Diversity and representation in ADHD psychosocial treatment research: A comprehensive synthesis with data from over 10,000 participants.

Demographic data from nearly 50 years of treatment research for children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are synthesized. Comprehensive search identified ADHD treatment studies that were between-group designs, included a psychosocial, evidence-based treatment, and were conducted in the United States. One hundred and twenty-six studies that included 10,604 youth were examined. Reporting of demographics varied with 48% of studies (k = 61) reporting ethnicity, 73% (k = 92) reporting race, 80% (k = 101) reporting age (M age = 8.81, SD = 2.82), and 88% (k = 111) reporting gender. Most participants identified as non-Hispanic/Latine (15.99% Hispanic/Latine), White (62.54%), and boys (74.39%; 24.47% girls). Since the 1970s, zero youth in ADHD treatment studies identified as Middle Eastern/North African, 0.1% were American Indian/Alaskan Native or Native Hawaiian Pacific Islander, 1.77% were Asian, 15.10% were Black, and 3.14% were Multiracial. Based on publication year, the proportions of girls, racially minoritized youth, and Hispanic/Latine youth included in ADHD treatment research have increased over time. Girls, non-binary and non-cisgender youth, young children, adolescents, Hispanic/Latine youth, and youth from all racial groups other than White are underrepresented in ADHD treatment research. Research gaps are discussed, and recommendations for comprehensive demographic reporting in child and adolescent psychological research are provided.

Psychosocial Interventions for Attention-Deficit/Hyperactivity Disorder: Systematic Review with Evidence and Gap Maps.

OBJECTIVE: To inform the scope of future systematic reviews, meta-analyses, and treatment outcome studies, this review aims to describe the extent of the evidence for psychosocial interventions for children and adolescents with attention-deficit/hyperactivity disorder, with particular attention to specific types of interventions, targets of outcome assessment, and risk of bias. METHOD: A comprehensive search of relevant databases (i.e., Medline, PsychInfo, Education Resources Information Center, and ProQuest Dissertation Database) was conducted. Detailed information related to treatment type, outcome assessment, study design, and risk of bias was extracted by trained coders. Evidence and gap maps were created to summarize evidence within types of treatments and targets of outcome assessment. Indicators of risk of bias were assessed for selected combinations of treatments and outcome assessment. RESULTS: We identified 185 eligible individual studies and 3817 effect sizes. Behavioral parent training and cognitive training (COG) were the most commonly studied stand-alone interventions. Treatment versus control comparisons for stand-alone interventions (s = 70) were less common than for complex interventions involving combinations of psychosocial interventions (s = 100). Combinations of behavioral and child training (e.g., COG, organizational training) interventions were the most frequently studied. CONCLUSION: There is a considerable variability within this literature regarding combinations of treatments across outcome assessment targets. To address gaps in existing evidence, more primary studies assessing direct comparisons of isolated and combined treatment effects of specific types of psychosocial treatments relative to control and other treatments are needed. Future meta-analyses should take into account the complexity and breadth of available evidence.

Evaluating the Psychometric Properties of the Conners Adult ADHD Rating Scales.

Objective: Characterized by significant work-related impairments, difficulties with relationships, and higher rates of criminal behavior and substance abuse, ADHD is now understood as a disability that can persist throughout a lifetime. Differing opinions remain, however, regarding adult symptoms of ADHD, particularly with regard to gender differences. These issues add to the challenges of constructing a reliable and valid measure of ADHD for use with adults in research and practice. Method: We review the theoretical foundations of ADHD and psychometric properties of a major assessment device, the Conners' Adult ADHD Rating Scales (CAARS). Results: Results of the literature review found (a) a wide range of internal consistency estimates, with lowest values for the Diagnostic and Statistical Manual of Mental Disorders (DSM)-Hyperactive/Impulsive Symptoms subscale when completed by women, and (b) discriminant validity estimates in the same range as convergent validity estimates. Conclusion: These findings raise questions about the construct validity of the CAARS and suggest directions for future research.
