Mental Health and Quality of Life Among Adults With Single, Multiple, and No Religious Affiliations.

Few studies have investigated the "multiple religious affiliations" phenomenon. This study aims to understand those with "multiple religious affiliations," describing its prevalence and investigating if there are differences in mental health and quality of life between this group and those with a single religious affiliation and those with no religious affiliation. A total of 1169 adults were included, and 58% had a single religious affiliation, 27.7% had multiple religious affiliations, and 12.3% had no religious affiliation. Participants with a single religious affiliation presented better mental health and quality of life than those with multiple or no religious affiliations. Although most outcomes were similar between multiple and no religious affiliations, happiness and optimism were higher in the multiple religious group, and anxiety was lower in the no religious group. Health care professionals should be aware of the secondary religious affiliations of their patients to identify possible conflicts and to treat them comprehensively.

Response Bias in Research on Religion, Spirituality and Mental Health: A Critical Review of the Literature and Methodological Recommendations.

Although a significant body of research supports the psychological benefits of religion and spirituality, more investigations are needed to understand the mechanisms by which they impact mental health. While some studies suggest a causal direct influence, the findings may still be subject to unmeasured factors and confounders. Despite compelling empirical support for the dangers of response bias, this has been a widely neglected topic in mental health research. The aim of this essay is to critically examine the literature addressing the role of response bias in the relationship between religion, spirituality and mental health. A survey of the diverse types of bias in this research area is presented, and methodological and theoretical issues are outlined. The validity and generalizability of the evidence are discussed, as well as the implications for mental health practice. A list of methodological remedies to reduce bias is suggested. The article is then concluded with a summary of the studies reviewed and directions for future research.

Final chapter, From India to the Planet Mars: A Study of a Case of Somnambulism with Glossolalia, by Théodore Flournoy (1900).

Among the many attempts to explain mediumship psychologically at the turn of the century were the efforts of Swiss psychologist Théodore Flournoy (1854-1920). In his well-known book Des Indes à la Planète Mars (1900), translated as From India to the Planet Mars (1900), Flournoy analysed the mediumistic productions of medium Hélène Smith (1861-1929), consisting of accounts of previous lives in France and in India, and material about planet Mars. Flournoy explained the phenomena as a function of cryptomnesia, suggestive influences, and subconscious creativity, analyses that influenced both psychology and psychical research. The purpose of this Classic Text is to reprint the conclusion of Flournoy's study, whose ideas were developed in the context of psychological attention to mediumship and secondary personalities.
