Seventy-four of them participated in the AAI at T1. At T2, parents completed a questionnaire assessing their infants' social-emotional development.nnRESULTS: The DRS-8 has two highly correlated dimensions, i.e., lapses in the monitoring of reasoning (four items) and discourse (four items). A confirmatory factor analysis supported a bifactor structure of the instrument, showing good fit indices and internal consistency (ω = 0.87). The DRS-8 was significantly correlated with U/d states of mind on the AAI, r(72) = 0.28, p = .016, and demonstrated excellent construct validity. Significant indirect effects of the DRS-8 were found in the associations between childhood trauma and psychological symptoms, and between parental trauma and infant social-emotional development.nnCONCLUSIONS: The DRS-8 appears to be a promising self-report measure of U/d states of mind showing criterion validity with the AAI.},

	  The previously observed heterogeneity in developmental and intergenerational trajectories of childhood trauma may root from interindividual differences in the way trauma-exposed individuals have resolved these experiences. The current study explored whether distinctive patterns of impaired mentalization in relation to trauma could be identified in a sample of 825 pregnant women who experienced childhood maltreatment and whether these heterogeneous patterns were marked by significant differences in internalized and externalized problems during pregnancy, intimate partner violence, personality dysfunctions, and antenatal attachment. A latent profile analysis applied to the seven subscales of the Failure to Mentalize Trauma Questionnaire unraveled interindividual variability in mentalizing impairments among pregnant women exposed to childhood maltreatment by identifying five distinctive types of psychological responses to trauma, each being associated in cross-sectional analyses with a specific set of symptoms and dysfunctions. Overall, the study highlights the need for tailored interventions based on the individuals’ specific impairments in mentalizing trauma and calls for future developmental research exploring the longitudinal correlates of the five documented profiles of trauma processing.},

abstract = {Resolving trauma may contribute to mental health and parenting in mother with histories of childhood maltreatment. The concept of trauma-specific reflective functioning (T-RF) was developed to assess the complexity of thought processes regarding trauma. The study aimed to validate the T-RF scale applied to the Trauma Meaning-Making Interview by examining its psychometric properties, associations with measures of trauma-processing strategies, maternal reflective functioning and mental health (depression and post-traumatic stress disorder [PTSD]), as well as evaluating whether T-RF offered a unique contribution to maternal insightfulness. Good construct validity of the T-RF scale was confirmed in a sample of 112 mothers with histories of childhood maltreatment using an independent coding system of trauma-processing. Better mentalization of trauma was prospectively associated with higher parental reflective functioning and mothers with high T-RF were much more likely to be insightful regarding the child's mental states than non-reflective mothers and mothers with limited T-RF. The association between T-RF and insightfulness was observed even when controlling for maternal reflective functioning, trauma-processing strategies, maternal education and sociodemographic risk. T-RF was associated neither with depression, PTSD nor the characteristics of trauma. Findings suggest that mentalizing trauma would be an important protective factor in the intergenerational trajectories of trauma.},

abstract = {Introduction : Pendant leur grossesse, plusieurs femmes des Premières Nations doivent transiter en milieu urbain pour obtenir des soins périnataux. Les enjeux d’accessibilité et la présence de certains facteurs de risque (ex., diabète gestationnel) sont omniprésents. Or, la méfiance qu’elles entretiennent face aux soins de santé et aux services sociaux pourrait contribuer à accroître leur vulnérabilité lors de cette période.

Objectifs : Décrire l’expérience périnatale de femmes des Premières Nations, leur appréciation des soins périnataux reçus et la façon dont elles aimeraient être accompagnées par les professionnel·les de la santé.

Méthode : Une étude phénoménologique descriptive a été menée auprès de 10 femmes des Premières Nations transitant en milieu urbain. Des entretiens individuels ont été analysés selon la méthode de Giorgi (1997).

Résultats : Pour les participantes, la grossesse se révèle être une expérience positive et holistique, où toutes les dimensions de la santé sont influencées (physique, psychologique, émotionnel et spirituel). En ce qui a trait aux soins, le lien de confiance est primordial. Or, la majorité d’entre elles rapportent des expériences négatives lors des soins périnataux (ex., réactivation des traumas). Finalement, les participantes ont indiqué souhaiter obtenir plus d’information et bénéficier d’un accompagnement inclusif de leur culture lors de la période périnatale.

