Despite this promising evidence, limited information is available on optimism and pessimism in headache disorders.

Objective: To evaluate the influence of optimism and pessimism in meeting criteria for migraine and related disability in a population-based sample.

Mechanisms Behind Religiosity and Spirituality's Effect on Mental Health, Quality of Life and Well-Being.

This cross-sectional study aims to evaluate the role of meaning, peace, faith and religiosity on mental health, quality of life (QOL) and well-being in 782 adults. We found associations between (a) meaning and peace with less depression and more QOL, (b) peace with less stress and (c) faith and religiousness with more psychological QOL. Meaning and peace were more strongly associated with health outcomes, and those with high levels of intrinsic religiosity but low levels of meaning/peace have worse outcomes than those with low religiousness and high meaning/peace.
