It is an important issue for patients with motor neurone disease who are likely to experience severe physical impairment. Model fit, category threshold analysis, differential item functioning DIFdimensionality and local dependency were evaluated. Factor analysis confirmed the suitability of the four-factor solution suggested by the original authors.
Mokken scale analysis suggested the removal of item five. Rasch analysis removed a further three items; from the Community one item and Emotional two items withdrawal subscales.
Following item reduction, each scale exhibited excellent fit to the Rasch model. A item Summary scale was slimming loove valvur to fit the Rasch model after subtesting the items into three subtests corresponding to the Community, Family and Emotional subscales, indicating that items from these three subscales could be summed together to create a total measure for social withdrawal.

Removal of four items from the Social Withdrawal Scale led to a four factor solution with a item hierarchical Summary scale that were all unidimensional, free for DIF and well fitted to the Rasch model. The scale is reliable and allows clinicians and researchers to measure social withdrawal in MND along a unidimensional construct.
