Enhancing validity in co-occurring disorders treatment research.

Despite the high prevalence of co-occurring mental health and substance-use disorders, there has been a relative lack of treatment research with this population, and the existing research often has limited validity. This article explores some of the barriers to the conduct of research on promising interventions for substance-abuse treatment for people with co-occurring disorders, using the concepts of external and ecological validity to make recommendations for future investigation. The central recommendation is to move rapidly from efficacy studies to more credible and valid effectiveness studies, in order to facilitate the adoption of evidence-based interventions in routine practice settings.

Conduct disorder and antisocial personality disorder in persons with severe psychiatric and substance use disorders.

Conduct disorder (CD) and antisocial personality disorder (ASPD) are established risk factors for substance use disorders in both the general population and among persons with schizophrenia and other severe mental illnesses. Among clients with substance use disorders in the general population, CD and ASPD are associated with more severe problems and criminal justice involvement, but little research has examined their correlates in clients with dual disorders. To address this question, we compared the demographic, substance abuse, clinical, homelessness, sexual risk, and criminal justice characteristics of 178 dual disorder clients living in 2 urban areas between 4 groups: No CD/ASPD, CD Only, Adult ASPD Only, and Full ASPD. Clients in the Adult ASPD Only group tended to have the most severe drug abuse severity, the most extensive homelessness, and the most lifetime sexual partners, followed by the Full ASPD group, compared with the other 2 groups. However, clients with Full ASPD had the most criminal justice involvement, especially with respect to violent charges and convictions. The results suggest that a late-onset ASPD subtype may develop in clients with severe mental illness secondary to substance abuse, but that much criminal behavior in clients with dual disorders may be due to the early onset of the full ASPD syndrome in this population and not the effects of substance use disorders.

Effectiveness of switching antipsychotic medications.

OBJECTIVE: Changing antipsychotics is common despite the dearth of information on risks and benefits associated with medication changes. The authors examined phase 1 findings from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study to explore whether it was more advantageous to continue taking the medication being received at baseline or to switch to a different antipsychotic. METHOD: First, for patients randomly assigned to treatment with olanzapine (N=314) or risperidone (N=321), the authors assessed the impact of being assigned to stay with the medication they were receiving at entry into the study versus being assigned to switch to these medications from a different antipsychotic. Second, for patients whose baseline antipsychotic was olanzapine (N=319), risperidone (N=271), or quetiapine (N=94), the authors examined the impact of being randomly assigned to stay with the same antipsychotic versus switch. Finally, the authors assessed the impact of removing the data of 209 patients whose random assignment was to stay with their baseline antipsychotic. The authors followed analysis strategies for CATIE; primary outcome was time until all-cause treatment discontinuation. RESULTS: Individuals randomly assigned to olanzapine and risperidone who were continuing with their baseline medication had significantly longer times until discontinuation than did those assigned to switch antipsychotics. When these "stayers" were removed, differences seen in the original CATIE phase 1 analyses were attenuated, although the original pattern of results remained. CONCLUSIONS: Comparisons of medication effectiveness should take into account whether medications being compared were each newly initiated. Further, unless the clinical situation requires a medication change, prescribers may want to take steps to optimize current medication regimens (e.g., dosage adjustments, behavioral or psychosocial interventions) before switching medications.

Comparison of ACT and standard case management for delivering integrated treatment for co-occurring disorders.

OBJECTIVE: Clients with co-occurring severe mental and substance use disorders are at high risk of institutionalization and other adverse outcomes. Although integrated mental health and substance abuse treatment is becoming a standard clinical approach for such clients, the optimal method for delivering integrated treatment remains unclear. METHOD: This study compared integrated treatment delivered within two different models of community-based case management (assertive community treatment and standard clinical case management). A total of 198 clients in two urban sites who had co-occurring disorders and were homeless or unstably housed were randomly assigned to one of two treatment conditions and were followed for three years. RESULTS: Participants in both treatment conditions improved over time in multiple outcome domains, and few differences were found between the two models. Decreases in substance use were greater than would be expected given time alone. At the site that had higher rates of institutionalization, clients who received standard case management were more likely to be institutionalized. However, in the site that had lower rates of institutionalization, no differences in the rate of institutionalization were found between the two treatment conditions. CONCLUSIONS: Integrated treatment can be successfully delivered either by assertive community treatment or by standard clinical case management.

