Latent Trait Effects Problematic Outcomes

If the source effects were greater than the trait effects for the summary score analyses, then it would be important to repeat the analyses separately for each situation. As noted earlier, if the mothers' and fathers' ratings are in agreement for the home situation and the teachers' and aides' ratings are in agreement for the school situation, then the separate analyses for each situation should result in an increase in trait variance and a decrease in the source variance for each measure. If the separate situation analyses both yielded stronger trait than source effects, then such results would support the consensual view within each situation. However, if the separate situation analyses still resulted in more source than trait variance, then the results would favor the bias view of the source effects.

Behavioral observations of ADHD-IN, ADHD-HI, and ODD symptoms in the home and classroom situations would help clarify the meaning of trait and source effects. Let us assume that the separate situation analyses yielded stronger trait than source effects for the ADHD-IN, ADHD-HI, and ODD measures. If the ADHD-IN, ADHD-HI, and ODD trait factors for the classroom analysis showed convergent and discriminant correlations with the ADHD-IN, ADHD-HI, and ODD observational measures, and the convergent correlations of each trait with its corresponding direct observation measure were larger than the correlations of the teacher and aide source correlations with the three direct observation dimensions, then such findings would indicate that the trait effects (systematic variance across the teacher and aide sources) reflect the "reality" of the behavior observations in a specific manner. If similar results occurred for the mother and father ratings, then our understanding of the mother, father, teacher, and aide ADHD-IN, ADHD-HI, and ODD measures would be greatly increased (e.g., stronger trait than source effects within each situation with the weaker trait effects across situations being due to the situational specificity of the children's behavior). Behavioral observations within each situation could thus help to understand the meaning of trait and source effects.

Understanding And Treating ADHD

Attention Deficit Disorder or ADD is a very complicated, and time and again misinterpreted, disorder. Its beginning is physiological, but it can have a multitude of consequences that come alongside with it. That apart, what is the differentiation between ADHD and ADD ADHD is the abbreviated form of Attention Deficit Hyperactive Disorder, its major indications being noticeable hyperactivity and impulsivity.
