About Psychscale
The Psychology Scale Reference is a comprehensive guide to standardized psychological assessment instruments used in clinical practice, research, and education. It covers 27 validated scales across six domains: personality tests (MBTI 16-type classification, Big Five NEO-PI-R 240-item model, MMPI-2 567-item clinical assessment, TCI 7-factor model, Enneagram 9-type system), intelligence tests (WAIS-IV, K-WISC-V, Raven Progressive Matrices, Stanford-Binet 5), and clinical measures.
The reference includes complete scoring criteria and cutoff points for depression scales (BDI-II: 0-13 minimal to 29-63 severe; PHQ-9: 0-4 normal to 20-27 severe; HAM-D clinician-rated 17-item; CES-D community screening), anxiety inventories (BAI somatic/cognitive; GAD-7 generalized anxiety; STAI state-trait distinction; LSAS social anxiety with fear and avoidance subscales), motivation measures (AMS 7-subscale model, SRQ autonomy index, Grit Scale), and relationship scales (ECR-R attachment types, DAS marital adjustment, IRI empathy).
Designed for clinical psychologists, counselors, psychiatrists, psychology students, and researchers, this reference provides instant access to scale descriptions, scoring thresholds, and clinical interpretation guidelines in your browser.

Frequently Asked Questions
What personality scales are included in this reference?
This reference covers five major personality assessment tools: MBTI (Myers-Briggs Type Indicator) with its 4-dimension, 16-type classification system; Big Five NEO-PI-R measuring Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism across 240 items; MMPI-2 with 567 items and 10 clinical scales; Cloninger TCI with 4 temperament and 3 character factors; and the Enneagram 9-type system with wings and integration/disintegration directions.
How do I interpret BDI-II depression scores?
The Beck Depression Inventory-II (BDI-II) uses 21 items to assess depression severity over the past 2 weeks. Scoring ranges are: 0-13 (minimal depression), 14-19 (mild depression), 20-28 (moderate depression), and 29-63 (severe depression). The BDI-II is a self-report measure, so results should be considered alongside clinical interview findings.
What is the difference between WAIS-IV and K-WISC-V?
WAIS-IV (Wechsler Adult Intelligence Scale) is designed for adults and produces a Full-Scale IQ from 4 indices: Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed (mean 100, SD 15). K-WISC-V is the Korean adaptation of the Wechsler Intelligence Scale for Children (ages 6-16) with 5 indices adding Visual Spatial and Fluid Reasoning. Both are used for gifted identification and learning disability diagnosis.
How does the PHQ-9 differ from the BDI-II for depression screening?
The PHQ-9 (Patient Health Questionnaire-9) is a brief 9-item screening tool with cutoffs at 5/10/15/20 for mild/moderate/moderately-severe/severe depression. The BDI-II is a more detailed 21-item self-report measure. PHQ-9 is preferred for primary care screening due to its brevity, while BDI-II provides more granular assessment in clinical psychology settings.
What anxiety scales are covered and how do their scoring ranges differ?
Four anxiety scales are covered: BAI (Beck Anxiety Inventory, 21 items, 0-7 minimal to 26-63 severe, measuring somatic and cognitive anxiety), GAD-7 (7 items, 0-4 minimal to 15-21 severe, 2-week frequency), STAI (State-Trait Anxiety Inventory, 20 items each for state and trait anxiety, 20-80 range, 52+ clinically significant), and LSAS (Liebowitz Social Anxiety Scale, 24 items measuring fear and avoidance separately, 0-144 total, 55+ moderate).
What motivation scales are included and what do they measure?
Five motivation scales are covered: AMS (Academic Motivation Scale) with 7 subscales measuring intrinsic motivation (to know, accomplish, experience stimulation), extrinsic motivation (identified, introjected, external regulation), and amotivation; SRQ (Self-Regulation Questionnaire) calculating an autonomy index; IMI (Intrinsic Motivation Inventory) with 6 subscales; WPI (Work Preference Inventory) for occupational motivation; and the Grit Scale measuring passion consistency and perseverance of effort.
How does the ECR-R classify adult attachment types?
The ECR-R (Experiences in Close Relationships-Revised) uses 36 items to measure two dimensions: attachment anxiety and attachment avoidance. These dimensions classify individuals into four attachment types: Secure (low anxiety, low avoidance), Preoccupied (high anxiety, low avoidance), Dismissing (low anxiety, high avoidance), and Fearful (high anxiety, high avoidance).
What is the clinical cutoff for the DAS marital adjustment scale?
The Dyadic Adjustment Scale (DAS) uses 32 items across four subscales: Consensus, Satisfaction, Cohesion, and Affectional Expression. The total score ranges from 0-151, with scores below 107 suggesting marital maladjustment. The DAS is widely used in couples therapy to assess relationship quality and track therapeutic progress.
