IntroductionThe 8-item Stress Mindset Measure-General (SMM-G) is an instrument designed to assess stress-is-enhancing and stress-is-debilitating mindsets. The stress-is-enhancing stress mindset positively correlates with well-being indices and work productivity and negatively correlates with depression and anxiety scores. Mindset could be changed after a psychological, psychoeducational, or psychotherapeutic intervention.
MethodsA total of 564 Russian students (337 men, 229 women) from 9 universities aged 17 to 23 years (М=19,9) participated in the study. We computed reliability indicators, conducted exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).
ResultsPsychometric indicators are shown in Table 1. As a result of EFA (maximum likelihood, varimax rotation), two factors (eigenvalues 3,430 and 1,645) were extracted, accounting for 42,9% and 20,6% explained variance. Then, we tested the proposed model via CFA (Table 2).Table 1.Psychometric indicators
Mean value ± std | Cronbach`s alpha | Test-retest reliability (n=179, one month between assessments) |
---|
1,175±0,165 | 0,805 | 0,563 |
The first factor includes all odd-numbered questions, while the second factor contains all even-numbered questions. This is consistent with the questionnaire’s structure, leading to a natural interpretation of factors as the stress-is-enhancing and stress-is-debilitating mindsets.Table 2.CFA results
