Description

Assessment and interpretation are imperative skills, central to the role of a psychologist. In many areas of psychological practice, assessment inventories, tests, checklists, and questionnaires are integral sources of information about an individual’s level of functioning, intellectual ability, mental capacity, and personality. Recommendations to decision-makers are based upon assessment outcomes. Selection of appropriate measures relies on the assumption that an instrument has demonstrated consistency in assessing symptoms with individuals over time. It is incumbent upon psychologists to select appropriate assessment measures that have demonstrated reliability akin to the population of their respondent, first, before inferring validity. Unfortunately, many often confuse reliability and validity, and this leads to the erroneous induction of validity as a property of the measure rather than attributed to the respondents. Reliability directly impacts the interpretability of assessment outcomes and, if not within an acceptable range, renders interpretation invalid. As reliability information is readily available when selecting assessments, this presentation will discuss where and how to find this valuable source of information. The presentation will provide clear definitions and examples of how to interpret reliability along with practical applications relatable to psychologists working in the areas of assessment and report writing.
