Are the factors that affect sexual desire very complex? What are the characteristics of sexual desire

The factors that affect sexual desire are very complex, and the most common abnormal sexual desire in clinical practice is low sexual desire. Reproductive endocrine status, gender, age, physical condition, nutritional status, emotions with partners, dietary habits, smoking and drinking habits, education level, religious beliefs, cultural background, growth environment, work stress, interpersonal relationships, and medication use can all affect the strength of sexual desire. At present, there is no clear definition of sexual desire. CCMD-3 focuses on the functional reduction of sexual interest and activity in the definition of decreased sexual desire, and requires a duration of more than 3 months. The ICD-10 definition of decreased or absent libido focuses on: loss of libido independent of sexual pleasure or arousal and completion of sexual activity. Sexual desire disorders in DSM-IV include: low sexual desire, sexual aversion, strong sexual desire or Sexual addiction. The definition of low libido is not listed in both DSM-III and DSM-IV. To accurately evaluate the strength of sexual desire, it is first necessary to clarify the definition of sexual desire. We can summarize sexual desire as the desire to actively or passively engage in intimate contact with others and engage in sexual activities related to sexual behavior under various stimuli both inside and outside the body. It is not only a sexual motivation or a driving force that actively obtains sexual satisfaction through sexual behavior, but also a capacity to passively accept sexual behavior and obtain sexual satisfaction.

Based on the above understanding, sexual desire needs to meet the following characteristics: (1) sexual desire is a desire to obtain sexual satisfaction; (2) Its means are through sexual behavior or related activities, such as intimacy, embrace, kissing, Sexual fantasy, masturbation, sexual dreams, etc; (3) It can be pursued actively or endured passively; (4) There must be stimulation, which may be a change in the level of sexual hormones in the body or external stimuli such as sound and color. According to the definition and connotation of sexual desire, it is preliminarily divided into four categories and an item development scale is proposed. Sexual desire can fluctuate over time, and if the evaluation time span of the scale is too short, the results of the scale will vary too much and be unreliable; Similarly, if the time span is too long, it is difficult for the measured person to accurately recall, and the results are also inaccurate. According to the definition of hypolibido (F52.0) in CCMD-3, to diagnose hypolibido, the symptoms have lasted at least 3 months. We set the time period for measuring the scale as the last three months.

The reliability test of this scale includes retest reliability and homogeneity reliability. Repeat the test on the same respondent and conduct correlation analysis on the test results at different times. Use the correlation coefficient, which is the size of the retest reliability coefficient, to reflect the stability of the measurement results. It is generally believed that the reliability coefficient of the scale can reach 0.70 or above, which is acceptable. If it can exceed 0.80 or above, it is more ideal. The reliability evaluation method for retesting in this study is to randomly select 50 people to retest 2 weeks after the initial test. To meet the methodological requirements of retesting reliability coefficient evaluation, a large number of test subjects are required, and the retesting time is within 1-4 weeks after the initial test. The retest reliability of this scale is 0.931, indicating strong repeatability. The Cronbacha coefficient of this scale is 0.8274, indicating good internal consistency. In a word, the retest reliability and homogeneity reliability of the scale meet the requirements of Surveying.
