Abstract
Four studies, involving 314 middle-aged and older adults were conducted to develop and validate the Occupational Self-Efficacy Index (OSEI). The OSEI assesses adults' beliefs (in the latter half of their working life) in their continued ability to learn, adapt, and be productive in a changing workplace. OSEI scores reflect three factors: Performance Ability, Learning Ability, and Organizational Skills. The instrument is reliable (alpha = .94). Evidence of construct validity included positive conelations with general self-efficacy, intrinsic job motivation, a history of previous job successes, retirement income sufficiency, health status, and a negative correlation with job stress.
