“…22 The average WFIRS-S Total score for a subset of adult students with ADHD was 0.88 and adult students without ADHD was 0.35. 27 The non-ADHD average score found in Canu et al’ s 27 study is similar with the average score of 0.31 found in the non-psychiatric public school sample of adolescents. 23 No research has been done to date, however, to determine the receiver operating characteristics (ROC) that would best distinguish clinical from non-clinical samples on the WFIRS-S.…”

“…Test–retest reliability found moderate to strong correlations between the ratings of WFIRS-S domains and Total score across varying time points. Canu et al 27 created a collateral report version of the WFIRS and found strong internal consistency and small to moderate cross-informant reliability between their student sample and collateral reporters. The WFIRS demonstrated higher levels of impairment in those with ADHD across two investigations.…”

ObjectiveThis is a narrative review of validation and outcome studies using the Weiss Functional Impairment Rating Scale (WFIRS). The objective of the review is to establish a framework for understanding functional impairment and create a definition for functional response and remission.MethodsWe conducted a literature search via MEDLINE, EBSCO and Google Scholar with no date restrictions and reviewed bibliographies of selected publications. Publications found in languages other than English were translated and clarification obtained from the author(s) if needed. Inclusion criteria were any manuscript that was either a WFIRS psychometric validation study or a clinical trial using the WFIRS as an outcome. There were no exclusion criteria.ResultsThe WFIRS has been validated in multiple cultures, and in clinical, research and control populations. The WFIRS has robust psychometric properties across ages, psychiatric status and informants. Outcome studies show variable improvement, with different response patterns between domains and among different interventions.ConclusionSymptom improvement and remission needs to be complemented with evaluation of functional improvement and remission to obtain a full picture of clinical status over the course of treatment.

College students with ADHD are at risk for a host of negative outcomes in academic, social, and emotional domains. However, the majority of college campuses do not provide comprehensive and individualized services to target the executive functioning difficulties and psychological comorbidity seen in college students with ADHD. The current manuscript describes the development of a specialized semester-long program to address the unique needs of college students with ADHD (Students Understanding College Choices: Encouraging and Executing Decisions for Success; SUCCEEDS) as well as the clinical, research, and training mission of this venture. Results from reliable change indices indicate that among the eight students in this case series, the majority reported significant improvements in organizational skills. Additionally, the majority of students with elevated rates of depression or alcohol use at baseline also reported significant improvement in these comorbid symptoms. A descriptive case study is also provided to further demonstrate the individualization and implementation of SUCCEEDS. Preliminary evidence suggests that SUCCEEDS is an effective method for addressing the personalized and wide-ranging difficulties experienced by college students with ADHD. Lessons learned and future directions for research are discussed.

“…Weiss Functional Impairment Rating Scale for parents and adolescents (WFIRS-P, WFIRS-S) 31 are questionnaires appropriate for parent report and adolescent and adult self-report of functional impairment typically affected in ADHD. The questions assess to what degree an individual's behavioural or emotional problems have affected various clinically relevant domains of functioning.…”

Cognitive–behavioural group therapy for adolescents with ADHD: study protocol for a randomised controlled trial

et al. 2020

View full text Add to dashboard Cite

IntroductionPersistence of attention deficit hyperactivity disorder (ADHD) into adolescence is a significant burden to patients. Clinical guidelines recommend non-pharmacological therapies, but the evidence to support this recommendation is sparse. This study aims to evaluate the effect of a 12-week group cognitive–behavioural therapy (CBT) programme for adolescents with ADHD aged 14–18 years, who still have impairing symptoms after treatment with medication. We will study the effect of the treatment on ADHD symptoms and examine moderators and mediators of the effect of the treatment on ADHD.Methods and analysisWe conduct a randomised controlled trial of CBT group therapy in adolescents with ADHD recruited from child psychiatric outpatient units in Mid-Norway. 99 adolescents who met inclusion criteria and consented to participation have been randomised to a 12-week group intervention or to a control group receiving treatment as usual. Assessments are made at admission to the clinic, preintervention, postintervention and at a 9-month follow-up, obtaining adolescent, parent and teacher reports. Clinicians blinded to group allocation rate all participants as to their functioning preintervention and at the two postintervention assessment points. The primary outcome is change in symptom scores on the ADHD Rating Scale-IV.Ethics and disseminationThe Regional Committee for Medical and Health Research Ethics in South East Norway approved the study protocol (2015/2115). We will disseminate the findings in peer-reviewed publications and conference presentations, to user organisations and at courses attended by families and professionals. Two PhD students will publish and defend dissertations relating to the study. Planned publications include primary and secondary outcomes and patient satisfaction with the treatment. Furthermore, we plan to publish a manual of CBT group therapy in adolescent ADHD to benefit treatment of patients in Norway and elsewhere.Trial registration numberNCT02937142

Psychometric Properties of the Weiss Functional Impairment Rating Scale: Evidence for Utility in Research, Assessment, and Treatment of ADHD in Emerging Adults

Abstract: The use of the WFIRS in identifying ADHD-related impairment in emerging adults appears to be psychometrically supported, and will prove useful to clinicians and researchers.
