Tool II and III were tested for their content validity and
reliability by Abd El- Hay (2008). The tools were tested for their
content validity by a jury of five experts in the psychiatric
Nursing and Medical field ascertained their validity and
relevance. The required modifications were carried out
accordingly. Then test-retest reliability was applied on the tools
and the questions that assess reaction of the studied patients
toward auditory hallucinations after a period two weeks, that the
patients were re-interviewed two weeks after their initial
interview to ascertain the reliability of the tools. Spearman's rank
correlation coefficient (Spearman's rho) was used to
measure the reliability of the tools. The tool II proved
to be strongly reliable ( r=0.972).Categories of tool (III)
proved to be strongly reliable, physiological strategy
(r=0.983), cognitive strategy (r= 0.997), and behavioral
strategy (r=1.000), proved to be completely reliable. And
lastly the question about reaction of the patient toward
auditory hallucinations (r=0.890).
