Lakaev Academic Stress Response Scale-2 LASRS-2
Summary
The Lakaev Academic Stress Response Scale-2 (LASRS-2) psychometric tool has been developed through Rasch Modeling so that researchers, clinicians and educators can screen, assess and monitor tertiary-level students suffering academic stress. Gender Invariance Testing was implemented. A Provisional Therapeutic-cut-off-score and Optimal-cut-off-points were developed. A Rasch Keyform for practitioners was derived to help interpret the LASRS-2 measurement instrument when there are anomalous presentations or missing data. A LASRS-2 Domain Diagnostic Tool for the Affective, Behavioural, Cognitive and Physiological Domains. Finally, the Demographics were subjected to statistical analysis to compare differing educational levels, cultural groups, faculties and gender.

LASRS-2 Keyform (resource)
"The LASRS-2 Keyform is a helpful resource (tool) within clinical and/or educational settings. Please see below. A Rasch Keyform was designed to help identify academic stress presentations. The Keyform's visual layout enables the user (a diagnostician or clinician) in the field to do a sophisticated analysis of an individual without reliance on computer software. The LASRS-2 Keyform allows the practitioner to produce an Overall LASRS-2 score (academic stress score) even when faced with missing data, anomalous educational stress presentations or problematic items.
To develop the LASRS-2 Keyform, Rasch Analysis converted Category Rating scale results into True Interval Measures (Wright & Linacre, 1989). This is done by forming ratios of intervals rather than assigning ordinal (raw) numbers (Ewing, Salzberger, & Sinkovics, 2005). The use of measures derived by this method is limited in everyday clinical and educational settings as raw data has to be inputted into software and then computer-scored (Linacre, 1997). The Keyform method is an alternative to computer scoring. It is a paper-and-pen based psychometric tool that allows the practitioner to record and convert ratings to Interval Measures while exercising intuitive quality control of the student’s data so that it can be used beneficially for an individual (or cohort) with which a clinician or educator is therapeutically engaged (Linacre, 1997). As practice-based clinicians rarely have the time and the resources to spend hours statistically analyzing their client results and then to cross-correlate these same results against a variety of research conclusions, the LASRS-2 Rasch Keyform provided a complete and instant view (Linacre, 1997) of a participant’s academic stress level responses.
The LASRS-2 Keyform provides a visual plot on Side B (the bottom half) of the LASRS-2 questionnaire."
