Negative emotions and coronary heart disease: Causally related or merely coexistent? A review

Negative emotions have been claimed to be a cause of coronary heart disease (CHD) as well as a consequence of cardiovascular disorders. Early case studies of cardiac disorders of soldiers in battle drew attention to the possibility that strong negative emotional states could cause CHD. Subsequent reports of reactions to natural disasters supported the notion that intense negative emotions could precipitate somatic disorders such as CHD. Since then, numerous studies have investigated relations between negative emotions and CHD. Over the years, retrospective studies have found, for example, that negative emotions are often present before the occurrence of CHD. Cross-sectional studies have indicated that symptoms of depression and anxiety are often present in CHD patients. Prospective studies have shown that the likelihood of CHD tends to be higher for people with negative emotions than for those without them. The main symptoms of negative emotional states that seem to be most closely associated with CHD are nervousness, getting easily upset, feeling fatigue, being indecisive, having sleep disturbances, being usually worried about something, and feeling that others would be better off if oneself were dead. Although the findings appear to support the notion of causal connections between negative emotions and CHD, they fail to provide conclusive proof of such relations. An alternative explanation that could also account for the findings is simply that negative emotions and CHD often coexist.     

Use of the Conners-Wells' Adolescent Self-Report Scale: Short Form with Psychiatric Outpatients

To provide information about the psychometric properties of the Conners-Wells' Adolescent Self-Report Scale: Short Form (CASS:S; C. K. Conners, 1997), the CASS:S was administered to 110 (46%) female and 130 (54%) male psychiatric outpatients between 13 and 17 years old. The coefficient s for the CASS:S Conduct Problems, Cognitive Problems, Hyperactivity, and ADHD Index scales were, respectively, .73, .80, .84, and .80. An exploratory maximum-likelihood factor analysis of the 18 item ratings from the Conduct, Cognitive, and Hyperactive scales identified two positively correlated dimensions; one was composed of the six items from the Conduct scale, and the other was composed of the 12 items from the Cognitive and the Hyperactive scales. The results were discussed as supporting the clinical utility of the CASS:S.     

Mutual regulation between infant facial affect and maternal touch in depressed and nondepressed dyads

The ability to regulate affect is important for later adaptive child development. In the first months of life, infants have limited resources for regulating their own affects (e.g. by gaze aversion), and for this reason they are dependent on external affect regulation from their parents. Previous research suggests that touch is an important means through which parents regulate their infants’ affects. Also, previous research has shown that post-partum depressed (PPD) mothers and nonclinical mothers differ in their touching behaviors when interacting with their infants. We examined the affect-regulating function of affectionate, caregiving and playful maternal touch in 24 PPD and 47 nonclinical mother-infant dyads when infants were four months old. In order to investigate the direction of effects and to account for repeated observations, the data were analysed using time-window sequential analysis and Generalized Estimating Equations. The results showed that mothers adapt their touching behaviors according to negative infant facial affect; thus, when the infant displays negative facial affect, the mothers were less likely to initiate playful touch and more likely to initiate caregiving touch. Unexpectedly, only in the PPD dyads, were the mothers more likely to initiate affectionate touch when their infants were displaying negative facial affect. Our results also showed that mothers use specific touch types to regulate infants’ negative and positive affects; infants are more likely to initiate positive affect during periods with playful touch, and more likely to terminate negative affect during periods with caregiving touch.     

Struggle with ultimate meaning: Nuanced associations with search for meaning,presence of meaning,and mental health

Struggle with ultimate meaning reflects concerns about whether one’s life has a deeper meaning or purpose. We examined whether this construct could be distinguished from presence of meaning in life and search for meaning. In two US samples – a web-based sample (N = 1047) and an undergraduate sample (N = 3978) – confirmatory factor analyses showed that struggle with ultimate meaning loaded on a factor that was distinct from but related to presence (negatively) and search (positively). Moderated regression analyses showed that people with low levels of presence combined with high levels of search for meaning were particularly likely to struggle with ultimate meaning. Additionally, when compared to presence and search, struggle with ultimate meaning related more strongly to depressive symptoms than presence or search. These results suggest that struggle with ultimate meaning represents a distinct component of how people grapple with meaning that has implications for mental health.     

