Socioeconomic disadvantage is associated with increased exposure to victimization and traumatic stress. The present study evaluates longitudinal pathways linking victimization and trauma to depressive symptoms in a socioeconomically disadvantaged sample of African-American adolescent girls seeking mental health services (N = 177, 12–16 years old at baseline). Girls completed four assessments over the course of three years (T1-T4). Depressive symptoms were assessed at T1-T3 using clinical interviews and questionnaires. At T4, lifetime history of victimization and traumatic stressors was evaluated with in-person interviews. Separate structural equation models tested longitudinal pathways from stressor frequency, severity, and duration to depressive symptoms. In all three models, higher levels of victimization and traumatic stressors were associated with significantly higher levels of depressive symptoms. More frequent stressors prior to T1 directly predicted depressive symptoms at T1 and indirectly predicted depressive symptoms at T2, which, in turn, predicted depressive symptoms at T3. A similar pattern emerged in the stressor severity and duration models. Findings support the idea that victimization and traumatic stressors are associated with higher levels of depressive symptoms and that, among treatment-seeking low-income adolescent girls, these effects occur through both direct and indirect paths. Implications of these findings are discussed in the context of the stress-generation and stress proliferation models of psychopathology.  相似文献

Stress exposure and reactivity models were examined as explanations for why girls exhibit greater levels of depressive symptoms than boys. In a multiwave, longitudinal design, adolescents' depressive symptoms, alcohol usage, and occurrence of stressors were assessed at baseline, 6, and 12 months later (N=538; 54.5% female; ages 13-18, average 14.9). Daily stressors were coded into developmentally salient domains using a modified contextual-threat approach. Girls reported more depressive symptoms and stressors in certain contexts (e.g., interpersonal) than boys. Sex differences in depression were partially explained by girls reporting more stressors, especially peer events. The longitudinal direction of effects between depression and stressors varied depending on the stressor domain. Girls reacted more strongly to stressors in the form of depression.  相似文献

This simulation study demonstrates how the choice of estimation method affects indexes of fit and parameter bias for different sample sizes when nested models vary in terms of specification error and the data demonstrate different levels of kurtosis. Using a fully crossed design, data were generated for 11 conditions of peakedness, 3 conditions of misspecification, and 5 different sample sizes. Three estimation methods (maximum likelihood [ML], generalized least squares [GLS], and weighted least squares [WLS]) were compared in terms of overall fit and the discrepancy between estimated parameter values and the true parameter values used to generate the data. Consistent with earlier findings, the results show that ML compared to GLS under conditions of misspecification provides more realistic indexes of overall fit and less biased parameter values for paths that overlap with the true model. However, despite recommendations found in the literature that WLS should be used when data are not normally distributed, we find that WLS under no conditions was preferable to the 2 other estimation procedures in terms of parameter bias and fit. In fact, only for large sample sizes (N = 1,000 and 2,000) and mildly misspecified models did WLS provide estimates and fit indexes close to the ones obtained for ML and GLS. For wrongly specified models WLS tended to give unreliable estimates and over-optimistic values of fit.  相似文献

This study compares five cognitive diagnostic models in search of optimal one(s) for English as a Second Language grammar test data. Using a unified modeling framework that can represent specific models with proper constraints, the article first fit the full model (the log-linear cognitive diagnostic model, LCDM) and investigated which model emerged as the dominant model. It then fit the dominant model and the other models to confirm that the model provides the best fit to the data. The model found to represent the most number of items in the test was the Compensatory Reparameterized Unified Model (C-RUM) and other models compared were the Deterministic-Input, Noisy-And (DINA), Deterministic Input, Noisy-Or-gate (DINO), and Noisy Input, Deterministic-Or-gate (NIDO). The absolute (item-association root mean square error values) and relative (information criteria) model fit indices also indicated that the LCDM and the C-RUM were the best fit to the data. More detailed analyses on the functioning of the C-RUM were conducted and the interpretation of the results was included in the discussion section. The article ends with some suggestions for future research based on the limitations of the study.  相似文献

