Consumer behaviour and decisions to buy from online retailers were increasingly influenced and changed by social media. Because of the never-ending advances in information technology, online shopping is becoming more popular. Therefore, this study aimed to examine the mediating effect of social media on online shopping behaviour in Nigeria. A cross-sectional study was used, and a simple random sampling procedure was used to select three hundred and eighty (380) online shoppers. Data were analysed using Structural Equation Modelling –Partial Least Square (SEM-PLS). The analysis revealed that advertising had an insignificant effect on online shopping behaviour with a path coefficient (Beta value = 0.11; t value = 1.743; p= 0.082). There is positive relationship between advertising and social media effect (Beta value = 0.787; t value = 34.556; p= 0.000). the proposed relationship between social media effect and Online Shopping Behaviour (=0.378; t-value =5.735; p =0.000) is supported. In contrast, the projected relationship between Trust and Online Shopping Behaviour is (=0.466; t-value =12.817; p =0.000). Lastly, the result revealed there is a strong correlation between Trust and Online Shopping Behaviour.
The strategic visions in the health care system now underpin application of Information Communication Technology for effective care delivery. Recognising the potentials of ICT for Health, the Nigerian government as part of its policy derive towards achieving effective health care delivery by the year 2020, adopted use of ICT for effective healthcare delivery. Part of the target was establishment of ICT/Health informatics units in teaching hospitals in the country. This study assessed level of knowledge and utilization of health informatics among medical doctors in Ahmadu Bello University, Shika-Zaria. Premised on the Unified Theory of Acceptance and Use of Technology, this study adopted descriptive survey method and structured questionnaire as its instrument of data collection. Findings revealed that 91.4% (n=201) of the 220 sampled medical doctors in ABUTH are aware of health informatics and that 68.2% (n=150) have knowledge of how to use it. The most prominent areas of health informatics among the medical doctors are ‘Management Information System’, ‘Electronic Health Record System’ and ‘Electronic Medical Record’. However, only 58.6% (n=129) of the medical doctors in BUTH Shika- Zaria are actually utilizing health informatics. Internet (n=133, 60.5%) and interpersonal sources (n= 71, 32.3%) were found to be the major sources of information of knowledge and utilization of health informatics among the medical doctors. The study therefore recommends that ABUTH, Shika-Zaria should put in place more mechanism for creating awareness on use of health informatics varieties and a strong need for time-series research to examine future development in respect to knowledge and utilization of health informatics in Nigerian health institutions.
Exploratory factor analysis (EFA) is a technique for determining a measure’s factor structure and assessing its internal consistency or reliability. EFA is essential for determining which components should be included in the study instrument. Social media is one of the most critical factors that affect online shopping behaviour. Thus, this study aims to use exploratory factor analysis to validate an instrument measuring social media in the context of online shopping. The questionnaire used in this study is adapted from previous studies. The researchers utilised a cross-sectional research design to conduct the EFA, collecting data from 100 respondents using a structured survey. The result shows that the construct has one component. The KMO is 0.892, and the outcome of Bartlett’s Test of Sphericity was significant (Chisquare = 510.816, p-value 0.000; this indicated that the data are okay to proceed. Cronbach’s Alpha was higher than 0.7, meaning that all items are reliable. The study concludes that the instruments used to measure social media in this research are valid and reliable.
