Dataset Information

Using latent class analysis to empirically classify maltreatment according to the developmental timing, duration, and co-occurrence of abuse types.

ABSTRACT:

Background

Individuals can have vastly different maltreatment experiences depending on the types, developmental timing, and duration of abuse. Women and men may be differentially affected by distinct abuse patterns.

Objective

To examine whether maltreatment subgroups could be identified based on the types, developmental timing, and duration of abuse, and to determine their prevalence among a large, community-based sample. We also examined sex differences in associations of maltreatment subgroups with adverse health outcomes.

Participants and setting

Data came from 9310 women and men (95 % White) in the United States who responded to the Growing Up Today Study questionnaire in 2007 (aged 19-27 years).

Methods

Participants reported on physical, sexual, and emotional abuse occurring in childhood (before age 11 years) and adolescence (ages 11-17 years). We conducted latent class (LC) analyses using indicators for child and adolescent abuse. We examined associations of LCs with health outcomes using sex-stratified log-binomial models with generalized estimated equations.

Results

We identified five LCs characterized by: 1) no/low abuse (59 %), 2) child physical abuse (16 %), 3) adolescent emotional abuse (9%), 4) child and adolescent physical and emotional abuse (16 %), and 5) child and adolescent sexual abuse (1%). LCs were uniquely associated adult health outcomes among both women and men. Associations of LCs with eating disorder behaviors appeared stronger for men than women.

Conclusions

Individuals experience distinct patterns of maltreatment based on the types, developmental timing, and duration of abuse. These patterns are uniquely associated with adverse health outcomes in adulthood, and can be identified using LCA.

Project description:PURPOSE:Adverse childhood experiences in sensitive periods of the developing brain render the individual at a life-long risk for a broad spectrum of aberrant health outcomes. However, there is a lack of scales for the comprehensive assessment of adverse childhood experiences providing information of various types and the age of occurrence. Based on the complete, experimental version of the Maltreatment and abuse chronology of exposure (MACE-X) scale, the present study aimed to develop and psychometrically test a Norwegian version of MACE. METHODS:The 75-item MACE-X was translated from German to Norwegian and administered as a self-report measure to 90 outpatients and 145 employees at a Division of specialized mental health care in South-Eastern Norway. The outpatients also completed the Childhood trauma questionnaire (CTQ) and the Symptom checklist 90 (SCL-90) to investigate convergent and predictive validity. To investigate test-retest reliability, outpatients completed MACE once more two weeks later. RESULTS:Rasch analysis and Anderson likelihood ratio tests on the combined outpatient and employee data resulted in a 55 item version of the Norwegian MACE. In the outpatient group, test-retest reliability of the MACE-55 was excellent for total scores (ICC ? 0.94) and good to excellent for 10 subscale scores (ICC ? 0.82). Convergent validity with the CTQ was moderate to high for both total scores (0.63 ? r ? 0.86) and subscale scores (0.56 ? r ? 0.82). As compared to CTQ total scores, a MACE total score that combined severity and duration of exposure was numerically more strongly associated with overall psychiatric symptoms and each of nine symptom domains on the SCL-90. CONCLUSIONS:The newly developed Norwegian MACE comprehensively assesses past exposure to adverse childhood experiences with high psychometric properties. This scale is a useful tool for research questions addressing sensitive periods for childhood adversities and associated health phenotypes.

Project description:There is increasing interest in childhood maltreatment as a potent stimulus that may alter trajectories of brain development, induce epigenetic modifications and enhance risk for medical and psychiatric disorders. Although a number of useful scales exist for retrospective assessment of abuse and neglect they have significant limitations. Moreover, they fail to provide detailed information on timing of exposure, which is critical for delineation of sensitive periods. The Maltreatment and Abuse Chronology of Exposure (MACE) scale was developed in a sample of 1051 participants using item response theory to gauge severity of exposure to ten types of maltreatment (emotional neglect, non-verbal emotional abuse, parental physical maltreatment, parental verbal abuse, peer emotional abuse, peer physical bullying, physical neglect, sexual abuse, witnessing interparental violence and witnessing violence to siblings) during each year of childhood. Items included in the subscales had acceptable psychometric properties based on infit and outfit mean square statistics, and each subscale passed Andersen's Likelihood ratio test. The MACE provides an overall severity score and multiplicity score (number of types of maltreatment experienced) with excellent test-retest reliability. Each type of maltreatment showed good reliability as did severity of exposure across each year of childhood. MACE Severity correlated 0.738 with Childhood Trauma Questionnaire (CTQ) score and MACE Multiplicity correlated 0.698 with the Adverse Childhood Experiences scale (ACE). However, MACE accounted for 2.00- and 2.07-fold more of the variance, on average, in psychiatric symptom ratings than CTQ or ACE, respectively, based on variance decomposition. Different types of maltreatment had distinct and often unique developmental patterns. The 52-item MACE, a simpler Maltreatment Abuse and Exposure Scale (MAES) that only assesses overall exposure and the original test instrument (MACE-X) with several additional items plus spreadsheets and R code for scoring are provided to facilitate use and to spur further development.
