Pedometer (PFA) vs Perceived Stress Scale
Side-by-side comparison of two open source alternatives
Pedometer (PFA)
Privacy Friendly Pedometer can count your steps in background, provides you an overview about your walked steps and allows you to define custom walking modes and notifications if the achievement of your daily step goal is in danger. The app requires minimal permissions (Run at startup and prevent phone from sleeping). It belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Intitute of Technology. More information can be found an secuso.org/pfa Privacy Friendly Pedometer can count your daily walked steps while it runs in background. It gives you an overview about your walked steps, distance and about the calories you have burned while walking. You can add and choose different walking modes with different step lengths, such as walking or running, to improve the calculation of distance and calories. In a special training mode you can track your training sessions. To each training session additional information, such as feeling or a description, can be added. What makes Privacy Friendly Pedometer different from other pedometers? 1. Minimal amount of permissions: * Run at startup: This permission is required to restart the step counting when your phone boots. * prevent phone from sleeping: On some devices the processor falls asleep and prevents counting steps. With this permission the app can keep the processor awake while counting steps. Most of Pedometer Apps in the Google Play Store require additional permissions. E.g. accessing the network or Internet which is mostly used to display advertisement. Some apps have access to GPS or telephony data. 2. No advertisement. Many other free apps in the Google Play Store dazzle annoying advertising and also shortens battery life.

Perceived Stress Scale
The Perceived Stress Scale (PSS) is the most widely used psychological instrument for measuring the perception of stress. It is a measure of the degree to which situations in one's life are appraised as stressful. Items were designed to tap how unpredictable, uncontrollable, and overloaded respondents find their lives. The scale also includes a number of direct queries about current levels of experienced stress. The PSS was designed for use in community samples with at least a junior high school education. The items are easy to understand, and the response alternatives are simple to grasp. Moreover, the questions are of a general nature and hence are relatively free of content specific to any subpopulation group. The questions in the PSS ask about feelings and thoughts during the last month. Evidence for Validity: Higher PSS scores were associated with (for example): - failure to quit smoking - failure among diabetics to control blood sugar levels - greater vulnerability to stressful life-event-elicited depressive symptoms - more colds Because levels of appraised stress should be influenced by daily hassles, major events, and changes in coping resources, predictive validity of the PSS is expected to fall off rapidly after four to eight weeks.
