The Government of India (GOI) has recommended the use of Indian Disability Evaluation and Assessment Scale (IDEAS) for the assessment and certification of disability in patients with mental illness. Although data are available in terms of internal consistency and construct validity of IDEAS, concurrent validity of IDEAS has rarely been evaluated.
The aim was to study the concurrent validity of IDEAS with Global Assessment of Functioning (GAF) and Social and Occupational Functioning Scale (SOFS) in patients with schizophrenia.
One hundred and seventy-eight consenting patients with schizophrenia in remission were assessed for disability, functioning, and psychopathology using the IDEAS, SOFS, GAF, and Positive and Negative symptom scale (PANSS) respectively.
Mean total PANSS score was 51.3 (standard deviation SD -11.19). Disability (>40%) was present in 84.8% of the sample. All the component scores of IDEAS (self-care, interpersonal activities, communication, and work), total IDEAS score, and Global IDEAS score correlated significantly ( < 0.001) with the three domains of SOFS (adaptive life skills, social appropriateness and communication, and interpersonal relationships) along with the total SOFS score. GAF total score had significant negative correlation ( < 0.001) with all the components of IDEAS, total IDEAS score and global IDEAS score. Higher residual psychopathology was also associated with overall higher disability as assessed by total IDEAS score and Global IDEAS score.
This study shows that the GOI-modified IDEAS had good concurrent validity with global and sociooccupational functioning as assessed by GAF and SOFS respectively.
印度政府（GOI）已建议使用印度残疾评估量表（IDEAS）对精神疾病患者的残疾情况进行评估和认证。尽管已有关于IDEAS内部一致性和结构效度的数据，但IDEAS的同时效度很少被评估。
本研究旨在探讨IDEAS与精神分裂症患者的总体功能评定量表（GAF）和社会及职业功能量表（SOFS）的同时效度。
分别使用IDEAS、SOFS、GAF和阳性与阴性症状量表（PANSS）对178例处于缓解期且同意参与研究的精神分裂症患者的残疾情况、功能状况和精神病理学进行评估。
PANSS总分的平均值为51.3（标准差SD = 11.19）。样本中84.8%的患者存在残疾（>40%）。IDEAS的所有分量表得分（自我照料、人际活动、沟通和工作）、IDEAS总分以及IDEAS综合得分与SOFS的三个领域（适应性生活技能、社会适应性和沟通、人际关系）以及SOFS总分均显著相关（<0.001）。GAF总分与IDEAS的所有分量表得分、IDEAS总分以及IDEAS综合得分均呈显著负相关（<0.001）。根据IDEAS总分和IDEAS综合得分评估，较高的残留精神病理学也与总体较高的残疾程度相关。
本研究表明，GOI修订的IDEAS分别与通过GAF和SOFS评估的总体及社会职业功能具有良好的同时效度。
