We used provider (n = 112) data that staff at the agency disseminating the Family Check-Up (FCU; REACH Institute) collected to profile provider diversity in community settings and to examine whether provider profiles are related to implementation fidelity. Prior to FCU training, REACH Institute staff administered the FCU Provider Readiness Assessment (PRA), a provider self-report measure that assesses provider characteristics previously linked with provider uptake of evidence-based interventions. We conducted a latent class analysis using PRA subscale scores as latent class indicators. Results supported four profiles: experienced high readiness (ExHR), experienced low readiness (ExLR), moderate experience (ME), and novice. The ExHR class was higher than all other classes on: (1) personality variables (i.e., agreeableness, conscientiousness, openness, extraversion); (2) evidence-based practice attitudes; (3) work-related enthusiasm and engagement; and (4) their own well-being. The ExHR class was also higher than ExLR and ME classes on clinical flexibility. The ME class was lowest of all classes on conscientiousness, supervision, clinical flexibility, work-related enthusiasm and engagement, and well-being. During the FCU certification process, FCU Consultants rated providers' fidelity to the model. Twenty-three of the 112 providers that completed the PRA also participated in certification. We conducted follow-up regression analyses using fidelity data for these 23 providers to explore associations between probability of class membership and fidelity. The likelihood of being in the ExHR class was related to higher FCU fidelity, whereas the likelihood of being in the ExLR class was related to lower fidelity. We discuss how provider readiness assessment data can be used to guide the adaptation of provider selection, training, and consultation in community settings.

The measurement and monitoring of implementation fidelity or of adaptations to interventions in the ways described by the innovative papers in this special issue implies the need for an 'implementation infrastructure' to help assure the quality and hence impact of prevention delivery systems. In our work in Australia through schools and government-funded community services in socially disadvantaged communities we have begun to build such an infrastructure, which we call a Prevention Translation and Support System (PTSS). We offer our methodologies not as a template but as an illustration of one approach, designed for use with community coalitions. We aim to work in respectful partnerships with frontline professionals to construct, test, modify, and implement measurement tools and other electronic resources that can facilitate data-driven decision making and evidence-based practice, and generally promote the translation of prevention science into routine practice. The development and use of these technological resources are supported by community workers called Collective Change Facilitators, who act as a 'human bridge' between the worlds of research and practice. They serve as a critical friend to community coalitions, while also translating the needs of service deliverers back to the researchers and practitioners building the PTSS. One example of this engagement was the development and use of a multidimensional measure of coalition function, the Coalition Wellbeing Survey, that helps coalition leaders plan responsive action to overcome identified areas of difficulty and strengthen coalition function. The need for such a tool, accompanied by comprehensive resources, was identified early in our work as essential for the high-quality implementation by community coalitions of evidence-based services. We conclude that implementation of preventive innovations on a large scale, especially those in which technology is embedded to support measurement and monitoring, calls for the creation of new kinds of intermediate organizations that can help sustain a continuous process of research and quality improvement in the field.

High-quality implementation is important for preventive intervention effectiveness. Although this implies fidelity to a practice model, some adaptation may be inevitable or even advantageous in routine practice settings. In order to organize the study of adaptation and its effect on intervention outcomes, scholars have proposed various adaptation taxonomies. This paper examines how four published taxonomies retrospectively classify adaptations: the Ecological Validity Framework (EVF; Bernal et al. in J Abnorm Child Psychol 23(1):67-82, 1995), the Hybrid Prevention Program Model (HPPM; Castro et al. in Prev Sci 5(1):41-45, 2004. https://doi.org/10.1023/B:PREV.0000013980.12412.cd ), the Moore et al. (J Prim Prev 34(3):147-161, 2013. https://doi.org/10.1007/s10935-013-0303-6 ) taxonomy, and the Stirman et al. (Implement Sci 8:65, 2013. https://doi.org/10.1186/1748-5908-8-65 ) taxonomy. We used these taxonomies to classify teacher-reported adaptations made during the implementation of TOOLBOX™, a social emotional learning program implemented in 11 elementary schools during the 2014-2015 academic year. Post-implementation, 271 teachers and staff responded to an online survey that included questions about adaptation, yielding 98 adaptation descriptions provided by 42 respondents. Four raters used each taxonomy to try to classify these descriptions. We assessed the extent to which raters agreed they could classify the descriptions using each taxonomy (coverage), as well as the extent to which raters agreed on the subcategory they assigned (clarity). Results indicated variance among taxonomies, and tensions between the ideals of coverage and clarity emerged. Further studies of adaptation taxonomies as coding instruments may improve their performance, helping scholars more consistently assess adaptations and their effects on preventive intervention outcomes.

