Cognitive behavioral therapies (CBT) for youth with anxiety, traumatic stress, and depression have demonstrated strong effects in individual studies and meta-analyses. Relatively more attention has been given to posttreatment effects, though, and assessment of follow-up effects has been limited at the meta-analytic level. The current meta-analysis aimed to (a) examine the effects of youth CBT at posttreatment, 1-month, 3-month, 6-month, 1-year, and long-term (2 + years) follow-up as well as (b) identify research-related variables (e.g., measure respondent type) that relate to effects. Using a random effects model across 110 child and adolescent CBT groups, within-group effect sizes were large at posttreatment (g = 1.24) and from 1-month through long-term follow-up (g = 1.23–1.82), and effect sizes did not significantly differ by treatment target (i.e., anxiety, traumatic stress, depression). However, availability of outcome data for effect sizes diminished across later follow-up assessments. Moreover, effect sizes were significantly associated with outcome respondent type across assessment timing, with outcome measures from caregiver and youth respondents associated with smaller effect sizes (B = -0.97, p < 0.001) relative to outcome measures that were evaluator-reported. Results provide initial support for the durability of treatment effects for youth CBTs and highlight the importance of some confounding variables. Implications for improving treatment research standards and prioritizing assessment of long-term follow-up assessment are discussed. 相似文献

Both reward sensitivity and impulsivity are related to the development and course of bipolar spectrum disorders (BSDs) and have been implicated in other disorders and negative functional outcomes such as substance abuse, obesity, suicidal behaviors, and risk-taking. Furthermore, according to the transactional component of the Behavioral Approach System (BAS)/reward hypersensitivity theory of BSDs, people with reward hypersensitivity should experience more BAS-relevant events, and thus, are more vulnerable to mood symptoms and episodes via stress generation. Impulsivity may exacerbate stress generation in individuals at risk for BSDs based on exhibiting reward hypersensitivity. The current study examined whether impulsivity explained the generation of stress and subsequent mood symptoms beyond what is explained by reward sensitivity alone. Participants were 131 Moderate BAS and 216 High BAS sensitivity adolescents (M = 18.43 years, SD = 1.40), who completed baseline measures of reward sensitivity and impulsivity, as well as follow-up measures of life events and mood symptoms. Results from linear regression analyses indicated that higher baseline impulsivity predicted behavior-dependent, but not behavior-independent, life events. Furthermore, path analyses suggested that the effect of BAS group on depression symptoms at next follow-up was partly explained via the indirect effect of impulsivity and negative behavior-dependent life events. We did not find these effects for behavior-independent or positive-dependent events or for prediction of hypomanic symptoms. The findings suggest that impulsivity may account for stress generation of negative events that precede depression. 相似文献

Recent research suggests that the stress-sleep relationship is mediated by pre-sleep arousal (PSA) and that cognitive arousal has a stronger mediating effect than somatic arousal; however, this has not been directly tested. Using multilevel moderated mediation, we compared the effects of cognitive arousal and somatic arousal within the stress-sleep relationship. We also assessed whether two forms of repetitive negative thought—rumination and worry—are similarly involved in the stress-sleep relationship. Data was collected from 178 participants across the United States via an online platform. Participants completed baseline self-report surveys examining rumination tendencies and worry tendencies. Over the course of 2 weeks, participants completed daily questionnaires assessing daily stress, PSA, and sleep quality. Results indicated that indirect effects from stress to sleep quality via PSA were statistically significant at low and high levels of rumination and worry, and people at high levels of rumination and worry had stronger relationships between stress and PSA. Across all models, cognitive arousal consistently accounted for more of the variance in the stress-sleep relationship as compared to somatic arousal. Implications for the cognitive behavioral treatment of insomnia are discussed. 相似文献

We examined the relationship between suicidal ideation (SI) and the depressed mood, life stress and parenting styles in children. A large‐scale survey was conducted including 5328 children from 65 elementary schools in Taiwan. SI was measured by asking children if any suicidal thoughts had occurred in the previous month. A series of regression models was analysed separately for male and female students. Compared with boys, girls demonstrated a higher proportion of SI. Among boys, SI was significantly associated with a high level of perceived environmental stress (adjusted odds ratio [aOR] = 2.61), a high degree of depressed mood (aOR = 2.39), authoritative (aOR = 1.72) and authoritarian (aOR = 2.53) parenting styles and two or more life‐stress events (aOR = 1.45). A high level of perceived environmental stress (aOR = 2.09), a high degree of depressed mood (aOR = 2.89) and an authoritarian parenting style (aOR = 1.76) were significantly associated with the SI in girls. Gender‐specific interventions aimed at preventing SI must enhance support systems at school and at home, particularly for students who suffer from a high degree of stress and depressed mood, and are subjected to an authoritarian parenting style. 相似文献

