Please note: there may be some adjustments to the teaching arrangements published in the course catalogue for 2020-21. Given current circumstances related to the Covid-19 pandemic it is anticipated that some usual arrangements for teaching on campus will be modified to ensure the safety and wellbeing of students and staff on campus; further adjustments may also be necessary, or beneficial, during the course of the academic year as national requirements relating to management of the pandemic are revised.

Short Description

Students will work in small groups to create and evaluate a measurement tool using predominantly quantitative methods, with additional qualitative techniques. Students will generate items to create a tool that measures a psychological construct and is informed by existing literature. Students will then administer their tool and evaluate aspects of its reliability, validity and applicability, and write an independent test manual of these procedures.


Four one hour lectures.

Three 2 hour lab sessions.

Online support via Moodle forums (1 hour per week)

Requirements of Entry

A Grade D or better in Psychology 1A and 1B, and 2A and 2B.

'Test manual (75%) - 1500 words (end of semester)

INDIVIDUAL SUBMISSION. The test manual resembles a traditional report with some minor variation on presentation of content. Students will produce a test manual that introduces the measurement domain, its theoretical underpinnings, a review of empirical research, and the purpose of creating the measurement tool. The methodological section focuses on test development and evaluation, and includes multiple aspects of quantitative and qualitative psychometrics (e.g. reliability and validity). The last section includes a critical evaluation of the tool, its development and further refinement, as well as applicability and relevance (research and/or clinical practice) of the measure.


Project Output: Measurement tool/test (25%) - 750 words (halfway through semester)

GROUP SUBMISSION. Students will submit their test items as well as the iterative process undertaken for their development. Construct definition, rationale, and item generation must be outlined alongside the test items themselves. The usability, relevance, and quality of the measurement tool created by students will be evaluated. The individual items will be evaluated based on how they are informed by the literature and existing measurement tool.'

Course Aims

To work in small groups to create and evaluate a measurement tool using quantitative and qualitative methods.