Demographic characteristics of individuals who received Project Liberty crisis counseling services.

OBJECTIVES: This article describes demographic characteristics of service recipients and their patterns of use of crisis counseling services provided under Project Liberty during the 27 months after the September 11, 2001, attacks on the World Trade Center. It also examines the extent to which service recipients reflected the demographic characteristics of their home communities. METHODS: A total of 753,015 service encounter logs submitted by 177 providers were analyzed to determine rates of use by different demographic groups and to evaluate patterns of use over time with goodness-of-fit and logistic regression models. RESULTS: A total of 687,848 individual crisis counseling sessions were provided to an estimated 465,428 individuals, including large numbers of persons from racial or ethnic minority groups and non-English-speaking individuals. Most of these services were provided to residents of the five New York City boroughs, with a small percentage of services to residents from the ten surrounding counties. Most services were provided in community settings rather than provider offices. African-American and Hispanic individuals showed the greatest increase in rates of accessing services over time. Follow-up visits were significantly more likely to be by Caucasians than by non-Caucasians, and children were more likely than adults to receive follow-up visits. Demographic characteristics of individuals using Project Liberty crisis counseling services generally were representative of the five boroughs and ten other counties constituting the greater metropolitan region and representative of estimated need. CONCLUSIONS: Project Liberty provided services that were accessible to individuals of diverse racial and ethnic backgrounds.

Use of Project Liberty counseling services over time by individuals in various risk categories.

OBJECTIVE: The authors examined temporal changes in the rates at which people sought access to Project Liberty services after the attacks of September 11, 2001, according to risk category (family of missing or deceased, persons directly affected, uniformed personnel, other rescue or recovery workers, schoolchildren, displaced employed and unemployed workers, persons with disabilities, and the general population). METHODS: First visits to individual counseling services, as determined from logs of 465,428 service encounters, were proportioned among risk categories and plotted across 27 months. RESULTS: Individuals who lost family members accounted for 40 percent of visits in the first month but dropped to 5 percent or fewer visits by five months. Uniformed personnel used disproportionately larger percentages of services after the first year. Occupationally displaced and unemployed workers sought counseling at relatively steady rates. CONCLUSIONS: Postdisaster counseling should be made available for extended periods, with shifting emphases to meet the changing needs of high-risk groups.

Clusters of event reactions among recipients of Project Liberty mental health counseling.

OBJECTIVE: This study aimed to determine a pattern in the frequency with which individuals who manifested distress reactions resembling diagnostic syndromes of posttraumatic stress disorder (PTSD) and major depressive disorder accessed services provided by Project Liberty. METHODS: Hierarchical cluster analysis was applied to 31 reactions to stress (event reactions) shown by 465,428 recipients of Project Liberty counseling, to determine how well event reactions mapped onto traditional diagnostic criteria. Service recipients were tracked when they first sought Project Liberty counseling during the 27 months after the attacks. Those who reported three or more reactions associated with these clusters were characterized as having possible diagnosable conditions. RESULTS: Strong consistent clusters corresponding to traumatic stress and depressive symptoms emerged, with 26 percent, 16 percent, and 8 percent of service recipients rated as having possible PTSD, major depressive disorder, or both, respectively. Taken together, this group constituted over 40 percent of service recipients served by Project Liberty almost every month throughout the 27 months of its existence. CONCLUSIONS: Event reactions, as reported by Project Liberty crisis counselors, many of whom were nonclinicians, mapped coherently onto diagnostic syndromes, suggesting that a checklist of such reactions may be useful to disaster counselors as a cost-effective screening and planning instrument. The steady entry over time into Project Liberty counseling by a substantial number of individuals experiencing high levels of distress underscores the need for providing long-term access to mental health services postdisaster.

Service utilization and event reaction patterns among children who received Project Liberty counseling services.

