Mental, Physical, and Spiritual Well-Being Scale

Abstract

The Mental, Physical, and Spiritual Well-Being Scale (MPSWS; also referred to in literature as the MPS Well-Being Scale) is a multidimensional psychometric instrument formulated by Australian psychologists Dianne A. Vella-Brodrick and Felicity C. Allen in 1995. Grounded in holistic health philosophy and salutogenic theory, the scale operationalizes human health beyond the mere absence of pathology by simultaneously appraising three fundamental, interdependent domains: mental (intellectual, cognitive, and aesthetic engagement), physical (somatic vitality, absence of debilitating symptoms, and bodily equilibrium), and spiritual well-being (existential meaning, transcendental connection, and the pursuit of inner peace). Comprising 30 self-report items evaluated primarily on a 5-point Likert continuum ranging from 1 (Often) to 5 (Never), the instrument incorporates both positively and negatively keyed (reverse-scored) indicators to mitigate acquiescence response set bias. Psychometric investigations across diverse adult and university cohorts have confirmed satisfactory internal consistency, with Cronbach’s alpha coefficients generally ranging between .70 and .86 for the overall composite and constituent subscales. Exploratory and confirmatory factor analyses demonstrate a robust three-factor orthogonal or correlated structure, differentiating cognitive cultivation, somatic health, and transpersonal orientation. Furthermore, empirical validation against established measures of social desirability, affectivity, and subjective quality of life indicates strong convergent and discriminant validity, positioning the MPSWS as an efficacious assessment tool in clinical health psychology, positive psychology, and strengths-based social work interventions.

Authors

The Mental, Physical, and Spiritual Well-Being Scale was conceptualized, developed, and validated through the collaborative academic efforts of:

• Dianne A. Vella-Brodrick, Ph.D.: Professor and Director of the Centre for Wellbeing Science at the Melbourne Graduate School of Education, University of Melbourne, Victoria, Australia. Formerly affiliated with the Department of Psychology at Monash University (Caulfield Campus), Dr. Vella-Brodrick is an internationally recognized scholar in positive psychology, adolescent flourishing, and the empirical measurement of well-being interventions.
• Felicity C. Allen, Ph.D.: Former Senior Lecturer in the Department of Psychology at Monash University, Victoria, Australia. Dr. Allen has authored foundational research exploring health psychology, stress coping mechanisms, biopsychosocial paradigms, and holistic dimensions of human longevity and wellness.

Purpose

The primary purpose of the Mental, Physical, and Spiritual Well-Being Scale is to provide a unified, empirically sound measurement tool that captures an individual’s multi-tiered wellness status across biological, cognitive-cultural, and existential-spiritual axes. Historically, clinical assessment instruments emerged predominantly from biomedical and psychiatric traditions focused almost exclusively on the quantification of symptomatology, deficit states, and psychopathological entities (e.g., depressive symptomatology, generalized anxiety, somatization). Vella-Brodrick and Allen recognized that such deficit-oriented paradigms fail to capture positive human functioning, vitality, and proactive health maintenance.

In research contexts, the MPSWS was designed to overcome the fragmentation prevalent in behavioral medicine, where researchers frequently administered disparate, uncoordinated scales to measure physical symptoms, cognitive functioning, and religious or spiritual coping independently. By synthesizing these tripartite dimensions within a single, parsimonious 30-item instrument, the MPSWS facilitates the empirical investigation of cross-domain synergy—such as how spiritual practices buffer somatic discomfort, or how intellectual and aesthetic curiosity sustains psychological resilience during periods of chronic illness.

In applied clinical and counseling settings, the MPSWS functions as a comprehensive, strengths-based diagnostic and outcome assessment device. Rather than cataloging diagnoses in isolation, mental health counselors, clinical psychologists, and social workers utilize the MPSWS to profile a client’s biopsychospiritual resources. For instance, an individual presenting with elevated physical distress or psychosomatic complaints (e.g., frequent headaches, gastrointestinal upset, lethargy) might demonstrate preserved spiritual well-being (e.g., systematic engagement in prayer, meditation, or moral self-reflection) and high mental curiosity (e.g., consumption of literature, artistic engagement). Identifying these intact dimensions permits clinicians to formulate tailored, strengths-based psychotherapeutic treatment plans that mobilize existential and cognitive assets to alleviate somatic and emotional strain.

