“…It is quite popular to analyze the effect of a predictor measured at baseline on an outcome measured at follow-up while controlling for the outcome at baseline. Studies employing this method have, for example, concluded that while controlling for degree of depression symptoms at baseline, a higher degree of depression symptoms at follow-up can be predicted from higher levels of C-reactive protein and interleukin-6 (Gimeno et al, 2009), underweight (Kim, Noh, Park, & Kwon, 2014), higher body mass index (Dearborn, Robbins, & Elias, 2018), lower self-esteem (Johnson, Meyer, Winett, & Small, 2000), less cognitive control over sad stimuli (Vanderlind et al, 2014), more life stressors (Moos, Schutte, Brennan, & Moos, 2005), higher job demands (Paterniti, Niedhammer, Lang, & Consoli, 2002), poorer relationship quality (Eberhart & Hammen, 2006), and separation (O’Connor, Cheng, Dunn, & Golding, 2005).…”
