RESUMO
BACKGROUND: Although many behavioral interventions are adapted, little is known about the reasons for adaptations and the process and outcomes influencing adaptations. To address this gap, we explored the adaptations made to promote HIV prevention services, including HIV self-testing (HIVST), among Nigerian youth. METHODS: The main objective of this qualitative case study design was to document the adaptations made over time using the Framework for Reporting Adaptations and Modifications - Expanded (FRAME). Between 2018 and 2020, we organized four participatory activities as part of the 4 Youth by Youth project to increase the uptake of HIVST services in Nigeria-an open call, a designathon, a capacity-building bootcamp and a pilot feasibility trial. We also began the process of implementing a final intervention using a pragmatic randomized control trial (RCT). The open call solicited creative strategies to promote HIVST among Nigerian youth and then had experts evaluate them. The designathon brought together youth teams to further develop their HIVST service strategies into implementation protocols. Teams determined to be exceptional were invited to a four-week capacity-building bootcamp. The five teams that emerged from the bootcamp were supported to pilot their HIVST service strategies over a 6-month period. The adapted intervention is currently being evaluated in a pragmatic RCT. We transcribed meeting reports and conducted document reviews of study protocols and training manuals. RESULTS: Sixteen adaptations were identified and categorized into three domains: (1) modifications to the content of the intervention (i.e. photo verification system and/or Unstructured Supplementary Service Data (USSD) system to verify HIVST); (2) modifications to the delivery the intervention (i.e. implement participatory learning community sessions to provide supportive supervision and technical support); (3) modifications to the evaluation processes (i.e. economic evaluation to estimate the cost of implementing intervention on a larger scale). Frequent reasons for adaptation included increasing intervention reach, modifying interventions to enhance their appropriateness and fit with the recipient, and increasing the intervention's feasibility and acceptability. Most adaptations were planned and reactive, and the need for modifications was determined by the youths, 4YBY program staff, and advisory group. CONCLUSIONS: Findings suggest that the nature of adaptations made throughout the implementation process reflects the necessity of evaluating services in context while adjusting to specific challenges as they are identified. Further research is needed to understand the effect of these adaptations on the overall intervention effect as well as the quality of youth engagement.
RESUMO
Two Schiff bases, (E)-1-(4-methoxyphenyl)-N-((E)-3-(4-nitrophenyl)allylidene)methanamine (compound 1) and (E)-N-((E)-3-(4-nitrophenyl)allylidene)-2-phenylethanamine (compound 2) have been synthesized and characterized using spectroscopic methods; time of flight MS, 1H and 13C NMR, FT-IR, UV-VIS, photoluminescence and crystallographic methods. The structural and electronic properties of compounds 1 and 2 in the ground state were also examined using the DFT/B3LYP functional and 6-31 + G(d,p) basis set, while the electronic transitions for excited state calculations were carried out using the TD-DFT/6-31 + G(d,p) method. The Schiff base compounds, 1 and 2 crystallized in a monoclinic crystal system and the P21/c space group. The emission spectra of the compounds are attributed to conjugated π-bond interaction while the influence of the intra-ligand charge transfer resulted in a broad shoulder for 1 and a double emission peak for 2. The calculated transitions at 450 and 369 nm for 1 and 2 respectively are in reasonable agreement with the experimental results. The higher values of dipole moment, linear polarizability and first hyperpolarizability of 1, suggest a better optical property and better candidate for the development of nonlinear optical (NLO) materials.
