First record of the Neotropical cladoceran Diaphanosoma fluviatile in the Great Lakes basin.

The ctenopod Diaphanosoma fluviatile has been reported primarily from the Neotropical region and occasionally from the southern United States. D. fluviatile was collected in the Great Lakes basin (the Maumee River, Western Lake Erie, and Lake Michigan) in 2015 and 2018, far north from its previously known distribution. The occurrence of this southern species in the Maumee River and Great Lakes may be the result of an anthropogenic introduction, although a natural range expansion cannot be excluded. This report documents the northernmost record of D. fluviatile in the Nearctic region, extending the known distribution of the species to 42°N, which is a notable increase of 11 degrees latitude. Our detection of D. fluviatile is the first record of this southern species from the Laurentian Great Lakes drainage.

Therapists' and Clients' Perceptions of Bonding as Predictors of Outcome in Multisystemic Therapy®.

This longitudinal study examined whether strength of and balance in self-reported caregiver, youth, and therapist emotional bonds in mid- and late treatment predicted outcomes in Multisystemic Therapy of adolescent behavior problems in a sample of 164 caregiver-youth dyads. Strength of and balance in bonds related to outcome in different ways, depending on the source of the report and time. Results showed a limited association between family members' emotional connection with the therapist and treatment outcome, whereas therapists' perceptions of bond with the caregiver showed highly significant associations across time. Caregiver-therapist agreement on emotional connection at both time points predicted therapist evaluation of treatment success and successful termination, but this was largely explained by therapists' level of alliance. Balance in bonds with the therapist between caregiver and youth had no significant associations with any outcome. The study major limitations such as examining only one component of alliance and possible implications are discussed.

Adolescent Physiological and Behavioral Patterns of Emotion Dysregulation Predict Multisystemic Therapy Response.

This study examined whether physiological and behavioral indicators of emotion dysregulation assessed over the course of Multisystemic Therapy (MST) were related to treatment response. Participants were 180 ethnically diverse adolescents (n=120 males), ranging in age from 12 to 17 years. Treatment response was assessed through therapist report and official arrest records. Changes in cortisol reactivity and changes in scores on a behavioral dysregulation subscale of the Child Behavior Checklist were used as indicators of emotion dysregulation. Hierarchical linear modeling analyses examined whether a less favorable treatment response was associated with cortisol reactivity measures (a) collected early in treatment and (b) over the course of treatment, as well as with behavioral reports of emotion dysregulation reported (c) early in treatment, and (d) over the course of treatment. Sex was explored as a moderator of these associations. Results indicated that both cortisol and behavioral indices of emotion dysregulation early in treatment and over the course of therapy predicted treatment responsiveness. This relationship was moderated by sex: girls were more likely to evidence a pattern of increasing emotion regulation prior to successful therapy response. The results lend further support to the notion of incorporating emotion regulation techniques into treatment protocols for delinquent behavior.

Therapist perception of treatment outcome: Evaluating treatment outcomes among youth with antisocial behavior problems.

Effective evaluation of treatment requires the use of measurement tools producing reliable scores that can be used to make valid decisions about the outcomes of interest. Therapist-rated treatment outcome scores that are obtained within the context of empirically supported treatments (ESTs) could provide clinicians and researchers with data that are easily accessible and complimentary to existing instrumentation. We examined the psychometric properties of scores from the Therapist Perception of Treatment Outcome: Youth Antisocial Behavior (TPTO:YAB), an instrument developed to assess therapist judgments of treatment success among families participating in an EST, Multisystemic Therapy (MST), for youth with antisocial behavior problems. Data were drawn from a longitudinal study of MST. The initial 20-item TPTO:YAB was completed by therapists of 111 families at midtreatment and 163 families at treatment termination. Rasch model dimensionality analyses provided evidence for 2 dimensions reflecting youth- and caregiver-related aspects of treatment outcome, although a bifactor analyses suggested that these dimensions reflected a single more general construct. Rasch analyses were also used to assess item and rating scale characteristics and refine the number of items. These analyses suggested items performed similarly across time and that scores reflect treatment outcome in similar ways at mid and posttreatment. Multilevel and zero-order analyses provided evidence for the validity of TPTO:YAB scores. TPTO:YAB scores were moderately correlated with scores of youth and caregiver behaviors targeted in treatment, adding support to its use as a treatment outcome measurement instrument.