Psychological Construct

The MPSWS is predicated on a holistic conceptualization of human well-being, operationalizing the construct through three primary, non-redundant dimensions:

1. Mental Well-Being (MWB)

Within the MPSWS architecture, mental well-being is not defined merely as the subjective absence of psychological distress, neurosis, or affective turbulence. Rather, it is operationalized as active intellectual engagement, cognitive vitality, open-minded epistemological curiosity, aesthetic appreciation, and reflective moral deliberation. Items mapped onto this domain assess intentional behaviors aimed at expanding the intellect and enriching subjective culture. Examples include viewing instructional documentaries and news programs, reading novels, engaging in mentally challenging problem-solving activities (e.g., crosswords, chess, bridge), visiting cultural institutions (e.g., museums, galleries, theaters), creating aesthetically pleasing home or work environments, and collecting comprehensive information before forming critical judgments. Thus, mental well-being reflects cognitive openness, epistemic vigilance, and active engagement with cultural capital.

2. Physical Well-Being (PWB)

The physical well-being subscale captures subjective bodily equilibrium, perceived vitality, and the relative absence of debilitating, functional somatic complaints. Grounded in behavioral medicine, this dimension recognizes that perceived somatic integrity profoundly colors psychological experience. The construct encompasses indicators of energy balance and recuperation (such as waking rested and alert versus experiencing pervasive lethargy and fatigue), peripheral autonomic equilibrium (e.g., having comfortably warm hands and feet), and proactive somatic regulation (e.g., monitoring dietary intake). Concurrently, it incorporates an appraisal of common functional somatic symptoms over past-month and past-year intervals, including recurrent gastrointestinal distress (diarrhea, constipation, indigestion, nausea, vomiting) and tension-related physical complaints (frequent headaches, musculoskeletal aches and pains).

3. Spiritual Well-Being (SWB)

Spiritual well-being within the MPSWS encompasses both traditional religious orientations and broad existential, transpersonal constructs. It assesses an individual’s search for ultimate meaning, moral cultivation, and transcendence, irrespective of strict sectarian affiliation. Key indicators evaluate the mobilization of transcendent support during crisis periods (e.g., reaching out to a higher power, prayer, clergy, or places of worship), regular engagement in contemplative disciplines aimed at cultivating equanimity (e.g., meditation, yoga, formal prayer), belief in transcendent continuity (e.g., life after death), and ongoing self-analysis geared toward moral improvement. Additionally, it appraises conversational engagement regarding existential themes (e.g., purpose in life, death, nature of the soul) and the temporal stability of inner peace practices, assessing longitudinal dedication to self-transcendent disciplines.

Theoretical Framework

The theoretical infrastructure of the MPSWS is anchored in holistic health frameworks, Aaron Antonovsky’s salutogenesis model, and the World Health Organization’s foundational 1948 charter definition of health as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.”

Antonovsky’s salutogenic paradigm posits that life is inherently stressful and entropic; therefore, psychometric inquiry must investigate the generalized resistance resources (GRRs) that enable individuals to maintain coherence and health. The MPSWS incorporates this view by conceptualizing mental stimulation and spiritual contemplation as internal resources that fortify the organism against environmental and somatic stressors. Rather than positioning mind, body, and spirit as dualistic or tripartite compartmentalized entities, the scale relies on a biopsychospiritual systems model, initially popularized in clinical medicine by George Engel and subsequently expanded in behavioral medicine to incorporate existential dimensions.

