2.  Provide information about desirable features of SWPBS evaluation tools  Provide an overview of the extent to which SWPBS evaluation tools meet these desirable features

3. PBS Self-Assessment Implement systems to support practices Implement practices Improved student outcomes EVALUATION DATA Use eval data for decision-making Fidelity measures Student outcome measures Action Plan Interpret eval data 1.Drive implementation decisions 2.Provide evidence for SWPBS impact on student outcomes

4.  A measure that drives implementation decisions should be: ◦ socially valid ◦ contextually appropriate ◦ sufficiently reliable (reliable enough to make defensible decisions) ◦ easy to use  A measure that builds the evidence base for SWPBS should: ◦ have known reliability ◦ have known validity ◦ clearly link implementation status to student outcomes

5.  Measurement scores have two components: ◦ True score, e.g. a school’s true performance on “teaching behavioral expectations” ◦ Error, e.g. features of the measurement process itself  Our goal is to use tools that 1.maximize true score and minimize measurement error, and therefore 2.yield precise and interpretable data, and therefore 3.lead to sound implementation decisions and defensible evidence. True score (relevant to construct) Error (noise)

6.  True score is maximized and error minimized if the evaluation tool is technically adequate, i.e. ◦ can be applied consistently (has good reliability) ◦ measures the construct of interest (has good validity)  Sound implementation decisions are made if the evaluation tool is practical, i.e. data ◦ are cost efficient to collect (low impact) ◦ are easy to aggregate across units of analysis (e.g. students, classrooms, schools, districts, states) ◦ are consistently used to make meaningful decisions (have high utility)

7.  Consistency across ◦ Items/subscales/total scales (“internal consistency”) ◦ Data collectors (“inter-rater reliability” or “inter-observer agreement”) ◦ Time (“test-retest reliability”)

8.  Definition: ◦ Extent to which the items on an instrument adequately and randomly sample a cohesive construct, e.g. “SWPBS implementation”  Assessment: ◦ If the instrument adequately and randomly samples one construct, and if it were divided into two equal parts, both parts should correlate strongly  Metric: ◦ coefficient alpha ( the average split-half correlation based on all possible divisions of an instrument into two parts)  Interpretation: ◦ α ≥.70 (adequate for measures under development) ◦ α ≥.80 (adequate for basic research) ◦ α ≥.90 (adequate for measures on which consequential decisions are based)

9.  Definition: ◦ Extent to which the instrument measures the same construct regardless of who collects the data  Assessment: ◦ If the same construct were observed by two data collectors, their ratings should be almost identical  Metric: ◦ Expressed as percentage of agreement between two data collectors  Interpretation: ◦ ≥ 90% good ◦ ≥ 80% acceptable ◦ < 80% problematic

10.  Definition: ◦ Extent to which the instrument yields consistent results at two points in time  Assessment: ◦ The measure is administered at two points in time. The time interval is set so that no improvement is expected to occur between first and second administration.  Metric: ◦ Expressed as correlation between pairs of scores from the same schools obtained at the two measurement administrations  Interpretation: ◦ r ≥.6 acceptable

11. How can we interpret this graph?

12.  Interpretability of data!  Did these schools truly differ in the extent to which they taught behavioral expectations?  Or…did these schools obtain different scores because ◦ the tool’s items captured only some schools’ approach to teaching expectations? (tool lacked internal consistency) ◦ they had different data collectors? (tool lacked inter-rater agreement) ◦ some collected data in week 1 and some in week 2 of the same month? (tool lacked test-retest reliability)

13.  Content validity  Criterion-related validity ◦ Concurrent validity ◦ Predictive validity  Construct validity

14.  Definition: ◦ Extent to which the items on an instrument relate to the construct of interest, e.g. “student behavior”  Assessment: ◦ Expert judgment if items measure content theoretically or empirically linked to the construct  Metric: ◦ Expressed as percentage of expert agreement  Interpretation: ◦ ≥ 80% agreement desirable

15.  Definition: ◦ Extent to which the instrument correlates with another instrument measuring a similar aspect of the construct of interest and administered concurrently or subsequently  Assessment: ◦ Concurrent validity: compare data from concurrently administered measures for agreement ◦ Predictive validity: compare data from subsequently administered measures for predictive accuracy  Metric: ◦ Expressed as a correlation between two measures  Interpretation: ◦ Moderate to high correlations are desirable ◦ Concurrent validity: Very high correlations might indicate redundancy of measures

16.  Definition: ◦ Extent to which the instrument measures what it is supposed to measure (e.g. the theorized construct “student behavior”)  Assessment: ◦ factor analyses yielding information about the instrument’s dimensions (e.g. aspects of “student behavior”) ◦ Correlations between constructs hypothesized to impact each other (e.g. “student behavior” and “student reading achievement”)  Metric: ◦ Statistical model fit indices (e.g. Chi-Square)  Interpretation: ◦ Statistical significance

17. How can we interpret this graph?

18.  Interpretability of data!  Can we truly conclude that student behavior is better in school F than school J? ◦ Does the tool truly measure well-defined behaviors? (content validity) ◦ Do student behaviors measured with this tool have any relevance for the school’s overall climate? For the student’s long-term success? (concurrent, predictive validity) ◦ Does the tool actually measure “student behavior”, or does it measure “teacher behavior”, “administrator behavior”, “parent behavior” ? (construct validity)

19.  Consider sample size ◦ Psychometric data derived from large samples are better than psychometric data derived from small samples.  Consider sample characteristics ◦ Psychometric data derived from specific samples (e.g. elementary schools) do not automatically generalize to all contexts (e.g. middle schools, high schools).

20.  Making implementation decisions based on evaluation data ◦ When has a school reached “full” implementation?  “Criterion” scores on implementation measures should be calibrated based on student outcomes Implementation student outcome goals criterion academic achievement 102030405060708090100 social achievement

21.  Evaluation data lead to consequential decisions, e.g. ◦ Additional trainings when data indicate insufficient implementation ◦ Emphasis on specific supports where data indicate greatest student needs  To make sure we arrive at defensible decisions, we need to collect evaluation data with tools that ◦ have documented reliability and validity ◦ clearly link implementation to student outcomes

22. 1. Collect evaluation data regularly 2. Collect evaluation data with tools that have good reliability and validity 3. Guide implementation decisions with evaluation data clearly linked to student outcomes
