OBJECTIVE To compare educational, occupational, legal, emotional, substance use disorder, and sexual behavior outcomes in young adults with persistent and desistent attention-deficit/hyperactivity disorder (ADHD) symptoms and a local normative comparison group (LNCG) in the Multimodal Treatment Study of Children with ADHD (MTA). METHOD Data were collected(More)
Family history of mental illness provides important information when evaluating pediatric bipolar disorder (PBD). However, such information is often challenging to gather within clinical settings. This study investigates the feasibility and utility of gathering family history information using an inexpensive method practical for outpatient settings.(More)
Early, accurate identification of ADHD would improve outcomes while avoiding unnecessary medication exposure for non-ADHD youths, but is challenging, especially in primary care. The aim of this paper is to test the Strengths and Difficulties Questionnaire (SDQ) using a nationally representative sample to develop scoring weights for clinical use. The British(More)
BACKGROUND Compassionate support at the end of life should not be the responsibility of health and social care professionals alone and requires a response from the wider community. Volunteers, as community members, are a critical part of many end-of-life care services. The impact of their services on important outcomes such as quality of life is currently(More)
OBJECTIVE The purpose of this study was to examine similarities and differences between disruptive mood dysregulation disorder (DMDD) and bipolar disorder not otherwise specified (BP-NOS) in baseline sociodemographic and clinical characteristics and 36 month course of irritability in children 6-12.9 years of age. METHODS A total of 140 children with DMDD(More)
BACKGROUND Clinical care alone at the end of life is unlikely to meet all needs. Volunteers are a key resource, acceptable to patients, but there is no evidence on care outcomes. This study aimed to determine whether support from a social action volunteer service is better than usual care at improving quality of life for adults in the last year of life. (More)
Erratum Evangelia Papavasiliou worked on this protocol and the first few months of the project, but moved before the submission of the paper and was erroneously omitted in the original version of the paper [1]. The authors would like to acknowledge her work on the protocol and as a contributing author, and her details are therefore included in this erratum.(More)
BACKGROUND Despite the rapid growth in the sophistication of research on bipolar disorder (BD), the field faces challenges in improving quality of life (QoL) and symptom outcomes, adapting treatments for marginalized communities, and disseminating research insights into real-world practice. Community-based participatory research (CBPR)-research that is(More)
The objective of this study is to evaluate discriminative validity of the Young Mania Rating Scale (YMRS) and Children's Depression Rating Scale-Revised (CDRS-R) in a clinical sample of children when administered in an unfiltered manner (i.e., regardless of whether symptoms occur in a mood episode). The Kiddie Schedule for Affective Disorders and(More)
Expressed Emotion (EE; criticism/hostility and emotional overinvolvement) displayed in family interactions has been associated with the presence and poorer course of multiple disorders in adults and children. As such, validating appropriate tools for measuring EE could have important implications for research and clinical practice. Child EE measures are(More)
