Estimating Student Attrition in School-Based Prevention Studies: Guidance from State Longitudinal Data in Maryland.

Attrition is a critical concern for evaluating the rigor of prevention studies, and the current study provides rates of attrition for subgroups of students and schools who are often sampled for prevention science. This is the first study to provide practical guidance for expected rates of attrition using population-level statewide data; findings indicated that researchers using K-12 school-based samples should plan for attrition rates as high as 27% during middle school and 54% during elementary school. However, researchers should consider the grade levels initially sampled, the length of follow-up, and the specific student characteristics and schools available for sampling. Postsecondary attrition ranged from 45% for bachelor's degree seekers to 73% for associate degree seekers. This practical guidance can help researchers to proactively plan for attrition in the study design phase, limiting bias and increasing the validity of prevention studies.

Patterns in adult sibling relationships after the death of one or both parents.

The authors explored how sibling relationships were affected by the death of one or both parents in the context of the dynamics of those sibling relationships prior to the death. Qualitative data obtained from 66 interviews in a mixed-methods study of adults in middle or older age with at least one living sibling were analyzed for the purpose of finding common patterns that emerged after the death. The patterns were: Even closer; Just us now; New roles, responsibilities, and relationships; Unsettled estate; Never close; From bad to worse; Back together, temporarily; and No change. Implications for social work practice include exploring perceptions of family members regarding patterns and using the concept of ambivalence to normalize sibling relationships.

Views of Intermarried Couples: Implications for Social Work Practice.

Intermarriage, defined here as the marriage between people of different races or different ethnicities, is on the rise in the United States, with one in six newlyweds intermarrying. While public opinion approval of interracial marriage is at an all-time high, racial and ethnic hate crimes are also on the rise, which can affect spouses differently based on their identity. Drawing on a 2022 Qualtrics sample of 287 spouses who intermarried and have children, authors of this article sought to learn what is related to their holding a positive view of intermarriage. Talking openly with one's spouse about differences, children initiating discussions about race, and being consciously aware of the interracial or interethnic aspect of the marriage were predictors. Implications for social work practice, which are predicated on the ability to have open communication between family members and the social worker's comfort with their own racial identity, are included for this growing population of intermarried couples.

Development, Characterization, and Application of Two Reporter-Expressing Recombinant Zika Viruses.

Zika virus (ZIKV), a mosquito-borne transplacentally transmissible flavivirus, is an enveloped virus with an ~10.8 kb plus-strand RNA genome that can cause neurological disease. To facilitate the identification of potential antivirals, we developed two reporter-expressing ZIKVs, each capable of expressing an enhanced green fluorescent protein or an improved luminescent NanoLuc luciferase. First, a full-length functional ZIKV cDNA clone was engineered as a bacterial artificial chromosome, with each reporter gene under the cap-independent translational control of a cardiovirus-derived internal ribosome entry site inserted downstream of the single open reading frame of the viral genome. Two reporter-expressing ZIKVs were then generated by transfection of ZIKV-susceptible BHK-21 cells with infectious RNAs derived by in vitro run-off transcription from the respective cDNAs. As compared to the parental virus, the two reporter-expressing ZIKVs grew to lower titers with slower growth kinetics and formed smaller foci; however, they displayed a genome-wide viral protein expression profile identical to that of the parental virus, except for two previously unrecognized larger forms of the C and NS1 proteins. We then used the NanoLuc-expressing ZIKV to assess the in vitro antiviral activity of three inhibitors (T-705, NITD-008, and ribavirin). Altogether, our reporter-expressing ZIKVs represent an excellent molecular tool for the discovery of novel antivirals.

Adult awareness of a youth-focused anti-tobacco campaign: does having children matter?

Data from a survey of tobacco use conducted in 2001 was used to examine if Florida's youth-focused anti-tobacco media campaign, which focused on cigarette smoking, reached adults. The majority of the sample was white (87%), high school or college educated (85%), and over half with children (56%). Differences in awareness and intentions to quit among adult smokers with and without children were examined. About 50% of adults were aware of the campaign and the awareness of the tobacco industry manipulation theme was associated with intentions to quit, independent of having children. These findings provide evidence that youth-targeted anti-tobacco media campaigns can reach adults; however, to change the behavior of adults who smoke, it may not be appropriate to have a "one-size-fits-all" program. The study's limitations are noted.