Using interview data from a sample of 241 single African American mothers and their seventh- and eighth-grade children, this study tests a model of how 2 economic stressors, maternal unemployment and work interruption, influence adolescent socioemotional functioning. In general, these economic stressors affected adolescent socioemotional functioning indirectly, rather than directly, through their impact on mothers' psychological functioning and, in turn, parenting behavior and mother-child relations. Current unemployment, but not past work interruption, had a direct effect on depressive symptomatology in mothers. As expected, depressive symptomatology in mothers predicted more frequent maternal punishment of adolescents, and this relation was fully mediated by mothers' negative perceptions of the maternal role. More frequent maternal punishment was associated with increased cognitive distress and depressive symptoms in adolescents, and consistent with predictions, these relations were partially mediated by adolescents' perceptions of the quality of relations with their mothers. Increased availability of instrumental support, as perceived by mothers, predicted fewer depressive symptoms in mothers, less punishment of adolescents, and less negativity about the maternal role. Both economic stressors were associated with higher levels of perceived financial strain in mothers, which in turn predicted adolescents' perceptions of economic hardship. Adolescents who perceived their families as experiencing more severe economic hardship reported higher anxiety, more cognitive distress, and lower self-esteem.  相似文献

In an attempt to understand the cognitive mechanisms by which parental attachments predict depression among African American college students, the authors examined a mediational path model containing parental attachment, cognitive working models, and depression. The model demonstrated a close fit to the data, and several significant paths emerged. The authors provide recommendations for counselors practicing in college counseling centers and suggest directions for future research.  相似文献

Objective. This research study tested a social cognitive model in which family socioeconomic status (SES) and neighborhood quality predicted parental efficacy, which then predicted the academic and social-emotional adjustment of adolescents through 3 parental behaviors (monitoring, parental involvement, and parent-adolescent communication). Design. The study investigated parental efficacy among a stratified random sample of 929 parents and their adolescent children in the United States. Parents and adolescents provided reports through telephone interviews. Structural equation modeling tested the model fit for the overall sample and for European American (n = 387), African American (n = 259), and Latin American (n = 283) subsamples. Results. The model fit for the overall sample and for each racial or ethnic group. Paths within each model also were examined. For the overall sample, neighborhood quality predicted parental efficacy, parental efficacy predicted reported parental involvement and monitoring, both of which predicted academic and social-emotional adjustment of adolescents, and parent-adolescent communication predicted social-emotional adjustment. Some racial or ethnic differences in paths emerged. Conclusions. Overall, the study supported predictions made by social cognitive theory. Given the link between parental efficacy, parenting behaviors, and adolescent outcomes, 1 important goal of programs for parents of adolescents might be to bolster parental efficacy.  相似文献

Maltreated children usually show a specific pattern of emotional and behavioral symptoms that exceed those relating to posttraumatic stress disorder (PTSD). These symptoms have been defined as Complex PTSD (CPTSD). The underlying attentional mechanisms of abnormal emotional processing and their relation to the clinical presentation of CPTSD are not well understood. A visual dot-probe paradigm involving pre-attentive (i.e., 500 ms) and attentive (i.e., 1500 ms) presentation rates of neutral versus emotional (i.e., angry, happy or sad) facial expressions was applied. Twenty-one maltreated CPTSD children were compared with twenty-six controls. The results are as follows: an attention bias away from threatening faces and an attentional bias towards sad faces were observed in maltreated CPTSD children during pre-attentive and attentive processing. Whereas the attentional bias away from angry faces was associated with social problems, the attentional bias towards sad faces was associated with depressive and withdrawn symptoms. Therefore, CPTSD children develop maladaptive negative cognitive styles, which may underlie not only social problems (by a cognitive avoidance of threatening stimuli) but also depressive symptoms (by a cognitive approach to sad stimuli). Attention processing abnormalities should be considered as therapeutic targets for new treatment approaches in this population.  相似文献

A theoretical model of early environment action was examined on a sample of 282 infants representing two racial groups (Caucasian, African-American). Children were obtained from three different sites in the United States. The model examined included the following variables: socioeconomic status (SES), early cognitive status (Bayley MDI at 12 months), stimulation within the home environment (subscales from the HOME Inventory at 12 and 24 months), parents use of negative control (subscales from the HOME Inventory at 12 and 24 months), and later cognitive status (36-month Stanford-Binet IQ). Structural Equation Modeling (SEM) with the LISREL software was used to confirm the fit of the model for African-Americans and Caucasians and for males and females separately. The models for males and females had similar structures, but not equal coefficients for all paths in the model. The models showed significant paths from socioeconomic status and early cognitive status to stimulation with the home environment, a significant path from SES to negative parental control, and a significant path from stimulation within the home environment to later cognitive status. The models for African-Americans and Caucasians differed in structure. For African-Americans, there was no evidence that the link between SES and 36-month IQ was mediated through negative control but SES and early cognitive status were linked to later IQ via the amount of stimulation provided in the home. For Caucasians, early cognitive status did not appear related to 36- month IQ but negative control did appear to mediate the relation between SES and IQ.  相似文献

