Assessing biopsychosocial status in people living with HIV: validity, reliability, and responsiveness of BETY-BQ.
Article in BMC infectious diseases, 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
backgroundDespite the quality of life (QoL) and biopsychosocial model gain importance in the management of people living with HIV (PLWH), there is lack of a suitable tool addressing the current demand. This longitudinal methodological study describes the validity, reliability, and responsiveness of the Bilişsel Egzersiz Terapi Yaklaşımı-Biopsychosocial Questionnaire (BETY-BQ), which was previously designed to assess biopsychosocial characteristics, including pain coping skills, functionality, fatigue, emotional state, sleep, sexuality, and sociability, resulting from chronic diseases in PLWH.
methodsBETY-BQ was administered to a total of 150 PLWH in the outpatient clinics of two different hospitals. The Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale (HADS), the Clinical Frailty Scale (CFS), and the FRAIL Questionnaire were used for the validity. For both reliability and responsiveness analyses, assessments were conducted in 30 PLWH. Reliability was evaluated by repeating the assessments at 1-week intervals, and responsiveness was assessed by re-administering the same scales at 3-month intervals.
resultsModerate to high correlations were found between BETY-BQ and SF-36, HADS, CFS, FRAIL. The correlations between BETY-BQ and SF-36 subheadings ranged from rho=-0.497 to rho=-0.650, p < 0.001, while there were correlations with HADS-Anxiety (rho = 0.717, < 0.001), HADS-Depression (rho = 0.653, < 0.001), CFS (rho = 0.467, < 0.001), FRAIL (rho = 0.559, < 0.001). The score distribution refuted floor and ceiling effects. The reliability of BETY-BQ was confirmed by test-retest strategy (ICC = 0.951). The Cronbach’s α value was 0.943 for the test and 0.963 for the retest. The time-dependent change responsiveness of BETY-BQ was moderately correlated with the depression subheading of the HADS.
conclusionsBETY-BQ is as a valid and reliable instrument by which, multidisciplinary-interdisciplinary healthcare teams can evaluate the biopsychosocial features among PLWH in a holistic and practical manner. Preliminary findings also suggest its potential sensitivity to change, particularly concerning depressive symptoms; however, further studies are needed to establish its responsiveness fully.
