Spirituality seems to represent a relevant domain in the person-centred care planning and outcome assessment for persons with intellectual disability and low-functioning autism spectrum disorder. Despite this, the impact of spirituality on subjective well-being and quality of life (QoL) has been scarcely investigated. The aim of the present study was to map the international scientific literature in order to identify the reasons of such misconsideration and the key points for future research and practice implementation. The relationship between spirituality and QoL depends on a complexity of factors, ranging from QoL theoretical models to services' organisation. Personal attitude, family members, health and social-care personnel, training, faith and life communities, and even different religions seem to deserve an in-depth analysis.
