Multidimensional Health Locus of Control- Internal Scale (MHLC-I)
Description: A measure of an individual’s belief in his/her ability to control health outcomes .
Format: 18 items comprise the combined-form MHLC-I. Combining the two forms (A & B) increases the alpha reliability of the scale. Form C is designed to be “condition-specific” and can be used in place of Form A/B when studying people with an existing health/medical condition. Like Forms A/B, Form C also has 18 items, but, instead of a single 6 item powerful “others” subs-cale, Form C has two, independent 3 item subscales: doctors, and other people .
Scoring: Respondents are asked to indicate the extent to which they agree with each statement using a 6-point Likert scale.
Administration and Burden: Self-administered.
Psychometrics for SCI: From non-SCI populations, cronbach’s alpha coefficients ranging from .86 to .88 have been reported for the combined form MHLC-I . Convergent and predictive validities have also been reported . No psychometric data available for persons with SCI.
QoL Concept: The MHLC-I is a measure of Subjective Well-Being (Self-Efficacy), which corresponds to Box E (subjective well-being; self-efficacy) of Dijker’s Model.
