Lifestyle is a complex and often generic concept that has been used and defined in different ways in scientific research. Currently, there is no single definition of lifestyle, and various fields of knowledge have developed theories and research variables that are also distant from each other. This paper is a narrative review of the literature and an analysis of the concept of lifestyle and its relationship to health. This contribution aims to shed light on the lifestyle construct in health psychology. In particular, the first part of this manuscript reexamines the main definitions of lifestyle in the psychological and sociological fields through three perspectives: internal, external, and temporal. The main components that characterise lifestyle are highlighted. The second part of this paper explores the main concepts of lifestyle in health, underlining their strengths and weaknesses, and proposes an alternative definition of a healthy lifestyle, which integrates the individual dimensions with the social and cycle dimensions of life. In conclusion, a brief indication of a research agenda is presented.

The incel community—which is characterized by an anti-feminist misogynistic ideology and has been linked with terrorist attacks—has become an increasing focus of attention among social scientists, policy makers, and professionals involved in preventing radicalization and extremism. In this systematic review we provide an up-to-date account of scientific research on the incel phenomenon. Using PRISMA guidelines, we initially identified 593 records, primarily through online database research. After full screening and duplicate removal, 78 articles remained. We divided the analyzed records into four macro-categorizations, covering theoretical, technological, violent, and personality-related components of the incel ideology. We examined the clinical implications of the analyzed findings, focusing on the potential criminological and pathological consequences related to the incel status—on a personal, interpersonal, and societal basis. Finally, suggestions regarding clinical intervention and future research foci are provided based on the knowledge gaps identified through the review.

The Verifiability Approach (VA) is a verbal veracity tool that assumes that truth tellers provide more details that can be verified and obtain a higher ratio of such details (verifiable details/total details) than liars. A VA meta-analysis was conducted. Results showed that truth tellers reported more verifiable details than liars (k = 20, N = 1532, g = 0.42). The effect was moderated by the presence of the information protocol and by the nature of the statement (event-related or not). Truth tellers reported a higher ratio of verifiable details than liars (k = 18, N = 1359, g = 0.49). The effect was moderated by the medium through which the statement was provided. Unverifiable details did not discriminate truth tellers from liars (k = 15, N = 957, g = −0.25). In conclusion, results showed good potential for the use the VA, although replications and field studies are needed.
