Development and Initial Psychometric Evaluation of CIAECSA: A Comprehensive Questionnaire on Attitudes, Experiences, and Contexts of Adolescent Sexuality.

Background/

Objectives

Adolescent sexuality is multidimensional, yet brief instruments assessing attitudes, experiences, and contextual influences from a biopsychosocial perspective remain limited. This study aimed to develop the Comprehensive Questionnaire on Attitudes, Experiences, and Contexts of Adolescent Sexuality (CIAECSA) and examine its content validity, comprehensibility, feasibility, internal consistency, and exploratory internal structure.

Methods

A cross-sectional methodological study comprised three phases: theoretical delimitation and generation of 30 initial items; content evaluation by nine experts and semantic validation with 26 adolescents; and pilot administration to 51 adolescents from educational settings in Toledo, Spain. The pilot sample included 35 females (68.6%), 15 males (29.4%), and one gender-fluid participant (2.0%), aged 12-17 years (mean = 14.41; SD = 1.72). Content validity, perceived clarity, feasibility, Cronbach's alpha, and principal component analysis with Varimax rotation were examined.

Results

The final questionnaire comprised 18 items across three domains: sexuality/gender/anatomy, emotional/physical pain, and self-care/environment. The scale-level Content Validity Index (S-CVI/Ave) was 0.955, and mean perceived clarity was 4.53/5. The mean completion time was 5.52 min. Cronbach's alpha was 0.800, 0.780, and 0.740 for the three domains and 0.715 for the total scale. The KMO was 0.659, Bartlett's test was significant (p < 0.001), and an exploratory three-component solution, examined against the prespecified domains, explained 51.4% of the variance.

Conclusions

The findings provide favorable evidence of content validity, comprehensibility, feasibility, and internal consistency. The CIAECSA may help identify educational needs and psychosocial factors related to adolescent sexuality, although its internal structure and additional measurement properties require examination in larger, balanced, and independent samples.
