" Perhaps as a consequence of this, the toxic effects of MDMA in the monkey involve serotonergic nerve fibers as well as cell bodies, whereas in the rat, only nerve fibers are affected." | 2.38 | Studies of MDMA-induced neurotoxicity in nonhuman primates: a basis for evaluating long-term effects in humans.

"Regulation of neurotoxicants is generally based on setting allowable doses (exposures) by dividing a no observed adverse effect level (NOAEL) by uncertainty factors that hopefully account for interspecies and intraspecies differences for extrapolations of experimental results obtained in animals to humans." | 1.28 | Risk assessment for neurotoxic effects.

"The State-Trait Anxiety Inventory (STAI) is a 20-item self-report measure of intensity of anxiety. Each item consists of a 4-point Likert rating scale ranging from 1 ('Not at all') to 4 ('Very Much So'), with higher scores indicating greater anxiety. Items were summed for a total score that ranged from 20 to 80.~The STAI differentiates between State Anxiety, defined as anxiety experienced in reaction to a specific environmental circumstance, and Trait Anxiety, defined as long-standing nervous affect or anxiety disorder. The use of the trait subscale as the primary outcome measure is intended to target those anxiety symptoms that are chronic and pervasive." (NCT02427568)

The Beck Depression Inventory-II (BDI-II) is a a 21-item self-reported measure of depression according to Diagnostic and Statistical Manual IV (DSM-IV) criteria. Each item is rated on a 4-point Likert scale ranging from 0 to 3. The total score is the sum of 21 items and range from 0 to 63. Score cutoffs indicate: 0-13 minimal depression, 14-19 mild depression, 20-28 moderate depression, and 29-63 severe depression. Higher scores indicate more severe depressive symptoms. (NCT02427568)

The Pittsburgh Sleep Quality Index (PSQI) is a measure of self-reported sleep quality over a one month period. It consists of 19 items with possible responses ranging from zero to four on a five-point scale. The PSQI consists of seven sub-scales: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping medications, and daytime dysfunction. These are all summed to produce a single global scale. Global scores can range from 0 to 21, with higher scores reflecting poorer sleep quality, and a score below 5 indicating good sleep quality.

The Posttraumatic Growth Inventory (PTGI) is a 21-item self-report measure of perceived growth or benefits occurring after a traumatic event. It contains five subscales; relationship to others, new possibilities, personal strength, spiritual change, and appreciation of life. Questions are answered on a scale from 0 (I did not experience this change) to 5 (I experienced this change to a great degree). Items are added to calculate the total PTGI score which ranges from 0 to 105, with higher scores indicative of greater growth. (NCT02427568)

"The Self-Compassion Scale (SCS) is a 26-item self-reported questionnaire that assesses how respondents relate to themselves and treat themselves during difficult or painful experiences. Items are scored along a 5-point Likert-type scale ranging from 1 almost never to 5 almost always. The SCS has six component (subscale) scores: self-kindness, self-judgment, common humanity, isolation, mindfulness, and over-identification. Subscale scores are calculated by computing the mean of subscale item responses.~A total self-compassion score is calculated by the sum of the subscale scores and range from 24 to 120 with higher scores indicating greater self compassion. Higher scores have been found to correlate with positive mental health outcomes, as well as decreased depression and anxiety." (NCT02427568)

"The state subscale of the STAI (STAI-S) is a 20-item self-reported scale which assesses subjects' levels of transient, situationally oriented, anxiety. Like the trait subscale, participants respond to each item on the state subscale by selecting a response from a 4-point Likert scale ranging from 4 (Not at all) to 1 (Very much so), with higher scores indicating greater anxiety. Items were summed for a total score that ranged from 20 to 80.~The STAI differentiates between State Anxiety, defined as anxiety experienced in reaction to a specific environmental circumstance, and Trait Anxiety, defined as long-standing nervous affect or anxiety disorder. The use of the trait subscale as the primary outcome measure is intended to target those anxiety symptoms that are chronic and pervasive." (NCT02427568)

"The Death Attitudes Profile (DAP) is a 32-item self-reported questionnaire that assesses individual attitudes and beliefs about death and dying. Each item on the scale is rated along a 7-point Likert scale ranging from strongly disagree (score of 1) to strongly agree (score of 7), with higher scores indicating more positive attitudes toward death.~The DAP consists of 5 dimensions: fear of death (7 items summed with total scores ranging from 7 to 49), death avoidance (5 items summed with total scores ranging from 5 to 35), neutral acceptance (5 items summed with total scores ranging from 5 to 35), approach acceptance (10 items summed with total scores ranging from 10 to 70), and escape acceptance (5 items summed with total scores ranging from 5 to 35). For each dimension, a mean scale score can be computed by dividing the total scale score by the number of items forming each scale." (NCT02427568)

The Functional Assessment of Chronic Illness Therapy Scale (FACIT-Sp) is a 27-item self-report measure of quality of life issues specifically relevant to individuals with a chronic or life-threatening illness or condition. The core questionnaire consists of four subscales: Physical Well-being, Social/Family Well-being, Emotional Well-being, and Functional Well-being. Responses range from 0 (not at all) to 4 (very much), with higher scores indicating greater well-being. For each subscale, total scores were summed and range from 0 to 16. (NCT02427568)
