Military spouses are often left at home when their service member deploys to areas outside the United States. These deployments can have a lasting impact on the military spouses' perception of marital happiness. Communication problems can occur within the marriage and military spouses may use their religious orientation to alleviate the stress that comes from deployments. This quantitative study used an online survey method to conduct bivariate correlations and multiple regression analysis from a sample of 128 military spouses. This study focused on the family stress theory and used the Kansas Marital Satisfaction Scale, Extrinsic and Intrinsic Religious Orientation Scale, and Primary Communication Inventory. Bivariate correlations indicated a significant relationship between communication, extrinsic religious orientation, intrinsic religious orientation, and marital happiness. Multiple regression indicated a strong significant relationship with communication and a negative significant relationship with extrinsic and intrinsic religious orientation. After controlling for the covariates, communication and age of spouse were significant, while the remaining variables were nonsignificant. In addition, binary logistic regression was conducted, and communication and intrinsic religious orientation were significant, while extrinsic religious orientation was nonsignificant with marital happiness. The experiences that military spouses undergo with deployments may be useful for therapists, chaplains, or military leaders to provide learning techniques on coping after deployments, promote longevity with military marriages through premarital workshops, chaplain-sponsored marital retreats, and marriage therapy for military spouses to promote marital happiness.
