Internet-based transdiagnostic treatment for emotional disorders in Arabic- and Farsi-speaking refugees: study protocol of a randomized controlled trial.

BACKGROUND: Refugee populations have an increased risk for mental disorders, such as depression, anxiety, and posttraumatic stress disorders. Comorbidity is common. At the same time, refugees face multiple barriers to accessing mental health treatment. Only a minority of them receive adequate help. The planned trial evaluates a low-threshold, transdiagnostic Internet-based treatment. The trial aims at establishing its efficacy and cost-effectiveness compared with no treatment. METHODS: N = 131 treatment-seeking Arabic- or Farsi-speaking patients, meeting diagnostic criteria for a depressive, anxiety, and/or posttraumatic stress disorder will be randomized to either the intervention or the waitlist control group. The intervention group receives an Internet-based treatment with weekly written guidance provided by Arabic- or Farsi-speaking professionals. The treatment is based on the Common Elements Treatment Approach (CETA), is tailored to the individual patient, and takes 6-16 weeks. The control group will wait for 3 months and then receive the Internet-based treatment. DISCUSSION: The planned trial will result in an estimate of the efficacy of a low-threshold and scalable treatment option for the most common mental disorders in refugees.

From Maltreatment to Psychiatric Disorders in Childhood and Adolescence: The Relevance of Emotional Maltreatment.

Different forms of maltreatment are thought to incur a cumulative and non-specific toll on mental health. However, few large-scale studies draw on psychiatric diagnoses manifesting in early childhood and adolescence to identify sequelae of differential maltreatment exposures, and emotional maltreatment, in particular. Fine-grained multi-source dimensional maltreatment assessments and validated age-appropriate clinical interviews were conducted in a sample of N = 778 3 to 16-year-olds. We aimed to (a) substantiate known patterns of clinical outcomes following maltreatment and (b) analyse relative effects of emotional maltreatment, abuse (physical and sexual), and neglect (physical, supervisory, and moral-legal/educational) using structural equation modeling. Besides confirming known relationships between maltreatment exposures and psychiatric disorders, emotional maltreatment exerted particularly strong effects on internalizing disorders in older youth and externalizing disorders in younger children, accounting for variance over and above abuse and neglect exposures. Our data highlight the toxicity of pathogenic relational experiences from early childhood onwards, urging researchers and practitioners alike to prioritize future work on emotional maltreatment.

Blended-ALMAMAR app for inpatient mental health care for refugees: study protocol for a multicenter implementation study within the I-REACH consortium (Internet based REfugee mentAl healtH Care).

BACKGROUND: Refugees are at high risk for developing mental illnesses. Due to language and cultural barriers, there is need for specifically adapted therapeutic procedures for refugees in inpatient mental health care settings. Internet-based applications in refugee mother tongues have the potential to improve the outcomes of mental health care for this vulnerable population. The key research question of the present implementation study is whether the newly developed "blended ALMAMAR" app for Arabic and Farsi speaking refugees in Germany is used and accepted by patients and professionals in routine inpatient mental health care (blended care). METHODS: We present the design of an observational, prospective multicenter implementation study in eight psychiatric hospitals. We plan to recruit 100 Farsi or Arabic speaking refugees receiving in-patient treatment due to depression, anxiety disorder, posttraumatic stress disorder or substance use disorders. These patients will get access to the "blended ALMAMAR" app during their inpatient stay in a blended-care approach. We will assess the usage (e.g., duration and frequency of use of the app) as well as subjective acceptability and usability of the intervention. To identify sociodemographic and clinical factors associated with "blended ALMAMAR" usage, we will also perform clinical and questionnaire assessments. DISCUSSION: The newly developed "blended ALMAMAR" app may help to close communication gaps for the hard-to reach and vulnerable group of refugees in inpatient mental health care. It is the first blended-care intervention that addresses severely mentally ill refugees in an inpatient psychiatric setting in Germany. TRIAL REGISTRATION: The trial was registered in the German Clinical Trials Register on November 11, 2021 (DRKS00025972) and adapted on November 14, 2023.

Pediatric Medical Traumatic Stress (PMTS) following Surgery in Childhood and Adolescence: a Systematic Review.

