This article presents psychometric characteristics of the UCLA PTSD Reaction Index for DSM IV (PTSD-RI) derived from a large sample of children and adolescents (N = 6,291) evaluated at National Child Traumatic Stress Network centers. Overall mean total PTSD-RI score for girls was significantly higher as compared with boys. Age-related differences were found in that overall mean total PTSD-RI scores and within sex groups were higher among those aged 7–9 years and 16–18 years. There were no significant differences in mean total PTSD-RI scores across racial/ethnic groups. The PTSD-RI total scale displayed good to excellent internal consistency reliability across age ranges, sex, and racial/ethnic groups (α = .88–.91). Correlations of PTSD-RI scores with PTS subscale scores on the TSCC-A for the entire sample and within sex, age, and ethnic/racial groups provided evidence of convergent validity, although not discriminant validity. In contradistinction to previously reported 4-factor models, an exploratory factor analysis revealed 3 factors that mostly reflected the underlying dimensions of PTSD in DSM IV. PTSD-RI scores were associated with increased odds ratios for functional/behavior problems (odds ratio [OR] = 1–1.80). These findings are striking in light of the wide range of trauma exposures, age, and race/ethnicity among subjects.

標題:UCLA PTSD反應指數的心理測量特徵:第一部份

撮要:全國兒童創傷壓力網絡中心求助的青少年和兒童人的大型樣本(=6291)會被評估,而本文則報告其中DSM IV的UCLA PTSD反應指數(PTSD-RI)的心理測量特徵。總平均PTSD-RI分數看來,女性比男性有統計上顯着較高分數;而且年紀相關的差別亦展示出來,在同一性別組別內7-9歲和16-18歲有較大差別;至於種族組別未見有任何顯着差別。PTSD-RI總量表在不同年齡層、性別和種族中有極好的內在一致性信賴度(α=.88至.91)。TSCC-A內PTSD-RI分數與PTS子副量表分數的相關關係,在整個樣本中和相同性別、年齡和種族組別中,都有聚合有效性,但郤沒有分辨有效性。與前述4-因子模型不同,探索性因子分析顯示3因子已能最有效反映PTSD在DSM IV的內在量度。PTSD-RI分數和功能/行為問題的高優勢比有相連(OR=1至1.80)。樣本中創傷經歷、年齡和種族有廣闊覆蓋面,而本硏究發現是矚目的。
