The Perceived Stress Scale was originally suggested as a 14-item scale (PSS-14, Cohen et al, 1983) and later shortened to 10 items (Cohen & Williamson, 1988). "Items in the PSS-10 were designed to tap how unpredictable, uncontrollable, and overloading respondents find their lives" (Cohen & Janicki-Deverts, 2012, p. 1323) References: Cohen, S., Kamarck, T., & Mermelstein, R.
