Table 6 Evaluation of multidimensional instruments covering five or more systems
Selection criterion | T-ASI | Euro-ADAD | CAFAS | GAIN | POSIT | WAJCA-RA | ADI |
|---|---|---|---|---|---|---|---|
1) feasibility discrete choice experiment: # domains < 10 | 7 | 8 | 8 (+2 optional caregiver domains) | 8 | 10 | 12 | 12 |
2) practicability of assessment in clients: - # items < 500 - tta < 60 min. | 154 | 150 | 165 | 1606 | |||
30-45 | 45-55 | 10 | 60-120 | ||||
3) accessibility: price and availability of digital version | Digital version available free of charge | Digital version available free of charge | Available via paid online system (price $78-$400) | ||||
4) psychometric properties [validity (content validity, construct validity, sensitivity to change); reliability (test/retest reliability, internal consistency)] | Kaminer, 1991: “…interrater reliability is very good; indeed, it equals or surpasses that found for most interview instruments…” “Although further refinement needs to be made with respect to the Family Relationship ScaIe, the other individual scale ratings and the overall rating agreement is quite high, underscoring the reliability of the T-ASI.” (N=25) | Czobor, 2011: Good test-retest reliability (Pearson’s r >= 0.8 for most individual domains) and internal consistency (“Based on Cronbach’s coefficient alpha the internal consistency/reliability of the instrument was 0.50… when we applied an extension of the internal consistency/ reliability measure for multidimensional case, we found that the internal consistency/reliability was satisfactory.”); good criterion, convergent and discriminant construct validity. (N=632) | |||||
Kaminer, 1993: “…1) T-ASI discriminated between psychoactive substance use disorders (PSUD) and non-PSUD in adolescents within a group of psychiatric inpatients; 2) T-ASI substance use, psychiatric status, family function, and school status scores were related to external criteria; 3) there was specificity in these relations with external criteria…support for the valid psychometric properties of the T-ASI….All results should be interpreted in the context of the small sample size (N=25).” | |||||||
5) frequency of use in the field: - number of times used in studies | 4 | 1 |