Mother-in-Law Reports of Closeness to Daughter-in-Law: The Determinant Triangle with the Son and Husband.

For a mother-in-law (MIL) and daughter-in-law (DIL), the benefits of maintaining a close relationship weave through other central family relationships. Those relationship triangles start with one's son, who is the other's husband, and echo through the raising of any grandchildren from the marriage. The current study examined the factors that related to MIL reports of having a close relationship with her DIL. Using survey data gathered from 267 MILs authors report on a regression model that included six factors that predicted closeness. Within the MIL relationship, the MIL reporting that the DIL was helpful and had similar interests to her predicted a close relationship. When the MIL reported being close to her son and the son being happy with the relationship she had with the DIL, this predicted a closer relationship between the MIL and DIL. The MIL feeling left out within the relationship triangle with the son and DIL was associated with less closeness. Closeness was increased when the MIL reported more time spent per month with the DIL. The article concludes with a discussion of research and practice implications.

The reach of a youth-oriented anti-tobacco media campaign on adult smokers.

BACKGROUND: It remains unclear whether youth-targeted anti-tobacco media campaigns reach adults. We examined the reach of the youth-oriented Florida "truth" campaign to (a) determine the extent to which adult smokers were aware of the campaign and (b) test if that awareness was associated with an intention to quit smoking in the next 30 days. METHODS: Data included 781 adult smokers who in 2001 participated in a 20-min telephone survey designed to examine the effects of the "truth" campaign in Florida. Participants were asked numerous questions aimed at measuring their awareness of the campaign and about their tobacco use. RESULTS: Awareness of the campaign was mixed with 21% confirming the "truth" campaign theme, 45% the "truth" logo, 62% "truth" advertising events, and 68% the "truth" advertising theme. Awareness of industry manipulation was the only variable significantly associated with smokers' intentions to quit (OR=1.66; 95% CI=1.34-2.05) in the multivariate model. CONCLUSIONS: The "truth" anti-tobacco campaign targeted 12-17 year olds in an effort to prevent them from starting to smoke. Despite the awareness, the campaign did not have the "unintended consequence" of influencing adults' intentions to smoke. To change the behavior of adults it is not sufficient to have a youth-focused program.

Psychometric properties of the Beck Depression Inventory-II in low-income, African American suicide attempters.

Cross-cultural examinations of the validity and reliability of the Beck Depression Inventory-II (Beck, Steer, Ball, & Ranieri, 1996) is essential for its use in assessment and monitoring of the effectiveness of suicide interventions across racial groups. We tested the fit of a second-order, two-factor model and the internal reliability of the BDI-II in a sample of 133 African Americans with a recent history of suicide attempts. Additionally, we examined the convergent validity with the Hamilton Rating Scale for Depression (Reynolds & Koback, 1995). The results indicate that the BDI-II is a reliable and valid measure of depressive symptoms for African American suicide attempters.

The Development and Evaluation of Procedures to Assess Child Self-report Item Validity.

Cognitive pretesting (CP) is an interview methodology for pretesting the validity of items during the development of self-report instruments. The present research evaluates a systematic approach to the analysis of CP data. Materials and procedures were developed to rate self-report item performance with CP interview text data. Five raters were trained in the application of that system. Estimates of inter-rater reliability found acceptable to substantial levels of inter-rater agreement. Results from the present study suggest that excellent inter-rater reliability can be achieved in the evaluation of CP data. Guidelines for systematically rating the qualitative data collected using CP methods are provided. Future research should focus on empirical demonstrations of how such rating procedures can lead to improvements in self-report instruments.

Cognitive Pretesting and the Developmental Validity of Child Self-Report Instruments: Theory and Applications.

OBJECTIVE: In the context of the importance of valid self-report measures to research and evidence-based practice in social work, an argument-based approach to validity is presented and the concept of developmental validity introduced. Cognitive development theories are applied to the self-report process of children and cognitive pretesting is reviewed as a methodology to advance the validity of self-report instruments for children. An application of cognitive pretesting is presented in the development of the Elementary School Success Profile. METHOD: Two phases of cognitive pretesting were completed to gather data about how children read, interpret and answer self-report items. RESULTS: Cognitive pretesting procedures identified validity problems with numerous items leading to modifications. CONCLUSIONS: Cognitive pretesting framed by an argument-based approach to validity holds significant potential to improve the developmental validity of child self-report instruments.
