Mand Training: An Examination of Response-Class Structure in Three Children With Autism and Severe Language Delays

Our primary purpose in this study was to examine the structure of a response class when new members are acquired through mand training. To do this, we replaced existing mands (e.g., reaching) in three children with autism with two new functionally equivalent mands. Next, we examined their responding under immediate- and delayed-reinforcement conditions. Then, we assessed generalization to novel social partners. We employed a reversal design to examine the effectiveness of mand training and to assess responding under both immediate- and delayed-reinforcement conditions. Our results suggest that all children acquired the new mands and that two of the children emitted these responses as replacements when the social partner did not provide access to the reinforcer contingent on the child\u27s first mand. Generalization data indicate that all three children emitted the new mands and two of the children alternated between the new mands with novel social partners. We discuss the clinical implications and the conceptual significance of teaching multiple replacement mands to children with autism and severe language delays

Equivalence of Narcissistic Personality Inventory constructs and correlates across scoring approaches and response formats

The prevalent scoring practice for the Narcissistic Personality Inventory (NPI) ignores the forced-choice nature of the items. The aim of this study was to investigate whether findings based on NPI scores reported in previous research can be confirmed when the forced-choice nature of the NPI’s original response format is appropriately modeled, and when NPI items are presented in different response formats (true/false or rating scale). The relationships between NPI facets and various criteria were robust across scoring approaches (mean score vs. model-based), but were only partly robust across response formats. In addition, the scoring approaches and response formats achieved equivalent measurements of the vanity facet and in part of the leadership facet, but differed with respect to the entitlement facet

Limited validity of the Hospital Anxiety and Depression Scale (HADS) in dementia: evidence from a confirmatory factor analysis

OBJECTIVES: The Hospital Anxiety and Depression Scale (HADS) is a well-validated, self-report measure of both anxiety and depression. It is frequently used with people with dementia. However, its structural validity has never been examined in this population. The current study used confirmatory factor analysis (CFA) to assess this. METHODS: Baseline data from two intervention studies for people with mild to moderate dementia were combined (N = 268). CFA was used to test whether a one, two or three factor structure best fit the data. Indices of model misspecification were examined to test for poor quality items, and models re-specified accordingly. Finally, measurement invariance across gender and different levels of cognitive impairment was assessed. RESULTS: A one-factor structure did not fit the data. Two and three factor structures fitted the data equally well. Model fit was improved by removal of two items. Measurement invariance was adequate across gender, but poor across groups with differing levels of cognitive impairment. CONCLUSION: The HADS is acceptable and feasible but difficult to interpret in a dementia population. We suggest that it should be interpreted as measuring two separate factors of anxiety and depression and not one 'distress' factor. However, two items may need to be removed, affecting cut-off scores. Poor measurement invariance means the HADS may not be a good tool for measuring differences in anxiety and depression between those with mild and those with moderate cognitive impairment

THE MODERATING ROLES OF RACE AND GENDER-ROLE ATTITUDES IN THE RELATIONSHIP BETWEEN SEXUAL HARASSMENT AND PSYCHOLOGICAL WELL-BEING

Although previous research has linked sexual harassment to negative psychological outcomes, few studies have focused on moderators of these relationships. The present study surveyed Black (n = 88) and White (n = 170) female undergraduates who endorsed experiences of sexual harassment to examine whether traditional gender attitudes differentially moderated the relationship between sexual harassment and three outcomes: posttraumatic stress symptoms, general clinical symptoms, and satisfaction with life. We replicated past findings that sexual harassment is related to negative outcomes. Further, the results supported our hypothesis that less traditional gender attitudes (i.e., more feminist attitudes) would buffer the negative effects of sexual harassment for White women, whereas the same attitudes would exacerbate its negative effects for Black women. We discuss reasons for these differences, including Black women's double consciousness and differences in the meaning of feminist and traditional gender attitudes for Black and White women. Across a variety of settings, including academia, sexual harassment has been found to be one of the most common forms of gendered violence and has consistently been associated with detrimental psychological, physical, and academic/occupational consequences (e.g., We would like to thank Zaje Harrell and Abigail Stewart for their helpful comments on drafts of this article.

We suggest that the relationship between sexual harassment and psychological outcomes will be affected by the extent to which women hold traditional gender attitudes and that this relationship will differ for White and Black women. We theorize that, for White women experiencing sexual harassment, less traditional (more feminist) attitudes may allow them to attribute their negative treatment to external, social factors, which may lead to more positive psychological outcomes than women with more traditional gender attitudes. However, for Black women, less traditional attitudes may heighten awareness of oppression based on their multiple devalued group memberships, resulting in worse psychological outcomes than those with more traditional gender attitudes.

Reconsidering cluster bias in multilevel data: A Monte Carlo comparison of free and constrained baseline approaches

The test for item level cluster bias examines the improvement in model fit that results from freeing an item’s between level residual variance from a baseline model with equal within and between level factor loadings and between level residual variances fixed at zero. A potential problem is that this approach may include a misspecified unrestricted model if any non-invariance is present, but the log-likelihood difference test requires that the unrestricted model is correctly specified. A free baseline approach where the unrestricted model includes only the restrictions needed for model identification should lead to better decision accuracy, but no studies have examined this yet. We ran a Monte Carlo study to investigate this issue. When the referent item is unbiased, compared to the free baseline approach, the constrained baseline approach led to similar true positive (power) rates but much higher false positive (Type I error) rates. The free baseline approach should be preferred when the referent indicator is unbiased. When the referent assumption is violated, the false positive rate was unacceptably high for both free and constrained baseline approaches, and the true positive rate was poor regardless of whether the free or constrained baseline approach was used. Neither the free or constrained baseline approach can be recommended when the referent indicator is biased. We recommend paying close attention to ensuring the referent indicator is unbiased in tests of cluster bias.

The Consequences of Ignoring Measurement Invariance for Path Coefficients in Structural Equation Models

We report a Monte Carlo study examining the effects of 2 strategies for handling measurement non-invariance - modeling and ignoring non-invariant items - on structural regression coefficients between latent variables measured with Item Response Theory models for categorical indicators. These strategies were examined across 4 levels and 3 types of non invariance – non-invariant loadings, non-invariant thresholds, and combined non-invariance on loadings and thresholds - in simple, partial, mediated and moderated regression models where the non-invariant latent variable occupied predictor, mediator, and criterion positions in the structural regression models. When non-invariance is ignored in the latent predictor, the focal group regression parameters are biased in the opposite direction to the difference in loadings and thresholds relative to the referent group (i.e. lower loadings and thresholds for the focal group lead to overestimated regression parameters). With criterion non-invariance, the focal group regression parameters are biased in the same direction as the difference in loadings and thresholds relative to the referent group. While unacceptable levels of parameter bias were confined to the focal group, bias occurred at considerably lower levels of ignored non-invariance than was previously recognized in referent and focal groups
