Reliability analysis was also carried out using item–total correlations to establish item homogeneity. The 6-item TOCS demonstrated adequate internal consistency with Cronbach’s a 1⁄4 :76.
Descriptive statistics
Table 3 contains the descriptive statistics for scores on the Type A behaviour scale, TASS, TOCS and the Perceived Stress Scale.
Considering the mean score for the Perceived Stress Scale, it indicates that on average participants reported moderate levels of perceived stress. The mean scores for both achievement striving and occupational commitment were quite high, and on average participants’ scores on the Type A personality were high enough to classify them as displaying Type A (as opposed to Type B) behaviour patterns. In fact, when classifying the teachers as either Type A or Type B (with scores of 84 and above indicating Type A individuals), 88.4% of the teachers displayed Type A behaviour patterns, and only 11.6% displayed Type B.
