Development of a comprehensive measure to assess clinical issues in dual diagnosis patients: The Substance Use Event Survey for Severe Mental Illness

The reliability and validity of the Maryland Assessment of Recovery in Serious Mental Illness Scale

The current study aims to further evaluate the psychometric properties of the Maryland Assessment of Recovery in Serious Mental Illness (MARS), a relatively new instrument designed to assess personal recovery status in individuals with serious mental illness. Two hundred and fifty individuals with serious mental illness receiving outpatient mental health treatment completed a baseline assessment which included the MARS and measures to assess recovery-related constructs, clinical outcomes, and social and community functioning. The MARS demonstrated excellent internal consistency and test-retest reliability. Good construct validity was evidenced by strong positive relationships between the MARS and recovery-related constructs (e.g. hope, empowerment, self-efficacy, and personal agency) and a strong negative relationship with self-stigma. Divergent validity was demonstrated by weaker relationships with cognitive and social functioning. The confirmatory factor analysis did not confirm the unitary factor structure found in previous research. Given the equivocal result of the CFA, additional exploratory work is needed to determine if a more complex factor structure is present. This study provides addition support for the psychometric soundness of the MARS and subsequently, its potential use as a measure of personal recovery status in people with serious mental illness.

Co-occurring psychotic and addictive disorders: neurobiology and diagnosis

Psychosis and substance abuse are intimately related. Psychotic spectrum illnesses commonly co-occur with substance use disorders (SUDs), and many substances of abuse can cause or exacerbate psychotic symptoms along a temporal spectrum from acute to chronic presentations. Despite the common co-occurrence between psychotic spectrum illnesses and SUDs, they are often under-recognized and undertreated, leading to poor treatment outcomes. Accurate detection and diagnosis of individuals with psychotic illness co-occurring with addictive disorders is key to properly treat such disorders. This article will review the nature of the relationship between psychosis and substance abuse by examining prevalence rates of each disorder alone and their rates of co-occurrence, the neurobiological basis for substance abuse comorbidity in schizophrenia spectrum disorders, key and salient aspects related to accurate diagnosis along a continuum from acute to subacute to chronic conditions, and pitfalls associated with diagnostic dilemmas. A case example will be used to highlight key points related to diagnostic challenges.

Impact of Family History in Persons With Dual Diagnosis

OBJECTIVE

This study examined relationships among family history of alcohol, drug, and psychiatric problems and substance use severity, interpersonal relationships, and service use in individuals with dual diagnosis.

METHODS

Data were collected with the family history section of the Addiction Severity Index administered as part of three studies of individuals with dual disorders (N=413). Participants were categorized into family history risk groups for each problem domain based on the number of first and second degree relatives with alcohol, drug, or psychiatric problems.

RESULTS

Rates of alcohol, drug, and psychiatric problems were high across family member categories and highest overall for siblings. Over two-thirds of the sample was categorized in the high-risk group in the alcohol problem domain, almost half of the sample was categorized as high-risk in the drug problem domain, and over a third of the sample was categorized as high-risk in the psychiatric problem domain. Across problem domains, individuals in the high-risk group reported more relationship problems with parents and siblings and higher rates of lifetime emotional, physical, and sexual abuse than did those in the low or moderate-risk groups.

CONCLUSIONS

Family history of alcohol, drug, and psychiatric problems is associated with greater rates of poor family relationships and history of abuse. Assessment of these different forms of family history in multiple family members can aid treatment providers in identifying individuals with dual disorders who may benefit from trauma-informed care as part of their overall mental health and substance abuse treatment services.

Patterns and Predictors of Changes in Substance Use in Individuals with Schizophrenia and Affective Disorders

OBJECTIVE: This study examined patterns and predictors of changes in substance use over one year in individuals with schizophrenia and affective disorders. We examined patterns of cocaine use over time, baseline predictors of continued cocaine use over one year, and predictors of transitions into and out of drug use and treatment. METHODS: We recruited 240 individuals with schizophrenia and affective disorders who met DSM-IV criteria for current cocaine dependence or cocaine dependence in early full or sustained full remission, and assessed them five times over twelve months. RESULTS: There was no change over time in either the proportion of the sample with at least one day of cocaine use in the past month or in the average number of days of cocaine use among those who reported any use. Baseline variables tapping actual substance use were found to predict a decreased likelihood of cocaine use. Several variables tapping actual substance use - including self- reported use of cocaine, positive urinalysis for marijuana, and positive urinalysis for cocaine - were predictive of transitions into and out of outpatient substance abuse treatment. Readiness to change variables such as self-efficacy and temptation to use drugs showed different predictive patterns for the schizophrenia and affective disorder groups. CONCLUSIONS: These findings illustrate how drug use may show a cyclical pattern for those with serious mental illness, in which more severe use - characterized by greater frequency of use and associated problems - is followed by decreased use over time.

Gender differences in substance use, consequences, motivation to change, and treatment seeking in people with serious mental illness

Gender differences in patterns and consequences of substance use, treatment-seeking, and motivation to change were examined in two samples of people with serious mental illness (SMI) and comorbid substance use disorders (SUDs): a community sample not currently seeking substance abuse treatment (N = 175) and a treatment-seeking sample (N = 137). In both groups, women and men demonstrated more similarities in the pattern and severity of their substance use than differences. However, treatment-seeking women showed greater readiness to change their substance use. Mental health problems and traumatic experiences may prompt people with SMI and SUD to enter substance abuse treatment, regardless of gender.

Advisor-Teller Money Manager (ATM) therapy for substance use disorders

OBJECTIVE

Patients with concomitant psychiatric and substance use disorders are commonly assigned representative payees or case managers to help manage their funds, but money management has not been conceptualized as a theory-based treatment. This randomized clinical trial was conducted to determine the effect of a money management-based therapy, advisor-teller money manager (ATM), on substance abuse or dependence.

