Early life maltreatment and depression: Mediating effect of maternal hair cortisol concentration on child abuse potential

Does childhood maltreatment influence Chinese preschool education college students' depression and anxiety? Evidence from a latent class analysis

Introduction

Preschool teachers' mental health may be a critical factor in their job performance, which in turn can influence the quality of early childhood education. However, little is known about its development. Childhood maltreatment, as a chronic form of childhood stress, may influence later mental health development. Although large, comprehensive research has been undertaken on childhood maltreatment and mental health, the associations between these two variables need further exploration. This study aims to describe childhood maltreatment based on person-centered approaches in Chinese preschool education college students, and to examine the differences in depression and anxiety within subgroups of childhood maltreatment.

Methods

A total of 1,218 Chinese preschool education college students participated in this study, and the data analysis was based on unconditional and conditional latent class analysis.

Results

The results showed that the participants were divided into 5 profiles: a non-maltreatment profile; a profile of emotional abuse and emotional and physical neglect; a profile of physical neglect; a profile of emotional neglect; and a profile of physical and emotional neglect. Students with multiple subtypes of maltreatment had the highest levels of depression and anxiety.

Discussion

Universities should consider both childhood maltreatment and profiles of childhood maltreatment when training preschool education college students.

Child maltreatment affects fathers’ response to infant crying, not mediated by cortisol or testosterone

Parents' ability to appropriately respond to infant crying is essential for parental care and has been found to relate to parents' own childhood experiences. Additionally, childhood experiences can affect endocrine factors, which may subsequently affect behavior. In the current study, preregistered on https://osf.io/hwgtu, we examined in expectant and new fathers (N = 152) associations between experiences of maltreatment in their own childhood, hair cortisol and testosterone concentrations and their ability to modulate handgrip force when exposed to infant crying. Cortisol and testosterone were quantified from the 1 cm of hair most proximal to the scalp using Liquid chromatography-tandem mass spectrometry. Participants were asked to squeeze a handgrip dynamometer at full and half strength while listening to infant cries and control sounds. Results indicated that fathers who experienced more childhood maltreatment used more excessive handgrip force during infant cry sounds. Hair cortisol and testosterone were not related to either experienced childhood maltreatment or handgrip strength modulation. These findings confirm that fathers’ early experiences of maltreatment reduce their ability to modulate their behavioral responses during infant cries, but suggest that hair cortisol and testosterone concentrations do not identify the underlying mechanism of this association.

•

Childhood maltreatment relates to fathers' behavioural responses to infant crying.

•

Childhood maltreatment is unrelated to fathers' hair cortisol and testosterone.

•

Cortisol and testosterone are unrelated to behavioural responses to infant cries.
