A nationwide epidemiologic modeling study of LD: risk, protection, and unintended impact

Through multiple logistic regression modeling, this article explores the relative importance of risk and protective factors associated with learning disabilities (LD). A representative national sample of 6- to 17-year-old students (N = 1,268) was drawn by random stratification and classified by the presence versus absence of LD in reading, spelling, and mathematics according to ability-achievement discrepancies or low achievement levels. The dichotomous classifications were regressed on sets of explanatory variables indicating potential biological, social-environmental, and cognitive factors, problem behavior, and classroom learning behavior. Modeling revealed patterns of high risk for male students and students evincing verbal and nonverbal ability problems and processing speed problems. It was shown that, absent controls for cognitive abilities (such as provided by the ability-achievement discrepancy definition), definitions keyed to low achievement will substantially overidentify ethnic minority and disadvantaged students and will be confounded by significantly higher proportions of students who display oppositional and aggressive behavior problems. Alternatively, good learning behaviors uniformly provide substantial reduction in the risk for LD.     

Effects of mother-son incest and positive perceptions of sexual abuse experiences on the psychosocial adjustment of clinic-referred men

OBJECTIVE: The primary objective was to examine the long-term impact of mother-son incest and positive initial perceptions of sexual abuse experiences on adult male psychosocial functioning. METHOD: Sixty-seven clinic-referred men with a history of sexual abuse participated. The participants completed self-report measures regarding their current psychosocial functioning and described the nature of their sexual and physical abuse experiences during childhood. RESULTS: Seventeen men reported mother-son incest, and these men endorsed more trauma symptoms than did other sexually abused men, even after controlling for a history of multiple perpetrators and physical abuse. Mother-son incest was likely to be subtle, involving behaviors that may be difficult to distinguish from normal caregiving (e.g., genital touching), despite the potentially serious long-term consequences. Twenty-seven men recalled positive or mixed initial perceptions of the abuse, including about half of the men who had been abused by their mothers. These men reported more adjustment problems than did men who recalled purely negative initial perceptions. CONCLUSIONS: Mother-son incest and positive initial perceptions of sexual abuse experiences both appear to be risk factors for more severe psychosocial adjustment problems among clinic-referred men.
