Prayer is fairly prevalent in the United States. About 75% of Americans report praying at least once a week. However, the practice of prayer is more prevalent and practiced more consistently among Americans who perform other religious practices. There are four primary types of prayer in the West. Poloma and Pendleton, utilized factor analysis to delineate these four types of prayer: meditative (more spiritual, silent thinking), ritualistic (reciting), petitionary (making requests to God), and colloquial (general conversing with God). Further scientific study of prayer using factor analysis has revealed three dimensions of prayer. Ladd and Spilka's first factor was awareness of self, inward reaching. Their second and third factors were upward reaching (toward God) and outward reaching (toward others). This study appears to support the contemporary model of prayer as connection (whether to the self, higher being, or others).
