Objective-This study determined the validity and reliability of a new, abbreviated version of the Spanish Barratt Impulsiveness Scale (BIS-15S) in Colombian subjects. Method-The BIS-15S was tested in non-clinical (n=283) and clinical (n=164) native Spanishspeakers. Intra-scale reliability was calculated using Cronbach's α, and test-retest reliability was measured with Pearson correlations. Psychometric properties were determined using standard statistics. A factor analysis was performed to determine BIS-15S factor structure.Results-447 subjects participated in the study. Clinical subjects were older and more educated compared to non-clinical subjects. Impulsivity scores were normally distributed in each group. BIS-15S total, motor, non-planning and attention scores were significantly lower in non-clinical vs. clinical subjects. Subjects with substance-related disorders had the highest BIS-15S total scores, followed by subjects with bipolar disorders and bulimia nervosa/binge eating. Internal consistency was 0.793 and test-retest reliability was 0.80. Factor analysis confirmed a three-factor structure (attention, motor, non-planning) accounting for 47.87% of the total variance in BIS-15S total scores.Conclusions-The BIS-15S is a valid and reliable self-report measure of impulsivity in this population. Further research is needed to determine additional components of impulsivity not investigated by this measure.

Spatial agglomeration is a central aspect of human life and of the geographic space in which most economic and social exchanges take place (Bairoch 1988). The size and shape of this geographic space have key implications for policy design, as they affect the regular patterns of mobility and interactions of people, goods, and ideas. This functional reality is weakly captured by the usual political-administrative units. Functional territories, as we call them in this study, represent a complex socio-spatial picture of overlapping markets between "areas or locational entities which have more interaction or connection with each other than with outside areas" (Brown and Holmes 1971, p 57), and with high frequency of economic and social interactions between their inhabitants, organizations, and firms (Berdegué et al. 2011).

Background Severe mental illness (SMI) presents a major burden to societies worldwide. Low- and middle-income countries (LMICs) often do not have sufficient financial resources and qualified staff to provide extensive specialised services for outpatients with SMI. Our research therefore aims to explore and test low-cost interventions that use existing resources in routine patient-clinician meetings, families and communities. Methods In Bosnia-Herzegovina, Colombia and Uganda, three psychosocial interventions will be tested, i.e. making patient-clinician meetings therapeutically effective through DIALOG+, family involvement in multi-family group meetings, and support for patients in befriending schemes with volunteers. All interventions will be provided to patients with SMI, delivered over a six-month period and evaluated with assessments at baseline and after six and 12 months. We will conduct nine trials including non-controlled trials, non-randomised controlled trials and randomised controlled trials (RCTs). Core outcome criteria will be used across all studies. However, details of study delivery and additional outcome criteria vary to accommodate local contexts, interests and priorities. The studies will be analysed separately, but with the option to compare and combine findings. Discussion The approach provides the opportunity to learn from commonalities and differences in the results and experiences across the three resource-oriented approaches and the three countries. If successfully implemented the studies can lead to more extensive research and are expected to inform health policies and clinical practice of community care for patients with SMI in the three participating countries and other LMICs. Trial registration All RCTs were registered prospectively and non-randomised trials retrospectively within the ISRCTN Registry.
