An uncontrolled, feasibility study of a group intervention to reduce hepatitis C transmission risk behaviours and increase transmission knowledge among women who inject drugs

Aims: This study aimed to develop and test the feasibility, acceptability and initial effectiveness of a three-session psychosocial group intervention to reduce hepatitis C risk behaviours and increase hepatitis C transmission knowledge among women who inject drugs in five European cities/towns. Methods: An uncontrolled, field effectiveness study of a psychosocial group intervention. Hepatitis C virus (HCV) transmission knowledge, sexual and drug risk behaviours and depressive symptoms were assessed at baseline and one-month post-intervention. Intention-to-treat analyses were conducted. Findings: One-month post-intervention, a significant increase was reported in HCV transmission knowledge and in the number of new and unused needles/syringes used to inject. There were significant reductions in the sharing of spoons/containers for mixing that had been used by someone else, sharing of filters, cookers, spoons or water with someone who was hepatitis C positive and the use of alcohol swabs following injection. Conclusions: The intervention showed promising results in reducing some hepatitis C injecting risk behaviours and increasing hepatitis C transmission knowledge among women who inject drugs. These preliminary findings suggest that it is feasible to deliver the intervention in drug treatment settings, and that the intervention was acceptable to both participants and staff.

Brief web-based intervention for college students with comorbid risky alcohol use and depressed mood: Does it work and for whom?

College is a time of increased risk for problematic alcohol use and depressed mood. The comorbidity of these conditions is well documented, but is less well understood, with few interventions designed to prevent or reduce the related consequences. The current study evaluated a web-based personalized intervention for students (N=311) who reported an AUDIT score of 8 or more, a BDI-II score of 14 or more, and reported drinking four (women) or five (men) or more drinks on at least one occasion in the past month. Method: Invited participants were randomly selected from all enrolled undergraduates at a large, public, Pacific Northwestern University. Participants completed a screening and baseline assessment, and those who met study eligibility criteria were randomized to one of four conditions (alcohol only, depressed mood only, integrated, and referral-only control). Follow-up occurred one-month post-intervention. Results: While no main effects for the interventions were found, there were moderation effects, such that students in the alcohol only and integrated conditions who had lower levels of depressed mood or alcohol-related problems at baseline showed greater reductions in alcohol-related problems at follow-up compared to students in the control condition. Implications for interventions are discussed.

Telepractice for pediatric Dysphagia: a case study.

A closed-ended intensive pediatric swallowing telepractice program was developed and piloted in one pediatric patient with Opitz BBB/G and Asperger’s Syndromes, oropharyngeal dysphagia and aerophagia. The present study is a case report. Outcome variables included behavioral, swallowing and quality of life variables, and were assessed at baseline and at the end of the four-week program. Selective variables were also assessed at a follow-up family interview four weeks post program completion. Over the four-week intervention period, the patient demonstrated substantial improvements in: oral acceptance of eating-related objects and a variety of foods (behavioral variable), timing of voluntary saliva swallows and aerophagia levels (swallowing variables) and quality of life. Follow-up interview analysis showed that most skills were retained or improved one-month post intervention. This intensive telepractice program proved to be feasible and effective for this pediatric patient with dysphagia.

A Test of Two Positive Psychology Interventions to Increase Employee Well-Being

Despite an abundance of organizational research on how contextual and individual difference factors impact well-being, little research has examined whether individuals themselves can take an active role in enhancing their own well-being. The current study assessed the effectiveness of two simple, self-guided workplace interventions (“gratitude” and “social connectedness”) in impacting well-being. Sixty-seven university employees participated in one of the two self-guided interventions for 2 weeks and completed self-report measures prior to the intervention, immediately following the intervention, and one-month post-intervention. Growth curve modeling was used to examine the effects of each intervention. Partially supporting hypotheses, the gratitude intervention resulted in significant increases in positive affective well-being and self-reported gratitude but not did significantly impact negative affective well-being or self-reported social connectedness. The social connectedness exercise did not significantly impact any of those four outcomes. However, both interventions related to a reduction in workplace absence due to illness. The study suggests that self-guided, positive psychology interventions (particularly gratitude) hold potential for enhancing employee well-being. Because the interventions are short, simple, and self-guided, there is little in the way of costs or drawbacks for organizations. Thus, these types of interventions seem like a potentially useful component of workplace wellness initiatives. This study is one of the few to examine whether self-guided, positive psychology interventions can enhance well-being. Moreover, this is the first study to examine a social connectedness workplace intervention and the first to demonstrate effects on illness-related absence.

Virtual reality-based post-stroke hand rehabilitation.

A VR-based system using a CyberGlove and a Rutgers Master II-ND haptic glove was used to rehabilitate four post-stroke patients in the chronic phase. Each patient had to perform a variety of VR exercises to reduce impairments in their finger range of motion, speed, fractionation and strength. Patients exercised for about two hours per day, five days a week for three weeks. Results showed that three of the patients had gains in thumb range (50-140%) and finger speed (10-15%) over the three weeks trial. All four patients had significant improvement in finger fractionation (40-118%). Gains in finger strength were modest, due in part to an unexpected hardware malfunction. Two of the patients were measured against one-month post intervention and showed good retention. Evaluation using the Jebsen Test of Hand Function showed a reduction of 23-28% in time completion for two of the patients (the ones with the higher degrees of impairment). A prehension task was performed 9-40% faster for three of the patients after the intervention illustrating transfer of their improvement to a functional task.

Body weight supported treadmill and overground training in a patient post cerebrovascular accident

This study was designed to consider the feasibility and effectiveness of combined body weight support (BWS) treadmill and overground training for a 71-year-old woman 19 months post left embolic middle cerebral artery stroke. The study used a modified single subject withdrawal design (ABAA). Initial baseline performance (A1) was established using a set of functional assessment tools for balance, mobility and gait. Intervention (B) was introduced and removed, and a second baseline performance (A2) was recorded. After a one-month delay, final baseline performance was established. During intervention, the participant was involved in combined BWS training three times/week for eight weeks. Single subject analyses and pre/posttest analyses were conducted. Results revealed that 17 of 20 indicators (85%) nine indicators (89%) performance one-month post intervention. Combined BWS training was feasible and effective in improving and maintaining functional performance in this participant.
