  • How were items and content written?
  • How was the content checked?
  • How were the scales developed?
    • Rationally? By experts?
    • Statistically?

Administration and scoring

[edit | edit source]

General Administration Procedure

[edit | edit source]
  • Individual or group? Paper, computer, phone?
  • Typical time to administer (<--could look at metadata of completion times)
  • Age range
  • Any special notes for other respondents?
  • How to explain purpose to different respondents? (any pro tips for getting valid data?)
  • Readability

Computer Administration and Scoring

[edit | edit source]
  • Notes about any platforms (especially open ones), hardware and software requirements
  • REDCap?
  • QSF file?
  • Links to syntax or other materials
  • Pros and cons of computerization

Scoring Instructions

[edit | edit source]
  • What are the scales? What items go on which scale? Is the total meaningful?
  • Could include tables or figures
  • What to do with missing responses?
  • Are there profiles?
  • Percentiles or standard scores?
  • Cut scores or Diagnostic Likelihood Ratios?


[edit | edit source]
  • Scores
    • What items go on what scales?
    • Raw scores
    • Percent of max possible (POMP) scores?
    • Percentiles or standard scores?
    • Any IRT calibration or special weighting
  • If norms
    • Sex norms?
    • Age norms?
    • Informant norms?
  • Other demographic considerations
    • Evidence of differences across SES, social group, country?
  • Integrating information from multiple sources
  • Step-by-step sequence for interpretation

Normative Data

Description of the normative sample (if any) or the larger samples that have been published.

Ethnic differences?

Omega Group Factors (variance in total score due to 5 factors) .38 .22 .23
Observed Mean inter-item correlation .11 .15 .12

Projected correlation with full .72 .81 --
Observed correlation .92 .98 --
Reliability >.8 across range (IRT) -1.5 to 4.1 -3.3 to 5.0 -3.6 to 5.8
Discrepancy (Long – Short) .04ns .01ns --
SD discrepancy .xx .yy
95% limits of agreement .yy to .zz .yy to .zz
Savings in Length (%) 67% 33% 0%
Standard Error of Measurement .22 .17 .14
Standard Error of Difference .31 .24 .20
90% Critical Change .51 .39 .33
95% Critical Change .61 .47 .40
Minimal Important Difference (MID, d ~.5) .24 .24 .22

Note. Observed correlations are based on embedded item administration. Standard errors used OmegaTotal as reliability; ns = no significant difference between short and long form.


[edit | edit source]
  • Factorial validity
  • Convergent and divergent/discriminant validity
    • What things should correlate highly? Do they? (= convergent)
    • What about measures of other constructs? Do they show lower correlations? (= discriminant)
  • Discriminative validity - does it separate groups correctly? (= classification accuracy)
  • Other criterion validity
