Quality of Life-Menopause Specific

"The Quality of life-Menopause specific is assessed by the Menopause Specific Quality of Life (MENQOL).~The MENQOL is self-administered and consists of a total of 29 items in a Likert-scale format. Each item assesses the impact of one of four domains of menopausal symptoms, as experienced over the last month: vasomotor (items 1-3), psychosocial (items 4-10), physical (items 11-26), and sexual (items 27-29). Items pertaining to a specific symptom are rated as present or not present, and if present, how bothersome on a zero (not bothersome) to six (extremely bothersome) scale. Means are computed for each subscale by dividing the sum of the domain's items by the number of items within that domain. Non-endorsement of an item is scored a 1 and endorsement a 2, plus the number of the particular rating, so that the possible score on any item ranges from 1-8. Total score also ranges from 1-8." (NCT02040532)
Timeframe: Baseline, study completion at 7 weeks

Quality of Life-Overall

Quality of life-Overall was assessed with the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q). The Q-LES-Q is a 16-item self-report questionnaire that assesses enjoyment of and satisfaction with life. The scoring of the Q-LES-Q-SF involves summing only the first 14 items to yield a raw total score. The last two items are not included in the total score but are standalone items. The raw total score ranges from 14 to 70 with higher scores indicating higher quality of life enjoyment and satisfaction. (NCT02040532)

Severity of Insomnia

"Severity of insomnia was measured throughout the study using the Insomnia Severity Index (ISI) .The ISI is a 7-item scale that evaluates the severity of insomnia retrospectively over the past week. The scale is more specific to insomnia symptoms than the Pittsburgh scale (PSQI), which focuses more broadly on overall sleep quality.~The ISI score ranges from a minimum of 0 to 28. A score of 0-7=no clinically significant insomnia, 8-14=subthreshold insomnia, 5-21=clinical insomnia (moderate severity), 22-28=clinical insomnia (severe), with higher values indicating more severe insomnia." (NCT02040532)
Timeframe: Baseline, study completion at 7 weeks

Sleep Quality and Disturbances Over Past Month

"Sleep quality and disturbances during the past month were assessed with the Pittsburgh Sleep Quality Index (PSQI). The PSQI also incorporates daytime functioning into the total score.~In scoring the PSQI, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality." (NCT02040532)

Vasomotor Symptoms (VMS) Frequency, Severity, and Bothersomeness During Daytime

Vasomotor symptoms (VMS) were tracked and quantified prospectively using a daily hot flash diary. The hot flash diary was adapted from a 7-day self-report tool for vasomotor symptoms originally developed by the North Central Cancer Treatment Group (NCCTG). The diary asks for the subject to log number of hot flashes during the day and night, severity of hot flashes during day and night, and how bothersome the hot flashes were during day and night. Vasomotor symptoms were also systematically assessed at baseline, week 4, and week 7 using the Hot Flash-Related Daily Interference Scale (HFRDIS), a 10-item self-report questionnaire to determine perceived hot flash interference with quality of life and daily activities.

Hot Flash Severity Score

The patients kept daily hot flash diaries, including the total number of hot flashes they characterized as mild, moderate,severe and very severe. Hot flash severity scores were calculated by assigning one point to each mild hot flash, two points for each moderate hot flash, three points for each severe hot flash and four points for each very severe hot flash. The hot flash severity score for a 24 hour period was the sum of these scores. The score was calculated for each day in the diary. For each subject, median scores were calculated for each week (7 day period) of participation. The median hot flash severity score for the first week was considered the baseline. The median hot flash severity score for the fourth week is considered the week 4 time point. The median hot flash severity score for the eighth week is considered the week 8 time point. The median result for the group was then calculated at each of the timepoints. (NCT00711529)

"Depression & anxiety were measured by using the Hospital Anxiety & Depression Scale (HADS).~The HADS was developed to assess anxiety & depression. It is meant to differentiate symptoms of depression with those of anxiety.~Number of items: 14 (7 questions relating to anxiety; 7 questions relating to depression).~Responses are based on the relative frequency of symptoms over the past week, using a four point scale ranging from 0 (not at all) to 3 (very often indeed).~Responses are summed to provide separate scores for anxiety and depression symptomology with possible scores ranging from 0 to 21 for each scale.~The results presented below are the percentage of participants with abnormal HADS Scores for both Abnormal Anxiety & Abnormal Depression at Week 4 and Week 12."

Effect of Paroxetine Mesylate Capsules on Percent Improvement of Hot Flash Interference From Baseline at Week 4 and Week 12, Hot Flash Related Daily Interference Scale (HFRDIS)

"Interference of hot flashes was measured by using the hot flash-related daily interference scale (HFRDIS). The HFRDIS is a 10-item scale that measures the degree to which hot flashes interfere with 9 daily activities and the tenth item measures the degree to which hot flashes interfere with each of the other items. Subjects can score for each item on a scale from 0 to 10 where 0 = Do not interfere and a score of 10 = Completely interferes.~The measure being reported below is percentage of responders who had an improvement in HFRDIS score at Week 4 and Week 12 compared to baseline. A responder is defined as a subject who had an improvement in the HFRDIS score. An improvement is defined as a score ≤3 on each question." (NCT01101841)
Timeframe: Week 4 and Week 12

Mean Change From Baseline in Hot Flash Frequency at Week 4 and Week 12.

"Subjects recorded the number of hot flashes per week using an electronic diary. The results reported are not hot flashes per week.~The results reported are:~Mean Baseline frequency of moderate to severe VMS~Mean change in frequency of moderate to severe VMS from baseline to Week 4~Mean change in frequency of moderate to severe VMS from baseline to Week 12" (NCT01101841)
Timeframe: Week 4 and Week 12

Mean Change From Baseline in Hot Flash Severity at Week 4 and Week 12.

"Subjects recorded the number of hot flashes per week using an electronic diary. Severity score for hot flashes for each subject was calculated as the sum of 2 times the number of moderate hot flashes, plus 3 times the number of severe hot flashes, divided by the total number of moderate and severe hot flashes.~Weekly Severity Score = (2•Fm +3•FS)/(Fm + FS) Daily Severity Score = {(2•F) m +3•FS)/(Fm + FS)}/7 Where, Fm= Frequency of Moderate Hot Flashes Fs = Frequency of Severe Hot Flashes" (NCT01101841)
Timeframe: Week 4 and Week 12

Percent Daytime and Nighttime Responders, Numerical Rating Scale (NRS)

"Subject's overall improvement in VMS from Baseline assessed using the Numerical Rating Scale (NRS) The NRS is measured on a scale of 0 to 10 on how bothered the subject was by her VMS (0=not bothered at all and 10=very much bothered).~Responders: Subjects with NRS Score of 5 Or Less. Non-Responders: Subjects With NRS Score of Greater than Or Equal to 6." (NCT01101841)
Timeframe: Week 4 and Week 12

Percent Responders Improvement in VMS From Baseline Using the Clinical Global Impression (CGI) Scale.

"Proportion of NRS Responders: Subject's overall improvement in VMS from Baseline was assessed using the Numerical Rating Scale (NRS)~The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill.~Responders: Subjects Achieving a Score of Very Much Improved Or Much Improved Or Minimally Improved.~Non Responders: Subjects with a Score of No Change Or Minimally Worse Or Much Worse Or Very Much Worse." (NCT01101841)
Timeframe: Week 4 and Week 12

Percentage of Responders

Participants reported the number of hot flashes using an electronic diary. Participants who hd a ≥50% reduction in hot flash frequency were defined as responders. The percent of responders is presented below. (NCT01101841)