Furthermore, the scale aligns with psychological models of optimal functioning, such as Carol Ryff’s Model of Psychological Well-Being and Self-Determination Theory. Ryff posited that personal growth and purpose in life are essential constituents of positive psychological adjustment. Similarly, the MPSWS conceptualizes spiritual practices and intellectual curiosity not merely as leisure pursuits, but as essential self-regulatory behaviors that fulfill human needs for competence, autonomy, and existential coherence. The integration of somatic symptom appraisal acknowledges psychoneuroimmunological pathways, wherein psychological and spiritual distress manifests somatically, while physical vigor serves as a physical foundation supporting cognitive and contemplative pursuits.

Validity

Extensive psychometric investigations have established the construct, convergent, discriminant, and criterion-related validity of the Mental, Physical, and Spiritual Well-Being Scale across adult community cohorts, university samples, and clinical environments.

Construct and Factorial Validity

Construct validity was established during initial development through comprehensive content analysis, expert panel reviews, and factor-analytic procedures (Vella-Brodrick & Allen, 1995). The authors systematically examined whether the 30 items loaded significantly onto their theorized latent constructs without excessive cross-loadings. Independent evaluations conducted by researchers such as Green (2006) further validated the dimensional stability across unique socio-demographic samples, supporting the distinctiveness of the physical, mental, and spiritual subcomponents.

Convergent Validity

The convergent validity of the MPSWS subscales has been corroborated via robust correlations with established psychometric benchmarks:

• Physical Well-Being: Demonstrates strong negative correlations with somatic symptom inventories, physical illness reporting checklists, and measures of chronic fatigue, alongside significant positive associations with general physical health visual analog scales and functional status indexes.
• Mental Well-Being: Correlates significantly positively with scales measuring intellectual curiosity, Need for Cognition (NFC), openness to experience from the Five-Factor Model of personality, and creative engagement indices.
• Spiritual Well-Being: Displays substantial positive correlations with validated spiritual assessment instruments, including Paloutzian and Ellison’s Spiritual Well-Being Scale (SWBS), the Purpose in Life Test (PIL), and measures of intrinsic religiosity and existential purpose.

Discriminant Validity and Social Desirability

A crucial consideration in positive psychology instruments is ensuring that self-reported well-being does not merely reflect a pervasive response bias or an effort to project a socially favorable impression. Vella-Brodrick and White (1997) explicitly evaluated the influence of the social desirability response set on the MPSWS using the Marlowe-Crowne Social Desirability Scale. Their findings demonstrated that while modest correlations emerged between certain socially approved behaviors and spiritual/moral self-analysis items, the magnitude of these correlations did not account for the variance observed in the subscales. This confirmed that the MPSWS measures substantive, distinct psychological dimensions rather than artifactual impression management.

Reliability

The psychometric reliability of the MPSWS has been documented via internal consistency analysis and temporal stability assessments across diverse investigations.

Internal Consistency

In the seminal validation study by Vella-Brodrick and Allen (1995), the composite scale and its constituent subscales demonstrated solid internal consistency coefficients:

• Spiritual Well-Being Subscale: Consistently yields high internal reliability, with Cronbach’s alpha ($\alpha$) coefficients typically ranging between .80 and .86, reflecting substantial homogeneity among the existential, contemplative, and religious coping items.
• Physical Well-Being Subscale: Exhibits internal consistency coefficients generally falling between .75 and .82, which is deemed acceptable to good for somatic checklist-derived psychological scales representing diverse bodily organ systems (e.g., gastrointestinal, cephalic, peripheral circulatory).
• Mental Well-Being Subscale: Typically reports Cronbach’s alpha values ranging from .70 to .78. The slightly lower alpha is psychometrically normative given the broad heterogeneity of the cognitive-cultural domain (spanning novel reading, documentary viewing, game playing, and environmental aesthetics).
• Total MPSWS Composite: Demonstrates overall internal consistency reliability coefficients regularly exceeding .83 to .88 across normative cohorts.

Test-Retest Reliability

Evaluations of temporal stability across short-term test-retest intervals (ranging from two to four weeks) have shown stable intraclass correlation coefficients ($r_{tt} > .75$), indicating that the instrument captures enduring lifestyle patterns, chronic somatic tendencies, and established philosophical outlooks rather than transient situational fluctuations or acute affective states.

