Factor structure of quality of life: The Lehman interview

This study of 67 chronically mentally ill outpatients with psychotic disorders examined subjective quality of life scores from Lehman's Quality of Life (QOL) interview. Factor analyses identified ‘Affiliative’ and ‘Instrumental’ dimensions which accounted for 67% of the variance in subjective satisfaction ratings. The results suggest a model in which instrumental and affiliative needs comprise significant portions of subjective life satisfaction and that global QOL satisfaction is related more to instrumental than affiliative needs. These findings further clarify the concept of life satisfaction in this population of severely mentally ill individuals and suggest modifications in how quality of life information is evaluated.     

On Criteria of Insignificant Difference Between Two Risks

The comparison and ranking of risks is very important for safety and cost-benefit analysis. Most formats present risks in the form of probability distribution. Different ranking criteria for probability distributions are considered. It is demonstrated that significantly overlapping distributions lead to ambiguous results. For this reason, criteria of insignificant overlapping distributions are proposed. The first criterion uses the information theory approach; and the second criterion uses the statistical tests approach. Both approaches can be applied to decision theory to avoid questionable decisions based on statistically insignificant differences between two risks.     

Obstacles to victims' cooperation with the criminal prosecution of their abusers: the role of social support

Over the last 20 years, diminishing tolerance for domestic violence has triggered significant criminal justice reforms designed to facilitate the prosecution of abusers. Prosecutors, for example, have adopted policies requiring that cases go forward even if the victim later has second thoughts. Although increasingly common, these "no drop" policies reflect a profound irony about domestic cases that is well known but little understood: the most formidable problem in prosecuting such cases is often the victim's own unwillingness to bring the abuser to justice. This prospective study explored a range of factors potentially predictive of domestic violence victims' cooperation with the prosecution of their abusers. Although the study focused on interpersonal and institutional social support, it also investigated the influence of violence severity, victim demographic factors, and victim mental health characteristics, including the presence of depressive symptoms, emotional dependence on the abuser, and substance abuse. Findings showed that tangible support, severity of violence in the relationship, and the presence of children in common with the abuser all significantly predicted victims' cooperation with the prosecution of their abusers. Substance abuse significantly predicted victims' noncooperation with prosecution. The research and policy implications of these findings are discussed.
