The phenomena of depression and anxiety co-occurrence have drawn much clinical and empirical attention since recently acknowledged as a distinct and separated diagnosis. Although important implication in terms of treatment and prognosis, the phenomenology of mixed anxiety and depression disorder (MAD) is not well understood. Review of studies aiming to measure this phenomenon reveals multiplicity of perspectives when relating to the basic presentation of mixed depression and anxiety. In my study we review the possible patterns of presentation on the basis of past research as well as in theoretical models. In light of this review, we propose several competing hypotheses regarding the relationship between anxiety and depression. Possible patterns of presentation can vary from corresponding fluctuations between these two affects, to stable levels of one affect accompanied with variations in the other. Using a longitudinal time series design and analysis, we aim to measure and record these changes on a daily basis.
