1. Abstract
The Social Adjustment Scale (SAS), developed by Stanley P. Zarlock in 1961 at the University of Buffalo, is a specialized psychometric clinician- and caseworker-administered rating instrument constructed to measure the objective social adaptability and functional rehabilitation outcomes of blind adults. Formulated within the context of an empirical investigation into the relationship between magical thinking, ego defenses, and overt behavioral coping following severe sensory deprivation, the scale operationalizes social maturity through behavioral mastery across six essential life domains: Employment, Travel, Family Adjustment, Social Relationships, Leisure Time Activities, and Self-Care and Personal Management. Diverging from purely intrapsychic or subjective self-report inventories, the Social Adjustment Scale deliberately excludes covert psychological reactions and internalized affect, focusing instead upon manifest, observable problem-solving behaviors, environmental competence, and community integration.
Each of the six functional areas is evaluated on a standardized 0-to-5 metric yielding a composite social adjustment score ranging from 0 to 30, where elevated values represent superior functional independence, successful environmental mastery, and adaptive social maturity. Methodologically, the scale leverages a dual-rater consensus paradigm combining comprehensive observational evaluations by clinical investigators with longitudinal behavioral assessments conducted by qualified social caseworkers. The initial psychometric validation demonstrated exceptional inter-rater reliability, yielding an observed correlation coefficient of r = .92 between caseworkers and independent clinical evaluators, which rose to a corrected reliability coefficient of .95 upon application of the Spearman-Brown prophecy formula for composite scoring. By demonstrating robust negative correlations with archaic magical beliefs and infantile defense mechanisms, the scale established seminal construct validity within rehabilitation psychology, affirming that realistic environmental adaptation serves as an inverse correlate of psychological regression among adults experiencing severe visual impairment.

3. Authors
The Social Adjustment Scale was conceived, developed, and empirically validated by Stanley P. Zarlock, Ph.D. During the inception and publication of the instrument in 1961, Dr. Zarlock was affiliated with the Department of Psychology at the University of Buffalo (subsequently reorganized into the State University of New York at Buffalo) in Buffalo, New York, United States. Dr. Zarlock’s mid-twentieth-century research program bridged the interfaces of clinical psychology, somatopsychology, and physical rehabilitation, with a primary empirical focus on the psychodynamics of sensory deprivation, ego adaptation, and the socio-behavioral sequelae of adventitious and congenital blindness.
In developing the instrument, Dr. Zarlock collaborated extensively with professional rehabilitation specialists, field caseworkers, and institutional social service departments dedicated to the welfare of blind adults. The theoretical and psychometric framework for the scale was established within his clinical investigations exploring the coexistence of primitive psychological defenses—specifically magical ideation and omnipotent fantasies—alongside realistic behavioral competencies in individuals adapting to severe visual loss.
4. Purpose
The primary purpose of the Social Adjustment Scale is to provide an objective, standardized, and clinically rigorous assessment of overt social adaptability and community functioning among visually impaired and totally blind adults. In the post-World War II era, clinical evaluations of individuals with visual disabilities were frequently confounded by subjective patient reporting, intrapsychic diagnostic ambiguity, or an over-reliance on purely ophthalmological metrics that bore little direct correspondence to everyday community navigation, vocational competence, or personal autonomy. Zarlock designed the scale to fulfill four interrelated empirical and clinical objectives:
- Objective Quantification of Behavioral Adaptation: The scale was established to operationalize social adjustment not as an internal affective state of contentment or resignation, but as a demonstrable constellation of problem-solving skills, social competencies, and self-directed behavioral repertoires across essential life situations.
- Dissociation of Behavioral Competence from Psychological Defenses: A foundational rationale was to evaluate whether external, overt behavioral competence could coexist with, or conversely serve as an antidote to, primitive intrapsychic phenomena such as magical thinking, wish-fulfillment fantasies, and psychological regression following severe vision loss.
- Standardized Multidisciplinary Evaluation: The instrument facilitates an integrative clinical consensus by combining the clinical observations of psychological investigators with the ecological, long-term case records maintained by rehabilitation caseworkers, thereby mitigating single-observer bias.
- Rehabilitation Program Planning and Outcome Monitoring: By systematically diagnosing performance deficits across discrete domains (e.g., orientation and mobility vs. personal management vs. family functioning), the instrument provides multidisciplinary rehabilitation teams with clear diagnostic baselines to customize vocational training, orientation instruction, and independent living interventions.
In contemporary and historical rehabilitation contexts, the tool serves both diagnostic and evaluative functions. In clinical rehabilitation settings, it enables practitioners to distinguish between individuals experiencing localized functional deficits (such as travel limitations amenable to cane travel training) and those exhibiting widespread socio-behavioral breakdown. In empirical research, the scale provides a quantifiable continuous index of ecological adjustment that can be correlated with personality profiles, cognitive styles, social support networks, and intervention methodologies across the continuum of visual impairment.
