UP'S: A Cohort Study on Recovery in Psychotic Disorder Patients: Design Protocol.

Recovery is a multidimensional concept, including symptomatic, functional, social, as well as personal recovery. The present study aims at exploring psychosocial and biological determinants of personal recovery, and disentangling time-dependent relationships between personal recovery and the other domains of recovery in a sample of people with a psychotic disorder. A cohort study is conducted with a 10-year follow-up. Personal recovery is assessed using the Recovering Quality of Life Questionnaire (ReQoL) and the Individual Recovery Outcomes Counter (I.ROC). Other domains of recovery are assessed by the Positive and Negative Symptom Scale Remission (PANSS-R), the BRIEF-A and the Social Role Participation Questionnaire-Short version (SRPQ) to assess symptomatic, functional and societal recovery, respectively. In addition, multiple biological, psychological, and social determinants are assessed. This study aims to assess the course of personal recovery, and to find determinants and time-dependent relationships with symptomatic, functional and societal recovery in people with a psychotic disorder. Strengths of the study are the large number of participants, long duration of follow-up, multiple assessments over time, extending beyond the treatment trajectory, and the use of a broad range of biological, psychological, and social determinants.

Association Between Substance Use and the Perpetration of Family Violence in Industrialized Countries: A Systematic Review.

This review examines the association between alcohol and illicit drug use and the perpetration of intimate partner violence (IPV) and child maltreatment (CM). In clinical populations, alcohol use is related to IPV, although other variables are also known to influence this relationship. Studies in specialized social/health care and in the community have also demonstrated the association between alcohol use and IPV. Although data on the association between illicit drug use and IPV are less clear, in most studies perpetration seems related to the use of cannabis and cocaine. The occurrence of CM is related to alcohol use in specialized social/health care and community populations but has not been extensively investigated in clinical samples. These findings also apply to studies on the association between illicit drug use and CM. Moreover, many studies on CM fail to distinguish between the effects of alcohol and those of illicit drugs. This review concludes with recommendations for future research about substance use and family violence and discusses implications for prevention and treatment.

Pre-notification did not increase response rate in addition to follow-up: a randomized trial.

OBJECTIVE: Although there is growing evidence on the effectiveness of pre-notification and follow-up on response rates in patient surveys, no studies report the effectiveness of pre-notification in addition to follow-up. The aim of this study was to determine the effect of a pre-notification by mail on the response rate in a patient survey with follow-up, compared with follow-up or pre-notification only. STUDY DESIGN AND SETTING: Randomized trial that compared (1) a combination of pre-notification and follow-up with (2) pre-notification only and (3) follow-up only. The trial was integrated in a survey study among patients, which measured their experiences with general practice cooperatives for out-of-hour care. RESULTS: Of the total number of 880 patients who received the questionnaire, 45% returned it. No significant effect was found of the combination of pre-notification and follow-up compared with the two other arms of the trial. CONCLUSION: Adding pre-notification to follow-up in a patient survey had no additional effect on the response rate. This finding must be interpreted with respect to the questionnaire and the study population.
