From self-regulation to character: digital well-being intervention effects on character strengths and subsequent distress

Character strengths (CS) are theorized to be a core mechanism of human flourishing, yet causal evidence for their malleability and role in mental health remains limited. In a randomized controlled trial of a 13-week digital well-being intervention among 2,315 healthcare professio...

Variance and local log-concavity of Poisson–binomial laws

Let W be the number of successes in independent trials with unequal success probabilities, with probability mass function f and variance V ≥ 1, and let D be the first index at which f decreases. The normalized Turán deficit δ_k = 1 − f_{k−1}f_{k+1}/f_k², a measure of local log-co...

The Psychometric Properties of General Mattering Scale, Anti-Mattering Scale, and Fear of Not Mattering Inventory and the Association With Loneliness Among Iranian Students

Mattering is an important psychosocial construct, yet evidence regarding the psychometric properties of mattering measures among Iranian university students remains limited. This study examined the psychometric properties of three mattering scales and their associations with lone...