5. Psychological Construct
The psychological construct assessed by the instrument is Social Adjustment to Blindness. Within Zarlock’s psychometric model, social adjustment is defined as the capacity of a visually impaired individual to meet cultural, social, and functional environmental demands through autonomous, realistic, and socially mature behavioral problem-solving. Crucially, Zarlock deliberately restricted the construct definition to overt, observable behaviors and social maturity, intentionally excluding covert psychological states, internalized emotional distress, self-perceptions, or psychiatric symptomatology from the rating criteria. This conceptual demarcation ensured that the instrument measured real-world ecological efficacy rather than psychological distress or subjective self-esteem.
Dimensions of the Construct
The construct is operationalized across six distinct yet interrelated functional dimensions:
1. Employment (Vocational Adjustment)
This dimension evaluates the individual’s capacity to achieve and sustain economic self-sufficiency, vocational productivity, and stability within competitive, sheltered, or self-directed employment. In Zarlock’s validation criteria, an exemplar anchor included continuous, gainful employment for at least one year. This dimension reflects an individual’s persistence, cognitive adaptation, vocational skill acquisition, and capacity to function productively despite architectural, systemic, and perceptual barriers.
2. Travel (Mobility and Environmental Orientation)
Travel captures physical independence, spatial orientation, and autonomous mobility within the broader community. It assesses the proficiency with which an individual actively utilizes sensory aids—specifically the white cane or a guide dog—to negotiate unfamiliar public environments, utilize mass transit, and manage navigational hazards safely and independently without constant sighted escort.
3. Family Adjustment
This domain examines the individual’s interpersonal role functioning, reciprocity, and psychological independence within the primary domestic environment. It measures the extent to which the person maintains an equitable, mature role within the family constellation rather than succumbing to regressive infantilization, passive over-dependence, or dysfunctional family dynamics where the blind adult is treated as an invalid.
4. Social Relationships
Social relationships encompass the breadth, depth, and parity of the individual’s peer networks. It assesses the ability to initiate, cultivate, and sustain reciprocal friendships with both sighted and visually impaired peers. High adjustment in this dimension reflects active participation in broader societal circles, avoidance of social isolation, and the absence of defensive withdrawal or social hostility.
5. Leisure Time Activities
This dimension focuses on constructive engagement in recreational, cultural, intellectual, and civic pursuits during non-working hours. Behavioral anchors include active membership in civic organizations, community clubs, hobby groups, and cultural associations. It gauges whether the individual leads a dynamic, enriched life or retreats into passivity, boredom, and vegetative isolation.
6. Self-Care and Personal Management
Self-care assesses complete functional autonomy in the activities of daily living (ADLs). This encompasses the execution of personal grooming, hygiene, selecting and purchasing one’s own clothing, meal preparation, and maintaining normative social etiquette during communal dining. Mastery in this domain denotes the triumph of practical adaptive learning over functional helplessness.
6. Theoretical Framework
The Social Adjustment Scale is anchored in the mid-twentieth-century framework of Somatopsychology and psychoanalytically informed ego psychology, specifically synthesised by Zarlock to examine the psychological consequences of physical disability. Zarlock’s work emerged in dialogue with the foundational somatopsychological models articulated by Roger Barker, Beatrice Wright, and Tamara Dembo, who postulated that physical disability constitutes a profound ecological and social crisis requiring radical behavioral and perceptual reorganization.
The Dilemma of Somatopsychic Readjustment
According to somatopsychological theory, severe sensory loss radically alters the individual’s perceptual relationship to the physical and social environment. Visual impairment introduces profound barriers to locomotion, interpersonal communication, and daily autonomy, creating persistent threats to self-worth. In response to this existential disruption, the ego is confronted with two fundamental paths:
- Realistic Problem-Solving and Mastery: The mobilization of reality-oriented ego functions, deliberate skill acquisition (e.g., braille literacy, white cane mobility, tactile orientation), and progressive integration into normative social roles.
- Psychological Regression and Magical Thinking: The reactivation of archaic, infantile defense mechanisms characterized by omnipotent fantasies, wish-fulfillment beliefs regarding spontaneous biological restoration, and externalized attributions of causality.
Zarlock’s Formulation of Magical Ideation
Zarlock (1961) demonstrated particular interest in the psychoanalytic concept of magical thinking as conceptualized by Sigmund Freud and expanded by Sándor Ferenczi. Ferenczi posited that in early infancy, the psyche operates under beliefs of unconditioned omnipotence, where wishes are perceived as having immediate physical efficacy. Under severe traumatic stress or catastrophic sensory deprivation, adults may regress to this archaic ego stage, harboring secret convictions that their sight will miraculously return without medical intervention, or that external agents are magically responsible for their functional limitations.
Zarlock hypothesized that magical thinking serves as an immature defense against the painful reality of permanent blindness. Consequently, an individual who expends psychic energy on magical restoration is predicted to display severe deficits in overt problem-solving. Conversely, the individual who confronts the finality of sensory loss redirects psychic energy toward adaptive mastery. The Social Adjustment Scale was constructed precisely to measure the behavioral fruit of this reality adaptation: overt, measurable competence in the physical and social world.
