The Structure of Prayer Scale<\/strong> (SPS; Luckow, Ladd, Spilka, McIntosh, Parks, & Laforett, 1997) is a multidimensional psychometric instrument developed within the psychology of religion<\/a> to assess the diverse cognitive, behavioral, affective, and liturgical dimensions of private and communal prayer practices. While historical operationalizations of prayer often treated it as a unidimensional frequency variable (e.g., how often an individual prays), psychometricians have increasingly demonstrated that prayer represents a complex, differentiated cognitive-affective coping system. The SPS operationalizes prayer across six empirical dimensions: Confession<\/em> (5 items), Petition<\/em> (3 items), Ritual<\/em> (3 items), Meditation-Improvement<\/em> (5 items), Habit<\/em> (4 items), and Compassionate Petition<\/em> (8 items). Comprising 28 items rated on a 6-point Likert scale<\/a> ranging from 1 (strongly disagree<\/em>) to 6 (strongly agree<\/em>), the instrument facilitates granular investigation into how specific prayer modalities correlate differentially with psychological well-being, religious coping, depressive symptom reduction, forgiveness processes, and subjective health outcomes. Validation research yields varying yet theoretically coherent internal consistency estimates across subscales, ranging from moderate to high reliability (Cronbach’s α = .44 to .95). This article provides a comprehensive academic analysis of the SPS, examining its psychometric taxonomy, theoretical foundations within attribution and coping theory, construct validity evidence, structural factor configurations, administration parameters, and clinical utility<\/span>.<\/p>\n Structure of Prayer Scale, prayer dimensions, psychology of religion, religious coping, petitionary prayer, contemplative prayer, psychometrics, spiritual assessment, mental health, Bernard Spilka, Kevin L. Ladd.<\/p>\n The Structure of Prayer Scale was conceptualized, designed, and psychometrically validated through collaborative research led by Anne Luckow<\/strong>, Kevin L. Ladd<\/strong>, Bernard Spilka<\/strong>, Daniel N. McIntosh<\/strong>, Cynthia Parks<\/strong>, and Daniele Laforett<\/strong> (1997) at the University of Denver and affiliated research institutions.<\/p>\n The primary purpose of the Structure of Prayer Scale is to overcome the empirical limitations of reductionist, single-item religious indicators. In early epidemiologic and social-psychological literature, prayer was frequently indexed solely by behavioral frequency (e.g., “How many times a day or week do you pray?”). This methodology obscured vital qualitative variations in religious functioning. Two individuals who report daily prayer may engage in fundamentally distinct phenomenological experiences: one may engage in rote, anxious, or guilt-driven supplication aimed at obtaining material favors, whereas the other may engage in mystical communion, introspective self-regulation, or altruistic intercession for suffering communities. The SPS serves several distinct scientific and clinical purposes:<\/p>\n The SPS operationalizes prayer not as an undifferentiated mystical impulse, but as a structured behavioral, cognitive, and affective coping system. The instrument measures six specific psychological constructs:<\/p>\n The Confession<\/em> subscale assesses prayers centered on moral introspection, moral accounting, disclosure of personal shortcomings, guilt alleviation, and the pursuit of spiritual reconciliation (e.g., Item 3: “It is important to me to tell God about my sins or faults”<\/em>; Item 17: “When I pray, I confess to God the things I should not have done”<\/em>). Theoretically, this construct reflects cognitive-affective self-regulation wherein the individual confronts personal transgressions within an perceived supportive, transcendent relationship, facilitating catharsis, moral clarity, and relief from internal conflict.<\/p>\n The Petition<\/em> subscale measures self-interested or instrumental prayer aimed at securing concrete outcomes, material advantages, personal assistance, or problem resolution (e.g., Item 13: “I must admit that I usually prayer to get something”<\/em>; Item 15: “When I pray, I ask God for special favors”<\/em>). This construct is frequently associated with an external locus of control or transactional spiritual schema, wherein prayer functions primarily as a request for divine intervention in personal dilemmas.<\/p>\n The Ritual<\/em> dimension evaluates the formal, ordered, and standardized mechanics of prayer (e.g., Item 1: “When I pray alone, I have a ritual that I adhere to strictly”<\/em>; Item 20: “When I pray, I have certain words of phrases that I repeat a number of times”<\/em>). In cognitive terms, ritual prayer relies on structured liturgical scripts, repetitive verbal formulations, and orderliness, providing cognitive containment and behavioral predictability during existential uncertainty.