Those who may be unfamiliar with the technical terms used in this section [mental health aspects of homosexuality] can refer to the brief listing of basic statistical and psychiatric terminology below.
95% CI = 95% confidence that the population value lies in the given range.
Adjusted OR = Adjusted odds ratio, which is the odds ratio (see below) adjusted for demographic variables.
= a measure of the strength of the difference between two groups. Minus or plus signs indicate direction of difference, not magnitude of difference; no sign means plus by default. The value (ignoring the sign preceding it) of the effect size is interpreted as follows: an effect size (d) between 0 and 0.2 is small (d = 0.2 implies a 14.7% non-overlap between the two trait distributions compared), d = 0.5 represents a medium effect size and corresponds to a 33% non-overlap between the two trait distributions compared, and d greater than 0.8 represents a large effect size (d = 0.8 corresponds to a 47.4% non-overlap between the two trait distributions compared).
= Odds ratio, which is the number of times something is more likely to occur. For instance, an OR = 1.92 refers to a nearly two-fold greater likelihood of an outcome.
p < 0.05
= the probability that the difference is due to chance is less than 0.05 parts in 1, i.e., less than 5 parts in 100, or less than 5%. Similarly, p < 0.001 implies that the probability that the difference is due to chance is less than one part in a thousand. If p > 0.05, then the result is usually considered non-significant from a statistical standpoint, although it may still have some significance if there is a trend toward a difference not caused by chance.
= correlation coefficient; a measure of the tendency of one variable to covary with another; r ranges from -1 to 1; r values close to the extremes of this range imply a strong correlation, whereas those close to the middle of this range, i.e. zero, imply little to no correlation. Correlation does not necessarily imply causation.
SD = Standard deviation, which is a measure of dispersion around the mean. In a normal distribution (bell-shaped curve), 1 SD contains about 68% of the values, 2 SDs contain about 95% of the values, and 3 SDs contain about 99% of the values around the mean.
: Attention deficit hyperactivity disorder; a syndrome characterized by impulsiveness, hyperactivity, and short attention span, which often leads to learning disabilities and various behavioral problems; usually appears in childhood but sometimes persists in adulthood.
: In psychology - feeling or emotion as distinguished from cognition, thought, or action.
: Progressive mental deterioration characterized by confusion, disorientation, loss of memory, impaired ability to calculate, and visual-spatial deficits. It usually begins in late middle life and results in death in 5-10 years. Alzheimer's accounts for some 60-70% of senile dementias.

: a chronic morbid disorder involving repeated and secretive episodic bouts of eating characterized by uncontrolled rapid ingestion of large quantities of food over a short period of time (binge eating), followed by self-induced vomiting, use of laxatives or diuretics, fasting, or vigorous exercise in order to prevent weight gain. It is often accompanied by feelings of guilt, depression, or self-disgust.
Canalization of development
: Channeling of development along species-stable pathways , i.e., reducing trait variability.
: An antipsychotic agent with antiemetic, antiadrenergic, and anticholinergic actions. It depresses conditioned reflexes and reduces blood pressure.

Characterized by disorientation, impaired memory, impaired judgment, lowered intellect, and a shallow labile (changing) affect.
: A disturbance or disruption of development.
: A cardioactive steroid glycoside used in the treatment of congestive heart failure.
: In psychology - An unconscious process by which a group of mental processes is separated from the rest of the thought processes, resulting in an independent functioning of these processes and a loss of the usual relationships; for example, a separation of affect from cognition.

: An emotional disorder characterized by euphoria or irritability, increased psychomotor activity, rapid speech, flight of ideas, decreased need for sleep, distractibility, grandiosity, and poor judgment; usually occurs in bipolar disorder.
: Examples - bipolar disorder, major depression, and dysthymia.
Multiple personality disorder
: A dissociative disorder in which two or more distinct conscious personalities alternately prevail in the same person, without any personality being aware of the other; typically a dubious diagnosis.
: A mental disorder primarily characterized by anxiety and not resulting from any apparent brain lesion; in contrast to the psychoses, persons with a neurosis do not exhibit gross distortion of reality or disorganization of personality. Hypochondria and neurasthenia are examples of some neuroses.

: Condition characterizing a psychopath.
: Plural for psychosis.
: A mental and behavioral disorder causing gross distortion or disorganization of a person's mental capacity, affective response, capacity to recognize reality, and ability to communicate with or/and relate to others to an extent that interferes with the person's capacity to cope with the ordinary demands of everyday life. The psychoses are divided into two major classifications according to their origins: 1) those associated with organic brain syndromes (e.g., Korsakoff's syndrome), and 2) those less strictly organic and having some functional component(s) (e.g., schizophrenia). Although psychosis is a generic term for a variety of insanities, schizophrenias are the most common forms of psychoses.
: Relating to or affected by psychosis.
: An impulse control disorder where an individual often fails to resist the urge to start fires.
: A highly variable disorder characterized by disordered perception, disordered thought (hallucinations and delusions), and extensive withdrawal of the individual's interest from other people and the outside world and the investment of it in his own; a form of psychosis. Psychiatrists usually talk about schizophrenias rather than schizophrenia given the variability of this disorder.
: The process by which psychological needs are supposedly expressed in physical symptoms that do not have a detectable or known organic basis. Alternatively, it refers to the tendency to be overly sensitive to and complain of relatively mild physical problems and complaints.
: An inhibitor of bacterial folic acid synthesis, which has been highly effective against pneumococcal, staphylococcal, streptococcal, E. coli, and Klebsiella pneumoniae infections, and also useful in acute gonococcal arthritis.

Muscular tics typically involve eye blinking, facial grimacing, head jerking, tongue protrusion, sniffing, hopping, skipping, or throat clearing. Vocal tics typically involve stuttering-like blocks in speech fluency, uttering of sounds or words, or obscenities (less than 10% of those afflicted).
: A disorder characterized by repeat abnormal muscular movements or vocalizations (tics) that tend to occur in long-term-unpredictable bouts or bursts, start from early childhood, and last a lifetime, although there is some improvement in young adulthood.
