The presence of the general factor in interest and self-efficacy assessment and its meaning are reviewed.
The general factor is found in all interest and self-efficacy assessment and has been viewed as:
- a nuisance factor with little effect on assessment,
- a variable having substantive meaning and thus worthy of including in interpretation, and
- as systematic bias that distorts the interpretation of the meaning of assessments.
Methods of correcting this contamination are presented.
► The general factor is present in all interest and self-efficacy measurement.
► The general factor is nuisance, has meaning or is bias depending upon context.
► Narrow interest scales are subject to systematic bias.
► Only by ipsatizing narrow interest scales can valid interpretations result.
