Preliminary needs assessment of mobile technology use for healthcare among homeless veterans

Background. Homeless veterans have complex healthcare needs, but experience many barriers to treatment engagement. While information technologies (IT), especially mobile phones, are used to engage patients in care, little is known about homeless veterans\u27 IT use. This study examines homeless veterans\u27 access to and use of IT, attitudes toward health-related IT use, and barriers to IT in the context of homelessness. Methods. Qualitative interviews were conducted with 30 homeless veterans in different housing programs in Boston, MA, ranging from emergency shelters to supportive transitional housing that allow stays of up to 2 years. Interviews were conducted in person, audio recorded and then transcribed. Three researchers coded transcripts. Inductive thematic analysis was used. Results. Most participants (90%) had a mobile phone and were receptive to IT use for health-related communications. A common difficulty communicating with providers was the lack of a stable mailing address. Some participants were using mobile phones to stay in touch with providers. Participants felt mobile-phone calls or text messages could be used to remind patients of appointments, prescription refills, medication taking, and returning for laboratory results. Mobile phone text messaging was seen as convenient, and helped participants stay organized because necessary information was saved in text messages. Some reported concerns about the costs associated with mobile phone use (calls and texting), the potential to be annoyed by too many text messages, and not knowing how to use text messaging. Conclusion. Homeless veterans use IT and welcome its use for health-related purposes. Technology-assisted outreach among this population may lead to improved engagement in care

A brief community linkage intervention for veterans with a persistent mental illness and a co-occurring substance abuse disorder

Objective: Individuals with co-occurring psychiatric and substance abuse problems often exhibit poor outpatient treatment engagement and re-hospitalization following discharge from acute psychiatric services. Although case management can improve treatment engagement and reduce attrition, these services are often delivered indefinitely, limiting the availability of treatment slots. In an effort to reduce re-hospitalization rates and improve outcomes during the transition from inpatient to outpatient treatment, we developed and evaluated Time-Limited Case Management (TLC), an eight-week integrated mental health and substance abuse augmentation intervention. Method: Sixty-five dually diagnosed veterans admitted to inpatient psychiatric treatment were included in the program evaluation, 32 who received the TLC service in addition to Treatment as Usual (TAU) that began during inpatient treatment and continued after the transition to outpatient services, and a comparison group of 33 who received only TAU without transitional support provided through the TLC augmentation service. Results: The TLC group had fewer days and episodes of hospitalization at two and six month post-study entry. Furthermore, the TLC group exhibited greater improvements on the Global Assessment of Functioning from baseline to the six-month follow-up. Conclusion: TLC appears to be an effective transitional augmentation service with benefits that persist beyond the eight weeks of the program. Future research should include a larger and more rigorously controlled trial to confirm the efficacy and unique contributions of the intervention

Evidence for Habitual and Goal-Directed Behavior Following Devaluation of Cocaine: A Multifaceted Interpretation of Relapse

BACKGROUND:Cocaine addiction is characterized as a chronically relapsing disorder. It is believed that cues present during self-administration become learned and increase the probability that relapse will occur when they are confronted during abstinence. However, the way in which relapse-inducing cues are interpreted by the user has remained elusive. Recent theories of addiction posit that relapse-inducing cues cause relapse habitually or automatically, bypassing processing information related to the consequences of relapse. Alternatively, other theories hypothesize that relapse-inducing cues produce an expectation of the drug's consequences, designated as goal-directed relapse. Discrete discriminative stimuli signaling the availability of cocaine produce robust cue-induced responding after thirty days of abstinence. However, it is not known whether cue-induced responding is a goal-directed action or habit. METHODOLOGY/PRINCIPAL FINDINGS:We tested whether cue-induced responding is a goal-directed action or habit by explicitly pairing or unpairing cocaine with LiCl-induced sickness (n = 7/group), thereby decreasing or not altering the value of cocaine, respectively. Following thirty days of abstinence, no difference in responding between groups was found when animals were reintroduced to the self-administration environment alone, indicating habitual behavior. However, upon discriminative stimulus presentations, cocaine-sickness paired animals exhibited decreased cue-induced responding relative to unpaired controls, indicating goal-directed behavior. In spite of the difference between groups revealed during abstinent testing, no differences were found between groups when animals were under the influence of cocaine. CONCLUSIONS/SIGNIFICANCE:Unexpectedly, both habitual and goal-directed responding occurred during abstinent testing. Furthermore, habitual or goal-directed responding may have been induced by cues that differed in their correlation with the cocaine infusion. Non-discriminative stimulus cues were weak correlates of the infusion, which failed to evoke a representation of the value of cocaine and led to habitual behavior. However, the discriminative stimulus-nearly perfectly correlated with the infusion-likely evoked a representation of the value of the infusion and led to goal-directed behavior. These data indicate that abstinent cue-induced responding is multifaceted, dynamically engendering habitual or goal-directed behavior. Moreover, since goal-directed behavior terminated habitual behavior during testing, therapeutic approaches aimed at reducing the perceived value of cocaine in addicted individuals may reduce the capacity of cues to induce relapse

The validity and reliability of a brief measure of cocaine craving

INTRODUCTION: Although craving plays an important role in relapse, there are few brief, valid and reliable instruments to measure the desire to use cocaine in routine clinical practice. The 45-item Cocaine Craving Questionnaire-Now (CCQ-Now) is widely used in research, but its length makes its use in everyday clinical work relatively impractical. This study sought to determine the psychometric properties of the CCQ-Brief, a measure composed of 10 items from the CCQ-Now, in treatment-seeking cocaine abusers. METHOD: Subjects with cocaine abuse or dependence (n=247) completed the CCQ-Brief, the CCQ-Now, the Voris Cocaine Craving Scale, the Beck Depression Inventory-II, the Beck Anxiety Inventory, and the Addiction Severity Index. RESULTS: The CCQ-Brief was significantly correlated with the CCQ-Now (r=.85, p\u3c.01), the CCQ-Now with the items in common with the CCQ-Brief removed (r=.78, p\u3c.01), all four subscales of the VCCS (craving intensity: r=.47, p\u3c.01; mood: r=.27, p\u3c.01; energy: r=.30, p\u3c.01; sick feelings: r=.28, p\u3c.01), the BDI-II (r=.39, p\u3c.01), the BAI (r=.35, p\u3c.01) and recent drug use (r=.26, p\u3c.01). The internal consistency of the CCQ-Brief was strong (alpha=.90). DISCUSSION: The CCQ-Brief is a valid and reliable instrument that can be easily administered as a measure of current cocaine craving
