The present study examined Social Control processes in drug cessation among adults. Social Control theory posits that the association between drug use and the drug use of a person's social network results from an individual seeking out similar peers. The data included 629 individuals who reported past-year heroin or cocaine use at baseline and had follow-up data in a community study in Baltimore, MD. Negative binomial regression modeling indicated that the reduction in social network drug use was significantly greater for quitters than those who did not quit. Compared to non-quitters at baseline, the IRR of the number of drug-using network members was 0.86 for quitters at baseline, 0.71 for non-quitters at follow-up, and 0.28 for quitters at follow-up (all p < 0.05). These findings support Social Control theory in adult drug use cessation. Future research should extend the length of follow-up and assess bidirectional influences.
The purpose of this study was to examine the physical and emotional well-being and social support in newly diagnosed head and neck cancer (HNC) patients and caregivers and identify sociodemographic, clinical, and behavioral risk factors associated with compromised well-being in patients and caregivers. Newly diagnosed HNC patients and their primary caregivers (N = 72 dyads) completed questionnaires before treatment assessing physical and mental well-being, depression, cancer worry, and open-ended support questions. Patients reported worse physical well-being than caregivers (p < 0.05) but similar levels of mental well-being. Caregivers reported providing emotional and instrumental support most frequently with an emphasis on nutrition and assistance with speech, appearance, and addictions. Both patients and their caregivers reported suboptimal mental well-being and depression. Smoking was associated with compromised well-being in patients, caregivers, and dyads. Compromised well-being in patients and their caregivers was more likely when patients were younger, had worse symptoms, and smoked/consumed alcohol (p < 0.05). While patients face more physical strain than caregivers, both equally confront emotional challenges. Results highlight risk factors for compromised well-being in both patients and their caregivers that should be assessed at diagnosis to guide identification of needed dyadic-focused supportive care resources.
Active injection drug users (IDUs) are at high risk of unsuccessful highly active antiretroviral therapy (HAART). We sought to identify baseline factors differentiating IDUs' treatment success versus treatment failure over time among those taking HAART. Interventions for Seropositive Injectors-Research and Evaluation (INSPIRE) study participants were assessed at baseline and at 6- and 12-month follow-ups. Multinominal regression determined baseline predictors of achieving or maintaining viral suppression relative to maintaining detectable viral loads over 12 months. Of 199 participants who were retained and remained on HAART, 133 (67%) had viral load change patterns included in the analysis. At follow-up, 66% maintained detectable viral loads and 15% achieved and 19% maintained viral suppression. Results indicated that those having informal care (instrumental or emotional support) were 4.6 times more likely to achieve or maintain viral suppression relative to experiencing treatment failure. Those who maintained viral suppression were 3.5 times less likely to live alone or to report social discomfort in taking HAART. Study results underscore the importance of microsocial factors of social network support, social isolation, and social stigma for successful HAART outcomes among IDUs. The findings suggest that adherence interventions for IDUs should promote existing informal HIV caregiving, living with supportive others, and positive medication-taking norms among social networks.
Among HIV-positive injection drug users (IDUs), we examined baseline predictors of lending needles and syringes, and sharing cookers, cotton, and rinse water in the prior 3 months at follow-up. Participants were enrolled in INSPIRE, a secondary prevention intervention for sexually active HIV-positive IDUs in four US cities during 2001–2005. The analyses involved 357 participants who reported injecting drugs in the prior six months at either the 6- or 12-months follow-up visit. About half (49%) reported at least one sharing episode. In adjusted analyses, peer norms supporting safer injection practices, and having primary HIV medical care visits in the prior 6 months were associated with reporting no sharing of injection equipment. Higher levels of psychological distress was associated with a greater likelihood of reporting drug paraphernalia sharing. These findings suggest that intervention approaches for reducing HIV-seropositive IDUs’ transmission of blood-borne infections should include peer-focused interventions to alter norms of drug paraphernalia sharing and promoting primary HIV care and mental health services.
