Toward a Dimensional Assessment of Externalizing Disorders in Children: Reliability and Validity of a Semi-Structured Parent Interview

Abstract

Objective: This study assesses the reliability and validity of the DSM-5-based, semi-structured Clinical Parent Interview for Externalizing Disorders in Children and Adolescents (ILF-EXTERNAL). Method: Participant data were drawn from the ongoing ESCAschool intervention study. The ILF-EXTERNAL was evaluated in a clinical sample of 474 children and adolescents (aged 6−12 years, 92 females) with symptoms of attention-deficit/hyperactivity disorder (ADHD). To obtain interrater reliability, the one-way random-effects, absolute agreement models of the intraclass correlation (ICC) for single ICC(1,1) and average measurements ICC(1,3) were computed between the interviewers and two independent raters for 45 randomly selected interviews involving ten interviewers. Overall agreement on DSM-5 diagnoses was assessed using Fleiss' kappa. Further analyses evaluated internal consistencies, item-total correlations as well as correlations between symptom severity and the degree of functional impairment. Additionally, parents completed the

Disentangling symptoms of externalizing disorders in children using multiple measures and informants.

“…The CD items evaluating aggressive and antisocial symptoms in participants aged 11 years or older were excluded from further analyses due to obvious floor effects. Psychometric evaluations support the interrater reliability, scale level: ICC(1,1) = .83–.95; ICC(1,3) = .94–.98, as well as the convergent and divergent validity of the ILF-EXTERNAL scale scores (Thöne et al, 2020). In the current sample, internal consistencies (Cronbach’s α: .60 ≤ α ≤ .87) and item-total correlations (.22 ≤ r it ≤ .68) were generally satisfactory to good (see ).…”

“…Each item is rated by the clinicians on a 4-point Likert scale ranging from 0 ( age-typical/not at all ) to 3 ( very much ), with higher scores reflecting greater symptom severity. Further details on the administration and scoring are reported in Thöne et al (2020). The ILF-EXTERNAL assesses IN symptoms (9 items) and HI symptoms (9 items) according to the DSM-5 to evaluate an ADHD diagnosis.…”

“…We analyzed baseline data (i.e., before any intervention) of 474 school-age children (age range 6-12 years, M = 8.9, SD = 1.5, 81% males). The screening to check the participants' eligibility for the multicenter study was based on the Clinical Parent Interview for Externalizing Disorders in Children and Adolescents (ILF-EXTERNAL; Görtz-Dorten et al, 2021) and is described elsewhere (Thöne et al, 2020). The baseline data set also included children who did not meet the criteria for an ADHD diagnosis (i.e., screening negatives of the ESCAschool study; n = 32, 72% males).…”

Establishing Occupational Therapy Needs: A Semi-Structured Interview with Hereditary Transthyretin Amyloidosis Patients

“…This represents essential information that should be taken into account for the development of OT programs. The first OT interviews and interventions should take place, even if the patients are in the early stages (I, II) of ATTRv, to maintain their independence as long as possible [ 23 , 24 , 25 ]. Early effective interventions are necessary to maximize the benefits of OT in these patients [ 16 ].…”

“…Therefore, this information could be extrapolated to ATTRv disease [ 16 ]. Our findings demonstrate the significant impact of ATTRv diagnosis on occupational performance as well as the need to develop appropriate OT educational programs aimed at multidisciplinary teams of healthcare professionals, occupational therapists, and ATTRv patients to ensure access to OT services and personalized interventions that may satisfy these patients’ specific occupational needs in a timely manner [ 23 , 24 , 25 , 26 ]. This result is consistent with the literature [ 23 , 24 , 25 , 26 ] after making a personal point of view.…”
