Testing an integrated self-determined work motivation model for people with disabilities: A path analysis

Area of Science:

• Rehabilitation Psychology
• Vocational Psychology
• Disability Studies

Background:

• Individuals with disabilities face significant barriers to employment and economic stability.
• Amotivation and ambivalence towards employment can hinder engagement with vocational rehabilitation services.
• Existing theories like self-efficacy, self-determination, and stages of change offer insights into work motivation.

Purpose of the Study:

• To develop and test an integrated self-determined work motivation model for people with disabilities.
• To examine the interplay of functional disability, self-determination, and social efficacy in predicting work motivation.
• To provide a framework for enhancing vocational rehabilitation outcomes.

Main Methods:

• A sample of 277 individuals with disabilities was recruited from vocational rehabilitation agencies across eight states.
• Path analysis was employed to evaluate the hypothesized integrated self-determined work motivation model.
• Model fit was assessed using maximum likelihood estimation and goodness-of-fit indices, with post hoc modifications made.

Main Results:

• The initial model required respecification for optimal fit.
• The revised integrated self-determined work motivation model demonstrated excellent fit with the data (CFI = .99, RMSEA = 0.056).
• The model explained a substantial portion of the variance in endogenous variables (R² ranging from .19 to .54).

Conclusions:

• The integrated self-determined work motivation model provides a robust framework for understanding work motivation in vocational rehabilitation.
• The model highlights the importance of functioning levels, self-determination, and self-efficacy in predicting vocational rehabilitation engagement and employment readiness.
• Findings support the model's utility in guiding interventions to improve employment outcomes for individuals with disabilities.