NR3C1基因Bcl1多态性与青少年抑郁：压力性生活事件的调节作用

迄今,有关抑郁的基因×环境交互研究多数基于“单胺缺陷假说”,相对较少有研究以“HPA轴假说”为框架考察抑郁的遗传机制,且忽视了基因-环境相关的影响。本研究对1081名青少年进行追踪研究,考察NR3C1基因Bcl1多态性与压力性生活事件对抑郁的影响。结果发现,经历较多压力性事件时,C等位基因携带者的抑郁水平显著高于GG纯合子携带者;经历较少压力性事件时,不同基因型携带者的抑郁水平无差异。此外,通过区分独立性压力性事件和预测早期抑郁进一步排除了基因-环境相关的影响,在一定程度上验证了结果的可靠性。     

父母冲突对青少年抑郁的影响:认知反应性的中介作用

采用父母冲突儿童知觉量表(CPIC)、抑郁体验问卷(DEQ)、莱顿抑郁敏感指数量表(LEIDS)测量753名高中生,以便分析认知反应性在父母冲突与抑郁之间的中介作用。结果表明:(1)父母冲突显著正向预测认知反应性; 认知反应性显著正向预测青少年抑郁;(2)认知反应性在父母冲突与青少年抑郁之间具有完全中介作用。因此,认知反应性作为中介变量,父母冲突通过认知反应性对青少年抑郁具有稳定的间接作用。     

Media experiences and associations with mental health among the bereaved of the MH17‐disaster: A latent profile analysis

Research has shown that the amount of media exposure is associated with post‐event mental health problems. Whether bereaved individuals have negative experiences with media reports and whether they are associated with post‐event mental health is unclear. This study evaluated these experiences and associations following the MH 17‐disaster. How media reports were experienced (nine topics, modified MAS ), depression symptoms (QIDS ‐SR ), functional problems (WSAS ) and event‐related coping‐self‐efficacy (CSE ) were assessed about one year post‐disaster (May‐August 2015) among Dutch bereaved (N  = 152). A substantial minority reported negative experiences such as reports made me angry (30%) and made me sad (48%). Latent profile analysis with symptoms, problems and coping self‐efficacy as indicators, identified four classes of post‐disaster mental health: a Well‐functioning^{(class 1)}, 35.1%; a Mild‐problems^{(class 2)}, 30.4%; a Sub‐clinical^{(class 3)}, 27.0%; and a Clinical^{(class 4)}, 7.4%. Differences in symptoms, problems and coping self‐efficacy levels between classes were large according to Cohen's d s. Multivariate logistic regression (MLR ) showed that the Clinical^{(class 4)} compared to the Well‐functioning^{(class 1)}, more often that felt that reports strongly “embarrassed me,” “made me feel sad,” “filled me with fear” and “served as a magnifying glass.” Future research should assess opportunities and effects of limiting media consumption.     

UNDERSTANDING THE CONNECTION BETWEEN ATTACHMENT TRAUMA AND MATERNAL SELF‐EFFICACY IN DEPRESSED MOTHERS

Maternal self‐efficacy predicts sensitive and responsive caregiving. Low maternal self‐efficacy is associated with a higher incidence of postpartum depression. Maternal self‐efficacy and postpartum depression can both be buffered by social support. Maternal self‐efficacy and postpartum depression have both been linked independently, albeit in separate studies, to the experience of violent trauma, childhood maltreatment, and spousal abuse. This study proposed a model in which postpartum depression mediates the relation between attachment trauma and maternal self‐efficacy, with emotional support as a moderator. Participants were 278 first‐time mothers of infants under 14 months. Cross‐sectional data were collected online. Mothers completed questionnaires on attachment trauma, maternal self‐efficacy, postpartum depression, and emotional support. A moderated mediation model was tested in a structural equation modeling framework using Mplus’ estimate of indirect effects. Postpartum depression fully mediated the relation between trauma and maternal self‐efficacy. Emotional support moderated only the pathway between postpartum depression and maternal self‐efficacy. Attachment trauma's implications for maternal self‐efficacy should be understood in the context of overall mental health. Mothers at the greatest risk for low maternal self‐efficacy related to attachment trauma also are those suffering from postpartum depression. Emotional support buffered mothers from postpartum depression, though, which has implications for intervention and future research.
