Wow! JW is barking up the wrong tree again. Dr. D is correct that the scales where LPE (Low Positive Emotion) fall within are not as empirically reliable. I found this on a site that is helpful:
"These scales are more obvious (and more fakable than the MMPI-2 Clinical Scales). They are meant to be more distinct, and supposedly clearer forms of the Clinical scales (Tellegen, Ben-Porath, McNulty, Arbisi, Graham, and Kaemmer, 2003). They may be helpful as sub-scales to the MMPI-2 Clinical scales, but not as separate clinical scales. They are redundant to the content scales, but are not better than the MMPI-2 Clinical Scales "
