Purpose

An assessment that addresses the majority of MOHO concepts:
volition (motivation for occupation), habituation (pattern of occupation), communication and interaction skills, motor skills, process skills, environment in order to gain an overview of occupational functioning.

Non-Specific Patient Population

24 items (4 items per section)
Minimum score 24, Maximum score 96
Each item is scored on an ordinal rating scale:
F= facilitates occupation participation;
A= allows occupation participation;
I= inhibits occupation participation;
R= restricts occupation participation;
Can be translated into a 4-point interval rating scale where F=4, A=3, I=2, and R=1.
The MOHOST manual provides descriptions of criteria for each item.

Interrater/Intrarater Reliability

Mental Health:

See: (Forsynth et al, 2011, n = 163; mean age = 40.10 years; 83.4% male, 16.56% female; 48% from UK, 52% from USA; Mental Health)

Internal Consistency

Mental Health:

(Kramer et al, 2009, n = 54; mean age = 58.13; 20 male, 34 female from inpatient rehabilitation unit; spent between 2 and 39 days on the unit M = 11.54, SD = 7.518; Mental Health)

Mixed Disabilities
See: (Kielhofner, 2009, n = 166; mean age = 40.1 years; 83.7% male and 16.3% female; 51.8% from the UK, 48.2% from the USA; Mixed Disabilities)

Construct Validity

Convergent Validity

MOHOST-C Volitional Scale & Volitional Questionnaire: Adequate r= 0.583
MOHOST-C Communication Scale & ACIS-C: Excellent r= 0.815
MOHOST-C Process Scale & MMSE: Adequate r= 0.334

Divergent Validity

Mental Health
(Pan et al, 2011, n = 101; mean age = 40.5 (9.6) years; n = 74 patients with schizophrenia, Mental Health)

Poor reliability between volition subscale of MOHOST and Volitional Questionnaire (r = -.048)
Poor reliability between habituation subscale of MOHOST and Volitional Questionnaire (r= .046)
Poor reliability between communication subscale of MOHOST and Volitional Questionnaire (r= .104)
Poor reliability between process subscale of MOHOST and Volitional Questionnaire (r = .005)
Poor reliability between motor subscale of MOHOST and Volitional Questionnaire (r = .042)
Poor reliability between environment subscale of MOHOST and Volitional Questionnaire (r = -.013)

Content Validity

Mental Health
(Pan et al, 2011, Mental Health)

Excellent correlation between volition subscale of MOHOST and Volitional Questionnaire ( r = .583)
Excellent correlation between communication and interaction subscale of MOHOST and the ACIS ( r =.815)
Adequate correlation between process subscale of MOHOST and MMSE (r = .334)

Mental Health:
(Kielhofner, 2010; n= 1039; mean age= 61.83 (22.28) years, Mental Health)

All six subscales of the MOHOST were able to discriminate subjects into at least three statistically distinct levels. The reliability with which subjects were discriminated into levels ranged from .81 to .89
Poor correlation with MOHOST subscale volition with HoNOS-PbR item Problems with ADLs (r= .23)
Poor correlation with MOHOST subscale Habituation with HoNOS-PbR item Problems with ADLs (r= .29)
Poor correlation with MOHOST subscale Communication/ interaction skills with HoNOS-PbR item Problems with relationships (r= .20)
Adequate correlation with MOHOST subscale process skills with HoNOS-PbR item cognitive problems (r= .45)
Adequate correlation with MOHOST subscale Motor Skills with HoNOS-PbR item Physical illness or disability problems (r= .43)
Poor correlation with MOHOST subscale Environment with HoNOS-PbR item Problems with living conditions(r= .24)
