“…A more modest set of studies has addressed the mental health-spirituality relationship. Reviews generally indicate that religion tends to be slightly positively correlated with mental health (results vary by measurements used), a trend supported by increasingly sophisticated research designs ( Gartner, 1996 ;Hackney, 2010 ;Koenig, 2009 ;Koenig, McCullough, & Larson, 2001 ). Koenig et al for instance, found generally modest, positive correlations between religiousness and well-being in 80% of the reviewed studies, with religion positively correlated with greater hope and optimism, greater purpose and meaning, greater self-esteem, better adaptation to grieving, greater social support, less loneliness, less depression, fewer suicides, less anxiety, less schizophrenia, less drug and alcohol abuse, less delinquency and crime, and greater marital stability.…”