The purpose of the present review was to systematically review, synthesize and quantify prevalence rates of subclinical and clinical psychological symptoms in children and adolescents who have undergone surgery. Systematic literature searches were conducted twofold in April 8, 2020 and March 7, 2021 in PsycInfo and PubMed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Manuscripts were screened against eligibility criteria and were included if they investigated psychological symptoms in children or adolescents (age between 1 to 21 years at the time of study) who were hospitalized for pediatric surgery. Means and standard deviations weighted by sample size were calculated. Eleven articles met inclusion criteria. The review revealed that a small but substantial number of children and adolescents are at an elevated risk for postoperative psychological symptoms and disorders. Up to 13% had symptoms consistent with a diagnosis of a posttraumatic stress disorder, 6% to 8% exhibited elevated symptoms of depression or anxiety, and about 25% showed internalizing and externalizing symptoms. This review provides preliminary evidence that children and adolescents experience significant psychological distress and posttraumatic stress symptoms after pediatric surgery. Apart from better training of clinicians, prevention, early psychological screening and psychosocial care in surgical wards of hospitals are recommended. Well-designed studies of high methodological quality are necessary to replicate existing findings and provide a broader base of evidence.

Endocannabinoid concentrations in hair and mental health of unaccompanied refugee minors.

Altered activity of the endocannabinoid (EC) system has been linked to dysregulated stress-reactivity and the development of trauma-related psychopathology. The EC system, with its main components anandamide (AEA), 2-arachidonoyl-glycerol (2-AG) and other N-acyl-ethanolamides, is considered to be a buffer system that protects against the negative effects of traumatic experiences on mental health. Recently, the use of hair analyses, a method to gain information on long-term cumulative system activity, has been introduced to the study of ECs. Here, we seek to extend current knowledge on the potential use of hair EC concentrations as a marker of trauma-related psychological symptoms as well as psychological resources. Ninety-one male URM from Syria and Afghanistan (mean age = 17.4 years) living in group homes of the Child Protection Services in Leipzig, Germany, completed assessments on traumatic life events (TLE), PTSD symptoms, depression, anxiety and somatic symptoms as well as on self-efficacy and prosocial behavior. Scalp-near 3 cm hair segments were obtained and EC concentrations quantified using liquid chromatography tandem mass spectrometry. Analyses revealed relatively week and inconsistent associations of hair ECs and psychological symptoms, with only a positive correlation between 2-AG and depression. Concerning prosocial behavior and self-efficacy positive relationships were found with oleoylethanolamide (OEA), stearoylethanolamide (SEA), and palmitoylethanolamide (PEA). Our findings add data concerning the utility of hair EC analyses for PNE research but on a whole fail to reveal a clear association pattern between hair ECs and mental health in URM.

Childhood Emotional and Conduct Problems in Childhood and Adolescence Differentially Associated with Intergenerational Maltreatment Continuity and Parental Internalizing Symptoms.

Caregivers' own childhood maltreatment experiences potentiate the risk for psychopathology and perpetration of maltreatment against one's children. In turn, both of these factors may negatively impact children's mental health. The nature of these intergenerational patterns of maltreatment may vary as a function of type of child outcome and may also be influenced by child age and sample characteristics (i.e., involvement of Child Protection Services, CPS). The present study uses a Structural Equational Model to examine cross-sectional relationships between caregiver maltreatment experiences in childhood and child-rated emotional and conduct problems and tests the mediational effect of caregiver internalizing symptoms and child maltreatment exposure. This sample is comprised of 791 children aged 3-16 years (Mage = 10.6 years; n = 302 3 to 8-year-olds, n = 489 9 to 16-year-olds; 51.5% male) and their caregivers (88.4% biological mothers). Children were recruited from CPS (n = 124), youth psychiatric services (n = 144), and the general population (n = 523). Results indicated indirect links between caregivers' childhood maltreatment experiences and their children's emotional and conduct problems. Specifically, caregiver-perpetrated child maltreatment predicted was related to child conduct problems, whereas both caregiver-perpetrated child maltreatment and caregiver internalizing symptoms were related to child emotional problems. Multi-group analyses revealed no moderation effect of CPS involvement. Our results highlight the importance of independent outcome-specific intergenerational patterns in prevention approaches for families with maltreatment experiences.

Hair cortisol, lifetime traumatic experiences and psychopathology in unaccompanied refugee minors.

