This intervention includes learning about how to manage one's heart failure. This includes understanding when to seek treatment, monitoring oneself for daily signs and symptoms, daily weight, dietary changes, physical activity, and adherence to medication taking.

Sleepiness will be measured using the Epworth Sleepiness Scale (ESS) a report instrument used to measure general levels of daytime sleepiness or sleep propensity in adults. The instrument asks subjects to rate on a scale of 0 to 3 the chances that he or she would doze in each of eight different situations. ESS scores can range from 0 to 24, with higher scores indicating higher levels of daytime sleepiness.

Anxiety will be measured with the Spielberger State Anxiety Inventory (STAI), a self-report instrument to measure the presence and severity of current symptoms of anxiety. The instrument includes 20 items to evaluate the current state of anxiety, using items that measure subjective feelings of apprehension, tension, nervousness, worry, and activation/arousal of the autonomic nervous system. Scores range from 20-80, with higher scores indicating greater anxiety.

The symptom of fatigue will be measured with the Multidimensional Assessment of Fatigue Scale, a 16 item self-report instrument that measures fatigue according to four dimensions: degree and severity, distress that it causes, timing of fatigue, and its impact on various activities of daily living. The items are used to calculate scores for each of the four dimensions listed, as well as a global fatigue index (GFI). A higher score indicates more severe fatigue, fatigue distress, or impact on activities of daily living.

Sleep efficiency refers the ratio of time spent asleep to the amount of time spent in bed. Sleep efficiency will be subjectively measured with the Pittsburgh Sleep Quality Index, an instrument used to calculate self-reported sleep duration, sleep efficiency sleep latency, sleep disturbances, and global sleep quality. The 19 self-rated items are calculated to provide a global score ranging from 0-21, with "0" indicating no difficulty, and "21" indicating severe difficulty in all areas. Sleep efficiency will also be objectively measured using actigraphy, a method of inferring sleep from the presence or absence of wrist movement. Participants will wear the Respironics Minimitter Actiwatch AW2, a wrist-worn actigraph, to elicit objective sleep efficiency for a two week period. Participants will also complete a daily diary (lights out/on, times/purpose of removal, hypnotic use) for use in interpretation of actigraphy data.

Functional performance will be measured with the Medical Outcomes Study (MOS) SF36v2 Physical Functioning Scale. The SF36v2 is a multi-purpose self-reported health survey that yields an 8-scale profile of functional health and well-being. The physical functioning scale assesses performance of daily activities, with the lowest score indicating an individual who is very limited in performing all physical activities, including bathing or dressing, and the highest score indicating an individual who can perform all types of vigorous physical activity without limitations due to health.

This will be measured with a 16 item likert scale. The Dysfunctional Beliefs and Attitudes about Sleep Scale

We will measure urinary free cortisol as a biological measure of stress. Participants will provide urine specimens in the morning (from the previous night) and again late in the afternoon (reflecting the afternoon). This will enable understanding of both day and night levels of stress.

We will measure melatonin as a biological measure of the circadian rhythm. Participants will provide urine specimens in the morning (from the previous night) and again late in the afternoon (reflecting the afternoon). This will enable understanding of both day and night levels of stress.

We will measure epinephrine ("adrenaline") as a biological measure of stress. Participants will provide urine specimens in the morning (from the previous night) and again late in the afternoon (reflecting the afternoon). This will enable understanding of both day and night levels of stress.

We will measure norepinephrine as a biological measure of stress. Participants will provide urine specimens in the morning (from the previous night) and again late in the afternoon (reflecting the afternoon). This will enable understanding of both day and night levels of stress.

We will measure shortness of breath, nocturnia, and pain. Participants will complete a daily diary each morning upon awakening and indicate on a 10 item numeric scale the degree to which they experienced these symptoms during the past night.
