The present questionnaire study examined attachment-religion connections among 175 believers from Christian congregations within the Læstadianism revival movement in Sweden and Finland. Results generally supported the study’s hypotheses, thus partly replicated, and extended previous research. Replicating previous research, reports of secure attachment predicted the adoption and transmission of Christian beliefs and values. Reports of relative insecure attachment was linked to aspects of religious changes and predicted religious changes occurring in a life-context of emotional turmoil. Results for emotional compensation were, however, not consistent with previous research. Reports of secure attachment predicted emotionally-based religiosity and insecure attachment did not predict the intensity/suddenness of the religious change. Extending previous research, reports of secure attachment predicted the adoption and transmission of the congregation's Christian standards and perceived religious support from one's congregation. Findings are discussed in the context of the Læstadian population of the study.
