Size of University Classes and Student Evaluations of Teaching.

For 981 undergraduate classes, mean student ratings of instruction decrease with increasing class size. This relationship remains strong when other variables known or believed to influence ratings are held constant.

Mano a Mano-Mujer: An Effective HIV Prevention Intervention for Chilean Women

The impact of a professionally facilitated peer group intervention for HIV prevention among 400 low-income Chilean women was examined using a quasiexperimental design. At 3 months postintervention, the intervention group had higher HIV-related knowledge, more positive attitudes toward people living with HIV, fewer perceived condom use barriers, greater self- efficacy, higher HIV reduction behavioral intentions, more communication with partners about safer sex, and decreased depression symptoms. They did not, however, have increased condom use or self-esteem. More attention to gender barriers is needed. This intervention offers a model for reducing HIV for women in Chile and other Latin American countries.

A primary health care intervention to mobilize health workers for HIV prevention in Malawi

For the last 4 years we have implemented a model to mobilize rural health workers as leaders for HIV prevention in Malawi. We use a conceptual framework that integrates the World Health Organization’s (WHO) primary health care (PHC) model, the social‐ cognitive model of behavioural change, and contextual tailoring of the intervention. Health workers are potential rural HIV prevention leaders because they have community trust and respect. However, their leadership potential has been limited by both health system barriers such as inadequate workers, supplies, and training and personal barriers such as risky occupational and personal behaviours. In the first phase of the project, we developed collaborative relationships and conducted qualitative research to adapt a peer group intervention for rural health workers and community members. In the ongoing second phase, we trained the health workers, who then volunteered and provided the intervention to adults in the communities their health centres serve. The intervention was adapted for young people through a community participatory process. Currently the adapted intervention is being offered to young people. As a guide to replication, we discuss barriers encountered in implementing this collaborative project and how we overcame them. This project demonstrates that health workers can be effective leaders for community AIDS prevention in African countries. The primary health care model offers a feasible, cost-effective and sustainable approach to maximizing health worker-community collaboration to reduce the spread of HIV.

Outcomes of an HIV Prevention Peer Group Intervention for Rural Adults in Malawi

This study used a quasi-experimental design to evaluate a six-session peer group intervention for HIV prevention among rural adults in Malawi. Two rural districts were randomly assigned to intervention and control conditions. Independent random samples of community adults compared the districts at baseline and at 6 and 18 months postintervention. Using multiple regressions controlling for six demographic factors, intervention district adults had significantly more favorable outcomes at 6- and 18-month evaluations for condom attitudes, self-efficacy for community prevention, self-efficacy for practicing safer sex, partner communication, using condoms ever in the past 2 months, and community prevention activities. Knowledge and hope for controlling the epidemic were significantly higher in the intervention district only at the 6-month evaluation; having a recent HIV test was significantly higher only at 18 months. Levels of stigma and the number of risky sex practices did not decrease when demographic factors were controlled. Expanding peer group intervention for HIV prevention would benefit rural adults.

Evaluating College Teaching as Leadership.

Leadership studies provide a perspective from which to view college teaching. Evidence is presented for conceptual and perceptual similarities between leadership and teaching. Both the number and content of dimensions found in descriptions and evaluations of both teaching and leadership are similar. Hypotheses validated in leadership studies also receive empirical support from teacher evaluation data. The examination of teaching in the context of measuring leadership suggests guidelines for designing programs to evaluate and to improve teacher effectiveness.

Process evaluation of HIV prevention peer groups in Malawi: a look inside the black box

This paper reports the process evaluation of a peer group intervention for human immunodeficiency virus (HIV) prevention which had positive outcomes for three target groups in Malawi: rural adults, adolescents and urban hospital workers. The six-session intervention was delivered to small groups of 10-12 participants by 85 trained volunteer peer leaders working in pairs. A descriptive, observational mixed methods design was used with a convenience sample of 294 intervention sessions. Using project records and a conceptually based observation guide, we examined five aspects of the implementation process. The context was favorable, but privacy to discuss sensitive issues was a concern for some groups. In study communities, program reach was 58% of rural adults, 70% of adolescents and nearly all hospital workers. Session records confirmed that all peer groups received the intended six sessions (dose delivered). The dose received was high, as evidenced by high participant engagement in peer group activities. Peer leaders were rated above the median for three indicators of peer group content and process fidelity: session management skills, interpersonal facilitation skills and whether more like a peer group than classroom. Documenting that this HIV prevention peer group intervention was delivered as intended by trained peer volunteers supports widespread dissemination of the intervention.

