Problem-Specific Racial/Ethnic Disparities in Pathways from Maltreatment Exposure to Specialty Mental Health Service Use for Youth in Child Welfare

The authors examined racial/ethnic differences in pathways from maltreatment exposure to specialty mental health service use for youth in contact with the Child Welfare system. Participants included 1600 non-Hispanic White, African American, and Latino youth (age 4–14) who were the subjects of investigations for alleged maltreatment and participated in the National Survey of Child and Adolescent Well-Being. Maltreatment exposure, internalizing, and externalizing problems were assessed at baseline and subsequent specialty mental health service use was assessed one year later. Maltreatment exposure predicted both internalizing and externalizing problems across all racial/ethnic groups, but non-Hispanic White youth were the only group for whom maltreatment exposure was linked with subsequent service use via both internalizing and externalizing problem severity. Only externalizing problems predicted subsequent service use for African American youth and this association was significantly stronger relative to non-Hispanic White youth. Neither problem type predicted service use for Latinos. It is likely that individual, family, and system-level factors converge to link African American youth with externalizing problems to services, but not as responsive in linking African American and Latino youth with internalizing problems to services...

For all racial/ethnic groups, we hypothesized that maltreatment exposure would be a strong predictor of both internalizing and externalizing problems, which was supported by our findings. We also expected that there would be a strong correlation between internalizing and externalizing problem severity in this high-risk population, which was also supported by our data. While our model considered the potential direct association between maltreatment exposure and MHS use, we predicted that maltreatment exposure would be indirectly linked to MHS via child emotional/behavior problems. Given the foregoing evidence suggesting racial/ethnic disparities in MHS use as a function of problem type for youth in contact with CW, we further hypothesized that these indirect pathways to care would differ for racial/ethnic minority youth, which also supported by our data. Specifically, although maltreatment exposure significantly predicted both internalizing and externalizing problem severity across all racial/ethnic groups, non-Hispanic White youth were the only group for whom both types of problems significantly predicted subsequent specialty MHS use. Only externalizing problems predicted subsequent specialty MHS use for African American youth and neither type of MH problem predicted service use for Latinos. Thus, we found evidence of disparities in pathways from maltreatment exposure to mental health service use that varied by problem-type and youth race/ethnicity. Furthermore, while externalizing problem severity was a predictor of specialty MHS use for both non-Hispanic White and African American youth, it was a much stronger predictor for African American compared to non-Hispanic White youth. Conversely, internalizing problem severity was a stronger predictor of specialty MHS use for non-Hispanic White youth compared to African American and Latino youth.

Taken together, these findings suggest a more complicated association between race/ethnicity and MHS use than what is suggested by research examining disparities without considering the type of MH problem in question. These differential patterns may be explained by individual, family, and system-level factors that lead to the particular visibility of racial/ethnic minority youth with disruptive behavior as compared to internalizing problems. However, the data and design of the current study does not enable us to discern whether these racial/ethnic disparities are due to differences in responsiveness on the part of the CW system in linking certain youth with certain needs to specialty MHS, or whether individual and family factors deter families from following through with MHS receipt.

It is likely that individual, family, and system-level factors converge to influence problem-specific disparities in pathways from maltreatment exposure to MH care for different racial/ethnic groups. Ethnic minority youth are overrepresented in CW and juvenile justice (; ), where externalizing problems are closely scrutinized. Disruptive behavior is also a robust predictor of placement instability in CW (), thus more resources may be directed towards youths with externalizing problems to support placement stability. CW workers may attend particularly to addressing the externalizing behaviors of African American youth who, in general, are at greater risk of placement instability and other negative CW outcomes. Data from NSCAW I suggest that externalizing problems are systematically associated with placement disruption for African American children but not for non-Hispanic White children (). Perhaps stronger linkages to effective care for disruptive behavior problems are all the more important for African American children who are more vulnerable to adverse system outcomes.

Yet, it may also be the case that individual and family factors work to amplify system-level determinants of MHS use. Even if a referral for MHS is made on the part of the CW system, racial/ethnic minority parents may hold culturally-influenced perceptions of child MH problems (e.g., beliefs about causes) and MHS (e.g., mistrust, stigma,) that may dissuade or encourage help-seeking (). These barriers may be more pronounced in the identification of and help-seeking for internalizing problems compared to externalizing problems in ethnic minority families (). While child behavior that is disruptive, oppositional, or defiant may run counter to cultural values that emphasize respect, obedience, and deference to adults, internalizing problems may not necessarily be at odds with such cultural values. The adult distress threshold model of cultural influence () suggests that culture may influence perceptions of how serious a problem is and decisions about what should be done. Because internalizing problems are already less likely to lead to MHS use, relative to externalizing problems (), the presence of internalizing problems in racial/ethnic minority children may not lead to sufficient distress to overcome a higher threshold for concern and the aforementioned barriers to accessing mental health services.

Examining specialty MHS use prospectively, use of a nationally representative sample of children in contact with the CW, and the application of analytic methods to examine moderation and indirect effects are notable strengths of this study. However, our results should be interpreted in light of study limitations. First, we relied on parent-report for all study variables and it would be important to replicate these results with multi-informant methods. Second, while the use of a general maltreatment latent variable is a strength in that it accounts for the complexity of exposure to such adversity, the current study does not examine potential differences related to specific forms of maltreatment. Third, although paths from internalizing and externalizing problems to MHS use were in the predicted direction, they were not statistically significant predictor of MHS use for Latino youth. Despite the large nationally representative sample, uneven group sizes could have impacted significance levels. For example, the relatively smaller sample of Latino youth and the resulting larger standard errors for estimates may have limited our ability to identify significant effects. Additional research examining specific determinants of MHS use for Latino youth in contact with child welfare is warranted. Fourth, we were unable to verify the Missing at Random (MAR) assumption from our missing data estimation used in Mplus. However, this concern is mitigated by the fact that there were few missing data. Fifth, we defined service use as any contact with an outpatient specialty MH provider and cannot comment on the effectiveness or quality of services. Furthermore, although we assessed child behavior problems, we are unable to specify the reasons families sought services. Lastly, while we examined overall racial/ethnic group disparities in specialty MHS use, we were unable to examine more proximal indicators of culture in our model due to limitations of the NSCAW data set. Research is needed to refine our understanding of enthnocultural factors impacting MHS use. Despite these limitations, these results highlight concerning patterns of disparities that require further study.

Gatekeepers of MHS, including those within the family and the broader CW system, may be more likely to direct attention to racial/ethnic minority youth with externalizing problems who are also at risk of having poor CW system outcomes. Yet, this greater responsiveness to disruptive behavior among African American children occurs in the context of disparities whereby racial/ethnic minorities are less likely to receive services overall. It stands to reason that racial/ethnic minority youth with clinical need that does not include disruptive behavior may be driving the overall pattern of disparities (). Increased awareness of these disparities as a function of problem type and increased awareness of the negative impact of untreated internalizing problems is needed within CW. While information provided to CW staff and families of children who come into the system may be one important avenue for targeting disparities, efforts must also focus on improving methods for identifying need and facilitating referral to MHS. Efforts to support the implementation of evidence-based MH assessment within CW and to examine the impact of these methods on disparities may help ensure equitable linkage of vulnerable youths to MHS.
