1 · What the graph read from it

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.

2 · The registry

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

backgroundSubstance use disorders (SUDs) are one of the nation's most costly problems in terms of dollars, disability, and death. Self-help programs are among the varied recovery support options available to address SUD, and evaluation of these programs depends on good measurement. There exists an unmet need for a psychometrically sound, brief, efficient measure of self-help involvement for individuals with SUD that is valid across different substances and age-groups.

methodsUsing data from 2,101 persons presenting for SUD treatment, the full 21-item Global Appraisal of Individual Needs Self-Help Involvement Scale (SHIS) and a newly developed 11-item short-form version were validated against the Rasch measurement model and each other. Differential item functioning (DIF) was assessed by primary substance and age.

resultsBoth versions met Rasch psychometric criteria. The full scale had minor misfit with no DIF for alcohol, marijuana, or opioids but a few instances of DIF for amphetamine and cocaine users as well as for age, in that youth tended to endorse several easier items more frequently than did adults. The 11-item short form had neither misfit nor DIF by substance and only minor DIF by age was highly correlated with the full version and was relatively more efficient. Criterion-related validity was supported for both.

conclusionsBoth the long and short versions of SHIS are psychometrically sound measures of a more comprehensive conceptualization of self-help involvement for SUDs that can be used as part of an in-depth assessment or as a short measure that lessens respondent burden.