ObjectiveThe Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a self-report questionnaire that retrospectively provides screening for a history of childhood abuse and neglect, and which is widely used throughout the world. The current study aimed to examine the psychometric properties of the Chinese version of the CTQ-SF.MethodsParticipants included 3431 undergraduates from Hunan provinces and 234 depressive patients from psychological clinics. Confirmatory factor analysis was performed to examine how well the original five-factor model fit the data and the measurement equivalence of CTQ-SF across gender. Internal consistency was also evaluated.ResultsThe five-factor model achieved satisfactory fit (Undergraduate sample TLI = 0.925, CFI = 0.936, RMSEA = 0.034, SRMR = 0.046; depressive sample TLI = 0.912, CFI = 0.923, RMSEA = 0.044, SRMR = 0.062). Measurement invariance of the five-factor model across gender was supported fully assuming different degrees of invariance. The CTQ-SF also showed acceptable internal consistency and good stability.ConclusionThe current study provides that the Chinese version of the Childhood Trauma questionnaire-short form has good reliability and validity among Chinese undergraduates and depressive samples, which also indicates that the CTQ-SF is a good tool for child trauma assessment.  相似文献

A longitudinal investigation was conducted to explicate the network of associations between depressive symptoms and peer difficulties among 486 fourth through sixth graders (M = 9.93 years). Parent and teacher reports of depressive symptoms; peer, self, and teacher reports of victimization; and peer reports of peer acceptance were obtained. A systematic examination of nested structural equation models provided support for a symptoms-driven model whereby depressive symptoms contributed to peer difficulties; no evidence was found for interpersonal risk or transactional models. Analyses further revealed that victimization mediated the association between prior depressive symptoms and subsequent peer acceptance. Results extend knowledge about the temporal ordering of depressive symptoms and peer difficulties and elucidate one process through which depressive symptoms disrupt peer relationships.  相似文献

Many studies have reported an increase in mental health problems during post-secondary transition, often originating from high school years. The present study examined how depressive symptoms during the 2 years following the post-secondary transition could be predicted by, on the one hand, school performance, externalized and learning difficulties, and depressive symptoms before the post-secondary transition, and on the other hand, personal factors, family functioning, and adjustment to college after the transition. From a sample of 438 participants (M = 16.20, SD = 0.87) at time point 1, an integrated model was elaborated using structural equation modeling. The statistical analyses showed that the five constructs fit the data well. The path coefficients showed a negative relationship between externalized and learning problems as perceived by the teacher (ELPT) before the transition and academic performance (AP). Personal characteristics (PC) negatively predicted academic adjustment (AC) over time, whereas the path coefficients between the family factor (FF) and AC were not significant over time. ELPT and AP negatively predicted depression at time point 1. At time points 2 and 3, PC positively predicted depression, and depressive symptoms were positively related over time. The percentage of variance accounted for by the depressive symptoms increased over time.  相似文献

This study examined associations of intragroup marginalization and cultural incongruity with acculturative stress and depressive symptoms among 155 undergraduate U.S. college students of Mexican heritage. Findings indicate that perceived interpersonal distancing by the family (intragroup marginalization) and perceived lack of cultural fit between the respondent and academic institution (cultural incongruity) had statistically significant direct and indirect effects on depressive symptoms via acculturative stress. Results also show that 39.7 % of the variance corresponding with depressive symptoms was accounted for by intragroup marginalization, cultural incongruity, acculturative stress, and other exogenous variables.  相似文献

The purpose of this study is to examine the relationship between perceived ageism and depression in later life and to clarify the mechanism underlying this relationship by examining the mediating effects of self-perception of aging and purpose in life. The Health and Retirement Study surveys were used for this secondary analysis of data. The sample included 3,991 older adults, and structural equation modeling (SEM) analyses using structural regression models were conducted. SEM analyses revealed that full mediation effects of self-perception of aging and purpose in life exist. Older adults who perceive ageism are likely to have negative self-perception of aging, and this negative view of their own aging is likely to decrease purpose in life and increase depressive symptoms. The results of this study imply that more efforts and resources are necessary to reduce ageism and its negative effect on depression among older adults. Additionally, the current study suggests the necessity of anti-ageism policies and social services. Increasing positive self-perception of aging, purpose in life, and resilience could be the key to a better quality of life for older adults.  相似文献