OBJECTIVES: This study examined service utilization and event reaction patterns among children who used crisis counseling services provided under Project Liberty for 27 months after the September 11, 2001, terrorist attacks on the World Trade Center. METHODS: The authors analyzed logs of 681,318 service encounters submitted by Project Liberty counselors, paying particular attention to demographic characteristics and reported event reactions. RESULTS: Nine percent of service recipients reached by community-based Project Liberty providers were children, whereas census data for the 15 counties and boroughs served by Project Liberty indicated that children constituted 25 percent of the population. Service use as a function of race or ethnicity and of gender was consistent with census data. Similar to findings for adults, the most common emotional event reactions reported for children were experiencing sadness and tearfulness, being anxious and fearful, having difficulty concentrating, experiencing irritability and anger, having intrusive thoughts or images, and having difficulty sleeping. Behavioral event reactions listed on service logs suggested that older children (12 to 17 years) were more likely to use drugs whereas elementary school-age children were more likely to display signs of anxiety, isolation and withdrawal, and difficulties with concentration and memory. CONCLUSIONS: Sensitivity to differences in the event reaction patterns shown by younger and older children may be useful in refining treatments to help reduce the psychological impact of children's trauma after terrorist incidents.

The road back: predictors of regaining preattack functioning among Project Liberty clients.

OBJECTIVES: This study determined the likelihood and predictors of Project Liberty counseling recipients' reporting their return to satisfactory life functioning 16 to 26 months after the September 11, 2001, attacks. METHODS: Using anonymous brief paper-and-pencil questionnaires or structured telephone interviews, 452 respondents provided retrospective ratings of their functioning in five life domains during the month before the World Trade Center attacks and the month immediately before the assessment. Information on demographic characteristics and exposure to risk during the World Trade Center attacks also was obtained and used in logistic regression models. The 153 respondents who were interviewed by telephone also rated helpfulness of various coping strategies. RESULTS: In the five domains, 77 to 87 percent of the sample reported good to excellent functioning in the month before the attacks; 55 to 68 percent reported returning to at least the same level of daily functioning after the attacks. African Americans were two to four times more likely than respondents of all other races to report a return to good or excellent functioning after the attack in four domains. Compared with respondents who did not lose their job as a result of the attacks, those who did lose their job were less likely to return to good preattack functioning in two domains. Project Liberty counseling reportedly helped 90 percent of respondents return to predisaster levels of functioning. CONCLUSIONS: Responses to future terrorist attacks should consider demographic characteristics and the impact of the attack because they can affect return to preattack functioning. Counselors should support activities that facilitate positive responses and ameliorate negative psychological responses.

Screening for complicated grief among Project Liberty service recipients 18 months after September 11, 2001.

OBJECTIVE: The authors surveyed a sample of Project Liberty crisis counseling recipients approximately 1.5 years after the terrorist attacks on September 11, 2001, to determine the proportion of respondents who screened positive for complicated grief, a recently identified condition marked by symptoms of continuing separation distress and accompanying bereavement-related traumatic distress. METHODS: A total of 149 service recipients drawn from eight high-volume providers responded to a telephone survey that included questions to screen for complicated grief. RESULTS: Approximately half of the recipients knew someone who had been killed in the attacks. Of those recipients, 44 percent screened positive for complicated grief. Individuals who lost a family member were more likely than those who lost an acquaintance to screen positive for complicated grief. Positive screens were associated with functional impairment independent of the presence of symptoms consistent with full or subthreshold major depression or posttraumatic stress disorder (PTSD). Thirty-two percent of those who screened positive for complicated grief did not meet even subthreshold criteria for major depression or PTSD. CONCLUSIONS: Results affirmed the importance of complicated grief as a unique condition and indicated the need to attend to the psychological consequences of bereavement in disaster-related mental health services.

Outcomes of enhanced counseling services provided to adults through Project Liberty.

