Introduction to the Special Issue. A Dozen Years of Demonstrating That Informant Discrepancies are More Than Measurement Error: Toward Guidelines for Integrating Data from Multi-Informant Assessments of Youth Mental Health.

Validly characterizing youth mental health phenomena requires evidence-based approaches to assessment. An evidence-based assessment cannot rely on a "gold standard" instrument but rather, batteries of instruments. These batteries include multiple modalities of instrumentation (e.g., surveys, interviews, performance-based tasks, physiological readings, structured clinical observations). Among these instruments are those that require soliciting reports from multiple informants: People who provide psychometrically sound data about youth mental health (e.g., parents, teachers, youth themselves). The January 2011 issue of the Journal of Clinical Child and Adolescent Psychology (JCCAP) included a Special Section devoted to the most common outcome of multi-informant assessments of youth mental health, namely discrepancies across informants' reports (i.e., informant discrepancies). The 2011 JCCAP Special Section revolved around a critical question: Might informant discrepancies contain data relevant to understanding youth mental health (i.e., domain-relevant information)? This Special Issue is a "sequel" to the 2011 Special Section. Since 2011, an accumulating body of work indicates that informant discrepancies often contain domain-relevant information. Ultimately, we designed this Special Issue to lay the conceptual, methodological, and empirical foundations of guidelines for integrating multi-informant data when informant discrepancies contain domain-relevant information. In this introduction to the Special Issue, we briefly review the last 12 years of research and theory on informant discrepancies. This review highlights limitations inherent to the most commonly used strategies for integrating multi-informant data in youth mental health. We also describe contributions to the Special Issue, including articles about informant discrepancies that traverse multiple content areas (e.g., autism, implementation science, measurement validation, suicide).

Mother-Reported and Children's Perceived Social and Academic Competence in Clinic-Referred Youth: Unique Relations to Depression and/or Social Anxiety and the Role of Self-perceptions.

Depression and social anxiety symptoms and disorders are highly comorbid, and are associated with low social acceptance and academic competence. Theoretical models of both depression and social anxiety highlight the saliency of negative self-perceptions. We examined whether children's self-perceptions of social acceptance and mother-reported youth social acceptance are independently and uniquely related to children's depression and social anxiety, both before and after controlling for comorbid symptoms. Similar questions were examined regarding academic competence. The sample was 110 clinic-referred youth aged 8-16 years (65 boys, 45 girls; M age = 11.15, SD = 2.57). In the social acceptance area, both youth self-perceptions and mother-perceptions had independent and unique relations to depression and social anxiety, before and after controlling for comorbid symptoms. In the academic domain, both youth self-perceptions and mother-perceptions had independent and unique relations to depression, before and after controlling for social anxiety; yet only youth self-perceptions were related to social anxiety, before, but not after controlling for depression. For depression, larger effect sizes were observed for children's perceived, versus mother-reported, social acceptance and academic competence. Bootstrapping and Sobel tests found youth self-perceptions of social acceptance mediated the relation between mothers' perceptions and each of youth depression and social anxiety; and perceived academic competence mediated the relation between mothers' perceptions and youth depression, both before and after controlling for social anxiety. We found similarities and differences in findings for depression and social anxiety. Theoretical and treatment implications are highlighted, and future research directions are discussed.

Integrating etiological models of social anxiety and depression in youth: evidence for a cumulative interpersonal risk model.

Models of social anxiety and depression in youth have been developed separately, and they contain similar etiological influences. Given the high comorbidity of social anxiety and depression, we examine whether the posited etiological constructs are a correlate of, or a risk factor for, social anxiety and/or depression at the symptom level and the diagnostic level. We find core risk factors of temperament, genetics, and parent psychopathology (i.e., depression and anxiety) are neither necessary nor sufficient for the development of social anxiety and/or depression. Instead, aspects of children's relationships with parents and/or peers either mediates (i.e., explains) or moderates (i.e., interacts with) these core risks being related to social anxiety and/or depression. We then examine various parent- and peer-related constructs contained in the separate models of social anxiety and depression (i.e., parent-child attachment, parenting, social skill deficits, peer acceptance and rejection, peer victimization, friendships, and loneliness). Throughout our review, we report evidence for a Cumulative Interpersonal Risk model that incorporates both core risk factors and specific interpersonal risk factors. Most studies fail to consider comorbidity, thus little is known about the specificity of these various constructs to depression and/or social anxiety. However, we identify shared, differential, and cumulative risks, correlates, consequences, and protective factors. We then put forth demonstrated pathways for the development of depression, social anxiety, and their comorbidity. Implications for understanding comorbidity are highlighted throughout, as are theoretical and research directions for developing and refining models of social anxiety, depression, and their comorbidity. Prevention and treatment implications are also noted.

