OBJECTIVE: To better understand early etiological pathways to trajectories of child exposure to community violence (CECV), we used person-centered latent class growth analysis (LCGA) to examine chronicity of CECV from early school age through early adolescence, and examined early risks of the identified CECV trajectories (i.e., prenatal cocaine exposure, harsh parenting and caregiving instability across infancy and early childhood, and child activity level and inhibitory control at kindergarten age). METHOD: An at-risk sample (N = 216; 110 girls) of primarily low-income participants (76% on Temporary Assistance for Needy Families) with high rates of prenatal substance exposure was used. The majority of the mothers were African American (72%), had high school or below education (70%), and were single (86%). Postnatal assessments occurred at eight time points during infancy and toddlerhood, early childhood through early school age, and early adolescence. RESULTS: We identified two distinct linearly increasing CECV trajectories (high-exposure and low-exposure). An interaction between child activity level and maternal harshness emerged, such that children with high activity levels and experiencing high harshness had the highest probabilities of being in the high exposure-increasing trajectory, in addition to early caregiving instability (conditional effect). CONCLUSION: The current findings not only have important theoretical implications but also provide insights into early intervention.

OBJECTIVE: Alexithymia is common among people who abuse alcohol, yet the mechanisms by which alexithymia exerts its influence remain unclear. This analysis tested a model whereby the three subscales of the Toronto Alexithymia Scale exert an indirect effect on alcohol problems through difficulties with emotion regulation and psychological distress. METHOD: Men and women (n=141) seeking alcohol use disorder (AUD) treatment completed the Toronto Alexithymia Scale, the Difficulties with Emotion Regulation Scale, the Brief Symptom Inventory, the Short Inventory of Problems, and the Alcohol Dependence Scale. RESULTS: The Difficulty Identifying Feelings subscale of the Toronto Alexithymia Scale was positively associated with alcohol problems through emotion dysregulation and psychological distress. The other two subscales, Difficulty Describing Feelings and Externally-oriented Thinking, were not associated with any other variables. CONCLUSION: People with alexithymia may consume alcohol to help regulate undifferentiated states of emotional arousal. Given the prevalence of alexithymia among people who abuse alcohol, treatment supplements that enhance the identification of emotions are needed.

Ovarian cancer is the second leading cause of death of female gynecological malignant tumor patients worldwide. Although surgery and chemotherapy have achieved dramatic achievement, the mortality remains high, resulting in the demand for new specific drug discovery. Disrupting ovarian cancer growth

