With the rise in efforts to evaluate the quality of mental health care and its outcomes, the measurement of change has become an important topic. This paper tracks the creation of a new instrument designed to assess psychotherapy outcome. The Outcome Questionnaire (OQ) was designed to include items relevant to three domains central to mental health: subjective discomfort, interpersonal relations, and social role performance. This study describes the theoretical development and psychometric properties of the OQ. Psychometric properties were assessed using clinical, community, and undergraduate samples. The OQ appears to have high reliability and evidence to suggest good concurrent and construct validity of the total score. The data presented show that it distinguishes patient from non‐patient samples, is sensitive to change, and correlates with other measures of patient distress.

A program of research aimed at improving the quality of psychological interventions is described. Data from over 10,000 patients were analyzed to understand the association between number of treatment sessions and clinically significant improvement. In addition to a potential dose-response relationship, typical recovery curves were generated for patients at varying levels of disturbance and were used to identify patients whose progress was less than expected ("signal" cases). The consequences of passing this information along to therapists were reported. Analyses of dose-response data showed that 50% of patients required 21 sessions of treatment before they met criteria for clinically significant improvement. Seventy-five percent of patients were predicted to improve only after receiving more than 40 treatment sessions in conjunction with other routine contacts, including medication in some cases. Identification of signal cases (potential treatment failures) shows promise as a decision support tool, although further research is needed to elucidate the nature of helpful feedback. Outgrowths of this research include its possible contribution to social policy decisions, reductions in the need for case management, use in supervision, and possible effects on theories of change.

To date, few studies have been published on the dose‐response relationship, but there is general consensus that between 13 and 18 sessions of therapy are required for 50% of patients to improve. Reviewing the clinical trials literature reveals that in carefully controlled and implemented treatments, between 57.6% and 67.2% of patients improve within an average of 12.7 sessions. Using naturalistic data, however, revealed that the average number of sessions received in a national database of over 6,000 patients was less than five. The rate of improvement in this sample was only about 20%. These results suggest that patients, on average, do not get adequate exposure to psychotherapy, nor do they recover from illness at rates observed in clinical trials research.

Objective: to assess the co-occurrence of patterns of adolescent substance use and sexual behavior and test for potential moderating effects of gender. Method: the 2005 Youth Risk behavior survey sample of 13,953 high school students was used in this study. latent class analyses were conducted to examine the relation between patterns of substance use and sexual risk behavior in a nationally representative adolescent sample. the final model controlled for demographic covariates and an interaction between gender and substance-use classes. Results: Four class solutions to each behavior provided optimal fit. substance-use classes were nonusers (27%), alcohol experimenters (38%), occasional polysubstance users (23%), and frequent polysubstance users

Antiretroviral pre-exposure prophylaxis (PrEP) has received increasing recognition as a viable prescription-based intervention for people at risk for HIV acquisition. However, little is known about racial biases affecting healthcare providers’ willingness to prescribe PrEP. This investigation sought to explore medical students’ stereotypes about sexual risk compensation among Black versus White men who have sex with men seeking PrEP, and the impact of such stereotypes on willingness to prescribe PrEP. An online survey presented participants (n = 102) with a clinical vignette of a PrEP-seeking, HIV-negative man with an HIV-positive male partner. Patient race was systematically manipulated. Participants reported predictions about patient sexual risk compensation, willingness to prescribe PrEP, and other clinical judgments. Bootstrapping analyses revealed that the Black patient was rated as more likely than the White patient to engage in increased unprotected sex if prescribed PrEP, which, in turn, was associated with reduced willingness to prescribe PrEP to the patient.