Attenuated cortisol secretion has been linked to traumatic experiences and the developmental psychopathology. Unaccompanied refugee minors (URM) form a highly vulnerable group in this context, usually exposed to multiple and severe traumatic experiences and characterized by a high, comorbid symptom-load. Here, we provide a first investigation in URM seeking to elucidate associations between long-term cortisol output, assessed through hair cortisol concentrations (HCC), lifetime traumatic events and psychological symptoms. Ninety-one male URM from Syria and Afghanistan (mean age = 17.4 years), living in group homes of the Child Protection Services in Leipzig, Germany, were examined. HCC were measured from scalp-near 3 cm hair segments and data on LTE, PTSD symptoms, depression, anxiety and somatic symptoms as well as emotional and conduct problems assessed. Results revealed HCC to be negatively related to lifetime traumatic events (total number, trauma types). In addition, a tentative finding of a positive association between HCC and emotional problems emerged. Results are discussed with regard to their relevance for HCC as a biomarker of the long-term endocrine consequences of chronic adversity and trauma exposure.

Getting less than their fair share: Maltreated youth are hyper-cooperative yet vulnerable to exploitation in a public goods game.

Human cooperative behavior has long been thought to decline under adversity. However, studies have primarily examined perceived patterns of cooperation, with little eye to actual cooperative behavior embedded within social interaction. Game-theoretical paradigms can help close this gap by unpacking subtle differences in how cooperation unfolds during initial encounters. This study is the first to use a child-appropriate, virtual, public goods game to study actual cooperative behavior in 329 participants aged 9-16 years with histories of maltreatment (n = 99) and no maltreatment (n = 230) while controlling for psychiatric symptoms. Unlike work on perceived patterns of cooperation, we found that maltreated participants actually contribute more resources to a public good during peer interaction than their nonmaltreated counterparts. This effect was robust when controlling for psychiatric symptoms and peer problems as well as demographic variables. We conclude that maltreatment may engender a hyper-cooperative strategy to minimize the odds of hostility and preserve positive interaction during initial encounters. This, however, comes at the cost of potential exploitation by others.

Alone, but protected? Effects of social support on mental health of unaccompanied refugee minors.

Unaccompanied refugee minors (URM) are the most vulnerable group of refugees suffering from higher levels of mental health problems. Yet, there is also a group of URM with little or no symptoms or disorders. A major predictor for positive mental health outcomes is the social support network in the post-flight period which has rarely been investigated for the group of URM. The present study analyzes differences between perceived social support from family, peers, and adult mentors in URM, with subgroup analyses of peer and mentor support in URM with and without family contact. Furthermore, we investigate whether social support from each of the three sectors moderates the relationship between stressful life events (SLE) and mental health of URM with family contact. Questionnaire data were collected from 105 male URM from Syria and Afghanistan aged 14-19 years who were living in group homes of the Child Protection Services in Leipzig, Germany, in summer 2017. URM receive most social support from their families, followed by peers and adult mentors. URM without family contact received less peer and mentor support compared to URM with family contact. Lower social support from mentors increased the risk for PTSD, depression and anxiety symptoms after SLE, whereas lower social support from peers increased the association between SLE and anxiety symptoms. Mentor and peer support in the host country is relevant for the processing of SLE. URM without family contact represent a "double burden" group, as they might feel less supported by other social networks.

[Mental Health Problems of Unaccompanied Young Refugees in Youth Welfare Institutions]. / Psychische Belastung bei unbegleiteten jungen Geflüchteten in Jugendhilfeeinrichtungen.

OBJECTIVE: Within the present study we investigated prevalence rates of psychological symptoms in underage and full-age unaccompanied refugees in youth welfare institutions. METHODS: Sociodemographic characteristics and mental health problems in the areas of emotion and behavior were assessed using screening data from both self-reports and caregiver reports of 105 youths. RESULTS: Symptoms of depression (42 %), behavior (35 %) and posttraumatic stress (32 %) were most frequently reported. There were no significant differences in frequencies of psychological symptoms between groups of underage and full-age unaccompanied refugees. Whereas youth reported more problems with peers, caregivers reported more psychological problems of youths in the areas of emotion, behavior, and hyperactivity. CONCLUSION: The data underline the need for psychological interventions of young unaccompanied refugees.

[Trauma First - an Outpatient, Cognitive-Behavioural Intervention for Children and Adolescents With Trauma-Related Disorders: a Pilot Study]. / "Trauma First" ­ ein ambulantes, kognitiv-behaviorales Behandlungsprogamm für Kinder und Jugendliche mit Traumafolgestörungen ­ Eine Pilotstudie.

