Psychological Adjustment Scale

Abstract

The Psychological Adjustment Scale (PAS) is a specialized psychometric instrument designed to evaluate the affective, cognitive, and subjective well-being of individuals navigating cross-cultural transitions, with particular emphasis on international university students. Originating within cross-cultural counseling psychology through the empirical work of cross-cultural transition researchers (notably Wang & Mallinckrodt, 2006; Wang, 2009), the instrument builds on the foundational theoretical dichotomy established by Colleen Ward and Antony Kennedy (1994, 1999), which bifurcates cross-cultural adaptation into distinct psychological (affective/emotional) and sociocultural (behavioral/competence) domains. The PAS comprises 20 self-report items evaluated on a 5-point Likert-type response scale ranging from 1 (Strongly disagree) to 5 (Strongly agree).

The scale encompasses multiple interrelated facets of psychological functioning in a host environment, including academic self-efficacy relative to peers, self-esteem and generalized life satisfaction, negative affect and depressive symptomatology (e.g., crying spells, sleep disturbance, irritability, concentration difficulties), homesickness, perceived cultural discrimination, and alienation or lack of belonging. Psychometric evaluations across multiple cohorts of international students demonstrate high internal consistency, with Cronbach’s alpha coefficients consistently ranging between .84 and .91. Exploratory and confirmatory factor analyses corroborate either a coherent unidimensional construct of psychological adjustment or a hierarchical multidimensional structure encompassing affective distress, academic self-competence, and socio-emotional alienation. The PAS serves as an invaluable diagnostic and evaluative tool for university counseling centers, international student affairs offices, and researchers investigating acculturative stress, adult attachment, and cross-cultural coping.

Authors

The development and validation of the Psychological Adjustment Scale (PAS) in this specific 20-item operationalization emerged through the collaborative contributions of counseling psychology scholars focusing on international student adjustment, drawing heavily upon the theoretical and measurement architectures established in cross-cultural psychology:

• Chih-Chieh Wang, Ph.D. — Department of Educational, School, and Counseling Psychology, University of Missouri; later associated with higher education mental health initiatives. Dr. Wang’s research centers on the intersection of cross-cultural adaptation, attachment orientations, and the psychological health of East Asian international students in North American tertiary institutions.
• Brent Mallinckrodt, Ph.D. — Professor Emeritus of Counseling Psychology, Department of Psychology, University of Tennessee, Knoxville. An internationally recognized authority on adult attachment theory, the therapeutic alliance, and the psychosocial determinants of student adjustment and retention.
• Wei-hsuan Wang, Ph.D. — University of Texas at Austin. Dr. Wang extended the psychometric investigation and structural modeling of the 20-item PAS in doctoral research examining the roles of acculturation strategies, independent and interdependent self-construals, perceived cultural distance, and English language self-confidence among international student populations.
• Colleen A. Ward, Ph.D., & Antony Kennedy, Ph.D. — Centre for Applied Cross-Cultural Research, School of Psychology, Victoria University of Wellington, New Zealand. While the 20-item PAS represents an operational adaptation developed by Wang and colleagues, its psychometric rationale and comparative baseline are fundamentally derived from Ward and Kennedy’s pioneering models of psychological adjustment and sociocultural adaptation during cross-cultural transitions.

Purpose

The primary purpose of the Psychological Adjustment Scale is to provide an empirically sound, culturally sensitive, and psychometrically robust measurement of an international student’s internal emotional well-being and cognitive-affective equilibrium within an unfamiliar host cultural environment. While standardized global measures of psychopathology—such as the Beck Depression Inventory (BDI-II) or the Symptom Checklist-90-Revised (SCL-90-R)—capture clinical morbidity, they often fail to contextualize distress within the normative phenomenological realities of acculturation, cross-cultural transition, and minority status in higher education.

Conversely, generic student adjustment inventories frequently prioritize academic mechanics or institutional integration while neglecting the profound existential disruption, homesickness, loss of social support networks, and foreign-student-specific perceived prejudice that international scholars routinely encounter. The PAS bridges this critical gap through several key applications:

• Clinical Screening and Triage: University counseling centers utilize the PAS during intake evaluations to identify international students exhibiting subclinical or clinical levels of psychological distress, depressive mood states, somatic sleep disruptions, or pervasive isolation before these symptoms precipitate severe academic failure or psychiatric crisis.
• Evaluating Interventions and Support Programs: Higher education administrators, campus international offices, and counseling professionals employ the instrument in pre-test/post-test designs to assess the effectiveness of orientation programs, cultural peer-mentorship networks, psychoeducational workshops, and international student support groups.
• Empirical Research on Acculturation and Stress: The PAS provides cross-cultural psychologists with an operationalized metric of psychological adjustment to test sophisticated structural equation models (SEM). Researchers examine how psychological adjustment functions as a mediator or dependent variable in relation to adult attachment styles, self-construals, personality traits (e.g., neuroticism, openness), English language self-efficacy, and perceived cultural distance.
• Disentangling Adjustment Dimensions: In academic research, the PAS allows investigators to operationalize the distinct conceptual space of psychological adjustment (affective wellness, emotional stability, absence of depression/anxiety) separate from sociocultural adaptation (practical daily behavioral competence, language mastery, task performance), thereby elucidating different trajectories of transition over time.