IMPACT OF A PEER-GROUP INTERVENTION ON OCCUPATION-RELATED BEHAVIORS FOR URBAN HOSPITAL WORKERS IN MALAWI

&NA; Using a pre‐ and posttest design with no control group, the authors evaluated the impact of a peer‐group intervention on work related knowledge and behavior for health workers at an urban hospital in Malawi. The authors surveyed unmatched random samples of health workers, observed workers on the job, and interviewed clients about hospital services at baseline and at 6 months after the intervention. Universal precautions knowledge, reported hand washing, and reported client teaching were significantly higher at the final evaluation. The outcome differences remained robust in multivariate analyses with controls for demographic factors of age, gender, education, food security, and job category. Observations reported consistently greater use of universal precautions, more respectful interactions, and more client teaching at final evaluation. Patient surveys reported more discussion with health workers about HIV at the final evaluation. Peer‐group interventions can prepare health workers in Malawi for HIV prevention and offer a potential model for other African countries.

Short-term effects of a peer group intervention for HIV prevention among trainee teachers in Malawi.

This report describes the implementation and short-term results of a peer group intervention for HIV prevention on the HIV-related attitudes, knowledge and behaviours of primary school teachers in Malawi. The intervention, based on the social-cognitive learning model, took place in 2000 at two teacher training colleges with a distance-learning programme. Primary school teachers attending a final six-week training session before certification volunteered to participate. Group leaders were teachers selected by each group, and after training they facilitated the peer group intervention. The teachers completed a pre-test and post-test questionnaire. The 286 trainee teachers whose pre- and post-test samples could be matched, largely reported positive changes in their HIV-prevention-related knowledge, attitudes, self-efficacy, behaviour change and condom-use intentions. However, at post-test immediately after the intervention they did not show a higher level of perceived-risk, a greater hope that people could change their high-risk sexual behaviour, or greater agreement that persons infected with HIV should be allowed in public places. This research demonstrates the feasibility of an HIV-prevention intervention for primary school teachers during their training. The Malawi Ministry of Education has since made the programme available to over 90 per cent of all trainee teachers through an NGO.

HIV Risk Reduction Intervention for Rural Adolescents in Malawi

Malawian adolescents are at risk for HIV infection. Using a quasi-experimental two-group research design, we determined the efficacy of Mzake ndi Mzake Kuunikira Achinyamata (MMKA) in enhancing 13- to 19-year-old Malawian males’ and females’ HIV knowledge, attitude about HIV, self-efficacy for condom use and for safer sex, and HIV risk reduction behaviors. The regression analyses revealed that compared with their cohorts in the control community, the adolescents in the MMKA community had significantly better scores on the outcome variables. The intervention had significant benefits for male and 16- to 19-year-old adolescents but not for 13- to 15-year-old female adolescents. Tailored interventions are needed for these females.

Improving universal precautions and client teaching for rural health workers: a peer-group intervention

Abstract Health workers can contribute to HIV prevention by minimizing HIV transmission in health facilities and increasing client teaching. We offered a peer-group intervention for Malawian rural health workers to build their universal precautions and teaching skills. A quasi-experimental design using independent sample surveys and observations compared health workers in an intervention and delayed intervention control district at baseline and at 15 and 30 months post-intervention. Controlling for demographic factors, the intervention district had more reported HIV teaching at 15 and 30 months and also had higher universal precautions knowledge and fewer needle stick injuries at 30 months. Observations at 15 and 30 months post-intervention showed higher levels of teaching in the intervention district. Observed glove wearing and hand washing were also higher at 30 months. This intervention should be made available for health workers in Malawi and provides a potential model for other high-HIV prevalence countries.
