Aim:
To investigate the interrater, intra-rater and internal consistency reliability of the Theory Application Assessment Instrument, a tool for testing competency in combining multiple theoretical conceptual practice models in client evaluation and treatment planning.
Methods:
The assessment was administered to 27 graduate students in two phases. The principal investigator rated the participants on the assessment scale on two separate occasions.
Results:
Interrater and intra-rater reliability were good for Phase 2 data. Internal consistency reliability for Phase 2 data was in the 'questionable' range.
Conclusion:
The instrument shows promise of being an efficient tool. However, this was an exploratory study with a small sample. Its replication with a larger more representative sample is needed to increase external validity.

Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...