Discussion et conclusion : Pour les participantes, la maternité leur a donné l’occasion de prouver leur résilience. L’utilisation de leviers positifs favorise le mieux-être des femmes des Premières Nations. Il importe d’inclure les réalités et particularités culturelles de celles-ci dans les approches de soins dispensées par les professionnel·les de la santé lors de cette période de transition importante.},

This study investigated the potential spillover effect on pregnant women's perceptions of their relationships with their partners of the Supporting the Transition to and Engagement in Parenthood (STEP) program, a brief trauma-informed mentalization-based prenatal group intervention. Participants (94% White) were recruited in prenatal clinics and through online advertisements in Quebec, Canada. Both quantitative and qualitative data were collected from participants assigned to the STEP program (n = 42) and those receiving treatment-as-usual (TAU; n = 125). Women participating in STEP reported significant improvements in their relationships with their partners compared to those assigned to TAU. More precisely, they reported higher couple satisfaction, enhanced communication, and increased interest in their partners' emotional experience. The qualitative analysis further substantiated these results, with participants reporting having involved their partners in their pregnancy, shared their insights about themselves with their partners and gained fresh perspectives on their relationships. Participants in STEP also expressed sharing program materials with their partners and considered that such interventions should be extended to expecting fathers. This study underscores the potential of mentalization-based interventions to indirectly contribute to couple relationships, which may have positive implications for parenting and the infant.},

abstract = {OBJECTIVES: The extent to which heterogeneity in childhood risk trajectories may underlie later heterogeneity in schizophrenia (SZ), bipolar disorder (BP), and major depressive disorder (MDD) remains a chief question. Answers may optimally be found by studying the longitudinal trajectories of children born to an affected parent. We aimed to differentiate trajectories of global functioning and their sensitive periods from the age of 6 to 17 years in children at familial risk (FHRs).nnMETHODS: First, a latent class mixed model analysis (LCMM) was applied to yearly ratings of the Children's Global Assessment Scale (CGAS) from the age of 6 to 17 years in 170 FHRs born to a parent affected by DSM-IV SZ (N = 37), BP (N = 82) or MDD (N = 51). Then, we compared the obtained Classes or trajectories of FHRs in terms of sex, parental diagnosis, IQ, child clinical status, childhood trauma, polygenic risk score (PRS), and outcome in transition to illness.nnRESULTS: The LCMM on yearly CGAS trajectories identified a 4-class solution showing markedly different childhood and adolescence dynamic courses and temporal vulnerability windows marked by a functioning decline and a degree of specificity in parental diagnosis. Moreover, IQ, trauma exposure, PRS level, and timing of later transition to illness differentiated the trajectories. Almost half (46%) of the FHRs exhibited a good and stable global functioning trajectory.nnCONCLUSIONS: FHRs of major psychiatric disorders show heterogeneous functional decline during development associated with parental diagnosis, polygenic risk loading, and childhood trauma.},

A sample of 489 participants seeking help in private practice clinics completed self-report measures of sexual satisfaction, distress, and function, as well as dyadic adjustment, psychological distress, romantic attachment, personality impairment, and pathological personality facets. Results first showed that participants reaching the cutoffs for a personality disorder had significantly higher sexual distress and lower sexual function compared to participants without a personality disorder. Second, path analyses controlling for psychological distress, dyadic adjustment, and romantic attachment revealed that, for women, the Criterion B Intimacy Avoidance facet was consistently linked with higher sexual distress and lower sexual satisfaction and function. For men, result patterns were more complex, linking Criterion B Separation Insecurity with high sexual distress, and Separation Insecurity and Intimacy Avoidance facets with low sexual function. In addition, Criterion B Irresponsibility, Rigid Perfectionism, as well as Criterion A Intimacy impairment were linked with higher sexual satisfaction. These findings improve our understanding of the links between personality and sexual health and provide support for considering personality difficulties in sexual health interventions.},
