A meta-analytic review of cognitive processing therapy for adults with posttraumatic stress disorder

Numerous studies have demonstrated the efficacy of cognitive processing therapy (CPT) for treating posttraumatic stress disorder (PTSD). Two prior meta-analyses of studies are available but used approaches that limit conclusions that can be drawn regarding the impact of CPT on PTSD outcomes. The current meta-analysis reviewed outcomes of trials that tested the efficacy of CPT for PTSD in adults and evaluated potential moderators of outcomes. All published trials comparing CPT against an inactive control condition (i.e. psychological placebo or wait-list) or other active treatment for PTSD in adults were included, resulting in 11 studies with a total of 1130 participants. CPT outperformed inactive control conditions on PTSD outcome measures at posttreatment (mean Hedges’ g = 1.24) and follow-up (mean Hedges’ g = 0.90). The average CPT-treated participant fared better than 89% of those in inactive control conditions at posttreatment and 82% at follow-up. Results also showed that CPT outperformed inactive control conditions on non-PTSD outcome measures at posttreatment and follow-up and that CPT outperformed other active treatments at posttreatment but not at follow-up. Effect sizes of CPT on PTSD symptoms were not significantly moderated by participant age, number of treatment sessions, total sample size, length of follow-up, or group versus individual treatment; but, older studies had larger effect sizes and percent female sex moderated the effect of CPT on non-PTSD outcomes. These meta-analytic findings indicate that CPT is an effective PTSD treatment with lasting benefits across a range of outcomes.     

Structure and Measurement Invariance of Adult Romantic Attachment

Romantic attachment is a popular theory for explaining affect, cognition, and behavior in romantic contexts. This popularity has led to a surge of self-report measures assessing dimensions of attachment. In this study, we considered the ability of 2 common attachment measures, the Adult Attachment Questionnaire (AAQ) and the Experience in Close Relationships–Revised (ECR–R), to replicate the avoidant and anxious attachment factors. We also determined the degree of measurement invariance across, and mean differences between, genders and single and nonsingle individuals. Both the AAQ (N = 650) and the ECR–R (N = 1,271) successfully distinguished avoidant and attachment factors. The AAQ showed evidence for partial strong measurement invariance, whereas the ECR-R showed strict factorial invariance for both gender and relationship status. Gender differences were detected on both measures in a direction consistent with previous research, with males exhibiting higher levels of avoidant attachment (relative to females) and females exhibiting higher levels of anxious attachment (relative to males). Furthermore, when compared to individuals who were currently single, those in romantic relationships exhibited lower levels of avoidant tendencies. This research aligns with the notion that the AAQ and ECR–R reliably assess similar constructs, across genders and single and nonsingle individuals.     

Collective Efficacy as a Key Context in Neighborhood Support for Urban Youth

Neighborhood context, including the physical and social environment, has been implicated as important contributors to positive youth development. A transactional approach to neighborhood asserts that place and people are mutually constitutive; negative perceptions of place are intrinsically bound with negative portrayals of stigmatized groups, including youth. Adult perceptions of neighborhood youth may contribute to an increased sense of alienation and youth antisocial behavior. This study uses street‐intercept interviews with adults (N = 408) to examine the relationship between neighborhood conditions and adult support for neighborhood youth. A path model was used to examine the direct and indirect relationship of neighborhood constructs (safety, aesthetic quality, and walkability) on adult support for neighborhood youth. Neighborhood aesthetic quality and the walking environment were directly associated with adult support for youth, whereas perceived safety was indirectly associated. Collective efficacy partially explained these relationships. Findings support theorized relationships between people and places; improvements to neighborhood physical environment may directly impact resident adults’ perceptions of neighborhood young people.     

You can get here from there

During one of the several unsuccessful admission interviews I had before finally being admitted to a graduate program, an interviewer asked me what kind of research I would like to do as a psychologist. "I plan to validate the Rorschach" was my reply. "And what will you do if you find the Rorschach isn't valid?" was the interviewer's next question. I don't recall my answer but it was obviously inadequate because such an unlikely possibility hadn't occurred to me, and I wasn't admitted to that program. Looking back, it is very clear how one thing led to another so that instead of validating the Rorschach, I ended up exploring the contribution of genetic factors to stress ulcers in rats and children's personality.     

Composition of brain oscillations and their functions in the maintenance of auditory,visual and audio–visual speech percepts: an exploratory study

In the present exploratory study based on 7 subjects, we examined the composition of magnetoencephalographic (MEG) brain oscillations induced by the presentation of an auditory, visual, and audio-visual stimulus (a talking face) using an oddball paradigm. The composition of brain oscillations were assessed here by analyzing the probability-classification of short-term MEG spectral patterns. The probability index for particular brain oscillations being elicited was dependent on the type and the modality of the sensory percept. The maintenance of the integrated audio-visual percept was accompanied by the unique composition of distributed brain oscillations typical of auditory and visual modality, and the contribution of brain oscillations characteristic for visual modality was dominant. Oscillations around 20 Hz were characteristic for the maintenance of integrated audio-visual percept. Identifying the actual composition of brain oscillations allowed us (1) to distinguish two subjectively/consciously identical mental percepts, and (2) to characterize the types of brain functions involved in the maintenance of the multi-sensory percept.     

低收入女性的生活史特质与繁衍策略的关系

本研究探讨了单一性伙伴（n = 222）、两个以上性伙伴（n = 145）与无性伙伴（n = 106）三组低收入女性的长期配偶偏好、人生阅历、生活史特质与个人特征的关系。研究结果显示三组女性的配偶偏好趋于一致,繁衍策略的组别差异与人生阅历和所处环境具有较高相关,三组女性并不偏好特定类型的配偶。路径分析显示首次生育年龄直接预测配偶数量,受教育水平和初次性交时间对配偶数量与首次生育年龄之间的关系具有显著调节作用;女儿与父亲相处的时间可以预测初次性交年龄。研究结果显示父亲投资影响青少年性行为发展的时间表,人类繁衍的长期进化是性行为变化的根源     

Learning with arbitrary versus ecological conditioned stimuli: Evidence from sexual conditioning

Laboratory investigations of Pavlovian conditioning typically involve the association of an arbitrary conditioned stimulus (CS) with an unconditioned stimulus (US) that has no inherent relation to the CS. However, arbitrary CSs are unlikely to become conditioned outside the laboratory, because they do not occur often enough with the US to result in an association. Learning under natural circumstances is likely only if the CS has a preexisting relation to the US. Recent studies of sexual conditioning have shown that in contrast to an arbitrary CS, an ecologically relevant CS is resistant to blocking, extinction, and increases in the CS-US interval and results in sensitized responding and stronger second-order conditioning. Although the mechanisms of these effects are not fully understood, these findings have shown that signature learning phenomena are significantly altered when the kinds of stimuli that are likely to become conditioned under natural circumstances are used. The implications of these findings for an ecological approach to the study of learning are discussed.
