Idiographic patient reported outcome measures (I-PROMs) for routine outcome monitoring in psychological therapies: Position paper

Idiographic patient-reported outcome measures (I-PROMs) are a growing set of individualized tools for use in routine outcome monitoring (ROM) in psychological therapies. This paper presents a position statement on their conceptualization, use, and analysis, based on contemporary evidence and clinical practice. Four problem-based, and seven goal-based, I-PROMs, with some evidence of psychometric evaluation and use in psychotherapy, were identified. I-PROMs may be particularly valuable to the evaluation of psychological therapies because of their clinical utility and their alignment with a patient-centered approach. However, there are several challenges for I-PROMs: how to generate items in a robust manner, their measurement model, methods for establishing their reliability and validity, and the meaning of an aggregated I-PROM score. Based on the current state of the literature, we recommend that I-PROMs are used to complement nomothetic measures. Research recommendations are also made regarding the most appropriate methods for analyzing I-PROM data.

Measuring psychological outcomes in paediatric settings: Making outcomes meaningful using client-defined perspectives

There is a growing drive to develop and implement patient-reported outcome measures within paediatric health services, particularly for young people living with chronic health conditions; however, there is little consensus on how best to do this in meaningful ways within psychological services working alongside medical teams. This reflective commentary considers some of the challenges of collecting psychological outcome measures in paediatric services and considers alternative approaches to making outcome measurement meaningful. All measures have their limitations; however, they become meaningless if they are not used in meaningful and considered ways with young people. Client-defined outcome measurement, such as goal-based outcome measures, alongside other types of measurement, can capture outcomes of meaning to young people living with chronic health conditions, and can enable them to feed into a shared decision-making process.

A note on contemporary psychometrics

Psychometrics provide the mathematical underpinnings for psychological assessment. From the late 19th century, a plethora of methodological research achievements equipped researchers and clinicians with efficient tools whose practical value becomes more evident in the era of the internet and big data. Nowadays, powerful probabilistic models exist for most types of data and research questions. As the usability of the psychometric scales is better comprehended, there is an increased interest in applied research outcomes. Paradoxically, while the interest in applications for psychometric scales increases, publishing research on the development and/or evaluation of those scales per se, is not welcomed by many relevant journals. This special issue in psychometrics is therefore a great opportunity to briefly review the main ideas and methods used in psychometrics, and to discuss the challenges in contemporary applied psychometrics.