The purpose of this study was to examine the moderating role of maternal sensitivity on the association between prenatal adversity and externalizing behaviors at 24 months of age in a diverse, high-risk sample. We hypothesized that among children with higher prenatal adversity, high maternal sensitivity would serve as a protective factor. Participants were 247 primarily low-income, diverse dyads. Results indicated a significant interaction effect of maternal sensitivity and prenatal adversity on externalizing problems. The association between prenatal adversity and externalizing behaviors was significant only among children who experienced low prenatal adversity, with higher maternal sensitivity associated with lower externalizing behaviors. These findings indicate that, in the absence of high prenatal risk, responsive and sensitive parenting can buffer children in an otherwise high-risk sample from the development of externalizing behaviors.El propósito de este estudio fue examinar el papel moderador que la sensibilidad materna tiene sobre la asociación entre adversidad prenatal y las conductas de externalización a los 24 meses de edad en un grupo muestra diverso y de alto riesgo. Nuestra hipótesis es que entre los niños con más alta adversidad prenatal (PA), una alta sensibilidad materna serviría como un factor de protección. Participaron 247 díadas diversas, primariamente de bajos recursos económicos (173 infantes expuestos a sustancias). Los resultados indicaron un significativo efecto de interacción de la sensibilidad materna y la adversidad prenatal sobre los problemas de externalización. La asociación entre la adversidad prenatal y las conductas de externalización fue significativa sólo entre niños que habían experimentado una adversidad prenatal baja, mientras que una más alta sensibilidad materna se asoció con más bajas conductas de externalización. Estos resultados indican que, en ausencia de un riesgo prenatal alto, una crianza receptiva y sensible puede amortiguar el desarrollo de conductas de externalización en niños que, de lo contrario, están dentro de un grupo muestra de alto riesgo.Le but de cette étude était d'examiner le rôle modérateur de la sensibilité maternelle sur l'association entre l'adversité prénatale et les comportements d'externalisation à l’âge de 24 mois chez un échantillon varié, et à haut risque. Nous avons pris comme hypothèse que chez les enfants avec une adversité prénatale élevée (PA), une sensibilité maternelle élevée servirait de facteur de protection. Les participants ont consisté en 247 dyades diverse et principalement issues de milieux défavorisés (173 bébés exposés à la toxicomanie). Les résultats indiquent un effet d'interaction important de la sensibilité maternelle et de l'adversité prénatale sur les problèmes d'externalisation. Le lien entre l'adversité prénatale et les comportements d'externalisation n’était important que chez les enfants ayant fait l'expérience d'une adversité prénatale peu élevée, avec une sensibilité maternelle plus élevée liée à des comportements d'externalisation moins élevés. Ces résultats indiquent que, en l'absence d'une risque prénatal élevé, le parentage réactif et sensible peut servir de tampon aux enfants contre le développement de comportements d'externalisation dans un échantillon qui est par ailleurs à haut risque.Die Auswirkung pränataler Belastung auf externalisierendes Verhalten im Alter von 24 Monaten in einer Stichprobe mit hohem Risiko: Mütterliche Sensibilität als Moderator Ziel dieser Studie war es, die moderierende Rolle mütterlicher Sensibilität im Zusammenhang zwischen pränataler Belastung und Externalisierungsverhalten im Alter von 24 Monaten in einer diversen Stichprobe mit hohem Risiko zu untersuchen. Die Hypothese bestand darin, dass bei Kindern mit höherer pränataler Belastung (prenatal adversity; PA) eine hohe Sensibilität der Mutter als Schutzfaktor dient. 247 hauptsächlich einkommensschwache, diverse Mutter-Kind Dyaden (173 davon substanzexponierte Säuglinge) nahmen an der Studie teil. Die Ergebnisse zeigten einen signifikanten Interaktionseffekt von mütterlicher Sensibilität und pränataler Belastung auf Externalisierungsprobleme. Der Zusammenhang zwischen pränataler Belastung und Externalisierungsverhalten war nur bei Kindern signifikant, bei denen eine geringe pränatale Belastung vorhanden war, wobei eine höhere Sensibilität der Mutter mit einem geringeren Externalisierungsverhalten assoziiert war. Diese Ergebnisse deuten darauf hin, dass, wenn kein hohes pränatales Risiko vorhanden ist, ein responsives und sensibles elterliches Verhalten Kinder in einer ansonsten risikoreichen Stichprobe vor der Entwicklung von Externalisierungsverhalten schützen kann.ハイリスク群の生後24ヶ月における外在化型の問題行動に対する出生前の困難な 課題の影響:緩和する役としての母親の感受性 本論文の目的は、多様でハイリスク群の出生前の困難な課題と生後24ヶ月における外在化型の問題行動の関連に対する母親の感受性の緩和する役割について調査することであった。我々は、より高い出生前の困難な課題(PA)のある子どもの中で、母親の高い感受性が予防要素として役立つのではないだろうかと仮定した。対象者は主に低収入で 多様な背景をもつ母子親子247組(173人の薬物曝露の新生児)である。結果は、外在化型の問題行動に対して母親の感受性と出生前の困難な課題との有意な相互作用の影響が示唆された。出生前の困難な課題と外在化型の問題行動の間の関連は、出生前の困難な課題を少なく体験した子どもの中で、外在化型の問題行動が低いことに関連した母親の感受性がより高いことのみ有意であった。これらの結果は、出生前の高いリスクがない場合において、応答的で感受性豊かな子育てが、それでもハイリスク群には入る子どもを外在化型の問題行動の発達から子どもを守ることができることを示唆している。.本研究的目的是在一个多样化的高风险样本中, 检验母亲敏感性在产前逆境与儿童24月龄时的外化行为之间的调节作用。我们假设处于更恶劣的产前逆境 (PA)中的儿童, 较高的母亲敏感性可以作为一个保护因素。研究参与者主要是247名低收入、多样化的母婴 (包含173名药物暴露的婴儿) 。结果表明, 母亲敏感性与产前逆境对儿童的外化问题有显著的相互作用。产前逆境与儿童外化行为之间的关联仅在经历过低程度的产前逆境的儿童中才有意义, 较高的母亲敏感性会导致较低的儿童外化行为。这些发现表明, 在没有经历高产前风险的情况下, 反应敏感的育儿可以缓冲儿童外化行为的发展, 否则他们会发展为高风险的样本。.تأثير الشدائد السابقة للولادة على السلوكيات السلبية في عمر 24 شهرًا في عينة عالية المخاطرة: حساسية الأمهات كعامل وسيط ملخص كان الغرض من هذه الدراسة هو دراسة الدور الوسيط للحساسية الأمومية في الارتباط بين الشدائد السابقة للولادة والسلوكيات السلبية في عمر 24 شهرًا في عينة متنوعة وعالية المخاطرة. افترضنا أنه بين الأطفال الذين يعانون من الشدائد ما قبل الولادة (PA) ، فإن الحساسية العالية للأمهات ستكون بمثابة عامل وقائي. وكان المشاركون 247 من الثنائيات المتنوعة ذات الدخل المنخفض (173 رضيع من المعرضين للمواد المخدرة). وأشارت النتائج إلى تأثير تفاعلي كبير لحساسية الأمهات والشدائد السابقة للولادة على مشاكل السلوكيات السلبية. كان الارتباط بين الشدائد السابقة للولادة والسلوكيات السلبية مهمًا فقط بين الأطفال الذين عانوا من الشدائد المنخفضة قبل الولادة ، بينما كان ارتفاع حساسية الأم مرتبطاَ بسلوكيات سلبية أقل. وتشير هذه النتائج إلى أنه في غياب مخاطر عالية قبل الولادة، يمكن الرعاية الوالدية المستجيبة والحساسة أن تشكل عامل وقائي للأطفال في عينة عالية الخطورة من تطور سلوكيات سلبية.