Negative mood regulation expectancies (NMRE) represent people's confidence that they can alleviate their negative affect or induce a positive emotional state through thought or action. NMRE predict coping behaviour and mood outcomes for individuals under stress. Since 1990, much research documents the reliability and validity of the English language Negative Mood Regulation (NMR) scale as a measure of NMRE. The current research reports two studies developing a Chinese language translation of the NMR (NMR‐C) scale that goes beyond literal translation to be a culturally sensitive measure of NMRE in China. In Study 1, 713 college students from both a major city and a rural setting in China were surveyed. Data support the resulting 32‐item NMR‐C's reliability (alpha = .88) and validity. The NMR‐C showed both direct and indirect links to depression and anxiety; coping mediated the indirect effect. In Study 2, 331 prison police officers in three Chinese provinces participated. NMRE buffered the effect of high role pressure, moderating the relationship between prison police role stress and job engagement. Results of the two studies support the reliability and validity of the Chinese language NMR scale and parallel results found with measures of NMRE in the West and in other Asian countries. 相似文献

Given the potentially harmful effects of parenting stress on parents, children, and their relationship, it is critical to have a reliable and valid measure of parenting stress in clinical and community samples. The Family Strain Index (FSI) is a brief questionnaire designed to measure stress and demand on parents of children with ADHD. The present study is the first to evaluate the psychometric properties of scores on the FSI in a general community sample. Parents (89% mothers) of 550 preschool children (aged 2–5 years; 50% boys) sampled through 17 kindergartens located in Danish cities and villages completed the FSI, the ADHD Rating Scale (RS)‐IV Preschool Version, and a background questionnaire. FSI scores were characterized by restricted range and floor effects. The scale's construct validity was not supported and the measurement repeatability after 1 month was low. The scale did have convergent validity as levels of parenting stress were associated with perceived ADHD behavior in off‐spring, but overall, results did not encourage the use of the FSI as a measure of parenting stress in the general population. Measures that include more normative events may be more appropriate when attempting to capture parenting stress in general community samples. 相似文献

Pediatric medical traumatic stress (PMTS) is common among injured/ill children and is associated with elevated distress, treatment non‐adherence, and poor health outcomes. As survivorship of life‐threatening pediatric injury and illness continues to increase alongside rapid medical advancements, rates of PMTS and negative sequelae are expected to grow; however, research on prevention and treatment of PMTS is limited. The current study sought to systematically review the literature using a developmental framework to highlight research gaps. Sixteen peer‐reviewed studies were identified via a systematic literature search. Consistent with best practices for treatment of childhood trauma, caregiver involvement and CBT principles served as the foundation for most interventions. All studies reported improvements in PMTS; however, among the most methodologically rigorous, few found statistically superior reductions in PMTS between intervention and control groups. While many studies focused on a specific developmental stage and discussed developmental considerations, others took a “one‐size‐fits” approach. Interventions that demonstrated the most promising findings were online, self‐guided, or time‐limited. Future research would benefit from expanding diversity of participants, continuing to evaluate novel delivery methods, and integrating developmental considerations along with trauma‐informed care (TIC) approaches, given their useful framework for understanding child traumatic stress responses and avenues for prevention and treatment. 相似文献

Objective: Habitual use of emotion regulation strategies may influence physical health. We examined whether the tendencies to employ cognitive reappraisal and suppression were associated with health biomarkers, and whether stress and sleep quality mediated these associations. Design & main outcome measures: Using data from the Biomarkers substudy (n?=?1255) of the national Midlife in the U.S. Study, we tested the hypothesis that there would be indirect, but not direct, associations of cognitive reappraisal and suppression to biomarker indicators of multisystem physiological dysregulation, that is, allostatic load (AL). We computed the proportion of biomarkers in the highest risk quartile within seven biological systems, and summed these scores to compute AL. Associations with the biological systems were also examined separately.Results: Neither reappraisal nor suppression was directly associated with AL or biomarker function in the seven biological systems. Suppression was indirectly associated with higher AL and greater dysregulation in the inflammatory, metabolic, and hypothalamic-pituitary-adrenal systems via its relations to stress and sleep, p?<?0.05. Reappraisal was indirectly associated with lower AL and less metabolic and inflammatory dysregulation, ps<0.05.Conclusions: Suppression and reappraisal may have different downstream health effects via stress, sleep, and biomarker expression, suggesting malleable emotion regulation strategies may be an important intervention target. 相似文献

自尊稳定性(自尊在短期内波动的幅度)是一种具有重要心理功能的人格特质, 它既不同于自尊水平, 也区别于情境性自尊, 但在理论和测量上却与后两者具有密不可分的联系。然而, 由于目前人们对于自尊稳定性的认知神经机制知之甚少, 所以并不清楚它与自尊水平在生理机制上的关系是什么, 更不了解它会如何调节情境性自尊。鉴于此, 本研究计划将自尊稳定性、自尊水平和情境性自尊置于整合的认知神经加工模型(神经内分泌-脑-行为)之中, 通过融合心理测量、脑成像与应激诱发等多种技术指标, 力争全方位、多角度揭示自尊稳定性的认知神经机制, 及其与自尊水平、情境性自尊间的区别和联系。 相似文献
