Abstract
The Spiritual Assessment Inventory (SAI) is a multidimensional, self-report psychological scale developed by Todd W. Hall and Keith J. Edwards. It is designed to measure the quality and style of an individual’s personal relationship with God or a higher power, moving beyond simple metrics of religious practice or belief. Rooted in object relations and attachment theory applied to the divine, the SAI conceptualizes spiritual development as encompassing both adaptive (mature) and maladaptive (immature or conflicted) relational orientations. The scale is structured around key subscales that explore dimensions such as the sense of God’s presence, relational instability, and grandiosity in the spiritual domain.

Purpose
The primary purpose of the Spiritual Assessment Inventory (SAI) is to provide a theoretically grounded, psychometrically sound instrument for assessing the complexity of an individual’s spiritual life, particularly focusing on the dynamic, relational aspects of their connection with the divine. Unlike many earlier measures that focused solely on religious behaviors or well-being, the SAI seeks to diagnose potential areas of conflict, immaturity, or maladaptive patterns within the spiritual relationship, which are often overlooked in standard religious measures.
The scale is instrumental for researchers and clinicians interested in understanding how specific spiritual orientations (e.g., feelings of disappointment or grandiosity toward God) relate to overall psychological health, coping mechanisms, and personal adjustment. It was developed to specifically align with a theistic model of spiritual maturity.
Construct
The SAI measures spiritual development based on a theistic framework, drawing heavily from psychological theories of attachment and object relations. The core premise is that a person’s relationship with God mirrors, in many ways, their critical early relationships and relational patterns. The scale is structured into several core dimensions that represent adaptive and maladaptive relational styles:
- Awareness (A): Measures the individual’s subjective sense of God’s realness, presence, communication, and involvement in daily life. This is considered a fundamental aspect of mature spiritual experience.
- Realistic Acceptance (RA): Reflects the capacity to acknowledge relational conflict, disappointment, or frustration with God while maintaining the commitment and desire to continue the relationship. (This was formerly termed Healthy Ambivalence).
- Disappointment (D): Measures feelings of frustration, anger, or betrayal directed toward God, often resulting from unmet expectations or adverse life events. (This was formerly termed Defensiveness).
- Instability (I): Measures volatility, fear of rejection, and inconsistency in the relationship with God. This dimension often reflects insecure attachment patterns. (This was formerly termed Splitting).
- Grandiosity (G): Measures narcissistic spiritual tendencies, such as believing one is uniquely favored, more spiritual than others, or capable of manipulating God. (This was formerly termed Narcissism).
- Impression Management (IM): An experimental subscale designed to detect socially desirable responding regarding spiritual practices or attitudes.
Validity
The construct validity of the SAI was established through initial exploratory and confirmatory factor analyses during its development (1996, 2002), which supported the hypothesized factor structure corresponding to the five core dimensions (Awareness, Realistic Acceptance, Disappointment, Instability, and Grandiosity). Further validation work, including a study utilizing Item Response Theory (IRT) in 2007, confirmed that the items effectively measure the underlying latent traits of spiritual development and conflict.
The SAI demonstrates criterion-related validity by correlating its subscales with relevant psychological measures. Specifically, the adaptive scales (Awareness and Realistic Acceptance) typically show positive correlations with mental health indicators and mature coping strategies, while the maladaptive scales (Instability, Disappointment, Grandiosity) correlate positively with psychological distress, insecurity, and narcissistic traits.
Reliability
The SAI exhibits generally high internal consistency across its primary subscales, indicating that the items within each factor reliably measure the same underlying construct. The reliability coefficients (Cronbach’s alpha) reported in the source material demonstrate strong internal consistency for most dimensions, particularly Awareness and Disappointment.
Reported internal consistency values (Cronbach’s alpha coefficients) include:
- Awareness (A): Reported coefficients range from 0.90 to 0.95.
- Disappointment (D): Reported coefficients range from 0.90 to 0.91.
- Instability (I): Reported coefficients range from 0.84 to 0.88.
- Realistic Acceptance (RA): Reported coefficients range from 0.76 to 0.83.
- Grandiosity (G): This scale showed the lowest reliability, with coefficients ranging from 0.52 to 0.73, suggesting that this factor may require further refinement or is less stable across different samples.
Factor Analysis
The initial development of the SAI involved factor analysis which supported a multi-factor model of spiritual development. The 1996 study established the initial factors, which were refined in the 2002 publication into the five primary scales: Awareness, Realistic Acceptance, Disappointment, Instability, and Grandiosity. These factors successfully distinguish between two overarching categories of spiritual orientation: relational maturity (Awareness and Realistic Acceptance) and relational immaturity/conflict (Disappointment, Instability, and Grandiosity).
Subsequent psychometric analyses, including the 2007 Item Response Theory analysis, further confirmed the robust structure of the major factors, providing evidence that the scale items function appropriately across the continuum of spiritual experience. The scale also includes the experimental Impression Management scale, which is sometimes treated as a separate factor in exploratory analysis.
Instrument
Test Type: Self-report psychological assessment tool
Format: Multi-item questionnaire, typically consisting of 47 items (in the revised version), rated on a 5-point Likert scale.
Language Available: English (Primary Development)
Population Group: Individuals who hold a theistic worldview or engage in a personal, relational spirituality (e.g., Christians, monotheists).
Age Group: Adult (typically college-age and older)
Population Details: Developed primarily using Christian student and adult samples, reflecting the scale’s focus on a personal relationship with God.
Test Methodology: The respondent indicates the degree to which each statement is true for them using a 5-point scale, typically ranging from 1= Not At All True to 5=Very True. Scoring involves summing or averaging items specific to each subscale (A, RA, D, I, G, IM).

The initial version of the scale was developed in 1996, with a refined version (SAI-2) published and validated in 2002 and further analyzed in 2007. The scale is generally available for academic and research use, subject to standard citation requirements.
