The relationship between spirituality and behavioural addictions is complex. Although some studies have suggested spirituality to be a protective factor helping in recovery from addictive behaviours, others have found spirituality to be a potential risk factor. To better understand the relationship between spirituality and various behavioural addictions, this review summarises the literature on the association between spirituality and the following behavioural addictions: gaming disorder, gambling disorder, problematic internet use, problematic smartphone use, compulsive sexual behaviour disorder and compulsive buying/shopping disorder. Implications for clinical practice and future research are discussed.
