A prenatal intervention designed to prevent the onset of major depressive episodes (MDEs) during pregnancy and postpartum was pilot tested at a public sector women’s clinic. The Mamás y Bebés/Mothers and Babies Course is an intervention developed in Spanish and English that uses a cognitive-behavioral mood management framework, and incorporates social learning concepts, attachment theory, and socio-cultural issues. The four goals of this project were to develop the intervention, assess its acceptability, test the feasibility of conducting a randomized trial with public sector patients, and obtain estimates of its effect size. Forty-one pregnant women at high risk for developing MDEs were randomized to the Mothers and Babies Course (n = 21) or a comparison condition (n = 20). Assessments occurred during pregnancy and at 1, 3, 6, and 12 months postpartum. Differences in terms of depression symptom levels or incidence of MDEs between the two groups did not reach statistical significance in this pilot trial. However, the MDE incidence rates of 14% for the intervention condition versus 25% for the comparison condition represent a small effect size (h = 0.28) that will be further examined in a larger scale study. The intervention was well received by the participants and implementation of a randomized trial appeared quite feasible as indicated by our follow-up rate of 91% at 12 months. Implications for the continuing development of preventive interventions for perinatal depression are discussed.  相似文献

We examine the notion of conditionals and the role of conditionals in inductive logics and arguments. We identify three mistakes commonly made in the study of, or motivation for, non-classical logics. A nonmonotonic consequence relation based on evidential probability is formulated. With respect to this acceptance relation some rules of inference of System P are unsound, and we propose refinements that hold in our framework.  相似文献

Understanding the implementation of evidence-based practice (EBP) in community service settings is critical for the successful translation of research to practice. However, we have limited research evidence about the impact of EBP implementation on the mental health and social service workforce. In a previous study we demonstrated reduced staff turnover where an EBP was implemented with fidelity monitoring in the form of supportive ongoing supervision and consultation. Other research has shown that staff burnout and emotional exhaustion in particular is associated with poor quality of care and increased staff turnover intentions and turnover. Current research, however, has focused less on the effects that EBP implementation may have on staff emotional exhaustion. The present study investigates the association of EBP implementation and fidelity monitoring with staff emotional exhaustion in a statewide EBP implementation study. The 21 case-management teams in this study were randomized in a 2 (EBP vs. services as usual [SAU]) by 2 (monitoring vs. no monitoring) design. The EBP in this study was SafeCare®, a home-based intervention that aims to reduce child neglect in at-risk families. SafeCare was developed from a behavior analysis approach and is based in cognitive behavioral principles. In keeping with our previous research, we hypothesized that providers implementing SafeCare with monitoring would have the lowest levels of emotional exhaustion and those receiving additional monitoring not in the context of EBP implementation would have higher emotional exhaustion relative to the other groups. Results supported our hypotheses in that we found lower emotional exhaustion for staff implementing the EBP but higher emotional exhaustion for staff receiving only fidelity monitoring and providing SAU. Together, these results suggest a potential staff and organizational benefit to EBP implementation and we discuss implications of the findings relative to EBPs and to fidelity monitoring.  相似文献

Characters break the fourth wall on television when they speak directly to the camera. Using a stratified random sample of one episode of every situation comedy, drama, and reality program airing on the five broadcast networks in the United States (N?=?113) during the 2006–2007 prime-time season, we found that, overall, male characters broke the fourth wall more frequently than females. However, when a program employed at least one woman in a powerful behind-the-scenes position, female characters broke the fourth wall more than males. Also, male characters breaking the fourth wall were more likely to make personal comments about themselves and others, whereas female characters talked about competitive strategy and competition.  相似文献

Forgiveness interventions can help people forgive past offenses. However, few studies have compared forgiveness interventions with genuine alternative treatments. The authors compared forgiveness interventions with a therapeutic alternative treatment. Participants reduced unforgiveness and increased forgiveness regardless of treatment condition. Trait forgivingness was not related to change in forgiveness, whereas greater offender contrition was related to greater reductions in unforgiveness. The type of treatment may not be as important as factors common to the interventions.  相似文献

