Measures of identity in adolescents/young adults with long-term physical health conditions: a systematic review.
Synthesis in Journal of pediatric psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe identified and evaluated measures of identity used with adolescents/young adults aged 16-24 years living with long-term physical health conditions (LTC-P), focusing on the conceptualization, development, and psychometric properties of measures. Review funded by Sir Halley Stewart Trust and the University of Bath. Review protocol: https://osf.io/bhkze.
methodFive databases (APA PsychNET, PubMed, Web of Science, SCOPUS, and CINAHL) were searched. Studies were included if they were peer-reviewed, reported participants aged 16-24 years with LTC-P, and used a quantitative identity measure. Psychometric properties and risk of bias were evaluated using Consensus-Based Standards for the Selection of Health Measurement Instruments V1 (COSMIN) quality criteria, and content validity was reviewed narratively. Data analysis and synthesis followed COSMIN methodology for reviews.
resultsThirty-seven papers met inclusion criteria, involving 9,486 participants and 16 identity measures. Across the papers, identity was defined and conceptualized in varied ways. Only three measures, the Illness Identity Questionnaire (IIQ), Dimensions of Identity Development Scale (DIDS), and Identity Motives Scale (IMS), were used in multiple studies and assessed for psychometric quality. Evaluated properties included structural validity, internal consistency, measurement invariance, and construct validity. The IIQ and DIDS were tentatively recommended for use. The IMS was rated as needing further validation due to limited content validity.
conclusionsThe IIQ and DIDS may be appropriate when their conceptual focus aligns with research objectives. Remaining measures should be used cautiously; many lack developmental or condition-specific relevance. Future identity measure development should integrate lived experience, expert input, and rigorous psychometric testing to ensure tools are both meaningful and fit for purpose in target populations.
