Development and validation of the Digital Health Acceptability Questionnaire

Acceptability (of healthcare services) is an important construct that lacks a consistent definition within research. Addressing this issue, a systematic review led to the Theoretical Framework of Acceptability. In this study, we describe the development (based on the Theoretical Framework of Acceptability) and validation of the Digital Health Acceptability Questionnaire. Nineteen items aligning with the Theoretical Framework of Acceptability were developed. Two versions of the questionnaire measuring telehealth acceptability by telephone (N = 644) and videoconference appointment (N = 425), were administered to a nationally representative survey of consumers in Australia. Two exploratory factor analyses (Oblimin rotation) were conducted for each scale (telephone/videoconference). Two-factor solutions (5 items each) were found for both (telephone/videoconference) acceptability questionnaires: (a) attitude toward the service as a means to address healthcare needs and affective attitude and (b) individual capacity and effort to use telehealth. Before rotation, Factor 1 of the telephone scale (α = 0.92) measured 56.18% of the variance and Factor 2 (α = 0.86) measured 14.17%. Factor 1 of the videoconference scale (α = 0.90) measured 56.68% of the variance and Factor 2 (α = 0.85) measured 10.63%. The full10-item acceptability questionnaire showed excellent internal consistency (telephone: α = 0.91 and videoconference: α = 0.92). The 2-dimensional Digital Health Acceptability Questionnaire is a brief survey based on research evidence and validated in a large Australian sample

Effect of over-expression of Linum usitatissimum PINORESINOL LARICIRESINOL REDUCTASE (LuPLR) gene in transgenic Phyllanthus amarus

Shoot tip explants of Phyllanthus amarus were cocultivated with Agrobacterium tumefaciens strain LBA 4404 carrying plasmid pCAMBIA 2301 harbouring genes coding for betaglucuronidase (gus), kanamycin (kan), and neomycin phosphotransferase II (nptII) along with a gene coding for Linum usitatissimum PINORESINOL LARICIRESINOL REDUCTASE (Lu-PLR). Transformed shoot tip explants were maintained in a Murashige and Skoog (MS) medium containing TDZ 1.54 mg l-1, kan 50 mg l-1 and cephotaxime 62.5 mg l-1. The optimum medium for regeneration of multiple shoots was MS supplemented with TDZ 1.54 mg l-1, kan 50 mg l-1. Efficient and effective rooting of plantlets was achieved by culturing the in vitro regenerated shoots on liquid � MS medium containing 0.7 mg l-1 indole 3-butyric acid (IBA) and 5 mg l-1 kan. Rooted plants were acclimatized in the mixtures of vermiculite and soil. The transformation of kan-resistant plantlets regenerated from shoot-tip explants was confirmed by GUS and polymerase chain reaction (PCR) analysis. Southern blot and reverse transcribed PCR (RT-PCR) analysis confirmed successful integration and expression of Lu-PLR gene. Quantitative analysis of phyllanthin performed on transgenic and wild plants using high-performance liquid chromatography (HPLC) revealed that transgenic lines contained higher phyllanthin content (0.3– 0.81% w/w) than wild plants (0.09% w/w). The highest yield of phyllanthin was detected in transgenic lines was upto 1.16, 1.22 and 1.23 folds higher than that of wild plant

Patients’ acceptability of self-selected digital health services to support diet and exercise among people with complex chronic conditions: Mixed methods study

Objective The acceptability of being offered a choice from a suite of digital health service options to support optimal diet and exercise behaviors in adults with complex chronic conditions was evaluated. This study sought to understand many areas of acceptability including satisfaction, ease of use, usefulness and user appropriateness and perceived effectiveness. Methods This mixed-methods study was embedded within a randomized-controlled feasibility trial providing digital health services managing diet and exercise for adults from specialist kidney and liver disease clinics. Post study surveys and semistructured interviews were used to determine patients’ acceptability of the trial interventions. Quantitative (surveys) and qualitative (surveys and interviews) results were merged using integrative analysis and mapped to each construct of the modified version of the Theoretical Framework of Acceptability. Results Seventeen interviews (intervention group) and 50 surveys ( n  = 24 intervention, n  = 26 comparator) completed from a possible 67 participants were analyzed. In the intervention group, the survey results revealed high areas of acceptability for the digital health services including overall support received, ease of use, timely advice and feeling safe. The interviews also revealed high areas of acceptability including convenience, ability to adopt healthier behaviors and having regular interactions with health professionals. However, the interviews also revealed lower areas of acceptability as a result of absence of individualization, low digital literacy, and limitations from life circumstances. Conclusions Recipients of digital health services that supported diet and exercise interventions found these useful, effective, and safe. Individualized care, technical support and patient confidence remain important to improve the acceptability of digital health service interventions