7. Validity
The psychometric validation of the Social Adjustment Scale, as reported by Zarlock (1961), was conducted within a rigorous comparative research design investigating the psychological concomitants of visual disability among adults.
Construct and Criterion-Related Validity
Construct validity was primarily demonstrated through the systematic testing of theoretical hypotheses regarding the inverse relationship between magical thinking and adaptive behavioral functioning. Zarlock evaluated a cohort of blind adult subjects across comprehensive personality batteries, projective indices, and structured questionnaires assessing magical beliefs, while concurrently obtaining blind ratings on the Social Adjustment Scale from social caseworkers and psychological investigators.
The empirical findings revealed statistically significant negative correlations between scores on the Social Adjustment Scale and indices of magical thinking, infantile dependency, and primitive ego defenses. Specifically, individuals who scored high on social adjustment demonstrated an absence of supernatural or magical rationalizations regarding their blindness, exhibited realistic appraisals of their physical limitations, and engaged in active, planful problem-solving. Conversely, subjects with low social adjustment scores displayed pronounced elevations on measures of magical ideation, fatalistic passivity, and emotional withdrawal. These significant divergences provided robust evidence of construct validity, demonstrating that the scale accurately captures the presence of mature ego functioning and practical reality adaptation.
Content and Face Validity
The content validity of the instrument was grounded in an exhaustive review of existing blindness rehabilitation checklists, empirical literature on the sociology of disability, and direct consultations with professional caseworkers from specialized agencies for the blind. The six functional areas—Employment, Travel, Family Adjustment, Social Relationships, Leisure Activities, and Self-Care—were selected because they represent the core ecological demands imposed upon blind adults in community living. By formulating explicit behavioral benchmarks (e.g., “reads and writes braille,” “uses cane or dog guide to travel about the community,” “buys his own clothes”), the scale achieved high face validity and clinical relevance for both rehabilitation workers and research psychometricians.
8. Reliability
The reliability of the Social Adjustment Scale was evaluated primarily through the rigorous assessment of inter-rater agreement between two highly distinct observational perspectives: field social caseworkers possessing long-term longitudinal familiarity with the subjects, and independent clinical investigators conducting standardized experimental evaluations.
Inter-Rater Reliability Coefficients
In the primary empirical study (Zarlock, 1961), independent ratings were completed across all six behavioral areas for each participant. The raw correlation coefficient obtained between the independent caseworker ratings and the psychological investigator ratings was:
This high correlation demonstrated that despite operating from different vantage points (ecological casework records vs. clinical observational interviews), the behavioral anchors provided by the scale yielded remarkable consensus regarding the functional adaptability of the participants.
Spearman-Brown Prophecy Formulation
Because the clinical assessment protocol advocated combining the evaluations of both the social worker and the clinical investigator to form a pooled composite rating, Zarlock applied the Spearman-Brown Prophecy Formula to estimate the reliability of the combined composite scores. The application of this formula yielded an elevated reliability coefficient:
An internal consistency and composite reliability of .95 indicates that measurement error accounts for only 5% of the score variance when multiple raters contribute to the final assessment, satisfying the most stringent psychometric standards for both group-level research and individual diagnostic classification.
9. Factor Analysis
At the time of the scale’s construction and publication in 1961, formal statistical factor analysis—such as Exploratory Factor Analysis (EFA) or Confirmatory Factor Analysis (CFA) utilizing maximum likelihood estimation—was not universally applied to six-item clinical rating scales due to computational limitations and the deliberate clinical construction of the instrument as a composite index. Consequently, no empirical factor analysis was reported in Zarlock’s original monograph.
Subsequent Psychometric Considerations and Dimensionality
Although formally unanalyzed via latent variable modeling in 1961, the internal structural properties of the Social Adjustment Scale reflect a cohesive, unidimensional composite construct of functional community competence, supported by six discrete behavioral facets. In modern psychometric terminology:
- Formative vs. Reflective Conceptualization: The scale can be conceptualized psychometrically as a formative measurement model (or functional status index), where the six domains collectively define and construct the latent entity of “social adjustment,” rather than functioning merely as exchangeable reflective indicators. Under a formative perspective, an individual might exhibit high vocational stability while struggling with independent travel; each area contributes additive variance to overall ecological adaptation.
- Latent Trait Unidimensionality: Later analyses of functional status rating scales modeled after Zarlock’s taxonomy suggest that when evaluated via modern item response theory (IRT) or principal component analysis, functional adaptation to blindness predominantly loads onto a primary general factor (General Functional Independence) with secondary cluster loadings differentiating instrumental daily skills (Self-Care, Travel) from psychosocial integration (Family, Social Relationships, Leisure).
Modern investigators utilizing the instrument are advised to examine both the unidimensional composite score (0–30) and the disaggregated dimensional profile across the six specific areas to identify localized versus pervasive adaptive impairments.