Trauma First - an Outpatient, Cognitive-Behavioural Intervention for Children and Adolescents With Trauma-Related Disorders: a Pilot Study Abstract. Objective. Although traumatic experiences are one of the most important causes for psychiatric disorders in childhood and adulthood, trauma-specific intervention approaches are rarely applied in German outpatient clinics. The aim of the present pilot study was to evaluate a manualized, outpatient, cognitive-behavioural intervention programme ("Trauma First") for children and youths with trauma and stress-related disorders. We hypothesized that there would be specific improvements in PTSD symptoms as well as in depression, anxiety, and behavioural problems following the structured intervention programme. Method: The pilot study consisted of a pre-post-test design without a control group. Symptom severity of 33 children and youths (age: 10-15 years; 54.5 % female) with traumatic experiences was assessed by self-ratings and parent-ratings before and after the treatment. Results: After the treatment, improvements were found in children's PTSD symptoms, depression, anxiety, and behavioural problems (Cohen's d: 0.51-1.49). A trend was found showing improvement of children's life satisfaction. Effect sizes were comparable with results from meta-analyses. Conclusions: The pilot study provided first evidence for the effectiveness of "Trauma First" under ecologically valid conditions. This study is a first step in the evaluation process of psychotherapeutic effectiveness, which should be continued by conducting a randomized-controlled study design.

Latent trajectories of internalizing symptoms from preschool to school age: A multi-informant study in a high-risk sample.

Recent proposals suggest early adversity sets in motion particularly chronic and neurobiologically distinct trajectories of internalizing symptoms. However, few prospective studies in high-risk samples delineate distinct trajectories of internalizing symptoms from preschool age onward. We examined trajectories in a high-risk cohort, oversampled for internalizing symptoms, several preschool risk/maintenance factors, and school-age outcomes. Parents of 325 children completed the Strengths and Difficulties Questionnaire on up to four waves of data collection from preschool (3-5 years) to school age (8-9 years) and Preschool Age Psychiatric Assessment interviews at both ages. Multi-informant data were collected on risk factors and symptoms. Growth mixture modelling identified four trajectory classes of internalizing symptoms with stable low, rising low-to-moderate, stable moderate, and stable high symptoms. Children in the stable high symptom trajectory manifested clinically relevant internalizing symptoms, mainly diagnosed with anxiety disorders/depression at preschool and school age. Trajectories differed regarding loss/separation experience, maltreatment, maternal psychopathology, temperament, and stress-hormone regulation with loss/separation, temperament, maternal psychopathology, and stress-hormone regulation (trend) significantly contributing to explained variance. At school age, trajectories continued to differ on symptoms, disorders, and impairment. Our study is among the first to show that severe early adversity may trigger a chronic and neurobiologically distinct internalizing trajectory from preschool age onward.

Assessing psychological and physical abuse from children's perspective: Factor structure and psychometric properties of the picture-based, modularized child-report version of the Parent-Child Conflict Tactics Scale - Revised (CTSPC-R).

Child victims' reports of psychological and physical abuse by caregivers are a fundamental source of information beyond official records and caregiver reports. However, few or no sensitive and age-appropriate child-report instruments exist that have undergone in-depth validity and reliability testing across a broad age-range. Our study addresses this gap by examining psychometric properties of a picture-based, modularized version of the Parent-Child Conflict Tactics Scale (CTSPC-R), encompassing the maltreatment subtypes of psychological and physical abuse. A sample of 904 children and adolescents aged 4-16 years from the community (n = 568), child psychiatric services (n = 159), and from Child Protective Services (CPS; n = 177) completed the CTSPC-R. Measures to test convergent (maltreatment in parent interviews and CPS records) and concurrent validity (psychiatric symptoms) were collected. The CTSPC-R comprises 22 items, arranged in three severity modules by increasing level of psychological and physical abuse by caregivers. Companion picture cards were provided for children aged 4 and 8 years. The best fit to the data was attained with a second-order factor model, assuming three inter-correlated factors corresponding to the three severity modules, and a latent second-order factor representing combined physical and psychological abuse. The three factors showed good internal consistencies. Supporting convergent validity at the global and subtype-level of maltreatment, the CTSPC-R severity scale was associated with lifetime CPS-contact, presence of caregiver-reported emotional maltreatment and physical abuse, and dimensions of chronicity and severity. Discriminant validity was supported by non-significant correlations with caregiver-reported lack of supervision, failure to provide, and sexual abuse. Bolstering concurrent validity, moderate and severe physical abuse predicted caregiver-reported internalizing and externalizing symptoms. These effects were independent of child age, gender or community vs. non-community samples. Our study supports the CTSPC-R as a scientifically and clinically sound tool for ascertaining the child's own perspective on psychological and physical abuse from an early age onwards.