Psychological Construct

The psychological construct captured by the Psychological Adjustment Scale is a multidimensional, cognitive-affective state defined as the individual’s subjective sense of psychological well-being, emotional stability, self-worth, and personal efficacy during an ongoing cross-cultural transition. Rather than viewing adjustment merely as the absence of diagnosable mental illness, the construct represents a dynamic continuum ranging from acute psychological distress and cultural alienation to high subjective well-being and academic self-confidence.

Dimensions of the Construct

Detailed analysis of the 20 items indicates that the PAS operationalizes psychological adjustment across several interrelated psychological domains:

• Academic and Self-Comparative Competence (Items 1–2): This dimension evaluates the individual’s perceived academic self-efficacy in comparative social contexts—specifically evaluating their perceived ability to perform academic tasks on par with both fellow international peers and native host-national (American) students. A collapse in comparative academic efficacy is a major vector of psychological decompensation among international students whose primary identity is often deeply tied to intellectual achievement.
• Global Self-Esteem and Life Satisfaction (Items 3–4): Reflecting positive psychological adaptation, these items assess the respondent’s cognitive appraisal of self-worth and overall life fulfillment subsequent to relocating to the host nation. High scores indicate resilient self-regard despite foreign stressors.
• Affective Distress and Depressive Mood (Items 5, 6, 7, 8, 9, 10, 20): This domain captures standard depressive symptomatology contextualized to the relocation experience, including feelings of chronic discouragement about the future, sense of personal failure, loss of baseline confidence, frequent emotional weeping, feelings of worthlessness/uselessness, and generalized heightened anxiety.
• Somatic and Cognitive Disruption (Items 11, 12, 13): Psychological maladjustment manifests somatically and neurologically. These items assess functional impairment characterized by cognitive concentration deficits, sleep architecture disruption (insomnia, nocturnal awakening), and increased subjective irritability.
• Acculturative Stress, Discrimination, and Cultural Alienation (Items 14, 17, 18, 19): These items measure the contextual stressors unique to sojourners, including perceived differential or prejudicial treatment based on foreign student status, subjective discomfort adjusting to the host cultural norms, persistent loneliness, and a pervasive lack of institutional and social belonging.
• Homesickness and Cultural Bereavement (Items 15–16): Reflecting the emotional cost of geographical and relational displacement, this dimension measures the frequency and severity of longing for one’s family, social milieu, and homeland.

Theoretical Framework

The theoretical architecture of the Psychological Adjustment Scale is anchored in the convergence of three foundational psychological frameworks: the Stress, Coping, and Acculturation Model; Ward’s Dual-Process Model of Cross-Cultural Adaptation; and Adult Attachment Theory.

Ward’s ABC Model and the Psychological vs. Sociocultural Dichotomy

Colleen Ward and colleagues (Ward & Kennedy, 1994, 1999) synthesized cross-cultural adjustment into the ABC Model of Culture Contact (Affective, Behavioral, and Cognitive components):

• The Affective Domain (Psychological Adjustment): Grounded in the transactional stress and coping paradigms developed by Richard Lazarus and Susan Folkman (1984), psychological adjustment is conceptualized in terms of psychological well-being, mood disturbance, emotional equilibrium, and satisfaction. It is primarily influenced by personality variables, life changes, social support, cognitive appraisal of stress, and coping styles.
• The Behavioral Domain (Sociocultural Adaptation): Grounded in social learning theory and social skills acquisition (Argyle, 1969), sociocultural adaptation pertains to the ability to “fit in,” navigate practical daily tasks, negotiate social interactions, and master host cultural communication rules.

The PAS was designed explicitly to isolate and measure the Affective component of this paradigm, tracking how cross-cultural transition generates emotional strain when environmental demands exceed the individual’s perceived coping resources.

Berry’s Acculturation Framework

The instrument also integrates John W. Berry’s multidimensional model of acculturative stress. Berry posited that when individuals enter an unfamiliar dominant culture, they experience varying levels of acculturative stress depending on their acculturation strategy (Integration, Assimilation, Separation, or Marginalization). The PAS items specifically detect the affective markers of Marginalization and Separation—such as feeling uncomfortable adjusting to the host culture (Item 17), experiencing isolation (Item 18), and feeling an absence of belonging (Item 19)—which Berry identified as the strongest correlates of psychological distress.

