Analysis

The CSFQ examines different aspects of sexual functioning through a series of questions that assess the following dimensions:
Sexual Desire/Interest: Evaluates the internal desire for sexual activity and overall erotic inclination.
Sexual Arousal: Assesses the ability to achieve physical and psychological arousal during sexual activity.
Sustaining Arousal: Evaluates the ability to maintain sexual arousal until the completion of the act.
Orgasm: Examines the ability to reach orgasm and the satisfaction derived from it.
Sexual Satisfaction: Evaluates overall satisfaction with sexual activity.
Participants respond to each question using a Likert scale, usually ranging from 1 (never or almost never) to 5 (always or almost always), to indicate the frequency and intensity of their experiences.

Objective

The objective of the CSFQ is to identify and measure changes in sexual functioning that may arise from various factors, such as mental illness, medication use, or other medical conditions. The questionnaire is often used to assess the effects of psychotropic medications or other treatments on sexual health. The results can guide clinical interventions and improve patients’ quality of life.

Scoring

Scoring of the CSFQ is carried out by analyzing responses for each dimension of sexual functioning. Total scores can be used to estimate the overall level of sexual functioning, as well as to monitor changes over time or following therapeutic interventions.
