First, I hope this is the appropriate venue for this. I have asked other people and they steered me here.

I’m trying to use BHPS data to construct marital quality trajectories among cohabitors using mixture (LCGA) models. I’ve downloaded all the data and found one measure of marital quality (XLfsat4; how satisfied are you with your husband/wife/partner) in waves F-R, with the curious exception of wave K. I have two questions.
1. Is XLfsat4 available in wave k? I have been unable to locate it. It seems a curious omission, so I’m sure I’m missing something.
2. Are there any additional measures of romantic relationship quality in the BHPS? I have searched for a long time for additional indicators but thus far have found nothing.

I appreciate your help in this matter. Thank you for your time.
