Trauma‐Related Guilt Mediates the Relationship between Posttraumatic Stress Disorder and Suicidal Ideation in OEF/OIF/OND Veterans

Posttraumatic stress disorder (PTSD) and trauma‐related guilt are risk factors for suicidal ideation (SI) in veterans. Components of trauma‐related guilt were examined as serial mediators of the relationship between PTSD and SI. In a sample of 53 OEF/OIF/OND combat veterans, PTSD had an indirect effect on SI through a serial mediation chain of guilt cognitions, distress, and global guilt, suggesting that trauma‐related guilt via cognitions, distress, and global guilt is a pathway from PTSD to SI. Attention should be given to assessing and addressing trauma‐related guilt in veterans experiencing PTSD to prevent SI.     

Deadly Force and Deadly Outcome: Examining the Officer,Suspect, and Situational Characteristics of Officer-Involved Shootings

ABSTRACT

Police use-of-force in general, and police use of deadly force in particular, has been at the forefront of national media attention in recent years. Despite this visibility, scholarly attention to the complexities and nuances of the dynamics at play that lead to fatal and non-fatal outcomes for suspects involved in these encounters has been limited. As such, the current study draws from data collected from 2015 to 2018 in the state of Texas to examine the officer-, suspect-, and situational-level correlates and predictors of suspect death resulting from being involved in an officer-involved shooting. Bivariate results suggest that officer race, suspect race, the suspect being armed with a deadly weapon, and the officer responding to a suspicious activity call are significantly associated with suspect death versus being injured in an officer-involved shooting. More rigorous multivariate results reveal that the situational context (i.e., the suspect being armed with a deadly weapon and the incident resulting from a suspicious activity call) is particularly relevant for predicting the lethality of an officer-involved shooting for the suspect. Study limitations and directions for future research are also discussed.     

Side Streets and U-Turns: Effects of Context Switching,Direction Switching,and Factor Switching on Interitem Correlations and Misresponse Rates

This study tested implications of the context switching perspective proposed by Hamby, Ickes, and Babcock (2016 Hamby, T., Ickes, W., &; Babcock, M. (2016). Evidence for context switching in the effects of average item length and item-length variability on internal consistency. Journal of Personality Assessment, 98, 491–502. doi:10.1080/00223891.2016.1147044[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Using trained raters to assess the amount of reframing required to interpret the meaning of the subsequent (second) item within all adjacent item pairs, we first established that this process variable could be measured reliably. Then, in the data for 18 personality measures drawn from 3 individual-difference domains, we found that the amount of reframing (i.e., context switching) needed to interpret successive items predicted both lower interitem correlations and a greater percentage of misresponders. Similarly, item pairs that were mismatched in “directional” wording also predicted both lower interitem correlations and more misresponders. Finally, item pairs representing different factors predicted lower interitem correlations. Although the effects of direction switching and factor switching were partially mediated by the amount of reframing required, they remained significant even when the mediating effect of reframing was statistically controlled. These results indicate that interpreting the meaning of test items is a task for which the level of difficulty can vary with each successive item, as a function of how the current item compares to the previous item in aspects such as its context generality or specificity, directional wording, and content domain.     

Quantifying latent social motivation and its associations with joint attention and language in infants at high and low likelihood for autism spectrum disorder

Social motivation—the psychobiological predisposition for social orienting, seeking social contact, and maintaining social interaction—manifests in early infancy and is hypothesized to be foundational for social communication development in typical and atypical populations. However, the lack of infant social-motivation measures has hindered delineation of associations between infant social motivation, other early-arising social abilities such as joint attention, and language outcomes. To investigate how infant social motivation contributes to joint attention and language, this study utilizes a mixed longitudinal sample of 741 infants at high (HL = 515) and low (LL = 226) likelihood for ASD. Using moderated nonlinear factor analysis (MNLFA), we incorporated items from parent-report measures to establish a novel latent factor model of infant social motivation that exhibits measurement invariance by age, sex, and familial ASD likelihood. We then examined developmental associations between 6- and 12-month social motivation, joint attention at 12–15 months, and language at 24 months of age. On average, greater social-motivation growth from 6–12 months was associated with greater initiating joint attention (IJA) and trend-level increases in sophistication of responding to joint attention (RJA). IJA and RJA were both positively associated with 24-month language abilities. There were no additional associations between social motivation and future language in our path model. These findings substantiate a novel, theoretically driven approach to modeling social motivation and suggest a developmental cascade through which social motivation impacts other foundational skills. These findings have implications for the timing and nature of intervention targets to support social communication development in infancy.

Highlights

• We describe a novel, theoretically based model of infant social motivation wherein multiple parent-reported indicators contribute to a unitary latent social-motivation factor.
• Analyses revealed social-motivation factor scores exhibited measurement invariance for a longitudinal sample of infants at high and low familial ASD likelihood.
• Social-motivation growth from ages 6–12 months is associated with better 12−15-month joint attention abilities, which in turn are associated with greater 24-month language skills.
• Findings inform timing and targets of potential interventions to support healthy social communication in the first year of life.
