TLDR
This study confirms the bi-dimensionality of the LOT-R and underpins that optimism and pessimism are two independent constructs rather than a single bipolar trait and can be employed to measure dispositional optimism or pessimism in individual diagnostics as well as in epidemiological research.Abstract:
Objectives. The relevance of the construct optimism in health psychology has been convincingly demonstrated in numerous studies. Population-based studies about dispositional optimism and the psychometric properties of the Life Orientation Test LOT-R as well as population-based norms are lacking.
Design. A representative population survey in Germany was conducted to investigate psychometric properties of the LOT-R and to deliver population-based norms.
Methods. A representative sample of 2,372 adults aged 18–93 years were screened using self-rating instruments.
Results. The confirmatory factor analysis (CFA) confirmed two factors. Optimism and pessimism are negatively correlated (r=−.20). Indications for convergent validity were demonstrated with depression, satisfaction with life, subjective state of health and health care utilization. Optimism is more strongly related to all indicators than pessimism. Since there are only marginal age and gender differences, norm data are given for the entire population.
Conclusions. Our study confirms the bi-dimensionality of the LOT-R and thus underpins that optimism and pessimism are two independent constructs rather than a single bipolar trait. Psychometric properties were found to be satisfactory. Together with the norm values reported in the paper, this instrument can, thus, be employed to measure dispositional optimism or pessimism in individual diagnostics as well as in epidemiological research.read more

TL;DR: The objective is to investigate prevalences, early onset markers, genetic predispositions, and the role of lifestyle factors of major civilization diseases, with primary focus on metabolic and vascular diseases, heart function, cognitive impairment, brain function, depression, sleep disorders and vigilance dysregulation, retinal and optic nerve degeneration, and allergies.

TL;DR: The present findings reinforce the view that psychedelics elicit psychosis-like symptoms acutely yet improve psychological wellbeing in the mid to long term, and are proposed that acute alterations in mood are secondary to a more fundamental modulation in the quality of cognition.