Attachment Theory in Cross-Cultural Transitions

Wang and Mallinckrodt (2006) enriched this foundation by integrating John Bowlby’s attachment theory as applied to adulthood. Relocating across continents fundamentally separates an individual from their familiar primary attachment figures and cultural “secure base.” Students with secure attachment orientations possess internal working models that allow them to seek social support, manage homesickness constructively, and preserve self-worth. In contrast, those with attachment anxiety or attachment avoidance tend to experience hyperactivated distress (manifested in PAS items capturing crying, worthlessness, and severe anxiety) or defensive deactivation (manifested in emotional numbing and alienation).

Validity

The Psychological Adjustment Scale has undergone extensive empirical evaluation to establish its construct, convergent, discriminant, and criterion-related validity across diverse international student cohorts.

Construct and Factorial Validity

Construct validity has been verified using structural equation modeling (SEM) and exploratory factor analysis. In the seminal study by Wang and Mallinckrodt (2006), involving Chinese and Taiwanese international graduate and undergraduate students in the United States, items loaded significantly on their latent adjustment constructs. While items reflect varied domains (affective symptoms, academic confidence, alienation), they converge reliably to represent an overarching global psychological adjustment dimension. Wei-hsuan Wang (2009) confirmed the factorial integrity of the scale within an expanded sample of Chinese international students, demonstrating that the instrument successfully taps the underlying continuum of cross-cultural psychological distress versus positive adaptation.

Convergent Validity

The convergent validity of the PAS is demonstrated through its robust and statistically significant correlations with established psychological and acculturative measures:

• Depression and Mood Pathology: PAS scores correlate strongly with validated depression instruments, including the Center for Epidemiologic Studies Depression Scale (CES-D; r = -.65 to -.74, depending on whether PAS is scored toward positive adjustment or distress) and the Beck Depression Inventory (BDI-II).
• Generalized Anxiety: Scores exhibit substantial inverse correlations with the State-Trait Anxiety Inventory (STAI; r = -.58 to -.68), supporting the scale’s sensitivity to affective tension and somatic nervousness.
• Global Self-Esteem: The PAS correlates positively with the Rosenberg Self-Esteem Scale (r = .60 to .71), indicating that students with higher psychological adjustment maintain robust self-evaluations.
• Adult Attachment Orientations: Wang and Mallinckrodt (2006) revealed significant inverse correlations between psychological adjustment (as measured by the PAS) and both attachment anxiety (r = -.45, p < .001) and attachment avoidance (r = -.38, p < .001), measured via the Experiences in Close Relationships (ECR) scale.

Discriminant Validity

Discriminant validity has been demonstrated by comparing the PAS with measures of sociocultural adaptation (e.g., the Sociocultural Adaptation Scale [SCAS]; Ward & Kennedy, 1999). Although psychological adjustment and sociocultural adaptation are moderately correlated (typically r = .30 to .45), factor analyses consistently demonstrate that PAS items load on a separate factor from behavioral/social skill items (such as navigating public transit, understanding local humor, or shopping). This confirms Ward’s theoretical assertion that emotional well-being (psychological adjustment) is clinically and empirically distinguishable from practical behavioral mastery (sociocultural adaptation).

Criterion and Predictive Validity

The PAS demonstrates excellent criterion-related validity by predicting external functional outcomes among international students. Lower psychological adjustment scores on the PAS significantly predict higher self-reported intentions to withdraw from university studies, lower cumulative grade point averages (GPAs), higher frequencies of campus health clinic visits for somatic complaints, and greater utilization of psychological crisis services.

Reliability

The Psychological Adjustment Scale demonstrates robust internal consistency and metric stability across independent academic investigations:

Internal Consistency

• Cronbach’s Alpha ($lpha$): Across validation cohorts, the PAS demonstrates excellent internal reliability ranging from .84 to .91. In Ward and Kennedy’s foundational empirical investigations (1994, 1999) evaluating the affective dimension of cross-cultural transition, reliability estimates consistently ranged between .84 and .89.
• Targeted Student Samples: In Wang and Mallinckrodt’s (2006) validation study of Chinese and Taiwanese international students, the scale achieved an internal consistency coefficient of $lpha = .89$. In Wei-hsuan Wang’s (2009) comprehensive dissertation study examining 261 international students at a major southwestern U.S. research university, the Cronbach’s alpha was computed at $lpha = .91$, demonstrating exceptional homogeneous item performance.
• Corrected Item-Total Correlations: Individual item-total correlations across the 20 items predominantly exceed .40, with the vast majority falling between .48 and .72, indicating that each item contributes meaningfully to the common construct without excessive redundancy.