In the field of prevention science, some consider fidelity to manualized protocols to be a hallmark of successful implementation. A growing number of scholars agree that high-quality implementation should also include some adaptations to local context, particularly as prevention programs are scaled up, in order to strengthen their relevance and increase participant engagement. From this perspective, fidelity and adaptation can both be seen as necessary, albeit mutually exclusive, dimensions of implementation quality. In this article, we propose that the relationship between these two constructs may be more complex, particularly when adaptations are consistent with the key principles underlying the program model. Our argument draws on examples from the implementation of a manualized youth voice program (YVP) in two different organizations serving six distinct communities. Through a series of retreats, implementers identified examples of modifications made and grouped them into themes. Results suggest that some adaptations were actually indicators of fidelity to the key principles of YVPs: power-sharing, youth ownership, and engagement in social change. We therefore offer suggestions for re-conceptualizing the fidelity-adaptation debate, highlight implications for measurement and assessment, and illustrate that the de facto treatment of adaptation and fidelity as opposing constructs may limit the diffusion or scaling up of these types of youth programs.

Chemical tank cleaners' occupational diseases and injuries are largely unknown due to a lack of monitoring and limited research. Their potential exposure to highly corrosive chemicals-including sodium hypochlorite, sodium hydroxide, and ferric chloride-suggests that tank cleaners represent an at-risk occupational group. This pilot study explored tank cleaners' risk perceptions and barriers to using personal protective equipment and other protective behaviors in their workplace. Data sources included a survey (n = 29) and interviews (n = 9) with sodium hypochlorite tank cleaners in the United States. Although sodium hypochlorite may become reactive under high temperatures, 12 questionnaire respondents indicated not being concerned about high temperatures within the tank, and 15 were not concerned about exposure via ingestion. Analyses of survey and interview results provide evidence of inadequate training among tank cleaners, their lack of understanding of basic chemical properties and routes of exposure, and limited access to and an incomplete understanding of how to properly use personal protective equipment, particularly respiratory protection. These findings can inform researchers, educators, and safety engineers in developing future studies, interventions, and training to improve tank cleaners' health and safety.

Although a few studies have examined sleep knowledge and attitudes as predictors of sleep behavior, the question of which better predicts actual sleep behavior is still open. Furthermore, the construct of sleep attitudes has been inconsistently defined and measured. We examined both sleep knowledge and attitudes to determine their unique associations with sleep hygiene behaviors, and direct and indirect associations with objective and subjective sleep outcomes. College students (N = 218) completed a series of questionnaires before and after wearing a FitBit Flex accelerometer for 7 days. We collected objective sleep duration and quality using this apparatus, while participants reported subjective sleep outcomes, hygiene behaviors, knowledge, and attitudes. Analyses controlled for self-reported depression, diagnosed sleep disorder, and sleep-related medications. For both objective and subjective measures, more positive sleep attitudes but not greater sleep knowledge was directly associated with longer sleep duration, and indirectly (through sleep hygiene) with better sleep quality. The role of sleep attitudes in sleep-related behaviors and outcomes deserves further investigation as a potentially modifiable factor in sleep intervention efforts.

We describe the adaptation of Familias Unidas, an evidence-based substance use and sexual risk behavior intervention, for obesity prevention in Hispanic adolescents. Intervention developers and experts in pediatric obesity, exercise physiology, dietetics, and the local parks system provided input for changes. Hispanic families also provided input through a series of 21 focus groups conducted before, during, and after an initial pilot test of the adapted intervention. After transcribing audiotaped sessions, we used a general inductive approach and Dedoose qualitative software to derive themes. Results indicated the need for improved health-related family functioning, enhanced nutrition education and skill building, increased family engagement in physical activity, and stronger links between family and environmental supports. Parents who participated in the pilot test expressed high enthusiasm for hands-on nutrition training and reported improvements in family functioning. Adolescents liked outdoor physical activities but wanted parents to be more engaged in joint physical activity sessions. The adapted intervention maintains fidelity to Familias Unidas' core theoretical elements and overall structure, but also includes content focused on physical activity and nutrition, adolescent participation in physical activity sessions led by park coaches, and joint parent-adolescent participation in physical activity and nutrition skill-building activities.

