Obsessive Compulsive Symptoms Predict Posttraumatic Growth: A Longitudinal Study

Although posttraumatic growth (PTG) has received growing attention, the relationship between PTG and distress remains unclear. This longitudinal study examines the relationship between posttraumatic obsessive-compulsive (OC) symptoms and PTG. Israeli veterans were followed over 17 years using self-report questionnaires of OC symptoms, posttraumatic stress disorder (PTSD), and PTG. Hierarchical regression analyses demonstrated that OC symptoms predicted PTG, even when initial PTG levels and PTSD symptoms were controlled for in the combatants group. These preliminary findings suggest that OC symptoms may play an important role in facilitating psychological growth. Future research is warranted to explore the mechanisms responsible for this relationship.     

失眠的自助式认知行为治疗元分析:疗效、影响因素及证据评价

通过元分析评估自助式失眠认知行为治疗的疗效,考察疗效影响因素,并评价证据质量。元分析共纳入35篇文献,研究发现:(1)自助式失眠认知行为治疗在治疗结束时对睡眠效率、入睡潜伏期、入睡后醒来时长、睡眠总时间、睡眠质量、抑郁和焦虑的效果量分别为0.66、-0.52、-0.47、0.20、0.34、-0.32和-0.33。(2)自助式失眠认知行为治疗与面对面失眠认知行为治疗疗效同等;自助式失眠认知行为治疗疗效显著优于最小化治疗和药物治疗。(3)共病情况与支持形式对疗效有显著影响。证据质量评价表明睡眠效率、入睡后醒来时长、睡眠总时间、抑郁和焦虑5项指标的证据质量为中等,真实值可能接近于估计值;入睡潜伏期与睡眠质量为低,真实值与估计值可能存在着差异。     

父母心理控制与ODD症状儿童抑郁、攻击行为的关系

以北京市、山东省和云南省14所小学中的340名有对立违抗障碍(Oppositional Defiant Disorder, ODD)症状的儿童及其158名班主任为被试, 收集了儿童自己填写的父母心理控制、自尊、抑郁量表, 班主任评估的儿童攻击行为量表, 用以考察父亲与母亲心理控制对ODD症状儿童抑郁、攻击行为的不同影响, 以及自尊在其中的中介作用和儿童性别的调节作用。结果发现:(1)与有ODD症状的女孩相比, 具有ODD症状的男孩人数更多, 抑郁、攻击行为问题更为严重, 自尊也更差;(2)父亲对男孩的心理控制显著多于女孩, 而母亲对男孩、女孩的心理控制没有显著差异;(3)父亲和母亲心理控制与ODD症状儿童的抑郁、攻击行为都呈显著正相关且父亲心理控制能显著预测儿童的抑郁和攻击行为, 而母亲心理控制能显著的预测攻击行为;(4)自尊在父亲心理控制与ODD症状儿童的抑郁、母亲心理控制与儿童的攻击行为之间均起部分中介作用, 在父亲心理控制与儿童的攻击行为、母亲心理控制与儿童的抑郁之间均起完全中介作用。     

Emotion regulation and mood brightening in daily life vary with depressive symptom levels

Naturalistic studies of emotional reactivity in depression have repeatedly found larger decreases in negative affect (NA) among depressed individuals in response to daily positive events. This so-called mood-brightening (MB) effect represents a theoretical and empirical oddity. The current study is a secondary analysis investigating whether the MB effect is moderated by spontaneous use of emotion regulation strategies, which have been implicated in the maintenance and modulation of NA in prior work. Participants (N?=?95) representing a large spectrum of depressive symptom severity reported their experiences of NA and the occurrence of positive events in daily life over the course of seven days using the experience sampling method. Our findings replicate and build upon those of prior studies relating to the MB effect in the following ways: (1) we observed the MB effect for specific negative emotions of sadness, anger, anxiety; and (2) we found evidence that the MB effect is moderated by spontaneous use of rumination, distraction, and expressive suppression, which have been shown to enhance or dampen NA. The role of emotion regulation strategies in daily emotional reactivity to pleasant events is discussed.     

Brain Function Associated with Cooccurring Trauma and Depression Symptoms in College Students

The goal of this pilot study was to determine if functional brain differences are present among individuals with high and low cooccurring trauma and depression symptoms. This pilot study examined how the P300 latency component of event-related potentials (ERPs), measured using electroencephalography (EEG) while participants performed a go/no-go task, might be associated with cooccurring self-report of trauma and depression symptoms in a sample of college students (N = 38). Alpha-corrected independent sample t tests revealed statistically significant differences in ERP P300 peak latencies between those in the high cooccurring trauma and depression symptoms group (n = 12) and those in the low group (n = 26) for all 3 midline electrode sites (Fz, Cz, and Pz). This pilot study provides preliminary evidence of differential brain functioning in individuals experiencing cooccurring trauma and depression symptoms. Accordingly, these findings support future research examining brain functioning in cooccurring symptoms.     

Violent obsessions are associated with suicidality in an OCD analog sample of college students

The picture of suicide in obsessive-compulsive disorder (OCD) is unclear because previous research did not uniformly control for depressive symptoms when examining the relationship between OCD and suicidality. Specific links between OC symptom dimensions and suicidality were also not adequately studied. As such, we investigated specific associations between OC symptom dimensions and suicidality, beyond the contribution of depressive symptoms, in an OCD analog sample of college students, a group traditionally at risk for suicide. One hundred and forty-six college students (103 females; 43 males) who exceeded the clinical cut-off for OC symptoms on the Obsessive-Compulsive Inventory, Revised (OCI-R) were recruited. Participants completed an online questionnaire containing measures that assessed suicidality and OC and depressive symptom severity. Total OC symptom severity, unacceptable thoughts, and especially violent obsessions exhibited significant positive zero-order correlations with suicidality. However, analyses of part correlations indicated that only violent obsessions had a significant unique association with suicidality after controlling for depressive symptoms. Our findings support the hypothesis that violent obsessions have a specific role in suicidality beyond the influence of depressive symptoms in an OCD analog sample of college students. A strong clinical focus on suicide risk assessment and safety planning in college students reporting violent obsessions is therefore warranted. Future related research should employ longitudinal or prospective designs and control for other possible comorbid symptoms in larger and more representative samples of participants formally diagnosed with OCD in order to verify the generalizability of our findings to these groups.
