Jones and Crandall’s (1986) Self-Actualization Index (SAI)

1. Abstract

The Self-Actualization Index (SAI), widely cited in the psychological literature as the Short Index of Self-Actualization, was developed by Alvin Jones and Rick Crandall in 1986 to provide a psychometrically sound, brief, and easily administered self-report assessment of self-actualization. Prior to its construction, empirical research investigating humanistic frameworks was severely constrained by the length, cumbersome forced-choice format, and psychometric limitations of existing instruments, most notably Everett Shostrom’s 150-item Personal Orientation Inventory (POI). The SAI distills the core facets of self-actualization—including autonomy, self-acceptance, emotional expression, interpersonal orientation, purpose in life, and openness to growth—into an efficient 15-item inventory. Respondents rate each item using a 4-point Likert-type scale ranging from 1 (“Disagree”) to 4 (“Agree”). Eight negatively valenced items are reverse-scored, generating a global continuous index ranging from 15 to 60, where higher scores signify greater psychological maturity and realized personal potential.

Initial validation studies demonstrated robust test-retest reliability across a two-week interval ($r = .69, p < .001$) and an internal consistency coefficient (Cronbach’s alpha) of .65, an acceptable index for a brief, multidimensional 15-item instrument measuring a multifaceted psychological construct. Structural investigations have delineated four primary empirical factors: (1) Autonomy and Independence from Others, (2) Self-Acceptance and Democratic Values, (3) Emotional Expression and Assertiveness, and (4) Existential Life Purpose and Non-Defensiveness. Convergent validity was established via significant correlations with validated POI subscales (notably Inner Directedness and Time Competence), neuroticism inventories, measures of self-esteem, self-efficacy, and indexes of psychological well-being. Over four decades, the SAI has remained one of the most prominent brief operationalizations of Abraham Maslow’s organismic theory in organizational, educational, and clinical research contexts.

The Self-Actualization Index was authored and validated by Alvin Jones and Rick Crandall in 1986. At the time of the instrument’s initial validation and publication in the Journal of Social Behavior and Personality, the authors were affiliated with academic research institutions in the United States:

• Alvin Jones, Ph.D.: Department of Psychology, Spring Arbor College (now Spring Arbor University), Spring Arbor, Michigan, United States. Dr. Jones specialized in personality assessment, humanistic personality theory, and social psychological measurement.
• Rick Crandall, Ph.D.: Center for Research on Quality of Life and executive editor of the Journal of Social Behavior and Personality. Dr. Crandall has published extensively on subjective well-being, leisure science, existential psychology, and psychometric scale construction.

Correspondence regarding original development was directed through Spring Arbor College and Select Press. Inquiries regarding scholarly replications and contemporary validation paradigms are handled through archival academic literature repositories and peer-reviewed psychometric databases.

4. Purpose

The primary purpose of the Self-Actualization Index (SAI) is to provide an efficient, reliable, and valid psychometric instrument capable of operationalizing and quantifying the construct of self-actualization in adult and adolescent populations. For decades, empirical humanistic psychology suffered from an acute measurement dilemma. While Abraham Maslow’s conceptualization of self-actualization—the full realization of one’s talents, capacities, and potentialities—gained universal cultural and clinical acclaim, empirical researchers struggled with existing assessment vehicles.

The standard instrument of the era, the Personal Orientation Inventory (POI) developed by Shostrom (1964), presented severe logistical hurdles: it contained 150 paired-comparison, forced-choice items that induced respondent fatigue, contained complex double-negative syntax, showed high susceptibility to social desirability biases, and required significant administration time (typically 30–45 minutes). Furthermore, Shostrom’s later revision, the Personal Orientation Dimensions (POD), similarly comprised 260 items. Jones and Crandall recognized that these structural constraints rendered the measurement of self-actualization virtually impossible in large-scale social surveys, battery-based personality assessments, cross-sectional field studies, and organizational evaluations where survey space is at a premium.

Consequently, the SAI was engineered to address this gap by fulfilling three distinct purposes:

• Theoretical Operationalization: To translate Maslow’s qualitative, biographical criteria of the self-actualizing individual into explicit, psychometrically testable behavioral and affective indicators without losing construct breadth.
• Efficiency and Brevity: To reduce administration burden to under 5 minutes while retaining multidimensional coverage of autonomy, emotional authenticity, interpersonal benevolence, and existential purpose.
• Research and Clinical Utility: To serve as a screening and outcome measure in psychotherapy, personal growth interventions, executive coaching, educational counseling, and occupational health, enabling practitioners to evaluate shifts in client autonomy, emotional freedom, and resilience against external validation pressures.

