In a prospective cohort study of consecutive primary care attenders in south London, the estimated prevalence of non-psychotic psychiatric disorder was 45.6%, using the Revised Clinical Interview Schedule (CIS-R). The estimated 12-month incidence rate was 15.7%. Extremely high stability was found in CIS-R scores over 12 months (r = 0.65) and 68.8% of cases at baseline were also cases 12 months later. A clear difference emerged in the types of risk factor which were associated with the incidence and maintenance of disorder in the study population: while socio-economic variables, especially low household income and not having a partner were associated with a worse outcome among prevalent cases at baseline, such variables were only weakly associated with the incidence of psychiatric disorder after adjusting for potential confounders. The latter, notably family psychiatric history and the severity of psychiatric symptoms at baseline were independently associated with the incidence of psychiatric disorder after adjusting for other risk factors, including measures of previous psychiatric disorder.

Objective:The objective of this study was to investigate the feasibility and acceptability of a multi-component mobile contingency management (CM) pilot intervention for smoking cessation for people with schizophrenia.Methods: This intervention included mobile contingency management (i.e., monetary compensation for bioverification of abstinence through using a phone app), cognitive behavioral therapy (CBT), and pharmacotherapy for smoking cessation. This intervention was compared to an intensive treatment comparison (ITC), which contained all components except the CM. Participants were bioverified with carbon monoxide and saliva cotinine at a 6-month follow-up session. Results:In this pilot, the treatment group did not differ from the intensive treatment comparison at any time point. However, measures of treatment feasibility and acceptability indicated that smokers with schizophrenia were able to navigate the CM phone application and adhere to the protocol, demonstrating the potential utility of mobile interventions in this population.Conclusions: Despite lack of long-term abstinence for participants, adherence to the mobile application intervention indicates the potential for future investigation of mobile smoking cessation treatments for people with schizophrenia.
