Interrater, intra-rater and internal consistency reliability of the Theory Application Assessment Instrument.
OBJECTIVE
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.


CONCLUSIONS
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.