Venue-based distribution of marijuana has become the normative model in the United States to obtain marijuana. This study examines one-time purchase behaviors at medical marijuana dispensaries (MMDs) to identify potential venue- and individual-level targets for prevention. We used a two-stage, venue-based sampling approach to randomly select patrons exiting 16 MMDs in Los Angeles, California during the spring of 2013. Patrons (N = 595) reported their discrete purchase behaviors during their most recent visit to the sampled MMD. We used hierarchical linear modeling to examine the amount spent on marijuana products, regressed on characteristics of the sampled dispensaries and their patrons. We used hierarchical generalized linear modeling to examine the likelihood of purchasing specific types of marijuana products and total grams of loose-leaf buds purchased. Patrons spent US$41.73 on average, with a range of $0-$330. We observed significant variation in purchase behaviors across MMDs and associations between venues located within high median income census tracts and a higher total amount spent and lower odds of purchasing only loose-leaf buds. The networked distance between a patron's home and the sampled MMD was positively associated with the total amount spent and total quantity of buds purchased. We also found significant relationships between medical conditions reported for use in three models: total amount spent, purchase of pre-rolled joints, and total grams of buds purchased. Policy makers may want to explore regulating the availability of specialty items that may be attractive to naïve users, such as pre-rolled joints or edibles, or high-concentration products that may be sought out by regular, heavy users.

Although adolescent sexual minority males (ASMM) are at increased risk for human immunodeficiency virus (HIV) in the United States (US), studies that estimate sexual risk behaviors that contribute to HIV risk in ASMM are limited. We completed a systematic review and meta-analysis to compile available data and estimate the prevalence of risk behaviors in this population. We searched four databases for key terms related to ASMM, defined as males aged 14 through 19 who identified as gay or bisexual, reported sex with a male in their lifetime, and/or were considered sexual minority by the study. Articles eligible for inclusion were in English, from US studies, and reported quantitative data on sexual risk behaviors among ASMM. We extracted data from eligible articles and meta-analyzed outcomes reported in three or more articles using random effects. Of 3864 articles identified, 21 were eligible for data extraction. We meta-analyzed nine outcomes. Sixty-two percent of adolescent males self-identifying as gay or bisexual ever had sex with a male, and 67% of participants from ASMM studies recently had sex. Among ASMM who had sex in the last 6 months or were described as sexually active, 44% had condomless anal intercourse in the past 6 months, 50% did not use a condom at last sex, and 32% used alcohol or drugs at their last sexual experience. Available data indicate that sexual risk behaviors are prevalent among ASMM. We need more data to obtain estimates with better precision and generalizability. Understanding HIV risk in ASMM will assist in intervention development and evaluation, and inform behavioral mathematical models.

The Homelessness Prevention and Rapid Re-Housing Program (HPRP) provided individuals and families who were either at-risk or currently experiencing homelessness with time-limited financial and housing support services. Evaluations of HPRP showed a high rate of family placement into permanent housing. However, little research has explored immediate and longitudinal outcomes for families enrolled in HPRP. Using Homeless Management Information System data from Indianapolis, Indiana, we examined demographic and program-related predictors of families entering permanent housing and their risk of reentry into homeless services following HPRP participation. The sample included 511 families who enrolled in the program from 2009 to 2012, with an average follow-up period of 4.5 years. We conducted analyses separately for Homelessness Prevention (HP) recipients (n = 357) and Rapid Re-Housing (RRH) recipients (n = 154). Results revealed that HP families were more likely to enter permanent housing if they: included adults who were older in age, were enrolled longer in the program, were provided rental arrear services and utility payments, and did not receive legal services. RRH families receiving rental assistance services had significantly greater odds of entering permanent housing. Among permanently housed families, at least one family member in 10.9% of HP recipients and 18.8% of RRH recipients reentered homeless services. HP families with younger children and one veteran family member were at increased risk of reentry to homelessness services. RRH recipients who did not receive moving cost services and had more children were at greater risk of reentry. Study findings suggest a need for future research on HP and RRH interventions that identify unique service needs among families who are experiencing housing instability or homelessness.