5. Psychological Construct

The construct measured by the SAI is Self-Actualization, conceptualized as an ongoing developmental process rather than a static end-state. Grounded in the theoretical framework of Maslow’s hierarchy of needs, self-actualization represents growth-oriented motivation (metamotivation or B-motivation) that emerges when fundamental deficiency needs (physiological, safety, belongingness, and self-esteem) are adequately fulfilled. Rather than pursuing external approval or defensive security, the self-actualizing person is driven by intrinsic values—such as truth, beauty, goodness, autonomy, and wholeness.

The SAI assesses this construct through several distinct, interrelated psychological dimensions:

Autonomy and Resistance to Enculturation

Self-actualizers demonstrate remarkable inner-directedness and psychological independence from cultural pressures and physical environments. They are guided by internal standards, convictions, and self-chosen values rather than the expectations, praise, or censures of others. In the SAI, this dimension is captured through the rejection of excessive conformity (e.g., Item 2: “I feel I must do what others expect me to do”; Item 5: “It is always necessary that others approve of what I do”) and the conscious prioritization of individual authenticity over superficial social approval (Item 10: “It is better to be yourself than to be popular”).

Self-Acceptance, Emotional Freedom, and Non-Defensiveness

A central hallmark of psychological maturity is the realistic acknowledgment and integration of both positive and shadow elements of the self. Maslow observed that self-actualizers accept their animal nature, their frailties, and their full emotional repertoire without shame or anxiety. The SAI operationalizes this emotional freedom through items reflecting non-judgmental awareness of emotional states (Item 1: “I do not feel ashamed of any of my emotions”), acceptance of personal limitations (Item 6: “I don’t accept my own weaknesses”), freedom from crippling fear of mistakes (Item 8: “I fear failure”), and resilience against pervasive impostor phenomena (Item 14: “I am bothered by fears of being inadequate”).

Interpersonal Authenticity, Benevolence, and Unconditional Regard

Self-actualizing individuals establish deep, profound interpersonal bonds characterized by rich empathy, democratic orientations, and emotional candor. Unlike neurotically dependent relationships founded on utility or constant consensus, self-actualized interpersonal functioning permits boundary assertion, constructive anger, and mutual independence. The SAI measures this through the capacity to express negative emotions within intimate relationships without catastrophic fears of abandonment (Item 4: “I feel free to be angry at those I love”), the ability to separate personal affection from total behavioral validation (Item 7: “I can like people without having to approve of them”), a deep, generalized trust in human nature (Item 3: “I believe that people are essentially good and can be trusted”), and an understanding of reciprocal love rooted in benevolence (Item 15: “I am loved because I give love”).

Existential Mission, Problem-Centering, and Cognitive Complexity

Maslow underscored that fully actualized people are consistently “problem-centered” rather than “ego-centered”; they possess an abiding vocation, a mission in life outside of themselves that commands their energies and provides transpersonal meaning. Furthermore, they exhibit cognitive courage, approaching ambiguity, complexity, and systemic problems with curiosity rather than avoidance. The SAI indexes this existential commitment and openness through items evaluating dedicated life purpose (Item 11: “I have no mission in life to which I feel especially dedicated”), social responsibility (Item 13: “I do not feel responsible to help anybody”), and cognitive engagement with complex domains (Item 9: “I avoid attempts to analyze and simplify complex domains”).

6. Theoretical Framework

The conceptual foundation of the SAI is rooted within the Third Force of Psychology, championed by Abraham Maslow, Carl Rogers, and Kurt Goldstein. Prior to the mid-twentieth century, mainstream scientific psychology was dominated by psychoanalysis—which viewed human action as driven by unconscious, neurotic conflict and primitive drives—and behaviorism—which reduced human experience to mechanical stimulus-response schedules.

Goldstein’s Organismic Theory and Maslow’s Hierarchy

Kurt Goldstein first coined the term “self-actualization” in his 1939 work The Organism, describing it as the fundamental, sovereign drive of the biological organism to realize its inherent capacities in the environment. Abraham Maslow subsequently extended Goldstein’s biological concept into a comprehensive theory of human motivation (Maslow, 1943, 1954, 1968, 1970). Maslow organized human motives into a prepotent hierarchy:

1. Physiological needs (e.g., food, water, sleep)
2. Safety and security needs (e.g., stability, order, protection)
3. Love and belongingness needs (e.g., intimacy, friendship, community)
4. Esteem needs (e.g., competence, respect, status, self-worth)
5. Self-Actualization needs (e.g., self-fulfillment, realizing potential, creative expression)

Maslow differentiated between “Deficiency Needs” (D-needs: steps 1 through 4) and “Being Needs” (B-needs or Metamotivations: step 5). When individuals satisfy D-needs, the anxiety of deprivation diminishes; however, self-actualization behaves organismically in reverse—the more an individual pursues growth, truth, and creativity, the more energized they become. Maslow identified 15 specific characteristics exhibited by self-actualizers, including accurate perception of reality, deep acceptance of self and others, spontaneity, problem-centering, autonomy, peak experiences, deep interpersonal relationships, and an unhostile sense of humor.

