Kendall, I had used Software named FACTOR to carry out EFA. Since all the variables were measured on binary scale, I came to know that this is the software that accommodates EFA  for such type of variables. The rotation method was Promin. I used parallel analysis  to determine the number of suggested dimensions. The results suggested two dimensions on the basis of Parallel analysis. Next I ran MRFA to extract the dimensions. All these options were set by default and recommended by the developers of the software. An anomaly I only later noted is that 9 out of 16 variables had commonalities equal to 1 (heywood case). Does this invalidate my entire EFA? I didn't observe any complex loadings. 3 variables didn't load on to any factor and were removed from the scale.
