. A total of 54 clients who came to the Career Planning and Placement Center seeking career assistance were referred to the System for Interactive Guidance and Information PLUS (SIGI-PLUS). As hypothesized, clients with more stable goals had the greatest gains in vocational identity. Additionally, clients who showed more defensive independence were more satisfied with the SIGI-PLUS treatment. Implications, limitations, and suggestions for future research are discussed.  相似文献

This study demonstrated that the content of prenatal genetic counseling sessions varied from counselor to counselor and from center to center. The study was designed to examine which specific issues were included by genetic counselors in prenatal genetic counseling sessions, and to determine which factors led genetic counselors to include or exclude this information from such sessions. Data were collected by randomly surveying 200 full, master degree members of the National Society of Genetic Counselors (NSGC). Respondents provided information by deciding which of 45 specific issues they would include in a standard prenatal genetic counseling session, and which one factor from a bank of 11 factors most accurately described the reason for this decision. The results indicated that the issues included/excluded from sessions varied widely among genetic counselors. The results also indicated that Patient Education/Informed Decision Making (34.5%) played the largest role in decision making overall, with Standard at Center/Departmental Policy (17.6%), Personal Experience/Preference (12.4%), and Applicability (10.9%) serving as the next three most important reasons for including or excluding issues from prenatal genetic counseling sessions.  相似文献

Genetic counseling for Gaucher disease is complicated by the vast degree of clinical heterogeneity encountered in the disorder. Recent advances in our understanding of the molecular genetics of Gaucher disease are particularly relevant to genetic counseling. Although the identification of mutations in the glucocerebrosidase gene has enabled genotypic screening of Gaucher patients, the ability to reliably predict patient outcome on the basis of DNA studies is often limited. An appreciation of both the spectrum of clinical manifestations in Gaucher patients and the limitations of the available genotypic information is necessary when counseling patients, families and at-risk individuals.  相似文献