<\/p>\n The Meditation-Improvement<\/em> subscale measures inward-directed contemplative prayer, emotional centering, personal transformation, and spiritual communion (e.g., Item 2: “Through deep pray I am able to know God better”<\/em>; Item 16: “Prayer helps me keep my life balanced and happy”<\/em>; Item 26: “Prayer is a way for me to connect with my inner spirit”<\/em>). This construct captures the integrative, self-actualizing functions of spiritual devotion, aligning closely with intrinsic religious motivation and contemplative mindfulness.<\/p>\n The Habit<\/em> subscale indexes situational, automatic, and scheduled religious routines tied to circadian or behavioral cues (e.g., Item 10: “I usually say a prayer before each meal”<\/em>; Item 12: “I always pray before I go to sleep”<\/em>; Item 28: “I pray daily”<\/em>). Rather than assessing the subjective content of prayer, Habit reflects behavioral automaticity, socialization, and the integration of prayer practices into daily living scripts.<\/p>\n The Compassionate Petition<\/em> dimension taps intercessory, other-oriented, grateful, and altruistic prayer (e.g., Item 11: “I like to say prayers for people about whom I care very much”<\/em>; Item 19: “I ask God to help others when I am unable to”<\/em>; Item 6: “I pray to give thanks for all God has done for me”<\/em>). This construct synthesizes prosocial empathy, gratitude, and communal responsibility, reflecting an outward-focused spiritual orientation wherein the petitioner acts as a moral and emotional proxy for others.<\/p>\n The conceptual architecture of the Structure of Prayer Scale is grounded primarily in the cognitive-attributional framework of religion advanced by Bernard Spilka (Spilka, Shaver, & Kirkpatrick, 1985) and the cognitive-phenomenological prayer models later developed by Kevin L. Ladd (Ladd & Spilka, 2002, 2006). This theoretical tradition asserts that religious thought and behavior represent meaning-making mechanisms designed to satisfy three universal human motivations: the need for meaning, the need for control over outcomes, and the need for self-esteem and belonging.<\/p>\n Historically, psychological conceptualizations of prayer evolved through several paradigms:<\/p>\n Validation studies across clinical, community, and university cohorts demonstrate robust construct, convergent, discriminant, and predictive validity for the Structure of Prayer Scale:<\/p>\n Construct validity has been established through continuous factor-analytic investigations demonstrating that the six-factor configuration accounts for significantly greater variance in religious behavior than competing unidimensional or two-factor models (such as simply contrasting “internal” vs. “external” prayer). Factor structures hold across both collegiate and adult community samples (Luckow et al., 1997; Ladd & Spilka, 2002).<\/p>\n Extensive research demonstrates the predictive utility of the SPS regarding health and clinical indices:<\/p>\n The internal consistency of the Structure of Prayer Scale has been investigated across diverse adult, undergraduate, and health-related cohorts. Reliability coefficients (α) vary across subscales due to variations in item length and sample characteristics:<\/p>\n Test-retest reliability assessments conducted across 4- to 8-week intervals indicate high temporal stability for the structural traits, with stability coefficients generally exceeding r<\/em> = .75 for Habit, Ritual, and Compassionate Petition, confirming that the scale assesses sustained individual patterns of prayer rather than momentary emotional states<\/span>.<\/p>\n The psychometric structure of the SPS was established via exploratory factor analysis (EFA) and subsequent confirmatory factor analysis (CFA) during its initial development and subsequent replications (Luckow et al., 1997; Ladd & Spilka, 2002):<\/p>\n Initial item pools capturing over 60 behavioral, liturgical, and emotional manifestations of prayer were subjected to Principal Axis Factoring (PAF) and Principal Component Analysis (PCA) with both orthogonal (Varimax<\/a>) and oblique (Promax<\/a>) rotations. Oblique rotation was prioritized theoretically, as dimensions of prayer are naturally interrelated components of an overarching religious lifestyle.<\/p>\n Factor retention based on the Kaiser criterion (eigenvalues > 1.0) and scree plot inspection confirmed a stable six-factor solution accounting for approximately 52% to 61% of total item variance across validation cohorts. Primary item loadings on target factors ranged from .45 to .84, with minimal secondary cross-loadings (< .30)<\/span>.<\/p>\n Confirmatory investigations testing the 6-factor oblique model have confirmed superior fit compared to alternative 1-factor or 3-factor nested models. Typical reported fit metrics in representative validation studies (e.g., de la Mora, 2004; Ladd & Spilka, 2002) include:<\/p>\n The Structure of Prayer Scale is a self-administered, 28-item psychometric questionnaire.