METHODS

Ninety patients at a community mental health center who had a history of cocaine or alcohol abuse or dependence were assessed after random assignment to 36 weeks of ATM (N=47) or a control condition in which use of a financial workbook was reviewed (N=43). Patients assigned to ATM were encouraged to deposit their funds into a third-party account, plan weekly expenditures, and negotiate monthly budgets. Substance use calendars and urine toxicology tests were collected every other week for 36 weeks and again 52 weeks after randomization.

RESULTS

Patients assigned to ATM had significantly more negative toxicologies for cocaine metabolite over time than patients in the control group, and treating clinicians rated ATM patients as significantly more likely to be abstinent from illicit drugs. Self-reported abstinence from alcohol did not significantly differ between groups. Unexpectedly, patients assigned to ATM were more likely to be assigned a representative payee or a conservator than control participants during the follow-up period (ten of 47 versus two of 43). One patient in ATM assaulted the therapist when his check had not arrived.

CONCLUSIONS

ATM is an efficacious therapy for the treatment of cocaine abuse or dependence among people with concomitant psychiatric illness but requires protection of patient autonomy and staff safety.

Substance dependence and remission in schizophrenia: A comparison of schizophrenia and affective disorders

The present study examined psychiatric functioning, substance use and consequences, and motivation to change in people with schizophrenia and affective disorders and current or remitted cocaine dependence. Data were collected as part of a naturalistic, longitudinal study examining substance use, motivation to change, and the process of change in people with schizophrenia and affective disorders who were currently dependent or in remission from cocaine dependence. We examined the following questions: (1) Do those in remission show better psychiatric functioning than those who are currently dependent? (2) How do people with schizophrenia and current cocaine dependence differ in terms of substance use and consequences from people with schizophrenia in remission and people with affective disorders and current drug dependence? (3) What internal factors and external factors are associated with changes in substance use in schizophrenia and how do these compare to those in nonpsychotic affective disorders? Results indicated that people with schizophrenia and current dependence reported higher levels of positive and negative symptoms than those in remission. Remission status was related to less use of other drugs, fewer days of drug problems, less distress from drug problems, and more lifetime drug-related consequences. Those with current dependence reported more days of drinking and drinking to intoxication, as well as higher rates of current alcohol use disorders than the remitted group. When compared to those with affective disorders and cocaine dependence, those with schizophrenia and current dependence reported fewer days of problems associated with their drug use, less distress from drug problems, and fewer recent and lifetime consequences associated with their drug use. The schizophrenia dependent group generally showed the lowest readiness to change, fewest efforts being made to change, and lowest confidence in the ability to change. Implications of these findings are discussed.

A literature review to assess the reliability and validity of measures appropriate for use in research to evaluate the efficacy of a brief harm reduction strategy in reducing cannabis use among people with schizophrenia in acute inpatient settings

There is a growing body of evidence looking at the effects of cannabis use on those with schizophrenia with concerning results. This has led to the development of a number of interventions that are intended to improve outcomes for this client group. However, the methodological quality of some dual diagnosis research has been questioned in reviews for using outcome measures that are not tested as reliable and valid in the population for which they are intended for use. This literature review assesses the self-report measures that have been reliability and validity tested in populations of people with schizophrenia who use cannabis and reports on their appropriateness for use in further research studies. An overview of the most appropriate biochemical tests for cannabis is also given.

Predictors of cannabis use in men with and without psychosis

BACKGROUND

Factors associated with cannabis use among people with psychosis are not well understood.

AIMS

To examine whether people with psychosis and age-matched controls modified cannabis use in response to recent experiences.

METHOD

This study predicted 4 weeks of cannabis use prospectively, using expectancies derived from recent occasions of use.

RESULTS

People with psychosis used cannabis less frequently than controls, but had more cannabis-related problems. More negative cannabis expectancies resulted in less frequent cannabis use over Follow-up. The psychosis group was more likely to moderate cannabis use after negative effects than controls.

CONCLUSIONS

Results offer optimism about abilities of people with psychosis to moderate cannabis use in the short term.

Reinstitutionalization following psychiatric discharge among VA patients with serious mental illness: a national longitudinal study

Patterns of reinstitutionalization following psychiatric hospitalization for individuals with serious mental illnesses (SMI) vary by medical and psychiatric health care settings. This report presents rates of reinstitutionalization across care settings for 35,527 patients following psychiatric discharge in the Department of Veterans Affairs (VA) health system, a national health care system. Over a 7-year follow-up period, 30,417 patients (86%) were reinstitutionalized. Among these patients, 73% were initially reinstitutionalized to inpatient psychiatric settings. Homelessness, medical morbidity, and substance use were associated with increased risks for reinstitutionalization. Despite the VA's increased emphasis on outpatient services delivery, the vast majority of patients experienced reinstitutionalization in the follow-up period. Study findings may inform efforts to refine psychiatric and medical assessment for service delivery for this vulnerable population.

Assessment of motivation to change substance use in dually-diagnosed schizophrenia patients

Assessment of motivation to change substance use can be helpful in evaluating treatment readiness and outcome. However, the utility of self-report measures of motivation with schizophrenia patients is questionable. In the current study patients with schizophrenia and either concurrent cocaine dependence or remitted dependence completed the University of Rhode Island Change Assessment-Maryland (URICA-M), a self-report inventory that assesses motivation, and an analogous cartoon instrument at baseline and 6-months follow-up. Results demonstrate that the cartoon readiness to change score was related to increased treatment utilization and decreased substance use; results were not as favorable for the URICA-M. Findings suggest that the cartoon measure may be a suitable alternative to assess motivation to change substance use with cognitively impaired patients.