[Factors Influencing Theory of Mind Development in Preschoolers within the Context of Early Interventions]. / Einflussfaktoren auf die Theory of Mind-Entwicklung im Vorschulalter im Rahmen Früher Hilfen.

Factors Influencing Theory of Mind Development in Preschoolers within the Context of Early Interventions The Theory of Mind (ToM) competency is closely related to the child's cognitive, language, and socio-emotional development. In early interventions, skills and developmental processes associated with ToM development are often primary intervention targets, but empirical support for direct or indirect influences of early interventions on ToM development is missing so far. Within the home visiting program "Pro Kind" N = 755 families were accompanied by professionals from the last trimester of pregnancy until the child's second birthday. In the present follow-up study we investigated influences of treatment, pre- and postnatal family environment, parental competencies and child competencies on the ToM ability in a sample of n = 39 five-year-old children using Ctree analyses. Prenatal and current parental stress as well as an enriched family learning environment, and children's language competencies in interaction with temperament significantly predicted ToM competency. The treatment had no direct influence on ToM development. Thus, the results argue for the urgent need to address maternal stress regulation and mentalizing competencies in early interventions during pregnancy, as well as to focus on promoting positive stimulating learning environments and language development after the child's birth.

Follow-up study regarding the medium-term effectiveness of the home-visiting program "Pro Kind" at age 7 years: study protocol for a randomized controlled trial.

BACKGROUND: Pro Kind is a German adaptation of the US Nurse Family Partnership program. It is an intervention based on home visits targeting first-time mothers from disadvantaged populations. Pro Kind was implemented as a randomized control trial from 2006 to 2012 with N = 755 first-time mothers (TG n = 394, CG n = 391). The 7-8-year follow-up aims to assess the mid-term effects of the program. METHODS/DESIGN: Mid-term outcomes are being assessed by trained assessors. In a multimethod approach telephone interviews, on-site interviews, observations and developmental tests will be held in order to assess children's and mothers' life satisfaction, mental health, cognitive and social development, parenting behavior, signs of child abuse or neglect as well as the family's socio-economic status. Furthermore, administrative data will be accessed to obtain information regarding the mother's usage of pediatric health care, welfare usage and employment history. DISCUSSION: Results regarding the mid-term effects of the intervention from the Pro Kind Follow-up will provide a scientific basis for future primary prevention programs as well as help stakeholders legitimizing early childhood investments.

Like mother like daughter, like father like son? Intergenerational transmission of internalizing symptoms at early school age: a longitudinal study.

Despite the well-established link between parental depressive symptoms and children's internalizing symptoms, studies that divide transmission into gender-specific components remain scarce. Therefore, the present study focused on gender-specific associations between internalizing symptoms of parents and children over the course of early school age, a key stage where gender-specific roles are increasingly adopted. Participants were 272 children (49.6% girls) oversampled for internalizing symptoms. Parents completed questionnaires twice during early school age (mean age time 1 = 7.4 years; SD = 0.24; mean age time 2 = 8.5 years; SD = 0.28). Mothers and fathers separately reported on their own depressive symptoms and their child's internalizing symptoms. Latent multiple group analyses indicated gender-independent stability as well as gender-specific relations between parental and child outcomes. Maternal depressive symptoms were concurrently associated with symptoms of girls and boys, while paternal symptoms were concurrently associated only with symptoms of boys, but not of girls. Moreover, the associations between children and the parent of the same gender became more relevant over time, suggesting a growing identification with the same-gender model, particularly for fathers and boys. In regard to prospective effects, girls' internalizing symptoms at age 7 predicted paternal depressive symptoms 1 year later. In a rigorous longitudinal design, this study underscores the importance of gender specificity in the associations of internalizing symptoms between children and their mothers and fathers after controlling for symptom stability over time. The study also raises the interesting possibility that girls' internalizing symptoms elicit similar symptoms in their fathers.

Commentary: The importance of exploring dose-dependent, subtype-specific, and age-related effects of maltreatment on the HPA axis and the mediating link to psychopathology. A response to Fisher (2017).

We greatly appreciate Dr. Fisher's commentary that provides an excellent backdrop and well-considered perspective on our findings. We agree that our results mesh well with previous work documenting hypocortisolism among youth who experienced early adversity, especially neglect. Moreover, as also perceptively noted by Dr. Fisher, our cross-sectional data provide support for the notion that hypocortisolism is not simply a transient phenomenon, but, rather, a persistent pattern characterizing maltreated youth. Specifically, the consistency of the between group effect (from age 9.69 onwards) on a multimonth index of cumulative cortisol and the dose-dependent gradient of cortisol secretion within the maltreated group, which was related to the number of subtypes and the length of exposure to maltreatment, lend weight to this view.