Girls' and mothers' social anxiety, social skills, and loneliness: associations after accounting for depressive symptoms.

This study examined, in 102 mother-daughter dyads, whether (a) girls' social skills and loneliness are related to girls' social anxiety, after adjusting for girls' depressive symptoms, and (b) mothers' social functioning (social anxiety, social skills, and loneliness) is related to girls' social anxiety, after accounting for girls' social functioning (social skills and loneliness) and mothers' and girls' depressive symptoms. After accounting for girls' depression, girls' loneliness (and not social skills) was related to girls' self-reported social anxiety and girls' social skills (and not loneliness) were related to mothers' reports of girls' social anxiety. Mothers' social functioning accounted for significant variance in girls' social anxiety, beyond that accounted for by girls' social functioning and mothers' and girls' depression. Mothers' loneliness and fear of negative evaluation showed significant relations to girls' social anxiety when variance attributable to other variables was partialed out, whereas mothers' social skills and social avoidance and distress did not. Directions for future research on social anxiety are highlighted.

Are discrepancies among child, mother, and father reports on children's behavior related to parents' psychological symptoms and aspects of parent-child relationships?

Examined whether parents' symptoms and qualitative and quantitative aspects of parent-child relationships make unique contributions to mothers' and fathers' reports of, and mother-child, father-child, and father-mother discrepancies on, children's behavior. Participants were 100 children, aged 10-12, and their mothers and fathers. Parents' symptoms and parent-child relationships made unique contributions to both parents' ratings of externalizing behavior. Although parent-child relationship variables were related to both parents' ratings of internalizing behavior, only parents' symptoms made unique contributions. On mother-child and father-child discrepancies, differences emerged between mother and father, and internalizing and externalizing behaviors. Both fathers' and mothers' symptoms contributed to father-mother discrepancies on both behavior types, with parent-child relationships contributing unique variance to discrepancies on internalizing behavior. Results highlight the importance of each informant's symptoms and relationship variables in understanding informant discrepancies.

Examining cognitive models of externalizing and internalizing problems in subgroups of juvenile delinquents.

Examined cognitive content and processes, from models of externalizing and internalizing problems, in incarcerated delinquents (N = 177). Four groups were defined by multiple criteria (with 41 youth not able to be classified): aggressive-internalizing (AI, n = 22); aggressive-noninternalizing (AN, n = 14); nonaggressive-internalizing (NI, n = 27); and nonaggressive-noninternalizing (NN, n = 73). Groups did not differ on self-centered and minimizing types of self-serving processing distortions, although the comorbid group endorsed more self-serving distortions of assuming the worst and blaming others than the NN group. Aggressive, in comparison to nonaggressive, delinquents reported more self-serving distortions in reference to overt behavior content. In contrast, self-debasing cognitive content was related to internalizing problems, as both the AI and NI groups had more negative beliefs about self than both the AN and NN groups, and more negative beliefs about the world and the future than the NN group. The AI group also had more negative beliefs about the world than the AN group. Self-debasing processing distortions were not specifically related to internalizing problems, as no differences emerged between the AN and NI groups; however, the AI group differed from the NN group on 3 of 4 types of these distortions. Both of the internalizing groups had a more negative attributional style than the NN group. Theoretical and treatment implications are highlighted.

A comparison of two self-report measures of children's social anxiety in clinic and community samples.

Examined the relations between the Social Phobia and Anxiety Inventory for Children (SPAI-C) and the Social Anxiety Scale for Children-Revised (SASC-R) in community (n = 178) and clinic (n = 57) samples. A large proportion of children exceeded the recommended SPAI-C and SASC-R cutoffs for suggesting clinically significant levels of social phobia and social anxiety in the community (37% SPAI-C and 20% SASC-R) and clinic (58% SPAI-C and 42% SASC-R) samples. A large proportion of children scoring in the clinical range on the Child Behavior Checklist (CBCL) exceeded the SASC-R and SPAI-C cutoff scores; however, there was notable variability with respect to sample, age group (< or = 10 years and > or = 11 years), sex, and measure (SPAI-C vs. SASC-R, and CBCL Internalizing vs. Social Competence scale). Using the recommended cutoffs, discriminant function analyses found the classification correspondence between the SPAI-C and SASC-R was significant, with some variability found in the 2 samples, age groups, and sexes (ranging from 82% to 91% classification correspondence). These initial findings highlight a need to consider sample, age, and sex in further examination of the utility and validity of these measures and their recommended cutoffs. Implications for future work examining the linkages between social anxiety and social phobia, as well as for the assessment of children's social anxiety and social fears, are discussed.
