本研究では発達障害,精神疾患などにより生じる感覚処理の問題を包括的に評価する尺度として国際的に広く利用されている感覚プロフィールの日本版(SP-J)を開発し,1,441名のコミュニティサンプルのデータに基づき,その信頼性と標準値を検討した。大部分の項目で十分な修正済み項目―合計相関が示され,内的整合性の指標であるα係数もフロア効果が著しい一部の下位尺度を除いておおむね十分な値が得られた。原版の適用範囲である3~10歳と11歳以上では,修正済み項目―合計相関もα係数も同等の結果が得られ,11歳以上にも同等の信頼性で測定を行えることが示唆された。7年齢帯ごとの標準値が得られ,SP-Jによる感覚異常の評価が可能になった。
In the present study, we developed and standardized a Japanese version of the Sensory Profile (SP-J), which is used internationally to assess sensory processing abilities. We examined its psychometric properties with data from a community sample (n=1,441;age, 3-82 years). The corrected item-total correlations for most items of the SP-J subscales were adequate. Except for a few subscales that were affected by a floor effect, most subscales had a sufficiently high Cronbach's α coefficient, which is an indicator of internal consistency. In order to examine whether the instrument could be extended over a wider range of ages than that assumed in its original version (3-10 years), we compared the corrected item-total correlations and α coefficients between 2 age groups:3-10 years and 11-82 years. We found that the SP-J had the same level of reliability for these 2 groups. We also obtained norms for 7 age groups. These findings enable assessments of sensory processing with the SP-J in subjects of all ages.