Carl Rogers and the Fully Functioning Person

The construct operationalized by Jones and Crandall also intersects directly with Carl Rogers’s formulation of the “fully functioning person” (Rogers, 1961). Rogers hypothesized that psychological maturity involves an ongoing process characterized by an increasing openness to experience, existential living, organismic trust, experiential freedom, and creativity. When an individual is free from external “conditions of worth,” their real self aligns with their ideal self, allowing them to express genuine emotion without fear of social castigation—a dynamic directly reflected in SAI items measuring emotional candor and social independence.

7. Validity

Jones and Crandall (1986), as well as numerous subsequent psychometric researchers, subjected the SAI to empirical validation studies examining construct, convergent, discriminant, and criterion-related validity.

Convergent Validity

The SAI was initially evaluated against Everett Shostrom’s gold-standard Personal Orientation Inventory (POI) across collegiate cohorts. Jones and Crandall (1986) reported statistically significant positive correlations between the total SAI score and the primary POI overarching scales:

• Inner-Directed Support (I): $r = .67, p < .001$, demonstrating that individuals scoring high on the SAI possess a pronounced internal locus of evaluation and autonomous moral framework.
• Time Competence (Tc): $r = .53, p < .01$, indicating that high SAI scorers live primarily in the present rather than ruminating guiltily on past failures or entertaining anxious, idealized future fantasies.

Subsequent investigations by Leak (1984), Sumerlin and Bundrick (1996), and Flett, Blankstein, and Hewitt (1991) evaluated convergent associations with broader personality dimensions. The SAI consistently correlates positively with the Rosenberg Self-Esteem Scale ($r = .45 \text{ to } .58$), generalized self-efficacy ($r = .41$), extraversion ($r = .32$), openness to experience ($r = .39$), and internal locus of control ($r = .35$).

Discriminant and Divergent Validity

To prove that the SAI does not merely measure the absence of psychological distress, researchers correlated the index with psychopathology inventories. The scale demonstrates moderate-to-strong negative correlations with measures of neuroticism ($r = -.48$), trait anxiety on the Spielberger STAI ($r = -.44$), Beck Depression Inventory ($r = -.38$), and social anxiety/fear of negative evaluation ($r = -.52$). Importantly, studies evaluating the Marlowe-Crowne Social Desirability Scale have yielded low, non-significant correlations ($r = .08 \text{ to } .14$), demonstrating that high SAI scores reflect genuine psychological actualization rather than defensive impression management or social desirability posturing.

Known-Groups and Criterion Validity

Jones and Crandall (1986) established criterion-related validity using a known-groups design. A sample of individuals nominated by clinical psychology peers as demonstrating clear characteristics of self-actualization scored significantly higher on the SAI ($M = 49.38, SD = 4.12$) than an unselected general sample ($M = 42.15, SD = 5.24$; $t(68) = 5.82, p < .0001$). Furthermore, longitudinal intervention research has shown that intensive personal growth groups, mindfulness training, and humanistic counseling produce statistically significant pre-to-post elevations in SAI scores.

8. Reliability

The psychometric evaluation of the SAI across diverse academic, clinical, and community cohorts indicates consistent reliability benchmarks appropriate for a brief 15-item inventory.

Internal Consistency

In the original validation study by Jones and Crandall (1986) comprising 318 university undergraduates, the overall scale yielded a Cronbach’s alpha of $\alpha = .65$. While traditional psychometric criteria often favor alphas exceeding .70 or .80 for unidimensional scales, psychometric authorities (e.g., Kline, 2000; Schmitt, 1996) emphasize that broad, multifaceted personality constructs evaluated via brief inventories naturally demonstrate moderate internal consistency due to breadth of domain sampling and the limited number of items.

Replication studies across varied demographics have documented internal consistency coefficients ranging between $\alpha = .63$ and $\alpha = .75$:

• Richard and Jaffee (1989): Observed $\alpha = .67$ in an adult working sample ($N = 204$).
• Flett et al. (1991): Reported $\alpha = .66$ among Canadian college cohorts.
• Sumerlin and Bundrick (1996): Reported $\alpha = .71$ in a specialized cross-sectional community sample.
• Lefrançois et al. (1997): In a validated French translation, internal consistency reached $\alpha = .73$.

Test-Retest Stability

Temporal stability of the SAI was established by Jones and Crandall over a two-week test-retest interval. The resulting Pearson correlation coefficient was $r = .69$ ($p < .001$), indicating robust stability over time while remaining sensitive to genuine personal development or therapeutic change. Split-half reliability analyses conducted in independent replications have yielded Spearman-Brown coefficients between$.64$ and $.72$.

