3.3 Mental Health, Psychosocial & Ergonomic Assessments

Mental Health, Psychosocial & Ergonomic Assessments

Occupational therapy in mental health and industrial rehabilitation focuses on the dynamic interaction between psychological well-being, volitional drive, physical work capacity, and ergonomic environmental demands. Standardized psychosocial batteries and functional work assessments provide objective data for behavioral health interventions, disability determinations, and safe return-to-work programs.

1. Psychosocial & Psychiatric Evaluations

Psychosocial evaluations assess occupational engagement, interpersonal skills, behavioral self-regulation, motivation, and affective symptoms.

Comprehensive Occupational Therapy Evaluation Scale (COTE)

The COTE Scale is a standardized 25-item behavioral rating scale used extensively in adult inpatient and outpatient psychiatric settings, group therapy, and rehabilitation.

• Three Behavioral Categories:
  1. General Behaviors (7 items): Appearance, punctuality, activity level, non-productive behavior, response to structure, responsibility, orientation.
  2. Interpersonal Behaviors (6 items): Socialization, cooperativeness, assertiveness, group interaction, attention-getting behavior, hostility.
  3. Task Behaviors (12 items): Engagement, concentration, following directions, problem solving, neatness, attention to detail, organization, frustration tolerance, decision-making.
• Scoring System: Each item is scored on a 0 (normal / adaptive behavior) to 4 (severe impairment / disruption) scale. Serial administrations measure clinical progress and response to psychiatric medication or behavioral interventions.

Model of Human Occupation (MOHO) Psychosocial Batteries

• Assessment of Communication and Interaction Skills (ACIS): Observational tool evaluating 20 skills across Physicality (contact, gaze, posture, gesture), Information Exchange (fluency, assertion, questioning, disclosing, sharing), and Relations (collaborating, engaging, acknowledging, respecting).
• Volitional Questionnaire (VQ) & Pediatric VQ (PVQ): Evaluates inner drive and motivation to engage in occupations across four developmental continuum stages:
  1. Passive: Requires maximum environmental structure, encouragement, and physical assistance to initiate action.
  2. Hesitant: Shows interest and initiates with familiar tasks and supportive cues.
  3. Involved: Actively engaged, explores tasks with intrinsic interest and minimal assistance.
  4. Spontaneous: Independently seeks new challenges, highly self-directed and intrinsically motivated.
• Worker Role Interview (WRI): Semi-structured psychosocial interview evaluating how personal causation, values, habits, roles, and environmental perceptions affect return-to-work potential for injured or disabled workers.

Beck Depression Inventory-II (BDI-II)

• 21-item self-report questionnaire assessing the severity of depressive symptoms over the preceding 2 weeks.
• Standardized Cutoff Scores: 0–13: Minimal depression; 14–19: Mild depression; 20–28: Moderate depression; 29–63: Severe depression.
• CRITICAL CLINICAL SAFETY FLAG (Item 9): Item 9 specifically assesses suicidal ideation. Any score ≥ 1 on Item 9 (or any verbal endorsement of self-harm/suicide) mandates immediate, non-negotiable activation of the facility's suicide protocol, continuous visual observation, and emergency psychiatric notification.

Functional Capacity Evaluation (FCE)

An FCE is a comprehensive, standardized battery of physical and functional tests measuring an individual's safe physical capacity for work compared against the required physical demands of a specific job or general occupational classification.

• Core Components Evaluated:
  • Musculoskeletal exam (ROM, strength, postural stability)
  • Dynamic material handling (lifting, carrying, pushing, pulling)
  • Positional tolerances (sitting, standing, walking, kneeling, stooping, crouching, crawling, overhead reaching)
  • Cardiovascular and physical endurance
• Sincerity of Effort / Submaximal Effort Validation:
  1. Jamar Dynamometer 5-Rung Grip Test: Testing grip strength across all 5 handle positions. A sincere, maximal effort produces a characteristic bell-shaped (inverted U) curve (strongest at rungs 2 and 3). A flat line across all rungs indicates submaximal or insincere effort.
  2. Coefficient of Variation (CV): Standard deviation divided by the mean across 3 to 5 trials. A CV < 15% indicates consistent, maximal, sincere effort; a CV > 15% indicates inconsistent, submaximal effort.

Dictionary of Occupational Titles (DOT) Physical Demand Levels

Occupational therapists use the U.S. Department of Labor DOT physical demand classifications to quantify lifting requirements and match worker capacity to job demands:

Ergonomic Assessment Tools: RULA & REBA

• Rapid Upper Limb Assessment (RULA): Evaluates biomechanical and postural loading on the neck, trunk, and upper extremities in sedentary/seated tasks (e.g., computer workstations, light assembly).
  • Action Levels: Score 1–2 (Acceptable); Score 3–4 (Further investigation needed); Score 5–6 (Investigation and prompt changes required); Score 7 (Immediate redesign and changes required).
• Rapid Entire Body Assessment (REBA): Evaluates whole-body postures (legs, trunk, neck, upper/lower arms, wrists) and coupling grip quality during dynamic, multi-postural tasks (e.g., healthcare patient transfers, warehousing, construction).
  • Action Levels: Score 1 (Negligible risk); Score 2–3 (Low risk); Score 4–7 (Medium risk); Score 8–10 (High risk); Score 11–15 (Very high risk; implement changes immediately).

3. Pain Assessment Batteries

• Brief Pain Inventory (BPI): Measures pain intensity (0–10 scale) and pain interference across 7 daily functional domains: general activity, mood, walking ability, normal work, relationships with others, sleep, and enjoyment of life.
• McGill Pain Questionnaire (MPQ): Multidimensional pain questionnaire evaluating sensory, affective, and evaluative pain qualities using 78 pain descriptor words and a Present Pain Intensity (PPI) scale.
• Visual Analog Scale (VAS) & Numeric Rating Scale (NRS): Unidimensional pain intensity metrics (0–10 numeric or 100 mm line).
