Measuring social difficulties in routine patient-centred assessment: a Rasch analysis of the social difficulties inventory.
Article in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 2 of them syntheses that pooled 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.
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
backgroundSocial difficulties may add to the psychological burden experienced by cancer patients. Therefore identifying social difficulties in routine oncology practice may help prevent or alleviate distress. The Social Difficulties Inventory (SDI) is a short questionnaire developed for assessing social difficulties in cancer patients. Although well-validated, not enough is known about the clinical meaning and utility of the instrument or whether the items can be meaningfully summed to form a summary index of "Social Distress". PURPOSE: To determine, using Rasch analysis, whether the SDI could be used as a summary index of social distress specifically examining three fundamental criteria: item fit, unidimensionality and item invariance.
methodsThe Partial Credit Model was applied to a heterogeneous sample of cancer patients (n = 609) who had completed the SDI.
resultsFive items were identified as misfitting (infit mean square > or = 1.3 and standardised t-statistic > or = 2) and excluded from the subsequent analysis. The remaining items formed a unidimensional interval scale with no additional factors identified in a principal components analysis of the residuals. No differential item functioning was observed for age, gender, diagnosis, extent of disease or social deprivation. The 16-item SDI can be summed to produce an overall index of social distress, facilitating routine identification of social difficulties. Subsequent work is needed to evaluate whether the instrument is able to identify patients with high levels of social distress requiring intervention.