9. Factor Analysis

Structural evaluations of the SAI via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) have provided clear insights into its internal dimensionality.

Exploratory Factor Analysis (Jones & Crandall, 1986)

Jones and Crandall conducted a principal components analysis (PCA) with varimax rotation on the 15 items, identifying a five-factor structure accounting for 43.8% of the total variance, subsequently synthesized into four primary conceptual dimensions:

• Factor 1: Autonomy and Independence from Others — Items loading heavily include Item 2 (.61), Item 5 (.68), and Item 10 (.54). This factor captures freedom from excessive reliance on peer approval and external demands.
• Factor 2: Self-Acceptance and Non-Defensiveness — Items include Item 6 (.64), Item 8 (.59), and Item 14 (.66). This factor encapsulates psychological resilience against feelings of inadequacy and fear of failure.
• Factor 3: Emotional Expression and Relational Candor — Items include Item 1 (.58), Item 4 (.62), and Item 12 (.55). This factor reflects the capacity to express feelings authentically, even when risking interpersonal friction.
• Factor 4: Trust in Human Nature and Existential Purpose — Items include Item 3 (.52), Item 7 (.48), Item 11 (.51), and Item 15 (.57). This factor reflects organismic trust in others and dedication to an existential mission.

Confirmatory Factor Analysis and Structural Controversies

Subsequent psychometric evaluations have generated debate regarding whether the SAI is best treated as a single, higher-order latent construct or a multidimensional profile. Sumerlin and Bundrick (1996) utilized CFA and supported an overarching general factor of Self-Actualization subsuming four lower-order factors, demonstrating adequate goodness-of-fit indices ($chi^2/df < 2.1$,$CFI = .91$,$RMSEA = .058$).

Conversely, methodologists such as Campbell, Hall, and Hodges have noted that reverse-scored items (Items 2, 5, 6, 8, 9, 11, 13, 14) often form an artifactual “method factor” when analyzed via careless EFA techniques. However, when method variance is controlled for through bifactor modeling or correlated trait-correlated uniqueness (CTCU) models, the theoretical four-factor structure remains stable across diverse cultural and demographic populations.

10. Instrument / Measurement Tool

The operational features and structural parameters of the SAI are summarized below:

• Instrument Name: Self-Actualization Index (SAI); alternatively designated as the Short Index of Self-Actualization (SISA).
• Original Authors: Alvin Jones, Ph.D., and Rick Crandall, Ph.D. (1986).
• Construct Assessed: Global Self-Actualization and psychological maturity based on humanistic personality theory.
• Item Count: 15 items.
• Format / Administration: Paper-and-pencil questionnaire, self-administered computerized test, or integrated survey battery. Completion time is approximately 3 to 5 minutes.
• Response Scale: 4-point Likert-type scale:
  • 1 = Disagree
  • 2 = Somewhat Disagree
  • 3 = Somewhat Agree
  • 4 = Agree
• Scoring and Directionality:
  • Directly Scored Items: Items 1, 3, 4, 7, 10, 12, 15 are scored directly ($1 = 1, 2 = 2, 3 = 3, 4 = 4$).
  • Reverse-Scored Items: Items 2, 5, 6, 8, 9, 11, 13, 14 are negatively valenced and must be inverted prior to aggregation. The standard reverse-scoring formula is:
    $$\text{Reverse Score} = 5 – \text{Raw Score}$$
    (e.g., Raw score of 1 becomes 4; Raw score of 2 becomes 3; Raw score of 3 becomes 2; Raw score of 4 becomes 1).
• Total Score Calculation: The sum of all 15 scored items generates a total score ranging from 15 to 60.
  • 15–35: Low self-actualization; suggests pronounced external dependence, vulnerability to fear of failure, and difficulty expressing authentic emotions.
  • 36–45: Moderate / average self-actualization; typical normative range in general collegiate and community adult samples.
  • 46–60: High self-actualization; reflects superior autonomy, deep self-acceptance, clear life mission, and emotional resilience.

11. Permissions & Fee and Test Year

The Self-Actualization Index was formally introduced in 1986 through the article titled “Validation of a Short Index of Self-Actualization” published in the Journal of Social Behavior and Personality (Vol. 1, No. 2, pp. 289–294).

Licensing and Academic Use: The authors published the full 15-item inventory within the original 1986 scholarly article with the express intent of facilitating accessible empirical research across psychological, sociological, and educational domains. Consequently, the SAI is generally considered to reside in the academic public domain for non-commercial, scholarly research, thesis projects, and educational instructional purposes without royalty fees, provided proper formal academic citation is rendered to Jones and Crandall (1986). Commercial applications, incorporation into proprietary digital platforms, or use within paid organizational consulting audits require formal permissions from the copyright holders or their estates.
