The current study conducted the first known bidirectional analysis of SIB and PEs to test whether SIB could be considered as a plausible antecedent for PEs. Prospective data were utilized from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative birth cohort of 2232 twins, that captured SIB (any self-harm or suicidal attempt) and PEs at ages 12 and 18 years. Cross-lagged panel models demonstrated that the association between SIB at age 12 and PEs at age 18 was as strong as the association between PEs at age 12 and SIB at age 18. Indeed, the best representation of the data was a model where these paths were constrained to be equal (OR = 2.48, 95% CI = 1.63 “3.79). Clinical interview case notes for those who reported both SIB and PEs at age 18, revealed that PEs were explicitly characterized by SIB/threat/death-related content for 39% of cases. These findings justify further investigation of the suicidal drive hypothesis.

Mapping early environment using communication deviance: A longitudinal study of maternal sensitivity toward 6-month-old children / Paulo DE SOUSA in Development and Psychopathology, 31-4 (October 2019)  

Public ISBD [article]  inDevelopment and Psychopathology > 31-4 (October 2019) . - p.1501-1511 Titre : Mapping early environment using communication deviance: A longitudinal study of maternal sensitivity toward 6-month-old children Type de document : texte imprimé Auteurs : Paulo DE SOUSA, Auteur ; William SELLWOOD, Auteur ; Kirsten FIEN, Auteur ; Helen SHARP, Auteur ; Andrew PICKLES, Auteur ; Jonathan HILL, Auteur ; Kate ABBOTT, Auteur ; L. FISHER, Auteur ; Richard P. BENTALL, Auteur Année de publication : 2019 Article en page(s) : p.1501-1511 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Communication deviance (CD) reflects features of the content or manner of a person's speech that may confuse the listener and inhibit the establishment of a shared focus of attention. The construct was developed in the context of the study of familial risks for psychosis based on hypotheses regarding its effects during childhood. It is not known whether parental CD is associated with nonverbal parental behaviors that may be important in early development. This study explored the association between CD in a cohort of mothers (n = 287) at 32 weeks gestation and maternal sensitivity with infants at 29 weeks in a standard play procedure. Maternal CD predicted lower overall maternal sensitivity (B = -.385; p < .001), and the effect was somewhat greater for sensitivity to infant distress (B = -.514; p < .001) than for sensitivity to nondistress (B = -.311; p < .01). After controlling for maternal age, IQ and depression, and for socioeconomic deprivation, the associations with overall sensitivity and sensitivity to distress remained significant. The findings provide new pointers to intergenerational transmission of vulnerability involving processes implicated in both verbal and nonverbal parental behaviors.
