Identifying measures that reliably and validly assess clinical impairment has important implications for eating disorder (ED) diagnosis and treatment. The current study examined the psychometric properties of the Clinical Impairment Assessment (CIA) in women at high risk for ED onset. Participants were 543 women (20.6 ± 2.0 years) who were classified into one of three ED categories: clinical ED, high risk for ED onset, and low risk control. Among high risk women, the CIA demonstrated high internal consistency (α = 0.93) and good convergent validity with disordered eating attitudes (rs = 0.27-0.68, ps < 0.001). Examination of the CIA's discriminant validity revealed that CIA global scores were highest among women with a clinical ED (17.7 ± 10.7) followed by high risk women (10.6 ± 8.5) and low risk controls (3.0 ± 3.3), respectively (p < 0.001). High risk women reporting behavioral indices of ED psychopathology (objective and/or subjective binge episodes, purging behaviors, driven exercise, and ED treatment history) had higher CIA global scores than those without such indices (ps < 0.05), suggesting good criterion validity. These data establish the first norms for the CIA in a United States sample. The CIA is psychometrically sound among high risk women, and heightened levels of impairment among these individuals as compared to low risk women verify the relevance of early intervention efforts. 相似文献

Children with an autism spectrum disorder (ASD) may play with limited objects or toys, making it difficult for teachers to identify reinforcers to use in teaching new skills. The goal of this study was to alter children's preferences from highly preferred toys to toys that were originally less preferred using an observational pairing procedure. Child participants observed a preferred adult playing with toys that were initially less preferred by the child. This intervention resulted in a shift in preference toward the item manipulated by the adult. Maintenance of the changed preference was idiosyncratic across participants. Results suggest a procedure for expanding the range of items that students with ASD will select. 相似文献

Research has suggested that a daily multiple‐stimulus‐without‐replacement (MSWO) preference assessment may be more sensitive to changes in preference than other assessment formats, thereby resulting in greater correspondence with reinforcer efficacy over time ( DeLeon et al., 2001 ). However, most prior studies have measured reinforcer efficacy using rate of responding under single‐operant arrangements and dense schedules or under concurrent‐operants arrangements. An alternative measure of reinforcer efficacy involves the evaluation of responding under progressive‐ratio (PR) schedules. In the present study, 7 participants were given a single paired‐stimulus (PS) preference assessment followed by daily MSWO preference assessments. After each daily MSWO, participants responded for each stimulus on a PR schedule. The correspondence between break points and preferences, as assessed by the 2 assessment formats, was examined. Results demonstrated that both preference assessments did equally well at predicting reinforcer efficacy, although the PS more consistently identified the most effective reinforcer. 相似文献

Using the Name Connotation Profile, English Canadian and French Canadian university students rated their impressions of people with English or French first names. Both the English and French students formed a more favorable impression of people who had names from their own linguistic group. These results are consistent with social identity theory, according to which people define themselves in part by groups to which they belong, with the contact hypothesis, according to which people feel more positively towards those with whom they have interacted more, and perhaps with the mere exposure effect, according to which liking for an object increases with the frequency with which it is presented. 相似文献

We explored the functional organization of semantic memory for music by comparing priming across familiar songs both within
modalities (Experiment 1, tune to tune; Experiment 3, category label to lyrics) and across modalities (Experiment 2, category label to tune; Experiment 4, tune to lyrics). Participants judged whether or not the target tune or lyrics were real (akin to lexical decision tasks).
We found significant priming, analogous to linguistic associative-priming effects, in reaction times for related primes as
compared to unrelated primes, but primarily for within-modality comparisons. Reaction times to tunes (e.g., “Silent Night”)
were faster following related tunes (“Deck the Hall”) than following unrelated tunes (“God Bless America”). However, a category
label (e.g., Christmas) did not prime tunes from within that category. Lyrics were primed by a related category label, but not by a related tune.
These results support the conceptual organization of music in semantic memory, but with potentially weaker associations across
modalities. 相似文献
