a. Appropriateness: the fit of the tool to the screening context, the purpose, and the need of
screening;
b. Technical adequacy: the validity, reliability, and accuracy of the screening tool;
c. Usefulness: the tool generates new and useful information supplemental to existing
information;
d. Feasibility: the ease of implementation and clarity of the referral pathway of the tool;
e. Beneficial properties: the cultural sensitivity and responsiveness and the absence of
harm of the tool.
There is no single tool appropriate for all children or screening situations. All the tools chosen
through expert consensus of the Panel are presently used in Iowa, typically in educational or
healthcare settings. The Panel cautions that the on-going process of suggesting screening
tools should include a rigorous evaluation of psychometric properties, usefulness, cultural
sensitivity, and supporting evidence of effectiveness.
The recommended tools are the best choices to ensure that tools used in Iowa are appropriate
to the child with regard to age, gender, ethnicity, cultural background, sexual orientation,
disability, or any other factor that would influence the developmental appropriateness of the
instrument being administered. The tools are research-informed and evidence-based to ensure
validity and reliability in identifying children and adolescents in need of further assessment.
The Panel recommends the following screening tools:
Modified Checklist for Autism (M-CHAT)
Survey of Wellbeing of Young Children (SWYC)
Patient Health Questionnaire (PHQ)
Ages and Stages Questionnaires (ASQ)
Strengths and Difficulties Questionnaire (SDQ)
Social Academic Emotional Behavior Risk Screener (SAEBERS)
CRAFFT (Car, Relax, Alone, Forget, Friends, Trouble)
Practice Parameters
Practice parameters are outlined by the Panel’s guidance on the following questions:
o When screenings will occur;
o Where screenings will be provided;
o Who will provide screenings; and;
o What will be included in the screenings.
The existing screening practices within Iowa provide a framework and sound rationale for
adopting the EPSDT-approved Bright Futures periodicity schedule (found in Appendix/Additional
Resources). This schedule has been married with the recommended schedule of screenings in
Iowa schools.
WHEN
The Panel recommends including key events in the periodicity schedule detailed here for
healthcare and education. These are the two places that encounter children most frequently
however the Panel encourages inclusion of all available settings (childcare and home visiting,
for example) in universal screening efforts. For both, there is an expectation of on-going
monitoring of development and the periodicity noted here is intended for the use of screening
tools.
