Article Analysis: Data Collection and Measurement
Question one
The researchers have a sufficient and holistic operational and conceptual definition based on the theory of self-efficacy and the concept of social learning.
Question two
The major variable in this study was increase in knowledge on Osteoporosis. This variable was operationalized using interviews which were conducted in Mandarin to enhance the quality of data and reduce communication challenges. All methods and tools used had been proved effective on Caucasians in the reviewed literature.
Question three
The key instruments such as the Osteoporosis Knowledge Test and self-efficacy questionnaires have been described adequately in the study and supported by relevant literature. The tools are suitable for the target population and customizing the questionnaires to Mandarin reduced communication barriers enabling data collection from participants who were not conversant in English.
Question four
The methods used yielded reliable and valid data as demonstrated by the test of significance conducted a p<.05.
Question five
The intervention in this study was an education program designed to enhance self-efficacy on Osteoporosis, individualized supplementary handbooks, screening and individualized goals and exercise tips for use at home. The control group received general information on well being and cerebro-vascular diseases with no mention of exercise as a prevention strategy. All the allocated participants received the intervention. The intervention was effectively implemented because experienced nurse researchers were used in the presentation of the intervention.
Question six
Data collection minimized bias though the use of identical data collection tools for both the intervention and control group. Data collection was conducted by the researchers who have adequate training and experience in research.
