A Preliminary Study of DSM–5 PTSD Symptom Patterns in Veterans by Trauma Type

The all-volunteer status of the military, combined with an increasing desire to employ individuals with the requisite knowledge, skills, and abilities to perform highly sophisticated tasks, has intensified competition between military and private sector organizations attempting to attract and retain qualified personnel. In an effort to remain competitive with employers in the private sector labor market, U.S. military organizations have directed their attention to various personnel support programs aimed at meeting the needs of servicemembers and contributing to their overall quality of life. More specifically, these military services have focused on the development and validation of conceptual models that link quality of life to desired military outcomes, including personnel retention, readiness, and performance. This study extended recent quality of life research efforts by determining the applicability of a model developed and validated for Navy personnel to another branch of the military, the U.S. Marine Corps. Structural equation modeling results suggested that the Navy model provided an adequate fit to the Marine Corps data for each of the subgroups considered. Results and implications are discussed.     

Parenting and the dysregulation profile predict executive functioning in children with acquired brain injury

Background: Children with acquired brain injury (ABI) present with high rates of psychological disorders commonly accompanied by deficits in hot and cold executive functions (EFs). Impairments in EFs have been reported to precede mental health problems. Moreover, children who are vulnerable to developing mental health problems in adulthood frequently present with a dysregulation profile in childhood, characterized by impairments in cognitive, behavioral and emotional regulation. Objective: To identify profiles of behaviors associated with impairment in hot and cold EFs and compare injury factors, environmental stressors and dysregulation profile between them. Methods: A latent profile analysis was conducted with 77 children with ABI aged between 6 and 12. Injury factors, child IQ, environmental stressors and the dysregulation profile were compared between these behavioral profiles. Logistic regressions were conducted to predict profile membership. Results: Two profiles were identified: Profile M, with mild deficits (1–2 SD above the mean) in working memory and social skills, and profile C, presenting clinically significant deficits (2–3 SD above the mean) in shift, initiate, working memory, planning and social skills and mild deficits in inhibit, emotional control and task monitor. Proximal environmental stressors (dysfunctional parenting practices, parental stress, parent’s executive dysfunction, anxiety-trait, and depressive symptoms) and dysregulation symptoms predicted profile membership, whereas injury factors, child IQ and distal environmental stressors did not. Conclusion: Following ABI, children with profile C are at risk of mental health problems and present with more proximal stressors. The dysregulation profile may be useful as a proxy for risk for later mental health problems in children with ABI.     

Sensory Processing Differences in Children Diagnosed With Tourette's Disorder

The objectives of this research were to determine whether sensory processing differences existed in children between the ages of 5 and 10 years diagnosed with Tourette's disorder and to examine whether further differences existed if these children had an additional diagnosis of Attention Deficit Hyperactivity Disorder. The Short Sensory Profile was completed by caregivers for 75 children with Tourette's disorder, 47 who were also diagnosed with Attention Deficit Hyperactivity Disorder. Differences in sensory processing were identified in the total sample. More significant differences were found in the group of children with dual diagnoses, especially in the area of auditory processing.     

Evolution of Gonadal Axis After Sex Reassignment Surgery in Transsexual Patients in the Spanish Public Health System

ABSTRACT

Although the effects of hormone therapy on cardiovascular risk factors and bone metabolism have been studied, data are lacking on the gonadotropin profile after gonadectomy in the sex reassignment process (SRP). Accordingly, whether measurement of the gonadotropin profile is useful in order to adjust the postsurgical dose of gonadal hormones is unknown. We studied the evolution of LH, FSH, prolactin, testosterone, and estradiol in 50 transsexual persons, 41 male-to-female transsexuals (MtF) and 9 female-to-male transsexuals (FtM), following a proto-colized regimen of hormone therapy for 12–24 months before and after genitoplasty. The increase in gonadotropins after surgery was greater in the FtM than in the MtF (66% vs. 50%), with the increase continuing more than one year after surgery. No variable was significantly associated with this different level of gonadotropins.     

Are People Mindful in Different Ways? Disentangling the Quantity and Quality of Mindfulness in Latent Profiles and Exploring their Links to Mental Health and Life Effectiveness

We sought to disambiguate the quantitative and qualitative components of mindfulness profiles, examine whether including ‘nonattachment’ as a subcomponent of mindfulness alters the profiles, and evaluate the extent to which the person‐centred approach to understanding mindfulness adds predictive power beyond a more parsimonious variable‐centred approach. Using data from a nationally representative sample of Americans (N = 7884; 52% female; Age: M = 47.9, SD = 16), we utilized bifactor exploratory structural equation modelling and latent profile analysis to separate the level and shape of previously identified profiles of mindfulness (Pearson, Lawless, Brown, & Bravo, 2015 ). Consistent with past research, we identified a judgmentally observing profile and a non‐judgmentally aware group, but inconsistent with past research, we did not find profiles that showed high or low levels on all specific aspects of mindfulness. Adding nonattachment did not alter the shape of the profiles. Profile membership was meaningfully related to demographic variables. In models testing the distinctive predictive utility of the profiles, the judgmentally observing profile, compared to the other profiles, showed the highest levels of mental ill‐health, but also the highest levels of life satisfaction and effectiveness. We discuss the implications of our study for clinical interventions and understanding the varieties of mindfulness. Copyright © 2017 European Association of Personality Psychology     

A latent profile analysis of the Five Factor Model of personality: Modeling trait interactions

Interactions among the dimensions of the Five Factor Model (FFM) have not typically been evaluated in mental health research, with the extant literature focusing on bivariate relationships with psychological constructs of interest. This study used latent profile analysis to mimic higher-order interactions to identify homogenous personality profiles using the FFM, and also examined relationships between resultant profiles and affect, self-esteem, depression, anxiety, and coping efficacy. Participants (N = 371) completed self-report and daily diary questionnaires. A 3-profile solution provided the best fit to the data; the profiles were characterized as well-adjusted, reserved, and excitable. The well-adjusted group reported better psychological functioning in validation analyses. The reserved and excitable groups differed on anxiety, with the excitable group reporting generally higher anxiety than the reserved group. Latent profile analysis may be a parsimonious way to model personality heterogeneity.     

Establishment and replication of emotion regulation profiles: implications for psychological health

Background and Objectives: A promising method of capturing the complex nature of emotion regulation is to assess composite profiles of regulation (i.e., default pattern of regulation across multiple strategies). However, it remains unclear whether regulatory profiles demonstrate consistency across samples and in relation to mental health. Design: Two studies are presented here. Both utilized a cross-sectional design, and the second study presents a replication of the first. Method: Both studies utilized self-report data from independent undergraduate samples to perform latent profile analyses of emotion regulation use. Results: Studies 1 and 2 demonstrated evidence for four replicable regulatory profiles: Adaptive, Accepting (with or without Suppression), Non-accepting, and Maladaptive. Profiles were also related to symptoms of depression and anxiety, such that those consistently relying on adaptive strategies reported lower symptoms than those relying more heavily on maladaptive strategies. Conclusions: These findings clarify previous work which tied regulatory profiles to psychological health by extending a person-centered approach to understanding the ways in which individuals regulate their emotions.
