The STAI is a two 40-item scale that assesses transient (state anxiety) and lasting levels of anxiety (state anxiety) [Spielberger et al., 1970; Spanish adaptation by Seisdedos (1982)]. For this study, only state anxiety was used to measure feelings of apprehension, tension, nervousness, and worry in the present moment. An example item was “I am tense; I am worried.” This test is answered based on a 1–4 scale to rate the intensity of the anxious feeling. Internal consistency coefficients for the scale have ranged from.86 to.95. In the present study, the state anxiety dimension showed excellent reliability (α = 0.91).
