4.4.2 Acceptability of the Instrument
Acceptability or ease of use is determined by the number of participants who completed the questionnaire scale without omitting any items in addition to the required time to complete it (Kalisch et.al, 2010). 90.96% of the participants (N= 181) completed the instrument without omitting any items.

Also, they varied with team leadership. However, those who perceive autocratic team leadership style witnessed more frequently errors than other.
