“…29 The CSI has established reliability (test-retest above 0.70), internal consistency (alpha above 0.90) and convergent and content validity. 38,39 The GAIN SPS is a 16-item subscale from a comprehensive assessment instrument that measures problems resulting from alcohol and other drug use (including street drugs and nonmedical use of prescription drugs). 30 Response options are: "past month," "2-12 months ago," "1 or more years ago," and "never."…”

Cognitive Interviewing Methods for Questionnaire Pre-Testing in Homeless Persons with Mental Disorders

In this study, cognitive interviewing methods were used to test targeted questionnaire items from a battery of quantitative instruments selected for a large multisite trial of supported housing interventions for homeless individuals with mental disorders. Most of the instruments had no published psychometrics in this population. Participants were 30 homeless adults with mental disorders (including substance use disorders) recruited from service agencies in Vancouver, Winnipeg, and Toronto, Canada. Six interviewers, trained in cognitive interviewing methods and using standard interview schedules, conducted the interviews. Questions and, in some cases, instructions, for testing were selected from existing instruments according to a priori criteria. Items on physical and mental health status, housing quality and living situation, substance use, health and justice system service use, and community integration were tested. The focus of testing was on relevance, comprehension, and recall, and on sensitivity/acceptability for this population. Findings were collated across items by site and conclusions validated by interviewers. There was both variation and similarity of responses for identified topics of interest. With respect to relevance, many items on the questionnaires were not applicable to homeless people. Comprehension varied considerably; thus, both checks on understanding and methods to assist In addition, there are five site coordinators (one for each city where the study is carried out) and numerous lead service and housing providers. CEA is lead for quantitative measurement and data collection at the national level; MLP and KSM are site research coordinators; SWH is lead investigator for the Toronto site; ACH was an undergraduate medical research student for the summer of 2009; and PNG is the national research lead. 36comprehension and recall are recommended, particularly for participants with acute symptoms of mental illness and those with cognitive impairment. The acceptability of items ranged widely across the sample, but findings were consistent with previous literature, which indicates that "how you ask" is as important as "what you ask." Cognitive interviewing methods worked well and elicited information crucial to effective measurement in this unique population. Pretesting study instruments, including standard instruments, for use in special populations such as homeless individuals with mental disorders is important for training interviewers and improving measurement, as well as interpreting findings.

“…The CSI was chosen because, as shown by Boothroyd and Chen (2008), it can be used to discriminate the degree of psychiatric disability amongst a group of SMI individuals. Using a contrasting groups approach with the 14-item CSI (14-70), Boothroyd and Chen (2008) used the distributions of respondents' CSI scores in the ''No known disability'' and the ''Psychiatric disability only'' to derive a Community Ment Health J (2011) 47:672-678 673 cut-off score. Their results recommended 30 as a reasonable clinical cut-off score.…”

“…He also found Cronbach alphas for internal consistency ranging from 0.87 to 0.92 across the eight sites. Boothroyd and Chen (2008) reported an overall Pearson correlation of 0.71 between two administrations of the CSI, with an average time span between administrations of 381 days. Based on these psychometric properties, we believe that using the CSI measurement for a sample of persons with SMI can result in a consistent longitudinal classification in spite of potential intermittent fluctuations in the score.…”

Using Psychiatric Symptomatology to Assess Risk for HIV Infection in Individuals with Severe Mental Illness

In this study, we use the Colorado Symptom Index, a measure of psychiatric symptomatology, to identify vulnerable subgroups within the severely mentally ill population at elevated risk for HIV infection. Baseline data on 228 HIV positive and 281 HIV negative participants from two clinical trials were used. With years to HIV diagnosis as our primary endpoint, Kaplan-Meier estimates were calculated to find a CSI cut-off score, and a Cox proportional hazards model was used to obtain relative risks of infection for the two CSI categories created by the cut point. We found that a CSI score ≥ 30 was associated with a 47% increased risk for HIV infection (P < 0.01). While this study establishes the foundation for using CSI scores to identify a vulnerable subgroup within the SMI community, further studies should develop effective approaches to mitigate psychiatric symptomatology in order to examine the impact on HIV transmission risky behaviors.

“…The modified Colorado Symptom Index (CSI) was used to assess participant mental health symptomatology in the past month (Boothroyd & Chen 2008). Designed specifically for individuals with mental health problems, the CSI is a widely-used research instrument found to have excellent internal consistency (.92) and test-retest reliability (.71).…”

“…This 14-item instrument uses a 5-point Likert scale with answer choices ranging from 0 (not at all) to 4 (at least every day), and a summary score is tabulated (range: 0 to 56, with higher scores indicating greater symptom severity). Scores greater than 30 have been used as a clinical cut-point to identify individuals with mental health service needs (Boothroyd & Chen 2008).…”

Here we describe the rationale for CATCH program development, details of the mixed methods evaluation underway, and the characteristics of 225 CATCH service users.Funded in 2010 by the local health authority, CATCH aimed to improve access, continuity of care, health and service use outcomes for homeless adults discharged from hospital. To assess the feasibility, acceptability and impact of the program, a mixed-methods case study was undertaken in 2013. In total, 225 CATCH program users were enrolled in the study and completed quantitative survey measures at program entry to assess key health and social outcomes using a pre-post cohort study design. Follow-up assessments took place at 3-and 6-months. At study entry, most participants were male (79%), white (65%), Canadian-born (74%), single or never married (60%), and their average age was 39.9 ± 12.0 years. Nearly all participants (88%) had at least one emergency department visit in the past six months, more than half (53%) indicated at least three chronic health conditions, and 44% indicated at least three mental health diagnoses. In addition, qualitative data was collected to evaluate the experiences of continuity of care and challenges during care transitions for this population using in-depth interviews with a sample of CATCH service users (n=22) and managers of partnered organizations (n=7), as well as focus groups with CATCH staff (n=8), other service providers (n=7) and people with lived experience of homelessness (n=8). Improving health and health service use outcomes among homeless adults with chronic health conditions are key priorities in many jurisdictions. Future findings can inform service delivery to homeless adults discharged 2 from hospital, by exposing factors associated with positive program outcomes, as well as barriers and facilitators to continuity of care for this disadvantaged population.