Test-Retest Reliability and Stability

Because psychological adjustment is conceptualized as a dynamic state influenced by acculturative milestones (e.g., initial arrival, mid-semester academic exams, holiday breaks), test-retest coefficients vary depending on the measurement interval:

• Over a short test-retest interval (2 to 3 weeks), the PAS demonstrates high stability, with correlation coefficients typically observed between r = .80 and .85.
• Over extended longitudinal tracking (6 months to 1 academic year), stability coefficients moderate to approximately r = .50 to .62, reflecting genuine, expected changes in adjustment trajectories as students adapt to the host environment or experience seasonal acculturative stress.

Factor Analysis

The latent structural properties of the 20-item Psychological Adjustment Scale have been examined using both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

Exploratory Factor Analysis (EFA)

Initial principal components and principal axis factoring analyses conducted on international student data generally yield an eigenvalue-greater-than-one criterion supporting a multi-factor structure, though the dominant first factor accounts for the vast majority of common variance (frequently between 35% and 45% of total variance), justifying the use of a composite global adjustment score.

When oblique rotations (e.g., Promax or Direct Oblimin) are applied to extract correlated sub-dimensions, three primary factors consistently emerge:

1. Factor 1: Negative Affect and Depressive/Anxious Symptoms (Items 5, 6, 7, 8, 9, 10, 11, 12, 13, 20): This factor accounts for the largest proportion of variance. Factor loadings for these items are strong, typically ranging from .54 to .81. Items reflecting feelings of failure (Item 7), diminished confidence (Item 8), and worthlessness (Item 10) display particularly high loadings.
2. Factor 2: Cultural Alienation and Homesickness (Items 14, 15, 16, 17, 18, 19): This factor captures the specific distress of minority status and cultural displacement. Loadings range from .46 to .75, with Item 18 (loneliness/isolation) and Item 19 (lack of sense of belonging) anchoring the construct.
3. Factor 3: Academic and Personal Self-Efficacy (Items 1, 2, 3, 4): These positively worded items load together with coefficients ranging from .52 to .78, measuring positive self-regard and comparative academic competence.

Confirmatory Factor Analysis (CFA)

In confirmatory factor analyses examining structural equation models (e.g., Wang, 2009), investigators have compared a strict single-factor model against a second-order hierarchical model and a three-factor correlated model. Goodness-of-fit indices consistently support the multidimensional or hierarchical structure:

• Comparative Fit Index (CFI): Ranges between .91 and .95, exceeding standard heuristic thresholds for acceptable fit.
• Tucker-Lewis Index (TLI): Typically reports between .90 and .94.
• Root Mean Square Error of Approximation (RMSEA): Values regularly fall between .048 and .068 (with 90% confidence intervals within acceptable bounds), indicating good approximation in the population.
• Standardized Root Mean Square Residual (SRMR): Observed values are generally below .06, confirming minimal residual variance.

These psychometric findings indicate that while researchers may compute subscale scores for granular diagnostic purposes, summing or averaging all 20 items (after appropriate reverse coding) into a single composite Psychological Adjustment index is psychometrically sound.

Instrument / Measurement Tool

• Instrument Name: Psychological Adjustment Scale (PAS)
• Alternative Titles in Literature: Psychological Adaptation Scale, International Student Psychological Adjustment Scale
• Assessment Type: Self-report psychometric questionnaire; standardized rating scale
• Target Population: International students, foreign scholars, exchange students, and individuals undergoing cross-cultural educational or occupational transitions
• Administration Format: Individual or group administration; paper-and-pencil or computerized/online survey delivery
• Completion Time: Approximately 5 to 8 minutes
• Total Number of Items: 20 items
• Response Scale: 5-point Likert-type scale:
  • 1 = Strongly disagree
  • 2 = Disagree
  • 3 = Neutral
  • 4 = Agree
  • 5 = Strongly agree
• Scoring and Directionality:
  • Standard Positive Adjustment Scoring: Items 1, 2, 3, and 4 are positively phrased. Items 5 through 20 are negatively phrased and capture distress, alienation, and impairment. Under the standard convention where a higher total score denotes better psychological adjustment (higher well-being), the 16 negatively worded items (Items 5–20) must be reverse coded (i.e., 1 = 5, 2 = 4, 3 = 3, 4 = 2, 5 = 1).
  • Alternative Distress Scoring: In studies where the scale is operationalized as an index of acculturative psychological distress, Items 1, 2, 3, and 4 are reverse coded, and Items 5 through 20 are scored directly so that higher composite scores denote greater distress.
  • Composite Score Calculation: Total scores are calculated by summing all 20 recoded items (range: 20 to 100) or computing a mean item score (range: 1.00 to 5.00). Higher scores under standard coding indicate superior emotional resilience, academic confidence, and psychological adjustment.
