%X BACKGROUND: Quantitative research on vigour as a therapeutically responsive marker of positive mental health, has become possible by virtue of the validation of the Vigour Assessment Scale (VAS). Considering that its validation and therapeutic responsiveness were examined in an avolitional schizophrenia population, using the VAS outside these constraints requires that its psychometric properties be investigated in a more general non-clinical population.
METHODS: Social media respondents (n = 787) were recruited on social media through snowball sampling and data were obtained for statistical analyses through an online questionnaire comprising the VAS and measures of work-place vigour, active involvement in personal growth, behavioural activation, procrastination, and fatigue.
RESULTS: Convergent validity was confirmed in moderate to strong positive correlations between the VAS and measures approximate to vigour including physical strength (r = 0.805), cognitive liveliness (r = 0.676), planfulness (r = 0.61), and intentional behaviour (r = 0.595). Discriminant validity was evident in negative correlations with procrastination (r = -0.593) and fatigue (r = -0.786). The VAS showed good internal consistency (Cronbach α = 0.951), split-half reliability (r = 0.892), test-retest reliability (r = 0.861), and a low standard error of measurement of 3.73 within a theoretical range of 82 points. Exploratory factor analysis yielded a clear two-factor structure.
CONCLUSIONS: Results are limited to willing participants who responded through social media.
CONCLUSIONS: Vigour may now be measured clinically as an indication of positive mental health and well-being. It may also be further investigated for its relations to other parameters of health, personality, and the efficacy of professional and self-enhancing interventions that aim for the cultivation of vigour.
