Some 1620 high school students responded to 68 items that measure adolescent stressors. Thirty-five of the items were based on J. P. Kohn and G. H. Frazer's Academic Stress Scale [1(1986) “An Academic Stress Scale: Identification and Rated Importance of Academic Stressors,”Psychological R...
ThePerceived Stress Scale(PSS) was applied to assess the stress level of athletes. This 10-item questionnaire measured global stress based on the subject's perception of stress in the past week. It was measured on a 7-point Likert-type scale from (0 for never to 6 very often. Internal c...
uncontrollable, and unpredictable, which were central components of the experience of stress (Averill,1973; Cohen,1978; Glass & Singer,1972; Lazarus,1966; Seligman,1975). The total PSS score indicates either a low, moderate, or high level of perceived stress. The higher the total score, the ...
An application of Raman spectroscopy on the measurement of residual stress in porous silicon The porous silicon film, at micron level, and the bulk silicon substrate is a basic structure in MEMS components. The residual stress, due to the lattice m... Y Kang,Q Yu,Z Lei,... - 《Optics ...
For this reason, it is important to have reliable methods for the measurement of these stresses and to understand the level of information they can provide. In this paper, which is the first part of a two part overview, the effect of residual stresses on fatigue lifetimes and structural ...
the exercise timed out. The allowed time differed per trial and was dependent on the difficulty level; participants had either 20 (for easy levels), 45 (for medium levels), or 100 s (for difficult levels) to respond. The difficulty level was validated in a pilot test to have it balanced...
Please note that the symptom severity used for these correlations is defined as the change from the individual symptoms baseline level at measurement time t0. a–c Correlation between LC responsivity (CI > II) and severity of anxiety symptom changes (STAI) (top) measured after 3 months ...
As we pointed out in the section “Stress drop and its mechanical significance,” stress drop is an important source parameter indicating the difference between the shear strength and the dynamic stress level. Although the absolute value of shear strength and the dynamic stress level cannot be cons...
’s (2019a) measure of the perceived support of the teaching and learning environment, was constructed from six items (see Table6) in which participants rated their level of agreement or disagreement with supportive behaviours of instructors. The ratings were then averaged to create a scale, ...