The main aim of this study was to investigate the relationships between life satisfaction, gender, social security, and depressive symptoms of the Turkish elderly. This cross-sectional study included 216 (female = 127, male = 89) participants with ages ranging from 60 to 93 years (mean = 71.60 ± 7.39). Information Gathering Form and Life Satisfaction and Geriatric Depression Scales were used for data collection. It was determined that 42.1% of the elderly who participated in this study had high depressive symptoms scores. Life satisfaction (OR = 0.63, 95% CI = 0.53–0.71), lack of social security benefits (OR = 3.52, 95% CI = 1.25–9.89), and gender (OR = 2.53, 95% CI = 1.17–5.50) predicted the depressive symptoms significantly. The results of the study indicate that while depression risk increases, life satisfaction decreases. In addition, lack of social security benefits and being female also increase the risk of depression in the Turkish elderly.  相似文献

OBJECTIVE: The aim was to examine how traumatic and stressful events, responses to violence, child characteristics, and mothering quality, as measured in middle childhood predict psychological distress and positive resources in adolescence. METHOD: The participants were 65 Palestinian adolescents (17+/-.85 years; 52% girls), who had been studied during the First Intifada (T1), during the Palestinian Authority rule (T2) and before the Second Al Aqsa Intifada (T3) in Gaza. Psychological distress was indicated by PTSD, and depressive symptoms and positive resources by resilient attitudes and satisfaction with quality of life, all measured at T3. The predictors that were measured at T1 were exposure to military violence, active coping with violence and children's intelligence, cognitive capacity, and neuroticism. Mothering quality and stressful life-events were measured at T2, the former reported by both the mother and the child, and the latter by the mother. RESULTS: Adolescents' PTSD symptoms were most likely if they had been exposed to high levels of traumatic and stressful experiences and had poor cognitive capacity and high neuroticism in middle childhood. Only high levels of childhood military violence and stressful life-events predicted high depressive symptoms and low satisfaction with quality of life in adolescence. CONCLUSIONS: Military violence in childhood forms risks for both increased psychological distress and decreased positive resources. However, child characteristics such as cognitive capacity and personality are important determinants of psychological vulnerability in military trauma.  相似文献

We evaluate the performance of the most common estimators of latent Markov (LM) models with covariates in the presence of direct effects of the covariates on the indicators of the LM model. In LM modeling it is common practice not to model such direct effects, ignoring the consequences that might have on the overall model fit and the parameters of interest. However, in the general literature about latent variable modeling it is well known that unmodeled direct effects can severely bias the parameter estimates of the model at hand. We evaluate how the presence of direct effects in?uences the bias and efficiency of the 3 most common estimators of LM models, the 1-step, 2-step, and 3-step approaches. Furthermore, we propose amendments (that were thus far not used in the context of LM modeling) to the 2- and 3-step approaches that make it possible to account for direct effects and eliminate bias as a consequence. This is done by modeling the (possible) direct effects in the first step of the stepwise estimation procedures. We evaluate the proposed estimators through an extensive simulation study, and illustrate them via a real data application. Our results show, first, that the augmented 2-step and 3-step approaches are unbiased and efficient estimators of LM models with direct effects. Second, ignoring the direct effects leads to biased estimates with all existing estimators, the 1-step approach being the most sensitive.  相似文献

OBJECTIVE: The aim of this study was to examine associations between childhood adversity, parental bonding, gender, depressive symptoms, and quality of life in non-treatment-seeking adults from the community. METHOD: Effects of differential parental rearing were compared in adults who reported a high degree of childhood maltreatment (n=72) and those who reported no significant adverse events in childhood (n=69). Subjects completed retrospective measures of childhood maltreatment and perceived parenting style, as well as measures of current depressive symptoms and quality of life. RESULTS: The subjects without childhood maltreatment were younger and endorsed less current depressive symptomatology than did subjects with childhood maltreatment. While the subjects without a history of maltreatment reported more "optimal" bonding experiences with their parents, the maltreatment group members were more likely to characterize their early parental bonding experiences in terms of "affectionless control" (p<.001 for both maternal and paternal parenting), "affectionate constraint" (p=.025 for maternal parenting and p=.004 for paternal parenting), or "weak or absent" bonding (p<.001 for both maternal and paternal parenting). Results of a multiple regression analysis revealed that overall quality of paternal care (p=.015) and current level of depressive symptoms (p<.001) were significant independent predictors of adult quality of life. Gender effects between subjects providing parental bonding data were limited to the group with childhood maltreatment. CONCLUSION: These findings extend previous work documenting a relationship between early life maltreatment and suboptimal parental bonding, suggesting gender-specific effects of maternal and paternal care. Effects of childhood maltreatment on quality of life in adulthood appear to be linked with the quality of childhood paternal care and the occurrence of depressive symptomatology in adulthood, suggesting possible targets for primary or secondary prevention.  相似文献
