Model of Human Occupation Screening Tool
Also known as: MOHO-ST, MOHO Screening Tool
The Model of Human Occupation Screening Tool (MOHO-ST) is a brief, clinician-administered interview-based assessment grounded in the Model of Human Occupation (MOHO) theoretical framework. Developed by Parkinson, Forsyth, and Kielhofner (2006), the MOHO-ST screens for occupational participation and motivation across four key dimensions: volition (interests, values, personal causation), habituation (roles and routines), performance capacity, and environmental supports/barriers. The MOHO-ST is used in occupational therapy across mental health, physical rehabilitation, vocational rehabilitation, and community practice to quickly assess occupational functioning and identify areas for intervention.

When to use it
The MOHO-ST is appropriate for adults across occupational therapy practice settings: mental health (depression, anxiety, schizophrenia, bipolar disorder), physical rehabilitation (stroke, spinal cord injury, burn, multiple sclerosis), vocational rehabilitation and work-return, community integration post-incarceration or substance use recovery, aging and retirement planning, and geriatric care. The MOHO-ST is particularly valuable for quick occupational screening when a comprehensive occupational profile is needed but time is limited. It is suitable for both acute clinical settings and community-based practice. The MOHO-ST is less suitable for individuals with severe cognitive impairment, active psychosis, or communication disorders preventing reliable interview; however, clinical judgment and adaptation are possible.
Strengths & limitations
- Theoretically grounded: Based on MOHO framework, which aligns with core occupational therapy concepts of motivation, roles, capacity, and environment.
- Holistic occupational assessment: Addresses motivation (volition), organization (habituation), capability (performance), and context (environment) in integrated fashion.
- Clinician-interview format: Allows dialogue, clarification, and observation of client engagement, providing richer data than questionnaire alone.
- Quick screening: Typically 20–30 minutes; suitable for busy settings or initial assessment.
- Domain-specific analysis: Subscale scores identify particular occupational challenges (e.g., low motivation, poor routines, limited environmental support).
- Guides intervention planning: Domain profiles directly suggest intervention strategies (e.g., volition-focused therapy, habit-formation, capacity-building, environmental modification).
- Collaborative exploration: Interview process itself promotes client reflection on occupational life and engagement in assessment.
- Multiple language versions: Available in English, Spanish, and other languages; widely applicable across populations.
- Responsive to therapy: Changes in domain scores track occupational motivation and engagement improvements over time.
- Clinician-dependent: Requires trained occupational therapist to conduct and interpret; not suitable for self-administered or non-OT administration.
- Subjective rating: Clinician judgment in rating items introduces potential bias; reliability depends on clinician training and consistency.
- Interview-format limitations: Time-consuming compared to questionnaire; requires client to articulate experiences; non-verbal or very withdrawn clients may provide limited information.
- No objective performance measurement: Does not measure actual occupational performance; relies on client report and clinician observation.
- Limited normative data: No population-specific norms; interpretation relies on clinical judgment and qualitative analysis rather than norm-referenced comparison.
- Ordinal scaling: 4-point scale provides limited granularity; small changes between ratings may reflect rater variability rather than real change.
- Environment domain limitations: Clinician may have incomplete information about client's full occupational environment; self-report may not capture all barriers/supports.
- Discrepancy between domains: Client may demonstrate capacity but lack volition; the tool captures both, but clinical interpretation of discrepancies requires expertise.
Frequently asked
How is the MOHO-ST different from the Occupational Self-Assessment (OSA)?
Both are MOHO-based occupational therapy tools. The MOHO-ST is clinician-interview-based with 14 items rated by the clinician after discussion; the OSA is client self-rating with 21 items. MOHO-ST screens across all four MOHO domains; OSA focuses on client-perceived competence vs. importance of activities. MOHO-ST is briefer (~20–30 min); OSA takes 15–20 min. MOHO-ST is a screening tool; OSA is more detailed for goal-setting. Both can be used together.
Is the MOHO-ST suitable for clients with limited communication ability?
The MOHO-ST requires sufficient communication and self-awareness to discuss occupational life. Clients with severe aphasia, dementia, or profound psychiatric symptoms may have difficulty providing reliable information. Clinicians can use adaptation strategies (simpler language, visual supports, involve family informant), but validity may be compromised. Clinical judgment about whether the tool is appropriate is essential.
What if scores show low volition (interests, values) but adequate habituation and performance?
A profile with low volition but adequate routines and capacity suggests the client has the ability and structure to do occupations but lacks intrinsic motivation or engagement. This profile might indicate depression, burnout, or life dissatisfaction. Therapy might focus on exploring values, rekindling interests, and rebuilding motivation through meaningful activities—as opposed to focusing on routines or capacity-building, which are already adequate.
Can the MOHO-ST be used in non-mental health settings?
Yes, absolutely. The MOHO-ST is applicable across occupational therapy practice: physical rehabilitation, vocational rehabilitation, aging, pediatrics (with age-appropriate adaptation), and community settings. MOHO concepts (motivation, routines, capacity, environment) are universal. However, domain profiles may differ by setting; in physical rehabilitation, performance capacity may be central; in vocational settings, volition and habituation may be key.
How often should MOHO-ST be readministered?
The MOHO-ST can be readministered at intervals appropriate to the client and therapy intensity (monthly in active therapy, quarterly in longer-term care). Readministration allows tracking changes in occupational motivation and engagement and identifies shifting therapy priorities. Comparison across administrations provides quantitative and qualitative evidence of occupational progress.