We examined a conceptual model for the associations of prenatal exposure to tobacco (PTE) and marijuana with child reactivity/regulation at 16 months of age. We hypothesized that PTE would be associated with autonomic reactivity and regulation that these associations would be indirect via maternal anger/hostility, depression/stress, or harsh parenting assessed at 2 months and that these effects would be most pronounced among children exposed to both tobacco and marijuana (PTME). Participants were 247 dyads (81 PTE, 97 PTME, and 69 nonexposed) who were followed up at 2 (N = 247) and 16 months (N = 238) of child age. Results from model testing indicated an indirect association between PTME and autonomic functioning during the second year of life, which was mediated by harsh parenting during caregiver-infant interactions. This study fills an important gap in the literature on PTE, PTME, and autonomic regulation during the toddler years, highlighting the role of maternal parenting as important intervening variables.

Researchers have suggested that heritable personality traits may predispose individuals to be willing to engage in the behavior. In particular, previous research has demonstrated a link between bullying perpetration and low levels of the HEXACO personality factor Honesty-Humility, which is a measure of an individual's willingness to exploit others. However, to date, evidence for the importance of low Honesty-Humility (versus low Agreeableness or Emotionality) has been drawn from North American or European samples. The present study attempts to address this gap by comparing data from 440 Chinese adolescents and 350 Canadian adolescents who completed the HEXACO-PR-I personality inventory along with a bullying questionnaire. We predicted that the personality factor Honesty-Humility would be a stronger predictor Chinese and Canadian adolescents' bullying perpetration than would anger (low A) or low empathy, emotional concern, and anxiety (low E). Results of hierarchical linear regressions confirmed that Honesty-Humility, as well as Conscientiousness, were significantly, negatively related to bullying perpetration in both samples. This suggests a cross-cultural profile of bullies as exploitative and impulsive, although Chinese bullies exhibited a more complex relationship with personality that included low Agreeableness and high eXtraversion. Implications of these results for the adaptive theory of bullying are discussed.
