"Thanks Blair. I do have access to SPSS through my University, so can you tell me where I can download macros for this calculation. I think I could do without the steep learning curve of R. You have been truly helpful in guiding me through this maze…"
"You'll want to use the Fisher r-to-z conversion for analyses (and convert z-to-r for interpretation). Sources like Lipsey & Wilson (2001, Practical Meta-Analysis) will lead you through the problems. They also offer macros for meta-analysis…"
"Thanks for your quick reply Blair.
The aim is to study the relationship between 1) attendance and predictors (say for e.g. pain, self efficacy etc.) and 2) adherence and predictors (which can be same or different as attendance) and 3) if possible,…"
"Seems like attendance and adherence are both continuous variables. Most people would put them into the r metric, as you intuited. What happens in the studies? Do researchers commonly report the associations in terms of r or standardized beta…"
Hi, I intend to conduct a meta analysis of quantitative studies which explore the predictors (barriers and facilitators) related to attendance and adherence. I am a bit confused as to whether 'r' is the correct effect size index to be used. My background is healthcare, so am not very good with statistics. My question specifically is that we have 2 independent variables - 1. Attendance2. AdherenceWe need to measure the relationship between predictor (e.g. pain) with adherence as well as…See More
