Psychometric Properties of the Conners 3 ADHD (C3A)

Temperament, executive function, and attention-deficit/hyperactivity disorder (ADHD) in adolescents: The mediating role of effortful control

“…The DSM scales for inattention, hyperactivity-impulsivity and ADHD index were used. Gallant et al (2007) reported high internal consistency for two forms: Conners 3-P (content scales, .85 -.94; DSM symptom scales, .83 -.93), and Conners 3-T (content scales, .92 -.97; DSM symptom scales, .77 -.95). In our sample, reliability (Cronbach's alpha) was good: Conners 3-P (mean content scales, α = .84; mean DSM symptom scales, α = .82) and Conners 3-T (mean content scales, α = .88; mean DSM symptom scales, α = .82).…”

Impact of COVID‐19 on Children's Attention Deficit Hyperactivity Disorder Symptomology, Daily Life, and Problem Behavior During Virtual Learning

“…We used the long parent form, which is 110 items and takes parents about 20 min to complete. The parent scale has an internal consistency Cronbach's alpha of 0.91 and test–retest reliability 0.85 (Gallant, 2008 ; Gallant et al, 2007 ). Caregivers completed the validated SWAN (SWAN; Swanson et al, 2001 ) to determine ADHD diagnosis.…”

A comparative randomized controlled pragmatic trial of neurofeedback and working memory training for children with attention-deficit/hyperactivity disorder: protocol

“…In this study, the Swedish adaptation of the full-length Conners 3 consisting of 99Á115 items (depending on the informant) is used. The internal consistency of the Swedish version is good (a!0.82), and the testÁretest reliability is good to excellent for the parent (r tt 00.73Á0.95), teacher (r tt 00.73Á0.83), and self-rating (r tt 00.63Á0.81) version (45).…”
