Trajectories of Response to Treatment for Posttraumatic Stress Disorder

Research on the predictors of response to cognitive-behavioral treatments for PTSD has often produced inconsistent or ambiguous results. We argue this is in part due to the use of statistical techniques that explore relationships among the entire sample of participants rather than homogeneous subgroups. Using 2 large randomized controlled trials of Cognitive Processing Therapy (CPT), CPT components, and Prolonged Exposure, we employed growth mixture modeling to identify distinct trajectories of treatment response and to determine the predictors of those trajectories. We determined that the participants’ trajectories could be best represented by 2 latent classes, which we subsequently labeled responders (87% of the sample) and nonresponders (13% of the sample). Notably, there was not a separate class for partial responders. Assignment to the nonresponder class was associated with receiving the written accounts (WA) component of CPT, a pretreatment diagnosis of major depression (MDD), and more pretreatment hyperarousal symptoms. Thus, it appears that some individuals do not benefit from merely writing about their trauma and processing it with the therapist; they may also need to engage in cognitive restructuring to successfully ameliorate their symptoms. Additionally, those who meet criteria for MDD or have high levels of hyperarousal at the onset of treatment might require additional treatment or support.     

Regulatory competence and social communication in term and preterm infants at 12 months corrected age. Results from a randomized controlled trial

Temperamental regulatory competence and social communication in term and preterm infants at 12 months corrected age was studied in a randomized controlled intervention trial aimed at enhancing maternal sensitive responsiveness. Surviving infants <2000 g from a geographically defined area were randomized to an intervention (71) or a control group (69), and compared with term infants (74). The intervention was a modified version of the "Mother-Infant Transaction Program". Regulatory competence was measured with the Infant Behavior Questionnaire, and social communication with the Early Social Communication Scales. Preterm intervention infants with low regulatory competence had higher responding to joint attention than preterm control infants. A sensitizing intervention may moderate the association between temperament and social communication, and thus allow an alternative functional outlet for preterm infants low in regulatory competence. The finding may have implications for conceptualizations of the role of early sensitizing interventions in promoting important developmental outcomes for premature infants.     

Not just another face in the crowd: Detecting emotional schematic faces during continuous flash suppression

To test whether threatening visual information receives prioritized processing, many studies have examined visual search for emotional schematic faces. Still, it has remained unclear whether negative or positive schematic faces are processed more efficiently. We used continuous flash suppression, a variant of binocular rivalry, to render single emotional schematic faces invisible and measured whether negative or positive faces have an advantage in accessing awareness. Across three experiments, positive faces were detected more quickly than negative faces. A fourth experiment indicated that this positive face advantage was unrelated to the valence of the face stimuli but due to the relative orientation of the mouth curvature and the face contour. These findings demonstrate the impact of configural stimulus properties on perceptual suppression during binocular rivalry and point to a perceptual confound present in emotional schematic faces that might account for some ambiguous results obtained with schematic face stimuli in previous studies.

The bonnie baby: experimentally manipulated temperament affects perceived cuteness and motivation to view infant faces

Attractive individuals are perceived as having various positive personality qualities. Positive personality qualities can in turn increase perceived attractiveness. However, the developmental origins of the link between attractiveness and personality are not understood. This is important because infant attractiveness (‘cuteness’) elicits caregiving from adults, and infant personality (‘temperament’) shapes caregiving behaviour. While research suggests that adults have more positive attitudes towards cuter infants, it is not known whether positive infant temperament can increase the perception of infant cuteness. We investigated the impact of experimentally established infant temperament on adults' perception of cuteness and desire to view individual faces. Ataseline, adults rated the cuteness of, and keypressed to view, images of unfamiliar infants with neutral facial expressions. Training required adults to learn about an infant's ‘temperament’, through repeated pairing of the neutral infant face with positive or negative facial expressions and vocalizations. Adults then re‐rated the original neutral infant faces. Post‐training, there were significant changes from baseline: infants who were mostly happy were perceived as cuter and adults expended greater effort to view them. Infants who were mostly sad were not perceived as cuter and adults expended less effort to view them. Our results suggest that temperament has clear consequences for how adults perceive ‘bonnie’ babies. Perception of infant cuteness is not based on physical facial features alone, and is modifiable through experience.     

Parent–Child Cultural Value Gaps and Depressive Symptoms Among Mexican American Youth

Cultural value gaps between Mexican American parents and their children are hypothesized to place youth at risk for poor mental health outcomes. While most studies examine these gaps on broad measures of acculturation, the present study examined value gaps in affiliative obedience, a cultural value that has at its core the belief that respect and deference must be shown to parents and adults. The present study hypothesized that adolescents would exhibit greater depressive symptoms when youth demonstrated lower levels of affiliative obedience than their mothers. Moreover, we examined whether gender, nativity status, and age predicted cultural value gaps and moderated the relationship between gaps and depressive symptoms. These questions were evaluated in a school-based sample of 159 Mexican American families whose children were either US born (n = 82) or foreign-born (n = 77). Twenty-five percent of the sample demonstrated a cultural value gap where youth endorsed lower levels of affiliative obedience than their parents, and this group reported the greatest depressive symptoms. Age moderated this relationship, and the greatest association between cultural value gaps and depression was found among the older group of early adolescents.