Reduced hair cortisol after maltreatment mediates externalizing symptoms in middle childhood and adolescence.

BACKGROUND: The enduring impact of childhood maltreatment on biological systems and ensuing psychopathology remains incompletely understood. Long-term effects of stress may be reflected in cumulative cortisol secretion over several months, which is now quantifiable via hair cortisol concentrations (HCC). We conducted a first comprehensive investigation utilizing the potential of hair cortisol analysis in a large sample of maltreated and nonmaltreated children and adolescents. METHOD: Participants included 537 children and adolescents (3-16 years; 272 females) with maltreatment (n = 245) or without maltreatment histories (n = 292). Maltreated subjects were recruited from child protection services (CPS; n = 95), youth psychiatric services (n = 56), and the community (n = 94). Maltreatment was coded using the Maltreatment Classification System drawing on caregiver interviews and complemented with CPS records. Caregivers and teachers reported on child mental health. HCC were assessed in the first 3 cm hair segment. RESULTS: Analyses uniformly supported that maltreatment coincides with a gradual and dose-dependent reduction in HCC from 9 to 10 years onwards relative to nonmaltreated controls. This pattern emerged consistently from both group comparisons between maltreated and nonmaltreated subjects (27.6% HCC reduction in maltreated 9-16-year-olds) and dimensional analyses within maltreated subjects, with lower HCC related to greater maltreatment chronicity and number of subtypes. Moreover, both group comparisons and dimensional analyses within maltreated youth revealed that relative HCC reduction mediates the effect of maltreatment on externalizing symptoms. CONCLUSIONS: From middle childhood onwards, maltreatment coincides with a relative reduction in cortisol secretion, which, in turn, may predispose to externalizing symptoms.

The Pizzagame: A virtual public goods game to assess cooperative behavior in children and adolescents.

Social dilemmas are characterized by conflicts between immediate self-interest and long-term collective goals. Although such conflicts lie at the heart of various challenging social interactions, we know little about how cooperation in these situations develops. To extend work on social dilemmas to child and adolescent samples, we developed an age-appropriate computer task (the Pizzagame) with the structural features of a public goods game (PGG). We administered the Pizzagame to a sample of 191 children 9 to 16 years of age. Subjects were led to believe they were playing the game over the Internet with three sets of two same-aged, same-sex co-players. In fact, the co-players were computer-generated and programmed to expose children to three consecutive conditions: (1) a cooperative strategy, (2) a selfish strategy, and (3) divergent cooperative-selfish strategies. Supporting the validity of the Pizzagame, our results revealed that children and adolescents displayed conditional cooperation, such that their contributions rose with the increasing cooperativeness of their co-players. Age and gender did not influence children and adolescents' cooperative behavior within each condition. However, older children adapted their behavior more flexibly between conditions to parallel the strategies of their co-players. These results support the utility of the Pizzagame as a feasible, reliable, and valid instrument for assessing and quantifying child and adolescent cooperative behavior. Moreover, these findings extend previous work showing that age influences cooperative behavior in the PGG.

A Multisource Approach to Assessing Child Maltreatment From Records, Caregivers, and Children.

Practitioners and researchers alike face the challenge that different sources report inconsistent information regarding child maltreatment. The present study capitalizes on concordance and discordance between different sources and probes applicability of a multisource approach to data from three perspectives on maltreatment-Child Protection Services (CPS) records, caregivers, and children. The sample comprised 686 participants in early childhood (3- to 8-year-olds; n = 275) or late childhood/adolescence (9- to 16-year-olds; n = 411), 161 from two CPS sites and 525 from the community oversampled for psychosocial risk. We established three components within a factor-analytic approach: the shared variance between sources on presence of maltreatment (convergence), nonshared variance resulting from the child's own perspective, and the caregiver versus CPS perspective. The shared variance between sources was the strongest predictor of caregiver- and self-reported child symptoms. Child perspective and caregiver versus CPS perspective mainly added predictive strength of symptoms in late childhood/adolescence over and above convergence in the case of emotional maltreatment, lack of supervision, and physical abuse. By contrast, convergence almost fully accounted for child symptoms for failure to provide. Our results suggest consistent information from different sources reporting on maltreatment is, on average, the best indicator of child risk.
