The aim of the present study was to study reliability and validity of Turkish version of the Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988) which is consisted of 20 items 10 of which is used to measure positive and other 10 to measure negative affect. Based on the data derived from 199 university students, 10 items loaded on both Positive and Negative Affect factors separately, as was anticipated. Besides studying factorial validity, internal consistencies were found as .83 and .86, respectively for positive and negative affect; and test-retest reliability coefficients were found as .40 and .54 sequentially. Criterion-related validity of Turkish version of this scale tvas studied through Beck Depression Inventory and Beck Anxiety Inventory scores. Results revealed that, Positive Affect presented correlations of -.48 and -.22 with these inventories respectively; while negative affect correlations were found to be .51 and .47 respectively for these inventories. Coherency of the findings with the literature was discussed.
