Strength Training and Quality of Life in Elderly

This questionnaire measures quality of live. It provides information on 8 scales, scoring from 0 (worst health) to 100 (best health), and on the physical component scale (PCS) and the mental component scale (MCS), normalized scores representing overall physical and mental functioning.

The State-Trait Anxiety Inventory (STAI) is a commonly used measure of trait and state anxiety (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983). It can be used in clinical settings to diagnose anxiety and to distinguish it from depressive syndromes. It also is often used in research as an indicator of caregiver distress. STAI has 20 items for assessing trait anxiety and 20 for state anxiety. All items are rated on a 4-point scale (e.g., from "Almost Never" to "Almost Always"). Higher scores indicate greater anxiety.

This questionnaire consists of 19 items measuring stages on the continuum of self-determination. It measures external regulation (4 items), introjected regulation (3 items), identified regulation (4 items), intrinsic regulation (4 items), and it adds amotivation (4 items) on a scale from 1 (Not at all true for me) to 5 (Absolutely true for me). Each of the subscales has a maximum score, with a maximum of 20 for external regulation, identified regulation, intrinsic regulation and amotivation, and 15 for introjected regulation.