Social context, parental monitoring, and multisystemic therapy outcomes.

Multisystemic therapy (MST) and other evidence-based treatments targeting juvenile delinquency have been well substantiated in the literature. Although these treatments have been demonstrated to be effective overall at reducing juvenile delinquency, it is well known that they do not benefit all treated youth. Research has yet to examine the potential influence of contextual factors, such as socioeconomic status (SES) and neighborhood characteristics, on treatment outcomes, particularly as they influence parental monitoring, which is often a focus of interventions targeting juvenile delinquency. A primary goal of these treatments is to help parents develop the requisite skills to adequately monitor and discipline their children; however, this goal may be compromised by contextual factors affecting parental effectiveness and, ultimately, treatment efficacy. The objective of this study was to explore the role of SES and neighborhood factors in moderating the effects of parental monitoring across treatment. Using hierarchical linear modeling (HLM), we analyzed these contextual and family predictors of response to MST treatment within a sample of 185 youth (65.4% male) ages 12-18 (M = 15.35; SD = 1.28). Neighborhood factors interacted with parental monitoring, such that monitoring predicted decreases in externalizing behavior only for youth residing in better neighborhoods. In contrast, SES was unrelated to changes in externalizing behaviors in response to MST. Taken together, these results demonstrate a need for further understanding the potential role of the youth's larger social context in predicting MST outcomes.

Measuring impulsivity in adolescents with serious substance and conduct problems.

Adolescents with substance use and conduct disorders have high rates of aggression and attention deficit hyperactivity disorder (ADHD), all of which have been characterized in part by impulsivity. Developing measures that capture impulsivity behaviorally and correlate with self-reported impulsivity has been difficult. One promising behavioral measure, however, is a variant of the continuous performance test, the Immediate Memory Test/Delayed Memory Test (IMT/DMT). The authors showed significant group differences between adolescents in treatment for serious substance and conduct problems and community controls on impulsivity measures, both behavioral and self-report, as well as on aggression and problem behavior measures. Furthermore, the IMT/DMT correlated significantly with self-reported impulsivity. In summary, the IMT/DMT may be an effective behavioral measure of impulsivity in adolescents.

Discriminative validity and clinical utility of an abuse-neglect interview for adolescents with conduct and substance use problems.

OBJECTIVE: Many youths with conduct and substance use problems experience abuse and neglect. A valid measure of the severity of abuse-neglect events could facilitate research and clinical care. The authors' goal was to examine the discriminative validity, clinical utility, and severity correlations of the Colorado Adolescent Rearing Inventory, a structured, 20-45-minute abuse-neglect interview in the assessment of adolescents with conduct and substance use problems. METHOD: Ninety-eight adolescent patients with conduct and substance use problems and 102 comparison subjects (about 40% of the subjects in each group were female) completed the Colorado Adolescent Rearing Inventory, the Diagnostic Interview Schedule for Children, and the Composite International Diagnostic Interview-Substance Abuse Module. RESULTS: Although the subjects were advised that reports of abuse-neglect would be communicated to child welfare agencies, nearly two-thirds of the patients with conduct and substance use problems endorsed items indicating probable abuse-neglect, compared with about a third of the comparison subjects, a highly significant difference. Clinicians judged that 68%-80% of the cases of the patients and comparison subjects who endorsed such items warranted reporting to child welfare agencies. Scores on the Colorado Adolescent Rearing Inventory correlated significantly with severity of substance involvement, conduct disorder, and major depression. Compared to males, significantly more females (including 15% of comparison females) reported sexual abuse. Patients were significantly more likely than comparison subjects to attribute adverse life effects to their reported abuse-neglect experiences. CONCLUSIONS: Colorado Adolescent Rearing Inventory scores revealed many cases of serious abuse-neglect, generated many reports to child welfare agencies, demonstrated discriminative validity, correlated with clinical measures, and reflected important gender differences. The Colorado Adolescent Rearing Inventory can contribute to clinical evaluation and research involving youths with conduct and substance use problems.
