ABSTRACT Experts recommend that clinicians evaluating adults for attention-deficit/hyperactivity disorder (ADHD) obtain information from others who know the patient well. The authors examined correspondence between the self- and other-ratings of ADHD symptoms and impairment using 3 groups of adults recruited on the basis of their severity of ADHD: ADHD diagnosis (n = 146), clinical controls self-referring for ADHD but not diagnosed (n = 97), and community controls (n = 109). The influences of diagnostic group, informant relationship, sex of participant, IQ, and comorbid anxiety and depression on self-informant disparities were also examined. Results indicated moderate to high agreement (.59-.80) between self and others on current functioning and slightly lower levels (.53-.75) between self- and parent ratings of childhood functioning. Examination of difference scores between self- and other ratings revealed small mean disparities (-0.1 to +5.0 points) but substantial variation (SDs = -2.4 to 8.9 points) for both current and childhood ratings. Clinic referrals not diagnosed with ADHD, particularly women, had higher disparities than was evident in the ADHD and community groups. Age, IQ, and education were not associated with disparities in most ratings. Higher anxiety, in contrast, was associated with greater disparities on all current and childhood measures of both ADHD and impairment.

    ABSTRACT: Although extensive research suggests that attention-deficit/hyperactivity disorder (ADHD) and conduct problems (CP; symptoms of oppositional defiant disorder, conduct disorder, and antisocial personality disorder) contribute to risk for substance use, why these symptoms increase risk for substance use remains unclear. Given that research indicates that perceived peer tolerance and perceived peer substance use affect substance use, we evaluated the degree to which these peer-perception constructs mediated the association that ADHD symptoms, CP symptoms, and their interaction share with substance use (i.e., alcohol use, marijuana use, and illicit drug use). Participants were college students (N = 627; 60% female; 47% European American) with a mean age of 20.23 years. Results indicated that perceived peer use significantly mediated the association of ADHD symptoms with alcohol, marijuana, and illicit drug use, whereas perceived peer use only mediated the association between CP symptoms and alcohol use. Perceived peer tolerance significantly mediated the association that both CP and ADHD symptoms had with marijuana use, but not alcohol or illicit drug use. Finally, CP symptoms moderated the indirect effect that ADHD symptoms had on alcohol use through perceived peer tolerance. At low levels of CP symptoms, increases in ADHD symptoms corresponded to increases in perceived peer tolerance, which was related to increased alcohol use. However, at high levels of CP symptoms, increases in ADHD symptoms corresponded to decreases in perceived peer tolerance, which was associated with decreased alcohol use. Implications of findings are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

    ABSTRACT: Numerous studies have shown that attention deficit/hyperactivity disorder (ADHD) is associated higher risk of cannabis use disorders (CUD). However, these studies are limited in that most did not: (a) differentiate the role of hyperactivity-impulsivity (HI) and inattention (IN); (b) control for associated psychopathology; and (c) consider more fine-grained CUD-related measures. Our aim was to clarify the unique and interactive contributions of inattention and hyperactivity symptoms to age of cannabis initiation and DSM-IV cannabis dependence, craving, and severity of problems related to cannabis use while statistically controlling for symptoms of comorbid psychopathology in a non-clinical sample of young adults. Cannabis variables, current use of cigarettes and alcohol, current and childhood ADHD, and comorbid internalizing and externalizing psychopathology were assessed in 376 male and female undergraduates. Results indicate that current and childhood IN were independently associated with more severe cannabis use, craving, and problem use-related outcomes in young adulthood (p's<.01) and that childhood HI symptoms were associated with earlier initiation of cannabis (p<.01). Further, current IN symptoms moderated the relationships between level of use and more severe outcomes (p's<.01), such that higher IN strengthened positive associations among use and problem cannabis use. Associations with ADHD symptom dimensions and current use of alcohol and cigarettes were also present. Thus, current and childhood inattention symptoms as well as childhood hyperactive-impulsive symptoms emerged as significant factors in cannabis-related outcomes in young adults, even after statistically controlling for important confounding variables.

    ABSTRACT: Attention deficit/hyperactivity disorder (ADHD) is prevalent in homeless populations, but no studies have assessed the psychometric properties of assessment instruments for this population. Self-other agreement on the ADHD Self-Rating Scale 6 was studied using a cohort of admissions to an outreach clinic for the homeless (n = 72). Alcohol use was assessed with the fast alcohol screening test. Other drug use was assessed by interview. For the six-item ASRS-6, the self-nurse correlation was .63 (p < .001). Discriminant correlations were low. Higher ASRS-6 scores as rated by both nurse and self-report were associated with illicit drug use but not alcohol problems. Concordance was lower at higher levels of alcohol problems (p < .05) CONCLUSION:: The observations of experienced nurses converge well with self-reported symptoms of ADHD. Further research is needed to assess the relative contribution of clinical observation and self-report in assessing homeless patients.