Factor Analysis

The underlying factor structure of the MPSWS was initially investigated by Vella-Brodrick and Allen (1995) using Exploratory Factor Analysis (EFA) with principal axis factoring and both orthogonal (Varimax) and oblique (Oblomax/Promax) rotations to assess whether the underlying latent factors operated independently or interdependently.

The empirical extraction criteria—including Kaiser’s eigenvalue-greater-than-one rule and Cattell’s scree test inspection—consistently isolated three dominant latent dimensions that accounted for a substantial proportion of the total item variance. The primary factors mapped directly onto the theoretical taxonomy:

1. Factor 1: Spiritual Well-Being: Loaded saliently on items assessing prayer, meditation, seeking higher guidance during crisis, reading religious/spiritual literature, belief in afterlife, and existential dialogue (loadings generally ranging between .45 and .82).
2. Factor 2: Physical Well-Being: Characterized by robust loadings on items evaluating common functional complaints (headaches, nausea/vomiting, indigestion, bowel irregularities) and autonomic/energy indices (morning freshness, peripheral warmth, lethargy).
3. Factor 3: Mental Well-Being: Marked by positive loadings on intellectual pursuits, viewing quiz shows and documentaries, reading fiction, strategic games, and intentional environmental modification.

Subsequent psychometric examinations, notably by Green (2006) in social work research settings, utilized Confirmatory Factor Analysis (CFA) to evaluate whether a three-factor correlated model demonstrated superior goodness-of-fit compared to alternative unifactorial (general well-being) or orthogonal specifications. The three-factor correlated model displayed adequate to strong model fit indices (e.g., Comparative Fit Index $[CFI] > .90$; Root Mean Square Error of Approximation $[RMSEA] le .06$; Standardized Root Mean Square Residual $[SRMR] le .07$), validating the structural tenet that while mental, physical, and spiritual wellness are interrelated components of overall human flourishing, they represent distinct latent dimensions requiring discrete scoring and interpretation.

Instrument / Measurement Tool

The operational administration parameters of the MPSWS are summarized below:

• Instrument Name: Mental, Physical, and Spiritual Well-Being Scale (MPSWS / MPS Well-Being Scale)
• Developer: Dianne A. Vella-Brodrick & Felicity C. Allen (1995)
• Instrument Type: Multidimensional self-report psychological rating scale / survey
• Number of Items: 30 items
• Target Population: Adults and adolescents aged 16 and older; applicable in general community, academic, workplace, and clinical outpatient contexts.
• Administration Format: Paper-and-pencil or computer-assisted / interactive web-based questionnaire; self-administered.
• Completion Time: Approximately 8 to 12 minutes.
• Response Continuum:
  • Standard items utilize a 5-point Likert scale anchored by 1 = Often and 5 = Never (with intermediate gradations representing frequent to rare engagement).
  • Item 18 employs an item-specific longitudinal response format: 1 = “I have not”, 3 = “<5yrs” (less than five years), 5 = “>10yrs” (greater than ten years).
• Reverse Scoring: Items marked with an asterisk (*) in the formal scoring protocol (specifically items 3, 7, 8, 11, 12, 14, 15, 16, 17, 21, 22, 23, 25, 27, 28) require reverse scoring prior to subscale summation or directional metric transformation so that higher final numerical scores consistently designate greater positive well-being and lower somatic distress.
• Subscale Allocation:
  • Mental Well-Being Subscale: Items 2, 3, 4, 7, 9, 13, 14, 17, 19, 23, 26, 27.
  • Physical Well-Being Subscale: Items 5, 8, 10, 12, 15, 20, 21, 25, 28, 29.
  • Spiritual Well-Being Subscale: Items 1, 6, 11, 16, 18, 22, 24, 30.
• Scoring and Interpretation: Subscale raw scores are computed by summing the numerical responses across relevant subscale items following appropriate reverse coding. Standardized z-scores or percentage-of-maximum possible (POMP) scores may also be calculated for inter-domain comparisons. Clinically, profiling subscale scores permits detection of selective domain vulnerabilities (e.g., low physical vitality despite elevated mental or spiritual engagement).
