The Perceived Stress Scale (PSS-10) is a 10-item questionnaire originally developed by Cohen et al. (1983) widely used to assess stress levels in young people and adults aged 12 and above. It evaluates the degree to which an individual has perceived life as unpredictable, uncontrollable and overloading over the previous month.


The questions ask about feelings and thoughts during the last month. In each case, respondents are asked how often they felt a certain way on a five-point scale from ‘never’ to ‘very often’. Answers are then scored as follow:

Never = 0

Almost never = 1

Sometimes = 2

Fairly often = 3

Very often = 4

To calculate a total PSS score, responses to the four positively stated items (items 4, 5, 7 and 8) first need to be reversed (i.e. 0 => 4; 1 => 3; 2 => 2; 3 => 1; 4 => 0).

The PSS score is then obtained by summing across all items. Higher scores indicate higher levels of perceived stress.

Normative data are available for adult populations for Bangladesh (Mozumder, 2019), Germany (Klein et al. 2016), Greece (Andreou et al. 2011), Mexico (González-Ramírez et al. 2013) and Sweden (Nordin, 2013).

The Perceived Stress Scale is not a diagnostic instrument and the developer has not published any score cut-offs.
