Advancing the Measurement and Classification of Lower Urinary Tract Dysfunction
Specific Aim 1: To assess the correspondence between 1) average daily recall over 7 days and weekly
recall of self-reported LUTS and 2) average daily recall over 30 days and monthly recall of self-reported
Hypothesis 1.1: There will be an association between average daily recall and weekly recall of selfreported
Hypothesis 1.2: There will be an association between average daily recall and monthly recall of selfreported
Subaim 1A: To understand the heuristics that people may use to construct their weekly and
monthly reports of LUTS (e.g., reporting peaks/valleys or most recent experience).
Subaim 1B: To describe the daily variation in symptoms over time and assess correspondence
between variability based on daily report and weekly or monthly recalled level of that symptom.
Subaim 1C: To model trends in symptoms over the daily measurement periods, e.g., a decrease
in symptoms may indicate increasing awareness of symptoms that lead to actions (drinking less, using
the toilet more) that may reduce the symptom.
Subaim 1D: To assess the effect on weekly survey responses of having a prior week of daily
surveys versus a prior week with no daily surveys.
Specific Aim 2: To assess the associations between better recall of LUTS and patient characteristics,
including bother, depression, anxiety, mood, and episodic memory.
Hypothesis 2.1: Greater bother will be associated with lower correspondence between different recall
periods, i.e., symptoms are related to over-reporting.
Specific Aim 3: To examine the association between overlapping parameters in a clinical (eventtriggered)
3-day bladder diary and self-reported 3-day and weekly recall.
Hypothesis 3.1: There will be an association between overlapping parameters (i.e., frequency, leaking,
urgency) in the bladder diary and 3-day and weekly recall.
