4. IPS Fidelity Scale Reliability
Content Validity
Discriminative Validity
Sensitivity to Change
Predictive Validity
5. IPS Fidelity Scale Description 25 items
Each item rated using a 1-5 score
115-125 exemplary fidelity
100-114 good fidelity
74-99 fair fidelity
73 and below not IPS
Oregon requires minimum score of 100
6. Highly Correlated Fidelity Items Community based services
Full time employment specialists (Becker et al 2001)
Rapid job search
Focus on competitive employment (McGrew 2007)
7. Other Key Factors Job selection, integration with treatment team, quality of job development and vocational staffing most strongly differentiate IPS from other employment models. (Bond et al 2001)
Consumer surveys indicate the quality of relationships with IPS staff and “practice assistance” are experienced as the most important aspects. (Johnson et al., 2009; Taylor, 2007)
8. Other Key Factors For successful implementation (high fidelity) strong leadership and mastery of key skills are positive factors
Lack of leadership and negative attitudes about the IPS model correlate with unsuccessful implementation (low or no fidelity). (Marshal et al 2008)
