An evaluation of a generalized self-efficacy scale

Tipton and Worthington (1984; Journal of Personality Assessment, 48, 545–548) presented a scale for assessing generalized self-efficacy. This scale was available in two forms: an original version of 27 items and a brief version of 10 items. In the current study the reliability of both versions was found to be high although the predictive utility of the original scale was found to be low. It was concluded that the scale did fulfil some objectives as a generalized self-efficacy measure, but the usefulness of a generalized self-efficacy measure was called into question.
