Contingency management is effective across cocaine-dependent outpatients with different socioeconomic status

Contingency management (CM) has demonstrated its efficacy for treating cocaine dependence, but there is still some controversy with regard to its dissemination. Understanding how individual differences affect CM outcomes is important for detecting barriers to its dissemination. The aim of this study is to examine the impact of socioeconomic variables in cocaine-dependent outpatients on the effectiveness of CM in a community setting. Cocaine-dependent outpatients (N = 118) were randomized to community reinforcement approach (CRA) treatment or a CRA plus vouchers program. The impact of baseline economic variables, alone and in combination with treatment conditions, on abstinence and retention outcomes after 6 months of treatment was assessed. Results showed that income had no effect on retention or abstinence outcomes after 6 months of treatment in either treatment condition. The addition of a CM component was beneficial for individuals with any socioeconomic status. These results support the generalizability of CM strategies with patients of different socioeconomic status in community settings.

Educational research methods for researching innovations in teaching,learning and assessment: The nursing lecturer as researcher

The author, who has had previous experience as a nurse researcher, has been engaged in helping nurse lecturers to undertake evaluation research studies into innovations in their teaching, learning and assessment methods. In order to undertake this work successfully, it was important to move from thinking like a nurse researcher to thinking like an educational researcher and developing the role of the nursing lecturer as researcher of their teaching.This article explores the difference between evaluation and evaluation research and argues for the need to use educational research methods when undertaking evaluation research into innovations in teaching, learning and assessment. A new model for educational evaluation research is presented together with two case examples of the model in use. The model has been tested on over 30 research studies into innovations in teaching, learning and assessment over the past 8 years.

Factors Affecting Utilization of Family Planning Services in a Post-Conflict Setting,South Sudan: A Qualitative Study

This study aims to explore and examine the conjectures surrounding the utilization of family planning services among currently married couples of childbearing age in Renk County.This study has adopted a qualitative method to collect data on factors affecting the utilization of family planning services through focus group discussions and in-depth interviews, in rural and urban areas of Renk County. It targeted married women, men as well as unmarried men and women. The researchers conducted nine focus group discussions and nine interviews at both Jelhak (rural setting) and Renk (urban setting). The results suggested that the people of Renk County prefer to have large families and therefore choose not to use family planning methods. The data collected was analyzed by means of thematic analysis. This included the construction of a thematic framework, coding, editing and categorization of available data as well as the creation of sub-themes.The result also suggested that perception is a main factor that affects utilization of family planning services with a majority of the people in Renk and Jelhak preferring to have many children in order to increase the family size for some reasons. These are linked to religion, social stigma and taboo that are attached to childless people or users of family planning methods for birth control purposes.The responses revealed some variation in perception between rural (Jelhak) and urban (Renk) areas. Respondents from Renk area reported that some people use family planning services for economic reasons that involve alleviation of financial difficulties and provision of better education when the family size is small. On the other hand, rural people from Jelhak perceive family planning to be socially un-acceptable. Furthermore, men and women of Jelhak reported that after each birth of a child, married couples avoid sexual relationship for a period of two years as means of family planning. Women of both Urban and Rural settings reported intentions to use conventional methods of family planning without the knowledge of their spouses.