We examined parental experience of having a child with obsessive-compulsive disorder (OCD) in 62 parent–child dyads. Youth with a primary diagnosis of OCD and their parent(s) were administered the CY-BOCS jointly by a trained clinician. Parents completed several measures about their child’s OCD-related impairment and accommodation, emotional and behavioral functioning, parental distress, caregiver stress, and parental experiences of having a child with OCD. Results indicated that parents of children with OCD are considerably distressed about their child’s condition. As expected, negative parental experiences (e.g., anxiety about child’s condition, uncertainty about their future) were directly related to OCD symptom severity and impairment, as well as child internalizing and externalizing problems, family accommodation of symptoms, and caregiver strain. The presence of emotional resources was negatively related to most outcomes, although some of these relationships did not achieve statistical significance. The presence of internalizing symptoms mediated the relationship between parental experiences and parental distress. Given these findings, addressing parental experiences as part of a family based cognitive-behavioral treatment program for pediatric OCD may help reduce parental distress and improve patient prognosis.  相似文献

We examined the relationship of gender and different forms of abuse experience on internalizing symptoms, externalizing symptoms, and IQ in a sample of 397 youngsters who were admitted to a residential treatment program. Three types of abuse experience were examined in this study: sexual abuse only, physical abuse only, and both sexual and physical abuse. Results indicate that girls exhibited higher levels of internalizing and externalizing symptoms even though abuse experience was accounted for in the analyses. Moreover, youngsters who had experienced sexual abuse (but not physical abuse) exhibited higher levels of internalizing and externalizing symptoms than youngsters who had not been abused. Implications for developing individualized interventions based on gender and abuse experience in residential treatment programs is discussed.  相似文献

Despite the unique and challenging circumstances confronting Latino immigrant families, debate still exists as to the need to culturally adapt evidence-based interventions for dissemination with this population. Following the grounded theory approach, the current qualitative investigation utilized focus group interviews with 83 Latino immigrant parents to explore the relevance of culturally adapting an evidence-based parenting intervention to be disseminated within this population. Findings from this study indicate that Latino immigrant parents want to participate in a culturally adapted parenting intervention as long as it is culturally relevant, respectful, and responsive to their life experiences. Research results also suggest that the parenting skills participants seek to enhance are among those commonly targeted by evidence-based parenting interventions. This study contributes to the cultural adaptation/fidelity balance debate by highlighting the necessity of exploring ways to develop culturally adapted interventions characterized by high cultural relevance, as well as high fidelity to the core components that have established efficacy for evidence-based parenting interventions.  相似文献

The inherent confound between the organization of articulation and the acoustic-phonetic structure of the speech signal makes it exceptionally difficult to evaluate the competing claims of motor and acoustic-phonetic accounts of how listeners recognize coarticulated speech. Here we use Granger causation analyzes of high spatiotemporal resolution neural activation data derived from the integration of magnetic resonance imaging, magnetoencephalography and electroencephalography, to examine the role of lexical and articulatory mediation in listeners’ ability to use phonetic context to compensate for place assimilation. Listeners heard two-word phrases such as pen pad and then saw two pictures, from which they had to select the one that depicted the phrase. Assimilation, lexical competitor environment and the phonological validity of assimilation context were all manipulated. Behavioral data showed an effect of context on the interpretation of assimilated segments. Analysis of 40 Hz gamma phase locking patterns identified a large distributed neural network including 16 distinct regions of interest (ROIs) spanning portions of both hemispheres in the first 200 ms of post-assimilation context. Granger analyzes of individual conditions showed differing patterns of causal interaction between ROIs during this interval, with hypothesized lexical and articulatory structures and pathways driving phonetic activation in the posterior superior temporal gyrus in assimilation conditions, but not in phonetically unambiguous conditions. These results lend strong support for the motor theory of speech perception, and clarify the role of lexical mediation in the phonetic processing of assimilated speech.  相似文献