OBJECTIVE: Project Liberty provided brief crisis counseling to 753,015 residents of New York City and surrounding counties after the attacks on the World Trade Center. Most regained predisaster functioning after counseling. For those who did not, Project Liberty provided enhanced services by specially trained, licensed mental health professionals. Individuals receiving crisis counseling and enhanced services responded to confidential telephone interviews about 18 and 24 months, respectively, after the attacks. Impairment was compared between groups to determine whether enhanced services recipients reported improved functioning and fewer symptoms of depression, posttraumatic stress, and complicated grief. METHODS: Crisis counseling recipients (N=153) were interviewed once and enhanced services recipients (N=76) were interviewed twice about symptomatology and daily functioning. RESULTS: The samples did not differ in age or gender. Significantly greater proportions of enhanced services recipients reported knowing someone who died as a result of the attacks, having been involved in rescue efforts, or having lost their job because of the attacks. Compared with crisis counseling respondents, enhanced services recipients at their first interview reported significantly more symptoms of depression, grief, and traumatic stress and significantly poorer daily functioning in five life areas. At follow-up, enhanced services respondents reported significant improvement in three of five functioning domains, significantly fewer symptoms of depression and grief, and marginally less traumatic stress. CONCLUSIONS: Recipients of enhanced services were more impaired than people who received only crisis counseling. On the basis of reports from service recipients, meaningful improvements in functioning and symptoms may be associated with the receipt of enhanced services.

Impact of a media campaign for disaster mental health counseling in post-September 11 New York.

OBJECTIVE: After the September 11, 2001, terrorist attacks on the World Trade Center, the New York State Office of Mental Health (NYOMH) initiated a three-phase multifaceted, multilingual media campaign that advertised the availability of counseling services. This study evaluated the association between patterns of spending within this campaign and the volume of calls received and referred to a counseling program. METHODS: Spending on television, radio, print, and other advertising was examined, as was the corresponding volume of calls to the NetLife hotline seeking referrals to counseling services. RESULTS: From September 2001 to December 2002, $9.38 million was spent on Project Liberty media campaigns. Call volumes increased during months when total monthly expenditures peaked. Initially, flyers, billboards, and other material items accounted for most monthly expenses. Over time, spending for television and radio advertisements increased, whereas other advertising declined. Temporal patterns show that in periods after an increase in media spending, call volumes increased independently of other sentinel events such as the one-year anniversary of the attacks. CONCLUSIONS: Sustained advertising through multiple media outlets appeared to be effective in encouraging individuals to seek mental health services.

Did Project Liberty displace community-based medicaid services in New York?

OBJECTIVE: This study analyzed how the introduction of Project Liberty services after the September 11, 2001, terrorist attacks affected agencies' provision of community-based Medicaid mental health services in the New York metropolitan area. METHODS: Provision of Medicaid mental health services was tracked between January 2000 and June 2003 for provider agencies participating in Project Liberty (N=164) and for a comparison group of mental health provider agencies that did not participate in this program (N=94). RESULTS: Overall, participation in Project Liberty did not significantly affect the volume of Medicaid services provided. However, for agencies with one site, a statistically significant difference was seen; compared with agencies in the comparison group, agencies that participated in Project Liberty claimed a mean+/-SE decrease of $4.66+/-3.57 less in Medicaid services per month per Project Liberty visit. CONCLUSIONS: Project Liberty permitted rapid expansion of the total volume of services provided by community-based organizations without interfering with the provision of traditional services, although a modest effect was seen for smaller agencies. Although the results do not imply that "supply side" planning for disaster needs would not improve system response, they do imply that implementation of flexible "demand side" financing can call forth a large volume of new services rapidly and without interfering with other community services.

Characteristics of Project Liberty clients that predicted referrals to intensive mental health services.

OBJECTIVE: The authors describe characteristics of Project Liberty crisis counseling recipients that predicted referral to more intensive professional mental health treatments over the two-year period after the terrorist attacks on the World Trade Center. METHODS: Random-effects ordinal regression models were applied to data from 684,500 logs of Project Liberty service encounters for individual counseling sessions. RESULTS: Overall, about 9 percent of individual counseling visits ended with a referral to professional mental health services. Individuals needing intensive mental health treatment continued to enter Project Liberty for two years after the World Trade Center attacks. The strongest predictor of referral was having reactions to the attack that fell into a greater number of the four domains assessed-behavioral, emotional, physical, or cognitive domains. Individuals with reactions in four domains were most likely to be referred. Those who had greater attack-related exposure were also more likely to be referred. CONCLUSIONS: It is important to provide long-term access to brief counseling and triage services and to target these interventions specifically to individuals displaying greater distress or impairment and having more traumatic exposure.
